Guillaume Girol 33afbf39f6 treewide: switch to nativeCheckInputs
checkInputs used to be added to nativeBuildInputs. Now we have
nativeCheckInputs to do that instead. Doing this treewide change allows
to keep hashes identical to before the introduction of
nativeCheckInputs.

# An optional string containing Fish code that initializes the environment.
# This is run at the very beginning of initialization. If it sets $NIX_PROFILES
# then Fish will use that to configure its function, completion, and conf.d paths.
# For example:
# fishEnvPreInit = "source /etc/fish/my-env-preinit.fish";
# It can also be a function that takes one argument, which is a function that
# takes a path to a bash file and converts it to fish. For example:
# fishEnvPreInit = source: source "${nix}/etc/profile.d/nix-daemon.sh";

############### 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.
#
# Special care needs to be taken, when fish is called from an FHS user env
# or similar setup, because this configuration file will then be relocated
# to /etc/fish/config.fish, so we test for this case to avoid nontermination.
