Oh-My-Zsh Sorin for Fish!

"Opinionated" (lazy) port of the Oh-My-Zsh "Sorin" theme for the Fish Shell.

What? Why? Isn't there already a Sorin theme for Fish?

Yes, in fact, there are two just in the main Fish repo alone (and probably an untold amount in the wild!)

However, I found the one in fish_config to be lacking some features (Git), and the second one too complex to understand what was happending (especially when compairing the source for the oh-my-zsh original), so I started hacking.

Installation

Variable support

snorin_chevrons

by default, this prompt will give you one green ❯ symbol (this is how the Oh-My-Zsh Sorin does it)
However, the "Sorin" themes for Fish usually have three: a red ❯, a yellow ❯, and a green ❯ (something like ❯❯❯) .

I decided to let the user chose.
You can have as many ❯ 's as you want with this theme by setting

set snorin_chevrons color1 color2 color3 .. color n

For example, I like the red, yellow, green, so I have mine set as

set -U snorin_chevrons red yellow green

Random Fun

I thought it might be fun to have the ability to have random colors generated for your prompts, so I wrote a little function that uses either jot or shuf (make sure you have at least one of these installed²) to help make some random colors for your prompts. It works like this

snorin_random_chevrons N

(where N is the number of chevrons you want)

For Instance

If you want each new term session/tab to have a different prompt, then make sure that snorin_chevrons isn't set with the -U flag (easist way to do this is do set -e snorin_chevrons and that will unset it, and allow the random script to take over)

Then in your fish_config you can do something like

if type snorin_random_chevrons > /dev/null 2>&1
    snorin_random_chevrons 3 > /dev/null 2>&1
end

(type X will list the definition or location of a function/program if it exists. > /dev/null 2>&1 shoves the output to oblivion, but type will still return with a status that if can check against. This confused me the first few times I saw it.)

That should give each new session/tab a different set of colors (maybe. I only defined 10 colors so duplicates will happen)

This is just a "for instance". There's hundreds of triggering events you could use to have a prompt change colors or number of ❯. Use your imagination!

Footnotes
1 Based on https://git-scm.com/docs/git-status there's are quite a few cases I didn't code for because I don't come across them very often. I figured ◊ looked innocent enough. If you come across this a lot, please help me out and file an issue with details or make a PR yourself 🙇‍♂️ ↩

2 Interestingly enough, shuf doesn't do duplicates, whereas jot does. I don't consider this an issue, but this might drive some people crazy ↩
