# 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.

%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).
|
||
|
||
This copy of the library is compiled with LLHTTP_STRICT_MODE set to 0
|
||
(disabled), which is the default.
