How to get exiting into current directory and picture preview work with same command?

[thepenguinthatwants]

I managed to get picture preview to work using the following script.

#!/usr/bin/env bash

if [ -n "$DISPLAY" ] && command -v ueberzug > /dev/null; then
    export joshuto_wrap_id="$$"
    export joshuto_wrap_tmp="$(mktemp -d -t joshuto-wrap-$joshuto_wrap_id-XXXXXX)"
    export joshuto_wrap_ueber_fifo="$joshuto_wrap_tmp/fifo"
    export joshuto_wrap_pid_file="$joshuto_wrap_tmp/pid"
    export joshuto_wrap_preview_meta="$joshuto_wrap_tmp/preview-meta"
    export joshuto_wrap_ueber_identifier="preview"

    function start_ueberzug {
        mkfifo "${joshuto_wrap_ueber_fifo}"
        tail --follow "$joshuto_wrap_ueber_fifo" | ueberzug layer  --parser bash &
        echo "$!" > "$joshuto_wrap_pid_file"
        mkdir -p "$joshuto_wrap_preview_meta"
    }

    function stop_ueberzug {
        ueberzug_pid=`cat "$joshuto_wrap_pid_file"`
        kill "$ueberzug_pid"
        rm -rf "$joshuto_wrap_tmp"
    }

    function show_image {
        >"${joshuto_wrap_ueber_fifo}" declare -A -p cmd=( \
                [action]=add [identifier]="${joshuto_wrap_ueber_identifier}" \
                [x]="${2}" [y]="${3}" \
                [width]="${4}" [height]="${5}" \
                [path]="${1}")
    }

    function remove_image {
        >"${joshuto_wrap_ueber_fifo}" declare -A -p cmd=( \
            [action]=remove [identifier]="${joshuto_wrap_ueber_identifier}")
    }

    function get_preview_meta_file {
        echo "$joshuto_wrap_preview_meta/$(echo "$1" | md5sum | sed 's/ //g')"
    }

    export -f get_preview_meta_file
    export -f show_image
    export -f remove_image

    trap stop_ueberzug EXIT QUIT INT TERM
    start_ueberzug
    echo "ueberzug started"
fi

joshuto "$@"
exit $?

So I just call it by joshuto_pic and I can get the picture preview by ueberzug.

To get exiting into current directory I got it work by adding this to my .bashrc.

function joshuto() {
	ID="$$"
	mkdir -p /tmp/$USER
	OUTPUT_FILE="/tmp/$USER/joshuto-cwd-$ID"
	env joshuto --output-file "$OUTPUT_FILE" $@
	exit_code=$?

	case "$exit_code" in
		# regular exit
		0)
			;;
		# output contains current directory
		101)
			JOSHUTO_CWD=$(cat "$OUTPUT_FILE")
			cd "$JOSHUTO_CWD"
			;;
		# output selected files
		102)
			;;
		*)
			echo "Exit code: $exit_code"
			;;
	esac
}

The problem is I haven't gotten both to work with same command. I tried to make script run by joshuto command but it just makes starting joshuto loop. Tried to edit the script, but didn't get it to behave.

Any clue how to make both of this to work with same command?
