# When bumping, pay attention to all the included plugins/*/meson.build (and other) build files and the requirements within.
# `grep -rI dependency * --include='meson.build'` can give a good initial idea for external deps and their double checking.
# The listed RDEPEND order should roughly match that output as well, with toplevel one first then sorted by file path.
# Most plugins have no extra requirements and default to enabled; we need to handle the ones with extra requirements. Many of
# them have optional runtime dependencies, for which we try to at least notify the user via DOC_CONTENTS (but not all small
# things); `grep -rI -e 'command-pattern.*=' -e 'push_arg'` can give a (spammy) idea, plus python imports in try/except.

# Editorconfig needs old pcre, with vte migrating away, might want it optional or ported to pcre2?
# An introspection USE flag of a dep is required if any introspection based language plugin wants to use it (grep for gi.repository). Last full check at 3.28.4

# TODO: Handle llvm slots via llvm.eclass; see plugins/clang/meson.build

DOC_CONTENTS='gnome-builder can use various other dependencies on runtime to provide
extra capabilities beyond these expressed via USE flags. Some of these
that are currently available with packages include:

* dev-util/ctags with exuberant-ctags selected via "eselect ctags" for
  C, C++, Python, JavaScript, CSS, HTML and Ruby autocompletion, semantic
  highlighting and symbol resolving support.
* dev-python/python-lsp-server for more accurate Python
  autocompletion support.
* dev-util/valgrind for integration with valgrind.
* dev-util/meson for integration with the Meson build system.
* virtual/rust for integration with the Rust Cargo build system.
* dev-util/cmake for integration with the CMake build system.
* net-libs/nodejs[npm] for integration with the NPM package system.

# FIXME: Package codespell and mention here
# FIXME: Package gnome-code-assistance and mention here, or maybe USE flag and default enable because it's rather important
# eslint for additional diagnostics in JavaScript files (what package has this? At least something via NPM..)
# jhbuild support
# rust support via rust-analyzer; Go via go-langserver
# autotools stuff for autotools plugin; gtkmm/autoconf-archive for C++ template
# gjs/gettext/mono/PHPize stuff, but most of these are probably installed for other reasons anyways, when needed inside IDE
# stylelint for stylesheet (CSS and co) linting
# gvls for vala language-server integration
