I’ve just moved from zsh to fish today and guess what, there were some bumps on the road.

First of all, I’ve been reading some blog posts before migrating which were all rainbows and unicorns on the idea that fish installs quite smooth and without any issues whatsoever, but those were written 6mo. or even +1 years ago and as you already know, a lot can change in the Tech/IT/Software domain in that amount of time and when it does it breaks some shits.

This is only valid for Apple Silicon Macs, the Intel-based Macs will just install the package in its ordinary place ( /usr/local/bin/fish ). The installation was ran on M1 Mac with MacOS Monterey 12.5.

Initial install #

`chsh: /etc/shells: non-standard shell` #

Like ordinary people, I started with

brew install fish

echo "/usr/local/bin/fish" | sudo tee -a /etc/shells

chsh -s /usr/local/bin/fish

But guess what, you get

chsh: /etc/shells: non-standard shell

Wanna know why?

Because homebrew doesn’t install the binary at /usr/local/bin/fish but rather /opt/homebrew/bin/fish, if you run this again the right way, it’ll work.

brew install fish
echo "/opt/homebrew/bin/fish" | sudo tee -a /etc/shells
chsh -s /opt/homebrew/bin/fish

One problem solved. Now restart terminal and let’s move to the next one.

`fish: Unknown command: fish` #

Since it was installed via homebrew, those binaries are on a different path therefore we need to append it to the ${PATH}.

# ~/.config/fish/config.fish
if status is-interactive
    # Commands to run in interactive sessions can go here
    export PATH="$PATH:/opt/homebrew/bin:/opt/homebrew/opt/openjdk/bin"
end

Plug-in managers #

Now we are able to continue installing omf, thanks Travis for your blog post.

curl -L https://get.oh-my.fish | fish

Additionally, there’s fisher which I’m not installing it because I don’t want to bloat my fish 😆

curl -sL https://git.io/fisher | source && fisher install jorgebucaran/fisher

Fine-tuning #

After finishing with the initial installation, I need some basic tooling like fzf. Guess what, the initial fzf is not going to do, therefore we need the fzf.fish from https://github.com/PatrickF1/fzf.fish

I’ve followed Travis’s suggestions to pull it through fisher, but Patrick (the maintainer of fzf.fish) said you don’t need fisher for that, but I’m lazy meh 🤫

But when you ⌘+R it just farts

⋊> ~/Projects fish: Unknown command: fzf
~/.config/fish/functions/_fzf_wrapper.fish (line 19):
    fzf $argv
    ^
in function '_fzf_wrapper' with arguments '--read0 --tiebreak=index --query= --preview=echo\ --\ \{4..\}\ \|\ fish_indent\ --ansi --preview-window=bottom:3:wrap'

in command substitution
	called on line 8 of file ~/.config/fish/functions/_fzf_search_history.fish
in function '_fzf_search_history'

Therefore, time for more 🪓

Then we notice in the readme of fzf.fish

Off we go to do the prereqs

brew install fd fzf bat
... 5h later **spongebob theme** ...
==> fd
fish completions have been installed to:
  /opt/homebrew/share/fish/vendor_completions.d
==> fzf
To install useful keybindings and fuzzy completion:
  /opt/homebrew/opt/fzf/install

To use fzf in Vim, add the following line to your .vimrc:
  set rtp+=/opt/homebrew/opt/fzf
==> bat
fish completions have been installed to:
  /opt/homebrew/share/fish/vendor_completions.d

NOW finally we’re ready to go: ⌘+R and evrika!

Fonts and shit #

Fuck’em. I don’t need that crap, defaults are just fine. As long as I can clearly read whatever’s in my term I don’t need no bells and whistles.

Bonus tip: bang bang !! and bang dollar !$ tokens #

Drop these functions in your ~/.config/fish/config.fish or anywhere fish 🐟 could pick them up.

function bind_bang
    switch (commandline -t)[-1]
        case "!"
            commandline -t $history[1]; commandline -f repaint
        case "*"
            commandline -i !
    end
end

function bind_dollar
    switch (commandline -t)[-1]
        case "!"
            commandline -t ""
            commandline -f history-token-search-backward
        case "*"
            commandline -i '$'
    end
end

function fish_user_key_bindings
    bind ! bind_bang
    bind '$' bind_dollar
end

And then you can sudo !! or whatever.

Kudos:

Moving `zsh` history to `fish` #

I’ve done some ddg.co searches but last that I found were some dodgy python scripts which I currently don’t have the time and patience to go through and understand before actually running random shit from the internet. Never. Do. That. Ever.

If it was a Rust or Go binary then I’d trust it 😺

What did I gain from this? #

I’m a prowd vscodium user and I have to say with fish I finally got rid of that shitty pop-up error each time I was closing the shell via ⌃+D. This was fucking anoying because when I was to git commit something, write the message and exit via :x from vim, you’d normally have to ESC to drop to Normal mode in order to go into command mode.
It’s fuckin’ fast mate!
Typing suggestions - well thank you! It has really good support for these, not only that but it’s also showing typing errors in red
