Feature parity with OG ueberzug

[jstkdng]

This is an issue to keep track of features that are availabe on ueberzug but aren't in ueberzugpp. If there's something else missing feel free to comment.

• X11 output
• Display multiple images at the same time
• Json parser
• Bash parser
• Image scaler crop
• Image scaler distort
• Image scaler fit_contain
• Image scaler contain
• Image scaler forced_cover
• Image scaler cover

Aditional comments

• Only project that still uses the bash parsers that I could find is ucollage, looks pretty dead though
• Partial implementation of the scalers fit_contain and forced_cover
• Implementing the other scalers in a non-hacky way could require a large refactor

https://github.com/munguua/ncmpcpp-ueberzug this project use bash parser and not json, but i ugly fixed in my fork

not only is the project dead, it has issues disabled. I think it'd be better for you to improve your fork tbh.

i forgot this actually doesn't use uz++

bruh

[justchokingaround]

this was the uz++ implemention i think. tho iirc it was a bit slow:

#!/bin/sh
set -e

max_width=45
max_height=45
preview_method="sixel"

cleanup() {
    ueberzugpp cmd -s "$UB_SOCKET" -a exit
}
trap cleanup HUP INT QUIT TERM PWR EXIT

UB_PID_FILE="/tmp/.$(uuidgen)"
ueberzugpp layer --no-cache -o "$preview_method" --no-stdin --silent --use-escape-codes --pid-file "$UB_PID_FILE"
UB_PID="$(cat "$UB_PID_FILE")"
export UB_SOCKET=/tmp/ueberzugpp-"$UB_PID".socket
while :; do
    title=$(playerctl metadata xesam:url 2>/dev/null | sed -nE "s@.*/(.*)\.(mp3|flac|opus|mkv|m4a)@\1@p")
    if [ -n "$title" ]; then
        path="$HOME/.cache/ncmpcpp/images/""$title.jpg"
        if [ "$old_path" != "$path" ]; then
            tput clear
            ueberzugpp cmd -s "$UB_SOCKET" -a add -i PREVIEW -x 0 -y 0 --max-width "$max_width" --max-height "$max_width" -f "$path"
        fi
        old_path="$path"
        sleep 2
    fi
done
