Tab completion support

[autolyticus]

Are there any plans for enabling the fuzzy search and completion from getting the output from "complete -C".
Most commands have pretty good completion these days and it would save a lot of time to fill in for example the output of docker container stop, or of tmux sessions.

This used to technically be an implemented feature on jethrokuan/fzf but had quite a few bugs with the implementation, especially with fish-shell itself not returning the quoted strings as output of "complete -C": fish-shell/fish-shell#3469

this would definitely be nice and a feature I miss... there's a nice implementation for zsh using https://github.com/romkatv/zsh4humans

its tab completion is really nice especially when cd-ing

something like this? https://github.com/DevAtDawn/fish-fzf-tab

function clia
    read -l line; commandline -a $line
    # commandline -a 
end

bind -M insert \et 'fuzzy_complete'

function fuzzy_complete
    complete -C | sort -u | fzf --height 40% --multi --reverse -q (commandline -t) | cut --output-delimiter ' ' -f1 | sed 's/-//g' | clia
    commandline -f end-of-line 
end

@DevAtDawn Thanks for the script!
I'm not sure why, but your script doesn't work on my setup directly (macOS Ventura/fish3.6).
Using your script as a blueprint, I made mine too!

# $XDG_CONFIG/fish/config.fish 
...
# Replace fish's default tab pager with fuzzy_complete powered by fzf
bind \t fuzzy_complete
...

# $XDG_CONFIG/fish/functions/fuzzy_complete.fish
function fuzzy_complete
    set -f selected (complete -C | fzf -q (commandline -t) | cut -f1)

    commandline --function repaint
    commandline --current-token --replace -- (string escape -- $selected)
end

I'm completely a newbie in fish scripting, feel free if y'all want to tweak it!

Here's an example:

Check this out everyone! #293
Could people upvote this so it's more prominent?

Oh that is the only open pull request :P
Thanks for the heads-up, I didn't notice! (I upvoted :) )

After giving a serious try to implement this, I decide to not ever do this. See my final comment in .
