fish | Stuff I'm Up To

I’ve been using the excellent zsh and antigen for a while, but one thing really annoyed me. The autocomplete often showed duplicate characters or mangled the line somehow. I thought I’d have a look at fish shell.

In zsh I like my simple ay theme. Shows me where I am and what my git status is, turns out I can use the same/equivalent theme in fish. Even more fun it has an extension called “Oh My Fish” paying homage, or tongue in cheek, to “Oh My Zsh”. Install fish and Oh My Fish.

pamac install fish
curl https://raw.githubusercontent.com/oh-my-fish/oh-my-fish/master/bin/install | fish

Get Oh My Fish to install the ays theme.

omf install ays

What am I missing? Docker aliases - I make big use of dcupd, dclf, etc. How do I get my aliases into fish? There doesn’t appear to be a docker/docker compose plugin like there is in Oh My Zsh, but aliases can be added to your fish config in ~/.config/fish/fish.config just like your ~/.zshrc. But I then discovered abbr. A nice feature of fish that acts like aliases, but expands them out as you type, eg. dclf becomes the full docker compose logs -f as soon as you hit the spacebar.

This is my fish.config, a few docker aliases, with exa, bat and nvim.

if status is-interactive
    # Commands to run in interactive sessions can go here
    abbr -a -- dcps 'docker compose ps'
    abbr -a -- dclf 'docker compose logs -f'
    abbr -a -- dcup 'docker compose up'
    abbr -a -- dcupd 'docker compose up -d'
    abbr -a -- dcdn 'docker compose down'
    abbr -a -- dcl 'docker compose logs'
    abbr -a -- ls 'exa'
    abbr -a -- cat 'bat -p'
    abbr -a -- vi nvim
    abbr -a -- vim nvim
end
