############### 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.
if test -f /etc/fish/config.fish
source /etc/fish/config.fish

# data comes last. Files are loaded/sourced in encounter order, duplicate
# basenames get skipped, so we assure this by prepending Nix profile paths
# (ordered in reverse of the $NIX_PROFILE variable)
#
# Note that at this point in evaluation, there is nothing whatsoever on the
# fish_function_path. That means we don't have most fish builtins, e.g., `eval`.
# additional profiles are expected in order of precedence, which means the reverse of the
