nix-env.fish

Sets up the Nix environment for a non-NixOS Fish shell.

Beyond just setting up $PATH and the various $NIX_* environment variables, this also sets up $fish_function_path and $fish_complete_path to include any Nix-installed Fish functions/completions, and sources any Nix-installed Fish conf.d.

Install

Any Fish package manager should be able to install this.

Fisher

fisher install lilyball/nix-env.fish

Manual install

You can install this manually by copying or symlinking the conf.d/nix-env.fish file into your ~/.config/fish/conf.d/ folder.
