My fish shell AI setup on macOS

I installed the fish shell and fisher plugin manager through the malt package manager client (you can also use Homebrew, and I'm showing the paths resulting from a Homebrew install). I also just started using the Starship prompt.

The instructions also work on Linux, but you'd need to install a current version of fish through the corresponding PPA:

sudo add-apt-repository ppa:fish-shell/release-4

Once installed, you can choose fish as your default shell:

$ chsh -s /opt/homebrew/bin/fish # set as systemwide shell

Then I installed these plugins using fisher. You can read the documentation in their Github repos:

❯ fisher list
jorgebucaran/fisher
realiserad/fish-ai
franciscolourenco/done
jethrokuan/z
patrickf1/fzf.fish
reitzig/sdkman-for-fish@v2.1.0

You need to install the related tools, such as fzf, sdkman, etc. separately.

Here are my settings for tide to look like omz and sdkman to work as intended.

❯ cat ~/.config/fish/config.fish
if status is-interactive
    # Commands to run in interactive sessions can go here

    starship init fish | source

    eval "$(mt shellenv)"

    fish_add_path $HOME/.local/bin
    fish_add_path $HOME/.cargo/bin

    set -Ux SDKMAN_DIR $HOME/.sdkman

end

Groq (not to be confused with Grok) can provide a free API key for fish AI integration, where you can type a shell comment and a hotkey, and fish expands it to the actual shell command.

❯ cat ~/.config/fish-ai.ini
[fish-ai]
configuration = groq

[groq]
provider = groq
model = openai/gpt-oss-20b
api_key = ...

I had to add these completions to get git tag TAB to work.

❯ cat ~/.config/fish/completions/git.fish
complete -c git -n '__fish_seen_subcommand_from tag' -f -a '(command git tag 2>/dev/null)'
