Window switcher for sway ('rofi -show window' clone)

sway-window-menu

#!/usr/bin/env bash

set -euo pipefail

tree=$(swaymsg -t get_tree)
readarray -t win_ids <<< "$(jq -r '.. | objects | select(has("app_id")) | .id' <<< "$tree")"
readarray -t win_names <<< "$(jq -r '.. | objects | select(has("app_id")) | .name' <<< "$tree")"
readarray -t win_types <<< "$(jq -r '.. | objects | select(has("app_id")) | .app_id // .window_properties.class' <<< "$tree")"

switch () {
    local k
    read -r k
    swaymsg "[con_id=${win_ids[$k]}] focus"
}

for k in $(seq 0 $((${#win_ids[@]} - 1))); do
    echo -e "<span weight=\"bold\">${win_types[$k]}</span> - ${win_names[$k]}"
done | rofi -dmenu -markup-rows -i -p window -format i | switch

... and i rewrote this so it works with fuzzel, which involved (unfortunately) removing the fancy pango markup, but it should work with anything that supports dmenu now (as long as it also supports rofi's icon system):

Sometimes app_ids are not enough in my experience, and sometimes app_ids don't translate to icons.

I updated @bellecp's script to accommodate this:

row=$(swaymsg -t get_tree | jq -r '
    ..
    | objects
    | select(.type == "workspace") as $ws
    | ..
    | objects
    | select(has("app_id"))
    | (if .focused == true then "*" else " " end) as $asterisk
    | (
        if .window_properties.class == "Spotify" then "spotify-client" 
        elif .window_properties.class == "LM Studio" then "lm-studio" 
        else .app_id // .window_properties.class // .name 
      end ) as $icon_name
    | "[\($ws.name)] \($asterisk) <span weight=\"bold\">\(.app_id // .window_properties.class)</span>  - \(.name) <!-- \(.id) -->\u0000icon\u001f\($icon_name)"
    ' |
	sed 's/&/&amp;/g' |
	rofi -dmenu -show-icons -markup-rows -p "window")

if [ ! -z "$row" ]; then
	winid=$(echo "$row" | sed 's/.*<!-- \([0-9]*\) -->.*/\1/')
	swaymsg "[con_id=$winid] focus"
fi

There probably is a better way at detecting icons (rofi -show window) does a somewhat better job. I guess you might be able to map the app names to icons thorugh their .desktop files.
