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.
