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 end # # ############### ↑ Nix hook for sourcing /etc/fish/config.fish ↑ ############### ''; fishPreInitHooks = writeText "__fish_build_paths_suffix.fish" '' # source nixos environment # note that this is required: # 1.
