############### ↓ Nix hook for sourcing /etc/fish/config.fish ↓ ###############
|
|
# #
|
|
# Origin:
|
|
# This fish package was called with the attribute
|
|
# "useOperatingSystemEtc = true;".
|
|
#
|
|
# Purpose:
|
|
# Fish ordinarily sources /etc/fish/config.fish as
|
|
# $__fish_sysconfdir/config.fish,
|
|
# and $__fish_sysconfdir is defined at compile-time, baked into the C++
|
|
# component of fish. By default, it is set to "/etc/fish". When building
|
|
# through Nix, $__fish_sysconfdir gets set to $out/etc/fish. Here we may
|
|
# have included a custom $out/etc/config.fish in the fish package,
|
|
# as specified, but according to the value of useOperatingSystemEtc, we
|
|
# may want to further source the real "/etc/fish/config.fish" file.
|
|
#
|
|
# When this option is enabled, this segment should appear the very end of
|
|
# "$out/etc/config.fish". This is to emulate the behavior of fish itself
|
|
# with respect to /etc/fish/config.fish and ~/.config/fish/config.fish:
|
|
# source both, but source the more global configuration files earlier
|
|
# than the more local ones, so that more local configurations inherit
|
|
# from but override the more global locations.
|
|
|
|
