# This package is rather exotic. The compiled library is a typical shared
# library with a C API. However, it has only a tiny bit of C source code. Most
# of the library is written in TypeScript, which is transpiled to C, via LLVM
# IR, using llparse (https://github.com/nodejs/llparse)—all of which happens
# within the NodeJS ecosystem.
#
# The package therefore “builds like” a NodeJS package, and to the extent they
# are relevant we apply the NodeJS packaging guidelines. However, the result of
# the build “installs like” a traditional C library package and has no NodeJS
# dependencies, including bundled ones.
#
# Furthermore, the package is registered with npm as “llhttp”, but current
# releases are not published there, so we use the GitHub archive as the
# canonical source and use a custom bundler script based on
# nodejs-packaging-bundler to fetch NodeJS build dependencies.
#
# Overall, we cherry-pick from the standard and NodeJS packaging guidelines as
# each seems to best apply, understanding that this package does not fit well
# into any of the usual patterns or templates.
#
# Note that there is now a “release” tarball, e.g.
# https://github.com/nodejs/llhttp/archive/refs/tags/release/v%%{version}tar.gz,
# that allows this package to be built without the NodeJS/TypeScript machinery.
# However, the release archive lacks the original TypeScript source code for
# the generated C code, which we would need to include in the source RPM as an
# additional source even if we do not do the re-generation ourselves.

Summary:        Port of http_parser to llparse

# License of llhttp is (SPDX) MIT; nothing from the NodeJS dependency bundle is
# installed, so its contents do not contribute to the license of the binary

# Based closely on nodejs-packaging-bundler, except:
#
# - The GitHub source tarball specified in this spec file is used since the
#   current version is not typically published on npm
# - No production dependency bundle is generated, since none is needed—and
#   therefore, no bundled licenses text file is generated either

# While nothing in the dev bundle is installed, we still choose to audit for
# null licenses at build time and to keep manually-approved exceptions in a
# file.

%description
This project is a port of http_parser to TypeScript. llparse is used to
generate the output C source file, which could be compiled and linked with the
embedder's program (like Node.js).


%package devel
Summary:        Development files for llhttp

Requires:       llhttp%{?_isa} = %{?epoch:%{epoch}:}%{version}-%{release}

%description devel
The llhttp-devel package contains libraries and header files for
developing applications that use llhttp.
