# Runtime-only deps are probably incomplete and approximate.
# Introspection deps generated from inspection of the output of:
#  for i in `rg -INUo 'const(?s).*imports.gi' |cut -d= -f1 |cut -c7- |sort -u`; do echo $i ;done |cut -d, -f1 |sort -u
# or
#  rg -INUo 'const(?s).*imports.gi' |cut -d= -f1 |cut -c7- | sed -e 's:[{}]::g' | awk '{$1=$1; print}' | awk -F',' '{$1=$1;print}' | tr ' ' '\n' | sort -u | sed -e 's/://g'
# These will give a lot of unnecessary things due to greedy matching (TODO), and `(?s).*?` doesn't seem to work as desired.
# Compare with `grep -rhI 'imports.gi.versions' |sort -u` for any SLOT requirements
# Each block:
# 1. Introspection stuff needed via imports.gi (those that build time check may be listed above already)
# 2. gnome-session needed for shutdown/reboot/inhibitors/etc
# 3. Control shell settings
# 4. xdg-utils needed for xdg-open, used by extension tool
# 5. adwaita-icon-theme needed for various icons & arrows (3.26 for new video-joined-displays-symbolic and co icons; review for 3.28+)
# 6. mobile-broadband-provider-info, timezone-data for shell-mobile-providers.c  # TODO: Review
# 7. IBus is needed for nls integration
# 8. Cantarell font used in gnome-shell global CSS (if removing this for some reason, make sure it's pulled in somehow for non-meta users still too)
# 9. xdg-desktop-portal-gtk for various integration, e.g. #764632
# 10. TODO: semi-optional webkit-gtk[introspection] for captive portal helper
