# We are prohibited from bundling fonts, and we are prohibited from shipping
# fonts in web font formats; see
# https://docs.fedoraproject.org/en-US/packaging-guidelines/FontsPolicy/#_web_fonts.
#
# Since upstream uses *only* web fonts, we need a patch. We haven’t offered it
# upstream since upstream has no reason NOT to use web fonts.
#
# This patch removes all references to WOFF/WOFF2 font files (which we still
# must remove in %%prep) and ensures the CSS correctly references corresponding
# local system fonts.

# python3-toml is deprecated
# https://fedoraproject.org/wiki/Changes/DeprecatePythonToml
# Backport upstream changes to migrate to tomllib and fallback to tomli and toml
# We technically only need the following two:
#   https://gitlab.gnome.org/GNOME/gi-docgen/-/merge_requests/168
#   https://gitlab.gnome.org/GNOME/gi-docgen/-/merge_requests/174 (fixup of 168)
# But the following two were deemed necessary upstream as well:
#   https://gitlab.gnome.org/GNOME/gi-docgen/-/merge_requests/172
#   https://gitlab.gnome.org/GNOME/gi-docgen/-/merge_requests/173
# Patches trivially joined to one file with cat.

# Trivial fork of https://github.com/jhawthorn/fzy.js (looks like it was

# It’s not clear what version was used for the fork.

%description
GI-DocGen is a document generator for GObject-based libraries. GObject is the
base type system of the GNOME project. GI-Docgen reuses the introspection data
generated by GObject-based libraries to generate the API reference of these
libraries, as well as other ancillary documentation.

GI-DocGen is not a general purpose documentation tool for C libraries.

While GI-DocGen can be used to generate API references for most GObject/C
libraries that expose introspection data, its main goal is to generate the
reference for GTK and its immediate dependencies. Any and all attempts at
making this tool more generic, or to cover more use cases, will be weighted
heavily against its primary goal.

GI-DocGen is still in development. The recommended use of GI-DocGen is to add
it as a sub-project to your Meson build system, and vendor it when releasing
dist archives.

You should not depend on a system-wide installation until GI-DocGen is declared
stable.

%description fonts
Because web fonts from upstream are not bundled in the gi-docgen package,
documentation packages generated with gi-docgen must depend on this metapackage
to ensure the proper system fonts are present.
