Interested in using kitty in the same way fzf-tmux works

[megalithic]

Hi!

I'm looking at ways to use kitty, as a replacement, in many ways, to tmux. One thing that tmux allows, which is so helpful (and fzf-tmux makes possible) is.. fzf in a quick pane. Kitty has something similar, in way of different types of targets for kitty, one being an overlay, which is a "quick" full size popup.

So, my question is, has anyone gotten fzf-tmux-like functionality via kitty and it's overlay launch type?

This works on my Mac. It works both in a pipeline (>ls | fzf-kitty) and not (>fzf-kitty). It involves two scripts.

The first is _fzf-kitty-to, which is for the fzf-kitty script to call:

#!/bin/bash

# https://github.com/junegunn/fzf/issues/2481#issuecomment-839591602
tail_app="tail"
if [[ "$(uname)" == "Darwin" ]]; then
    tail_app=gtail
fi

if [[ -f "$INFILE" ]]; then
    $tail_app -f "$INFILE" | fzf "$@" >"$OUTPIPE"
else
    fzf "$@" >"$OUTPIPE"
fi

And the actual fzf-kitty script:

#!/bin/sh

outpipe=$(mktemp -u)
mkfifo -m 600 "$outpipe"

if [ ! -t 0 ]; then
    infile=$(mktemp /tmp/fzf-kitty.XXXXXX)
    while read -r line; do
        echo "$line" >>"$infile"
    done
fi

kitty @launch --cwd "$PWD" --env "PATH=$PATH" --env "INFILE=$infile" --env "OUTPIPE=$outpipe" _fzf-kitty-to "$@" >/dev/null

read -r line <"$outpipe"

if [ ! -t 0 ]; then
    rm "$infile"
fi
rm "$outpipe"
echo "$line"
