2.52 The <tt>`trunk/Scripts/Bash/Cli/Functions'</tt> Directory

ee1f37
ee1f37
063806
063806

2.52.1 Goals

ee1f37
063806

The <tt>`trunk/Scripts/Bash/Functions'</tt> directory exists to organize

063806
<tt>`centos-art.sh'</tt> specific functionalities.
063806

ee1f37
063806
063806

2.52.2 Description

ee1f37
063806

The specific functions of <tt>`centos-art.sh'</tt> script are designed

063806
with "Software Toolbox" philosophy (see (coreutils.info)Toolbox introduction) in mind: each program "should do one
063806
thing well".  Inside <tt>`centos-art.sh'</tt> script, each specific
063806
functionality is considered a program that should do one thing well.
063806
Of course, if you find that they still don't do it, feel free to
063806
improve them in order for them to do so.
063806

063806

The specific functions of <tt>`centos-art.sh'</tt> script are organized

063806
inside specific directories under <tt>`trunk/Scripts/Bash/Functions'</tt>
063806
location. Each specific function directory should be named as the
063806
function it represents, with the first letter in uppercase. For
063806
example, if the function name is render, the specific function
063806
directory for it would be <samp>`trunk/Scripts/Bash/Functions/Render'</samp>.
063806

063806

To better understand how specific functions of <tt>`centos-art.sh'</tt>

063806
script are designed, lets create one function which only goal is to
063806
output different kind of greetings to your screen.
063806

063806

When we create specific functions for <tt>`centos-art.sh'</tt> script it

063806
is crucial to know what these functions will do exactly and if there
063806
is any function that already does what we intend to do. If there is no
063806
one, it is good time to create them then. Otherwise, if
063806
functionalities already available don't do what you exactly expect,
063806
contact their authors and work together to improve them.

It is also worth to know what global functions and variables do we

063806
have available inside <tt>`centos-art.sh'</tt> script, so advantage can be
063806
taken from them. Global variables are defined inside global function
063806
scripts. Global functions scripts are stored immediatly under
063806
<tt>`trunk/Scripts/Bash/Functions'</tt> directory, in files begining with
063806
<samp>`cli'</samp> prefix.
063806

063806

OK, let's begin with our functionality example.

063806

063806

What function name do we use? Well, lets use greet. Note that

063806
<samp>`hello'</samp> word is not a verb; but an expression, a kind of
063806
greeting, an interjection specifically. In contrast, <samp>`greet'</samp> is a
063806
verb and describes what we do when we say <samp>`Hello!'</samp>, <samp>`Hi!'</samp>,
063806
and similar expressions.
063806

063806

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

063806

063806
Name: greet
063806
Path: trunk/Scripts/Bash/Functions/Greet
063806
File: trunk/Scripts/Bash/Functions/Greet/greet.sh
063806
063806

The <tt>`greet.sh'</tt> function script is the first file

063806
<tt>`centos-art.sh'</tt> script loads when the <samp>`greet'</samp> functionality
063806
is called using commands like <samp>`centos-art greet --hello='World''</samp>.
063806
The <tt>`greet.sh'</tt> function script contains the greet function
063806
definition. 
063806

063806

Inside <tt>`centos-art.sh'</tt> script, as convenction, each function

063806
script has one top commentary, followed by one blank line, and then
063806
one function defintion below it only.
063806

063806

Inside <tt>`centos-art.sh'</tt> script functions, top commentaries have

063806
the following components: the functionality description, one-line for
063806
copyright note with your personal information,  the license under
063806
which the function source code is released --the <tt>`centos-art.sh'</tt>
063806
script is released as GPL, so do all its functions--, the $Id$
063806
keyword of Subversion is later expanded by svn propset
063806
command.
063806

063806

In our greet function example, top commentary for

063806
<tt>`greet.sh'</tt> function script would look like the following:
063806

063806
#!/bin/bash
063806
#
063806
# greet.sh -- This function outputs different kind of greetings to
063806
# your screen. Use this function to understand how centos-art.sh
063806
# script specific functionalities work.

063806
063806

After top commentary, separated by one blank line, the greet

063806
function definition would look like the following:
063806

063806
function greet {
063806
063806
    # Define global variables.
063806
063806
    # Define command-line interface.
063806
    greet_getActions
063806
063806
}
063806
063806

The first definition inside greet function, are global

063806
variables that will be available along greet function execution
063806
environment. This time we didn't use global variable definitions for
063806
greet function execution environment, so we left that section
063806
empty.
063806

063806

Later, we call greet_getActions function to define the

063806
command-line interface of greet functionality. The command-line
063806
interface of greet functionality defines what and how actions
063806
are performed, based on arguments combination passed to
063806
<tt>`centos-art.sh'</tt> script.
063806

063806
function greet_getActions {
063806
063806
    case "$ACTIONNAM" in
063806
063806
        --hello )
063806
            greet_doHello
063806
            ;;
063806
063806
        --bye )
063806
            greet_doBye
063806
            ;;
063806
063806
        * )
063806
            cli_printMessage "`gettext "The option provided is not valid."`"
063806
            cli_printMessage "$(caller)" 'AsToKnowMoreLine'
063806
063806
    esac
063806
063806
}
063806
063806

The ACTIONNAM global variable is defined in <tt>`cli.sh'</tt>

063806
function script and contains the value passed before the equal sign
063806
(i.e., <samp>`='</samp>) in the second command-line argument of
063806
<tt>`centos-art.sh'</tt> script. For example, if the second command-line
063806
argument is <samp>`--hello='World''</samp>, the value of ACTIONNAM
063806
variable would be <samp>`--hello'</samp>.  Using this configuration let us
063806
deside which action to perform based on the action name passed to
063806
<tt>`centos-art.sh'</tt> script as second argument. 
063806

063806

The greet function definition makes available two valid

063806
greetings through <samp>`--hello'</samp> and <samp>`--bye'</samp> options.  If no
063806
one of them is provided as second command-line argument, the <samp>`*'</samp>
063806
case is evaluated instead. 
063806

063806

The <samp>`*'</samp> case and its two lines further on should always be

063806
present in <tt>`_getActions.sh'</tt> function scripts, no matter what
063806
specific functionality you are creating. This convenction helps the
063806
user to find out documentation about current functionality in use,
063806
when no valid action is provided.
063806

063806

The greet_doHello and greet_doBye function definitions

063806
are the core of greet specific functionality.  In such function
063806
definitions we set what our greet function really does: to
063806
output different kinds of greetings.
063806

063806
function greet_doHello {
063806
063806
    cli_printMessage "`gettext "Hello"` $ACTIONVAL"
063806
063806
}
063806
063806

The greet_doHello function definition is stored in

063806
<tt>`greet_doHello.sh'</tt> function script. 
063806

063806
function greet_doBye {
063806
063806
    cli_printMessage "`gettext "Goodbye"` $ACTIONVAL"
063806
063806
}
063806
063806

The greet_doBye function definition is stored in the

063806
<tt>`greet_doBye.sh'</tt> function script. 
063806

063806

Both <tt>`greet_doHello.sh'</tt> and <tt>`greet_doBye.sh'</tt> function

063806
scripts are stored inside greet function directory path (i.e.
063806
<tt>`trunk/Scripts/Bash/Functions/Greet'</tt>).
063806

063806

The ACTIONVAL global variable is defined in <tt>`cli.sh'</tt>

063806
function script and contains the value passed after the equal sign
063806
(i.e., <samp>`='</samp>) in the second command-line argument of
063806
<tt>`centos-art.sh'</tt> script. For example, if the second command-line
063806
argument is <samp>`--hello='World''</samp>, the value of ACTIONVAL
063806
variable would be <samp>`World'</samp> without quotes.
063806

063806

Let's see how greet specific functionality files are organzied

063806
under greet function directory. To see file organization we use
063806
the tree command:
063806

063806
trunk/Scripts/Bash/Functions/Greet
063806
|-- greet_doBye.sh
063806
|-- greet_doHello.sh
063806
|-- greet_getActions.sh
063806
`-- greet.sh
063806
063806

To try the greet specific functionality we've just created,

063806
pass the function name (i.e., <samp>`greet'</samp>) as first argument to
063806
<tt>`centos-art.sh'</tt> script, and any of the valid options as second
063806
argument. Some examples are illustrated below:
063806

063806
[centos@projects ~]$ centos-art greet --hello='World'
063806
Hello World
063806
[centos@projects ~]$ centos-art greet --bye='World'
063806
Goodbye World
063806
[centos@projects ~]$ 
063806
063806

The word <samp>`World'</samp> in the examples above can be anything. In fact,

063806
change it to have a little fun.
063806

063806

Now that we have a specific function that works as we expect, it is

063806
time to document it.  To document greet specific functionality,
063806
we use its directory path and the manual functionality
063806
(-- Removed(pxref:trunk Scripts Bash Functions Manual) --) of <tt>`centos-art.sh'</tt>
063806
script, just as the following command illustrates: 
063806

063806
centos-art manual --edit=trunk/Scripts/Bash/Functions/Greet
063806
063806

To have a well documented function helps user to understand how your

063806
function really works, and how it should be used.  When no valid
063806
action is passed to a function, the <tt>`centos-art.sh'</tt> script uses
063806
the function documentation entry as vehicle to communicate which the
063806
valid functions are. When no documentation entry exists for a
063806
function, the <tt>`centos-art.sh'</tt> script informs that no
063806
documentation entry exists for such function and requests user to
063806
create it right at that time.
063806

063806

Now that we have documented our function, it is time to translate its

063806
output messages to different languages. To translate specific
063806
functionality output messages to different languages we use the
063806
locale functionality (-- Removed(pxref:trunk Scripts Bash Functions
063806
Locale) --) of <tt>`centos-art.sh'</tt> script, just as the following command
063806
illustrates:
063806

063806
centos-art locale --edit
063806
063806
Warning

Warning

To translate output messages in different languages,

063806
your system locale information --as in LANG environment
063806
variable-- must be set to that locale you want to produce translated
063806
messages for. For example, if you want to produce translated messages
063806
for Spanish language, your system locale information must be set to
063806
<samp>`es_ES.UTF-8'</samp>, or similar, first.
063806

063806
063806

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

063806

063806

In greet function example we've described so far, we only use

063806
cli_printMessage global function in action specific function
063806
definitions in order to print messages, but more interesting things
063806
can be achieved inside action specific function definitions.  For
063806
example, if you pass a directory path as action value in second
063806
argument, you could retrive a list of files from therein, and process
063806
them. If the list of files turns too long or you just want to control
063806
which files to process, you could add the third argument in the form
063806
<samp>`--filter='regex''</samp> and reduce the amount of files to process
063806
using a regular expression pattern.
063806

063806

The greet function described in this section may serve you as

063806
an introduction to understand how specific functionalities work inside
063806
<tt>`centos-art.sh'</tt> script. With some of luck this introduction will
063806
also serve you as motivation to create your own <tt>`centos-art.sh'</tt>
063806
script specific functionalities.
063806

063806

By the way, the greet functionality doesn't exist inside

063806
<tt>`centos-art.sh'</tt> script yet. Would you like to create it?

063806
063806
063806
063806

2.52.3.1 Global variables

063806
063806

The following global variables of <tt>`centos-art.sh'</tt> script, are

063806
available for you to use inside specific functions:
063806

063806
063806
<u>Variable:</u> TEXTDOMAIN
063806
063806
063806

Default domain used to retrieve translated messages. This value is set

063806
in <tt>`initFunctions.sh'</tt> and shouldn't be changed.
063806

063806
063806
063806
<u>Variable:</u> TEXTDOMAINDIR
063806
063806
063806

Default directory used to retrieve translated messages. This value is

063806
set in <tt>`initFunctions.sh'</tt> and shouldn't be changed.
063806

063806
063806
063806
<u>Variable:</u> FUNCNAM
063806
063806
063806

Define function name.

063806

063806

Function names associate sets of actions. There is one set of actions

063806
for each unique function name inside <tt>`centos-art.sh'</tt> script.
063806

063806

Dunction names are passed as first argument in <tt>`centos-art.sh'</tt>

063806
command-line interface. For example, in the command <samp>`centos-art
063806
render --entry=path/to/dir --filter=regex'</samp>, the ACTION passed to
063806
<tt>`centos-art.sh'</tt> script is <samp>`render'</samp>.
063806

063806

When first argument is not provided, the <tt>`centos-art.sh'</tt> script

063806
immediatly ends its execution.
063806

063806
063806
063806
<u>Variable:</u> FUNCDIR
063806
063806
063806
063806
063806
063806
<u>Variable:</u> FUNCDIRNAME
063806
063806
063806
063806
063806
063806
<u>Variable:</u> FUNCSCRIPT
063806
063806
063806
063806
063806
063806
<u>Variable:</u> FUNCCONFIG
063806
063806
063806
063806
063806
063806
<u>Variable:</u> ACTIONNAM
063806
063806
063806

Define action name.

063806

063806

Each action name identifies an specific action to perform, inside an

063806
specific function.
063806

063806

Action name names aare passed as second argument in

063806
<tt>`centos-art.sh'</tt> command-line interface. For example, in the
063806
command <samp>`centos-art render --entry=path/to/dir --filter=regex'</samp>,
063806
the ACTIONNAM passed to <tt>`centos-art.sh'</tt> script is
063806
<samp>`--entry'</samp>.
063806

063806

When second argument is not provided, the <tt>`centos-art.sh'</tt> script

063806
immediatly ends its execution.
063806

063806
063806
063806
<u>Variable:</u> ACTIONVAL
063806
063806
063806

Define action value.

063806

063806

Action values are associated to just one action name. Action values

063806
contain the working copy entry over which its associated action will be
063806
performed in.  Working copy entries can be files or directories inside
063806
the working copy.
063806

063806
063806
063806
<u>Variable:</u> REGEX
063806
063806
063806

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

063806
to process.
063806

063806

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

063806
files.
063806

063806

Functions that need to build a list of files to process use the option

063806
<samp>`--filter'</samp> to redefine REGEX variable default value, and
063806
so, control the amount of files to process.
063806

ee1f37
063806
063806
<u>Variable:</u> ARGUMENTS
063806
063806
063806

Define optional arguments.

063806

063806

Optional arguments, inside <tt>`centos-art.sh'</tt> script, are considered

063806
as all command-line arguments passed to <tt>`centos-art.sh'</tt> script,
063806
from third argument position on. For example, in the command
063806
<samp>`centos-art render --entry=path/to/dir --filter=regex'</samp> , the
063806
optional arguments are from <samp>`--filter=regex'</samp> argument on.
063806

063806

Optional arguments are parsed using getopt command through

063806
the following base construction: 
063806

063806
# Define short options we want to support.
063806
local ARGSS=""
063806
063806
# Define long options we want to support.
063806
local ARGSL="filter:,to:"
ee1f37
063806
# Parse arguments using getopt(1) command parser.
063806
cli_doParseArguments
ee1f37
063806
# Reset positional parameters using output from (getopt) argument
063806
# parser.
063806
eval set -- "$ARGUMENTS"
063806
063806
# Define action to take for each option passed.
063806
while true; do
063806
    case "$1" in
063806
        --filter )
063806
            REGEX="$2" 
063806
            shift 2
063806
            ;;
063806
        --to )
063806
            TARGET="$2" 
063806
            shift 2
063806
            ;;
063806
        * )
063806
            break
063806
    esac
063806
done
063806
063806

Optional arguments provide support to command options inside

063806
<tt>`centos-art.sh'</tt> script. For instance, consider the Subversion
063806
(svn) command, where there are many options (e.g.,
063806
<samp>`copy'</samp>, <samp>`delete'</samp>, <samp>`move'</samp>, etc), and inside each
063806
option there are several modifiers (e.g., <samp>`--revision'</samp>,
063806
<samp>`--message'</samp>, <samp>`--username'</samp>, etc.) that can be combined one
063806
another in their short or long variants. 
063806

063806

The ARGUMENTS variable is used to store arguments passed from

063806
command-line for later use inside <tt>`centos-art.sh'</tt> script. Storing
063806
arguments is specially useful when we want to run a command with some
063806
specific options from them. Consider the following command:
063806

063806
centos-art path --copy=SOURCE --to=TARGET --message="The commit message goes here." --username='johndoe'
063806
063806

In the above command, the <samp>`--message'</samp>, and <samp>`--username'</samp>

063806
options are specific to svn copy command. In such cases,
063806
options are not interpreted by <tt>`centos-art.sh'</tt> script itself.
063806
Instead, the <tt>`centos-art.sh'</tt> script uses getopt to
063806
retrive them and store them in the ARGUMENTS variable for later
063806
use, as described in the following command:
063806

063806
# Build subversion command to duplicate locations inside the
063806
# workstation.
063806
eval svn copy $SOURCE $TARGET --quiet $ARGUMENTS
063806
063806

When getopt parses ARGUMENTS, we may use short options

063806
(e.g., <samp>`-m'</samp>) or long options (e.g., <samp>`--message'</samp>). When
063806
we use short options, arguments are separated by one space from the
063806
option (e.g., <samp>`-m 'This is a commit message.''</samp>).  When we use
063806
long options arguments are separated by an equal sign (<samp>`='</samp>)
063806
(e.g., <samp>`--message='This is a commit message''</samp>).
063806

063806

In order for getopt to parse ARGUMENTS correctly, it

063806
is required to provide the short and long definition of options that
063806
will be passed or at least supported by the command performing the
063806
final action the function script exists for.
063806

063806

As convenction, inside <tt>`centos-art.sh'</tt> script, short option

063806
definitions are set in the ARGSS variable; and long option
063806
definitions are set in the ARGSL variable.
063806

063806

When you define short and long options, it may be needed to define

063806
which of these option arguments are required and which not. To define
063806
an option argument as required, you need to set one colon <samp>`:'</samp>
063806
after the option definition (e.g., <samp>`-o m: -l message:'</samp>).  On
063806
the other hand, to define an option argument as not required, you need
063806
to set two colons <samp>`::'</samp> after the option definition (e.g.,
063806
<samp>`-o m:: -l message::'</samp>).
063806

063806
063806
063806
<u>Variable:</u> EDITOR
063806
063806
063806

Default text editor.

063806

063806

The <tt>`centos-art.sh'</tt> script uses default text EDITOR to edit

063806
pre-commit subversion messages, translation files, configuration
063806
files, script files, and similar text-based files.
063806

063806

If EDITOR environment variable is not set, <tt>`centos-art.sh'</tt>

063806
script uses <tt>`/usr/bin/vim'</tt> as default text editor. Otherwise, the
063806
following values are recognized by <tt>`centos-art.sh'</tt> script:
063806

b9dbd3
    063806
  • <tt>`/usr/bin/vim'</tt>
  • 063806
  • <tt>`/usr/bin/emacs'</tt>
  • 063806
  • <tt>`/usr/bin/nano'</tt>
  • b9dbd3
    ee1f37
    063806

    If no one of these values is set in EDITOR environment variable,

    063806
    <tt>`centos-art.sh'</tt> uses <tt>`/usr/bin/vim'</tt> text editor by default. 
    063806

    2.52.3.2 Global functions

    063806
    063806

    Function scripts stored directly under

    063806
    <tt>`trunk/Scripts/Bash/Functions/'</tt> directory are used to define
    063806
    global functions.  Global functions can be used inside action specific
    063806
    functionalities and or even be reused inside themselves. This section
    063806
    provides introductory information to global functions you can use
    063806
    inside <tt>`centos-art.sh'</tt> script.
    063806

    063806
    063806
    <u>Function:</u> cli_checkActionArguments
    063806
    063806
    063806

    Validate action value (ACTIONVAL) variable.

    063806

    063806

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

    063806

    063806
      063806
    1. Path to one directory inside the local working copy,
    2. 063806
    3. Path to one file inside the local working copy,
    4. 063806
      063806
      063806

      If another value different from that specified above is passed to

      063806
      action value variable, the <tt>`centos-art.sh'</tt> script prints an error
      063806
      message and ends script execution.
      063806

      063806
      063806
      063806
      <u>Function:</u> cli_checkFiles FILE [TYPE]
      063806
      063806
      063806

      Verify file existence.

      063806

      063806

      cli_checkFiles receives a FILE absolute path and performs

      063806
      file verification as specified in TYPE.  When TYPE is not
      063806
      specified, cli_checkFiles verifies FILE existence, no
      063806
      matter what kind of file it be.  If TYPE is specified, use one
      063806
      of the following values:
      063806

      063806
      063806
      <samp>`d'</samp>
      063806
      <samp>`directory'</samp>
      063806

      Ends script execution if FILE is not a directory.

      063806

      063806

      When you verify directories with cli_checkFiles, if directory doesn't

      063806
      exist, <tt>`centos-art.sh'</tt> script asks you for confirmation in order
      063806
      to create that directory. If you answer positively,
      063806
      <tt>`centos-art.sh'</tt> script creates that directory and continues
      063806
      script flows normally. Otherwise, if you answer negatively,
      063806
      <tt>`centos-art.sh'</tt> ends script execution with an error and
      063806
      documentation message.
      063806

      063806
      063806
      <samp>`f'</samp>
      063806
      <samp>`regular-file'</samp>
      063806

      Ends script execution if FILE is not a regular file.

      063806

      063806
      <samp>`h'</samp>
      063806
      <samp>`symbolic-link'</samp>
      063806

      Ends script execution if FILE is not a symbolic link.

      063806

      063806
      <samp>`x'</samp>
      063806
      <samp>`execution'</samp>
      063806

      Ends script execution if FILE is not executable.

      063806

      063806
      <samp>`fh'</samp>
      063806

      Ends script execution if FILE is neither a regular file nor a

      063806
      symbolic link.
      063806

      063806
      <samp>`fd'</samp>
      063806

      Ends script execution if FILE is neither a regular file nor a

      063806
      directory.
      063806

      063806
      <samp>`isInWorkingCopy'</samp>
      063806

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

      063806

      063806
      063806
      063806

      As default behaviour, if FILE passes all verifications,

      063806
      <tt>`centos-art.sh'</tt> script continues with its normal flow. 
      063806

      063806
      063806
      063806
      <u>Function:</u> cli_commitRepoChanges [LOCATION]
      063806
      063806
      063806

      Syncronize changes between repository and working copy.

      063806

      063806

      The cli_commitRepoChanges function brings changes from the

      063806
      central repository down to the working copy--using svn
      063806
      update--, checks the working copy changes--using svn
      063806
      status command--, prints status report--using both svn
      063806
      update and svn status commands output, and finally, commits
      063806
      recent changes from the working copy up to the repository--using
      063806
      svn commit command--.
      063806

      063806

      Previous to commit the working copy changes up to the central

      063806
      repository, the cli_commitRepoChanges function asks you to
      063806
      verify changes--using svn diff command--, and later,
      063806
      another confirmation question is shown to be sure you really want to
      063806
      commit changes up to central repository.
      063806

      063806

      If LOCATION argument is not specified, the value of

      063806
      ACTIONVAL variable is used as reference instead.

      <u>Function:</u> cli_doParseArgumentsReDef $@

      063806

      Initialize/reset arguments (ARGUMENTS) global variable using

      063806
      positional parameters variable ($@) as reference.
      063806

      063806

      When we work inside function definitions, positional parameters are

      063806
      reset to the last function definition positional parameters.  If you
      063806
      need to redefine positional parameters from one specific function, you
      063806
      need to call cli_doParseArgumentsReDef with the positional
      063806
      parameters variable ($@), set as first argument, to that
      063806
      specific function you want to redefine positional parameters at.
      063806

      063806
      063806
      063806
      <u>Function:</u> cli_getArguments
      063806
      063806
      063806

      Initialize function name (FUNCNAM), action name

      063806
      (ACTIONNAM), and action value (ACTIONVAL) global
      063806
      variables, using positional parameters passed in $@ variable.
      063806

      063806

      The cli_getArguments function is called from cli.sh

      063806
      function script, using cli function positional parameters
      063806
      (i.e., the positional parameters passed as arguments in the
      063806
      command-line) as first function argument. 
      063806

      063806

      Once command-line positional parameters are accesible to

      063806
      <tt>`centos-art.sh'</tt> script execution evironment,
      063806
      cli_getArguments uses regular expression to retrive
      063806
      action variables from first and second argument. The first argument
      063806
      defines the value used as function name (FUNCNAM), and the
      063806
      second argument defines both values used as action name
      063806
      (ACTIONNAM) and action value (ACTIONVAL), respectively.
      063806

      063806

      The first argument is a word in lower case. This word specifies the

      063806
      name of the functionality you want to use (e.g., <samp>`render'</samp> to
      063806
      render images, <samp>`manual'</samp> to work on documentation, and so on.)
      063806

      063806

      The second argument has a long option style (e.g.,

      063806
      <samp>`--option=value'</samp>). The <samp>`--option'</samp> represents the action name
      063806
      (ACTIONNAM), and the characters inbetween the equal sign
      063806
      (<samp>`='</samp>) and the first space character, are considered as the action
      063806
      value (ACTIONVAL). In order to provide action values with space
      063806
      characters inbetween you need to enclose action value with quotes like
      063806
      in <samp>`--option='This is long value with spaces inbetween''</samp>.
      063806
      Generally, action values are used to specify paths over which the
      063806
      action name acts on.
      063806

      063806

      Once action related variables (i.e., FUNCNAM, ACTIONNAM,

      063806
      and ACTIONVAL) are defined and validated,
      063806
      cli_getArguments shifts the positional arguments to remove the
      063806
      first two arguments passed (i.e., those used to retrive action related
      063806
      variables) and redefine the arguments (ARGUMENTS) global
      063806
      variable with the new positional parameters information.
      063806

      063806

      <u>Function:</u> cli_getFunctions
      063806
      063806
      063806

      Initialize funtionalities supported by <tt>`centos-art.sh'</tt> script.

      063806

      063806

      Functionalities supported by <tt>`centos-art.sh'</tt> script are organized

      063806
      in functionality directories under
      063806
      <tt>`trunk/Scripts/Bash/Functions/'</tt> directory. Each functionality
      063806
      directory stores function scripts to the functionality such directory
      063806
      was created for. Function scripts contain function definitions.
      063806
      Function definitions contain several commands focused on achieving one
      063806
      specific task only (i.e., the one such functionality was created for).
      063806

      063806

      In order for <tt>`centos-art.sh'</tt> script to recognize a functionality,

      063806
      such functionality needs to be stored under
      063806
      <tt>`trunk/Scripts/Bash/Functions/'</tt> in a directory written
      063806
      capitalized (i.e., the whole name is written in lowercase except the
      063806
      first character which is in uppercase). The directory where one
      063806
      specific functionality is stored is known as the <samp>`functionality
      063806
      directory'</samp>. 
      063806

      063806

      Inside each functionality directory, the functionalty itself is

      063806
      implemented through function scripts. Function scripts are organized
      063806
      in files independently one another and written in <samp>`camelCase'</samp>
      063806
      format with the function name as prefix.  Separation between prefix
      063806
      and description is done using underscore (<samp>`_'</samp>) character.
      063806

      063806

      In order for <tt>`centos-art.sh'</tt> script to load functionalities

      063806
      correctly, function definition inside function scripts should be set
      063806
      using the <samp>`function'</samp> reserved word, just as in the following
      063806
      example:
      063806

      063806
      function prefix_doSomething {
      063806
      063806
          # Do something here...
      063806
      063806
      }
      063806
      063806

      The above function definition is just a convenction we use, in order

      063806
      to make identification of function names easier read and automate by
      063806
      <tt>`centos-art.sh'</tt> script initialization commands, once
      063806
      <tt>`centos-art.sh'</tt> script determines which functionality directory
      063806
      to use.  Specifically, in order to initialize and export functions,
      063806
      <tt>`centos-art.sh'</tt> script executes all function scripts inside the
      063806
      functionality directory, and later grep on them using a
      063806
      regular expression pattern, where the <samp>`function'</samp> reserved word is
      063806
      used as reference to retrive the function names and export them to
      063806
      <tt>`centos-art.sh'</tt> script execution environment, and so, make
      063806
      function definitions --from function scripts inside the functionality
      063806
      directory-- available for further calls.
      063806

      063806

      If the functionality specified in the command-line first argument

      063806
      doesn't have a functionality directory, <tt>`centos-art.sh'</tt> script
      063806
      considers the functionality provided in the command-line as invalid
      063806
      functionality and immediatly stops script execution with an error
      063806
      message.
      063806

      063806

      In order to keep visual consistency among function scripts, please

      063806
      consider using the following function script design model as template
      063806
      for your own function scripts:
      063806

      063806
      #!/bin/bash
      063806
      #
      063806
      # prefix_doSomething.sh -- This function illustrates function scripts
      063806
      # design model you can use to create your own function scripts inside
      063806
      # centos-art.sh script.

      <u>Function:</u> cli_getCountryCodes [FILTER]
      063806
      063806

      Output country codes supported by <tt>`centos-art.sh'</tt> script.

      063806

      063806

      The cli_getCountryCodes function outputs a list with country

      063806
      codes as defined in ISO3166 standard. When FILTER is provided,
      063806
      cli_getCountryCodes outputs country codes that match
      063806
      FILTER regular expression pattern.
      063806

      <u>Function:</u> cli_getCountryName [FILTER]

      Outputs country name supported by <tt>`centos-art.sh'</tt> script.

      063806

      063806

      The cli_getCountryName function reads one language locale code

      063806
      in the format LL_CC and outputs the name of its related country as in
      063806
      ISO3166. If filter is specified, cli_getCountryName returns the
      063806
      country name that matches the locale code specified in FILTER,
      063806
      exactly.
      063806

      <u>Function:</u> cli_getCurrentLocale

      063806

      Output current locale used by <tt>`centos-art.sh'</tt> script.

      063806

      063806

      The cli_getCurrentLocale function uses LANG environment

      063806
      variable to build a locale pattern that is later applied to
      063806
      cli_getLocales function output in order to return the current
      063806
      locale that <tt>`centos-art.sh'</tt> script works with. 
      063806

      063806

      The current locale information, returned by

      063806
      cli_getCurrentLocale, is output from more specific to less
      063806
      specific. For example, if <samp>`en_GB'</samp> locale exists in
      063806
      cli_getLocales function output, the <samp>`en_GB'</samp> locale would
      063806
      take precedence before <samp>`en'</samp> locale.
      063806

      063806

      Locale precedence selection is quite important in order to define the

      063806
      locale type we use for message translations. For example, if
      063806
      <samp>`en_GB'</samp> is used, we are also saying that the common language
      063806
      specification for English language (i.e., <samp>`en'</samp>) is no longer
      063806
      used. Instead, we are using English non-common country-specific
      063806
      language specifications like <samp>`en_AU'</samp>, <samp>`en_BW'</samp>, <samp>`en_GB'</samp>,
      063806
      <samp>`en_US'</samp>, etc., for message translations.  
      063806

      063806

      Use cli_getCurrentLocale function to know what current locale

      063806
      information to use inside <tt>`centos-art.sh'</tt> script.

      <u>Function:</u> cli_getFilesList [LOCATION]
      063806
      063806
      063806

      Output list of files to process.

      063806

      063806

      The cli_getFilesList function uses LOCATION variable as

      063806
      source location to build a list of files just as specified by regular
      063806
      expression (REGEX) global variable. Essentially, what the
      063806
      cli_getFilesList function does is using find command
      063806
      to look for files in the location (LOCATION) just as posix-egrep
      063806
      regular expression (REGEX) specifies. 
      063806

      063806

      If LOCATION is not specified when cli_getFilesList

      063806
      function is called, the action value (ACTIONVAL) global variable
      063806
      is used as location value instead.
      063806

      063806

      By default, if the regular expression (REGEX) global variable is

      063806
      not redefined after its first definition in the cli function,
      063806
      all files that match default regular expression value (i.e.,
      063806
      <samp>`.+'</samp>) will be added to the list of files to process. Otherwise,
      063806
      if you redefine the regular expression global variable after its first
      063806
      definition in the cli function and before calling
      063806
      cli_getFilesList function, the last value you specifed is used
      063806
      instead.
      063806

      063806

      When you need to customize the regular expression (REGEX) global

      063806
      variable value inside a function, do not redefine the global variable
      063806
      (at least you be absolutly convinced you need to).  Instead, set the
      063806
      regular expression global variable as <samp>`local'</samp> to the function you
      063806
      need a customized regular expression value for.  If we don't redefine
      063806
      the regular expression global variable as local to the function, or
      063806
      use another name for the regular expression variable (which is not
      063806
      very convenient in order to keep the amount of names to remember low),
      063806
      you may experiment undesired concantenation issues that make your
      063806
      regular expression to be something different from that you expect them
      063806
      to be, specially if the function where you are doing the variable
      063806
      redefinition is called several times during the same script execution.
      063806

      063806

      As result, the cli_getFilesList re-defines the value of

      063806
      FILES variable with the list of files the find command
      063806
      returned. As example, consider the following construction:
      063806

      063806
      function prefix_doSomething {
      063806
      063806
          # Initialize the list of files to process.
      063806
          local FILES=''
      063806
      063806
          # Initialize location.
      063806
          local LOCATION=/home/centos/artwork/trunk/Identity/Themes/Models/Default
      063806
      063806
          # Re-define regular expression to match scalable vector graphic
      063806
          # files only. Note how we use the global value of REGEX to build a
      063806
          # new local REGEX value here.
      063806
          local REGEX="${REGEX}.*\.(svgz|svg)"
      063806
      063806

      format LL_CC and outputs the language related name as in ISO639. If
      063806

      063806

      Inside <tt>`centos-art.sh'</tt> script, specific functionalities rely both

      063806
      in cli_getRepoName and repository file system organization to
      063806
      achieve their goals.  Consider cli_getRepoName function as
      063806
      central place to manage file name convenctions for other functions
      063806
      inside <tt>`centos-art.sh'</tt> script.
      063806

      Important

      Important

      cli_getRepoName function doesn't verify file

      063806
      or directory existence, for that purpose use cli_checkFiles
      063806
      function instead.
      063806

      063806
      063806

      The NAME variable contains the file name or directory name you

      063806
      want to sanitate.
      063806

      063806

      The TYPE variable specifies what type of sanitation you want to

      063806
      perform on NAME. The TYPE can be one of the following
      063806
      values:
      063806

      063806
      063806
      <samp>`d'</samp>
      063806
      <samp>`directory'</samp>
      063806

      Sanitate directory NAMEs.

      063806

      <samp>`f'</samp>
      063806
      <samp>`regular-file'</samp>

      063806

      063806
      063806
      063806

      Use cli_getRepoName function to sanitate file names and

      063806
      directory names before their utilization. 
      063806

      063806

      Use cli_getRepoName when you need to change file name

      063806
      convenctions inside <tt>`centos-art.sh'</tt> script. 
      063806

      063806

      When we change file name convenctions inside cli_getRepoName

      063806
      what we are really changing is the way functions interpret repository
      063806
      file system organization. Notice that when we change a file name
      063806
      (e.g., a function name), it is necessary to update all files where
      063806
      such file name is placed on. This may require a massive substitution
      063806
      inside the repository, each time we change name convenctions in the
      063806
      repository (-- Removed(pxref:trunk Scripts Bash Functions Path) --, for more
      063806
      information).

      063806
      <u>Function:</u> cli_getRepoStatus [LOCATION]
      063806
      063806
      063806

      Request repository status.

      063806

      063806

      This function requests the status of a LOCATION inside the

      063806
      working copy using the svn status command and returns the
      063806
      first character in the output line, just as described in svn
      063806
      help status. If LOCATION is not a regular file or a directory,
      063806
      inside the working copy, the <tt>`centos-art.sh'</tt> script prints a
      063806
      message and ends its execution.
      063806

      063806

      Use this function to perform verifications based a repository

      063806
      LOCATION status.

      <u>Function:</u> cli_getTemporalFile NAME
      063806
      063806
      063806

      Output absolute path to temporal file NAME.

      063806

      063806

      The cli_getTemporalFile function uses <tt>`/tmp'</tt> directory as

      063806
      source location to store temporal files, the <tt>`centos-art.sh'</tt>
      063806
      script name, and a random identification string to let you run more
      063806
      than one <tt>`centos-art.sh'</tt> script simultaneously on the same user
      063806
      session.  For example, due the following temporal file defintion:
      063806

      063806
      cli_getTemporalFile $FILE
      063806
      063806

      If FILE name is <tt>`instance.svg'</tt> and the unique random string

      063806
      is <samp>`f16f7b51-ac12-4b7f-9e66-72df847f12de'</samp>, the final temporal
      063806
      file, built from previous temporal file definition, would be:
      063806

      063806
      /tmp/centos-art.sh-f16f7b51-ac12-4b7f-9e66-72df847f12de-instance.svg
      063806
      063806

      When you use the cli_getTemporalFile function to create

      063806
      temporal files, be sure to remove temporal files created once you've
      063806
      ended up with them.  For example, consider the following construction:
      063806

      063806
      for FILE in $FILES;do
      063806
      063806
          # Initialize temporal instance of file.
      063806
          INSTANCE=$(cli_getTemporalFile $FILE)
      063806
      063806
          # Do something ... 
      063806
      063806
          # Remove temporal instance of file.
      063806
          if [[ -f $INSTANCE ]];then
      063806
              rm $INSTANCE
      063806
          fi
      063806
      063806
      done
      063806
      063806

      Use the cli_getTemporalFile function whenever you need to

      063806
      create temporal files inside <tt>`centos-art.sh'</tt> script.
      063806

      063806
      063806
      063806
      <u>Function:</u> cli_getThemeName
      063806
      063806
      063806

      Output theme name.

      063806

      063806

      In order for cli_getThemeName function to extract theme name

      063806
      correctly, the ACTIONVAL variable must contain a directory path
      063806
      under <tt>`trunk/Identity/Themes/Motifs/'</tt> directory structure.
      063806
      Otherwise, cli_getThemeName returns an empty string.  
      063806

      063806
      063806
      063806
      <u>Function:</u> cli_printMessage MESSAGE [FORMAT]
      063806
      063806
      063806

      Define standard output message definition supported by

      063806
      <tt>`centos-art.sh'</tt> script.
      063806

      063806

      When FORMAT is not specified, cli_printMessage outputs

      063806
      information just as it was passed in MESSAGE variable.
      063806
      Otherwise, FORMAT can take one of the following values:
      063806

      063806
      063806
      <samp>`AsHeadingLine'</samp>
      063806
