We currently use GitHub. In the context of #12526 it has been suggested to move to a different git forge and several people have expressed their support for such a change. The main reasons to move off of GitHub as I see it are: their push of LLM features without a way of…
- LLM policyClosed
As discussed in #12526, this is an issue requesting an LLM policy. I'm a bit surprised that an LLM policy request wasn't made since. The negatives have already been stated in that issues, so I won't repeat them here. I am creating this because I found a commit from someone using…

Currently, Fish shell autosuggestions are based on command history. While I love this, it would be beneficial to allow users to implement their own autosuggestion logic. This would open the door to powerful enhancements, such as AI-based completions that leverage historical…

EDIT for visibility: TL;DR: the new default behavior in fish 4.1 is effectively the following. Feel free to override by adding your desired binds to /.config/fish/config.fish --- Steps to reproduce: Install fish v4b1. I got mine from here Type in the terminal something like this…

fish, version 4.3.2 Soft-wrapping autocompletions break when fishrightprompt is not empty. Reproduction: 1. Define function fishrightprompt; echo "a"; end 2. Autocompletions wrap around to the same line, overwriting the prompt

puts all my abbreviations with --position=anywhere or --command=foo into tab completion. Tab completing file paths is unusable because it is filled up with abbreviations. Also, tab completion with a single file in the directory no longer populates the file name. In my dotfiles, I…

fish version 4.9 kitty macOS This started happening as soon as I upgraded to 4.9 . So the issue is definitely with this release. Doesn't happen in kitty+bash, or iTerm+fish . 1) switch to dvorak keyboard layout. 2) press the ; qwerty key , which in dvorak is s 3) s should be…
- Stop using terminfoClosed
As I've alluded to before, I think we should stop listening to the terminfo database entirely. This is because: we barely use it it is frequently wrong it is massively incomplete and shows no signs of improving it does not have versioning so old entries remain in use even on new…

fish 4.2.0 on Linux I use alt+backspace very heavily when cd'ing around to remove one level at a time from the path. This broke with the latest update. Now backward-kill-token removes the entire path. I can't (easily) tell when it broke exactly, because Fedora only ships a 4.0…

I can't understand the why adding the f/foo in the following example changes the way arguments are parsed.. am I missing something obvious or is it a bug? I'd expect the f/foo to have no effect at all on the parsisng: arg is still an unknown argument and --unknown-arguments…

Rust and Lua both have string literals with delimiters of varying length, which can represent any string without escaping, including strings that contain what look like closing delimiters, as long as the literal's actual delimiters are chosen to be longer. In Rust, r###"they look…

I would like to use the setcolor builtin to choose from the 8-bit color space (see here). I took a look through the existing code and I think this would only require a change in the color crate, with the addition of a new tryparse: The only thing I'm not sure about is what sigil…

In fish, it seems cd dir or cd -P dir does the equivalent of cd $PWD/dir without checking that $PWD still corresponds to a path to the current working directory. And fish doesn't have subshells ( and things like pushd/popd to try and restore the current working directory are…
