2.3 The `trunk' Directory

- - - -

2.3.1 Goals

- -

This directory implements the Subversion's trunk concept in a -trunk, branches, tags repository structure. -

- - -

2.3.2 Description

- -

The `trunk/' directory structure is the main development line -inside the CentOS Artwork Repository and organizes the following -sections: -

-
-
Identity
-

This section organizes image production in different formats and some -non-image formats like XHTML and text files, as well. This is the -perfect place to consolidate The CentOS Artwork SIG. If you are -interested in producing art works for The CentOS Project, this place -is for you. -

-

See section The `trunk/Identity' Directory, for more information. -

-
-
Manual
-

This section organizes the CentOS Artwork Repository Manual -(i.e., the documentation manual you're reading right now). If you are -interested on improving The CentOS Artwork Repository Manual, in this -place you'll find the Texinfo documentation structure you need to work -with. -

-

See section The `trunk/Manual' Directory, for more information. -

-
-
Scripts
-

This section organizes production of automation scripts specially -designed to automate most frequent tasks in the repository (e.g., -image rendition, documenting directory structures, translating -content, etc.). If you can't resist the idea of automating repeatable -tasks, then take a look here. -

-

See section The `trunk/Scripts' Directory, for more information. -

-
-
Locales
-

This section organizes production of translation messages for -Identity, Documentation and Scripts. This place -is perfect to consolidate The CentOS Translation SIG. If you -love translating, you'll find lot of messages waiting for you to -translate here. -

-

See section The `trunk/Locales' Directory, for more information. -

-
- - - -

2.3.3 Usage

- -

It seems to be no other use for this directory but to organize the -sections described above. -

2.4 The `trunk/Identity' Directory

- - - -

2.4.1 Goals

- -

The `trunk/Identity' directory structure implements The -CentOS Project Corporate Identity. -

- - -

2.4.2 Description

- -

The CentOS Project corporate identity is the "persona" of the -organization known as The CentOS Project. The CentOS Project -corporate identity plays a significant role in the way the CentOS -Project, as organization, presents itself to both internal and -external stakeholders. In general terms, the CentOS Project corporate -visual identity expresses the values and ambitions of the CentOS -Project organization, its business, and its characteristics. -

-

The CentOS Project corporate identity provides visibility, -recognizability, reputation, structure and identification to The -CentOS Project organization by means of Corporate Design, -Corporate Communication, and Corporate Behaviour. -

- - -

2.4.2.1 Corporate Design

- -

The CentOS Project corporate design is applied to every single visual -manifestations The CentOS Project as organization wants to express its -existence. Examples of the most relevant visual manifestations inside -The CentOS Project are The CentOS Distribution, The -CentOS Web and The CentOS Stationery. -

-

The CentOS Project corporate design is organized in the following -work-lines: -

-
-
The CentOS Brand
-

The CentOS Brand is the name or trademark that connects the producer -with their products. In this case, the producer is The CentOS Project -and the products are The CentOS Project visual manifestations. -

-

See section The `trunk/Identity/Brands' Directory, for more information. -

-
-
The CentOS Colors
-
-

The CentOS Fonts provides the color information used along The CentOS -Project visual manifestations. -

-

See section The `trunk/Identity/Colors' Directory, for more information. -

-
The CentOS Fonts
-
-

The CentOS Fonts provides the typography information used along The -CentOS Project visual manifestations. -

-

See section The `trunk/Identity/Fonts' Directory, for more information. -

-
The CentOS Themes
-
-

The CentOS Themes provides structural information and visual style -information, as well, used along The CentOS Project visual -manifestations. -

-

See section The `trunk/Identity/Themes' Directory, for more information. -

-
- - - -

2.4.2.2 Corporate Communication

- -

The CentOS Project corporate communication is based on community -communication. In that sake, the following media are available for -corporate communication: -

- - - - -

2.4.2.3 Corporate Behaviour

- -

The CentOS Project corporate behaviour is based on community -behaviour. -

- - -

2.4.2.4 Corporate Structure

- -

The CentOS Project corporate structure is based on a monolithic -corporate visual identity structure. In this structure, we use one -unique name (The CentOS Brand) and one unique visual style (The CentOS -Theme) in all The CentOS Project visual manifestations. -

-

Inside a monolithic corporate visual identity structure, internal and -external stakeholders use to feel a strong sensation of uniformity, -orientation, and identification with the organization. No matter if -you are visiting web sites, using the distribution, or acting on -social events, the one unique name and one unique visual style -connects them all to say: Hey! we are all part of The CentOS -Project. -

-

Other corporate structures have been considered as well, but they -introduce visual contradictions we need to be aware of. In that sake, -lets describe the idea of: Producing one different visual style -for each major release of The CentOS Distribution. -

-

The CentOS Project maintains near to four different major releases of -The CentOS Distribution parallely in time and that fact makes one part -of The CentOS Project structural design, but just one part, not the -complete structural design. In order to produce the correct corporate -structure for The CentOS Project we need to concider all the visual -manifestations The CentOS Project is made of, not just one of them. -

-

If one different visual style is used for each major release of The -CentOS Distribution, which one of those different visual styles would -be used to cover the remaining visual manifestations The CentOS -Project is made of. Would we end up with four different visual styles, -one for each distribution? In that case, why The CentOS Distribution -we use shows one visual style, The CentOS Web sites another and The -CentOS Stationery even another completly different one? Isn't them -all part of the same project? -

-

Probably you be thinking, that's right, but The CentOS Brand connects -them all already, why would we need to join them up into the same -visual style too, isn't it more work to do, and harder to maintain? -

-

Harder to maintain, more work to do, it is probably. Specially when -you consider that The CentOS Project has proven stability and -consistency through time and that, certainly, didn't come through -swinging magical wangs or something but hardly working out to automate -tasks and so providing maintainance through time. Said that, we -consider that The CentOS Project visual structure should be consequent -with such stability and consistency tradition. It is true The CentOS -Brand does connect all the visual manifestations it is present on, but -that connection would be stronger if one unique visual style backups -it. In fact, whatever thing you do to strength the visual connection -among The CentOS Project visual manifestations would be very good in -favor of The CentOS Project recognition. -

-

Obviously, having just one visual style in all visual manifestations -for eternity would be a very boring thing and would give the idea of a -visually dead project. So, there is no problem on creating a brand new -visual style for each new major release of The CentOS Distribution, in -order to refresh The CentOS Distribution visual style; the problem -does is in not propagating the brand new visual style created for the -new release of CentOS Distribution to all other visual manifestations -The CentOS Project is made of, in a way The CentOS Project could be -recognized no matter what visual manifestation be in front of us. Such -lack of uniformity is what introduces the visual contradition we are -precisely trying to solve by mean of themes production in the CentOS -Artwork Repository. -

- - -

2.4.3 Usage

- -

The `trunk/' directory structure is organized in -renderable and non-renderable directories. Generally, -renderable directories contain two non-renderable directories inside, -one to store design templates (the `Tpl/' directory), and other -to store the content produced (the `Img/' directory). -

-

In order to produce content inside rendereble directories, you can use -the following command: -

-
centos-art render trunk/Identity/Path/To/Dir
-
-
Warning

Warning

If the centos-art command-line -is not found in your workstation, it is probably because you haven't -prepared it for using The CentOS Artwork Repository yet. -See section The `trunk/Scripts/Bash/Cli/Functions/Verify' Directory, for more -information. -

- -

This command takes one design template from the template directory and -creates an instance of it in order to apply translation messages on -it, if any. Later, using the design template instance, the command -renders the final content based on whether the design template -instance is a SVG file or a Docbook file. If the design template -instace is a SVG file, the final content produced is a PNG image. On -the other hand, if the design template instance is a Docbook file, the -final content produced is a XHTML file. Final content is stored in the -image directory using the design template directory paths as referece. -The rendition flow described so far is known as the -base-rendition flow. -

-

Besides the base-rendition flow, the centos-art provides the -post-rendition and last-rendition flows. The -post-rendition flow is applied to files produced as result of -base-rendition flow under the same directory structure. For example, -you can use post-rendition action to convert the PNG base output into -different outputs (e.g., JPG, PDF, etc.) before passing to process the -next file in the same directory structure. The last-rendition flow is -applied to all files produced as result of both base-rendition and -post-rendition flows in the same directory structure, just before -passing to process a different directory structure. For example, the -`Preview.png' image from Ksplash component is made of three -images. In order to build the `Preview.png' image through -centos-art we need to wait for all the three images the -`Preview.png' image is made of to be rendered, so we can combine -them all together into just one image (i.e., the `Preview.png' -image). This is something we can't do using post-rendition flow. -

-

Inside `trunk/Identity' directory structure, you can find that -base-rendition, post-rendition and last-rendition flows can be -combined to build directory-specific rendition. The -directory-specific rendition exists to automatically process specific -renderable directories in very specific ways. Using directory-specific -rendition speeds up production of different components like Syslinux, -Grub, Gdm, Kdm and Ksplash that require intermediate formats or even -several independent files, in order to reach its final construction. -Directory-specific rendition is a way to programmatically describe how -specific art works are built in and organized inside The CentOS -Artwork Repository. Such descriptions have been added to -centos-art command-line to let you produce them all with -just one single command, as fast as your machine can be able to handle -it. -

-

See section The `trunk/Scripts/Bash/Cli/Functions/Identity' Directory, for more -information about the identity functionality of -centos-art command-line interface. -

See http://en.wikipedia.org/Corporate_identity (and related -links), for general information on corporate identity. -

-

Specially useful has been, and still be, the book Corporate -Identity by Wally Olins (1989). This book provides many conceptual -ideas we've used as base to build The CentOS Artwork Repository. -

2.7 The `trunk/Identity/Fonts' Directory

- - - -

2.7.1 Goals

- -

This section exists to organize digital typographies used by the -CentOS project. -

- - -

2.7.2 Description

- - - -

2.7.3 Usage

- -

The CentOS corporate identity is attached to `DejaVu LGC' -font-family. Whatever artwork you design for CentOS project, that -requires typography usage, must be done using `DejaVu LGC' -font-family. -

-
-
Recommendation-1:
-
-

For screen desings (e.g., anything that final destination will never -be printed on paper or any medium outside computer screens) use -`DejaVu LGC Sans' font-family. -

-
-
Recommendation-2:
-
-

For non-screen designs (e.g., anything that final desition will be -printed on paper or any other medium outside computer screens) use -`DejaVu LGC Serif' font-family. As convenction files described in -this rule are stored under `Stationery' directories. -

-
- -

The only execption for the two recommendations above is the typography -used inside CentOS logo. The CentOS logo is the main visual -representation of the CentOS project so the typography used in it must -be the same always, no matter where it be shown. It also has to be -clear enough to dismiss any confussion between similar typefaces -(e.g., the number one (1) sometimes is confuesed with the letter -`el' (l) or letter `ai' (i)). -

-

As CentOS logo typography convenction, the word `CentOS' uses -`Denmark' typography as base, both for the word `CentOS' and -the phrase `Community Enterprise Operating System'. The phrase -size of CentOS logo is half the size in poits the word `CentOS' -has and it below `CentOS' word and aligned with it on the left. -The distance between `CentOS' word and phrase `Community -Enterprise Operating System' have the size in points the phrase has. -

-

When the CentOS release brand is built, use `Denmark' typography -for the release number. The release number size is two times larger -(in height) than default `CentOS' word. The separation between -release number and `CentOS' word is twice the size in points of -separation between `CentOS' word and phrase `Community -Enterprise Operating System'. -

-

Another component inside CentOS logo is the trademark symbol (TM). -This symbol specifies that the CentOS logo must be consider a product -brand, even it is not a registered one. The trademark symbol uses -DejaVu LGC Sans Regular typography. The trademark symbol is aligned -right-top on the outter side of `CentOS' word. The trademark -symbol must not exceed haf the distance, in points, between -`CentOS' word and the release number on its right. -

-

It would be very convenient for the CentOS Project and its community -to to make a registered trademark (®) of CentOS logo. To make a -register trademark of CentOS Logo prevents legal complications in the -market place of brands. It grants the consistency, through time, of -CentOS project corporate visual identity. -

-
info

Note

The information about trademarks and corporate identity -is my personal interpretation of -http://en.wikipedia.org/Corporate_identity and -http://en.wikipedia.org/Trademark description. If you have -practical experiences with these affairs, please serve yourself to -improve this section with your reasons. -

1.1 History

- -

This section records noteworthy changes of CentOS Artwork Repository. -

- -

2008

- -

The CentOS Artwork Repository started at CentOS Developers mailing -list (centos-devel@centos.org) during a discussion about how -to automate the slide images of Anaconda. In such discussion, Ralph -Angenendt rose up his hand to ask: Do you have something to show? -

-

To answer the question, Alain Reguera Delgado posted a bash script to -produce slide images in different languages --together with the -proposition of creating a Subversion centralized repository where -translations and image production could be distributed inside The -CentOS Community--. -

-

Karanbirn Sighn considered the idea intresting and provides the -infrastructure to support the effort. This way both the CentOS Artwork -SIG and the CentOS Artwork Repository were created. -

- - -

Once the CentOS Artwork Repository was available, Alain Reguera -Delagdo uploaded the bash script for rendering Anaconda slides and -Ralph Angenendt documented the script very well. -

-

Once the rendition script and its documentation were available online, -translators started to download working copies of CentOS Artwork -Repository to produce slide images in their own languages. -

- -

2009

- -

The rendition script is designed to take one SVG file, apply one SED -file with replacement command inside to produce one SVG translated -instance that is used to produce one translated PNG image by means of -Inkscape program. The rendition script was named render.sh -and it is copied to each directory structure that requires such -process to produce images. -

-

Furthermore, functionalies are centralized in a common placed and -linked from different directory structures. There is no need to have -the same code in different directory structures if can have it in just -one place and then create links to it. -

-

Start to implement concepts about corporate identity. As referece it -is used Wikipedia (http://en.wikipedia.org/Corporate_identity) -and the book Corporate Identity by Wally Olins (1989). The main -goal of render.sh becomes to: automate production of a -monolithic corporate visual identity structure based on The CentOS -Mission and The CentOS Release Schema. -

-

Around March, Alain Reguera Delgado is out of Internet for an -undefined amount of time, but continues developing the idea of CentOS -Artwork Repository and the rendition script off-line. -

-

Most of the work I propose from this time on is my own responsability. -I keep myself thinking to be part of the CentOS Artwork SIG and in -that sake, I use the personal pronoun we to refer what I do as -part of the group hoping someday to share this work with you again and -improve it together. -

-

The CentOS Artwork Repository documentation starts to take form in -LaTeX format. -

- -

2010

- -

The render.sh is removed from the repository directory -structures and the centos-art.sh script is used instead. The -centos-art.sh is created to be a command-line interface that -automate most frequent tasks inside the repository and can be called -anywhere inside the repository or outside it; whenever it points to a -directory structure inside the repository. At the very first moments -of using centos-art.sh command-line, it used to have the -following using form: -

-
centos-art function --action=path/to/dir
-
-

Inside the rendition script, functionalities started to get identified -and separated one another. For example, when images are rendered, -there is no need to load manual functionality. There are now common -functionalities and specific functionalities. Common functionalities -are loaded when the script is initiated and are available to specific -functionalities. -

-

Start using getopt to handle command-line options. -

-

The repository directory structure is optimized to continue -implementing corporate identity concepts and the centos-art -command-line. -

- -

2011

- -

The `trunk/Translation' directory structure is removed. The -`trunk/Locales' directory structure is used instead to store locale -information. -

-

The `.sed' translation files are no longer used, scalable vector -graphics are used instead. Translation messages take place by means -of xml2po and gettext. With xml2po translatable strings are retrived -from `.svg' files and stored inside gettext `.pot' and `.po' files for -translators to edit. Finally, xml2po is used again to build the -temporal design model translated instance which the final `.png' image -is built from. -

-

Inside centos-art.sh, update command-line arguments and -options parsing. Keep using getopt to parse options passed -in the command-line, but change the way centos-art.sh is -called from. The following form is used: -

-
centos-art function path/to/dir --options
-
-

Start using verbs to name the centos-art.sh functionalities. -

-

Organize centos-art.sh functionalities in "administrative" -functions and "productive" functions. Administrative functions -cover actions like: copying, deleting and renaming directory -structures. Also, preparing your workstation for using -centos-art command-line, make backups of the distribution -theme currently installed, installing themes created inside The -CentOS Artwork repository and restoring themes from backup. On the -other hand, productive functions cover actions like: content -rendition, content localization, content documentation and content -maintainance. -

2.16 The `trunk/Identity/Models/Tpl/Promo/Web' Directory

- - - -

2.16.1 Goals

- -

Organize scalable vector graphics (svg) to help describe the CentOS -web environment. -

- - -

2.16.2 The CentOS web environment

- -

Inside CentOS corporate identity, the CentOS web environment is -considered a promotion component. The CentOS web environment is formed -by a central web application --to cover base needs (e.g., per-major -release information like release notes, lifetime, downloads, -documentation, support, security advisories, bugs, etc.)-- and many -different free web applications --to cover specific needs (e.g., -wiki, mailing lists, etc.)--. -

-

The CentOS web environment is addressed to solve the following issues: -

- - -

The CentOS project is attached to a monolithic corporate visual -identity (see section The `trunk/Identity' Directory), where all visual manifestations -have one unique name and one unique visual style. This way, the CentOS -web environment has one unique name (the CentOS brand) and one unique -visual style (the CentOS default theme) for all its visual -manifestations, the web applications in this case. -

-

Since a maintainance point of view, achiving the one unique visual -style inside CentOS web environment is not a simple task. The CentOS -web environment is built upon many different web applications which -have different visual styles and different internal ways to customize -their own visual styles. For example: MoinMoin, the web application -used to support the CentOS wiki (http://wiki.centos.org/) is -highly customizable but Mailman (in its 2.x.x serie), the web -application used to support the CentOS mailing list, doesn't -support(1) a customization system that separates -presentation from logic, similar to that used by MoinMoin. -

-

This visual style diversity complicates our goal of one unique visual -style for all web applications. So, if we want one unique visual style -for all web applications used, it is innevitable to modify the web -applications in order to implement the CentOS one unique visual style -customization in them. Direct modification of upstream applications is -not convenient because upstream applications come with their one -visual style and administrators take the risk of loosing all -customization changes the next time the application be updated (since -not all upstream web applications, used in CentOS web environment, -separate presentation from logic). -

-

To solve the "one unique visual style" issue, installation and -actualization of web applications --used inside CentOS web -environment-- need to be independent from upstream web applications -development line; in a way that CentOS web environment administrators -can install and update web applications freely without risk of loosing -the one unique visual style customization changes. -

-

At the surface of this issue we can see the need of one specific yum -repository to store CentOS web environment customized web applications. -

- - -

2.16.2.1 Design model (without ads)

- - - -

2.16.2.2 Design model (with ads)

- - - -

2.16.2.3 HTML definitions

- - - -

2.16.2.4 Controlling visual style

- -

Inside CentOS web environment, the visual style is controlled by the -following compenents: -

-
-
Webenv header background
-
trunk/Identity/Themes/Motifs/$THEME/Backgrounds/Img/1024x250.png
-
-
-
CSS definitions
-
trunk/Identity/Themes/Models/Default/Promo/Web/CSS/stylesheet.css
-
-
- - - -

2.16.2.5 Producing visual style

- -

The visual style of CentOS web environment is defined in the following -files: -

-
trunk/Identity/Themes/Motifs/$THEME/Backgrounds/Xcf/1024x250.xcf
-trunk/Identity/Themes/Motifs/$THEME/Backgrounds/Img/1024x250.png
-trunk/Identity/Themes/Motifs/$THEME/Backgrounds/Img/1024x250-bg.png
-trunk/Identity/Themes/Motifs/$THEME/Backgrounds/Tpl/1024x250.svg
-
-

As graphic designer you use `1024x250.xcf' file to produce -`1024x250-bg.png' file. Later, inside `1024x250.svg' file, -you use the `1024x250-bg.png' file as background layer to draw -your vectorial design. When you consider you artwork ready, use the -centos-art.sh script, as described below, to produce the -visual style controller images of CentOS web environment. -

-
centos-art render --entry=trunk/Identity/Themes/Motifs/$THEME/Backgrounds --filter='1024x250'
-
-

Once you have rendered required image files, changing the visual style -of CentOS web environment is a matter of replacing old image files -with new ones, inside webenv repository file system structure. The -visual style changes will take effect the next time customization line -of CentOS web applications be packaged, uploded, and installed from -[webenv] or [webenv-test] repositories. -

- - -

2.16.2.6 Navigation

- -

Inside CentOS web environment, the one-step navegation between web -applications is addressed using the web environment navigation bar. -The web environment navigation bar contains links to main applications -and is always visible no matter where you are inside the web -environment. -

- - -

2.16.2.7 Development and release cycle

- -

The CentOS web environment development and relase cycle is described -below: -

-
-
Download
-
-

The first action is download the source code of web applications we -want to use inside CentOS web environment. -

-
Important

Important

The source location from which web application are -downloaded is very important. Use SRPMs from CentOS [base] -and [updates] repositories as first choise, and third party -repositories (e.g. RPMForge, EPEL, etc.) as last resource. -

- -
-
Prepare
-
-

Once web application source code has been downloaded, our duty is -organize its files inside `webenv' version controlled repository. -

-

When preparing the structure keep in mind that different web -applications have different visual styles, and also different ways to -implement it. A convenient way to organize the file system structure -would be create one development line for each web application we use -inside CentOS web environment. For example, consider the following -file system structure: -

-
https://projects.centos.org/svn/webenv/trunk/
-|-- WebApp1/
-|   |-- Sources/
-|   |   `-- webapp1-0.0.1/
-|   |-- Rpms/
-|   |   `-- webapp1-0.0.1.rpm
-|   |-- Srpms/
-|   |   `-- webapp1-0.0.1.srpm
-|   `-- Specs/
-|       `-- webapp1-0.0.1.spec
-|-- WebApp2/
-`-- WebAppN/
-
-
-
Customize
-
-

Once web applications have been organized inside the version -controlled repository file system, use subversion to create the CentOS -customization development line of web applications source code. For -example, using the above file system structure, you can create the -customization development line of `webapp1-0.0.1/' with the -following command: -

-
svn cp trunk/WebApp1/Sources/webapp1-0.0.1 trunk/WebApp1/Sources/webapp1-0.0.1-webenv
-
-

The command above creates the following structure: -

-
https://projects.centos.org/svn/webenv/trunk/
-|-- WebApp1/
-|   |-- Sources/
-|   |   |-- webapp1-0.0.1/
-|   |   `-- webapp1-0.0.1-webenv/
-|   |-- Rpms/
-|   |   `-- webapp1-0.0.1.rpm
-|   |-- Srpms/
-|   |   `-- webapp1-0.0.1.srpm
-|   `-- Specs/
-|       `-- webapp1-0.0.1.spec
-|-- WebApp2/
-`-- WebAppN/
-
-

In the above structure, the `webapp1-0.0.1-webenv/' directory is -the place where you customize the visual style of -`webapp1-0.0.1/' web application. -

-
Info

Tip

Use the diff command of Subversion between -CentOS customization and upstream development lines to know what you -are changing exactly. -

- -
-
Build packages
-
-

When web application has been customized, build the web application -RPM and SRPM using the source location with `-webenv' prefix. -

-
https://projects.centos.org/svn/webenv/trunk/
-|-- WebApp1/
-|   |-- Sources/
-|   |   |-- webapp1-0.0.1/
-|   |   `-- webapp1-0.0.1-webenv/
-|   |-- Rpms/
-|   |   |-- webapp1-0.0.1.rpm
-|   |   `-- webapp1-0.0.1-webenv.rpm
-|   |-- Srpms/
-|   |   |-- webapp1-0.0.1.srpm
-|   |   `-- webapp1-0.0.1-webenv.srpm
-|   `-- Specs/
-|       |-- webapp1-0.0.1.spec
-|       `-- webapp1-0.0.1-webenv.spec
-|-- WebApp2/
-`-- WebAppN/
-
-
-
Release for testing
-
-

When the customized web application has been packaged, make packages -available for testing and quality assurance. This can be achives using -a [webenv-test] yum repository. -

-
info

Note

The [webenv-test] repository is not shipped inside -CentOS distribution default yum configuraiton. In order to use -[webenv-test] repository you need to configure it first. -

- -

If some problem is found to install/update/use the customized version -of web application, the problem is notified somewhere (a bugtracker -maybe) and the customization face is repated in order to fix the -problem. To release the new package add a number after `-webenv' -prefix. For example, if some problem is found in -`webapp1-0.0.1-webenv.rpm', when it be fixed the new package will -be named `webapp1-0.0.1-webenv-1.rpm'. If a problem is found in -`webapp1-0.0.1-webenv-1.rpm', when it be fixed the new package -will be named `webapp1-0.0.1-webenv-2.rpm', and so on. -

-

The "customization -- release for testing" process is repeated -until CentOS quality assurance team considers the package is ready for -production. -

-
-
Release for production
-
-

When customized web application packages are considered ready for -production they are moved from [webenv-test] to [webenv] repository. -This action is commited by CentOS quality assurance team. -

-
info

Note

The [webenv] repository is not shipped inside CentOS -distribution default yum configuraiton. In order to use [webenv] -repository you need to configure it first. -

- - - - - -

2.20.2 Description

- -

Theme models let you modeling characteristics (e.g., dimensions, -translation markers, position of each element on the display area, -etc.) common to all themes. Theme models let you reduce the time -needed when propagating artistic motifs to different visual -manifestations. -

-

Theme models serves as a central pool of design templates for themes -to use. This way you can produce themes with different artistic motifs -but same characteristics. -

- - -

2.20.3 Usage

- -

Inside the framework location above, you find theme models organized -by name. You can add your own theme models to the structure by adding -a directory to the list. By default you have the `See section Default,' and `See section Alternative,' ready-to-use theme models. -

2.21.1 Goals

- - - - - -

2.21.2 Description

- -

CentOS alternative theme models exist for people how want to use a -different visual style on their installations of CentOS distribution. -As the visual style is needed for a system already installed -components like Anaconda are not required inside alternative themes. -Inside alternative themes you find post-installation visual style only -(i.e. Backgrounds, Display Managers, Grub, etc.). CentOS alternative -themes are maintained by CentOS Community. -

2.22 The `trunk/Identity/Themes/Models/Default' Directory

- - - -

2.22.1 Goals

- -

Default Design Models for CentOS Themes provide design models for the -following components: -

-
-
Distribution
-

Design models for CentOS Distribution (e.g., Anaconda, Firstboot, Gdm, -Grub, Gsplash, Kdm, Ksplash, Rhgb and Syslinux, etc.). -See section The `trunk/Identity/Themes/Models/Default/Distro' Directory, for -more information. -

-
-
Concept
-

Design models to illustrate Artistic Motifs Concepts. -See section The `trunk/Identity/Themes/Models/Default/Concept' Directory, for -more information. -

-
-
Promotion
-

Design models for CentOS Promotion stuff (e.g., installation media, -posters, etc.). See section The `trunk/Identity/Themes/Models/Default/Promo' Directory, for more information. -

-
- - - -

2.22.2 Description

- -

This directory implements the concept of Default Design Models -for CentOS Themes. Default Design Models for CentOS Themes provide -the common structural information (e.g., image dimensions, translation -markers, trademark position, etc.) the centos-art script -uses to produce images when no other design model is specified. -

-

Deisgn models in this directory do use the CentOS Release -Brand. The CentOS Release Brand is a combination of both The CentOS -Type and The CentOS Release Schema used to illustrate the major -release of CentOS Distribution the image produced belongs to. -See section The `trunk/Identity/Models/Tpl/Brands' Directory, for more -information. -

- - -

2.22.3 Usage

- -

The CentOS Project maintains near to four different major releases of -CentOS Distribution. Each major release of CentOS Distribution has -internal differences that make them unique and, at the same time, each -CentOS Distribution individually is tagged into the one unique visual -manifestation (i.e., Distribution). So, how could we implement the -monolithic visual structure in one visual manifestation that has -internal difference? -

-

To answer this question we broke the question in two parts and later -combined the resultant answers to build a possible solution. -

-
-
How to remark the internal differences visually?
-
-

Merge both The CentOS Project Release Schema into The CentOS Project -Trademark to build The CentOS Project Release Trademark. The CentOS -Project Release Trademark remarks two things: first, it remarks the -image is from The CentOS Project and second, it remarks which major -release of CentOS Distribution does the image belongs to. -See section The `trunk/Identity/Models/Tpl/Brands' Directory, for more -information on how to develop and improve The CentOS Project Brand. -

-
-
How to remark the visual resemblance?
-
-

Use a common artistic motifs as background for all CentOS Distribution -images. See section The `trunk/Identity/Themes/Motifs' Directory, for more -information. -

-
-
So, combining answers above, we could conclude that:
-
-

In order to implement the CentOS Monolithic Visual Structure on CentOS -Distribution visual manifestations, a CentOS Release Trademark and a -background information based on one unique artistic motif should be -used in all remarkable images The CentOS Distribution visual -manifestation is made of. -

-
- -
Important

Important

Remarking the CentOS Release Schema inside each -major release of CentOS Distribution --or similar visual -manifestations-- takes high attention inside The CentOS -Project corporate visual identity. It should be very clear for -everyone which major release of CentOS Distribution is being used. -

2.24.2 Description

- -

The CentOS Distribution visual style is controlled by image files. -These image files are packaged inside The CentOS Distribution and made -visible once such packages are installed and executed. The way to go -for changing The CentOS Distribution visual style is changing all -those image files to add the desired visual style first and later, -repackage them to make them available inside the final iso files of -CentOS Distribution. -

- - -

2.24.3 Usage

- -

This directory provides organizationl structure to store default -design models for CentOS Themes of CentOS Distribution and so it -should be considered to be used. -

-

When a new component is added to CentOS Distribution, this is the -directory you need to go for specifying design models for image files -inside such component. -

-

The procedure to follow is creatig a directory for each component -using its very same name (e.g., the directory `Anaconda' stores -image files for Anaconda component, the installer program). Inside the -directory, you need to create one scalable vector graphic for each -image file inside the component you want to produce images for. This, -in order to set image dimensions, image file-name, position of -trademarks in the final image, translation markers and whatever common -information you need to have specified in them when rendered by -centos-art script. -

-

Sometimes, between major releases, image files inside packages can be -added, removed or just change their names. In order to describe such -image files variations, the design models directory structure is -organized in the same way the file variations are introduced (i.e., -through The CentOS Project Release Schema). So, each major release of -CentOS Distribution does have its own design model directory structure -in this directory. -

-

When a whole package is removed from one or all CentOS Distribution -major releases, the design models directory structure releated to it -is no longer used. However it could be very useful for historical -reasons. Also, someone could feel motivated enough to keep himself -documenting it or supporting it for whatever reason. -

1.3 Copying Conditions

- -

Inside the CentOS Artwork Repository you can find content branded by -The CentOS Project and content not branded at all. Contents branded by -The CentOS Project contain either The CentOS Trademark, The CentOS -Logo or The CentOS Symbol. Content branded by The CentOS Project -cannot be redistributed without previous conversation with The CentOS -Project. However, you can study and modify both content branded by -The CentOS Project and content not branded at all in the sake of -proposing improvements to The CentOS Project corporate visual -identity. -

-

If you are using the CentOS Artwork Repository for producing your own -corporate visual identity, you should remove all The CentOS Trademarks -from your contents and rename the repository to something other than -CentOS Artwork Repository. -

-

The CentOS Artwork Repository organizes files in a very specific way -to implement The CentOS Project corporate visual identity. This very -specific organization of files is part of centos-art.sh -script, a bash script that automates most of the frequent tasks inside -the repository. -

- - -

1.3.1 The centos-art.sh script

- -

The centos-art.sh script and the organization of files it -needs to work are not in the public domain; they are copyrighted and -there are restrictions on their distribution, but these restrictions -are designed to permit everything that a good cooperating citizen -would want to do. What is not allowed is to try to prevent others -from further sharing any version of this program that they might get -from you. -

-

Specifically, we want to make sure that you have the right to give -away copies of centos-art.sh script, that you receive source -code or else can get it if you want it, that you can change this -program or use pieces of it in new free programs, and that you know -you can do these things. -

-

To make sure that everyone has such rights, we have to forbid you to -deprive anyone else of these rights. For example, if you distribute -copies of the centos-art.sh script, you must give the -recipients all the rights that you have. You must make sure that -they, too, receive or can get the source code. And you must tell them -their rights. -

-

Also, for our own protection, we must make certain that everyone finds -out that there is no warranty for the centos-art.sh script. -If this program is modified by someone else and passed on, we want -their recipients to know that what they have is not what we -distributed, so that any problems introduced by others will not -reflect on our reputation. -

-

The precise conditions of the license for the centos-art.sh -script are found in the General Public Licenses that accompany it (see -`trunk/COPYING' file). This manual specifically is covered by -the GNU Free Documentation License. -

The `trunk/Identity/Themes/Motifs' directory exists to: -

- - - - - -

2.36.2 Description

- -

The artistic motif of theme is a graphic design component that -provides the visual style of themes, it is used as pattern to connect -all visual manifestations inside one unique theme. -

-

Artistic motifs are based on conceptual ideas. Conceptual ideas bring -the motivation, they are fuel for the engines of human imagination. -Good conceptual ideas may produce good motivation to produce almost -anything, and art works don't escape from it. -

-
-
`TreeFlower'
-

CentOS like trees, has roots, trunk, branches, leaves and flowers. Day -by day they work together in freedom, ruled by the laws of nature and -open standards, to show the beauty of its existence. -

-
`Modern'
-

Modern, squares and circles flowing up. -

-
- -

If you have new conceptual ideas for CentOS, then you can say that you -want to create a new artistic motif for CentOS. To create a new -artistic motif you need to create a directory under -`Identity/Themes/Motifs/' using a name coherent with your -conceptual idea. That name will be the name of your artistic motif. If -possible, when creating new conceptual ideas for CentOS, think about -what CentOS means for you, what does it makes you feel, take your -time, think deep, and share; you can improve the idea as time goes on. -

-

Once you have defined a name for your theme, you need to create the -motif structure of your theme. The motif structure is the basic -direcotry structure you'll use to work your ideas. Here is where you -organize your graphic design projects. -

-

To add a new motif structure to CentOS Artwork Repository, you need to -use the centos-art command line in the -`Identity/Themes/Motifs/' directory as described below: -

-
 
centos-art add --motif=ThemeName
-
-

The previous command will create the basic structure of themes for -you. The basic structure produced by centos-art command is -illustrated in the following figure: -

-
 
trunk/Identity/Themes/Motifs/$ThemeName/
-|-- Backgrounds
-|   |-- Img
-|   `-- Tpl
-|-- Info
-|   |-- Img
-|   `-- Tpl
-|-- Palettes
-`-- Screenshots

2.37 The `trunk/Identity/Themes/Motifs/Flame' Directory

- - - -

2.37.1 Goals

- -

This section describes the steps we followed to construct the -Flame artistic motif. This section may be useful for anyone -interested in reproducing the Flame artistic motif, or in -creating new artistic motifs for The CentOS Project corporate visual -identity (see section The `trunk/Identity' Directory). -

- - -

2.37.2 Description

- -

The Flame artistic motif was built using the flame filter of -Gimp 2.2 in CentOS 5.5. -

-

The flame filter of Gimp can produce stunning, randomly generated -fractal patterns. The flame filter of Gimp gives us a great oportunity -to reduce the time used to produce new artistic motifs, because of its -"randomly generated" nature. Once the artistic motif be created, it -is propagated through all visual manifestations of CentOS Project -corporate visual identity using the `centos-art.sh' script -(see section The `trunk/Scripts/Bash' Directory) inside the CentOS Artwork Repository. -

-

To set the time intervals between each new visual style production, we -could reuse the CentOS distribution major release schema. I.e., we -could produce a new visual style, every two years, based on a new -"randomly generated" flame pattern, and publish the whole corporate -visual identity (i.e., distribution stuff, promotion stuff, websites -stuff, etc.) with the new major release of CentOS distribution all -together at once. -

-

Producing a new visual style is not one day's task. Once we have -defined the artistic motif, we need to propagate it through all visual -manifestations of The CentOS Project corporate visual identity. When -we say that we could produce one new visual style every two years we -really mean: to work two years long in order to propagate a new visual -style to all visual manifestations of The CentOS Project corporate -visual identity. -

-

Obviously, in order to propagate one visual style to all different -visual manifestations of The CentOS Project corporate visual identity, -we need first to know which the visual manifestations are. To define -which visual manifestations are inside The CentOS Project corporate -visual identity is one of the goals the CentOS Artwork Repository and -this documentation manual are both aimed to satisfy. -

-

Once we define which the visual manifestation are, it is possible to -define how to produce them, and this way, organize the automation -process. Such automation process is one of the goals of -`centos-art.sh' script. -

-

With the combination of both CentOS Artwork Repository and -`centos-art.sh' scripts we define work lines where translators, -programmers, and graphic designers work together to distribute and -reduce the amount of time employed to produce The CentOS Project -monolithic corporate identity. -

-

From a monolithic corporate visual identity point of view, notice that -we are producing a new visual style for the same theme (i.e., -Flame). It would be another flame design but still a flame -design. This idea is very important to be aware of, because we are -somehow "refreshing" the theme, not changing it at all. -

-

This way, as we are "refreshing" the theme, we still keep oursleves -inside the monolithic conception we are trying to be attached to -(i.e., one unique name, and one unique visual style for all visual -manifestations). -

-

Producing artistic motifs is a creative process that may consume long -time, specially for people without experienced knowledge on graphic -design land. Using "randomly generated" conception to produce -artistic motifs could be, practically, a way for anyone to follow in -order to produce maintainable artistic motifs in few steps. -

-

Due to the "randomly generated" nature of Flame filter, we find that -Flame pattern is not always the same when we use Flame -filter interface. -

-

Using the same pattern design for each visual manifestation is -essential in order to maintain the visual connection among all visual -manifestations inside the same theme. Occasionally, we may introduce -pattern variations in opacity, size, or even position but never change -the pattern design itself, nor the color information used by images -considered part of the same theme. -

-
Important

Important

-When we design background images, which are considered part of the -same theme, it is essential to use the same design pattern always. -This is what makes theme images to be visually connected among -themeselves, and so, the reason we use to define the word "theme" -as: a set of images visually connected among themeselves. -

- -

In order for us to reproduce the same flame pattern always, -Flame filter interface provides the `Save' and `Open' -options. The `Save' option brings up a file save dialog that -allows you to save the current Flame settings for the plug-in, so that -you can recreate them later. The `Open' option brings up a file -selector that allows you to open a previously saved Flame settings -file. -

-

The Flame settings we used in our example are saved in the file: -

-
trunk/Identity/Themes/Motifs/Flame/Backgrounds/Xcf/800x600.xcf-flame.def
-
- - -

2.37.3 Construction

- - - -

2.37.3.1 Step 1: Set image size

- -

Create an empty image and fill the `Background' layer with black -(000000) color. Image dimensions depend on the final -destination you plan to use the image for. For the sake of our -construction example we used an image of 640x480 pixels and 300 pixels -per inch (ppi). -

- - -

2.37.3.2 Step 2: Add base color and pattern information

- -

Create a new layer named `Base', place it over `Background' -layer and fill it with the base color (7800ff) you want to have -your background image set in. Add a mask to `Base' layer using -radial gradient and blur it. You may need to repeat this step more -than once in order to achieve a confortable black radial degradation -on the right side of your design. -

-

Duplicate `Base' layer and name it `Paper'. Place -`Paper' layer over `Base' layer. Remove content of -`Paper' layer and fill it with `Paper (100x100)' pattern. -Once you've done with black radial degradation, reduce the -`Paper' layer opacity to 20%. -

-

Notice that when we duplicate one layer, the mask information related -to layer is preserved from previous to next layer. This saves us some -of the time required to produce different layers with the same mask -information on them. -

-

Duplicate `Paper' layer and rename it `Stripes'. Remove -paper pattern from `Stripes' layer. Fill `Stripes' layer -with `Stripes (48x48)' pattern and reduce the `Stripes' -layer opacity to 15%. -

- - -

2.37.3.3 Step 3: Add flame motif

- -

Create a new layer named `Flame'. Set the foreground -(003cff) and background (0084ff) colors to the gradient -you want to build the flame motif. -

-

To build flame motif, use the flame filter (`Filters > Render > -Nature > Flame...') on `Flame' layer. We used a layer mask, with -a radial gradient on it to control the boundaries of flame motif on -`Flame' layer. -

-

Duplicate `Flame' layer and rename it `Flame Blur'. Place `Flame -Blur' below `Flame' layer. Apply Gussian blur filter -(`Filters > Blur > Gussian Blur...') until reaching the desiered -effect. -

-

The opacity value, in `Flame' layers, may vary from one image to -another based on the place the image will be finally placed on. For -example, images used as desktop background have the `Flame' layer -opacity set at 100% but `Flame Blur' is set to 70%. However, you -may find that background images used in anaconda progress slides have -opacity reduced differently, in order to reduce brightness in a way -that texts could look clean and readable over it. -

- - -

2.37.3.4 Step 4: Add foreground color

- -

Create a new layer named `Color', place it on top of all visible -layers and fill it with plain color (4c005a). Reduce -`Color' layer opacity to 20%. You can use the `Color' layer -to control the right side color information you want to produce the -image for. -

-

Duplicate `Flame' layer and create a new layer named -`Color#1'. Place `Color#1' layer on top of layer named -`Color'. Remove the mask information from `Color#1' layer -and recreate a new one using an inverted alpha channel as reference. -Remove `Color#1' layer content and fill it back with plain black -(000000) color. Reduce `Color#1' opacity to 20%. In this -step we created a mask to protect the flame artistic motif from black -color, so when we decrement or increment the opacity of layer, the -flame artistic motif wouldn't be affected, just the environment -suround it. -

-

When you set color information, remember that the same artistic motif -needs to be indexed to 14 and 16 colors, in order to produce Grub and -Syslinux visual manifestations respectively. Using many different -colors in the artistic motif may reduce the possibility of your design -to fix all different situations in. Likewise, using more colors in -one design, and less colors in another design will reduce the -connectivity among your designs, since color information is relevant -to visual identity. -

-

When you propagate your artistic motif visual style to different -visual manifestations of CentOS Project corporate visual identity, it -is up to you to find out justice and compromise among all possible -variables you may face. -

2.39 The `trunk/Identity/Themes/Motifs/Modern/Backgrounds' Directory

- - - -

2.39.1 Goals

- - - - - -

2.39.2 Description

- -

Inside `Motifs' directory, the `Backgrounds/' directory is -used to create vectorial designs using Inkscape and background images -using Gimp. Later, you can export background images as `.png' and -load them in your vectorial design project using the import feautre of -Inkscape. -

-

You may need to repeat this technic for different screen resoluions. -In that case you need to create one file for each screen resolution -and do the appropriate linking inside .svg to .png files. For example -if you need to produce background images in 800x600 you need to create -the following file: -

-
 
xcf/800x600.xcf
-
-

to produce the background image: -

-
 
img/800x600-bg.png
-
-

which is loaded in: -

-
 
svg/800x600.svg
-
-

to produce the final background image: -

-
 
img/800x600.png         
-
-

The `img/800x600.png' background image is produced automatically -by means of rendering scripts. -

-

In other cases (e.g. Anaconda), it is possible that you need to make -some variations to one background image that don't want to appear on -regular background images of the same resolution. In this case you -need to create a new and specific background image for that art -component. For example, if you need to produce the background image -used by Anconda (800x600) art works you create the file: -

-
 
xcf/800x600-anaconda.xcf
-
-

to produce the background image: -

-
 
img/800x600-anaconda-bg.png
-
-

which is loaded in: -

-
 
svg/800x600-anaconda.svg
-
-

to produce the file: -

-
 
img/800x600-anaconda.png
-
-

The 800x600-anaconda.png file is used by all Anaconda art works -sharing a common 800x600 screen resolution (e.g., Header, Progress, -Splash, Firstboot, etc.). The Anaconda Prompt is indexed to 16 colors -and 640x480 pixels so you need to create a 640x480 background image -for it, and take the color limitation into account when designing it. -

-

Background images without artistic motif are generally used as based -to build the Background images that do contain the theme artistic -motif. -

-

Background images are linked (using the import feature of -Inkscape) inside almost all theme art works. This structure let you -make centralized changes on the visual identity and propagate them -quickly to other areas. -

-

In this structure you design background images for different screen -resolutions based on the theme artistic motif. -

-

You may create different artistic motifs propositions based -on the same conceptual idea. The conceptual idea is what defines a -theme. Artistic motifs are interpretations of that idea. -

-

Inside this directory artistic motifs are organized by name (e.g., -TreeFlower, Modern, etc.). -

-

Each artistic motif directory represents just one unique artistic -motif. -

-

The artistic motif is graphic design used as common pattern to connect -all visual manifestations inside one unique theme. The artistic motif -is based on a conceptual idea. Artistic motifs provide visual style -to themes. -

-

Designing artistic motifs is for anyone interested in creating -beautiful themes for CentOS. When building a theme for CentOS, the -first design you need to define is the artistic motif. -

- -

Inside CentOS Artwork Repository, theme visual styles (Motifs) and -theme visual structures (Models) are two different working lines. -When you design an artistic motif for CentOS you concentrate on its -visual style, and eventualy, use the centos-art command line -interface to render the visual style, you are currently producing, -against an already-made theme model in order to produce the final -result. Final images are stored under `Motifs/' directory using -the model name, and the model directory structure as reference. -

-

The artistic motif base structure is used by centos-art to -produce images automatically. This section describes each directory of -CentOS artistic motif base structure. -

- - -

2.39.3 Usage

- -

The `Backgrounds/' directory is probably the core component, -inside `Motifs/' directory structure. Inside `Backgrounds/' -directory you produce background images used by almost all theme -models (e.g., Distribution, Websites, Promotion, etc.). The -`Backgrounds/' directory can contain subdirectories to help you -organize the design process. -

Sometimes a command contains words that would be displayed -in a different style on their own (such as file names). In these -cases, they are considered to be part of the command, so the entire -phrase is displayed as a command. For example: -

-

Use the centos-art identity --render='path/to/dir' command -to produce contents inside the `trunk/Identity' directory -structure. -

-
- -
-
`file name'
-
-

File names, directory names, paths, and RPM package names are -represented this way. This style indicates that a particular file or -directory exists with that name on your system. Examples: -

-

The `init.sh' file in `trunk/Scripts/Bash/Cli/' directory is -the initialization script, written in Bash, used to automate most of -tasks in the repository. -

-

The centos-art command uses the `ImageMagick' RPM -package to convert images from PNG format to other formats. -

-
- -
-
key
-
-

A key on the keyboard is shown in this style. For example: -

-

To use TAB completion to list particular files in a directory, -type ls, then a character, and finally the Tab key. Your -terminal displays the list of files in the working directory that -begin with that character. -

-
- -
-
key-combination
-

A combination of keystrokes is represented in this way. For example: -

-

The Ctrl-Alt-Backspace key combination exits your graphical -session and returns you to the graphical login screen or the console. -

-
- -
-
computer output
-
-

Text in this style indicates text displayed to a shell prompt such as -error messages and responses to commands. For example: -

-

The ls command displays the contents of a directory. For example: -

-
Config                           manual_renameEntry.sh
-manual_copyEntry.sh              manual_restoreCrossReferences.sh
-manual_deleteCrossReferences.sh  manual_searchIndex.sh
-
-

The output returned in response to the command (in this case, the -contents of the directory) is shown in this style. -

-
- -

Additionally, we use several different strategies to draw your -attention to certain pieces of information. In order of urgency, these -items are marked as a note, tip, important, caution, or warning. For -example: -

-

2.46 The `trunk/Identity/Themes/Motifs/TreeFlower/Backgrounds' Directory

- - - -

2.46.1 Goals

- -

This section exists to orgnize backgrounds of TreeFlower -artistic motif. -

- - -

2.46.2 Description

- - - -

2.46.2.1 Desktop background

- -

Once you have defined the vectorial artistic motif design, use the -centos-art.sh script (as described in usage section below) -to produce the png version of it. With the png version of your -vectorial design do the following: -

-

Open the png version with GIMP. -

-

Save the png version as a project of GIMP inside -`trunk/Identity/Themes/Motifs/TreeFlower/Backgrounds/Xcf' -directory, using the same name of your vectorial design but with the -`.xcf' extension. -

-

Now use GIMP to improve your design. Here you may add one layer for -pattern, another for colors, and so on until you find yourself -confortable with your artwork. For example, the following layer -distribution (from bottom to top) was used to build revision 285 of -file `1360x768.xcf' using TreeFlower artistic motif at -revision 241. -

-
-
Layer 1: Background
-
-

The first thing we did with GIMP was to create a layer named -`Background' to store the artistic motif (File > Open as layer). -This layer is the lowest layer in the image. Later, we started to -create layers one upon another to change the artistic motif visual -style. -

-
-
Layer 2: Shadow#1
-
-

This layer is above `Background' and contains a linear gradient -from left (000000) to right (transparent) covering the whole image. -This layer masks the artistic motif to avoid the effect of linear -gradient. This layer is 100% of opacity. -

-
-
Layer 3: Shadow#2
-
-

This layer is above `Shadow#1' and contains a linear gradient -from left (000000) to right (transparent) covering just the 70% of the -whole image aproximatly. This layer doesn't mask the artistic motif -which make the left part of it fall into the dark of linear gradient. -This layer is 100% of opacity. -

-
-
Layer 4: Pattern (Paper)
-
-

This layer is above `Shadow#2' an contains the paper pattern -shipped with GIMP 2.2. This layer doesn't mask the artistic motif so -the pattern is applied over the whole image. This layer is set to 15% -of opacity. -

-
-
Layer 5: Pattern (Stripes)
-
-

This layer is above `Pattern (Paper)' and contains the stripes -used over the artistic motif. This layer do masks the artistic motif -so the stripes are only applied to it. This layer is set to 10% of -opacity. -

-
-
Layer 6: Shadow#3
-
-

This layer is above `Pattern (Stripes)' and contains a linear -gradient from right (6600ff) to left (transparent). This layer masks -the artistic motif so the linear gradient doesn't affect it. This -layer is set to 15% of opacity. -

-
-
Layer 7: Shadow#4
-
-

This layer is above `Shadow#3' and contains a -linear gradient from left (000000) to right (transparent). This layer -do masks the artistic motif so the linear gradient doesn't affect it. -This layer is set to 10% of opacity. -

-
-
Layer 8: Color#1
-
-

This layer is above `Shadow#4' and is filled with orange (ffae00) -color over the whole image. This layer is set to 10% of opacity. -

-
-
Layer 9: Color#2
-
-

This layer is above `Color#1' and is filled with -blue (010a88) color over the whole image. This layer is set to 10% of -opacity. -

-
-
- -
info

Note

There is no definite combination. To get the appropriate -visual design is a matter of constant testing and personal taste. -

- -

Finally, use `Save as copy ...' option to export the final -design. To export the final design use the same name of your vectorial -design plus `-final.png' extension. -

-

You can repeat these steps to create images for other screen -resolutions. -

- - -

2.46.2.2 Anaconda Prompt (syslinux) background

- -

When building syslinux backgrounds it is needed to take into account -that the final image is reduced to 16 colors. In desktop background -there is no color limitation but syslinux does have. The goal of this -section is achieving a final syslinux background as close as possible -to desktop backgrounds using 16 colors only. -

-

Another point to consider is the forground and background definition -used by syslinux. The syslinux documentation says that the color set -in position 0 is the background and color set in position 7 is the -forground. The final palette of color used by our background will -match that specification. For great contrast we'll use black as -background and white as forground. At this poing we have black -(000000) and white (ffffff) colors in our syslinux palette, which left -us with 14 colors to play with. -

-

Let's begin with `Xcf/640x300.xcf' layer distribution from bottom -to top: -

-
-
Layer 1: Background
-
-

This layer is the lowest layer in the image composition and contains -the artistic motif image rendered for the same resolution (i.e., -`Img/Png/640x300.png'). This layer is set to 100% of opacity. -

-
-
Layer 2: Pattern (Paper)
-
-

This layer is placed above `Background' layer and contains the -paper pattern shipped with GIMP 2.2. This layer doesn't mask the -artistic motif. This layer is set to 30% of opacity. -

-
-
Layer 3: Pattern (Stripes)
-
-

This layer is placed above `Pattern (Paper)' layer and contains -the stripes pattern shipped with GIMP 2.2. This layer does mask the -artistic motif in order to apply the stripes over it only. The -background is not affected by the stripes pattern just the artistic -motif. This layer is set to 20% of opacity. -

-
-
Layer 4: Shadow#1
-
-

This layer is placed above `Pattern (Stripes)' layer and fills -the entire layer area with violet (6600ff) color. This layer do mask -the artistic motif in order to applied the violet color to the -background area outside the artistic motif only. This layer is set to -15% of opacity. -

-
-
Layer 5: Color#1
-
-

This layer is above `Shadow#1' and is filled with orange (ffae00) -color to cover the whole image. This layer is set to 10% of opacity. -

-
-
Layer 6: Color#2
-
-

This layer is above `Color#1' and is filled with blue (010a88) -color to cover the whole image. This layer is set to 10% of opacity. -

-
-
Layer 7: Shadow#2
-
-

This layer is above `Color#1' and contains a linear gradient from -left (000000) to right (transparent) covering 70% of the image -approximately. -

-
-
- -

At this point we have the composition and should look like the desktop -backgrounds. Compared with desktop backgrounds there are some -differences in opacity. This is because in our testings the final -color information found with this composition produces an acceptable -16 color image. Of course this is something we haven't seen yet. -

-

To define the color information of our current coposition, save the -syslinux background composition we've done using `File > Save as -Copy ...' option in the following location: -

-
trunk/Identity/Themes/Motifs/TreeFlower/Backgrounds/Img/Png/640x300-final.png
-
-

Now, create the final png version of syslinux backgrounds using the -following command: -

-
centos-art render --entry=trunk/Identity/Themes/Motifs/TreeFlower/Distro/Anaconda/Prompt
-
-

This command will create syslinux-splash final images for all major -releases of CentOS distribution the repository has been configured to. -The important files here are `syslinux-splash.png', other -files may contain the wrong information because we haven't defined yet -the correct color information to use. -

-

Open one `syslinux-splash.png' file with GIMP and use the -`Image > Mode > Indexed' to reduce image colors up to 16 colors, -using the `Generate optimum palette' feature of GIMP. If the -image looks aceptable after reducing colors, use the `Palettes' -menu (Ctrl+P) of GIMP to import a new palette from file and name it -`CentOS-TreeFlower-Syslinux'. Once you've saved the palette, the -color information is stored at: -

-
~/.gimp-2.2/palettes/CentOS-TreeFlower-Syslinux.gpl
-
-

You need to edit `CentOS-TreeFlower-Syslinux.gpl' file in order -to set the appropriate order of colors. Remember black (000000) in -position 0, and white (ffffff) in position 7. Other positions are -irrelevant. When editing this file you may find that color reduction -did not set black and white colors to their respective values exactly. -Change that manually. For example, consider the following palette: -

-
GIMP Palette
-Name: CentOS-TreeFlower-Syslinux
-Columns: 16
-#
-  0   0   0	Background (black)
- 23  20  35	Untitled
- 34  25  48	Untitled
- 37  35  60	Untitled
- 47  36  68	Untitled
- 37  54  86	Untitled
- 60  48  90	Untitled
-255 255 255	Foreground (white)
- 66  54  99	Untitled
- 74  61  98	Untitled
- 49  78 126	Untitled
- 43  87 151	Untitled
- 92  89  95	Untitled
- 54 104 183	Untitled
-158 153 156	Untitled
-201 196 195	Untitled
-
-

Update the `Palettes' menu to get the new color positions from -the file you just edited and open the palette with double click. -

-

Update the `syslinux.gpl' file copying the following file: -

-
~/.gimp-2.2/palettes/CentOS-TreeFlower-Syslinux.gpl
-
-

to -

-
trunk/Identity/Themes/Motifs/TreeFlower/Colors/syslinux.gpl
-
-

With the `CentOS-TreeFlower-Syslinux' palette opened in the -`Palette Editor', open (Ctrl+O) the following file: -

-
trunk/Identity/Themes/Motifs/TreeFlower/Colors/syslinux.ppm
-
-

and replace its color information with that one in -`CentOS-TreeFlower-Syslinux' palette. When you are replacing -color information inside `syslilnux.ppm', remember to keep the -order of colors just as they are in the -`CentOS-TreeFlower-Palette' palette. -

-

The `syslinux.ppm' file is 16 pixels width and 1 pixel height, so -you probably need to zoom it a bit to set the color information in -their place when using the pen tool with the brush `Circle (01) -(1 x 1)'. -

-

Once you've updated the `syslinux.ppm' file, it is time to update -the following file: -

-
trunk/Identity/Themes/Motifs/TreeFlower/Colors/syslinux.hex
-
-

The `syslinux.hex' file contains the color information in -hexadecimal notation. The color information in hexadecimal notation -is required by ppmtolss16 command. The ppmtolss16 -command produces the final LSS16 image format that is used by syslinux -program inside CentOS distribution. -

-

The color information inside `syslinux.hex' must match the one in -`syslinux.ppm' and `syslinux.gpl'. For example, based on -`CentOS-TreeFlower-Syslinux' palette of colors above, consider -the following `syslinux.hex' file: -

-
#000000=0
-#171423=1
-#221930=2
-#25233c=3
-#2f2444=4
-#253656=5

-#ffffff=7
-#423663=8
-#4a3d62=9
-#314e7e=10
-#2b5797=11
-#5c595f=12

2.48 The `trunk/Locales' Directory

- -

The `trunk/Locales' directory exists to store the translation -messages used to produce content in different languages. -

-

Translation messages are organized using the directory structure of -the component being translated. For example, if we want to provide -translation messages for `trunk/Manuals/Filesystem', then the -`trunk/Locales/Manuals/Filesystem' directory needs to be created. -

-

Once the locale directory exists for the component we want to provide -translation messages for, it is necessary to create the translation -files where translation messages are. The translation files follows -the concepts of xml2po and GNU gettext tools. -

-

The basic translation process is as follow: first, translatable -strings are extracted from files and a portable object template (.pot) -is created or updated with the information. Using the portable object -template, a portable object (.po) is created or updated for translator -to locale the messages retrived. Finally, a machine object (.mo) is -created from portable object to sotore the translated messages. -

-

Inside the repository there are two ways to retrive translatable -strings from files. The first one is through xml2po command -and the second through xgettext command. The xml2po -is used to retrive translatable strings from XML files (e.g., Scalable -Vector Graphics, DocBook, etc.) and the xgettext command is -used to retrive translatable strings from shell scripts files (e.g., -the files that make the centos-art.sh command-line -interface). -

-

When translatable strings are retrived from XML files, using the -xml2po command, there is no need to create the machine -object as we do when translatable strings ar retrived from shell -files, using the xgettext command. The xml2po -produces a temporal machine object in order to create a translated XML -file. Once the translated XML file has been created the machine object -is no longer needed. On the other hand, the machine object produced by -the xgettext command is required by the system in order for -the show shell script localized messages. -

-

Another difference between xml2po and xgettext we -need to be aware of is the directory structure used to store machine -objects. In xml2po, the machine object is created in the -current working directory as `.xml2po.mo' and can be safetly -removed once the translated XML file has been created. In the case of -xgettext, the machine object needs to be stored in the -`$TEXTDOMAIN/$LOCALE/LL_MESSAGES/$TEXTDOMAIN.mo' file in order -for the system to interpret it and should not be removed since it is -the file that contain the translation messages themselves. -

-

Automation of localization tasks is achived through the locale -functionality of command-line interface. -

2.50 The `trunk/Locales/Identity/Brands' Directory

- - - -

2.50.1 Goals

- - - - - -

2.50.2 Description

- -

Translation files, inside `trunk/Translations/Identity/Brands' -translation entry, don't use default rendering translation -functionality, they use the following translation pre-rendering -configuration file instead: -

-
/home/centos/artwork/trunk/Translation/Identity/Brands/render.conf.sh
-
-

Inside `trunk/Translations/Identity/Brands' translation entry, -translation files are symbolic links pointing to the common template -translation structure, inside the translation template (`Tpl/') -directory. -

-

Inside `trunk/Translations/Identity/Brands' translation entry, -translation files are created using identity design templates as -reference. The translation pre-rendering script creates a translation -structure where the translation template (`Tpl/') directory -structure applies to each single design template available. -

-

For example, if the brands' translation template (`Tpl/') -directory has 30 translation files, and there are 20 design templates; -the brands' translation pre-rendering script creates a translation -structure of symbolic links where the 30 translation files apply the -20 design templates one by one, producing 600 translation symbolic -links as result. At this point, when rendering identity, the -centos-art script considers translation symbolic links as -translation files. -

-

Translation file names, inside brands' translation template -(`Tpl') directory have special meaning: -

- - -

2.50.2.1 Conventional file names

- -

Convenctional file names look like `blue.sed', `2c-a.sed', -etc. Replacement commands inside translation file are applied to -design templates and translation file names are used as final image -name. The image dimensions use the same dimensions that design -template has. -

- - -

2.50.2.2 Numeric file names

- -

Numeric file names look like `300.sed', `200.sed', etc. -Replacements commands inside translation files are applied to design -templates, and translation file names are used as final image name. -The final image is saved using an specific `width' defined by the -number part of the translation file name. The image `height' is -automatically scaled based on the previous `width' definition to -maintain the designing ratio. -

-

For example, if your design template has 400x200 pixels of dimension, -and you apply a translation file named `300.sed' to it, the final -image you get as result will have 300x100 pixels of dimension. The -same is true if you use higher numbers like `1024.sed', `2048.sed', -etc. In these cases you have bigger images proportionally. -

-

As we are using scalable vector graphics to design identity templates, -the image size you produce is not limitted in size. You can use one -design template produced in 400x200 pixels to produce larger or -shorter PNG images using numeric translation files as described -above. -

- - -

2.50.2.3 Translation markers

- -

Inside `trunk/Translations/Identity/Brands/', translation files -combine the following translation markers: -

-
-
`#000000'
-
-

Specify which color to use when rendering brand images. -

-
info

Note

As translation files inside -`trunk/Translations/Identity/Brands' are symbolic links that -point to template translation files, translation markers are defined -inside template translation files. -

-
-
- - - -

2.50.3 Usage

- -

To render brands' translation files, use the following command: -

-
centos-art render --translation=/home/centos/artwork/trunk/Translations/Identity/Brands
-

2.52 The `trunk/Locales/Identity/Fonts' Directory

- - - -

2.52.1 Goals

- -

This section exists to organize fonts translation files. -

- -

2.52.2 Description

- -

Translation files, inside `trunk/Translations/Fonts', have the -following structure: -

-
s!font-family:Denmark!font-family:DejaVu LGC Sans!
-s!font-weight:normal!font-weight:bold!
-s!font-style:normal!font-style:italic!
-
-

Inside `trunk/Translations/Fonts', there is one translation file -for each font preview image you want to produce. This way, we create -one translation file for each font-family we use somewhere inside -CentOS visual identity. -

-
Important

Important

Do not create translation files for -font-families not used somewhere inside CentOS visual identity. The -identity of font entry (see section The `trunk/Identity/Fonts' Directory) is used as -reference when someone needs to know which font-families are allowed -to use inside CentOS visual identity. -

- - - -

2.52.2.1 Translation Markers

- -

Inside `trunk/Translations/Identity/Fonts', translation files -combine the following translation markers: -

-
-
`font-family:Denmark'
-

Specify which font family to use when rendering font preview images. -

-
`font-weight:normal'
-

Specify which font weight to use when rendering font preview images. -

-
`font-style:normal'
-

Specify which font style to use when rendering font preview images. -

-
- - - -

2.52.3 Usage

- -

Inside `trunk/Translations/Fonts' you use your favorite text -editor to create translation files. Inside -`trunk/Translations/Fonts' there is not translation template -directory (`Tpl/'), nor translation rendering using -centos-art script. For example, to create the -`dejavu_lgc_sans-boldoblique.sed' translation file using -vim editor, type the following command: -

-
vim /home/centos/artwork/trunk/Translations/Fonts/dejavu_lgc_sans-boldoblique.sed

2.57 The `trunk/Locales/Identity/Themes/Distro/Anaconda/Progress' Directory

2.57.1 Goals

- - - - - -

2.57.2 Description

- -

Use the following command to produce translation files based: -

-
 
trunk/Translations/Identity/Themes/Distro/Anaconda/Progress
-`-- Tpl
-    |-- en
-    |   |-- 01-welcome.sed
-    |   |-- 02-donate.sed
-    |   `-- 03-yum.sed
-    `-- es
-        |-- 01-welcome.sed
-        |-- 02-donate.sed
-        `-- 03-yum.sed
-
-

In order to produce the slide images in PNG format we need to have the -translation files first. So we use the following commands to create -translation files for CentOS 3, 4, and 5 major releases: -

-
 
centos-art render --translation --filter='3,4,5'
-
-

The above commands will produce the following translation structure: -

-
 
trunk/Translations/Identity/Themes/Distro/Anaconda/Progress
-|-- 3
-|   |-- en
-|   |   |-- 01-welcome.sed
-|   |   |-- 02-donate.sed
-|   |   `-- 03-yum.sed
-|   `-- es
-|       |-- 01-welcome.sed
-|       |-- 02-donate.sed
-|       `-- 03-yum.sed
-|-- 4
-|   |-- en
-|   |   |-- 01-welcome.sed
-|   |   |-- 02-donate.sed
-|   |   `-- 03-yum.sed
-|   `-- es
-|       |-- 01-welcome.sed
-|       |-- 02-donate.sed
-|       `-- 03-yum.sed
-|-- 5
-|   |-- en
-|   |   |-- 01-welcome.sed
-|   |   |-- 02-donate.sed
-|   |   `-- 03-yum.sed
-|   `-- es
-|       |-- 01-welcome.sed
-|       |-- 02-donate.sed
-|       `-- 03-yum.sed
-`-- Tpl
-    |-- en
-    |   |-- 01-welcome.sed
-    |   |-- 02-donate.sed
-    |   `-- 03-yum.sed
-    `-- es
-        |-- 01-welcome.sed
-        |-- 02-donate.sed
-        `-- 03-yum.sed
-
-

At this point we have all the translation files we need to produce -Anaconda progress welcome, donate and yum slides images; in English -and Spanish languages; for CentOS 3, CentOS 4, and CentOS 5. That is, -a sum of 18 images around. -

-

Now, with translation files in place, let's move to -`trunk/Identity' structure and render them. -

- - - - -

2.57.3 Usage

- -

Translation rendering is described in `trunk/Translations' -documentation entry (-- Removed(pxref:trunk Translations) --). -

2.62 The `trunk/Scripts/Bash' Directory

- - - -

2.62.1 Goals

- -

The `trunk/Scripts/Bash' directory exists to organize the trunk -development line of `centos-art.sh' automation script. The -`centos-art.sh' script standardizes frequent tasks inside your -working copy of CentOS Artwork Repository. -

- - -

2.62.2 Description

- -

The best way to understand `centos-art.sh' automation script is -studying its source code. However, as start point, you may prefer to -read an introductory resume before diving into the source code -details. -

-

The `centos-art.sh' script is written in Bash. Most tasks, inside -`centos-art.sh' script, have been organized in many specific -functionalities that you can invoke from the centos-art -command-line interface. -

-

When you type the centos-art command in your terminal, the -operating system trys to execute that command. In order to execute the -command, the operating system needs to know where it is, so the -operating system uses the PATH environment variable to look for -that command location. If your system was prepared to use CentOS -Artwork Repository correctly (-- Removed(pxref:trunk Scripts Bash Functions -Verify) --), you should have a symbolic link inside `~/bin/' -directory that points to the `centos-art.sh' script file. As -`~/bin/' directory is, by default, inside PATH environment -variable, the execution of centos-art command runs the -`centos-art.sh' script. -

-

When `centos-art.sh' script is executed, the first it does is -executing the `trunk/Scripts/Bash/initEnvironment.sh' script to -initialize global variables (e.g., gettext variables) and -global function scripts. Global function scripts are located inside -`trunk/Scripts/Bash/Functions' directory and their file names -begin with `cli'. Global function scripts provide common -functionalities that can be used anywhere inside `centos-art.sh' -script execution environment. -

-

Once global variables and function scripts have been loaded, -`centos-art.sh' script executes the cli global function -from `cli.sh' function script to retrive command-line arguments -and define some default values that may be used later by specific -function scripts (-- Removed(pxref:trunk Scripts Bash Functions) --). -

-

As convenction, the `centos-art.sh' command-line arguments have -the following format: -

-
centos-art arg1 --arg2=val2 --arg3=val3
-
-

In the above example, `centos-art' is the command you use to -invoke `centos-art.sh' script. The `arg1' is required and -represents the functionality you want to perform (e.g., -`verify', `render', `locale', `manual', -etc.). The remaining arguments are modifiers to `arg1'. The -`--arg2' definition is required and represets, specifically, -the action inside the functionality you want to perform. The -`--arg3' and on, are optional. -

-

Once command-line arguments have been retrived, the -`centos-art.sh' script loads specific functionalities using the -`cli_getFunctions.sh' function script. Only one specific -functionality can be loaded at one script execution I.e., you run -centos-art.sh script to run just one functionality. -

Functionalities are implemented by means of actions. Once the -functionality has been initiazalized, actions initialization take -place for that functionality. Actions initialization model is very -similar to functions initialization model. But with the difference, -that actions are loaded inside function environment, and so, share -variables and functions defined inside function environment. -

2. Repository File System

- -

The CentOS Artwork Repsotiroy File System is the place where we -organize The CentOS Project Corporate Visual Identity. The CentOS -Artwork Repository uses directories to organize files and describe -conceptual idea about corporate identity. Such conceptual ideas are -explained in each directory related documentation entry. -

-

In this chapter you'll learn what each directory inside The CentOS -Artwork Repository is for and so, how you can make use of them. For -that purpose, the following list of directories is available for you -to explore: -

2.64 The `trunk/Scripts/Bash/Cli/Functions' Directory

- - - -

2.64.1 Goals

- -

The `trunk/Scripts/Bash/Functions' directory exists to organize -`centos-art.sh' specific functionalities. -

- - -

2.64.2 Description

- -

The specific functions of `centos-art.sh' script are designed -with "Software Toolbox" philosophy (see (coreutils.info)Toolbox introduction) in mind: each program "should do one -thing well". Inside `centos-art.sh' script, each specific -functionality is considered a program that should do one thing well. -Of course, if you find that they still don't do it, feel free to -improve them in order for them to do so. -

-

The specific functions of `centos-art.sh' script are organized -inside specific directories under `trunk/Scripts/Bash/Functions' -location. Each specific function directory should be named as the -function it represents, with the first letter in uppercase. For -example, if the function name is render, the specific function -directory for it would be `trunk/Scripts/Bash/Functions/Render'. -

-

To better understand how specific functions of `centos-art.sh' -script are designed, lets create one function which only goal is to -output different kind of greetings to your screen. -

-

When we create specific functions for `centos-art.sh' script it -is crucial to know what these functions will do exactly and if there -is any function that already does what we intend to do. If there is no -one, it is good time to create them then. Otherwise, if -functionalities already available don't do what you exactly expect, -contact their authors and work together to improve them. -

-
Info

Tip

Join CentOS developers mailing list -centos-art@centos.org to share your ideas. -

- -

It is also worth to know what global functions and variables do we -have available inside `centos-art.sh' script, so advantage can be -taken from them. Global variables are defined inside global function -scripts. Global functions scripts are stored immediatly under -`trunk/Scripts/Bash/Functions' directory, in files begining with -`cli' prefix. -

-

OK, let's begin with our functionality example. -

-

What function name do we use? Well, lets use greet. Note that -`hello' word is not a verb; but an expression, a kind of -greeting, an interjection specifically. In contrast, `greet' is a -verb and describes what we do when we say `Hello!', `Hi!', -and similar expressions. -

-

So far, we've gathered the following function information: -

-
Name: greet
-Path: trunk/Scripts/Bash/Functions/Greet
-File: trunk/Scripts/Bash/Functions/Greet/greet.sh
-
-

The `greet.sh' function script is the first file -`centos-art.sh' script loads when the `greet' functionality -is called using commands like `centos-art greet --hello='World''. -The `greet.sh' function script contains the greet function -definition. -

-

Inside `centos-art.sh' script, as convenction, each function -script has one top commentary, followed by one blank line, and then -one function defintion below it only. -

-

Inside `centos-art.sh' script functions, top commentaries have -the following components: the functionality description, one-line for -copyright note with your personal information, the license under -which the function source code is released --the `centos-art.sh' -script is released as GPL, so do all its functions--, the $Id$ -keyword of Subversion is later expanded by svn propset -command. -

-

In our greet function example, top commentary for -`greet.sh' function script would look like the following: -

-
#!/bin/bash
-#
-# greet.sh -- This function outputs different kind of greetings to
-# your screen. Use this function to understand how centos-art.sh
-# script specific functionalities work.

-# USA.
-# 
-# ----------------------------------------------------------------------
-# $Id$
-# ----------------------------------------------------------------------
-
-

After top commentary, separated by one blank line, the greet -function definition would look like the following: -

-
function greet {
-
-    # Define global variables.
-
-    # Define command-line interface.
-    greet_getActions
-
-}
-
-

The first definition inside greet function, are global -variables that will be available along greet function execution -environment. This time we didn't use global variable definitions for -greet function execution environment, so we left that section -empty. -

-

Later, we call greet_getActions function to define the -command-line interface of greet functionality. The command-line -interface of greet functionality defines what and how actions -are performed, based on arguments combination passed to -`centos-art.sh' script. -

-
function greet_getActions {
-
-    case "$ACTIONNAM" in
-
-        --hello )
-            greet_doHello
-            ;;
-
-        --bye )
-            greet_doBye
-            ;;
-
-        * )
-            cli_printMessage "`gettext "The option provided is not valid."`"
-            cli_printMessage "$(caller)" 'AsToKnowMoreLine'
-
-    esac
-
-}
-
-

The ACTIONNAM global variable is defined in `cli.sh' -function script and contains the value passed before the equal sign -(i.e., `=') in the second command-line argument of -`centos-art.sh' script. For example, if the second command-line -argument is `--hello='World'', the value of ACTIONNAM -variable would be `--hello'. Using this configuration let us -deside which action to perform based on the action name passed to -`centos-art.sh' script as second argument. -

-

The greet function definition makes available two valid -greetings through `--hello' and `--bye' options. If no -one of them is provided as second command-line argument, the `*' -case is evaluated instead. -

-

The `*' case and its two lines further on should always be -present in `_getActions.sh' function scripts, no matter what -specific functionality you are creating. This convenction helps the -user to find out documentation about current functionality in use, -when no valid action is provided. -

-

The greet_doHello and greet_doBye function definitions -are the core of greet specific functionality. In such function -definitions we set what our greet function really does: to -output different kinds of greetings. -

-
function greet_doHello {
-
-    cli_printMessage "`gettext "Hello"` $ACTIONVAL"
-
-}
-
-

The greet_doHello function definition is stored in -`greet_doHello.sh' function script. -

-
function greet_doBye {
-
-    cli_printMessage "`gettext "Goodbye"` $ACTIONVAL"
-
-}
-
-

The greet_doBye function definition is stored in the -`greet_doBye.sh' function script. -

-

Both `greet_doHello.sh' and `greet_doBye.sh' function -scripts are stored inside greet function directory path (i.e. -`trunk/Scripts/Bash/Functions/Greet'). -

-

The ACTIONVAL global variable is defined in `cli.sh' -function script and contains the value passed after the equal sign -(i.e., `=') in the second command-line argument of -`centos-art.sh' script. For example, if the second command-line -argument is `--hello='World'', the value of ACTIONVAL -variable would be `World' without quotes. -

-

Let's see how greet specific functionality files are organzied -under greet function directory. To see file organization we use -the tree command: -

-
trunk/Scripts/Bash/Functions/Greet
-|-- greet_doBye.sh
-|-- greet_doHello.sh
-|-- greet_getActions.sh
-`-- greet.sh
-
-

To try the greet specific functionality we've just created, -pass the function name (i.e., `greet') as first argument to -`centos-art.sh' script, and any of the valid options as second -argument. Some examples are illustrated below: -

-
[centos@projects ~]$ centos-art greet --hello='World'
-Hello World
-[centos@projects ~]$ centos-art greet --bye='World'
-Goodbye World
-[centos@projects ~]$ 
-
-

The word `World' in the examples above can be anything. In fact, -change it to have a little fun. -

-

Now that we have a specific function that works as we expect, it is -time to document it. To document greet specific functionality, -we use its directory path and the manual functionality -(-- Removed(pxref:trunk Scripts Bash Functions Manual) --) of `centos-art.sh' -script, just as the following command illustrates: -

-
centos-art manual --edit=trunk/Scripts/Bash/Functions/Greet
-
-

To have a well documented function helps user to understand how your -function really works, and how it should be used. When no valid -action is passed to a function, the `centos-art.sh' script uses -the function documentation entry as vehicle to communicate which the -valid functions are. When no documentation entry exists for a -function, the `centos-art.sh' script informs that no -documentation entry exists for such function and requests user to -create it right at that time. -

-

Now that we have documented our function, it is time to translate its -output messages to different languages. To translate specific -functionality output messages to different languages we use the -locale functionality (-- Removed(pxref:trunk Scripts Bash Functions -Locale) --) of `centos-art.sh' script, just as the following command -illustrates: -

-
centos-art locale --edit
-
-
Warning

Warning

To translate output messages in different languages, -your system locale information --as in LANG environment -variable-- must be set to that locale you want to produce translated -messages for. For example, if you want to produce translated messages -for Spanish language, your system locale information must be set to -`es_ES.UTF-8', or similar, first. -

- -

Well, it seems that our example is rather complete by now. -

-

In greet function example we've described so far, we only use -cli_printMessage global function in action specific function -definitions in order to print messages, but more interesting things -can be achieved inside action specific function definitions. For -example, if you pass a directory path as action value in second -argument, you could retrive a list of files from therein, and process -them. If the list of files turns too long or you just want to control -which files to process, you could add the third argument in the form -`--filter='regex'' and reduce the amount of files to process -using a regular expression pattern. -

-

The greet function described in this section may serve you as -an introduction to understand how specific functionalities work inside -`centos-art.sh' script. With some of luck this introduction will -also serve you as motivation to create your own `centos-art.sh' -script specific functionalities. -

-

By the way, the greet functionality doesn't exist inside -`centos-art.sh' script yet. Would you like to create it? -

- - -

2.64.3 Usage

- - - -

2.64.3.1 Global variables

- -

The following global variables of `centos-art.sh' script, are -available for you to use inside specific functions: -

-
-
Variable: TEXTDOMAIN - -
-

Default domain used to retrieve translated messages. This value is set -in `initFunctions.sh' and shouldn't be changed. -

- -
-
Variable: TEXTDOMAINDIR - -
-

Default directory used to retrieve translated messages. This value is -set in `initFunctions.sh' and shouldn't be changed. -

- -
-
Variable: FUNCNAM - -
-

Define function name. -

-

Function names associate sets of actions. There is one set of actions -for each unique function name inside `centos-art.sh' script. -

-

Dunction names are passed as first argument in `centos-art.sh' -command-line interface. For example, in the command `centos-art -render --entry=path/to/dir --filter=regex', the ACTION passed to -`centos-art.sh' script is `render'. -

-

When first argument is not provided, the `centos-art.sh' script -immediatly ends its execution. -

- -
-
Variable: FUNCDIR - -
-
- -
-
Variable: FUNCDIRNAME - -
-
- -
-
Variable: FUNCSCRIPT - -
-
- -
-
Variable: FUNCCONFIG - -
-
- -
-
Variable: ACTIONNAM - -
-

Define action name. -

-

Each action name identifies an specific action to perform, inside an -specific function. -

-

Action name names aare passed as second argument in -`centos-art.sh' command-line interface. For example, in the -command `centos-art render --entry=path/to/dir --filter=regex', -the ACTIONNAM passed to `centos-art.sh' script is -`--entry'. -

-

When second argument is not provided, the `centos-art.sh' script -immediatly ends its execution. -

- -
-
Variable: ACTIONVAL - -
-

Define action value. -

-

Action values are associated to just one action name. Action values -contain the working copy entry over which its associated action will be -performed in. Working copy entries can be files or directories inside -the working copy. -

- -
-
Variable: REGEX - -
-

Define regular expression used as pattern to build the list of files -to process. -

-

By default, REGEX variable is set to .+ to match all -files. -

-

Functions that need to build a list of files to process use the option -`--filter' to redefine REGEX variable default value, and -so, control the amount of files to process. -

- -
-
Variable: ARGUMENTS - -
-

Define optional arguments. -

-

Optional arguments, inside `centos-art.sh' script, are considered -as all command-line arguments passed to `centos-art.sh' script, -from third argument position on. For example, in the command -`centos-art render --entry=path/to/dir --filter=regex' , the -optional arguments are from `--filter=regex' argument on. -

-

Optional arguments are parsed using getopt command through -the following base construction: -

-
# Define short options we want to support.
-local ARGSS=""
-
-# Define long options we want to support.
-local ARGSL="filter:,to:"
-
-# Parse arguments using getopt(1) command parser.
-cli_doParseArguments
-
-# Reset positional parameters using output from (getopt) argument
-# parser.
-eval set -- "$ARGUMENTS"
-
-# Define action to take for each option passed.
-while true; do
-    case "$1" in
-        --filter )
-            REGEX="$2" 
-            shift 2
-            ;;
-        --to )
-            TARGET="$2" 
-            shift 2
-            ;;
-        * )
-            break
-    esac
-done
-
-

Optional arguments provide support to command options inside -`centos-art.sh' script. For instance, consider the Subversion -(svn) command, where there are many options (e.g., -`copy', `delete', `move', etc), and inside each -option there are several modifiers (e.g., `--revision', -`--message', `--username', etc.) that can be combined one -another in their short or long variants. -

-

The ARGUMENTS variable is used to store arguments passed from -command-line for later use inside `centos-art.sh' script. Storing -arguments is specially useful when we want to run a command with some -specific options from them. Consider the following command: -

-
centos-art path --copy=SOURCE --to=TARGET --message="The commit message goes here." --username='johndoe'
-
-

In the above command, the `--message', and `--username' -options are specific to svn copy command. In such cases, -options are not interpreted by `centos-art.sh' script itself. -Instead, the `centos-art.sh' script uses getopt to -retrive them and store them in the ARGUMENTS variable for later -use, as described in the following command: -

-
# Build subversion command to duplicate locations inside the
-# workstation.
-eval svn copy $SOURCE $TARGET --quiet $ARGUMENTS
-
-

When getopt parses ARGUMENTS, we may use short options -(e.g., `-m') or long options (e.g., `--message'). When -we use short options, arguments are separated by one space from the -option (e.g., `-m 'This is a commit message.''). When we use -long options arguments are separated by an equal sign (`=') -(e.g., `--message='This is a commit message''). -

-

In order for getopt to parse ARGUMENTS correctly, it -is required to provide the short and long definition of options that -will be passed or at least supported by the command performing the -final action the function script exists for. -

-

As convenction, inside `centos-art.sh' script, short option -definitions are set in the ARGSS variable; and long option -definitions are set in the ARGSL variable. -

-

When you define short and long options, it may be needed to define -which of these option arguments are required and which not. To define -an option argument as required, you need to set one colon `:' -after the option definition (e.g., `-o m: -l message:'). On -the other hand, to define an option argument as not required, you need -to set two colons `::' after the option definition (e.g., -`-o m:: -l message::'). -

- -
-
Variable: EDITOR - -
-

Default text editor. -

-

The `centos-art.sh' script uses default text EDITOR to edit -pre-commit subversion messages, translation files, configuration -files, script files, and similar text-based files. -

-

If EDITOR environment variable is not set, `centos-art.sh' -script uses `/usr/bin/vim' as default text editor. Otherwise, the -following values are recognized by `centos-art.sh' script: -

-
    -
  • `/usr/bin/vim' -
  • `/usr/bin/emacs' -
  • `/usr/bin/nano' -
- -

If no one of these values is set in EDITOR environment variable, -`centos-art.sh' uses `/usr/bin/vim' text editor by default. -

- - - -

2.64.3.2 Global functions

- -

Function scripts stored directly under -`trunk/Scripts/Bash/Functions/' directory are used to define -global functions. Global functions can be used inside action specific -functionalities and or even be reused inside themselves. This section -provides introductory information to global functions you can use -inside `centos-art.sh' script. -

-
-
Function: cli_checkActionArguments - -
-

Validate action value (ACTIONVAL) variable. -

-

The action value variable can take one of the following values: -

-
    -
  1. Path to one directory inside the local working copy, -
  2. Path to one file inside the local working copy, -
- -

If another value different from that specified above is passed to -action value variable, the `centos-art.sh' script prints an error -message and ends script execution. -

- -
-
Function: cli_checkFiles FILE [TYPE] - -
-

Verify file existence. -

-

cli_checkFiles receives a FILE absolute path and performs -file verification as specified in TYPE. When TYPE is not -specified, cli_checkFiles verifies FILE existence, no -matter what kind of file it be. If TYPE is specified, use one -of the following values: -

-
-
`d'
-
`directory'
-

Ends script execution if FILE is not a directory. -

-

When you verify directories with cli_checkFiles, if directory doesn't -exist, `centos-art.sh' script asks you for confirmation in order -to create that directory. If you answer positively, -`centos-art.sh' script creates that directory and continues -script flows normally. Otherwise, if you answer negatively, -`centos-art.sh' ends script execution with an error and -documentation message. -

-
-
`f'
-
`regular-file'
-

Ends script execution if FILE is not a regular file. -

-
`h'
-
`symbolic-link'
-

Ends script execution if FILE is not a symbolic link. -

-
`x'
-
`execution'
-

Ends script execution if FILE is not executable. -

-
`fh'
-

Ends script execution if FILE is neither a regular file nor a -symbolic link. -

-
`fd'
-

Ends script execution if FILE is neither a regular file nor a -directory. -

-
`isInWorkingCopy'
-

Ends script execution if FILE is not inside the working copy. -

-
- -

As default behaviour, if FILE passes all verifications, -`centos-art.sh' script continues with its normal flow. -

- -
-
Function: cli_commitRepoChanges [LOCATION] - -
-

Syncronize changes between repository and working copy. -

-

The cli_commitRepoChanges function brings changes from the -central repository down to the working copy--using svn -update--, checks the working copy changes--using svn -status command--, prints status report--using both svn -update and svn status commands output, and finally, commits -recent changes from the working copy up to the repository--using -svn commit command--. -

-

Previous to commit the working copy changes up to the central -repository, the cli_commitRepoChanges function asks you to -verify changes--using svn diff command--, and later, -another confirmation question is shown to be sure you really want to -commit changes up to central repository. -

-

If LOCATION argument is not specified, the value of -ACTIONVAL variable is used as reference instead. -

-
-
----------------------------------------------------------------------

-
-

Figure 2.3: The cli_commitRepoChanges function output. - -

-

Call the cli_commitRepoChanges function before or/and after -calling functions that modify files or directories inside the working -copy as you may need to. -

- -
-
Function: cli_doParseArguments - -
-

Redefine arguments (ARGUMENTS) global variable using -getopt command output. For more information about how to use -cli_doParseArguments function, see ARGUMENTS variable -description above. -

- -
-
Function: cli_doParseArgumentsReDef $@ - -
-

Initialize/reset arguments (ARGUMENTS) global variable using -positional parameters variable ($@) as reference. -

-

When we work inside function definitions, positional parameters are -reset to the last function definition positional parameters. If you -need to redefine positional parameters from one specific function, you -need to call cli_doParseArgumentsReDef with the positional -parameters variable ($@), set as first argument, to that -specific function you want to redefine positional parameters at. -

- -
-
Function: cli_getArguments - -
-

Initialize function name (FUNCNAM), action name -(ACTIONNAM), and action value (ACTIONVAL) global -variables, using positional parameters passed in $@ variable. -

-

The cli_getArguments function is called from cli.sh -function script, using cli function positional parameters -(i.e., the positional parameters passed as arguments in the -command-line) as first function argument. -

-

Once command-line positional parameters are accesible to -`centos-art.sh' script execution evironment, -cli_getArguments uses regular expression to retrive -action variables from first and second argument. The first argument -defines the value used as function name (FUNCNAM), and the -second argument defines both values used as action name -(ACTIONNAM) and action value (ACTIONVAL), respectively. -

-

The first argument is a word in lower case. This word specifies the -name of the functionality you want to use (e.g., `render' to -render images, `manual' to work on documentation, and so on.) -

-

The second argument has a long option style (e.g., -`--option=value'). The `--option' represents the action name -(ACTIONNAM), and the characters inbetween the equal sign -(`=') and the first space character, are considered as the action -value (ACTIONVAL). In order to provide action values with space -characters inbetween you need to enclose action value with quotes like -in `--option='This is long value with spaces inbetween''. -Generally, action values are used to specify paths over which the -action name acts on. -

-

Once action related variables (i.e., FUNCNAM, ACTIONNAM, -and ACTIONVAL) are defined and validated, -cli_getArguments shifts the positional arguments to remove the -first two arguments passed (i.e., those used to retrive action related -variables) and redefine the arguments (ARGUMENTS) global -variable with the new positional parameters information. -

- -
-
Function: cli_getFunctions - -
-

Initialize funtionalities supported by `centos-art.sh' script. -

-

Functionalities supported by `centos-art.sh' script are organized -in functionality directories under -`trunk/Scripts/Bash/Functions/' directory. Each functionality -directory stores function scripts to the functionality such directory -was created for. Function scripts contain function definitions. -Function definitions contain several commands focused on achieving one -specific task only (i.e., the one such functionality was created for). -

-

In order for `centos-art.sh' script to recognize a functionality, -such functionality needs to be stored under -`trunk/Scripts/Bash/Functions/' in a directory written -capitalized (i.e., the whole name is written in lowercase except the -first character which is in uppercase). The directory where one -specific functionality is stored is known as the `functionality -directory'. -

-

Inside each functionality directory, the functionalty itself is -implemented through function scripts. Function scripts are organized -in files independently one another and written in `camelCase' -format with the function name as prefix. Separation between prefix -and description is done using underscore (`_') character. -

-

In order for `centos-art.sh' script to load functionalities -correctly, function definition inside function scripts should be set -using the `function' reserved word, just as in the following -example: -

-
function prefix_doSomething {
-
-    # Do something here...
-
-}
-
-

The above function definition is just a convenction we use, in order -to make identification of function names easier read and automate by -`centos-art.sh' script initialization commands, once -`centos-art.sh' script determines which functionality directory -to use. Specifically, in order to initialize and export functions, -`centos-art.sh' script executes all function scripts inside the -functionality directory, and later grep on them using a -regular expression pattern, where the `function' reserved word is -used as reference to retrive the function names and export them to -`centos-art.sh' script execution environment, and so, make -function definitions --from function scripts inside the functionality -directory-- available for further calls. -

-

If the functionality specified in the command-line first argument -doesn't have a functionality directory, `centos-art.sh' script -considers the functionality provided in the command-line as invalid -functionality and immediatly stops script execution with an error -message. -

-

In order to keep visual consistency among function scripts, please -consider using the following function script design model as template -for your own function scripts: -

-
#!/bin/bash
-#
-# prefix_doSomething.sh -- This function illustrates function scripts
-# design model you can use to create your own function scripts inside
-# centos-art.sh script.

-function prefix_doSomething {
-
-    # Do something here...
-
-}
-
- -
-
Function: cli_getCountryCodes [FILTER] - -
-

Output country codes supported by `centos-art.sh' script. -

-

The cli_getCountryCodes function outputs a list with country -codes as defined in ISO3166 standard. When FILTER is provided, -cli_getCountryCodes outputs country codes that match -FILTER regular expression pattern. -

- -
-
Function: cli_getCountryName [FILTER] - -
-

Outputs country name supported by `centos-art.sh' script. -

-

The cli_getCountryName function reads one language locale code -in the format LL_CC and outputs the name of its related country as in -ISO3166. If filter is specified, cli_getCountryName returns the -country name that matches the locale code specified in FILTER, -exactly. -

- -
-
Function: cli_getCurrentLocale - -
-

Output current locale used by `centos-art.sh' script. -

-

The cli_getCurrentLocale function uses LANG environment -variable to build a locale pattern that is later applied to -cli_getLocales function output in order to return the current -locale that `centos-art.sh' script works with. -

-

The current locale information, returned by -cli_getCurrentLocale, is output from more specific to less -specific. For example, if `en_GB' locale exists in -cli_getLocales function output, the `en_GB' locale would -take precedence before `en' locale. -

-

Locale precedence selection is quite important in order to define the -locale type we use for message translations. For example, if -`en_GB' is used, we are also saying that the common language -specification for English language (i.e., `en') is no longer -used. Instead, we are using English non-common country-specific -language specifications like `en_AU', `en_BW', `en_GB', -`en_US', etc., for message translations. -

-

Use cli_getCurrentLocale function to know what current locale -information to use inside `centos-art.sh' script. -

- -
-
Function: cli_getFilesList [LOCATION] - -
-

Output list of files to process. -

-

The cli_getFilesList function uses LOCATION variable as -source location to build a list of files just as specified by regular -expression (REGEX) global variable. Essentially, what the -cli_getFilesList function does is using find command -to look for files in the location (LOCATION) just as posix-egrep -regular expression (REGEX) specifies. -

-

If LOCATION is not specified when cli_getFilesList -function is called, the action value (ACTIONVAL) global variable -is used as location value instead. -

-

By default, if the regular expression (REGEX) global variable is -not redefined after its first definition in the cli function, -all files that match default regular expression value (i.e., -`.+') will be added to the list of files to process. Otherwise, -if you redefine the regular expression global variable after its first -definition in the cli function and before calling -cli_getFilesList function, the last value you specifed is used -instead. -

-

When you need to customize the regular expression (REGEX) global -variable value inside a function, do not redefine the global variable -(at least you be absolutly convinced you need to). Instead, set the -regular expression global variable as `local' to the function you -need a customized regular expression value for. If we don't redefine -the regular expression global variable as local to the function, or -use another name for the regular expression variable (which is not -very convenient in order to keep the amount of names to remember low), -you may experiment undesired concantenation issues that make your -regular expression to be something different from that you expect them -to be, specially if the function where you are doing the variable -redefinition is called several times during the same script execution. -

-

As result, the cli_getFilesList re-defines the value of -FILES variable with the list of files the find command -returned. As example, consider the following construction: -

-
function prefix_doSomething {
-
-    # Initialize the list of files to process.
-    local FILES=''
-
-    # Initialize location.
-    local LOCATION=/home/centos/artwork/trunk/Identity/Themes/Models/Default
-
-    # Re-define regular expression to match scalable vector graphic
-    # files only. Note how we use the global value of REGEX to build a
-    # new local REGEX value here.
-    local REGEX="${REGEX}.*\.(svgz|svg)"
-
-    # Redefine list of files to process.
-    cli_getFilesList $LOCATION
-
-    # Process list of files.
-    for FILE in $FILES;do
-        cli_printMessages "$FILE" 'AsResponseLine'
-        # Do something else here on...
-    done
-
-}
-
-
- -
-
Function: cli_getLangCodes [FILTER] - -
-

Outputs language codes supported by `centos-art.sh' script. -

-

cli_getLangCodes function outputs a list of language codes as -defined in ISO639 standard. When FILTER is provided, -cli_getLangCodes outputs language codes that match FILTER -regular expression pattern. -

- -
-
Function: cli_getLangName [FILTER] - -
-

Outputs language names supported by `centos-art.sh' script. -

-

cli_getLangName function reads one language locale code in the -format LL_CC and outputs the language related name as in ISO639. If -filter is specified, cli_getLangName returns the language name -that matches the locale code specified in FILTER, exactly. -

- -
-
Function: cli_getLocales - -
-

Output locale codes supported by `centos-art.sh' script. -

-

Occasionally, you use cli_getLocales function to add locale -information in non-common country-specific language (`LL_CC') -format for those languages (e.g., `bn_IN', `pt_BR', etc.) -which locale differences cannot be solved using common language -specifications (`LL') into one unique common locale specification -(e.g., `bn', `pt', etc.). -

- -
-
Function: cli_getRepoName NAME TYPE - -
-

Sanitate file names. -

-

Inside `centos-art.sh' script, specific functionalities rely both -in cli_getRepoName and repository file system organization to -achieve their goals. Consider cli_getRepoName function as -central place to manage file name convenctions for other functions -inside `centos-art.sh' script. -

-
Important

Important

cli_getRepoName function doesn't verify file -or directory existence, for that purpose use cli_checkFiles -function instead. -

- -

The NAME variable contains the file name or directory name you -want to sanitate. -

-

The TYPE variable specifies what type of sanitation you want to -perform on NAME. The TYPE can be one of the following -values: -

-
-
`d'
-
`directory'
-

Sanitate directory NAMEs. -

-
`f'
-
`regular-file'
-

Sanitate regular file NAMEs. -

-
- -

Use cli_getRepoName function to sanitate file names and -directory names before their utilization. -

-

Use cli_getRepoName when you need to change file name -convenctions inside `centos-art.sh' script. -

-

When we change file name convenctions inside cli_getRepoName -what we are really changing is the way functions interpret repository -file system organization. Notice that when we change a file name -(e.g., a function name), it is necessary to update all files where -such file name is placed on. This may require a massive substitution -inside the repository, each time we change name convenctions in the -repository (-- Removed(pxref:trunk Scripts Bash Functions Path) --, for more -information). -

- -
-
Function: cli_getRepoStatus [LOCATION] - -
-

Request repository status. -

-

This function requests the status of a LOCATION inside the -working copy using the svn status command and returns the -first character in the output line, just as described in svn -help status. If LOCATION is not a regular file or a directory, -inside the working copy, the `centos-art.sh' script prints a -message and ends its execution. -

-

Use this function to perform verifications based a repository -LOCATION status. -

- -
-
Function: cli_getTemporalFile NAME - -
-

Output absolute path to temporal file NAME. -

-

The cli_getTemporalFile function uses `/tmp' directory as -source location to store temporal files, the `centos-art.sh' -script name, and a random identification string to let you run more -than one `centos-art.sh' script simultaneously on the same user -session. For example, due the following temporal file defintion: -

-
cli_getTemporalFile $FILE
-
-

If FILE name is `instance.svg' and the unique random string -is `f16f7b51-ac12-4b7f-9e66-72df847f12de', the final temporal -file, built from previous temporal file definition, would be: -

-
/tmp/centos-art.sh-f16f7b51-ac12-4b7f-9e66-72df847f12de-instance.svg
-
-

When you use the cli_getTemporalFile function to create -temporal files, be sure to remove temporal files created once you've -ended up with them. For example, consider the following construction: -

-
for FILE in $FILES;do
-
-    # Initialize temporal instance of file.
-    INSTANCE=$(cli_getTemporalFile $FILE)
-
-    # Do something ... 
-
-    # Remove temporal instance of file.
-    if [[ -f $INSTANCE ]];then
-        rm $INSTANCE
-    fi
-
-done
-
-

Use the cli_getTemporalFile function whenever you need to -create temporal files inside `centos-art.sh' script. -

- -
-
Function: cli_getThemeName - -
-

Output theme name. -

-

In order for cli_getThemeName function to extract theme name -correctly, the ACTIONVAL variable must contain a directory path -under `trunk/Identity/Themes/Motifs/' directory structure. -Otherwise, cli_getThemeName returns an empty string. -

- -
-
Function: cli_printMessage MESSAGE [FORMAT] - -
-

Define standard output message definition supported by -`centos-art.sh' script. -

-

When FORMAT is not specified, cli_printMessage outputs -information just as it was passed in MESSAGE variable. -Otherwise, FORMAT can take one of the following values: -

-
-
`AsHeadingLine'
-

To print heading messages. -

----------------------------------------------------------------------
-$MESSAGE
-----------------------------------------------------------------------
-
-
-
`AsWarningLine'
-

To print warning messages. -

----------------------------------------------------------------------
-WARNING: $MESSAGE

-
-
-
`AsNoteLine'
-

To print note messages. -

----------------------------------------------------------------------
-NOTE: $MESSAGE

-
-
-
`AsResponseLine'
-

To print response messages on one-column format. -

--> $MESSAGE
-
-
-
`AsRequestLine'
-

To print request messages on one-column format. Request messages -output messages with one colon (`:') and without trailing newline -(`\n') at message end. -

$MESSAGE:
-
-
-
`AsYesOrNoRequestLine'
-

To print `yes or no' request messages on one-column format. If -something different from `y' is answered (when using -en_US.UTF-8 locale), script execution ends immediatly. -

-
$MESSAGE [y/N]:
-
-

When we use `centos-art.sh' script in a locale different from -en_US.UTF-8, confirmation answer may be different from -`y'. For example, if you use es_ES.UTF-8 locale, the -confirmation question would look like: -

-
$MESSAGE [s/N]:
-
-

and the confirmation answer would be `s', as it is on Spanish -`sí' word. -

-

Definition of which confirmation word to use is set on translation -messages for your specific locale information. -- Removed(xref:trunk Scripts -Bash Functions Locale) --, for more information about locale-specific -translation messages. -

-
-
`AsToKnowMoreLine'
-

To standardize `to know more, run the following command:' -messages. When the `AsToKnowMoreLine' option is used, the -MESSAGE value should be set to "$(caller)". caller -is a Bash builtin that returns the context of the current subroutine -call. `AsToKnowMoreLine' option uses caller builtin -output to build documentation entries dynamically. -

-
----------------------------------------------------------------------
-To know more, run the following command:
-centos-art manual --read='path/to/dir'
-----------------------------------------------------------------------
-
-

Use `AsToKnowMoreLine' option after errors and for intentional -script termination. -

-
-
`AsRegularLine'
-

To standardize regular messages on one-column format. -

-

When MESSAGE contains a colon inside (e.g., `description: -message'), the cli_printMessage function outputs MESSAGE -on two-columns format. -

-
- -

Use cli_printMessage function whenever you need to output -information from `centos-art.sh' script. -

-

2.68 The `trunk/Scripts/Bash/Cli/Functions/Locale' Directory

- - - -

2.68.1 Goals

- - - - - -

2.68.2 Description

- -

This command looks for `.sh' files inside Bash directory and -extracts translatable strings from files, using xgettext -command, in order to create a portable object template -(`centos-art.sh.pot') file for them. -

-

With the `centos-art.sh.pot' file up to date, the -centos-art command removes the temporal list of files sotred -inside `/tmp' directory and checks the current language of your -user's session to create a portable object file for it, in the -location `$CLI_LANG/$CLI_LANG.po'. -

-

The CLI_LANG variable discribes the locale language used to -output messages inside centos-art command. The locale -language used inside centos-art command is taken from the -LANG environment variable. The CLI_LANG variable has the -`LL_CC' format, where `LL' is a language code from the -ISO-639 standard, and `CC' a country code from the ISO-3166 -standard. -

-

The LANG environment variable is set when you do log in to your -system. If you are using a graphical session, change language to your -native language and do login. That would set and exoprt the LANG -environment variable to the correct value. On the other side, if you -are using a text session edit your `~/.bash_profile' file to set -and export the LANG environment variable to your native locale -as defines the locale -a command output; do logout, and do -login again. -

-

At this point, the LANG environment variable has the appropriate -value you need, in order to translate centos-art.sh messages -to your native language (the one set in LANG environment -variable). -

-

With the `$CLI_LANG/$CLI_LANG.po' file up to date, the -centos-art opens it for you to update translation strings. -The centos-art command uses the value of EDITOR -environment variable to determine your favorite text editor. If no -value is defined on EDITOR, the `/usr/bin/vim' text editor -is used as default. -

-

When you finishd PO file edition and quit text editor, the -centos-art command creates the related machine object in the -location `$CLI_LANG/LC_MESSAGES/$TEXTDOMAIN.mo'. -

-

At this point, all translations you made in the PO file should be -available to your language when runing centos-art.sh script. -

-

In order to make the centos-art.sh internationalization, the -centos-art.sh script was modified as described in the -gettext info documentation (info gettext). You -can find such modifications in the following files: -

- - - - - - -

2.68.3 Usage

- -
-
`centos-art locale --edit'
-

Use this command to translate command-line interface output messages -in the current system locale you are using (as specified in LANG -environment variable). -

-
`centos-art locale --list'
-

Use this command to see the command-line interface locale report. -

2.70 The `trunk/Scripts/Bash/Cli/Functions/Path' Directory

- - - -

2.70.1 Goals

- -

This section exists to organize files related to path -functiontionality. The path functionality standardizes -movement, syncronization, branching, tagging, and general file -maintainance inside the repository. -

- - -

2.70.2 Description

- -

"CentOS like trees, has roots, trunk, branches, leaves and -flowers. Day by day they work together in freedom, ruled by the laws -of nature and open standards, to show the beauty of its existence." -

- - -

2.70.2.1 Repository layout

- -

The repository layout describes organization of files and directories -inside the repository. The repository layout provides the standard -backend required for automation scripts to work correctly. If such -layout changes unexpectedly, automation scripts may confuse themselves -and stop doing what we expect from them to do. -

-

As convenction, inside CentOS Artwork Repository, we organize files -and directories related to CentOS corporate visual identity under -three top level directories named: `trunk/', `branches/', -and `tags/'. -

-

The `trunk/' directory (see section The `trunk' Directory) organizes the main -development line of CentOS corporate visual identity. Inside -`trunk/' directory structure, the CentOS corporate visual -identity concepts are implemented using directories. There is one -directory level for each relevant concept inside the repository. The -`trunk/' directory structure is mainly used to perform -development tasks related to CentOS corporate visual identity. -

-

The `branches/' directory () oranizes -parallel development lines to `trunk/' directory. The -`branches/' directory is used to set points in time where -develpment lines are devided one from another taking separte and -idependent lives that share a common past from the point they were -devided on. The `branches/' directory is mainly used to perform -quality assurance tasks related to CentOS corporate visual identity. -

-

The `tags/' directory (see section The `tags' Directory) organizes parallel frozen -lines to `branches/' directory. The parallel frozen lines are -immutable, nothing change inside them once they has been created. The -`tags/' directory is mainly used to publish final releases of -CentOS corporate visual identity. -

-

The CentOS Artwork Repository layout is firmly grounded on a -Subversion base. Subversion (http://subversion.tigris.org) is a -version control system, which allows you to keep old versions of files -and directories (usually source code), keep a log of who, when, and -why changes occurred, etc., like CVS, RCS or SCCS. Subversion keeps a -single copy of the master sources. This copy is called the source -"repository"; it contains all the information to permit extracting -previous versions of those files at any time. -

- - -

2.70.2.2 Repository name convenctions

- -

Repository name convenctions help us to maintain consistency of names -inside the repository. -

-

Repository name convenctions are applied to files and directories -inside the repository layout. As convenction, inside the repository -layout, file names are all written in lowercase -(`01-welcome.png', `splash.png', `anaconda_header.png', -etc.) and directory names are all written capitalized (e.g., -`Identity', `Themes', `Motifs', `TreeFlower', -etc.). -

-

Repository name convenctions are implemented inside the -cli_getRepoName function of `centos-art.sh' script. With -cli_getRepoName function we reduce the amount of commands and -convenctions to remember, concentrating them in just one single place -to look for fixes and improvements. -

- - -

2.70.2.3 Repository work flow

- -

Repository work flow describes the steps and time intervals used to -produce CentOS corporate visual identity inside CentOS Artwork -Repository. -

-

To illustrate repository work flow let's consider themes' development -cycle. -

-

Initially, we start working themes on their trunk development line -(e.g., `trunk/Identity/Themes/Motifs/TreeFlower/'), here we -organize information that cannot be produced automatically (i.e., -background images, concepts, color information, screenshots, etc.). -

-

Later, when theme trunk development line is considered "ready" for -implementation (e.g., all required backgrounds have been designed), -we create a branch for it (e.g., -`branches/Identity/Themes/Motifs/TreeFlower/1/'). Once the -branch has been created, we forget that branch and continue working -the trunk development line while others (e.g., an artwork quality -assurance team) test the new branch for tunning it up. -

-

Once the branch has been tunned up, and considered "ready" for -release, it is freezed under `tags/' directory (e.g., -`tags/Identity/Themes/Motifs/TreeFower/1.0/') for packagers, -webmasters, promoters, and anyone who needs images from that CentOS -theme the tag was created for. -

-

Both branches and tags, inside CentOS Artwork Repository, use -numerical values to identify themselves under the same location. -Branches start at one (i.e., `1') and increment one unit for each -branch created from the same trunk development line. Tags start at -zero (i.e., `0') and increment one unit for each tag created from -the same branch development line. -

-
Convenction

Convenction

Do not freeze trunk development lines using tags -directly. If you think you need to freeze a trunk development line, -create a branch for it and then freeze that branch instead. -

- -

The trunk development line may introduce problems we cannot see -immediatly. Certainly, the high changable nature of trunk development -line complicates finding and fixing such problems. On the other hand, -the branched development lines provide a more predictable area where -only fixes/corrections to current content are commited up to -repository. -

-

If others find and fix bugs inside the branched development line, we -could merge such changes/experiences back to trunk development line -(not visversa) in order for future branches, created from trunk, to -benefit. -

-

Time intervals used to create branches and tags may vary, just as -different needs may arrive. For example, consider the release schema -of CentOS distribution: one major release every 2 years, security -updates every 6 months, support for 7 years long. Each time a CentOS -distribution is released, specially if it is a major release, there is -a theme need in order to cover CentOS distribution artwork -requirements. At this point, is where CentOS Artwork Repository comes -up to scene. -

-

Before releasing a new major release of CentOS distribution we create -a branch for one of several theme development lines available inside -the CentOS Artwork Repository, perform quality assurance on it, and -later, freeze that branch using tags. Once a the theme branch has been -frozen (under `tags/' directory), CentOS Packagers (the persons -whom build CentOS distribution) can use that frozen branch as source -location to fulfill CentOS distribution artwork needs. The same -applies to CentOS Webmasters (the persons whom build CentOS websites), -and any other visual manifestation required by the project. -

- - -

2.70.2.4 Parallel directories

- -

Inside CentOS Artwork Repository, parallel directories are simple -directory entries built from a common parent directory and placed in a -location different to that, the common parent directory is placed on. -Parallel directories are useful to create branches, tags, -translations, documentation, pre-rendering configuration script, and -similar directory structures. -

-

Parallel directories take their structure from one unique parent -directory. Inside CentOS Artwork Repository, this unique parent -directory is under `trunk/Identity' location. The -`trunk/Identity' location must be considered the reference for -whatever information you plan to create inside the repository. -

-

In some circumstances, parallel directories may be created removing -uncommon information from their paths. Uncommon path information -refers to those directory levels in the path which are not common for -other parallel directories. For example, when rendering -`trunk/Identity/Themes/Motifs/TreeFlower/Distro' directory -structure, the `centos-art.sh' script removes the -`Motifs/TreeFlower/' directory levels from path, in order to -build the parallel directory used to retrived translations, and -pre-rendering configuration scripts required by render -functionality. -

-

Another example of parallel directory is the documentation structure -created by manual functionality. This time, -`centos-art.sh' script uses parallel directory information with -uncommon directory levels to build the documentation entry required by -Texinfo documentation system, inside the repository. -

-

Othertimes, parallel directories may add uncommon information to their -paths. This is the case we use to create branches and tags. When we -create branches and tags, a numerical identifier is added to parallel -directory structure path. The place where the numerical identifier is -set on is relevant to corporate visual identity structure and should -be carefully considered where it will be. -

-

When one parent directory changes, all their related parallel -directories need to be changed too. This is required in order for -parallel directories to retain their relation with the parent -directory structure. In the other hand, parallel directories should -never be modified under no reason but to satisfy the relation to their -parent directory structure. Liberal change of parallel directories -may suppresses the conceptual idea they were initially created for; -and certainly, things may stop working the way they should do. -

- - -

2.70.2.5 Syncronizing path information

- -

Parallel directories are very useful to keep repository organized but -introduce some complications. For instance, consider what would -happen to functionalities like manual (`trunk Scripts Bash -Functions Manual') that rely on parent directory structures to create -documentation entries (using parallel directory structures) if one of -those parent directory structures suddenly changes after the -documentation entry has been already created for it? -

-

In such cases, functionalities like manual may confuse -themselves if path information is not updated to reflect the relation -with its parent directory. Such functionalities work with parent -directory structure as reference; if a parent directory changes, the -functionalities dont't even note it because they work with the last -parent directory structure available in the repository, no matter what -it is. -

-

In the specific case of documentation (the manual -functionality), the problem mentioned above provokes that older parent -directories, already documented, remain inside documentation directory -structures as long as you get your hands into the documentation -directory structure (`trunk/Manuals') and change what must be -changed to match the new parent directory structure. -

-

There is no immediate way for manual, and similar -functionalities that use parent directories as reference, to know when -and how directory movements take place inside the repository. Such -information is available only when the file movement itself takes -place inside the repository. So, is there, at the moment of moving -files, when we need to syncronize parallel directories with their -unique parent directory structure. -

-
Warning

Warning

There is not support for URL reference inside -`centos-art.sh' script. The `centos-art.sh' script is -designed to work with local files inside the working copy only. -

- -

As CentOS Artwork Repository is built over a version control system, -file movements inside the repository are considered repository -changes. In order for these repository changes to be versioned, we -need to, firstly, add changes into the version control system, commit -them, and later, perform movement actions using version control system -commands. This configuration makes possible for everyone to know about -changes details inside the repository; and if needed, revert or update -them back to a previous revision. -

-

Finally, once all path information has been corrected, it is time to -take care of information inside the files. For instance, considere -what would happen if you make a reference to a documentation node, and -later the documentation node you refere to is deleted. That would make -Texinfo to produce error messages at export time. So, the -`centos-art.sh' script needs to know when such changes happen, in -a way they could be noted and handled without producing errors. -

- - -

2.70.2.6 What is the right place to store it?

- -

Occasionly, you may find that new corporate visual identity components -need to be added to the repository. If that is your case, the first -question you need to ask yourself, before start to create directories -blindly all over, is: What is the right place to store it? -

-

The CentOS Community different free support vains (see: -http://wiki.centos.org/GettingHelp) are the best place to find -answers to your question, but going there with hands empty is not good -idea. It may give the impression you don't really care about. Instead, -consider the following suggestions to find your own comprehension and -so, make your propositions based on it. -

-

When we are looking for the correct place to store new files, to bear -in mind the corporate visual identity structure used inside the CentOS -Artwork Repository (see section The `trunk/Identity' Directory) would be probaly the best -advice we could offer, the rest is just matter of choosing appropriate -names. To illustrate this desition process let's consider the -`trunk/Identity/Themes/Motifs/TreeFlower' directory as example. -It is the trunk development line of TreeFlower artistic motif. -Artistic motifs are considered part of themes, which in turn are -considered part of CentOS corporate visual identity. -

-

When building parent directory structures, you may find that reaching -an acceptable location may take some time, and as it uses to happen -most of time; once you've find it, that may be not a definite -solution. There are many concepts that you need to play with, in -order to find a result that match the conceptual idea you try to -implement in the new directory location. To know which these concepts -are, split the location in words and read its documentation entry from -less specific to more specific. -

-

For example, the `trunk/Identity/Themes/Motifs/TreeFlower' -location evolved through several months of contant work and there is -no certain it won't change in the future, even it fixes quite well the -concept we are trying to implement. The concepts used in -`trunk/Identity/Themes/Distro/Motifs/TreeFlower' location are -described in the following commands, respectively: -

-
centos-art manual --read=turnk/
-centos-art manual --read=turnk/Identity/
-centos-art manual --read=turnk/Identity/Themes/
-centos-art manual --read=turnk/Identity/Themes/Motifs/
-centos-art manual --read=turnk/Identity/Themes/Motifs/TreeFlower/
-
-

Other location concepts can be found similary as we did above, just -change the location we used above by the one you are trying to know -concepts for. -

- - -

2.70.3 Usage

- -
-
centos-art path --copy='SRC' --to='DST'
-
-

Copy `SRC' to `DST' and schedule `DST' for -addition (with history). In this command, `SRC' and `DST' -are both working copy (WC) entries. -

-
-
centos-art path --delete='SRC'
-
-

Delete `DST'. In order for this command to work the file or -directory you intend to delete should be under version control first. -In this command, `SRC' is a working copy (WC) entry. -

2.71 The `trunk/Scripts/Bash/Cli/Functions/Render' Directory

- -

The render functionality exists to produce both identity and -translation files on different levels of information (i.e., different -languages, release numbers, architectures, etc.). -

-

The render functionality relies on "renderable directory -structures" to produce files. Renderable directory structures can be -either "identity directory structures" or "translation directory -structures" with special directories inside. -

- - -

2.71.1 Renderable identity directory structures

- -

Renderable identity directory structures are the starting point of -identity rendition. Whenever we want to render a component of CentOS -corporate visual identity, we need to point `centos-art.sh' to a -renderable identity directory structure. If such renderable identity -directory structure doesn't exist, then it is good time to create it. -

-

Inside the working copy, one renderable identity directory structures -represents one visual manifestation of CentOS corporate visual -identity, or said differently, each visual manifestation of CentOS -corporate visual identity should have one renderable identity -directory structure. -

-

Inside renderable identity directory structures, `centos-art.sh' -can render both image-based and text-based files. Specification of -whether a renderable identity directory structure produces image-based -or text-based content is a configuration action that takes place in -the pre-rendition configuration script of that renderable identity -directory structure. -

-

Inside renderable identity directory structures, content production is -organized in different configurations. A content production -configuration is a unique combination of the components that make an -identity directory structure renderable. One content production -configuration does one thing only (e.g., to produce untranslated -images), but it can be extended (e.g., adding translation files) to -achieve different needs (e.g., to produce translated images). -

- - -

2.71.1.1 Design template without translation

- -

The design template without translation configuration is based on a -renderable identity directory structure with an empty translation -directory structure. In this configuration, one design template -produces one untranslated file. Both design templates and final -untranslated files share the same file name, but they differ one -another in file-type and file-extension. -

-

For example, to produce images without translations (there is no much -use in producing text-based files without translations), consider the -following configuration: -

-
-
One renderable identity directory structure:
-
-

In this example we used `Identity/Path/To/Dir' as the identity -component we want to produce untranslated images for. Identity -components can be either under `trunk/' or `branches/' -directory structure. -

-

The identity component (i.e., `Identity/Path/To/Dir', in this -case) is also the bond component we use to connect the identity -directory structures with their respective auxiliar directories (i.e., -translation directory structres and pre-rendition configuration -structures). The bond component is the path convenction that -`centos-art.sh' uses to know where to look for related -translations, configuration scripts and whatever auxiliar thing a -renderable directory structure may need to have. -

-
      | The bond component
-      |----------------->|
-trunk/Identity/Path/To/Dir  <-- Renderable identity directory structure.
-|-- Tpl                     <-- Design template directory.
-|   `-- file.svg            <-- Design template file.
-`-- Img                     <-- Directory used to store final files.
-    `-- file.png            <-- Final image-based file produced from
-                                design template file.
-
-

Inside design template directory, design template files are based on -SVG (Scalable Vector Graphics) and use the extension -.svg. Design template files can be organized using several -directory levels to create a simple but extensible configuration, -specially if translated images are not required. -

-

In order for SVG (Scalable Vector Graphics) files to be -considered "design template" files, they should be placed under the -design template directory and to have set a CENTOSARTWORK -object id inside. -

-

The CENTOSARTWORK word itself is a convenction name we use to -define which object/design area, inside a design template, the -`centos-art.sh' script will use to export as -PNG (Portable Network Graphic) image at rendition time. -Whithout such object id specification, the `centos-art.sh' script -cannot know what object/design area you (as designer) want to export -as PNG (Portable Network Graphic) image file. -

-
info

Note

At rendition time, the content of `Img/' directory -structure is produced by `centos-art.sh' automatically. -

- -

When a renderable identity directory structure is configured to -produce image-based content, `centos-art.sh' produces -PNG (Portable Network Graphics) files with the .png -extension. Once the base image format has been produced, it is -possible for `centos-art.sh' to use it in order to automatically -create other image formats that may be needed (-- Removed(pxref:trunk Scripts -Bash Functions Render Config) --). -

-

Inside the working copy, you can find an example of "design template -without translation" configuration at `trunk/Identity/Models/'. -

-

See section The `trunk/Identity' Directory, for more information. -

-
-
One translation directory structure:
-
-

In order for an identity entry to be considered an identity renderable -directory structure, it should have a translation entry. The content -of the translation entry is relevant to determine how to process the -identity renderable directory entry. -

-

If the translation entry is empty (i.e., there is no file inside it), -`centos-art.sh' interprets the identity renderable directory -structure as a "design templates without translation" configuration. -

-trunk/Translations/Identity/Path/To/Dir
-`-- (empty)
-
-

If the translation entry is not empty, `centos-art.sh' can -interpret the identity renderable directory structure as one of the -following configurations: "design template with translation -(one-to-one)" or "design template with translation (optimized)". -Which one of these configurations is used depends on the value -assigned to the matching list (MATCHINGLIST) variable in the -pre-rendition configuration script of the renderable identity -directory structure we are producing images for. -

-

If the matching list variable is empty (as it is by default), then -"design template with translation (one-to-one)" configuration is -used. In this configuration it is required that both design templates -and translation files have the same file names. This way, one -translation files is applied to one design template, to produce -one translated image. -

-

If the matching list variable is not empty (because you redefine it in -the pre-rendition configuration script), then "design template with -translation (optimized)" configuration is used instead. In this -configuration, design templates and translation files don't need to -have the same names since such name relationship between them is -specified in the matching list properly. -

One pre-rendition configuration script:
-
-

In order to make an identity directory structure renderable, a -pre-rendition configuration script should exist for it. The -pre-rendition configuration script specifies what type of rendition -does `centos-art.sh' will perform over the identity directory -structure and how does it do that. -

-

-trunk/Scripts/Bash/Functions/Render/Config/Identity/Path/To/Dir
-`-- render.conf.sh
-
-

In this configuration the pre-rendition configuration script -(`render.conf.sh') would look like the following: -

-
function render_loadConfig {
-
-    # Define rendition actions.
-    ACTIONS[0]='BASE:renderImage'
-
-}
-
-

Since translation directory structure is empty, `centos-art.sh' -assumes a "design template without translation" configuration to -produce untranslated images. -

-

To produce untranslated images, `centos-art.sh' takes one design -template and creates one temporal instance from it. Later, -`centos-art.sh' uses the temporal design template instance as -source file to export the final untranslated image. The action of -exporting images from SVG (Scalable Vector Graphics) to -PNG (Portable Network Graphics) is possible thanks to -Inkscape's command-line interface and the CENTOSARTWORK object -id we previously set inside design templates. -

-

Finally, when the untranslated image has been created, the temporal -design template instance is removed. At this point, -`centos-art.sh' takes the next design template and repeats the -whole production flow once again (design template by design template), -until all design templates be processed. -

2.71.1.2 Design template with translation (one-to-one)

- -

Producing untranslated images is fine in many cases, but not always. -Sometimes it is required to produce images in different languages and -that is something that untrasnlated image production cannot achieve. -However, if we fill its empty translation entry with translation files -(one for each design template) we extend the production flow from -untranslated image production to translated image production. -

-

In order for `centos-art.sh' to produce images correctly, each -design template should have one translation file and each translation -file should have one design template. Otherwise, if there is a -missing design template or a missing translation file, -`centos-art.sh' will not produce the final image related to the -missing component. -

-

In order for `centos-art.sh' to know which is the relation -between translation files and design templates the translation -directory structure is taken as reference. For example, the -`trunk/Translations/Identity/Path/To/Dir/file.sed' translation -file does match `trunk/Identity/Path/To/Dir/Tpl/file.svg' design -template, but it doesn't match -`trunk/Identity/Path/To/Dir/File.svg' or -`trunk/Identity/Path/To/Dir/Tpl/File.svg' or -`trunk/Identity/Path/To/Dir/Tpl/SubDir/file.svg' design -templates. -

-

The pre-rendition configuration script used to produce untranslated -images is the same we use to produce translated images. There is no -need to modify it. So, as we are using the same pre-rendition -configuration script, we can say that translated image production is -somehow an extended/improved version of untranslated image production. -

-
info

Note

If we use no translation file in the translation entry -(i.e., an empty directory), `centos-art.sh' assumes the -untranslated image production. If we fill the translation entry with -translation files, `centos-art.sh' assumes the translated image -production. -

- -

To produce final images, `centos-art.sh' applies one translation -file to one design template and produce a translated design template -instance. Later, `centos-art.sh' uses the translated template -instance to produce the translated image. Finally, when the translated -image has been produced, `centos-art.sh' removes the translated -design template instance. This production flow is repeated for each -translation file available in the translatio entry. -

2.71.1.3 Design template with translation (optimized)

- -

Producing translated images satisfies almost all our production images -needs, but there is still a pitfall in them. In order to produce -translated images as in the "one-to-one" configuration describes -previously, it is required that one translation file has one design -template. That's useful in many cases, but what would happen if we -need to apply many different translation files to the same design -template? Should we have to duplicate the same design template file -for each translation file, in order to satisfy the "one-to-one" -relation? What if we need to assign translation files to design -templates arbitrarily? -

-

Certenly, that's something the "one-to-one" configuration cannot -handle. So, that's why we had to "optimize" it. The optimized -configuration consists on using a matching list (MATCHINGLIST) -variable that specifies the relationship between translation files and -design templates in an arbitrary way. Using such matching list between -translation files and design templates let us use as many assignment -combinations as translation files and design templates we are working -with. -

-

The MATCHINGLIST variable is set in the pre-rendition -configuration script of the component we want to produce images for. -By default, the MATCHINGLIST variable is empty which means no -matching list is used. Otherwise, if MATCHINGLIST variable has a -value different to empty value then, `centos-art.sh' interprets -the matching list in order to know how translation files are applied -to design templates. -

-

For example, consider the following configuration: -

-
-
One entry under `trunk/Identity/':
-
-

In this configuration we want to produce three images using a -paragraph-based style, controlled by `paragraph.svg' design -template; and one image using a list-based style, controlled by -`list.svg' design template. -

-
trunk/Identity/Path/To/Dir
-|-- Tpl
-|   |-- paragraph.svg
-|   `-- list.svg
-`-- Img
-    |-- 01-welcome.png
-    |-- 02-donate.png
-    |-- 03-docs.png
-    `-- 04-support.png
-
-
-
One entry under `trunk/Translations/':
-
-

In order to produce translated images we need to have one translation -file for each translated image we want to produce. Notice how -translation names do match final image file names, but how translation -names do not match design template names. When we use matching list -there is no need for translation files to match the names of design -templates, such name relation is set inside the matching list itself. -

-
trunk/Translations/Identity/Path/To/Dir
-|-- 01-welcome.sed
-|-- 02-donate.sed
-|-- 03-docs.sed
-`-- 04-support.sed
-
-
-
One entry under `trunk/trunk/Scripts/Bash/Functions/Render/Config/':
-
-

In order to produce different translated images using specific design -templates, we need to specify the relation between translation files -and design templates in a way that `centos-art.sh' could know -exactly what translation file to apply to what design template. This -relation between translation files and design templates is set using -the matching list MATCHINGLIST variable inside the pre-rendition -configuration script of the component we want to produce images for. -

-
trunk/Scripts/Bash/Functions/Render/Config/Identity/Path/To/Dir
-`-- render.conf.sh
-
-

In this configuration the pre-rendition configuration script -(`render.conf.sh') would look like the following: -

-
function render_loadConfig {
-
-    # Define rendition actions.
-    ACTIONS[0]='BASE:renderImage'
-
-    # Define matching list.
-    MATCHINGLIST="\
-    paragraph.svg:\
-        01-welcome.sed\
-        02-donate.sed\
-        04-support.sed
-    list.svg:\
-        03-docs.sed
-    "
-
-}
-
-

As result, `centos-art.sh' will produce `01-welcome.png', -`02-donate.png' and `04-support.png' using the -paragraph-based design template, but `03-docs.png' using the -list-based design template. -

-
- - - -

2.71.1.4 Design template with translation (optimized+flexibility)

- -

In the production models we've seen so far, there are design templates -to produce untranslated images and translation files which combiend -with design templates produce translated images. That may seems like -all our needs are covered, doesn't it? Well, it almost does. -

-

Generally, we use design templates to define how final images will -look like. Generally, each renderable directory structure has one -`Tpl/' directory where we organize design templates for that -identity component. So, we can say that there is only one unique -design template definition for each identity component; or what is the -same, said differently, identity components can be produced in one way -only, the way its own design template directory specifies. This is -not enough for theme production. It is a limitation, indeed. -

-

Initially, to create one theme, we created one renderable directory -structure for each theme component. When we found ourselves with many -themes, and components inside them, it was obvious that the same -design model was duplicated inside each theme. As design models were -independently one another, if we changed one theme's design model, -that change was useless to other themes. So, in order to reuse design -model changes, we unified design models into one common directory -structure. -

-

With design models unified in a common structure, another problem rose -up. As design models also had the visual style of theme components, -there was no difference between themes, so there was no apparent need -to have an independent theme directory structure for each different -theme. So, it was also needed to separate visual styles from design -models. -

-

At this point there are two independent worklines: one directory -structure to store design models (the final image characteristics -[i.e., dimensions, translation markers, etc.]) and one directory -structure to store visual styles (the final image visual style [i.e., -the image look and feel]). So, it is possible to handle both -different design models and different visual styles independtly one -another and later create combinations among them using -`centos-art.sh'. -

-

For example, consider the following configuration: -

-
-
One entry under `trunk/Identity/Themes/Models/':
-
-

The design model entry exists to organize design model files (similar -to design templates). Both design models and design templates are very -similar; they both should have the CENTOSARTWORK export id -present to identify the exportation area, translation marks, etc. -However, design models do use dynamic backgrounds inclusion while -design templates don't. -

-
                        THEMEMODEL | | The bond component

-|-- paragraph.svg
-`-- list.svg
-
-

Inisde design models, dynamic backgrounds are required in order for -different artistic motifs to reuse common design models. Firstly, in -order to create dynamic backgrounds inside design models, we import a -bitmap to cover design model's background and later, update design -model's path information to replace fixed values to dynamic values. -

-
-
One entry under `trunk/Identity/Themes/Motifs/':
-
-

The artistic motif entry defines the visual style we want to produce -images for, only. Final images (i.e., those built from combining both -design models and artistic motif backrounds) are not stored here, but -under branches directory structure. In the artistic motif entry, we -only define those images that cannot be produced automatically by -`centos-art.sh' (e.g., Backgrounds, Color information, -Screenshots, etc.). -

-

-
-
One entry under `trunk/Translations/':
-
-

The translation entry specifies, by means of translation files, the -language-specific information we want to produce image for. When we -create the translation entry we don't use the name of neither design -model nor artistic motif, just the design model component we want to -produce images for. -

2.71.2 Renderable translation directory structures

- -

Translation directory structures are auxiliar structures of renderable -identity directory structures. There is one translation directory -structure for each renderable identity directory structure. Inside -translation directory structures we organize translation files used by -renderable identity directory structures that produce translated -images. Renderable identity directory structures that produce -untranslated images don't use translation files, but they do use a -translation directory structure, an empty translation directory -structure, to be precise. -

-

In order to aliviate production of translation file, we made -translation directory structures renderable adding a template -(`Tpl/') directory structure to handle common content inside -translation files. This way, we work on translation templates and -later use `centos-art.sh' to produce specific translation files -(based on translation templates) for different information (e.g., -languages, release numbers, architectures, etc.). -

-

If for some reason, translation files get far from translation -templates and translation templates become incovenient to produce such -translation files then, care should be taken to avoid replacing the -content of translation files with the content of translation templates -when `centos-art.sh' is executed to produce translation files -from translation templates. -

-

Inside renderable translation directory structures, -`centos-art.sh' can produce text-based files only. -

- - -

2.71.3 Copying renderable directory structures

- -

A renderable layout is formed by design models, design images, -pre-rendition configuration scripts and translations files. This way, -when we say to duplicate rendition stuff we are saying to duplicate -these four directory structures (i.e., design models, design images, -pre-rendition configuration scripts, and related translations files). -

-

When we duplicate directories, inside `trunk/Identity' directory -structure, we need to be aware of renderable layout described above -and the source location used to perform the duplication action. The -source location is relevant to centos-art.sh script in order to -determine the required auxiliar information inside directory -structures that need to be copied too (otherwise we may end up with -orphan directory structures unable to be rendered, due the absence of -required information). -

-

In order for a renderable directory structure to be valid, the new -directory structure copied should match the following conditions: -

-
    -
  1. To have a unique directory structure under -`trunk/Identity', organized by any one of the above -organizational designs above. - -
  2. To have a unique directory structure under -`trunk/Translations' to store translation files. - -
  3. To have a unique directory structure under -`trunk/Scripts/Bash/Functions/Render/Config' to set pre-rendition -configuration script. -
- -

As convenction, the render_doCopy function uses -`trunk/Identity' directory structure as source location. Once -the `trunk/Identity' directory structure has been specified and -verified, the related path information is built from it and copied -automatically to the new location specified by FLAG_TO variable. -

-

Design templates + No translation: -

-

Command: -- centos-art render -copy=trunk/Identity/Path/To/Dir -to=trunk/Identity/NewPath/To/Dir -

-

Sources: -- trunk/Identity/Path/To/Dir -- trunk/Translations/Identity/Path/To/Dir -- trunk/Scripts/Bash/Functions/Render/Config/Identity/Path/To/Dir -

-

Targets: -- trunk/Identity/NewPath/To/Dir -- trunk/Translations/Identity/NewPath/To/Dir -- trunk/Scripts/Bash/Functions/Render/Config/Identity/NewPath/To/Dir -

-

Renderable layout 2: -

-

Command: -- centos-art render -copy=trunk/Identity/Themes/Motifs/TreeFlower \ - -to=trunk/Identity/Themes/Motifs/NewPath/To/Dir -

-

Sources: -- trunk/Identity/Themes/Motifs/TreeFlower -- trunk/Translations/Identity/Themes -- trunk/Translations/Identity/Themes/Motifs/TreeFlower -- trunk/Scripts/Bash/Functions/Render/Config/Identity/Themes -- trunk/Scripts/Bash/Functions/Render/Config/Identity/Themes/Motifs/TreeFlower -

-

Targets: -- trunk/Identity/Themes/Motifs/NewPath/To/Dir -- trunk/Translations/Identity/Themes -- trunk/Translations/Identity/Themes/Motifs/NewPath/To/Dir -- trunk/Scripts/Bash/Functions/Render/Config/Identity/Themes -- trunk/Scripts/Bash/Functions/Render/Config/Identity/Themes/Motifs/NewPath/To/Dir -

-

Notice that design models are not included in source or target -locations. This is intentional. In "Renderable layout 2", design -models live by their own, they just exist, they are there, available -for any artistic motif to use. By default `Themes/Models/Default' -design model directory structure is used, but other design models -directory structures (under Themes/Models/) can be created and used -changing the value of THEMEMODEL variable inside the pre-rendition -configuration script of the artistic motif source location you want to -produce. -

-

Notice how translations and pre-rendition configuration scripts may -both be equal in source and target. This is because such structures -are common to all artistic motifs (the default values to use when no -specific values are provided). -

-

- The common directory structures are not copied or deleted. We cannot - copy a directory structure to itself. -

-

- The common directory structures represent the default value to use - when no specific translations and/or pre-rendition configuration - script are provided inside source location. -

-

- The specific directory structures, if present, are both copiable and - removable. This is, when you perform a copy or delete action from - source, that source specific auxiliar directories are transfered in - the copy action to a new location (that specified by FLAG_TO - variable). -

-

- When translations and/or pre-rendition configuration scripts are - found inside the source directory structure, the centos-art.sh - script loads common auxiliar directories first and later specific - auxiliar directories. This way, identity rendition of source - locations can be customized idividually over the base of common - default values. -

-

- The specific auxiliar directories are optional. -

-

- The common auxiliar directories should be present always. This is, - in order to provide the information required by render functionality - (i.e., to make it functional in the more basic level of its - existence). -

-

Notice how the duplication process is done from `trunk/Identity' on, -not the oposite. If you try to duplicate a translation structure (or -similar auxiliar directory structures like pre-rendition configuration -scripts), the `trunk/Identity' for that translation is not created. -This limitation is impossed by the fact that many `trunk/Identity' -directory structures may reuse/share the same translation directory -structure. We cannot delete one translation (or similar) directory -structures while a related `trunk/Identity/' directory structure is -still in need of it. -

-

The `render_doCopy' functionality does duplicate directory structures -directly involved in rendition process only. Once such directories -have been duplicated, the functionality stops thereat. -

2.72 The `trunk/Scripts/Bash/Cli/Functions/Render/Config' Directory

- - - -

2.72.1 Goals

- -

The `trunk/Scripts/Bash/Config' directory exists to oraganize -pre-rendering configuration scripts. -

- - -

2.72.2 Description

- -

Pre-rendering configuration scripts let you customize the way -centos-art.sh script renders identity and translation -repository entries. Pre-rendering configuration scripts are -`render.conf.sh' files with render_loadConfig function -definition inside. -

-

There is one `render.conf.sh' file for each pre-rendering -configuration entry. Pre-rendering configuration entries can be based -both on identity and translation repository entires. Pre-rendering -configuration entries are required for each identity entry, but not -for translation entries. -

- - -

2.72.2.1 The `render.conf.sh' identity model

- -

Inside CentOS Artwork Repository, we consider identity entries to all -directories under `trunk/Identity' directory. Identity entries can be -image-based or text-based. When you render image-based identity -entries you need to use image-based pre-rendering configuration -scripts. Likewise, when you render text-based identity entries you -need to use text-based pre-rendering configuration scripts. -

-

Inside identity pre-rendering configuration scripts, image-based -pre-rendering configuration scripts look like the following: -

-
#!/bin/bash
-
-function render_loadConfig {
-
-    # Define rendering actions.
-    ACTIONS[0]='BASE:renderImage'
-    ACTIONS[1]='POST:renderFormats: tif xpm pdf ppm'
-
-}
-
-

Inside identity pre-rendering configuration scripts, text-based -pre-rendering configuration scripts look like the following: -

-
#!/bin/bash
-
-function render_loadConfig {
-
-    # Define rendering actions.
-    ACTIONS[0]='BASE:renderText'
-    ACTIONS[1]='POST:formatText: --width=70 --uniform-spacing'
-
-}
-
-

When using identity pre-rendering configuration scripts, you can -extend both image-based and text-based pre-rendering configuration -scripts using image-based and text-based post-rendering actions, -respectively. -

- - -

2.72.2.2 The `render.conf.sh' translation model

- -

Translation pre-rendering configuration scripts take precedence before -default translation rendering action. Translation pre-rendering -actions are useful when default translation rendering action do not -fit itself to translation entry rendering requirements. -

- - -

2.72.2.3 The `render.conf.sh' rendering actions

- -

Inside both image-based and text-based identity pre-rendering -configuration scripts, we use the `ACTIONS' array variable to -define the way centos-art.sh script performs identity -rendering. Identity rendering is organized by one `BASE' action, -and optional `POST' and `LAST' rendering actions. -

-

The `BASE' action specifies what kind of rendering does the -centos-art.sh script will perform with the files related to -the pre-rendering configuration script. The `BASE' action is -required. Possible values to `BASE' action are either -`renderImage' or `renderText' only. -

-

To specify the `BASE' action you need to set the `BASE:' -string followed by one of the possible values. For example, if you -want to render images, consider the following definition of -`BASE' action: -

-
ACTIONS[0]='BASE:renderImage'
-
-

Only one `BASE' action must be specified. If more than one -`BASE' action is specified, the last one is used. If no -`BASE' action is specified at all, an error is triggered and the -centos-art.sh script ends its execution. -

-

The `POST' action specifies which action to apply for -each file rendered (at the rendering time). This action is optional. -You can set many different `POST' actions to apply many different -actions over the same already rendered file. Possible values to -`POST' action are `renderFormats', `renderSyslinux', -`renderGrub', etc. -

-

To specify the `POST' action, you need to use set the -`POST:' followed by the function name of the action you want to -perform. The exact form depends on your needs. For example, consider -the following example to produce `xpm', `jpg', and -`tif' images, based on already rendered `png' image, and -also organize the produced files in directories named as their own -extensions: -

-
ACTIONS[0]='BASE:renderImage'
-ACTIONS[1]='POST:renderFormats: xpm jpg tif'
-ACTIONS[2]='POST:groupByFormat: png xpm jpg tif'
-
-

In the previous example, file organization takes place at the moment -of rendering, just after producing the `png' base file and before -going to the next file in the list of files to render. If you don't -want to organized the produced files in directories named as their own -extensions, just remove the `POST:groupByFormat' action line: -

-
ACTIONS[0]='BASE:renderImage'
-ACTIONS[1]='POST:renderFormats: xpm jpg tif'
-
-

The `LAST' action specifies which actions to apply once the last -file in the list of files to process has been rendered. The -`LAST' action is optional. Possible values for `LAST' -actions may be `groupByFormat', `renderGdmTgz', etc. -

-
info

Note

-- Removed(xref:trunk Scripts Bash Functions Render) --, to know more -about possible values for `BASE', `POST' and `LAST' -action definitions. -

- -

To specify the `LAST' action, you need to set the `LAST:' -string followed by the function name of the action you want to -perform. For example, consider the following example if you want to -render all files first and organize them later: -

-
ACTIONS[0]='BASE:renderImage'
-ACTIONS[1]='POST:renderFormats: xpm jpg tif'
-ACTIONS[2]='LAST:groupByformat: png xpm jpg tif'
-
- - -

2.72.3 Usage

- -

Use the following commands to administer both identity and translation -pre-rendering configuration scripts: -

-
-
`centos-art config --create='path/to/dir/''
-
-

Use this command to create `path/to/dir' related pre-rendering -configuration script. -

-
-
`centos-art config --edit='path/to/dir/''
-
-

Use this command to edit `path/to/dir' related pre-rendering -configuration script. -

-
-

2.73 The `trunk/Scripts/Bash/Cli/Functions/Shell' Directory

- - - -

2.73.1 Goals

- -

This section exists to organize files related to shell -functionality of `centos-art.sh' script. -

- - -

2.73.2 Description

- -

The shell functionality of `centos-art.sh' script helps -you to maintain bash scripts inside repository. For example, suppose -you've created many functionalities for `centos-art.sh' script, -and you want to use a common copyright and license note for -consistency in all your script files. If you have a bunch of files, -doing this one by one wouldn't be a big deal. In contrast, if the -amount of files grows, updating the copyright and license note for all -of them would be a task rather tedious. The shell functionality -exists to solve maintainance tasks just as the one previously -mentioned. -

-

When you use shell functionality to update copyright inside -script files, it is required that your script files contain (at least) -the following top commentary structure: -

-
-
 1| #!/bin/bash
- 2| #
- 3| # doSomething.sh -- The function description goes here.
- 4| # 
- 5| # Copyright
- 6| #
- 7| # ...
- 8| #
- 9| # ----------------------------------------------------------------------
-10| # $Id$
-11| # ----------------------------------------------------------------------
-12|
-13| function doSomething {
-14|     
-15| }
-
-

Figure 2.4: The functions script base comment structure - -

-

Relevant lines in the above structure are lines from 5 to 9. -Everything else in the file is left immutable. -

-

When you are updating copyright through shell -functionality, the `centos-art.sh' script replaces everything -in-between line 5 --the first one matching `^# Copyright .+$' -string-- and line 9--the first long dash separator matching `^# --+$'-- with the content of copyright template instance. -

-
Caution

Caution

Be sure to add the long dash separator that matches -`^# -+$' regular expression before the function -definition. Otherwise, if the `Copyright' line is present but no -long dash separator exists, `centos-art.sh' will remove anything -in-between the `Copyright' line and the end of file. This way you -may lost your function definitions entirely. -

- -

The copyright template instance is created from one copyright template -stored in the `Config/tpl_forCopyright.sed' file. The template -instance is created once, and later removed when no longer needed. At -this moment, when template instance is created, the -`centos-art.sh' script takes advantage of automation in order to -set copyright full name and date dynamically. -

-

When you use shell functionality to update copyright, the first -thing `shell' functionality does is requesting copyright -information to user, and later, if values were left empty (i.e., no -value was typed before pressing RET key), the `shell' -functionality uses its own default values. -

-

When shell functionality uses its own default values, the final -copyright note looks like the following: -

-
-
 1| #!/bin/bash
- 2| #
- 3| # doSomthing.sh -- The function description goes here.

-
-

Figure 2.5: The function script comment example - -

-

Relevant lines in the above structure are lines from 5 to 22. Pay -attention how the copyright line was built, and how the license was -added into the top comment where previously was just three dots. -Everything else in the file was left immutable. -

-

To change copyright information (i.e., full name or year information), -run the shell functionality over the root directory containing -the script files you want to update copyright in and enter the -appropriate information when it be requested. You can run the -shell functionality as many times as you need to. -

-

To change copyright license (i.e., the text in-between lines 7 and -20), you need to edit the `Config/tpl_forCopyright.sed' file, set -the appropriate information, and run the shell functionality -once again for changes to take effect over the files you specify. -

-

Do not change the license information under which `centos-art.sh' -script is released. Instead, if you think a different license must be -used, please share your reasons at CentOS Developers mailing list. -

- - - -

2.73.3 Usage

- -
-
centos-art sh --update-copyright='path/to/dir'
-
centos-art sh --update-copyright='path/to/dir' --filter='regex'
-

Use these commands to update copyright information in `.sh' files -under `path/to/dir' directory. -

-
- -

When you provide `--filter='regex'' argument, the list of files -to process is reduced as specified in `regex' regular expression. -Inside `centos-art.sh' script, the `regex' regular -expression is used in combination with find command to look -for files matching the regular expression path pattern. -

-
Warning

Warning

In order for `regex' regular expression to match -a file, the `regex' regular expresion must match the whole file -path not just the file name. -

- -

For example, if you want to match all `render.conf.sh' files -inside `path/to/dir', use the .+/render.conf regular -expression. Later, `centos-art.sh' script uses this value inside -^$REGEX\.sh$ expression in order to build the final regular -expression (i.e., ^.+/render.conf\.sh$) that is evaluated -against available file paths inside the list of files to process. -

-

Exceptionally, when you provide `--filter='regex'' in the way -that `regex', appended to `path/to/dir/' (i.e. -`path/to/dir/regex'), matches a regular file; the -`centos-art.sh' script uses the file matching as only file in the -list of files to process. -

2.74 The `trunk/Scripts/Bash/Cli/Functions/Svg' Directory

- - - -

2.74.1 Goals

- -

This section exists to organize files related to svg -functionality of `centos-art.sh' script. -

- - -

2.74.2 Description

- -

The svg functionality of `centos-art.sh' script helps you -to maintain scalable vector graphics (SVG) inside repository. For -example, suppose you've been working in CentOS default design models -under `trunk/Identity/Themes/Models/', and you want to set common -metadata to all of them, and later remove all unused SVG defintions -from `*.svg' files. Doing so file by file may be a tedious task, -so the `centos-art.sh' script provides the svg -functionality to aid you maintain such actions. -

- - - -

2.74.2.1 Metadata maintainance

- -

The metadata used is defined by Inkscape 0.46 using the SVG standard -markup. The `centos-art.sh' script replaces everything -in-between <metadata and </metadata> tags with a -predefined metadata template we've set for this purpose. -

-

The metadata template was created using the metadata information of a -file which, using Inkscape 0.46, all metadata fields were set. This -created a complete markup representation of how SVG metadata would -look like. Later, we replaced every single static value with a -translation marker in the form `=SOMETEXT=', where -SOMETEXT is the name of its main opening tag. Later, we -transform the metadata template into a sed replacement set of commads -escaping new lines at the end of each line. -

-

With metadata template in place, the `centos-art.sh' script uses -it to create a metadata template instance for the file being processed -currently. The metadata template instance contains the metadata -portion of sed replacement commands with translation markers already -traduced. In this action, instance creation, is where we take -advantage of automation and generate metadata values like title, date, -keywords, source, identifier, and relation dynamically, based on the -file path `centos-art.sh' script is currently creating metadata -information for. -

-

With metadata template instance in place, the `centos-art.sh' -script uses it to replace real values inside all `.svg' files -under the current location you're running the `centos-art.sh' -script on. Default behaviour is to ask user to enter each metadatum -required, one by one. If user leaves metadatum empty, by pressing -RET key, `centos-art.sh' uses its default value. -

-

The `centos-art.sh' script modifies the following metadata: -

-
-
`Title'
-

Name by which this document is formally known. If no value is set -here, `centos-art.sh' script uses the file name as title. -

-
-
`Date'
-

Date associated with the creation of this document (YYYY-MM-DD). If no -value is set here, `centos-art.sh' script uses the current date -information as in date +%Y-%m-%d. -

-
-
`Creator'
-

Name of entity primarily responsible for making the content of this -document. If no value is set here, `centos-art.sh' script uses -the string `The CentOS Project'. -

-
-
`Rights'
-

Name of entity with rights to the intellectual Property of this -document. If no value is set here, `centos-art.sh' script uses -the string `The CentOS Project'. -

-
-
`Publisher'
-

Name of entity responsible for making this document available. If no -value is set here, `centos-art.sh' script uses the string -`The CentOS Project'. -

-
-
`Identifier'
-

Unique URI to reference this document. If no value is set here, -`centos-art.sh' script uses the current file path to build the -related url that points to current file location inside repository -central server. -

-
-
`Source'
-

Unique URI to reference the source of this document. If no value is -set here, `centos-art.sh' script uses current file path to build -the related url that points to current file location inside repository -central server. -

-
-
`Relation'
-

Unique URI to a related document. If no value is set here, -`centos-art.sh' script uses current file path to build the -related url that points to current file location inside repository -central server. -

-
-
`Language'
-

Two-letter language tag with optional subtags for the language of this -document. (e.g. `en-GB'). If no value is set here, -`centos-art.sh' script uses the current locale information as in -cli_getCurrentLocale function. -

-
-
`Keywords'
-

The topic of this document as comma-separated key words, prhases, or -classifications. If no value is set here, `centos-art.sh' script -uses file path to build -

-
-
`Coverage'
-

Extent or scope of this document. If no value is set here, -`centos-art.sh' script uses the string `The CentOS Project'. -

-
-
`Description'
-

Description about the document. If no value is set here, -`centos-art.sh' script uses uses empty value as default. -

-
-
`Contributors'
-

People that contributes in the creation/maintainance of the document. -If no value is set here, `centos-art.sh' script uses uses empty -value as default. -

-
- -

The `License' metadatum is not set as a choise, by now. It is -fixed Creative Common Attribution Share-Alike 3.0 License. This is done in order to -grant license consistency among all SVG files we manage inside CentOS -Artwork Repository. -

- - - -

2.74.2.2 Unused definitions

- -

Many of the no-longer-used gradients, patterns, and markers (more -precisely, those which you edited manually) remain in the -corresponding palettes and can be reused for new objects. However if -you want to optimize your document, use the `Vacuum Defs' command -in `File' menu. It will remove any gradients, patterns, or -markers which are not used by anything in the document, making the -file smaller. -

-

If you have one or two couple of files, removing unused definitions -using the graphical interface may be enough to you. In contrast, if -you have dozens or even houndreds of scalable vector graphics files to -maintain it is not a fun task to use the graphical interface to remove -unused definitions editing those files one by one. -

-

To remove unused definitions from several scalable vector graphics -files, the `centos-art.sh' script uses Inkscape command-line -interface, specifically with the `--vaccum-defs' option. -

- - -

2.74.3 Usage

- -
-
centos-art svg --update-metadata='path/to/dir'
-
centos-art svg --update-metadata='path/to/dir' --filter='regex'
-

Use these commands to update metadata information to `.svg' files -under `path/to/dir' directory. -

-
-
centos-art svg --vacuum-defs='path/to/dir'
-
centos-art svg --vacuum-defs='path/to/dir' --filter='regex'
-

Use these commands to remove unused definitions inside `.svg' -files under `path/to/dir' directory. -

-
- -

When you provide `--filter='regex'' argument, the list of files -to process is reduced as specified in `regex' regular expression. -Inside `centos-art.sh' script, the `regex' regular -expression is used in combination with find command to look -for files matching the regular expression path pattern. -

-
Warning

Warning

In order for `regex' regular expression to match -a file, the `regex' regular expresion must match the whole file -path not just the file name. -

- -

For example, if you want to match all `summary.svg' files inside -`path/to/dir', use the .+/summary regular expression. -Later, `centos-art.sh' script uses this value inside -^$REGEX\.svg$ expression in order to build the final regular -expression (i.e., ^.+/summary\.svg$) that is evaluated against -available file paths inside the list of files to process. -

-

Exceptionally, when you provide `--filter='regex'' in the way -that `regex', appended to `path/to/dir/' (i.e. -`path/to/dir/regex'), matches a regular file; the -`centos-art.sh' script uses the file matching as only file in the -list of files to process. -

2.75 The `trunk/Scripts/Bash/Cli/Functions/Verify' Directory

- - - -

2.75.1 Goals

- -

This section exists to organize files related to `centos-art.sh' -script `verify' functionality. The `verify' -functionality of `centos-art.sh' script helps you to verify the -workstation configuration you are planning to use as host for your -working copy of CentOS Artwork Repository. -

- - -

2.75.2 Description

- -

The first time you download CentOS Artwork Repository you need to -configure your workstation in order to use `centos-art.sh' -script. These preliminar configurations are based mainly on auxiliar -RPM packages installation, symbolic links creations, and environment -variables definitions. The `verify' functionality of -`centos-art.sh' script guides you through this preliminar -configuration process. -

-

If this is the first time you run `centos-art.sh' script, the -appropriate way to use its `verify' functionality is not using -the `centos-art.sh' script directly, but the absolute path to -centos-art.sh script instead (i.e., -`~/artwork/trunk/Scripts/Bash/centos-art.sh'). This is necessary -because `centos-art' symbolic link, under `~/bin/' -directory, has not been created yet. -

- - -

2.75.2.1 Packages

- -

Installation of auxiliar RPM packages provides the software required -to manipulate files inside the repository (e.g., image files, -documentation files, translation files, script files, etc.). Most of -RPM packages centos-art.sh script uses are shipped with -CentOS distribution, and can be installed from CentOS base repository. -The only exception is `inkscape', the package we use to -manipulate SVG files. The `inkscape' package is not inside -CentOS distribution so it needs to be installed from third party -repositories. -

-
info

Note

Configuration of third party repositories inside CentOS -distribution is described in CentOS wiki, specifically in the -following URL: -http://wiki.centos.org/AdditionalResources/Repositories -

- -

Before installing packages, the `centos-art.sh' script uses -sudo to request root privileges to execute yum -installation functionality. If your user isn't defined as a -privileged user--at least to run yum commands-- inside -`/etc/sudoers' configuration file, you will not be able to -perform package installation tasks as set in `centos-art.sh' -script `verify' functionality. -

-

Setting sudo privileges to users is an administrative task you have to -do by yourself. If you don't have experience with sudo -command, please read its man page running the command: man -sudo. This reading will be very useful, and with some practice, you -will be able to configure your users to have sudo -privileges. -

- - -

2.75.2.2 Links

- -

Creation of symbolic links helps us to alternate between different -implementations of `centos-art.sh' script-line (e.g., -`centos-art.sh', for Bash implementation; `centos-art.py', -for Python implementation; `centos-art.pl', for Perl -implementation; and so on for other implementations). The -`centos-art.sh' script-line definition takes place inside your -personal binary (`~/bin/') directory in order to make the script -implementation --the one that `centos-art' links to-- available -to PATH environment variable. -

-

Creation of symbolic links helps us to reuse components from repository -working copy. For example, color information files maintained inside -your working copy must never be duplicated inside program-specific -configuration directories that uses them in your workstation (e.g., -Gimp, Inkscape, etc.). Instead, a symbolic link must be created for -each one of them, from program-specific configuration directories to -files in the working copy. In this configuration, when someone -commits changes to color information files up to central repository, -they--the changes committed-- will be immediatly available to your -programs the next time you update your working copy --the place -inside your workstation those color information files are stored--. -

-

Creation of symbolic links helps us to make `centos-art.sh' -script functionalities available outside `trunk/' repository -directory structure, but at its same level in repository tree. This is -useful if you need to use the "render" functionality of -centos-art.sh under `branches/' repository directory -structure as you usually do inside `trunk/' repository directory -structure. As consequence of this configuration, automation scripts -cannot be branched under `branches/Scripts' directory structure. -

- - -

2.75.2.3 Environment variables

- -

Definition of environemnt variables helps us to set default values to -our user session life. The user session environment variable defintion -takes place in the user's `~/.bash_profile' file. The -`verify' functionality of `centos-art.sh' script doesn't -modify your `~/.bash_profile' file. -

-

The `verify' functionality of `centos-art.sh' script -evaluates the following environment variables: -

-
-
EDITOR
-

Default text editor. -

-

The `centos-art.sh' script uses default text EDITOR to edit -pre-commit subversion messages, translation files, configuration -files, script files, and similar text-based files. -

-

If EDITOR environment variable is not set, `centos-art.sh' -script uses `/usr/bin/vim' as default text editor. Otherwise, the -following values are recognized by `centos-art.sh' script: -

-
    -
  • `/usr/bin/vim' -
  • `/usr/bin/emacs' -
  • `/usr/bin/nano' -
- -

If no one of these values is set in EDITOR environment variable, -`centos-art.sh' uses `/usr/bin/vim' text editor by default. -

-
-
TEXTDOMAIN
-
-

Default domain used to retrieve translated messages. This variable is -set in `initFunctions.sh' and shouldn't be changed. -

-
-
TEXTDOMAINDIR
-
-

Default directory used to retrieve translated messages. This variable -is set in `initFunctions.sh' and shouldn't be changed. -

-
-
LANG
-
-

Default locale information. -

-

This variable is initially set in the configuration process of CentOS -distribution installer (i.e., Anaconda), specifically in the -`Language' step; or once installed using the -system-config-language tool. -

-

The `centos-art.sh' script uses the LANG environment -variable to know in which language the script messages are printed -out. -

-
-
TZ
-
-

Default time zone representation. -

-

This variable is initially set in the configuration process of CentOS -distribution installer (i.e., Anaconda), specifically in the -`Date and time' step; or once installed using the -system-config-date tool. -

-

The `centos-art.sh' script doesn't use the TZ environment -variable information at all. Instead, this variable is used by the -system shell to show the time information according to your phisical -location on planet Earth. -

-

Inside your computer, the time information is firstly set in the BIOS -clock (which may need correction), and later in the configuration -process of CentOS distribution installer (or later, by any of the -related configuration tools inside CentOS distribution). Generally, -setting time information is a straight-forward task and configuration -tools available do cover most relevant location. However, if you need -a time precision not provided by the configuration tools available -inside CentOS distribution then, using TZ variable may be -necessary. -

-
Convenction

Convenction

In order to keep changes syncronized between -central repository and its working copies: configure both repository -server and workstations (i.e., the place where each working copy is -set on) to use Coordinated Universal Time (UTC) as base time -representation. Later, correct the time information for your specific -location using time zone correction. -

- -

The format of TZ environment variable is described in -`tzset(3)' manual page. -

2.75.3 Usage

- -
-
centos-art verify --packages
-
-

Verify required packages your workstation needs in order to run the -`centos-art.sh' script correctly. If there are missing packages, -the `centos-art.sh' script asks you to confirm their -installation. When installing packages, the `centos-art.sh' -script uses the yum application in order to achieve the -task. -

-

In case all packages required by `centos-art.sh' script are -already installed in your workstation, the message `The required -packages are already installed.' is output for you to know. -

-
-
centos-art verify --links
-
-

Verify required links your workstation needs in order to run the -centos-art command correctly. If any required link is missing, the -centos-art.sh script asks you to confirm their installation. -To install required links, the centos-art.sh script uses the -ln command. -

-

In case all links required by `centos-art.sh' script are already -created in your workstation, the message `The required links are -already installed.' is output for you to know. -

-

In case a regular file exists with the same name of a required link, -the `centos-art.sh' script outputs the `Already exists as -regular file.' message when listing required links that will be -installed. Of course, as there is already a regular file where must be -a link, no link is created. In such cases the `centos-art.sh' -script will fall into a continue installation request for that missing -link. To end this continue request you can answer `No', or -remove the existent regular file to let `centos-art.sh' script -install the link on its place. -

-
-
centos-art verify --environment
-
centos-art verify --environment --filter='regex'
-
-

Output a brief description of environment variables used by -`centos-art.sh' script. -

-

If `--filter' option is provided, output is reduced as defined in -the `regex' regular expression value. If `--filter' option -is specified but `regex' value is not, the `centos-art.sh' -script outputs information as if `--filter' option had not been -provided at all. -

2.3 The `trunk' Directory

+ + + +

2.3.1 Goals

+ +

This directory implements the Subversion's trunk concept in a +trunk, branches, tags repository structure. +

+ + +

2.3.2 Description

+ +

The `trunk/' directory structure is the main development line +inside the CentOS Artwork Repository and organizes the following +sections: +

+
+
Identity
+

This section organizes image production in different formats and some +non-image formats like XHTML and text files, as well. This is the +perfect place to consolidate The CentOS Artwork SIG. If you are +interested in producing art works for The CentOS Project, this place +is for you. +

+

See section The `trunk/Identity' Directory, for more information. +

+
+
Manual
+

This section organizes the CentOS Artwork Repository Manual +(i.e., the documentation manual you're reading right now). If you are +interested on improving The CentOS Artwork Repository Manual, in this +place you'll find the Texinfo documentation structure you need to work +with. +

+

See section The `trunk/Manual' Directory, for more information. +

+
+
Scripts
+

This section organizes production of automation scripts specially +designed to automate most frequent tasks in the repository (e.g., +image rendition, documenting directory structures, translating +content, etc.). If you can't resist the idea of automating repeatable +tasks, then take a look here. +

+

See section The `trunk/Scripts' Directory, for more information. +

+
+
Locales
+

This section organizes production of translation messages for +Identity, Documentation and Scripts. This place +is perfect to consolidate The CentOS Translation SIG. If you +love translating, you'll find lot of messages waiting for you to +translate here. +

+

See section The `trunk/Locales' Directory, for more information. +

+
+ + + +

2.3.3 Usage

+ +

It seems to be no other use for this directory but to organize the +sections described above. +

+ + +

2.4 The `trunk/Identity' Directory

+ + + +

2.4.1 Goals

+ +

The `trunk/Identity' directory structure implements The +CentOS Project Corporate Identity. +

+ + +

2.4.2 Description

+ +

The CentOS Project corporate identity is the "persona" of the +organization known as The CentOS Project. The CentOS Project +corporate identity plays a significant role in the way the CentOS +Project, as organization, presents itself to both internal and +external stakeholders. In general terms, the CentOS Project corporate +visual identity expresses the values and ambitions of the CentOS +Project organization, its business, and its characteristics. +

+

The CentOS Project corporate identity provides visibility, +recognizability, reputation, structure and identification to The +CentOS Project organization by means of Corporate Design, +Corporate Communication, and Corporate Behaviour. +

+ + +

2.4.2.1 Corporate Design

+ +

The CentOS Project corporate design is applied to every single visual +manifestations The CentOS Project as organization wants to express its +existence. Examples of the most relevant visual manifestations inside +The CentOS Project are The CentOS Distribution, The +CentOS Web and The CentOS Stationery. +

+

The CentOS Project corporate design is organized in the following +work-lines: +

+
+
The CentOS Brand
+

The CentOS Brand is the name or trademark that connects the producer +with their products. In this case, the producer is The CentOS Project +and the products are The CentOS Project visual manifestations. +

+

See section The `trunk/Identity/Brands' Directory, for more information. +

+
+
The CentOS Colors
+
+

The CentOS Fonts provides the color information used along The CentOS +Project visual manifestations. +

+

See section The `trunk/Identity/Colors' Directory, for more information. +

+
The CentOS Fonts
+
+

The CentOS Fonts provides the typography information used along The +CentOS Project visual manifestations. +

+

See section The `trunk/Identity/Fonts' Directory, for more information. +

+
The CentOS Themes
+
+

The CentOS Themes provides structural information and visual style +information, as well, used along The CentOS Project visual +manifestations. +

+

See section The `trunk/Identity/Themes' Directory, for more information. +

+
+ + + +

2.4.2.2 Corporate Communication

+ +

The CentOS Project corporate communication is based on community +communication. In that sake, the following media are available for +corporate communication: +

+ + + + +

2.4.2.3 Corporate Behaviour

+ +

The CentOS Project corporate behaviour is based on community +behaviour. +

+ + +

2.4.2.4 Corporate Structure

+ +

The CentOS Project corporate structure is based on a monolithic +corporate visual identity structure. In this structure, we use one +unique name (The CentOS Brand) and one unique visual style (The CentOS +Theme) in all The CentOS Project visual manifestations. +

+

Inside a monolithic corporate visual identity structure, internal and +external stakeholders use to feel a strong sensation of uniformity, +orientation, and identification with the organization. No matter if +you are visiting web sites, using the distribution, or acting on +social events, the one unique name and one unique visual style +connects them all to say: Hey! we are all part of The CentOS +Project. +

+

Other corporate structures have been considered as well, but they +introduce visual contradictions we need to be aware of. In that sake, +lets describe the idea of: Producing one different visual style +for each major release of The CentOS Distribution. +

+

The CentOS Project maintains near to four different major releases of +The CentOS Distribution parallely in time and that fact makes one part +of The CentOS Project structural design, but just one part, not the +complete structural design. In order to produce the correct corporate +structure for The CentOS Project we need to concider all the visual +manifestations The CentOS Project is made of, not just one of them. +

+

If one different visual style is used for each major release of The +CentOS Distribution, which one of those different visual styles would +be used to cover the remaining visual manifestations The CentOS +Project is made of. Would we end up with four different visual styles, +one for each distribution? In that case, why The CentOS Distribution +we use shows one visual style, The CentOS Web sites another and The +CentOS Stationery even another completly different one? Isn't them +all part of the same project? +

+

Probably you be thinking, that's right, but The CentOS Brand connects +them all already, why would we need to join them up into the same +visual style too, isn't it more work to do, and harder to maintain? +

+

Harder to maintain, more work to do, it is probably. Specially when +you consider that The CentOS Project has proven stability and +consistency through time and that, certainly, didn't come through +swinging magical wangs or something but hardly working out to automate +tasks and so providing maintainance through time. Said that, we +consider that The CentOS Project visual structure should be consequent +with such stability and consistency tradition. It is true The CentOS +Brand does connect all the visual manifestations it is present on, but +that connection would be stronger if one unique visual style backups +it. In fact, whatever thing you do to strength the visual connection +among The CentOS Project visual manifestations would be very good in +favor of The CentOS Project recognition. +

+

Obviously, having just one visual style in all visual manifestations +for eternity would be a very boring thing and would give the idea of a +visually dead project. So, there is no problem on creating a brand new +visual style for each new major release of The CentOS Distribution, in +order to refresh The CentOS Distribution visual style; the problem +does is in not propagating the brand new visual style created for the +new release of CentOS Distribution to all other visual manifestations +The CentOS Project is made of, in a way The CentOS Project could be +recognized no matter what visual manifestation be in front of us. Such +lack of uniformity is what introduces the visual contradition we are +precisely trying to solve by mean of themes production in the CentOS +Artwork Repository. +

+ + +

2.4.3 Usage

+ +

The `trunk/' directory structure is organized in +renderable and non-renderable directories. Generally, +renderable directories contain two non-renderable directories inside, +one to store design templates (the `Tpl/' directory), and other +to store the content produced (the `Img/' directory). +

+

In order to produce content inside rendereble directories, you can use +the following command: +

+
centos-art render trunk/Identity/Path/To/Dir
+
+
Warning

Warning

If the centos-art command-line +is not found in your workstation, it is probably because you haven't +prepared it for using The CentOS Artwork Repository yet. +See section The `trunk/Scripts/Bash/Cli/Functions/Verify' Directory, for more +information. +

+ +

This command takes one design template from the template directory and +creates an instance of it in order to apply translation messages on +it, if any. Later, using the design template instance, the command +renders the final content based on whether the design template +instance is a SVG file or a Docbook file. If the design template +instace is a SVG file, the final content produced is a PNG image. On +the other hand, if the design template instance is a Docbook file, the +final content produced is a XHTML file. Final content is stored in the +image directory using the design template directory paths as referece. +The rendition flow described so far is known as the +base-rendition flow. +

+

Besides the base-rendition flow, the centos-art provides the +post-rendition and last-rendition flows. The +post-rendition flow is applied to files produced as result of +base-rendition flow under the same directory structure. For example, +you can use post-rendition action to convert the PNG base output into +different outputs (e.g., JPG, PDF, etc.) before passing to process the +next file in the same directory structure. The last-rendition flow is +applied to all files produced as result of both base-rendition and +post-rendition flows in the same directory structure, just before +passing to process a different directory structure. For example, the +`Preview.png' image from Ksplash component is made of three +images. In order to build the `Preview.png' image through +centos-art we need to wait for all the three images the +`Preview.png' image is made of to be rendered, so we can combine +them all together into just one image (i.e., the `Preview.png' +image). This is something we can't do using post-rendition flow. +

+

Inside `trunk/Identity' directory structure, you can find that +base-rendition, post-rendition and last-rendition flows can be +combined to build directory-specific rendition. The +directory-specific rendition exists to automatically process specific +renderable directories in very specific ways. Using directory-specific +rendition speeds up production of different components like Syslinux, +Grub, Gdm, Kdm and Ksplash that require intermediate formats or even +several independent files, in order to reach its final construction. +Directory-specific rendition is a way to programmatically describe how +specific art works are built in and organized inside The CentOS +Artwork Repository. Such descriptions have been added to +centos-art command-line to let you produce them all with +just one single command, as fast as your machine can be able to handle +it. +

+

See section The `trunk/Scripts/Bash/Cli/Functions/Identity' Directory, for more +information about the identity functionality of +centos-art command-line interface. +

2.7 The `trunk/Identity/Fonts' Directory

+ + + +

2.7.1 Goals

+ +

This section exists to organize digital typographies used by the +CentOS project. +

+ + +

2.7.2 Description

+ + + +

2.7.3 Usage

+ +

The CentOS corporate identity is attached to `DejaVu LGC' +font-family. Whatever artwork you design for CentOS project, that +requires typography usage, must be done using `DejaVu LGC' +font-family. +

+
+
Recommendation-1:
+
+

For screen desings (e.g., anything that final destination will never +be printed on paper or any medium outside computer screens) use +`DejaVu LGC Sans' font-family. +

+
+
Recommendation-2:
+
+

For non-screen designs (e.g., anything that final desition will be +printed on paper or any other medium outside computer screens) use +`DejaVu LGC Serif' font-family. As convenction files described in +this rule are stored under `Stationery' directories. +

+
+ +

The only execption for the two recommendations above is the typography +used inside CentOS logo. The CentOS logo is the main visual +representation of the CentOS project so the typography used in it must +be the same always, no matter where it be shown. It also has to be +clear enough to dismiss any confussion between similar typefaces +(e.g., the number one (1) sometimes is confuesed with the letter +`el' (l) or letter `ai' (i)). +

+

As CentOS logo typography convenction, the word `CentOS' uses +`Denmark' typography as base, both for the word `CentOS' and +the phrase `Community Enterprise Operating System'. The phrase +size of CentOS logo is half the size in poits the word `CentOS' +has and it below `CentOS' word and aligned with it on the left. +The distance between `CentOS' word and phrase `Community +Enterprise Operating System' have the size in points the phrase has. +

+

When the CentOS release brand is built, use `Denmark' typography +for the release number. The release number size is two times larger +(in height) than default `CentOS' word. The separation between +release number and `CentOS' word is twice the size in points of +separation between `CentOS' word and phrase `Community +Enterprise Operating System'. +

+

Another component inside CentOS logo is the trademark symbol (TM). +This symbol specifies that the CentOS logo must be consider a product +brand, even it is not a registered one. The trademark symbol uses +DejaVu LGC Sans Regular typography. The trademark symbol is aligned +right-top on the outter side of `CentOS' word. The trademark +symbol must not exceed haf the distance, in points, between +`CentOS' word and the release number on its right. +

+

It would be very convenient for the CentOS Project and its community +to to make a registered trademark (®) of CentOS logo. To make a +register trademark of CentOS Logo prevents legal complications in the +market place of brands. It grants the consistency, through time, of +CentOS project corporate visual identity. +

+

The information about trademarks and corporate identity +is my personal interpretation of +http://en.wikipedia.org/Corporate_identity and +http://en.wikipedia.org/Trademark description. If you have +practical experiences with these affairs, please serve yourself to +improve this section with your reasons. +

1.1 History

+ +

This section records noteworthy changes of CentOS Artwork Repository. +

+ +

2008

+ +

The CentOS Artwork Repository started at CentOS Developers mailing +list (centos-devel@centos.org) during a discussion about how +to automate the slide images of Anaconda. In such discussion, Ralph +Angenendt rose up his hand to ask: Do you have something to show? +

+

To answer the question, Alain Reguera Delgado posted a bash script to +produce slide images in different languages --together with the +proposition of creating a Subversion centralized repository where +translations and image production could be distributed inside The +CentOS Community--. +

+

Karanbirn Sighn considered the idea intresting and provides the +infrastructure to support the effort. This way both the CentOS Artwork +SIG and the CentOS Artwork Repository were created. +

+ + +

Once the CentOS Artwork Repository was available, Alain Reguera +Delagdo uploaded the bash script for rendering Anaconda slides and +Ralph Angenendt documented the script very well. +

+

Once the rendition script and its documentation were available online, +translators started to download working copies of CentOS Artwork +Repository to produce slide images in their own languages. +

+ +

2009

+ +

The rendition script is designed to take one SVG file, apply one SED +file with replacement command inside to produce one SVG translated +instance that is used to produce one translated PNG image by means of +Inkscape program. The rendition script was named render.sh +and it is copied to each directory structure that requires such +process to produce images. +

+

Furthermore, functionalies are centralized in a common placed and +linked from different directory structures. There is no need to have +the same code in different directory structures if can have it in just +one place and then create links to it. +

+

Start to implement concepts about corporate identity. As referece it +is used Wikipedia (http://en.wikipedia.org/Corporate_identity) +and the book Corporate Identity by Wally Olins (1989). The main +goal of render.sh becomes to: automate production of a +monolithic corporate visual identity structure based on The CentOS +Mission and The CentOS Release Schema. +

+

Around March, Alain Reguera Delgado is out of Internet for an +undefined amount of time, but continues developing the idea of CentOS +Artwork Repository and the rendition script off-line. +

+

Most of the work I propose from this time on is my own responsability. +I keep myself thinking to be part of the CentOS Artwork SIG and in +that sake, I use the personal pronoun we to refer what I do as +part of the group hoping someday to share this work with you again and +improve it together. +

+

The CentOS Artwork Repository documentation starts to take form in +LaTeX format. +

+ +

2010

+ +

The render.sh is removed from the repository directory +structures and the centos-art.sh script is used instead. The +centos-art.sh is created to be a command-line interface that +automate most frequent tasks inside the repository and can be called +anywhere inside the repository or outside it; whenever it points to a +directory structure inside the repository. At the very first moments +of using centos-art.sh command-line, it used to have the +following using form: +

+
centos-art function --action=path/to/dir
+
+

Inside the rendition script, functionalities started to get identified +and separated one another. For example, when images are rendered, +there is no need to load manual functionality. There are now common +functionalities and specific functionalities. Common functionalities +are loaded when the script is initiated and are available to specific +functionalities. +

+

Start using getopt to handle command-line options. +

+

The repository directory structure is optimized to continue +implementing corporate identity concepts and the centos-art +command-line. +

+ +

2011

+ +

The `trunk/Translation' directory structure is removed. The +`trunk/Locales' directory structure is used instead to store locale +information. +

+

The `.sed' translation files are no longer used, scalable vector +graphics are used instead. Translation messages take place by means +of xml2po and gettext. With xml2po translatable strings are retrived +from `.svg' files and stored inside gettext `.pot' and `.po' files for +translators to edit. Finally, xml2po is used again to build the +temporal design model translated instance which the final `.png' image +is built from. +

+

Inside centos-art.sh, update command-line arguments and +options parsing. Keep using getopt to parse options passed +in the command-line, but change the way centos-art.sh is +called from. The following form is used: +

+
centos-art function path/to/dir --options
+
+

Start using verbs to name the centos-art.sh functionalities. +

+

Organize centos-art.sh functionalities in "administrative" +functions and "productive" functions. Administrative functions +cover actions like: copying, deleting and renaming directory +structures. Also, preparing your workstation for using +centos-art command-line, make backups of the distribution +theme currently installed, installing themes created inside The +CentOS Artwork repository and restoring themes from backup. On the +other hand, productive functions cover actions like: content +rendition, content localization, content documentation and content +maintainance. +

2.16 The `trunk/Identity/Models/Tpl/Promo/Web' Directory

+ + + +

2.16.1 Goals

+ +

Organize scalable vector graphics (svg) to help describe the CentOS +web environment. +

+ + +

2.16.2 The CentOS web environment

+ +

Inside CentOS corporate identity, the CentOS web environment is +considered a promotion component. The CentOS web environment is formed +by a central web application --to cover base needs (e.g., per-major +release information like release notes, lifetime, downloads, +documentation, support, security advisories, bugs, etc.)-- and many +different free web applications --to cover specific needs (e.g., +wiki, mailing lists, etc.)--. +

+

The CentOS web environment is addressed to solve the following issues: +

+ + +

The CentOS project is attached to a monolithic corporate visual +identity (see section The `trunk/Identity' Directory), where all visual manifestations +have one unique name and one unique visual style. This way, the CentOS +web environment has one unique name (the CentOS brand) and one unique +visual style (the CentOS default theme) for all its visual +manifestations, the web applications in this case. +

+

Since a maintainance point of view, achiving the one unique visual +style inside CentOS web environment is not a simple task. The CentOS +web environment is built upon many different web applications which +have different visual styles and different internal ways to customize +their own visual styles. For example: MoinMoin, the web application +used to support the CentOS wiki (http://wiki.centos.org/) is +highly customizable but Mailman (in its 2.x.x serie), the web +application used to support the CentOS mailing list, doesn't +support(1) a customization system that separates +presentation from logic, similar to that used by MoinMoin. +

+

This visual style diversity complicates our goal of one unique visual +style for all web applications. So, if we want one unique visual style +for all web applications used, it is innevitable to modify the web +applications in order to implement the CentOS one unique visual style +customization in them. Direct modification of upstream applications is +not convenient because upstream applications come with their one +visual style and administrators take the risk of loosing all +customization changes the next time the application be updated (since +not all upstream web applications, used in CentOS web environment, +separate presentation from logic). +

+

To solve the "one unique visual style" issue, installation and +actualization of web applications --used inside CentOS web +environment-- need to be independent from upstream web applications +development line; in a way that CentOS web environment administrators +can install and update web applications freely without risk of loosing +the one unique visual style customization changes. +

+

At the surface of this issue we can see the need of one specific yum +repository to store CentOS web environment customized web applications. +

+ + + +

2.16.2.2 Design model (with ads)

+ + + +

2.16.2.3 HTML definitions

+ + + +

2.16.2.4 Controlling visual style

+ +

Inside CentOS web environment, the visual style is controlled by the +following compenents: +

+
+
Webenv header background
+
trunk/Identity/Themes/Motifs/$THEME/Backgrounds/Img/1024x250.png
+
+
+
CSS definitions
+
trunk/Identity/Themes/Models/Default/Promo/Web/CSS/stylesheet.css
+
+
+ + + +

2.16.2.5 Producing visual style

+ +

The visual style of CentOS web environment is defined in the following +files: +

+
trunk/Identity/Themes/Motifs/$THEME/Backgrounds/Xcf/1024x250.xcf
+trunk/Identity/Themes/Motifs/$THEME/Backgrounds/Img/1024x250.png
+trunk/Identity/Themes/Motifs/$THEME/Backgrounds/Img/1024x250-bg.png
+trunk/Identity/Themes/Motifs/$THEME/Backgrounds/Tpl/1024x250.svg
+
+

As graphic designer you use `1024x250.xcf' file to produce +`1024x250-bg.png' file. Later, inside `1024x250.svg' file, +you use the `1024x250-bg.png' file as background layer to draw +your vectorial design. When you consider you artwork ready, use the +centos-art.sh script, as described below, to produce the +visual style controller images of CentOS web environment. +

+
centos-art render --entry=trunk/Identity/Themes/Motifs/$THEME/Backgrounds --filter='1024x250'
+
+

Once you have rendered required image files, changing the visual style +of CentOS web environment is a matter of replacing old image files +with new ones, inside webenv repository file system structure. The +visual style changes will take effect the next time customization line +of CentOS web applications be packaged, uploded, and installed from +[webenv] or [webenv-test] repositories. +

+ + +

2.16.2.6 Navigation

+ +

Inside CentOS web environment, the one-step navegation between web +applications is addressed using the web environment navigation bar. +The web environment navigation bar contains links to main applications +and is always visible no matter where you are inside the web +environment. +

+ + +

2.16.2.7 Development and release cycle

+ +

The CentOS web environment development and relase cycle is described +below: +

+
+
Download
+
+

The first action is download the source code of web applications we +want to use inside CentOS web environment. +

+
Important

Important

The source location from which web application are +downloaded is very important. Use SRPMs from CentOS [base] +and [updates] repositories as first choise, and third party +repositories (e.g. RPMForge, EPEL, etc.) as last resource. +

+ +
+
Prepare
+
+

Once web application source code has been downloaded, our duty is +organize its files inside `webenv' version controlled repository. +

+

When preparing the structure keep in mind that different web +applications have different visual styles, and also different ways to +implement it. A convenient way to organize the file system structure +would be create one development line for each web application we use +inside CentOS web environment. For example, consider the following +file system structure: +

+
https://projects.centos.org/svn/webenv/trunk/
+|-- WebApp1/
+|   |-- Sources/
+|   |   `-- webapp1-0.0.1/
+|   |-- Rpms/
+|   |   `-- webapp1-0.0.1.rpm
+|   |-- Srpms/
+|   |   `-- webapp1-0.0.1.srpm
+|   `-- Specs/
+|       `-- webapp1-0.0.1.spec
+|-- WebApp2/
+`-- WebAppN/
+
+
+
Customize
+
+

Once web applications have been organized inside the version +controlled repository file system, use subversion to create the CentOS +customization development line of web applications source code. For +example, using the above file system structure, you can create the +customization development line of `webapp1-0.0.1/' with the +following command: +

+
svn cp trunk/WebApp1/Sources/webapp1-0.0.1 trunk/WebApp1/Sources/webapp1-0.0.1-webenv
+
+

The command above creates the following structure: +

+
https://projects.centos.org/svn/webenv/trunk/
+|-- WebApp1/
+|   |-- Sources/
+|   |   |-- webapp1-0.0.1/
+|   |   `-- webapp1-0.0.1-webenv/
+|   |-- Rpms/
+|   |   `-- webapp1-0.0.1.rpm
+|   |-- Srpms/
+|   |   `-- webapp1-0.0.1.srpm
+|   `-- Specs/
+|       `-- webapp1-0.0.1.spec
+|-- WebApp2/
+`-- WebAppN/
+
+

In the above structure, the `webapp1-0.0.1-webenv/' directory is +the place where you customize the visual style of +`webapp1-0.0.1/' web application. +

+
Info

Tip

Use the diff command of Subversion between +CentOS customization and upstream development lines to know what you +are changing exactly. +

+ +
+
Build packages
+
+

When web application has been customized, build the web application +RPM and SRPM using the source location with `-webenv' prefix. +

+
https://projects.centos.org/svn/webenv/trunk/
+|-- WebApp1/
+|   |-- Sources/
+|   |   |-- webapp1-0.0.1/
+|   |   `-- webapp1-0.0.1-webenv/
+|   |-- Rpms/
+|   |   |-- webapp1-0.0.1.rpm
+|   |   `-- webapp1-0.0.1-webenv.rpm
+|   |-- Srpms/
+|   |   |-- webapp1-0.0.1.srpm
+|   |   `-- webapp1-0.0.1-webenv.srpm
+|   `-- Specs/
+|       |-- webapp1-0.0.1.spec
+|       `-- webapp1-0.0.1-webenv.spec
+|-- WebApp2/
+`-- WebAppN/
+
+
+
Release for testing
+
+

When the customized web application has been packaged, make packages +available for testing and quality assurance. This can be achives using +a [webenv-test] yum repository. +

+
info

Note

The [webenv-test] repository is not shipped inside +CentOS distribution default yum configuraiton. In order to use +[webenv-test] repository you need to configure it first. +

+ +

If some problem is found to install/update/use the customized version +of web application, the problem is notified somewhere (a bugtracker +maybe) and the customization face is repated in order to fix the +problem. To release the new package add a number after `-webenv' +prefix. For example, if some problem is found in +`webapp1-0.0.1-webenv.rpm', when it be fixed the new package will +be named `webapp1-0.0.1-webenv-1.rpm'. If a problem is found in +`webapp1-0.0.1-webenv-1.rpm', when it be fixed the new package +will be named `webapp1-0.0.1-webenv-2.rpm', and so on. +

+

The "customization -- release for testing" process is repeated +until CentOS quality assurance team considers the package is ready for +production. +

+
+
Release for production
+
+

When customized web application packages are considered ready for +production they are moved from [webenv-test] to [webenv] repository. +This action is commited by CentOS quality assurance team. +

+
info

Note

The [webenv] repository is not shipped inside CentOS +distribution default yum configuraiton. In order to use [webenv] +repository you need to configure it first. +

+
+
+ + + +

2.20.1 Goals

+ + + + + +

2.20.2 Description

+ +

Theme models let you modeling characteristics (e.g., dimensions, +translation markers, position of each element on the display area, +etc.) common to all themes. Theme models let you reduce the time +needed when propagating artistic motifs to different visual +manifestations. +

+

Theme models serves as a central pool of design templates for themes +to use. This way you can produce themes with different artistic motifs +but same characteristics. +

+ + +

2.20.3 Usage

+ +

Inside the framework location above, you find theme models organized +by name. You can add your own theme models to the structure by adding +a directory to the list. By default you have the `See section Default,' and `See section Alternative,' ready-to-use theme models. +

2.22 The `trunk/Identity/Themes/Models/Default' Directory

+ + + +

2.22.1 Goals

+ +

Default Design Models for CentOS Themes provide design models for the +following components: +

+
+
Distribution
+

Design models for CentOS Distribution (e.g., Anaconda, Firstboot, Gdm, +Grub, Gsplash, Kdm, Ksplash, Rhgb and Syslinux, etc.). +See section The `trunk/Identity/Themes/Models/Default/Distro' Directory, for +more information. +

+
+
Concept
+

Design models to illustrate Artistic Motifs Concepts. +See section The `trunk/Identity/Themes/Models/Default/Concept' Directory, for +more information. +

+
+
Promotion
+

Design models for CentOS Promotion stuff (e.g., installation media, +posters, etc.). See section The `trunk/Identity/Themes/Models/Default/Promo' Directory, for more information. +

+
+ + + +

2.22.2 Description

+ +

This directory implements the concept of Default Design Models +for CentOS Themes. Default Design Models for CentOS Themes provide +the common structural information (e.g., image dimensions, translation +markers, trademark position, etc.) the centos-art script +uses to produce images when no other design model is specified. +

+

Deisgn models in this directory do use the CentOS Release +Brand. The CentOS Release Brand is a combination of both The CentOS +Type and The CentOS Release Schema used to illustrate the major +release of CentOS Distribution the image produced belongs to. +See section The `trunk/Identity/Models/Tpl/Brands' Directory, for more +information. +

+ + +

2.22.3 Usage

+ +

The CentOS Project maintains near to four different major releases of +CentOS Distribution. Each major release of CentOS Distribution has +internal differences that make them unique and, at the same time, each +CentOS Distribution individually is tagged into the one unique visual +manifestation (i.e., Distribution). So, how could we implement the +monolithic visual structure in one visual manifestation that has +internal difference? +

+

To answer this question we broke the question in two parts and later +combined the resultant answers to build a possible solution. +

+
+
How to remark the internal differences visually?
+
+

Merge both The CentOS Project Release Schema into The CentOS Project +Trademark to build The CentOS Project Release Trademark. The CentOS +Project Release Trademark remarks two things: first, it remarks the +image is from The CentOS Project and second, it remarks which major +release of CentOS Distribution does the image belongs to. +See section The `trunk/Identity/Models/Tpl/Brands' Directory, for more +information on how to develop and improve The CentOS Project Brand. +

+
+
How to remark the visual resemblance?
+
+

Use a common artistic motifs as background for all CentOS Distribution +images. See section The `trunk/Identity/Themes/Motifs' Directory, for more +information. +

+
+
So, combining answers above, we could conclude that:
+
+

In order to implement the CentOS Monolithic Visual Structure on CentOS +Distribution visual manifestations, a CentOS Release Trademark and a +background information based on one unique artistic motif should be +used in all remarkable images The CentOS Distribution visual +manifestation is made of. +

+
+ +
Important

Important

Remarking the CentOS Release Schema inside each +major release of CentOS Distribution --or similar visual +manifestations-- takes high attention inside The CentOS +Project corporate visual identity. It should be very clear for +everyone which major release of CentOS Distribution is being used. +

+ + +

2.24.2 Description

+ +

The CentOS Distribution visual style is controlled by image files. +These image files are packaged inside The CentOS Distribution and made +visible once such packages are installed and executed. The way to go +for changing The CentOS Distribution visual style is changing all +those image files to add the desired visual style first and later, +repackage them to make them available inside the final iso files of +CentOS Distribution. +

+ + +

2.24.3 Usage

+ +

This directory provides organizationl structure to store default +design models for CentOS Themes of CentOS Distribution and so it +should be considered to be used. +

+

When a new component is added to CentOS Distribution, this is the +directory you need to go for specifying design models for image files +inside such component. +

+

The procedure to follow is creatig a directory for each component +using its very same name (e.g., the directory `Anaconda' stores +image files for Anaconda component, the installer program). Inside the +directory, you need to create one scalable vector graphic for each +image file inside the component you want to produce images for. This, +in order to set image dimensions, image file-name, position of +trademarks in the final image, translation markers and whatever common +information you need to have specified in them when rendered by +centos-art script. +

+

Sometimes, between major releases, image files inside packages can be +added, removed or just change their names. In order to describe such +image files variations, the design models directory structure is +organized in the same way the file variations are introduced (i.e., +through The CentOS Project Release Schema). So, each major release of +CentOS Distribution does have its own design model directory structure +in this directory. +

+

When a whole package is removed from one or all CentOS Distribution +major releases, the design models directory structure releated to it +is no longer used. However it could be very useful for historical +reasons. Also, someone could feel motivated enough to keep himself +documenting it or supporting it for whatever reason. +

1.3 Copying Conditions

+ +

Inside the CentOS Artwork Repository you can find content branded by +The CentOS Project and content not branded at all. Contents branded by +The CentOS Project contain either The CentOS Trademark, The CentOS +Logo or The CentOS Symbol. Content branded by The CentOS Project +cannot be redistributed without previous conversation with The CentOS +Project. However, you can study and modify both content branded by +The CentOS Project and content not branded at all in the sake of +proposing improvements to The CentOS Project corporate visual +identity. +

+

If you are using the CentOS Artwork Repository for producing your own +corporate visual identity, you should remove all The CentOS Trademarks +from your contents and rename the repository to something other than +CentOS Artwork Repository. +

+

The CentOS Artwork Repository organizes files in a very specific way +to implement The CentOS Project corporate visual identity. This very +specific organization of files is part of centos-art.sh +script, a bash script that automates most of the frequent tasks inside +the repository. +

+ + +

1.3.1 The centos-art.sh script

+ +

The centos-art.sh script and the organization of files it +needs to work are not in the public domain; they are copyrighted and +there are restrictions on their distribution, but these restrictions +are designed to permit everything that a good cooperating citizen +would want to do. What is not allowed is to try to prevent others +from further sharing any version of this program that they might get +from you. +

+

Specifically, we want to make sure that you have the right to give +away copies of centos-art.sh script, that you receive source +code or else can get it if you want it, that you can change this +program or use pieces of it in new free programs, and that you know +you can do these things. +

+

To make sure that everyone has such rights, we have to forbid you to +deprive anyone else of these rights. For example, if you distribute +copies of the centos-art.sh script, you must give the +recipients all the rights that you have. You must make sure that +they, too, receive or can get the source code. And you must tell them +their rights. +

+

Also, for our own protection, we must make certain that everyone finds +out that there is no warranty for the centos-art.sh script. +If this program is modified by someone else and passed on, we want +their recipients to know that what they have is not what we +distributed, so that any problems introduced by others will not +reflect on our reputation. +

+

The precise conditions of the license for the centos-art.sh +script are found in the General Public Licenses that accompany it (see +`trunk/COPYING' file). This manual specifically is covered by +the GNU Free Documentation License. +

+ + + + + +

2.36.2 Description

+ +

The artistic motif of theme is a graphic design component that +provides the visual style of themes, it is used as pattern to connect +all visual manifestations inside one unique theme. +

+

Artistic motifs are based on conceptual ideas. Conceptual ideas bring +the motivation, they are fuel for the engines of human imagination. +Good conceptual ideas may produce good motivation to produce almost +anything, and art works don't escape from it. +

+
+
`TreeFlower'
+

CentOS like trees, has roots, trunk, branches, leaves and flowers. Day +by day they work together in freedom, ruled by the laws of nature and +open standards, to show the beauty of its existence. +

+
`Modern'
+

Modern, squares and circles flowing up. +

+
+ +

If you have new conceptual ideas for CentOS, then you can say that you +want to create a new artistic motif for CentOS. To create a new +artistic motif you need to create a directory under +`Identity/Themes/Motifs/' using a name coherent with your +conceptual idea. That name will be the name of your artistic motif. If +possible, when creating new conceptual ideas for CentOS, think about +what CentOS means for you, what does it makes you feel, take your +time, think deep, and share; you can improve the idea as time goes on. +

+

Once you have defined a name for your theme, you need to create the +motif structure of your theme. The motif structure is the basic +direcotry structure you'll use to work your ideas. Here is where you +organize your graphic design projects. +

+

To add a new motif structure to CentOS Artwork Repository, you need to +use the centos-art command line in the +`Identity/Themes/Motifs/' directory as described below: +

+
 
centos-art add --motif=ThemeName
+
+

The previous command will create the basic structure of themes for +you. The basic structure produced by centos-art command is +illustrated in the following figure: +

+
 
trunk/Identity/Themes/Motifs/$ThemeName/
+|-- Backgrounds
+|   |-- Img
+|   `-- Tpl
+|-- Info
+|   |-- Img
+|   `-- Tpl
+|-- Palettes
+`-- Screenshots

2.37 The `trunk/Identity/Themes/Motifs/Flame' Directory

+ + + +

2.37.1 Goals

+ +

This section describes the steps we followed to construct the +Flame artistic motif. This section may be useful for anyone +interested in reproducing the Flame artistic motif, or in +creating new artistic motifs for The CentOS Project corporate visual +identity (see section The `trunk/Identity' Directory). +

+ + +

2.37.2 Description

+ +

The Flame artistic motif was built using the flame filter of +Gimp 2.2 in CentOS 5.5. +

+

The flame filter of Gimp can produce stunning, randomly generated +fractal patterns. The flame filter of Gimp gives us a great oportunity +to reduce the time used to produce new artistic motifs, because of its +"randomly generated" nature. Once the artistic motif be created, it +is propagated through all visual manifestations of CentOS Project +corporate visual identity using the `centos-art.sh' script +(see section The `trunk/Scripts/Bash' Directory) inside the CentOS Artwork Repository. +

+

To set the time intervals between each new visual style production, we +could reuse the CentOS distribution major release schema. I.e., we +could produce a new visual style, every two years, based on a new +"randomly generated" flame pattern, and publish the whole corporate +visual identity (i.e., distribution stuff, promotion stuff, websites +stuff, etc.) with the new major release of CentOS distribution all +together at once. +

+

Producing a new visual style is not one day's task. Once we have +defined the artistic motif, we need to propagate it through all visual +manifestations of The CentOS Project corporate visual identity. When +we say that we could produce one new visual style every two years we +really mean: to work two years long in order to propagate a new visual +style to all visual manifestations of The CentOS Project corporate +visual identity. +

+

Obviously, in order to propagate one visual style to all different +visual manifestations of The CentOS Project corporate visual identity, +we need first to know which the visual manifestations are. To define +which visual manifestations are inside The CentOS Project corporate +visual identity is one of the goals the CentOS Artwork Repository and +this documentation manual are both aimed to satisfy. +

+

Once we define which the visual manifestation are, it is possible to +define how to produce them, and this way, organize the automation +process. Such automation process is one of the goals of +`centos-art.sh' script. +

+

With the combination of both CentOS Artwork Repository and +`centos-art.sh' scripts we define work lines where translators, +programmers, and graphic designers work together to distribute and +reduce the amount of time employed to produce The CentOS Project +monolithic corporate identity. +

+

From a monolithic corporate visual identity point of view, notice that +we are producing a new visual style for the same theme (i.e., +Flame). It would be another flame design but still a flame +design. This idea is very important to be aware of, because we are +somehow "refreshing" the theme, not changing it at all. +

+

This way, as we are "refreshing" the theme, we still keep oursleves +inside the monolithic conception we are trying to be attached to +(i.e., one unique name, and one unique visual style for all visual +manifestations). +

+

Producing artistic motifs is a creative process that may consume long +time, specially for people without experienced knowledge on graphic +design land. Using "randomly generated" conception to produce +artistic motifs could be, practically, a way for anyone to follow in +order to produce maintainable artistic motifs in few steps. +

+

Due to the "randomly generated" nature of Flame filter, we find that +Flame pattern is not always the same when we use Flame +filter interface. +

+

Using the same pattern design for each visual manifestation is +essential in order to maintain the visual connection among all visual +manifestations inside the same theme. Occasionally, we may introduce +pattern variations in opacity, size, or even position but never change +the pattern design itself, nor the color information used by images +considered part of the same theme. +

+
Important

Important

+When we design background images, which are considered part of the +same theme, it is essential to use the same design pattern always. +This is what makes theme images to be visually connected among +themeselves, and so, the reason we use to define the word "theme" +as: a set of images visually connected among themeselves. +

+ +

In order for us to reproduce the same flame pattern always, +Flame filter interface provides the `Save' and `Open' +options. The `Save' option brings up a file save dialog that +allows you to save the current Flame settings for the plug-in, so that +you can recreate them later. The `Open' option brings up a file +selector that allows you to open a previously saved Flame settings +file. +

+

The Flame settings we used in our example are saved in the file: +

+
trunk/Identity/Themes/Motifs/Flame/Backgrounds/Xcf/800x600.xcf-flame.def
+
+ + +

2.37.3 Construction

+ + + +

2.37.3.1 Step 1: Set image size

+ +

Create an empty image and fill the `Background' layer with black +(000000) color. Image dimensions depend on the final +destination you plan to use the image for. For the sake of our +construction example we used an image of 640x480 pixels and 300 pixels +per inch (ppi). +

+ + +

2.37.3.2 Step 2: Add base color and pattern information

+ +

Create a new layer named `Base', place it over `Background' +layer and fill it with the base color (7800ff) you want to have +your background image set in. Add a mask to `Base' layer using +radial gradient and blur it. You may need to repeat this step more +than once in order to achieve a confortable black radial degradation +on the right side of your design. +

+

Duplicate `Base' layer and name it `Paper'. Place +`Paper' layer over `Base' layer. Remove content of +`Paper' layer and fill it with `Paper (100x100)' pattern. +Once you've done with black radial degradation, reduce the +`Paper' layer opacity to 20%. +

+

Notice that when we duplicate one layer, the mask information related +to layer is preserved from previous to next layer. This saves us some +of the time required to produce different layers with the same mask +information on them. +

+

Duplicate `Paper' layer and rename it `Stripes'. Remove +paper pattern from `Stripes' layer. Fill `Stripes' layer +with `Stripes (48x48)' pattern and reduce the `Stripes' +layer opacity to 15%. +

+ + +

2.37.3.3 Step 3: Add flame motif

+ +

Create a new layer named `Flame'. Set the foreground +(003cff) and background (0084ff) colors to the gradient +you want to build the flame motif. +

+

To build flame motif, use the flame filter (`Filters > Render > +Nature > Flame...') on `Flame' layer. We used a layer mask, with +a radial gradient on it to control the boundaries of flame motif on +`Flame' layer. +

+

Duplicate `Flame' layer and rename it `Flame Blur'. Place `Flame +Blur' below `Flame' layer. Apply Gussian blur filter +(`Filters > Blur > Gussian Blur...') until reaching the desiered +effect. +

+

The opacity value, in `Flame' layers, may vary from one image to +another based on the place the image will be finally placed on. For +example, images used as desktop background have the `Flame' layer +opacity set at 100% but `Flame Blur' is set to 70%. However, you +may find that background images used in anaconda progress slides have +opacity reduced differently, in order to reduce brightness in a way +that texts could look clean and readable over it. +

+ + +

2.37.3.4 Step 4: Add foreground color

+ +

Create a new layer named `Color', place it on top of all visible +layers and fill it with plain color (4c005a). Reduce +`Color' layer opacity to 20%. You can use the `Color' layer +to control the right side color information you want to produce the +image for. +

+

Duplicate `Flame' layer and create a new layer named +`Color#1'. Place `Color#1' layer on top of layer named +`Color'. Remove the mask information from `Color#1' layer +and recreate a new one using an inverted alpha channel as reference. +Remove `Color#1' layer content and fill it back with plain black +(000000) color. Reduce `Color#1' opacity to 20%. In this +step we created a mask to protect the flame artistic motif from black +color, so when we decrement or increment the opacity of layer, the +flame artistic motif wouldn't be affected, just the environment +suround it. +

+

When you set color information, remember that the same artistic motif +needs to be indexed to 14 and 16 colors, in order to produce Grub and +Syslinux visual manifestations respectively. Using many different +colors in the artistic motif may reduce the possibility of your design +to fix all different situations in. Likewise, using more colors in +one design, and less colors in another design will reduce the +connectivity among your designs, since color information is relevant +to visual identity. +

+

When you propagate your artistic motif visual style to different +visual manifestations of CentOS Project corporate visual identity, it +is up to you to find out justice and compromise among all possible +variables you may face. +

2.39 The `trunk/Identity/Themes/Motifs/Modern/Backgrounds' Directory

+ + + +

2.39.1 Goals

+ + + + + +

2.39.2 Description

+ +

Inside `Motifs' directory, the `Backgrounds/' directory is +used to create vectorial designs using Inkscape and background images +using Gimp. Later, you can export background images as `.png' and +load them in your vectorial design project using the import feautre of +Inkscape. +

+

You may need to repeat this technic for different screen resoluions. +In that case you need to create one file for each screen resolution +and do the appropriate linking inside .svg to .png files. For example +if you need to produce background images in 800x600 you need to create +the following file: +

+
 
xcf/800x600.xcf
+
+

to produce the background image: +

+
 
img/800x600-bg.png
+
+

which is loaded in: +

+
 
svg/800x600.svg
+
+

to produce the final background image: +

+
 
img/800x600.png         
+
+

The `img/800x600.png' background image is produced automatically +by means of rendering scripts. +

+

In other cases (e.g. Anaconda), it is possible that you need to make +some variations to one background image that don't want to appear on +regular background images of the same resolution. In this case you +need to create a new and specific background image for that art +component. For example, if you need to produce the background image +used by Anconda (800x600) art works you create the file: +

+
 
xcf/800x600-anaconda.xcf
+
+

to produce the background image: +

+
 
img/800x600-anaconda-bg.png
+
+

which is loaded in: +

+
 
svg/800x600-anaconda.svg
+
+

to produce the file: +

+
 
img/800x600-anaconda.png
+
+

The 800x600-anaconda.png file is used by all Anaconda art works +sharing a common 800x600 screen resolution (e.g., Header, Progress, +Splash, Firstboot, etc.). The Anaconda Prompt is indexed to 16 colors +and 640x480 pixels so you need to create a 640x480 background image +for it, and take the color limitation into account when designing it. +

+

Background images without artistic motif are generally used as based +to build the Background images that do contain the theme artistic +motif. +

+

Background images are linked (using the import feature of +Inkscape) inside almost all theme art works. This structure let you +make centralized changes on the visual identity and propagate them +quickly to other areas. +

+

In this structure you design background images for different screen +resolutions based on the theme artistic motif. +

+

You may create different artistic motifs propositions based +on the same conceptual idea. The conceptual idea is what defines a +theme. Artistic motifs are interpretations of that idea. +

+

Inside this directory artistic motifs are organized by name (e.g., +TreeFlower, Modern, etc.). +

+

Each artistic motif directory represents just one unique artistic +motif. +

+

The artistic motif is graphic design used as common pattern to connect +all visual manifestations inside one unique theme. The artistic motif +is based on a conceptual idea. Artistic motifs provide visual style +to themes. +

+

Designing artistic motifs is for anyone interested in creating +beautiful themes for CentOS. When building a theme for CentOS, the +first design you need to define is the artistic motif. +

+ +

Inside CentOS Artwork Repository, theme visual styles (Motifs) and +theme visual structures (Models) are two different working lines. +When you design an artistic motif for CentOS you concentrate on its +visual style, and eventualy, use the centos-art command line +interface to render the visual style, you are currently producing, +against an already-made theme model in order to produce the final +result. Final images are stored under `Motifs/' directory using +the model name, and the model directory structure as reference. +

+

The artistic motif base structure is used by centos-art to +produce images automatically. This section describes each directory of +CentOS artistic motif base structure. +

+ + +

2.39.3 Usage

+ +

The `Backgrounds/' directory is probably the core component, +inside `Motifs/' directory structure. Inside `Backgrounds/' +directory you produce background images used by almost all theme +models (e.g., Distribution, Websites, Promotion, etc.). The +`Backgrounds/' directory can contain subdirectories to help you +organize the design process. +

1.4 Document Convenctions

+ +

In this manual the personal pronoun we is used to repesent +The CentOS Artwork SIG. This is, the group of persons building +the CentOS Artwork Repository. +

+

In this manual, certain words are represented in different fonts, +typefaces, sizes, and weights. This highlighting is systematic; +different words are represented in the same style to indicate their +inclusion in a specific category. The types of words that are +represented this way include the following: +

+
+
command
+
+

Linux commands (and other operating system commands, when used) are +represented this way. This style should indicate to you that you can +type the word or phrase on the command line and press Enter to invoke +a command. Sometimes a command contains words that would be displayed +in a different style on their own (such as file names). In these +cases, they are considered to be part of the command, so the entire +phrase is displayed as a command. For example: +

+

Use the centos-art identity --render='path/to/dir' command +to produce contents inside the `trunk/Identity' directory +structure. +

+
+ +
+
`file name'
+
+

File names, directory names, paths, and RPM package names are +represented this way. This style indicates that a particular file or +directory exists with that name on your system. Examples: +

+

The `init.sh' file in `trunk/Scripts/Bash/Cli/' directory is +the initialization script, written in Bash, used to automate most of +tasks in the repository. +

+

The centos-art command uses the `ImageMagick' RPM +package to convert images from PNG format to other formats. +

+
+ +
+
key
+
+

A key on the keyboard is shown in this style. For example: +

+

To use TAB completion to list particular files in a directory, +type ls, then a character, and finally the Tab key. Your +terminal displays the list of files in the working directory that +begin with that character. +

+
+ +
+
key-combination
+

A combination of keystrokes is represented in this way. For example: +

+

The Ctrl-Alt-Backspace key combination exits your graphical +session and returns you to the graphical login screen or the console. +

+
+ +
+
computer output
+
+

Text in this style indicates text displayed to a shell prompt such as +error messages and responses to commands. For example: +

+

The ls command displays the contents of a directory. For example: +

+
Config                           manual_renameEntry.sh
+manual_copyEntry.sh              manual_restoreCrossReferences.sh
+manual_deleteCrossReferences.sh  manual_searchIndex.sh
+
+

The output returned in response to the command (in this case, the +contents of the directory) is shown in this style. +

+
+ +

Additionally, we use several different strategies to draw your +attention to certain pieces of information. In order of urgency, these +items are marked as a note, tip, important, caution, or warning. For +example: +

+
info

Note

Remember that Linux is case sensitive. In other words, a +rose is not a ROSE is not a rOsE. +

+ +
Info

Tip

The directory `/usr/share/doc/' contains additional +documentation for packages installed on your system. +

+ +
Important

Important

If you modify the DHCP configuration file, the +changes do not take effect until you restart the DHCP daemon. +

+ +
Caution

Caution

Do not perform routine tasks as root -- use a +regular user account unless you need to use the root account for +system administration tasks. +

+ +
Warning

Warning

Be careful to remove only the necessary partitions. +Removing other partitions could result in data loss or a corrupted +system environment. +

2.46 The `trunk/Identity/Themes/Motifs/TreeFlower/Backgrounds' Directory

+ + + +

2.46.1 Goals

+ +

This section exists to orgnize backgrounds of TreeFlower +artistic motif. +

+ + +

2.46.2 Description

+ + + +

2.46.2.1 Desktop background

+ +

Once you have defined the vectorial artistic motif design, use the +centos-art.sh script (as described in usage section below) +to produce the png version of it. With the png version of your +vectorial design do the following: +

+

Open the png version with GIMP. +

+

Save the png version as a project of GIMP inside +`trunk/Identity/Themes/Motifs/TreeFlower/Backgrounds/Xcf' +directory, using the same name of your vectorial design but with the +`.xcf' extension. +

+

Now use GIMP to improve your design. Here you may add one layer for +pattern, another for colors, and so on until you find yourself +confortable with your artwork. For example, the following layer +distribution (from bottom to top) was used to build revision 285 of +file `1360x768.xcf' using TreeFlower artistic motif at +revision 241. +

+
+
Layer 1: Background
+
+

The first thing we did with GIMP was to create a layer named +`Background' to store the artistic motif (File > Open as layer). +This layer is the lowest layer in the image. Later, we started to +create layers one upon another to change the artistic motif visual +style. +

+
+
Layer 2: Shadow#1
+
+

This layer is above `Background' and contains a linear gradient +from left (000000) to right (transparent) covering the whole image. +This layer masks the artistic motif to avoid the effect of linear +gradient. This layer is 100% of opacity. +

+
+
Layer 3: Shadow#2
+
+

This layer is above `Shadow#1' and contains a linear gradient +from left (000000) to right (transparent) covering just the 70% of the +whole image aproximatly. This layer doesn't mask the artistic motif +which make the left part of it fall into the dark of linear gradient. +This layer is 100% of opacity. +

+
+
Layer 4: Pattern (Paper)
+
+

This layer is above `Shadow#2' an contains the paper pattern +shipped with GIMP 2.2. This layer doesn't mask the artistic motif so +the pattern is applied over the whole image. This layer is set to 15% +of opacity. +

+
+
Layer 5: Pattern (Stripes)
+
+

This layer is above `Pattern (Paper)' and contains the stripes +used over the artistic motif. This layer do masks the artistic motif +so the stripes are only applied to it. This layer is set to 10% of +opacity. +

+
+
Layer 6: Shadow#3
+
+

This layer is above `Pattern (Stripes)' and contains a linear +gradient from right (6600ff) to left (transparent). This layer masks +the artistic motif so the linear gradient doesn't affect it. This +layer is set to 15% of opacity. +

+
+
Layer 7: Shadow#4
+
+

This layer is above `Shadow#3' and contains a +linear gradient from left (000000) to right (transparent). This layer +do masks the artistic motif so the linear gradient doesn't affect it. +This layer is set to 10% of opacity. +

+
+
Layer 8: Color#1
+
+

This layer is above `Shadow#4' and is filled with orange (ffae00) +color over the whole image. This layer is set to 10% of opacity. +

+
+
Layer 9: Color#2
+
+

This layer is above `Color#1' and is filled with +blue (010a88) color over the whole image. This layer is set to 10% of +opacity. +

+
+
+ +
info

Note

There is no definite combination. To get the appropriate +visual design is a matter of constant testing and personal taste. +

+ +

Finally, use `Save as copy ...' option to export the final +design. To export the final design use the same name of your vectorial +design plus `-final.png' extension. +

+

You can repeat these steps to create images for other screen +resolutions. +

+ + +

2.46.2.2 Anaconda Prompt (syslinux) background

+ +

When building syslinux backgrounds it is needed to take into account +that the final image is reduced to 16 colors. In desktop background +there is no color limitation but syslinux does have. The goal of this +section is achieving a final syslinux background as close as possible +to desktop backgrounds using 16 colors only. +

+

Another point to consider is the forground and background definition +used by syslinux. The syslinux documentation says that the color set +in position 0 is the background and color set in position 7 is the +forground. The final palette of color used by our background will +match that specification. For great contrast we'll use black as +background and white as forground. At this poing we have black +(000000) and white (ffffff) colors in our syslinux palette, which left +us with 14 colors to play with. +

+

Let's begin with `Xcf/640x300.xcf' layer distribution from bottom +to top: +

+
+
Layer 1: Background
+
+

This layer is the lowest layer in the image composition and contains +the artistic motif image rendered for the same resolution (i.e., +`Img/Png/640x300.png'). This layer is set to 100% of opacity. +

+
+
Layer 2: Pattern (Paper)
+
+

This layer is placed above `Background' layer and contains the +paper pattern shipped with GIMP 2.2. This layer doesn't mask the +artistic motif. This layer is set to 30% of opacity. +

+
+
Layer 3: Pattern (Stripes)
+
+

This layer is placed above `Pattern (Paper)' layer and contains +the stripes pattern shipped with GIMP 2.2. This layer does mask the +artistic motif in order to apply the stripes over it only. The +background is not affected by the stripes pattern just the artistic +motif. This layer is set to 20% of opacity. +

+
+
Layer 4: Shadow#1
+
+

This layer is placed above `Pattern (Stripes)' layer and fills +the entire layer area with violet (6600ff) color. This layer do mask +the artistic motif in order to applied the violet color to the +background area outside the artistic motif only. This layer is set to +15% of opacity. +

+
+
Layer 5: Color#1
+
+

This layer is above `Shadow#1' and is filled with orange (ffae00) +color to cover the whole image. This layer is set to 10% of opacity. +

+
+
Layer 6: Color#2
+
+

This layer is above `Color#1' and is filled with blue (010a88) +color to cover the whole image. This layer is set to 10% of opacity. +

+
+
Layer 7: Shadow#2
+
+

This layer is above `Color#1' and contains a linear gradient from +left (000000) to right (transparent) covering 70% of the image +approximately. +

+
+
+ +

At this point we have the composition and should look like the desktop +backgrounds. Compared with desktop backgrounds there are some +differences in opacity. This is because in our testings the final +color information found with this composition produces an acceptable +16 color image. Of course this is something we haven't seen yet. +

+

To define the color information of our current coposition, save the +syslinux background composition we've done using `File > Save as +Copy ...' option in the following location: +

+
trunk/Identity/Themes/Motifs/TreeFlower/Backgrounds/Img/Png/640x300-final.png
+
+

Now, create the final png version of syslinux backgrounds using the +following command: +

+
centos-art render --entry=trunk/Identity/Themes/Motifs/TreeFlower/Distro/Anaconda/Prompt
+
+

This command will create syslinux-splash final images for all major +releases of CentOS distribution the repository has been configured to. +The important files here are `syslinux-splash.png', other +files may contain the wrong information because we haven't defined yet +the correct color information to use. +

+

Open one `syslinux-splash.png' file with GIMP and use the +`Image > Mode > Indexed' to reduce image colors up to 16 colors, +using the `Generate optimum palette' feature of GIMP. If the +image looks aceptable after reducing colors, use the `Palettes' +menu (Ctrl+P) of GIMP to import a new palette from file and name it +`CentOS-TreeFlower-Syslinux'. Once you've saved the palette, the +color information is stored at: +

+
~/.gimp-2.2/palettes/CentOS-TreeFlower-Syslinux.gpl
+
+

You need to edit `CentOS-TreeFlower-Syslinux.gpl' file in order +to set the appropriate order of colors. Remember black (000000) in +position 0, and white (ffffff) in position 7. Other positions are +irrelevant. When editing this file you may find that color reduction +did not set black and white colors to their respective values exactly. +Change that manually. For example, consider the following palette: +

+
GIMP Palette
+Name: CentOS-TreeFlower-Syslinux
+Columns: 16
+#
+  0   0   0	Background (black)
+ 23  20  35	Untitled
+ 34  25  48	Untitled
+ 37  35  60	Untitled
+ 47  36  68	Untitled
+ 37  54  86	Untitled
+ 60  48  90	Untitled
+255 255 255	Foreground (white)
+ 66  54  99	Untitled
+ 74  61  98	Untitled
+ 49  78 126	Untitled
+ 43  87 151	Untitled
+ 92  89  95	Untitled
+ 54 104 183	Untitled
+158 153 156	Untitled
+201 196 195	Untitled
+
+

Update the `Palettes' menu to get the new color positions from +the file you just edited and open the palette with double click. +

+

Update the `syslinux.gpl' file copying the following file: +

+
~/.gimp-2.2/palettes/CentOS-TreeFlower-Syslinux.gpl
+
+

to +

+
trunk/Identity/Themes/Motifs/TreeFlower/Colors/syslinux.gpl
+
+

With the `CentOS-TreeFlower-Syslinux' palette opened in the +`Palette Editor', open (Ctrl+O) the following file: +

+
trunk/Identity/Themes/Motifs/TreeFlower/Colors/syslinux.ppm
+
+

and replace its color information with that one in +`CentOS-TreeFlower-Syslinux' palette. When you are replacing +color information inside `syslilnux.ppm', remember to keep the +order of colors just as they are in the +`CentOS-TreeFlower-Palette' palette. +

+

The `syslinux.ppm' file is 16 pixels width and 1 pixel height, so +you probably need to zoom it a bit to set the color information in +their place when using the pen tool with the brush `Circle (01) +(1 x 1)'. +

+

Once you've updated the `syslinux.ppm' file, it is time to update +the following file: +

+
trunk/Identity/Themes/Motifs/TreeFlower/Colors/syslinux.hex
+
+

The `syslinux.hex' file contains the color information in +hexadecimal notation. The color information in hexadecimal notation +is required by ppmtolss16 command. The ppmtolss16 +command produces the final LSS16 image format that is used by syslinux +program inside CentOS distribution. +

+

The color information inside `syslinux.hex' must match the one in +`syslinux.ppm' and `syslinux.gpl'. For example, based on +`CentOS-TreeFlower-Syslinux' palette of colors above, consider +the following `syslinux.hex' file: +

+
#000000=0
+#171423=1
+#221930=2
+#25233c=3
+#2f2444=4
+#253656=5
+#3c305a=6
+#ffffff=7
+#423663=8
+#4a3d62=9
+#314e7e=10
+#2b5797=11
+#5c595f=12
+#3668b7=13
+#9e999c=14
+#c9c4c3=15

2.48 The `trunk/Locales' Directory

+ +

The `trunk/Locales' directory exists to store the translation +messages used to produce content in different languages. +

+

Translation messages are organized using the directory structure of +the component being translated. For example, if we want to provide +translation messages for `trunk/Manuals/Filesystem', then the +`trunk/Locales/Manuals/Filesystem' directory needs to be created. +

+

Once the locale directory exists for the component we want to provide +translation messages for, it is necessary to create the translation +files where translation messages are. The translation files follows +the concepts of xml2po and GNU gettext tools. +

+

The basic translation process is as follow: first, translatable +strings are extracted from files and a portable object template (.pot) +is created or updated with the information. Using the portable object +template, a portable object (.po) is created or updated for translator +to locale the messages retrived. Finally, a machine object (.mo) is +created from portable object to sotore the translated messages. +

+

Inside the repository there are two ways to retrive translatable +strings from files. The first one is through xml2po command +and the second through xgettext command. The xml2po +is used to retrive translatable strings from XML files (e.g., Scalable +Vector Graphics, DocBook, etc.) and the xgettext command is +used to retrive translatable strings from shell scripts files (e.g., +the files that make the centos-art.sh command-line +interface). +

+

When translatable strings are retrived from XML files, using the +xml2po command, there is no need to create the machine +object as we do when translatable strings ar retrived from shell +files, using the xgettext command. The xml2po +produces a temporal machine object in order to create a translated XML +file. Once the translated XML file has been created the machine object +is no longer needed. On the other hand, the machine object produced by +the xgettext command is required by the system in order for +the show shell script localized messages. +

+

Another difference between xml2po and xgettext we +need to be aware of is the directory structure used to store machine +objects. In xml2po, the machine object is created in the +current working directory as `.xml2po.mo' and can be safetly +removed once the translated XML file has been created. In the case of +xgettext, the machine object needs to be stored in the +`$TEXTDOMAIN/$LOCALE/LL_MESSAGES/$TEXTDOMAIN.mo' file in order +for the system to interpret it and should not be removed since it is +the file that contain the translation messages themselves. +

+

Automation of localization tasks is achived through the locale +functionality of command-line interface. +

2.50 The `trunk/Locales/Identity/Brands' Directory

+ + + +

2.50.1 Goals

+ + + + + +

2.50.2 Description

+ +

Translation files, inside `trunk/Translations/Identity/Brands' +translation entry, don't use default rendering translation +functionality, they use the following translation pre-rendering +configuration file instead: +

+
/home/centos/artwork/trunk/Translation/Identity/Brands/render.conf.sh
+
+

Inside `trunk/Translations/Identity/Brands' translation entry, +translation files are symbolic links pointing to the common template +translation structure, inside the translation template (`Tpl/') +directory. +

+

Inside `trunk/Translations/Identity/Brands' translation entry, +translation files are created using identity design templates as +reference. The translation pre-rendering script creates a translation +structure where the translation template (`Tpl/') directory +structure applies to each single design template available. +

+

For example, if the brands' translation template (`Tpl/') +directory has 30 translation files, and there are 20 design templates; +the brands' translation pre-rendering script creates a translation +structure of symbolic links where the 30 translation files apply the +20 design templates one by one, producing 600 translation symbolic +links as result. At this point, when rendering identity, the +centos-art script considers translation symbolic links as +translation files. +

+

Translation file names, inside brands' translation template +(`Tpl') directory have special meaning: +

+ + +

2.50.2.1 Conventional file names

+ +

Convenctional file names look like `blue.sed', `2c-a.sed', +etc. Replacement commands inside translation file are applied to +design templates and translation file names are used as final image +name. The image dimensions use the same dimensions that design +template has. +

+ + +

2.50.2.2 Numeric file names

+ +

Numeric file names look like `300.sed', `200.sed', etc. +Replacements commands inside translation files are applied to design +templates, and translation file names are used as final image name. +The final image is saved using an specific `width' defined by the +number part of the translation file name. The image `height' is +automatically scaled based on the previous `width' definition to +maintain the designing ratio. +

+

For example, if your design template has 400x200 pixels of dimension, +and you apply a translation file named `300.sed' to it, the final +image you get as result will have 300x100 pixels of dimension. The +same is true if you use higher numbers like `1024.sed', `2048.sed', +etc. In these cases you have bigger images proportionally. +

+

As we are using scalable vector graphics to design identity templates, +the image size you produce is not limitted in size. You can use one +design template produced in 400x200 pixels to produce larger or +shorter PNG images using numeric translation files as described +above. +

+ + +

2.50.2.3 Translation markers

+ +

Inside `trunk/Translations/Identity/Brands/', translation files +combine the following translation markers: +

+
+
`#000000'
+
+

Specify which color to use when rendering brand images. +

+
info

Note

As translation files inside +`trunk/Translations/Identity/Brands' are symbolic links that +point to template translation files, translation markers are defined +inside template translation files. +

+
+
+ + + +

2.50.3 Usage

+ +

To render brands' translation files, use the following command: +

+
centos-art render --translation=/home/centos/artwork/trunk/Translations/Identity/Brands

2.52 The `trunk/Locales/Identity/Fonts' Directory

+ + + +

2.52.1 Goals

+ +

This section exists to organize fonts translation files. +

+ +

2.52.2 Description

+ +

Translation files, inside `trunk/Translations/Fonts', have the +following structure: +

+
s!font-family:Denmark!font-family:DejaVu LGC Sans!
+s!font-weight:normal!font-weight:bold!
+s!font-style:normal!font-style:italic!
+
+

Inside `trunk/Translations/Fonts', there is one translation file +for each font preview image you want to produce. This way, we create +one translation file for each font-family we use somewhere inside +CentOS visual identity. +

+
Important

Important

Do not create translation files for +font-families not used somewhere inside CentOS visual identity. The +identity of font entry (see section The `trunk/Identity/Fonts' Directory) is used as +reference when someone needs to know which font-families are allowed +to use inside CentOS visual identity. +

+ + + +

2.52.2.1 Translation Markers

+ +

Inside `trunk/Translations/Identity/Fonts', translation files +combine the following translation markers: +

+
+
`font-family:Denmark'
+

Specify which font family to use when rendering font preview images. +

+
`font-weight:normal'
+

Specify which font weight to use when rendering font preview images. +

+
`font-style:normal'
+

Specify which font style to use when rendering font preview images. +

+
+ + + +

2.52.3 Usage

+ +

Inside `trunk/Translations/Fonts' you use your favorite text +editor to create translation files. Inside +`trunk/Translations/Fonts' there is not translation template +directory (`Tpl/'), nor translation rendering using +centos-art script. For example, to create the +`dejavu_lgc_sans-boldoblique.sed' translation file using +vim editor, type the following command: +

+
vim /home/centos/artwork/trunk/Translations/Fonts/dejavu_lgc_sans-boldoblique.sed

2.57 The `trunk/Locales/Identity/Themes/Distro/Anaconda/Progress' Directory

+ + + +

2.57.1 Goals

+ + + + + +

2.57.2 Description

+ +

Use the following command to produce translation files based: +

+
 
trunk/Translations/Identity/Themes/Distro/Anaconda/Progress
+`-- Tpl
+    |-- en
+    |   |-- 01-welcome.sed
+    |   |-- 02-donate.sed
+    |   `-- 03-yum.sed
+    `-- es
+        |-- 01-welcome.sed
+        |-- 02-donate.sed
+        `-- 03-yum.sed
+
+

In order to produce the slide images in PNG format we need to have the +translation files first. So we use the following commands to create +translation files for CentOS 3, 4, and 5 major releases: +

+
 
centos-art render --translation --filter='3,4,5'
+
+

The above commands will produce the following translation structure: +

+
 
trunk/Translations/Identity/Themes/Distro/Anaconda/Progress
+|-- 3
+|   |-- en
+|   |   |-- 01-welcome.sed
+|   |   |-- 02-donate.sed
+|   |   `-- 03-yum.sed
+|   `-- es
+|       |-- 01-welcome.sed
+|       |-- 02-donate.sed
+|       `-- 03-yum.sed
+|-- 4
+|   |-- en
+|   |   |-- 01-welcome.sed
+|   |   |-- 02-donate.sed
+|   |   `-- 03-yum.sed
+|   `-- es
+|       |-- 01-welcome.sed
+|       |-- 02-donate.sed
+|       `-- 03-yum.sed
+|-- 5
+|   |-- en
+|   |   |-- 01-welcome.sed
+|   |   |-- 02-donate.sed
+|   |   `-- 03-yum.sed
+|   `-- es
+|       |-- 01-welcome.sed
+|       |-- 02-donate.sed
+|       `-- 03-yum.sed
+`-- Tpl
+    |-- en
+    |   |-- 01-welcome.sed
+    |   |-- 02-donate.sed
+    |   `-- 03-yum.sed
+    `-- es
+        |-- 01-welcome.sed
+        |-- 02-donate.sed
+        `-- 03-yum.sed
+
+

At this point we have all the translation files we need to produce +Anaconda progress welcome, donate and yum slides images; in English +and Spanish languages; for CentOS 3, CentOS 4, and CentOS 5. That is, +a sum of 18 images around. +

+

Now, with translation files in place, let's move to +`trunk/Identity' structure and render them. +

+ + + + +

2.57.3 Usage

+ +

Translation rendering is described in `trunk/Translations' +documentation entry (-- Removed(pxref:trunk Translations) --). +

2.62 The `trunk/Scripts/Bash' Directory

+ + + +

2.62.1 Goals

+ +

The `trunk/Scripts/Bash' directory exists to organize the trunk +development line of `centos-art.sh' automation script. The +`centos-art.sh' script standardizes frequent tasks inside your +working copy of CentOS Artwork Repository. +

+ + +

2.62.2 Description

+ +

The best way to understand `centos-art.sh' automation script is +studying its source code. However, as start point, you may prefer to +read an introductory resume before diving into the source code +details. +

+

The `centos-art.sh' script is written in Bash. Most tasks, inside +`centos-art.sh' script, have been organized in many specific +functionalities that you can invoke from the centos-art +command-line interface. +

+

When you type the centos-art command in your terminal, the +operating system trys to execute that command. In order to execute the +command, the operating system needs to know where it is, so the +operating system uses the PATH environment variable to look for +that command location. If your system was prepared to use CentOS +Artwork Repository correctly (-- Removed(pxref:trunk Scripts Bash Functions +Verify) --), you should have a symbolic link inside `~/bin/' +directory that points to the `centos-art.sh' script file. As +`~/bin/' directory is, by default, inside PATH environment +variable, the execution of centos-art command runs the +`centos-art.sh' script. +

+

When `centos-art.sh' script is executed, the first it does is +executing the `trunk/Scripts/Bash/initEnvironment.sh' script to +initialize global variables (e.g., gettext variables) and +global function scripts. Global function scripts are located inside +`trunk/Scripts/Bash/Functions' directory and their file names +begin with `cli'. Global function scripts provide common +functionalities that can be used anywhere inside `centos-art.sh' +script execution environment. +

+

Once global variables and function scripts have been loaded, +`centos-art.sh' script executes the cli global function +from `cli.sh' function script to retrive command-line arguments +and define some default values that may be used later by specific +function scripts (-- Removed(pxref:trunk Scripts Bash Functions) --). +

+

As convenction, the `centos-art.sh' command-line arguments have +the following format: +

+
centos-art arg1 --arg2=val2 --arg3=val3
+
+

In the above example, `centos-art' is the command you use to +invoke `centos-art.sh' script. The `arg1' is required and +represents the functionality you want to perform (e.g., +`verify', `render', `locale', `manual', +etc.). The remaining arguments are modifiers to `arg1'. The +`--arg2' definition is required and represets, specifically, +the action inside the functionality you want to perform. The +`--arg3' and on, are optional. +

+

Once command-line arguments have been retrived, the +`centos-art.sh' script loads specific functionalities using the +`cli_getFunctions.sh' function script. Only one specific +functionality can be loaded at one script execution I.e., you run +centos-art.sh script to run just one functionality. +

+
+

+

Functionalities are implemented by means of actions. Once the +functionality has been initiazalized, actions initialization take +place for that functionality. Actions initialization model is very +similar to functions initialization model. But with the difference, +that actions are loaded inside function environment, and so, share +variables and functions defined inside function environment. +

2. Repository File System

+ +

The CentOS Artwork Repsotiroy File System is the place where we +organize The CentOS Project Corporate Visual Identity. The CentOS +Artwork Repository uses directories to organize files and describe +conceptual idea about corporate identity. Such conceptual ideas are +explained in each directory related documentation entry. +

+

In this chapter you'll learn what each directory inside The CentOS +Artwork Repository is for and so, how you can make use of them. For +that purpose, the following list of directories is available for you +to explore: +

2.64 The `trunk/Scripts/Bash/Cli/Functions' Directory

+ + + +

2.64.1 Goals

+ +

The `trunk/Scripts/Bash/Functions' directory exists to organize +`centos-art.sh' specific functionalities. +

+ + +

2.64.2 Description

+ +

The specific functions of `centos-art.sh' script are designed +with "Software Toolbox" philosophy (see (coreutils.info)Toolbox introduction) in mind: each program "should do one +thing well". Inside `centos-art.sh' script, each specific +functionality is considered a program that should do one thing well. +Of course, if you find that they still don't do it, feel free to +improve them in order for them to do so. +

+

The specific functions of `centos-art.sh' script are organized +inside specific directories under `trunk/Scripts/Bash/Functions' +location. Each specific function directory should be named as the +function it represents, with the first letter in uppercase. For +example, if the function name is render, the specific function +directory for it would be `trunk/Scripts/Bash/Functions/Render'. +

+

To better understand how specific functions of `centos-art.sh' +script are designed, lets create one function which only goal is to +output different kind of greetings to your screen. +

+

When we create specific functions for `centos-art.sh' script it +is crucial to know what these functions will do exactly and if there +is any function that already does what we intend to do. If there is no +one, it is good time to create them then. Otherwise, if +functionalities already available don't do what you exactly expect, +contact their authors and work together to improve them. +

+
Info

Tip

Join CentOS developers mailing list +centos-art@centos.org to share your ideas. +

+ +

It is also worth to know what global functions and variables do we +have available inside `centos-art.sh' script, so advantage can be +taken from them. Global variables are defined inside global function +scripts. Global functions scripts are stored immediatly under +`trunk/Scripts/Bash/Functions' directory, in files begining with +`cli' prefix. +

+

OK, let's begin with our functionality example. +

+

What function name do we use? Well, lets use greet. Note that +`hello' word is not a verb; but an expression, a kind of +greeting, an interjection specifically. In contrast, `greet' is a +verb and describes what we do when we say `Hello!', `Hi!', +and similar expressions. +

+

So far, we've gathered the following function information: +

+
Name: greet
+Path: trunk/Scripts/Bash/Functions/Greet
+File: trunk/Scripts/Bash/Functions/Greet/greet.sh
+
+

The `greet.sh' function script is the first file +`centos-art.sh' script loads when the `greet' functionality +is called using commands like `centos-art greet --hello='World''. +The `greet.sh' function script contains the greet function +definition. +

+

Inside `centos-art.sh' script, as convenction, each function +script has one top commentary, followed by one blank line, and then +one function defintion below it only. +

+

Inside `centos-art.sh' script functions, top commentaries have +the following components: the functionality description, one-line for +copyright note with your personal information, the license under +which the function source code is released --the `centos-art.sh' +script is released as GPL, so do all its functions--, the $Id$ +keyword of Subversion is later expanded by svn propset +command. +

+

In our greet function example, top commentary for +`greet.sh' function script would look like the following: +

+
#!/bin/bash
+#
+# greet.sh -- This function outputs different kind of greetings to
+# your screen. Use this function to understand how centos-art.sh
+# script specific functionalities work.
+#

+# USA.
+# 
+# ----------------------------------------------------------------------
+# $Id$
+# ----------------------------------------------------------------------
+
+

After top commentary, separated by one blank line, the greet +function definition would look like the following: +

+
function greet {
+
+    # Define global variables.
+
+    # Define command-line interface.
+    greet_getActions
+
+}
+
+

The first definition inside greet function, are global +variables that will be available along greet function execution +environment. This time we didn't use global variable definitions for +greet function execution environment, so we left that section +empty. +

+

Later, we call greet_getActions function to define the +command-line interface of greet functionality. The command-line +interface of greet functionality defines what and how actions +are performed, based on arguments combination passed to +`centos-art.sh' script. +

+
function greet_getActions {
+
+    case "$ACTIONNAM" in
+
+        --hello )
+            greet_doHello
+            ;;
+
+        --bye )
+            greet_doBye
+            ;;
+
+        * )
+            cli_printMessage "`gettext "The option provided is not valid."`"
+            cli_printMessage "$(caller)" 'AsToKnowMoreLine'
+
+    esac
+
+}
+
+

The ACTIONNAM global variable is defined in `cli.sh' +function script and contains the value passed before the equal sign +(i.e., `=') in the second command-line argument of +`centos-art.sh' script. For example, if the second command-line +argument is `--hello='World'', the value of ACTIONNAM +variable would be `--hello'. Using this configuration let us +deside which action to perform based on the action name passed to +`centos-art.sh' script as second argument. +

+

The greet function definition makes available two valid +greetings through `--hello' and `--bye' options. If no +one of them is provided as second command-line argument, the `*' +case is evaluated instead. +

+

The `*' case and its two lines further on should always be +present in `_getActions.sh' function scripts, no matter what +specific functionality you are creating. This convenction helps the +user to find out documentation about current functionality in use, +when no valid action is provided. +

+

The greet_doHello and greet_doBye function definitions +are the core of greet specific functionality. In such function +definitions we set what our greet function really does: to +output different kinds of greetings. +

+
function greet_doHello {
+
+    cli_printMessage "`gettext "Hello"` $ACTIONVAL"
+
+}
+
+

The greet_doHello function definition is stored in +`greet_doHello.sh' function script. +

+
function greet_doBye {
+
+    cli_printMessage "`gettext "Goodbye"` $ACTIONVAL"
+
+}
+
+

The greet_doBye function definition is stored in the +`greet_doBye.sh' function script. +

+

Both `greet_doHello.sh' and `greet_doBye.sh' function +scripts are stored inside greet function directory path (i.e. +`trunk/Scripts/Bash/Functions/Greet'). +

+

The ACTIONVAL global variable is defined in `cli.sh' +function script and contains the value passed after the equal sign +(i.e., `=') in the second command-line argument of +`centos-art.sh' script. For example, if the second command-line +argument is `--hello='World'', the value of ACTIONVAL +variable would be `World' without quotes. +

+

Let's see how greet specific functionality files are organzied +under greet function directory. To see file organization we use +the tree command: +

+
trunk/Scripts/Bash/Functions/Greet
+|-- greet_doBye.sh
+|-- greet_doHello.sh
+|-- greet_getActions.sh
+`-- greet.sh
+
+

To try the greet specific functionality we've just created, +pass the function name (i.e., `greet') as first argument to +`centos-art.sh' script, and any of the valid options as second +argument. Some examples are illustrated below: +

+
[centos@projects ~]$ centos-art greet --hello='World'
+Hello World
+[centos@projects ~]$ centos-art greet --bye='World'
+Goodbye World
+[centos@projects ~]$ 
+
+

The word `World' in the examples above can be anything. In fact, +change it to have a little fun. +

+

Now that we have a specific function that works as we expect, it is +time to document it. To document greet specific functionality, +we use its directory path and the manual functionality +(-- Removed(pxref:trunk Scripts Bash Functions Manual) --) of `centos-art.sh' +script, just as the following command illustrates: +

+
centos-art manual --edit=trunk/Scripts/Bash/Functions/Greet
+
+

To have a well documented function helps user to understand how your +function really works, and how it should be used. When no valid +action is passed to a function, the `centos-art.sh' script uses +the function documentation entry as vehicle to communicate which the +valid functions are. When no documentation entry exists for a +function, the `centos-art.sh' script informs that no +documentation entry exists for such function and requests user to +create it right at that time. +

+

Now that we have documented our function, it is time to translate its +output messages to different languages. To translate specific +functionality output messages to different languages we use the +locale functionality (-- Removed(pxref:trunk Scripts Bash Functions +Locale) --) of `centos-art.sh' script, just as the following command +illustrates: +

+
centos-art locale --edit
+
+
Warning

Warning

To translate output messages in different languages, +your system locale information --as in LANG environment +variable-- must be set to that locale you want to produce translated +messages for. For example, if you want to produce translated messages +for Spanish language, your system locale information must be set to +`es_ES.UTF-8', or similar, first. +

+ +

Well, it seems that our example is rather complete by now. +

+

In greet function example we've described so far, we only use +cli_printMessage global function in action specific function +definitions in order to print messages, but more interesting things +can be achieved inside action specific function definitions. For +example, if you pass a directory path as action value in second +argument, you could retrive a list of files from therein, and process +them. If the list of files turns too long or you just want to control +which files to process, you could add the third argument in the form +`--filter='regex'' and reduce the amount of files to process +using a regular expression pattern. +

+

The greet function described in this section may serve you as +an introduction to understand how specific functionalities work inside +`centos-art.sh' script. With some of luck this introduction will +also serve you as motivation to create your own `centos-art.sh' +script specific functionalities. +

+

By the way, the greet functionality doesn't exist inside +`centos-art.sh' script yet. Would you like to create it? +

+ + +

2.64.3 Usage

+ + + +

2.64.3.1 Global variables

+ +

The following global variables of `centos-art.sh' script, are +available for you to use inside specific functions: +

+
+
Variable: TEXTDOMAIN + +
+

Default domain used to retrieve translated messages. This value is set +in `initFunctions.sh' and shouldn't be changed. +

+ +
+
Variable: TEXTDOMAINDIR + +
+

Default directory used to retrieve translated messages. This value is +set in `initFunctions.sh' and shouldn't be changed. +

+ +
+
Variable: FUNCNAM + +
+

Define function name. +

+

Function names associate sets of actions. There is one set of actions +for each unique function name inside `centos-art.sh' script. +

+

Dunction names are passed as first argument in `centos-art.sh' +command-line interface. For example, in the command `centos-art +render --entry=path/to/dir --filter=regex', the ACTION passed to +`centos-art.sh' script is `render'. +

+

When first argument is not provided, the `centos-art.sh' script +immediatly ends its execution. +

+ +
+
Variable: FUNCDIR + +
+
+ +
+
Variable: FUNCDIRNAME + +
+
+ +
+
Variable: FUNCSCRIPT + +
+
+ +
+
Variable: FUNCCONFIG + +
+
+ +
+
Variable: ACTIONNAM + +
+

Define action name. +

+

Each action name identifies an specific action to perform, inside an +specific function. +

+

Action name names aare passed as second argument in +`centos-art.sh' command-line interface. For example, in the +command `centos-art render --entry=path/to/dir --filter=regex', +the ACTIONNAM passed to `centos-art.sh' script is +`--entry'. +

+

When second argument is not provided, the `centos-art.sh' script +immediatly ends its execution. +

+ +
+
Variable: ACTIONVAL + +
+

Define action value. +

+

Action values are associated to just one action name. Action values +contain the working copy entry over which its associated action will be +performed in. Working copy entries can be files or directories inside +the working copy. +

+ +
+
Variable: REGEX + +
+

Define regular expression used as pattern to build the list of files +to process. +

+

By default, REGEX variable is set to .+ to match all +files. +

+

Functions that need to build a list of files to process use the option +`--filter' to redefine REGEX variable default value, and +so, control the amount of files to process. +

+ +
+
Variable: ARGUMENTS + +
+

Define optional arguments. +

+

Optional arguments, inside `centos-art.sh' script, are considered +as all command-line arguments passed to `centos-art.sh' script, +from third argument position on. For example, in the command +`centos-art render --entry=path/to/dir --filter=regex' , the +optional arguments are from `--filter=regex' argument on. +

+

Optional arguments are parsed using getopt command through +the following base construction: +

+
# Define short options we want to support.
+local ARGSS=""
+
+# Define long options we want to support.
+local ARGSL="filter:,to:"
+
+# Parse arguments using getopt(1) command parser.
+cli_doParseArguments
+
+# Reset positional parameters using output from (getopt) argument
+# parser.
+eval set -- "$ARGUMENTS"
+
+# Define action to take for each option passed.
+while true; do
+    case "$1" in
+        --filter )
+            REGEX="$2" 
+            shift 2
+            ;;
+        --to )
+            TARGET="$2" 
+            shift 2
+            ;;
+        * )
+            break
+    esac
+done
+
+

Optional arguments provide support to command options inside +`centos-art.sh' script. For instance, consider the Subversion +(svn) command, where there are many options (e.g., +`copy', `delete', `move', etc), and inside each +option there are several modifiers (e.g., `--revision', +`--message', `--username', etc.) that can be combined one +another in their short or long variants. +

+

The ARGUMENTS variable is used to store arguments passed from +command-line for later use inside `centos-art.sh' script. Storing +arguments is specially useful when we want to run a command with some +specific options from them. Consider the following command: +

+
centos-art path --copy=SOURCE --to=TARGET --message="The commit message goes here." --username='johndoe'
+
+

In the above command, the `--message', and `--username' +options are specific to svn copy command. In such cases, +options are not interpreted by `centos-art.sh' script itself. +Instead, the `centos-art.sh' script uses getopt to +retrive them and store them in the ARGUMENTS variable for later +use, as described in the following command: +

+
# Build subversion command to duplicate locations inside the
+# workstation.
+eval svn copy $SOURCE $TARGET --quiet $ARGUMENTS
+
+

When getopt parses ARGUMENTS, we may use short options +(e.g., `-m') or long options (e.g., `--message'). When +we use short options, arguments are separated by one space from the +option (e.g., `-m 'This is a commit message.''). When we use +long options arguments are separated by an equal sign (`=') +(e.g., `--message='This is a commit message''). +

+

In order for getopt to parse ARGUMENTS correctly, it +is required to provide the short and long definition of options that +will be passed or at least supported by the command performing the +final action the function script exists for. +

+

As convenction, inside `centos-art.sh' script, short option +definitions are set in the ARGSS variable; and long option +definitions are set in the ARGSL variable. +

+

When you define short and long options, it may be needed to define +which of these option arguments are required and which not. To define +an option argument as required, you need to set one colon `:' +after the option definition (e.g., `-o m: -l message:'). On +the other hand, to define an option argument as not required, you need +to set two colons `::' after the option definition (e.g., +`-o m:: -l message::'). +

+ +
+
Variable: EDITOR + +
+

Default text editor. +

+

The `centos-art.sh' script uses default text EDITOR to edit +pre-commit subversion messages, translation files, configuration +files, script files, and similar text-based files. +

+

If EDITOR environment variable is not set, `centos-art.sh' +script uses `/usr/bin/vim' as default text editor. Otherwise, the +following values are recognized by `centos-art.sh' script: +

+
    +
  • `/usr/bin/vim' +
  • `/usr/bin/emacs' +
  • `/usr/bin/nano' +
+ +

If no one of these values is set in EDITOR environment variable, +`centos-art.sh' uses `/usr/bin/vim' text editor by default. +

+ + + +

2.64.3.2 Global functions

+ +

Function scripts stored directly under +`trunk/Scripts/Bash/Functions/' directory are used to define +global functions. Global functions can be used inside action specific +functionalities and or even be reused inside themselves. This section +provides introductory information to global functions you can use +inside `centos-art.sh' script. +

+
+
Function: cli_checkActionArguments + +
+

Validate action value (ACTIONVAL) variable. +

+

The action value variable can take one of the following values: +

+
    +
  1. Path to one directory inside the local working copy, +
  2. Path to one file inside the local working copy, +
+ +

If another value different from that specified above is passed to +action value variable, the `centos-art.sh' script prints an error +message and ends script execution. +

+ +
+
Function: cli_checkFiles FILE [TYPE] + +
+

Verify file existence. +

+

cli_checkFiles receives a FILE absolute path and performs +file verification as specified in TYPE. When TYPE is not +specified, cli_checkFiles verifies FILE existence, no +matter what kind of file it be. If TYPE is specified, use one +of the following values: +

+
+
`d'
+
`directory'
+

Ends script execution if FILE is not a directory. +

+

When you verify directories with cli_checkFiles, if directory doesn't +exist, `centos-art.sh' script asks you for confirmation in order +to create that directory. If you answer positively, +`centos-art.sh' script creates that directory and continues +script flows normally. Otherwise, if you answer negatively, +`centos-art.sh' ends script execution with an error and +documentation message. +

+
+
`f'
+
`regular-file'
+

Ends script execution if FILE is not a regular file. +

+
`h'
+
`symbolic-link'
+

Ends script execution if FILE is not a symbolic link. +

+
`x'
+
`execution'
+

Ends script execution if FILE is not executable. +

+
`fh'
+

Ends script execution if FILE is neither a regular file nor a +symbolic link. +

+
`fd'
+

Ends script execution if FILE is neither a regular file nor a +directory. +

+
`isInWorkingCopy'
+

Ends script execution if FILE is not inside the working copy. +

+
+ +

As default behaviour, if FILE passes all verifications, +`centos-art.sh' script continues with its normal flow. +

+ +
+
Function: cli_commitRepoChanges [LOCATION] + +
+

Syncronize changes between repository and working copy. +

+

The cli_commitRepoChanges function brings changes from the +central repository down to the working copy--using svn +update--, checks the working copy changes--using svn +status command--, prints status report--using both svn +update and svn status commands output, and finally, commits +recent changes from the working copy up to the repository--using +svn commit command--. +

+

Previous to commit the working copy changes up to the central +repository, the cli_commitRepoChanges function asks you to +verify changes--using svn diff command--, and later, +another confirmation question is shown to be sure you really want to +commit changes up to central repository. +

+

If LOCATION argument is not specified, the value of +ACTIONVAL variable is used as reference instead. +

+
+
----------------------------------------------------------------------
+--> Bringing changes from the repository into the working copy
+--> Checking changes in the working copy

+
+

Figure 2.3: The cli_commitRepoChanges function output. + +

+

Call the cli_commitRepoChanges function before or/and after +calling functions that modify files or directories inside the working +copy as you may need to. +

+ +
+
Function: cli_doParseArguments + +
+

Redefine arguments (ARGUMENTS) global variable using +getopt command output. For more information about how to use +cli_doParseArguments function, see ARGUMENTS variable +description above. +

+ +
+
Function: cli_doParseArgumentsReDef $@ + +
+

Initialize/reset arguments (ARGUMENTS) global variable using +positional parameters variable ($@) as reference. +

+

When we work inside function definitions, positional parameters are +reset to the last function definition positional parameters. If you +need to redefine positional parameters from one specific function, you +need to call cli_doParseArgumentsReDef with the positional +parameters variable ($@), set as first argument, to that +specific function you want to redefine positional parameters at. +

+ +
+
Function: cli_getArguments + +
+

Initialize function name (FUNCNAM), action name +(ACTIONNAM), and action value (ACTIONVAL) global +variables, using positional parameters passed in $@ variable. +

+

The cli_getArguments function is called from cli.sh +function script, using cli function positional parameters +(i.e., the positional parameters passed as arguments in the +command-line) as first function argument. +

+

Once command-line positional parameters are accesible to +`centos-art.sh' script execution evironment, +cli_getArguments uses regular expression to retrive +action variables from first and second argument. The first argument +defines the value used as function name (FUNCNAM), and the +second argument defines both values used as action name +(ACTIONNAM) and action value (ACTIONVAL), respectively. +

+

The first argument is a word in lower case. This word specifies the +name of the functionality you want to use (e.g., `render' to +render images, `manual' to work on documentation, and so on.) +

+

The second argument has a long option style (e.g., +`--option=value'). The `--option' represents the action name +(ACTIONNAM), and the characters inbetween the equal sign +(`=') and the first space character, are considered as the action +value (ACTIONVAL). In order to provide action values with space +characters inbetween you need to enclose action value with quotes like +in `--option='This is long value with spaces inbetween''. +Generally, action values are used to specify paths over which the +action name acts on. +

+

Once action related variables (i.e., FUNCNAM, ACTIONNAM, +and ACTIONVAL) are defined and validated, +cli_getArguments shifts the positional arguments to remove the +first two arguments passed (i.e., those used to retrive action related +variables) and redefine the arguments (ARGUMENTS) global +variable with the new positional parameters information. +

+
Function: cli_getFunctions + +
+

Initialize funtionalities supported by `centos-art.sh' script. +

+

Functionalities supported by `centos-art.sh' script are organized +in functionality directories under +`trunk/Scripts/Bash/Functions/' directory. Each functionality +directory stores function scripts to the functionality such directory +was created for. Function scripts contain function definitions. +Function definitions contain several commands focused on achieving one +specific task only (i.e., the one such functionality was created for). +

+

In order for `centos-art.sh' script to recognize a functionality, +such functionality needs to be stored under +`trunk/Scripts/Bash/Functions/' in a directory written +capitalized (i.e., the whole name is written in lowercase except the +first character which is in uppercase). The directory where one +specific functionality is stored is known as the `functionality +directory'. +

+

Inside each functionality directory, the functionalty itself is +implemented through function scripts. Function scripts are organized +in files independently one another and written in `camelCase' +format with the function name as prefix. Separation between prefix +and description is done using underscore (`_') character. +

+

In order for `centos-art.sh' script to load functionalities +correctly, function definition inside function scripts should be set +using the `function' reserved word, just as in the following +example: +

+
function prefix_doSomething {
+
+    # Do something here...
+
+}
+
+

The above function definition is just a convenction we use, in order +to make identification of function names easier read and automate by +`centos-art.sh' script initialization commands, once +`centos-art.sh' script determines which functionality directory +to use. Specifically, in order to initialize and export functions, +`centos-art.sh' script executes all function scripts inside the +functionality directory, and later grep on them using a +regular expression pattern, where the `function' reserved word is +used as reference to retrive the function names and export them to +`centos-art.sh' script execution environment, and so, make +function definitions --from function scripts inside the functionality +directory-- available for further calls. +

+

If the functionality specified in the command-line first argument +doesn't have a functionality directory, `centos-art.sh' script +considers the functionality provided in the command-line as invalid +functionality and immediatly stops script execution with an error +message. +

+

In order to keep visual consistency among function scripts, please +consider using the following function script design model as template +for your own function scripts: +

+
#!/bin/bash
+#
+# prefix_doSomething.sh -- This function illustrates function scripts
+# design model you can use to create your own function scripts inside
+# centos-art.sh script.

+function prefix_doSomething {

+
+}
+
+ +
+
Function: cli_getCountryCodes [FILTER] + +
+

Output country codes supported by `centos-art.sh' script. +

+

The cli_getCountryCodes function outputs a list with country +codes as defined in ISO3166 standard. When FILTER is provided, +cli_getCountryCodes outputs country codes that match +FILTER regular expression pattern. +

+ +
+
Function: cli_getCountryName [FILTER] + +
+

Outputs country name supported by `centos-art.sh' script. +

+

The cli_getCountryName function reads one language locale code +in the format LL_CC and outputs the name of its related country as in +ISO3166. If filter is specified, cli_getCountryName returns the +country name that matches the locale code specified in FILTER, +exactly. +

+ +
+
Function: cli_getCurrentLocale + +
+

Output current locale used by `centos-art.sh' script. +

+

The cli_getCurrentLocale function uses LANG environment +variable to build a locale pattern that is later applied to +cli_getLocales function output in order to return the current +locale that `centos-art.sh' script works with. +

+

The current locale information, returned by +cli_getCurrentLocale, is output from more specific to less +specific. For example, if `en_GB' locale exists in +cli_getLocales function output, the `en_GB' locale would +take precedence before `en' locale. +

+

Locale precedence selection is quite important in order to define the +locale type we use for message translations. For example, if +`en_GB' is used, we are also saying that the common language +specification for English language (i.e., `en') is no longer +used. Instead, we are using English non-common country-specific +language specifications like `en_AU', `en_BW', `en_GB', +`en_US', etc., for message translations. +

+

Use cli_getCurrentLocale function to know what current locale +information to use inside `centos-art.sh' script. +

+ +
+
Function: cli_getFilesList [LOCATION] + +
+

Output list of files to process. +

+

The cli_getFilesList function uses LOCATION variable as +source location to build a list of files just as specified by regular +expression (REGEX) global variable. Essentially, what the +cli_getFilesList function does is using find command +to look for files in the location (LOCATION) just as posix-egrep +regular expression (REGEX) specifies. +

+

If LOCATION is not specified when cli_getFilesList +function is called, the action value (ACTIONVAL) global variable +is used as location value instead. +

+

By default, if the regular expression (REGEX) global variable is +not redefined after its first definition in the cli function, +all files that match default regular expression value (i.e., +`.+') will be added to the list of files to process. Otherwise, +if you redefine the regular expression global variable after its first +definition in the cli function and before calling +cli_getFilesList function, the last value you specifed is used +instead. +

+

When you need to customize the regular expression (REGEX) global +variable value inside a function, do not redefine the global variable +(at least you be absolutly convinced you need to). Instead, set the +regular expression global variable as `local' to the function you +need a customized regular expression value for. If we don't redefine +the regular expression global variable as local to the function, or +use another name for the regular expression variable (which is not +very convenient in order to keep the amount of names to remember low), +you may experiment undesired concantenation issues that make your +regular expression to be something different from that you expect them +to be, specially if the function where you are doing the variable +redefinition is called several times during the same script execution. +

+

As result, the cli_getFilesList re-defines the value of +FILES variable with the list of files the find command +returned. As example, consider the following construction: +

+
function prefix_doSomething {
+
+    # Initialize the list of files to process.
+    local FILES=''
+
+    # Initialize location.
+    local LOCATION=/home/centos/artwork/trunk/Identity/Themes/Models/Default
+
+    # Re-define regular expression to match scalable vector graphic
+    # files only. Note how we use the global value of REGEX to build a
+    # new local REGEX value here.
+    local REGEX="${REGEX}.*\.(svgz|svg)"
+
+    # Redefine list of files to process.
+    cli_getFilesList $LOCATION
+
+    # Process list of files.
+    for FILE in $FILES;do
+        cli_printMessages "$FILE" 'AsResponseLine'
+        # Do something else here on...
+    done
+
+}
+
+
+ +
+
Function: cli_getLangCodes [FILTER] + +
+

Outputs language codes supported by `centos-art.sh' script. +

+

cli_getLangCodes function outputs a list of language codes as +defined in ISO639 standard. When FILTER is provided, +cli_getLangCodes outputs language codes that match FILTER +regular expression pattern. +

+ +
+
Function: cli_getLangName [FILTER] + +
+

Outputs language names supported by `centos-art.sh' script. +

+

cli_getLangName function reads one language locale code in the +format LL_CC and outputs the language related name as in ISO639. If +filter is specified, cli_getLangName returns the language name +that matches the locale code specified in FILTER, exactly. +

+ +
+
Function: cli_getLocales + +
+

Output locale codes supported by `centos-art.sh' script. +

+

Occasionally, you use cli_getLocales function to add locale +information in non-common country-specific language (`LL_CC') +format for those languages (e.g., `bn_IN', `pt_BR', etc.) +which locale differences cannot be solved using common language +specifications (`LL') into one unique common locale specification +(e.g., `bn', `pt', etc.). +

+ +
+
Function: cli_getRepoName NAME TYPE + +
+

Sanitate file names. +

+

Inside `centos-art.sh' script, specific functionalities rely both +in cli_getRepoName and repository file system organization to +achieve their goals. Consider cli_getRepoName function as +central place to manage file name convenctions for other functions +inside `centos-art.sh' script. +

+
Important

Important

cli_getRepoName function doesn't verify file +or directory existence, for that purpose use cli_checkFiles +function instead. +

+ +

The NAME variable contains the file name or directory name you +want to sanitate. +

+

The TYPE variable specifies what type of sanitation you want to +perform on NAME. The TYPE can be one of the following +values: +

+
+
`d'
+
`directory'
+

Sanitate directory NAMEs. +

+
`f'
+
`regular-file'
+

Sanitate regular file NAMEs. +

+
+ +

Use cli_getRepoName function to sanitate file names and +directory names before their utilization. +

+

Use cli_getRepoName when you need to change file name +convenctions inside `centos-art.sh' script. +

+

When we change file name convenctions inside cli_getRepoName +what we are really changing is the way functions interpret repository +file system organization. Notice that when we change a file name +(e.g., a function name), it is necessary to update all files where +such file name is placed on. This may require a massive substitution +inside the repository, each time we change name convenctions in the +repository (-- Removed(pxref:trunk Scripts Bash Functions Path) --, for more +information). +

+ +
+
Function: cli_getRepoStatus [LOCATION] + +
+

Request repository status. +

+

This function requests the status of a LOCATION inside the +working copy using the svn status command and returns the +first character in the output line, just as described in svn +help status. If LOCATION is not a regular file or a directory, +inside the working copy, the `centos-art.sh' script prints a +message and ends its execution. +

+

Use this function to perform verifications based a repository +LOCATION status. +

+ +
+
Function: cli_getTemporalFile NAME + +
+

Output absolute path to temporal file NAME. +

+

The cli_getTemporalFile function uses `/tmp' directory as +source location to store temporal files, the `centos-art.sh' +script name, and a random identification string to let you run more +than one `centos-art.sh' script simultaneously on the same user +session. For example, due the following temporal file defintion: +

+
cli_getTemporalFile $FILE
+
+

If FILE name is `instance.svg' and the unique random string +is `f16f7b51-ac12-4b7f-9e66-72df847f12de', the final temporal +file, built from previous temporal file definition, would be: +

+
/tmp/centos-art.sh-f16f7b51-ac12-4b7f-9e66-72df847f12de-instance.svg
+
+

When you use the cli_getTemporalFile function to create +temporal files, be sure to remove temporal files created once you've +ended up with them. For example, consider the following construction: +

+
for FILE in $FILES;do
+
+    # Initialize temporal instance of file.
+    INSTANCE=$(cli_getTemporalFile $FILE)
+
+    # Do something ... 
+
+    # Remove temporal instance of file.
+    if [[ -f $INSTANCE ]];then
+        rm $INSTANCE
+    fi
+
+done
+
+

Use the cli_getTemporalFile function whenever you need to +create temporal files inside `centos-art.sh' script. +

+ +
+
Function: cli_getThemeName + +
+

Output theme name. +

+

In order for cli_getThemeName function to extract theme name +correctly, the ACTIONVAL variable must contain a directory path +under `trunk/Identity/Themes/Motifs/' directory structure. +Otherwise, cli_getThemeName returns an empty string. +

+ +
+
Function: cli_printMessage MESSAGE [FORMAT] + +
+

Define standard output message definition supported by +`centos-art.sh' script. +

+

When FORMAT is not specified, cli_printMessage outputs +information just as it was passed in MESSAGE variable. +Otherwise, FORMAT can take one of the following values: +

+
+
`AsHeadingLine'
+

To print heading messages. +

----------------------------------------------------------------------
+$MESSAGE
+----------------------------------------------------------------------
+
+
+
`AsWarningLine'
+

To print warning messages. +

----------------------------------------------------------------------
+WARNING: $MESSAGE
+----------------------------------------------------------------------
+
+
+
`AsNoteLine'
+

To print note messages. +

----------------------------------------------------------------------
+NOTE: $MESSAGE
+----------------------------------------------------------------------

+
+
+
`AsTranslationLine'
+

To print `Translation' messages on two-columns format. +

+
+
+
`AsConfigurationLine'
+

To print `Configuration' messages on two-columns format. +

Configuration   $MESSAGE
+
+
+
`AsResponseLine'
+

To print response messages on one-column format. +

--> $MESSAGE
+
+
+
`AsRequestLine'
+

To print request messages on one-column format. Request messages +output messages with one colon (`:') and without trailing newline +(`\n') at message end. +

$MESSAGE:
+
+
+
`AsYesOrNoRequestLine'
+

To print `yes or no' request messages on one-column format. If +something different from `y' is answered (when using +en_US.UTF-8 locale), script execution ends immediatly. +

+
$MESSAGE [y/N]:
+
+

When we use `centos-art.sh' script in a locale different from +en_US.UTF-8, confirmation answer may be different from +`y'. For example, if you use es_ES.UTF-8 locale, the +confirmation question would look like: +

+
$MESSAGE [s/N]:
+
+

and the confirmation answer would be `s', as it is on Spanish +`sí' word. +

+

Definition of which confirmation word to use is set on translation +messages for your specific locale information. -- Removed(xref:trunk Scripts +Bash Functions Locale) --, for more information about locale-specific +translation messages. +

+
+
`AsToKnowMoreLine'
+

To standardize `to know more, run the following command:' +messages. When the `AsToKnowMoreLine' option is used, the +MESSAGE value should be set to "$(caller)". caller +is a Bash builtin that returns the context of the current subroutine +call. `AsToKnowMoreLine' option uses caller builtin +output to build documentation entries dynamically. +

+
----------------------------------------------------------------------
+To know more, run the following command:
+centos-art manual --read='path/to/dir'
+----------------------------------------------------------------------
+
+

Use `AsToKnowMoreLine' option after errors and for intentional +script termination. +

+
+
`AsRegularLine'
+

To standardize regular messages on one-column format. +

+

When MESSAGE contains a colon inside (e.g., `description: +message'), the cli_printMessage function outputs MESSAGE +on two-columns format. +

+
+ +

Use cli_printMessage function whenever you need to output +information from `centos-art.sh' script. +

+

2.68 The `trunk/Scripts/Bash/Cli/Functions/Locale' Directory

+ + + +

2.68.1 Goals

+ + + + + +

2.68.2 Description

+ +

This command looks for `.sh' files inside Bash directory and +extracts translatable strings from files, using xgettext +command, in order to create a portable object template +(`centos-art.sh.pot') file for them. +

+

With the `centos-art.sh.pot' file up to date, the +centos-art command removes the temporal list of files sotred +inside `/tmp' directory and checks the current language of your +user's session to create a portable object file for it, in the +location `$CLI_LANG/$CLI_LANG.po'. +

+

The CLI_LANG variable discribes the locale language used to +output messages inside centos-art command. The locale +language used inside centos-art command is taken from the +LANG environment variable. The CLI_LANG variable has the +`LL_CC' format, where `LL' is a language code from the +ISO-639 standard, and `CC' a country code from the ISO-3166 +standard. +

+

The LANG environment variable is set when you do log in to your +system. If you are using a graphical session, change language to your +native language and do login. That would set and exoprt the LANG +environment variable to the correct value. On the other side, if you +are using a text session edit your `~/.bash_profile' file to set +and export the LANG environment variable to your native locale +as defines the locale -a command output; do logout, and do +login again. +

+

At this point, the LANG environment variable has the appropriate +value you need, in order to translate centos-art.sh messages +to your native language (the one set in LANG environment +variable). +

+

With the `$CLI_LANG/$CLI_LANG.po' file up to date, the +centos-art opens it for you to update translation strings. +The centos-art command uses the value of EDITOR +environment variable to determine your favorite text editor. If no +value is defined on EDITOR, the `/usr/bin/vim' text editor +is used as default. +

+

When you finishd PO file edition and quit text editor, the +centos-art command creates the related machine object in the +location `$CLI_LANG/LC_MESSAGES/$TEXTDOMAIN.mo'. +

+

At this point, all translations you made in the PO file should be +available to your language when runing centos-art.sh script. +

+

In order to make the centos-art.sh internationalization, the +centos-art.sh script was modified as described in the +gettext info documentation (info gettext). You +can find such modifications in the following files: +

+ + + + + + +

2.68.3 Usage

+ +
+
`centos-art locale --edit'
+

Use this command to translate command-line interface output messages +in the current system locale you are using (as specified in LANG +environment variable). +

+
`centos-art locale --list'
+

Use this command to see the command-line interface locale report. +

2.70 The `trunk/Scripts/Bash/Cli/Functions/Path' Directory

+ + + +

2.70.1 Goals

+ +

This section exists to organize files related to path +functiontionality. The path functionality standardizes +movement, syncronization, branching, tagging, and general file +maintainance inside the repository. +

+ + +

2.70.2 Description

+ +

"CentOS like trees, has roots, trunk, branches, leaves and +flowers. Day by day they work together in freedom, ruled by the laws +of nature and open standards, to show the beauty of its existence." +

+ + +

2.70.2.1 Repository layout

+ +

The repository layout describes organization of files and directories +inside the repository. The repository layout provides the standard +backend required for automation scripts to work correctly. If such +layout changes unexpectedly, automation scripts may confuse themselves +and stop doing what we expect from them to do. +

+

As convenction, inside CentOS Artwork Repository, we organize files +and directories related to CentOS corporate visual identity under +three top level directories named: `trunk/', `branches/', +and `tags/'. +

+

The `trunk/' directory (see section The `trunk' Directory) organizes the main +development line of CentOS corporate visual identity. Inside +`trunk/' directory structure, the CentOS corporate visual +identity concepts are implemented using directories. There is one +directory level for each relevant concept inside the repository. The +`trunk/' directory structure is mainly used to perform +development tasks related to CentOS corporate visual identity. +

+

The `branches/' directory () oranizes +parallel development lines to `trunk/' directory. The +`branches/' directory is used to set points in time where +develpment lines are devided one from another taking separte and +idependent lives that share a common past from the point they were +devided on. The `branches/' directory is mainly used to perform +quality assurance tasks related to CentOS corporate visual identity. +

+

The `tags/' directory (see section The `tags' Directory) organizes parallel frozen +lines to `branches/' directory. The parallel frozen lines are +immutable, nothing change inside them once they has been created. The +`tags/' directory is mainly used to publish final releases of +CentOS corporate visual identity. +

+

The CentOS Artwork Repository layout is firmly grounded on a +Subversion base. Subversion (http://subversion.tigris.org) is a +version control system, which allows you to keep old versions of files +and directories (usually source code), keep a log of who, when, and +why changes occurred, etc., like CVS, RCS or SCCS. Subversion keeps a +single copy of the master sources. This copy is called the source +"repository"; it contains all the information to permit extracting +previous versions of those files at any time. +

+ + +

2.70.2.2 Repository name convenctions

+ +

Repository name convenctions help us to maintain consistency of names +inside the repository. +

+

Repository name convenctions are applied to files and directories +inside the repository layout. As convenction, inside the repository +layout, file names are all written in lowercase +(`01-welcome.png', `splash.png', `anaconda_header.png', +etc.) and directory names are all written capitalized (e.g., +`Identity', `Themes', `Motifs', `TreeFlower', +etc.). +

+

Repository name convenctions are implemented inside the +cli_getRepoName function of `centos-art.sh' script. With +cli_getRepoName function we reduce the amount of commands and +convenctions to remember, concentrating them in just one single place +to look for fixes and improvements. +

+ + +

2.70.2.3 Repository work flow

+ +

Repository work flow describes the steps and time intervals used to +produce CentOS corporate visual identity inside CentOS Artwork +Repository. +

+

To illustrate repository work flow let's consider themes' development +cycle. +

+

Initially, we start working themes on their trunk development line +(e.g., `trunk/Identity/Themes/Motifs/TreeFlower/'), here we +organize information that cannot be produced automatically (i.e., +background images, concepts, color information, screenshots, etc.). +

+

Later, when theme trunk development line is considered "ready" for +implementation (e.g., all required backgrounds have been designed), +we create a branch for it (e.g., +`branches/Identity/Themes/Motifs/TreeFlower/1/'). Once the +branch has been created, we forget that branch and continue working +the trunk development line while others (e.g., an artwork quality +assurance team) test the new branch for tunning it up. +

+

Once the branch has been tunned up, and considered "ready" for +release, it is freezed under `tags/' directory (e.g., +`tags/Identity/Themes/Motifs/TreeFower/1.0/') for packagers, +webmasters, promoters, and anyone who needs images from that CentOS +theme the tag was created for. +

+

Both branches and tags, inside CentOS Artwork Repository, use +numerical values to identify themselves under the same location. +Branches start at one (i.e., `1') and increment one unit for each +branch created from the same trunk development line. Tags start at +zero (i.e., `0') and increment one unit for each tag created from +the same branch development line. +

+
Convenction

Convenction

Do not freeze trunk development lines using tags +directly. If you think you need to freeze a trunk development line, +create a branch for it and then freeze that branch instead. +

+ +

The trunk development line may introduce problems we cannot see +immediatly. Certainly, the high changable nature of trunk development +line complicates finding and fixing such problems. On the other hand, +the branched development lines provide a more predictable area where +only fixes/corrections to current content are commited up to +repository. +

+

If others find and fix bugs inside the branched development line, we +could merge such changes/experiences back to trunk development line +(not visversa) in order for future branches, created from trunk, to +benefit. +

+

Time intervals used to create branches and tags may vary, just as +different needs may arrive. For example, consider the release schema +of CentOS distribution: one major release every 2 years, security +updates every 6 months, support for 7 years long. Each time a CentOS +distribution is released, specially if it is a major release, there is +a theme need in order to cover CentOS distribution artwork +requirements. At this point, is where CentOS Artwork Repository comes +up to scene. +

+

Before releasing a new major release of CentOS distribution we create +a branch for one of several theme development lines available inside +the CentOS Artwork Repository, perform quality assurance on it, and +later, freeze that branch using tags. Once a the theme branch has been +frozen (under `tags/' directory), CentOS Packagers (the persons +whom build CentOS distribution) can use that frozen branch as source +location to fulfill CentOS distribution artwork needs. The same +applies to CentOS Webmasters (the persons whom build CentOS websites), +and any other visual manifestation required by the project. +

+ + +

2.70.2.4 Parallel directories

+ +

Inside CentOS Artwork Repository, parallel directories are simple +directory entries built from a common parent directory and placed in a +location different to that, the common parent directory is placed on. +Parallel directories are useful to create branches, tags, +translations, documentation, pre-rendering configuration script, and +similar directory structures. +

+

Parallel directories take their structure from one unique parent +directory. Inside CentOS Artwork Repository, this unique parent +directory is under `trunk/Identity' location. The +`trunk/Identity' location must be considered the reference for +whatever information you plan to create inside the repository. +

+

In some circumstances, parallel directories may be created removing +uncommon information from their paths. Uncommon path information +refers to those directory levels in the path which are not common for +other parallel directories. For example, when rendering +`trunk/Identity/Themes/Motifs/TreeFlower/Distro' directory +structure, the `centos-art.sh' script removes the +`Motifs/TreeFlower/' directory levels from path, in order to +build the parallel directory used to retrived translations, and +pre-rendering configuration scripts required by render +functionality. +

+

Another example of parallel directory is the documentation structure +created by manual functionality. This time, +`centos-art.sh' script uses parallel directory information with +uncommon directory levels to build the documentation entry required by +Texinfo documentation system, inside the repository. +

+

Othertimes, parallel directories may add uncommon information to their +paths. This is the case we use to create branches and tags. When we +create branches and tags, a numerical identifier is added to parallel +directory structure path. The place where the numerical identifier is +set on is relevant to corporate visual identity structure and should +be carefully considered where it will be. +

+

When one parent directory changes, all their related parallel +directories need to be changed too. This is required in order for +parallel directories to retain their relation with the parent +directory structure. In the other hand, parallel directories should +never be modified under no reason but to satisfy the relation to their +parent directory structure. Liberal change of parallel directories +may suppresses the conceptual idea they were initially created for; +and certainly, things may stop working the way they should do. +

+ + +

2.70.2.5 Syncronizing path information

+ +

Parallel directories are very useful to keep repository organized but +introduce some complications. For instance, consider what would +happen to functionalities like manual (`trunk Scripts Bash +Functions Manual') that rely on parent directory structures to create +documentation entries (using parallel directory structures) if one of +those parent directory structures suddenly changes after the +documentation entry has been already created for it? +

+

In such cases, functionalities like manual may confuse +themselves if path information is not updated to reflect the relation +with its parent directory. Such functionalities work with parent +directory structure as reference; if a parent directory changes, the +functionalities dont't even note it because they work with the last +parent directory structure available in the repository, no matter what +it is. +

+

In the specific case of documentation (the manual +functionality), the problem mentioned above provokes that older parent +directories, already documented, remain inside documentation directory +structures as long as you get your hands into the documentation +directory structure (`trunk/Manuals') and change what must be +changed to match the new parent directory structure. +

+

There is no immediate way for manual, and similar +functionalities that use parent directories as reference, to know when +and how directory movements take place inside the repository. Such +information is available only when the file movement itself takes +place inside the repository. So, is there, at the moment of moving +files, when we need to syncronize parallel directories with their +unique parent directory structure. +

+
Warning

Warning

There is not support for URL reference inside +`centos-art.sh' script. The `centos-art.sh' script is +designed to work with local files inside the working copy only. +

+ +

As CentOS Artwork Repository is built over a version control system, +file movements inside the repository are considered repository +changes. In order for these repository changes to be versioned, we +need to, firstly, add changes into the version control system, commit +them, and later, perform movement actions using version control system +commands. This configuration makes possible for everyone to know about +changes details inside the repository; and if needed, revert or update +them back to a previous revision. +

+

Finally, once all path information has been corrected, it is time to +take care of information inside the files. For instance, considere +what would happen if you make a reference to a documentation node, and +later the documentation node you refere to is deleted. That would make +Texinfo to produce error messages at export time. So, the +`centos-art.sh' script needs to know when such changes happen, in +a way they could be noted and handled without producing errors. +

+ + +

2.70.2.6 What is the right place to store it?

+ +

Occasionly, you may find that new corporate visual identity components +need to be added to the repository. If that is your case, the first +question you need to ask yourself, before start to create directories +blindly all over, is: What is the right place to store it? +

+

The CentOS Community different free support vains (see: +http://wiki.centos.org/GettingHelp) are the best place to find +answers to your question, but going there with hands empty is not good +idea. It may give the impression you don't really care about. Instead, +consider the following suggestions to find your own comprehension and +so, make your propositions based on it. +

+

When we are looking for the correct place to store new files, to bear +in mind the corporate visual identity structure used inside the CentOS +Artwork Repository (see section The `trunk/Identity' Directory) would be probaly the best +advice we could offer, the rest is just matter of choosing appropriate +names. To illustrate this desition process let's consider the +`trunk/Identity/Themes/Motifs/TreeFlower' directory as example. +It is the trunk development line of TreeFlower artistic motif. +Artistic motifs are considered part of themes, which in turn are +considered part of CentOS corporate visual identity. +

+

When building parent directory structures, you may find that reaching +an acceptable location may take some time, and as it uses to happen +most of time; once you've find it, that may be not a definite +solution. There are many concepts that you need to play with, in +order to find a result that match the conceptual idea you try to +implement in the new directory location. To know which these concepts +are, split the location in words and read its documentation entry from +less specific to more specific. +

+

For example, the `trunk/Identity/Themes/Motifs/TreeFlower' +location evolved through several months of contant work and there is +no certain it won't change in the future, even it fixes quite well the +concept we are trying to implement. The concepts used in +`trunk/Identity/Themes/Distro/Motifs/TreeFlower' location are +described in the following commands, respectively: +

+
centos-art manual --read=turnk/
+centos-art manual --read=turnk/Identity/
+centos-art manual --read=turnk/Identity/Themes/
+centos-art manual --read=turnk/Identity/Themes/Motifs/
+centos-art manual --read=turnk/Identity/Themes/Motifs/TreeFlower/
+
+

Other location concepts can be found similary as we did above, just +change the location we used above by the one you are trying to know +concepts for. +

+ + +

2.70.3 Usage

+ +
+
centos-art path --copy='SRC' --to='DST'
+
+

Copy `SRC' to `DST' and schedule `DST' for +addition (with history). In this command, `SRC' and `DST' +are both working copy (WC) entries. +

+
+
centos-art path --delete='SRC'
+
+

Delete `DST'. In order for this command to work the file or +directory you intend to delete should be under version control first. +In this command, `SRC' is a working copy (WC) entry. +

+
+

2.71 The `trunk/Scripts/Bash/Cli/Functions/Render' Directory

+ +

The render functionality exists to produce both identity and +translation files on different levels of information (i.e., different +languages, release numbers, architectures, etc.). +

+

The render functionality relies on "renderable directory +structures" to produce files. Renderable directory structures can be +either "identity directory structures" or "translation directory +structures" with special directories inside. +

+ + +

2.71.1 Renderable identity directory structures

+ +

Renderable identity directory structures are the starting point of +identity rendition. Whenever we want to render a component of CentOS +corporate visual identity, we need to point `centos-art.sh' to a +renderable identity directory structure. If such renderable identity +directory structure doesn't exist, then it is good time to create it. +

+

Inside the working copy, one renderable identity directory structures +represents one visual manifestation of CentOS corporate visual +identity, or said differently, each visual manifestation of CentOS +corporate visual identity should have one renderable identity +directory structure. +

+

Inside renderable identity directory structures, `centos-art.sh' +can render both image-based and text-based files. Specification of +whether a renderable identity directory structure produces image-based +or text-based content is a configuration action that takes place in +the pre-rendition configuration script of that renderable identity +directory structure. +

+

Inside renderable identity directory structures, content production is +organized in different configurations. A content production +configuration is a unique combination of the components that make an +identity directory structure renderable. One content production +configuration does one thing only (e.g., to produce untranslated +images), but it can be extended (e.g., adding translation files) to +achieve different needs (e.g., to produce translated images). +

+ + +

2.71.1.1 Design template without translation

+ +

The design template without translation configuration is based on a +renderable identity directory structure with an empty translation +directory structure. In this configuration, one design template +produces one untranslated file. Both design templates and final +untranslated files share the same file name, but they differ one +another in file-type and file-extension. +

+

For example, to produce images without translations (there is no much +use in producing text-based files without translations), consider the +following configuration: +

+
+
One renderable identity directory structure:
+
+

In this example we used `Identity/Path/To/Dir' as the identity +component we want to produce untranslated images for. Identity +components can be either under `trunk/' or `branches/' +directory structure. +

+

The identity component (i.e., `Identity/Path/To/Dir', in this +case) is also the bond component we use to connect the identity +directory structures with their respective auxiliar directories (i.e., +translation directory structres and pre-rendition configuration +structures). The bond component is the path convenction that +`centos-art.sh' uses to know where to look for related +translations, configuration scripts and whatever auxiliar thing a +renderable directory structure may need to have. +

+
      | The bond component
+      |----------------->|
+trunk/Identity/Path/To/Dir  <-- Renderable identity directory structure.
+|-- Tpl                     <-- Design template directory.
+|   `-- file.svg            <-- Design template file.
+`-- Img                     <-- Directory used to store final files.
+    `-- file.png            <-- Final image-based file produced from
+                                design template file.
+
+

Inside design template directory, design template files are based on +SVG (Scalable Vector Graphics) and use the extension +.svg. Design template files can be organized using several +directory levels to create a simple but extensible configuration, +specially if translated images are not required. +

+

In order for SVG (Scalable Vector Graphics) files to be +considered "design template" files, they should be placed under the +design template directory and to have set a CENTOSARTWORK +object id inside. +

+

The CENTOSARTWORK word itself is a convenction name we use to +define which object/design area, inside a design template, the +`centos-art.sh' script will use to export as +PNG (Portable Network Graphic) image at rendition time. +Whithout such object id specification, the `centos-art.sh' script +cannot know what object/design area you (as designer) want to export +as PNG (Portable Network Graphic) image file. +

+
info

Note

At rendition time, the content of `Img/' directory +structure is produced by `centos-art.sh' automatically. +

+ +

When a renderable identity directory structure is configured to +produce image-based content, `centos-art.sh' produces +PNG (Portable Network Graphics) files with the .png +extension. Once the base image format has been produced, it is +possible for `centos-art.sh' to use it in order to automatically +create other image formats that may be needed (-- Removed(pxref:trunk Scripts +Bash Functions Render Config) --). +

+

Inside the working copy, you can find an example of "design template +without translation" configuration at `trunk/Identity/Models/'. +

+

See section The `trunk/Identity' Directory, for more information. +

+
+
One translation directory structure:
+
+

In order for an identity entry to be considered an identity renderable +directory structure, it should have a translation entry. The content +of the translation entry is relevant to determine how to process the +identity renderable directory entry. +

+

If the translation entry is empty (i.e., there is no file inside it), +`centos-art.sh' interprets the identity renderable directory +structure as a "design templates without translation" configuration. +

+
                   | The bond component
+                   |----------------->|
+trunk/Translations/Identity/Path/To/Dir
+`-- (empty)
+
+

If the translation entry is not empty, `centos-art.sh' can +interpret the identity renderable directory structure as one of the +following configurations: "design template with translation +(one-to-one)" or "design template with translation (optimized)". +Which one of these configurations is used depends on the value +assigned to the matching list (MATCHINGLIST) variable in the +pre-rendition configuration script of the renderable identity +directory structure we are producing images for. +

+

If the matching list variable is empty (as it is by default), then +"design template with translation (one-to-one)" configuration is +used. In this configuration it is required that both design templates +and translation files have the same file names. This way, one +translation files is applied to one design template, to produce +one translated image. +

+

If the matching list variable is not empty (because you redefine it in +the pre-rendition configuration script), then "design template with +translation (optimized)" configuration is used instead. In this +configuration, design templates and translation files don't need to +have the same names since such name relationship between them is +specified in the matching list properly. +

+

-- Removed(xref:trunk Translations) --, for more information. +

+
+
One pre-rendition configuration script:
+
+

In order to make an identity directory structure renderable, a +pre-rendition configuration script should exist for it. The +pre-rendition configuration script specifies what type of rendition +does `centos-art.sh' will perform over the identity directory +structure and how does it do that. +

+
                                           | The bond component
+                                           |----------------->|
+trunk/Scripts/Bash/Functions/Render/Config/Identity/Path/To/Dir
+`-- render.conf.sh
+
+

In this configuration the pre-rendition configuration script +(`render.conf.sh') would look like the following: +

+
function render_loadConfig {
+
+    # Define rendition actions.
+    ACTIONS[0]='BASE:renderImage'
+
+}
+
+

Since translation directory structure is empty, `centos-art.sh' +assumes a "design template without translation" configuration to +produce untranslated images. +

+

To produce untranslated images, `centos-art.sh' takes one design +template and creates one temporal instance from it. Later, +`centos-art.sh' uses the temporal design template instance as +source file to export the final untranslated image. The action of +exporting images from SVG (Scalable Vector Graphics) to +PNG (Portable Network Graphics) is possible thanks to +Inkscape's command-line interface and the CENTOSARTWORK object +id we previously set inside design templates. +

+

+--v----------------------------------------------

+-------------------------------------------------
+3 | Remove design template instance.
+
+

Finally, when the untranslated image has been created, the temporal +design template instance is removed. At this point, +`centos-art.sh' takes the next design template and repeats the +whole production flow once again (design template by design template), +until all design templates be processed. +

+

-- Removed(xref:trunk Scripts Bash Functions Render Config) --, for more +information. +

+
+ + + +

2.71.1.2 Design template with translation (one-to-one)

+ +

Producing untranslated images is fine in many cases, but not always. +Sometimes it is required to produce images in different languages and +that is something that untrasnlated image production cannot achieve. +However, if we fill its empty translation entry with translation files +(one for each design template) we extend the production flow from +untranslated image production to translated image production. +

+

In order for `centos-art.sh' to produce images correctly, each +design template should have one translation file and each translation +file should have one design template. Otherwise, if there is a +missing design template or a missing translation file, +`centos-art.sh' will not produce the final image related to the +missing component. +

+

In order for `centos-art.sh' to know which is the relation +between translation files and design templates the translation +directory structure is taken as reference. For example, the +`trunk/Translations/Identity/Path/To/Dir/file.sed' translation +file does match `trunk/Identity/Path/To/Dir/Tpl/file.svg' design +template, but it doesn't match +`trunk/Identity/Path/To/Dir/File.svg' or +`trunk/Identity/Path/To/Dir/Tpl/File.svg' or +`trunk/Identity/Path/To/Dir/Tpl/SubDir/file.svg' design +templates. +

+

The pre-rendition configuration script used to produce untranslated +images is the same we use to produce translated images. There is no +need to modify it. So, as we are using the same pre-rendition +configuration script, we can say that translated image production is +somehow an extended/improved version of untranslated image production. +

+
info

Note

If we use no translation file in the translation entry +(i.e., an empty directory), `centos-art.sh' assumes the +untranslated image production. If we fill the translation entry with +translation files, `centos-art.sh' assumes the translated image +production. +

+ +

To produce final images, `centos-art.sh' applies one translation +file to one design template and produce a translated design template +instance. Later, `centos-art.sh' uses the translated template +instance to produce the translated image. Finally, when the translated +image has been produced, `centos-art.sh' removes the translated +design template instance. This production flow is repeated for each +translation file available in the translatio entry. +

2.71.1.3 Design template with translation (optimized)

+ +

Producing translated images satisfies almost all our production images +needs, but there is still a pitfall in them. In order to produce +translated images as in the "one-to-one" configuration describes +previously, it is required that one translation file has one design +template. That's useful in many cases, but what would happen if we +need to apply many different translation files to the same design +template? Should we have to duplicate the same design template file +for each translation file, in order to satisfy the "one-to-one" +relation? What if we need to assign translation files to design +templates arbitrarily? +

+

Certenly, that's something the "one-to-one" configuration cannot +handle. So, that's why we had to "optimize" it. The optimized +configuration consists on using a matching list (MATCHINGLIST) +variable that specifies the relationship between translation files and +design templates in an arbitrary way. Using such matching list between +translation files and design templates let us use as many assignment +combinations as translation files and design templates we are working +with. +

+

The MATCHINGLIST variable is set in the pre-rendition +configuration script of the component we want to produce images for. +By default, the MATCHINGLIST variable is empty which means no +matching list is used. Otherwise, if MATCHINGLIST variable has a +value different to empty value then, `centos-art.sh' interprets +the matching list in order to know how translation files are applied +to design templates. +

+

For example, consider the following configuration: +

+
+
One entry under `trunk/Identity/':
+
+

In this configuration we want to produce three images using a +paragraph-based style, controlled by `paragraph.svg' design +template; and one image using a list-based style, controlled by +`list.svg' design template. +

+
trunk/Identity/Path/To/Dir
+|-- Tpl
+|   |-- paragraph.svg
+|   `-- list.svg
+`-- Img
+    |-- 01-welcome.png
+    |-- 02-donate.png
+    |-- 03-docs.png
+    `-- 04-support.png
+
+
+
One entry under `trunk/Translations/':
+
+

In order to produce translated images we need to have one translation +file for each translated image we want to produce. Notice how +translation names do match final image file names, but how translation +names do not match design template names. When we use matching list +there is no need for translation files to match the names of design +templates, such name relation is set inside the matching list itself. +

+
trunk/Translations/Identity/Path/To/Dir
+|-- 01-welcome.sed
+|-- 02-donate.sed
+|-- 03-docs.sed
+`-- 04-support.sed
+
+
+
One entry under `trunk/trunk/Scripts/Bash/Functions/Render/Config/':
+
+

In order to produce different translated images using specific design +templates, we need to specify the relation between translation files +and design templates in a way that `centos-art.sh' could know +exactly what translation file to apply to what design template. This +relation between translation files and design templates is set using +the matching list MATCHINGLIST variable inside the pre-rendition +configuration script of the component we want to produce images for. +

+
trunk/Scripts/Bash/Functions/Render/Config/Identity/Path/To/Dir
+`-- render.conf.sh
+
+

In this configuration the pre-rendition configuration script +(`render.conf.sh') would look like the following: +

+
function render_loadConfig {
+
+    # Define rendition actions.
+    ACTIONS[0]='BASE:renderImage'
+
+    # Define matching list.
+    MATCHINGLIST="\
+    paragraph.svg:\
+        01-welcome.sed\
+        02-donate.sed\
+        04-support.sed
+    list.svg:\
+        03-docs.sed
+    "
+
+}
+
+

As result, `centos-art.sh' will produce `01-welcome.png', +`02-donate.png' and `04-support.png' using the +paragraph-based design template, but `03-docs.png' using the +list-based design template. +

+
+ + + +

2.71.1.4 Design template with translation (optimized+flexibility)

+ +

In the production models we've seen so far, there are design templates +to produce untranslated images and translation files which combiend +with design templates produce translated images. That may seems like +all our needs are covered, doesn't it? Well, it almost does. +

+

Generally, we use design templates to define how final images will +look like. Generally, each renderable directory structure has one +`Tpl/' directory where we organize design templates for that +identity component. So, we can say that there is only one unique +design template definition for each identity component; or what is the +same, said differently, identity components can be produced in one way +only, the way its own design template directory specifies. This is +not enough for theme production. It is a limitation, indeed. +

+

Initially, to create one theme, we created one renderable directory +structure for each theme component. When we found ourselves with many +themes, and components inside them, it was obvious that the same +design model was duplicated inside each theme. As design models were +independently one another, if we changed one theme's design model, +that change was useless to other themes. So, in order to reuse design +model changes, we unified design models into one common directory +structure. +

+

With design models unified in a common structure, another problem rose +up. As design models also had the visual style of theme components, +there was no difference between themes, so there was no apparent need +to have an independent theme directory structure for each different +theme. So, it was also needed to separate visual styles from design +models. +

+

At this point there are two independent worklines: one directory +structure to store design models (the final image characteristics +[i.e., dimensions, translation markers, etc.]) and one directory +structure to store visual styles (the final image visual style [i.e., +the image look and feel]). So, it is possible to handle both +different design models and different visual styles independtly one +another and later create combinations among them using +`centos-art.sh'. +

+

For example, consider the following configuration: +

+
+
One entry under `trunk/Identity/Themes/Models/':
+
+

The design model entry exists to organize design model files (similar +to design templates). Both design models and design templates are very +similar; they both should have the CENTOSARTWORK export id +present to identify the exportation area, translation marks, etc. +However, design models do use dynamic backgrounds inclusion while +design templates don't. +

+
                        THEMEMODEL | | The bond component
+                             |<----| |--------------------->|
+trunk/Identity/Themes/Models/Default/Distro/Anaconda/Progress/
+|-- paragraph.svg
+`-- list.svg
+
+

Inisde design models, dynamic backgrounds are required in order for +different artistic motifs to reuse common design models. Firstly, in +order to create dynamic backgrounds inside design models, we import a +bitmap to cover design model's background and later, update design +model's path information to replace fixed values to dynamic values. +

+
+
One entry under `trunk/Identity/Themes/Motifs/':
+
+

The artistic motif entry defines the visual style we want to produce +images for, only. Final images (i.e., those built from combining both +design models and artistic motif backrounds) are not stored here, but +under branches directory structure. In the artistic motif entry, we +only define those images that cannot be produced automatically by +`centos-art.sh' (e.g., Backgrounds, Color information, +Screenshots, etc.). +

+
                  Artistic motif name | | Artistic motif backgrounds
+                             |<-------| |-------->|

+`-- Xcf
+    `-- 510x300.xcf
+
+
+
One entry under `trunk/Translations/':
+
+

The translation entry specifies, by means of translation files, the +language-specific information we want to produce image for. When we +create the translation entry we don't use the name of neither design +model nor artistic motif, just the design model component we want to +produce images for. +

+

+
+
+
One entry under `trunk/Scripts/Bash/Functions/Render/Config/':
+
+

There is one pre-rendition configuration script for each theme +component. So, each time a theme component is rendered, its +pre-rendition configuration script is evaluated to teach +`centos-art.sh' how to render the component. +

+
trunk/Scripts/Bash/Functions/Render/Config/Identity/Themes/Distro/Anaconda/Progress/
+`-- render.conf.sh
+
+

In this configuration the pre-rendition configuration script +(`render.conf.sh') would look like the following: +

+
function render_loadConfig {
+
+    # Define rendition actions.
+    ACTIONS[0]='BASE:renderImage'
+
+    # Define matching list.
+    MATCHINGLIST="\

+        "
+
+    # Deifne theme model.
+    THEMEMODEL='Default'
+
+}
+
+
+ +

The production flow of "optimize+flexibility" configuration… +

+ +

2.71.2 Renderable translation directory structures

+ +

Translation directory structures are auxiliar structures of renderable +identity directory structures. There is one translation directory +structure for each renderable identity directory structure. Inside +translation directory structures we organize translation files used by +renderable identity directory structures that produce translated +images. Renderable identity directory structures that produce +untranslated images don't use translation files, but they do use a +translation directory structure, an empty translation directory +structure, to be precise. +

+

In order to aliviate production of translation file, we made +translation directory structures renderable adding a template +(`Tpl/') directory structure to handle common content inside +translation files. This way, we work on translation templates and +later use `centos-art.sh' to produce specific translation files +(based on translation templates) for different information (e.g., +languages, release numbers, architectures, etc.). +

+

If for some reason, translation files get far from translation +templates and translation templates become incovenient to produce such +translation files then, care should be taken to avoid replacing the +content of translation files with the content of translation templates +when `centos-art.sh' is executed to produce translation files +from translation templates. +

+

Inside renderable translation directory structures, +`centos-art.sh' can produce text-based files only. +

+ + +

2.71.3 Copying renderable directory structures

+ +

A renderable layout is formed by design models, design images, +pre-rendition configuration scripts and translations files. This way, +when we say to duplicate rendition stuff we are saying to duplicate +these four directory structures (i.e., design models, design images, +pre-rendition configuration scripts, and related translations files). +

+

When we duplicate directories, inside `trunk/Identity' directory +structure, we need to be aware of renderable layout described above +and the source location used to perform the duplication action. The +source location is relevant to centos-art.sh script in order to +determine the required auxiliar information inside directory +structures that need to be copied too (otherwise we may end up with +orphan directory structures unable to be rendered, due the absence of +required information). +

+

In order for a renderable directory structure to be valid, the new +directory structure copied should match the following conditions: +

+
    +
  1. To have a unique directory structure under +`trunk/Identity', organized by any one of the above +organizational designs above. + +
  2. To have a unique directory structure under +`trunk/Translations' to store translation files. + +
  3. To have a unique directory structure under +`trunk/Scripts/Bash/Functions/Render/Config' to set pre-rendition +configuration script. +
+ +

As convenction, the render_doCopy function uses +`trunk/Identity' directory structure as source location. Once +the `trunk/Identity' directory structure has been specified and +verified, the related path information is built from it and copied +automatically to the new location specified by FLAG_TO variable. +

+

Design templates + No translation: +

+

Command: +- centos-art render -copy=trunk/Identity/Path/To/Dir -to=trunk/Identity/NewPath/To/Dir +

+

Sources: +- trunk/Identity/Path/To/Dir +- trunk/Translations/Identity/Path/To/Dir +- trunk/Scripts/Bash/Functions/Render/Config/Identity/Path/To/Dir +

+

Targets: +- trunk/Identity/NewPath/To/Dir +- trunk/Translations/Identity/NewPath/To/Dir +- trunk/Scripts/Bash/Functions/Render/Config/Identity/NewPath/To/Dir +

+

Renderable layout 2: +

+

Command: +- centos-art render -copy=trunk/Identity/Themes/Motifs/TreeFlower \ + -to=trunk/Identity/Themes/Motifs/NewPath/To/Dir +

+

Sources: +- trunk/Identity/Themes/Motifs/TreeFlower +- trunk/Translations/Identity/Themes +- trunk/Translations/Identity/Themes/Motifs/TreeFlower +- trunk/Scripts/Bash/Functions/Render/Config/Identity/Themes +- trunk/Scripts/Bash/Functions/Render/Config/Identity/Themes/Motifs/TreeFlower +

+

Targets: +- trunk/Identity/Themes/Motifs/NewPath/To/Dir +- trunk/Translations/Identity/Themes +- trunk/Translations/Identity/Themes/Motifs/NewPath/To/Dir +- trunk/Scripts/Bash/Functions/Render/Config/Identity/Themes +- trunk/Scripts/Bash/Functions/Render/Config/Identity/Themes/Motifs/NewPath/To/Dir +

+

Notice that design models are not included in source or target +locations. This is intentional. In "Renderable layout 2", design +models live by their own, they just exist, they are there, available +for any artistic motif to use. By default `Themes/Models/Default' +design model directory structure is used, but other design models +directory structures (under Themes/Models/) can be created and used +changing the value of THEMEMODEL variable inside the pre-rendition +configuration script of the artistic motif source location you want to +produce. +

+

Notice how translations and pre-rendition configuration scripts may +both be equal in source and target. This is because such structures +are common to all artistic motifs (the default values to use when no +specific values are provided). +

+

- The common directory structures are not copied or deleted. We cannot + copy a directory structure to itself. +

+

- The common directory structures represent the default value to use + when no specific translations and/or pre-rendition configuration + script are provided inside source location. +

+

- The specific directory structures, if present, are both copiable and + removable. This is, when you perform a copy or delete action from + source, that source specific auxiliar directories are transfered in + the copy action to a new location (that specified by FLAG_TO + variable). +

+

- When translations and/or pre-rendition configuration scripts are + found inside the source directory structure, the centos-art.sh + script loads common auxiliar directories first and later specific + auxiliar directories. This way, identity rendition of source + locations can be customized idividually over the base of common + default values. +

+

- The specific auxiliar directories are optional. +

+

- The common auxiliar directories should be present always. This is, + in order to provide the information required by render functionality + (i.e., to make it functional in the more basic level of its + existence). +

+

Notice how the duplication process is done from `trunk/Identity' on, +not the oposite. If you try to duplicate a translation structure (or +similar auxiliar directory structures like pre-rendition configuration +scripts), the `trunk/Identity' for that translation is not created. +This limitation is impossed by the fact that many `trunk/Identity' +directory structures may reuse/share the same translation directory +structure. We cannot delete one translation (or similar) directory +structures while a related `trunk/Identity/' directory structure is +still in need of it. +

+

The `render_doCopy' functionality does duplicate directory structures +directly involved in rendition process only. Once such directories +have been duplicated, the functionality stops thereat. +

2.72 The `trunk/Scripts/Bash/Cli/Functions/Render/Config' Directory

+ + + +

2.72.1 Goals

+ +

The `trunk/Scripts/Bash/Config' directory exists to oraganize +pre-rendering configuration scripts. +

+ + +

2.72.2 Description

+ +

Pre-rendering configuration scripts let you customize the way +centos-art.sh script renders identity and translation +repository entries. Pre-rendering configuration scripts are +`render.conf.sh' files with render_loadConfig function +definition inside. +

+

There is one `render.conf.sh' file for each pre-rendering +configuration entry. Pre-rendering configuration entries can be based +both on identity and translation repository entires. Pre-rendering +configuration entries are required for each identity entry, but not +for translation entries. +

+ + +

2.72.2.1 The `render.conf.sh' identity model

+ +

Inside CentOS Artwork Repository, we consider identity entries to all +directories under `trunk/Identity' directory. Identity entries can be +image-based or text-based. When you render image-based identity +entries you need to use image-based pre-rendering configuration +scripts. Likewise, when you render text-based identity entries you +need to use text-based pre-rendering configuration scripts. +

+

Inside identity pre-rendering configuration scripts, image-based +pre-rendering configuration scripts look like the following: +

+
#!/bin/bash
+
+function render_loadConfig {
+
+    # Define rendering actions.
+    ACTIONS[0]='BASE:renderImage'
+    ACTIONS[1]='POST:renderFormats: tif xpm pdf ppm'
+
+}
+
+

Inside identity pre-rendering configuration scripts, text-based +pre-rendering configuration scripts look like the following: +

+
#!/bin/bash
+
+function render_loadConfig {
+
+    # Define rendering actions.
+    ACTIONS[0]='BASE:renderText'
+    ACTIONS[1]='POST:formatText: --width=70 --uniform-spacing'
+
+}
+
+

When using identity pre-rendering configuration scripts, you can +extend both image-based and text-based pre-rendering configuration +scripts using image-based and text-based post-rendering actions, +respectively. +

+ + +

2.72.2.2 The `render.conf.sh' translation model

+ +

Translation pre-rendering configuration scripts take precedence before +default translation rendering action. Translation pre-rendering +actions are useful when default translation rendering action do not +fit itself to translation entry rendering requirements. +

+ + +

2.72.2.3 The `render.conf.sh' rendering actions

+ +

Inside both image-based and text-based identity pre-rendering +configuration scripts, we use the `ACTIONS' array variable to +define the way centos-art.sh script performs identity +rendering. Identity rendering is organized by one `BASE' action, +and optional `POST' and `LAST' rendering actions. +

+

The `BASE' action specifies what kind of rendering does the +centos-art.sh script will perform with the files related to +the pre-rendering configuration script. The `BASE' action is +required. Possible values to `BASE' action are either +`renderImage' or `renderText' only. +

+

To specify the `BASE' action you need to set the `BASE:' +string followed by one of the possible values. For example, if you +want to render images, consider the following definition of +`BASE' action: +

+
ACTIONS[0]='BASE:renderImage'
+
+

Only one `BASE' action must be specified. If more than one +`BASE' action is specified, the last one is used. If no +`BASE' action is specified at all, an error is triggered and the +centos-art.sh script ends its execution. +

+

The `POST' action specifies which action to apply for +each file rendered (at the rendering time). This action is optional. +You can set many different `POST' actions to apply many different +actions over the same already rendered file. Possible values to +`POST' action are `renderFormats', `renderSyslinux', +`renderGrub', etc. +

+

To specify the `POST' action, you need to use set the +`POST:' followed by the function name of the action you want to +perform. The exact form depends on your needs. For example, consider +the following example to produce `xpm', `jpg', and +`tif' images, based on already rendered `png' image, and +also organize the produced files in directories named as their own +extensions: +

+
ACTIONS[0]='BASE:renderImage'
+ACTIONS[1]='POST:renderFormats: xpm jpg tif'
+ACTIONS[2]='POST:groupByFormat: png xpm jpg tif'
+
+

In the previous example, file organization takes place at the moment +of rendering, just after producing the `png' base file and before +going to the next file in the list of files to render. If you don't +want to organized the produced files in directories named as their own +extensions, just remove the `POST:groupByFormat' action line: +

+
ACTIONS[0]='BASE:renderImage'
+ACTIONS[1]='POST:renderFormats: xpm jpg tif'
+
+

The `LAST' action specifies which actions to apply once the last +file in the list of files to process has been rendered. The +`LAST' action is optional. Possible values for `LAST' +actions may be `groupByFormat', `renderGdmTgz', etc. +

+
info

Note

-- Removed(xref:trunk Scripts Bash Functions Render) --, to know more +about possible values for `BASE', `POST' and `LAST' +action definitions. +

+ +

To specify the `LAST' action, you need to set the `LAST:' +string followed by the function name of the action you want to +perform. For example, consider the following example if you want to +render all files first and organize them later: +

+
ACTIONS[0]='BASE:renderImage'
+ACTIONS[1]='POST:renderFormats: xpm jpg tif'
+ACTIONS[2]='LAST:groupByformat: png xpm jpg tif'
+
+ + +

2.72.3 Usage

+ +

Use the following commands to administer both identity and translation +pre-rendering configuration scripts: +

+
+
`centos-art config --create='path/to/dir/''
+
+

Use this command to create `path/to/dir' related pre-rendering +configuration script. +

+
+
`centos-art config --edit='path/to/dir/''
+
+

Use this command to edit `path/to/dir' related pre-rendering +configuration script. +

+
+
`centos-art config --read='path/to/dir/''
+
+

Use this command to read `path/to/dir' related pre-rendering +configuration script. +

+
+
`centos-art config --remove='path/to/dir/''
+
+

Use this command to remove `path/to/dir' related pre-rendering +configuration script. +

+
+
+ +

In the commands above, `path/to/dir' refers to one renderable +directory path under `trunk/Identity' or +`trunk/Translations' structures only. +

2.73 The `trunk/Scripts/Bash/Cli/Functions/Shell' Directory

+ + + +

2.73.1 Goals

+ +

This section exists to organize files related to shell +functionality of `centos-art.sh' script. +

+ + +

2.73.2 Description

+ +

The shell functionality of `centos-art.sh' script helps +you to maintain bash scripts inside repository. For example, suppose +you've created many functionalities for `centos-art.sh' script, +and you want to use a common copyright and license note for +consistency in all your script files. If you have a bunch of files, +doing this one by one wouldn't be a big deal. In contrast, if the +amount of files grows, updating the copyright and license note for all +of them would be a task rather tedious. The shell functionality +exists to solve maintainance tasks just as the one previously +mentioned. +

+

When you use shell functionality to update copyright inside +script files, it is required that your script files contain (at least) +the following top commentary structure: +

+
+
 1| #!/bin/bash
+ 2| #
+ 3| # doSomething.sh -- The function description goes here.
+ 4| # 
+ 5| # Copyright
+ 6| #
+ 7| # ...
+ 8| #
+ 9| # ----------------------------------------------------------------------
+10| # $Id$
+11| # ----------------------------------------------------------------------
+12|
+13| function doSomething {
+14|     
+15| }
+
+

Figure 2.4: The functions script base comment structure + +

+

Relevant lines in the above structure are lines from 5 to 9. +Everything else in the file is left immutable. +

+

When you are updating copyright through shell +functionality, the `centos-art.sh' script replaces everything +in-between line 5 --the first one matching `^# Copyright .+$' +string-- and line 9--the first long dash separator matching `^# +-+$'-- with the content of copyright template instance. +

+
Caution

Caution

Be sure to add the long dash separator that matches +`^# -+$' regular expression before the function +definition. Otherwise, if the `Copyright' line is present but no +long dash separator exists, `centos-art.sh' will remove anything +in-between the `Copyright' line and the end of file. This way you +may lost your function definitions entirely. +

+ +

The copyright template instance is created from one copyright template +stored in the `Config/tpl_forCopyright.sed' file. The template +instance is created once, and later removed when no longer needed. At +this moment, when template instance is created, the +`centos-art.sh' script takes advantage of automation in order to +set copyright full name and date dynamically. +

+

When you use shell functionality to update copyright, the first +thing `shell' functionality does is requesting copyright +information to user, and later, if values were left empty (i.e., no +value was typed before pressing RET key), the `shell' +functionality uses its own default values. +

+

When shell functionality uses its own default values, the final +copyright note looks like the following: +

+
+
 1| #!/bin/bash
+ 2| #
+ 3| # doSomthing.sh -- The function description goes here.

Figure 2.5: The function script comment example + +

+

Relevant lines in the above structure are lines from 5 to 22. Pay +attention how the copyright line was built, and how the license was +added into the top comment where previously was just three dots. +Everything else in the file was left immutable. +

+

To change copyright information (i.e., full name or year information), +run the shell functionality over the root directory containing +the script files you want to update copyright in and enter the +appropriate information when it be requested. You can run the +shell functionality as many times as you need to. +

+

To change copyright license (i.e., the text in-between lines 7 and +20), you need to edit the `Config/tpl_forCopyright.sed' file, set +the appropriate information, and run the shell functionality +once again for changes to take effect over the files you specify. +

2.73.3 Usage

+ +
+
centos-art sh --update-copyright='path/to/dir'
+
centos-art sh --update-copyright='path/to/dir' --filter='regex'
+

Use these commands to update copyright information in `.sh' files +under `path/to/dir' directory. +

+
+ +

When you provide `--filter='regex'' argument, the list of files +to process is reduced as specified in `regex' regular expression. +Inside `centos-art.sh' script, the `regex' regular +expression is used in combination with find command to look +for files matching the regular expression path pattern. +

+
Warning

Warning

In order for `regex' regular expression to match +a file, the `regex' regular expresion must match the whole file +path not just the file name. +

+ +

For example, if you want to match all `render.conf.sh' files +inside `path/to/dir', use the .+/render.conf regular +expression. Later, `centos-art.sh' script uses this value inside +^$REGEX\.sh$ expression in order to build the final regular +expression (i.e., ^.+/render.conf\.sh$) that is evaluated +against available file paths inside the list of files to process. +

+

Exceptionally, when you provide `--filter='regex'' in the way +that `regex', appended to `path/to/dir/' (i.e. +`path/to/dir/regex'), matches a regular file; the +`centos-art.sh' script uses the file matching as only file in the +list of files to process. +

2.74 The `trunk/Scripts/Bash/Cli/Functions/Svg' Directory

+ + + +

2.74.1 Goals

+ +

This section exists to organize files related to svg +functionality of `centos-art.sh' script. +

+ + +

2.74.2 Description

+ +

The svg functionality of `centos-art.sh' script helps you +to maintain scalable vector graphics (SVG) inside repository. For +example, suppose you've been working in CentOS default design models +under `trunk/Identity/Themes/Models/', and you want to set common +metadata to all of them, and later remove all unused SVG defintions +from `*.svg' files. Doing so file by file may be a tedious task, +so the `centos-art.sh' script provides the svg +functionality to aid you maintain such actions. +

+ + + +

2.74.2.1 Metadata maintainance

+ +

The metadata used is defined by Inkscape 0.46 using the SVG standard +markup. The `centos-art.sh' script replaces everything +in-between <metadata and </metadata> tags with a +predefined metadata template we've set for this purpose. +

+

The metadata template was created using the metadata information of a +file which, using Inkscape 0.46, all metadata fields were set. This +created a complete markup representation of how SVG metadata would +look like. Later, we replaced every single static value with a +translation marker in the form `=SOMETEXT=', where +SOMETEXT is the name of its main opening tag. Later, we +transform the metadata template into a sed replacement set of commads +escaping new lines at the end of each line. +

+

With metadata template in place, the `centos-art.sh' script uses +it to create a metadata template instance for the file being processed +currently. The metadata template instance contains the metadata +portion of sed replacement commands with translation markers already +traduced. In this action, instance creation, is where we take +advantage of automation and generate metadata values like title, date, +keywords, source, identifier, and relation dynamically, based on the +file path `centos-art.sh' script is currently creating metadata +information for. +

+

With metadata template instance in place, the `centos-art.sh' +script uses it to replace real values inside all `.svg' files +under the current location you're running the `centos-art.sh' +script on. Default behaviour is to ask user to enter each metadatum +required, one by one. If user leaves metadatum empty, by pressing +RET key, `centos-art.sh' uses its default value. +

+

The `centos-art.sh' script modifies the following metadata: +

+
+
`Title'
+

Name by which this document is formally known. If no value is set +here, `centos-art.sh' script uses the file name as title. +

+
+
`Date'
+

Date associated with the creation of this document (YYYY-MM-DD). If no +value is set here, `centos-art.sh' script uses the current date +information as in date +%Y-%m-%d. +

+
+
`Creator'
+

Name of entity primarily responsible for making the content of this +document. If no value is set here, `centos-art.sh' script uses +the string `The CentOS Project'. +

+
+
`Rights'
+

Name of entity with rights to the intellectual Property of this +document. If no value is set here, `centos-art.sh' script uses +the string `The CentOS Project'. +

+
+
`Publisher'
+

Name of entity responsible for making this document available. If no +value is set here, `centos-art.sh' script uses the string +`The CentOS Project'. +

+
+
`Identifier'
+

Unique URI to reference this document. If no value is set here, +`centos-art.sh' script uses the current file path to build the +related url that points to current file location inside repository +central server. +

+
+
`Source'
+

Unique URI to reference the source of this document. If no value is +set here, `centos-art.sh' script uses current file path to build +the related url that points to current file location inside repository +central server. +

+
+
`Relation'
+

Unique URI to a related document. If no value is set here, +`centos-art.sh' script uses current file path to build the +related url that points to current file location inside repository +central server. +

+
+
`Language'
+

Two-letter language tag with optional subtags for the language of this +document. (e.g. `en-GB'). If no value is set here, +`centos-art.sh' script uses the current locale information as in +cli_getCurrentLocale function. +

+
+
`Keywords'
+

The topic of this document as comma-separated key words, prhases, or +classifications. If no value is set here, `centos-art.sh' script +uses file path to build +

+
+
`Coverage'
+

Extent or scope of this document. If no value is set here, +`centos-art.sh' script uses the string `The CentOS Project'. +

+
+
`Description'
+

Description about the document. If no value is set here, +`centos-art.sh' script uses uses empty value as default. +

+
+
`Contributors'
+

People that contributes in the creation/maintainance of the document. +If no value is set here, `centos-art.sh' script uses uses empty +value as default. +

+
+ +

The `License' metadatum is not set as a choise, by now. It is +fixed Creative Common Attribution Share-Alike 3.0 License. This is done in order to +grant license consistency among all SVG files we manage inside CentOS +Artwork Repository. +

+ + + +

2.74.2.2 Unused definitions

+ +

Many of the no-longer-used gradients, patterns, and markers (more +precisely, those which you edited manually) remain in the +corresponding palettes and can be reused for new objects. However if +you want to optimize your document, use the `Vacuum Defs' command +in `File' menu. It will remove any gradients, patterns, or +markers which are not used by anything in the document, making the +file smaller. +

+

If you have one or two couple of files, removing unused definitions +using the graphical interface may be enough to you. In contrast, if +you have dozens or even houndreds of scalable vector graphics files to +maintain it is not a fun task to use the graphical interface to remove +unused definitions editing those files one by one. +

+

To remove unused definitions from several scalable vector graphics +files, the `centos-art.sh' script uses Inkscape command-line +interface, specifically with the `--vaccum-defs' option. +

+ + +

2.74.3 Usage

+ +
+
centos-art svg --update-metadata='path/to/dir'
+
centos-art svg --update-metadata='path/to/dir' --filter='regex'
+

Use these commands to update metadata information to `.svg' files +under `path/to/dir' directory. +

+
+
centos-art svg --vacuum-defs='path/to/dir'
+
centos-art svg --vacuum-defs='path/to/dir' --filter='regex'
+

Use these commands to remove unused definitions inside `.svg' +files under `path/to/dir' directory. +

+
+ +

When you provide `--filter='regex'' argument, the list of files +to process is reduced as specified in `regex' regular expression. +Inside `centos-art.sh' script, the `regex' regular +expression is used in combination with find command to look +for files matching the regular expression path pattern. +

+
Warning

Warning

In order for `regex' regular expression to match +a file, the `regex' regular expresion must match the whole file +path not just the file name. +

+ +

For example, if you want to match all `summary.svg' files inside +`path/to/dir', use the .+/summary regular expression. +Later, `centos-art.sh' script uses this value inside +^$REGEX\.svg$ expression in order to build the final regular +expression (i.e., ^.+/summary\.svg$) that is evaluated against +available file paths inside the list of files to process. +

+

Exceptionally, when you provide `--filter='regex'' in the way +that `regex', appended to `path/to/dir/' (i.e. +`path/to/dir/regex'), matches a regular file; the +`centos-art.sh' script uses the file matching as only file in the +list of files to process. +

2.75 The `trunk/Scripts/Bash/Cli/Functions/Verify' Directory

+ + + +

2.75.1 Goals

+ +

This section exists to organize files related to `centos-art.sh' +script `verify' functionality. The `verify' +functionality of `centos-art.sh' script helps you to verify the +workstation configuration you are planning to use as host for your +working copy of CentOS Artwork Repository. +

+ + +

2.75.2 Description

+ +

The first time you download CentOS Artwork Repository you need to +configure your workstation in order to use `centos-art.sh' +script. These preliminar configurations are based mainly on auxiliar +RPM packages installation, symbolic links creations, and environment +variables definitions. The `verify' functionality of +`centos-art.sh' script guides you through this preliminar +configuration process. +

+

If this is the first time you run `centos-art.sh' script, the +appropriate way to use its `verify' functionality is not using +the `centos-art.sh' script directly, but the absolute path to +centos-art.sh script instead (i.e., +`~/artwork/trunk/Scripts/Bash/centos-art.sh'). This is necessary +because `centos-art' symbolic link, under `~/bin/' +directory, has not been created yet. +

+ + +

2.75.2.1 Packages

+ +

Installation of auxiliar RPM packages provides the software required +to manipulate files inside the repository (e.g., image files, +documentation files, translation files, script files, etc.). Most of +RPM packages centos-art.sh script uses are shipped with +CentOS distribution, and can be installed from CentOS base repository. +The only exception is `inkscape', the package we use to +manipulate SVG files. The `inkscape' package is not inside +CentOS distribution so it needs to be installed from third party +repositories. +

+
info

Note

Configuration of third party repositories inside CentOS +distribution is described in CentOS wiki, specifically in the +following URL: +http://wiki.centos.org/AdditionalResources/Repositories +

+ +

Before installing packages, the `centos-art.sh' script uses +sudo to request root privileges to execute yum +installation functionality. If your user isn't defined as a +privileged user--at least to run yum commands-- inside +`/etc/sudoers' configuration file, you will not be able to +perform package installation tasks as set in `centos-art.sh' +script `verify' functionality. +

+

Setting sudo privileges to users is an administrative task you have to +do by yourself. If you don't have experience with sudo +command, please read its man page running the command: man +sudo. This reading will be very useful, and with some practice, you +will be able to configure your users to have sudo +privileges. +

+ + +

2.75.2.2 Links

+ +

Creation of symbolic links helps us to alternate between different +implementations of `centos-art.sh' script-line (e.g., +`centos-art.sh', for Bash implementation; `centos-art.py', +for Python implementation; `centos-art.pl', for Perl +implementation; and so on for other implementations). The +`centos-art.sh' script-line definition takes place inside your +personal binary (`~/bin/') directory in order to make the script +implementation --the one that `centos-art' links to-- available +to PATH environment variable. +

+

Creation of symbolic links helps us to reuse components from repository +working copy. For example, color information files maintained inside +your working copy must never be duplicated inside program-specific +configuration directories that uses them in your workstation (e.g., +Gimp, Inkscape, etc.). Instead, a symbolic link must be created for +each one of them, from program-specific configuration directories to +files in the working copy. In this configuration, when someone +commits changes to color information files up to central repository, +they--the changes committed-- will be immediatly available to your +programs the next time you update your working copy --the place +inside your workstation those color information files are stored--. +

+

Creation of symbolic links helps us to make `centos-art.sh' +script functionalities available outside `trunk/' repository +directory structure, but at its same level in repository tree. This is +useful if you need to use the "render" functionality of +centos-art.sh under `branches/' repository directory +structure as you usually do inside `trunk/' repository directory +structure. As consequence of this configuration, automation scripts +cannot be branched under `branches/Scripts' directory structure. +

+ + +

2.75.2.3 Environment variables

+ +

Definition of environemnt variables helps us to set default values to +our user session life. The user session environment variable defintion +takes place in the user's `~/.bash_profile' file. The +`verify' functionality of `centos-art.sh' script doesn't +modify your `~/.bash_profile' file. +

+

The `verify' functionality of `centos-art.sh' script +evaluates the following environment variables: +

+
+
EDITOR
+

Default text editor. +

+

The `centos-art.sh' script uses default text EDITOR to edit +pre-commit subversion messages, translation files, configuration +files, script files, and similar text-based files. +

+

If EDITOR environment variable is not set, `centos-art.sh' +script uses `/usr/bin/vim' as default text editor. Otherwise, the +following values are recognized by `centos-art.sh' script: +

+
    +
  • `/usr/bin/vim' +
  • `/usr/bin/emacs' +
  • `/usr/bin/nano' +
+ +

If no one of these values is set in EDITOR environment variable, +`centos-art.sh' uses `/usr/bin/vim' text editor by default. +

+
+
TEXTDOMAIN
+
+

Default domain used to retrieve translated messages. This variable is +set in `initFunctions.sh' and shouldn't be changed. +

+
+
TEXTDOMAINDIR
+
+

Default directory used to retrieve translated messages. This variable +is set in `initFunctions.sh' and shouldn't be changed. +

+
+
LANG
+
+

Default locale information. +

+

This variable is initially set in the configuration process of CentOS +distribution installer (i.e., Anaconda), specifically in the +`Language' step; or once installed using the +system-config-language tool. +

+

The `centos-art.sh' script uses the LANG environment +variable to know in which language the script messages are printed +out. +

+
+
TZ
+
+

Default time zone representation. +

+

This variable is initially set in the configuration process of CentOS +distribution installer (i.e., Anaconda), specifically in the +`Date and time' step; or once installed using the +system-config-date tool. +

+

The `centos-art.sh' script doesn't use the TZ environment +variable information at all. Instead, this variable is used by the +system shell to show the time information according to your phisical +location on planet Earth. +

+

Inside your computer, the time information is firstly set in the BIOS +clock (which may need correction), and later in the configuration +process of CentOS distribution installer (or later, by any of the +related configuration tools inside CentOS distribution). Generally, +setting time information is a straight-forward task and configuration +tools available do cover most relevant location. However, if you need +a time precision not provided by the configuration tools available +inside CentOS distribution then, using TZ variable may be +necessary. +

+
Convenction

Convenction

In order to keep changes syncronized between +central repository and its working copies: configure both repository +server and workstations (i.e., the place where each working copy is +set on) to use Coordinated Universal Time (UTC) as base time +representation. Later, correct the time information for your specific +location using time zone correction. +

+ +

The format of TZ environment variable is described in +`tzset(3)' manual page. +

+
+
+ + + +

2.75.3 Usage

+ +
+
centos-art verify --packages
+
+

Verify required packages your workstation needs in order to run the +`centos-art.sh' script correctly. If there are missing packages, +the `centos-art.sh' script asks you to confirm their +installation. When installing packages, the `centos-art.sh' +script uses the yum application in order to achieve the +task. +

+

In case all packages required by `centos-art.sh' script are +already installed in your workstation, the message `The required +packages are already installed.' is output for you to know. +

+
+
centos-art verify --links
+
+

Verify required links your workstation needs in order to run the +centos-art command correctly. If any required link is missing, the +centos-art.sh script asks you to confirm their installation. +To install required links, the centos-art.sh script uses the +ln command. +

+

In case all links required by `centos-art.sh' script are already +created in your workstation, the message `The required links are +already installed.' is output for you to know. +

+

In case a regular file exists with the same name of a required link, +the `centos-art.sh' script outputs the `Already exists as +regular file.' message when listing required links that will be +installed. Of course, as there is already a regular file where must be +a link, no link is created. In such cases the `centos-art.sh' +script will fall into a continue installation request for that missing +link. To end this continue request you can answer `No', or +remove the existent regular file to let `centos-art.sh' script +install the link on its place. +

+
+
centos-art verify --environment
+
centos-art verify --environment --filter='regex'
+
+

Output a brief description of environment variables used by +`centos-art.sh' script. +

+

If `--filter' option is provided, output is reduced as defined in +the `regex' regular expression value. If `--filter' option +is specified but `regex' value is not, the `centos-art.sh' +script outputs information as if `--filter' option had not been +provided at all. +
