nnn-kdialog

#!/bin/sh

## Instructions
# - Place this file as /usr/local/bin/kdialog
# - Set XDG_CURRENT_DESKTOP=KDE
# - Copy quitd to .config/nnn/plugins, make it executable

# To pick a directory in nnn, press Space or Ctrl-J.
# Or simply type ;l to apply the quitd plugin to select pwd

## Debugging
# args="$@"
# notify-send "kdialog $args"
# echo "kdialog $args" >> $HOME/kdialog-log

# dl_dir="$HOME/dl"

export NNN_PLUG='l:quitd'

# $1 is the window title
# $2 is the default directory
getopenfilename() {
    ! [ -d "$2" ] && dir="$HOME" || dir="$2"
    $TERMINAL -t "$1" -e nnn -A -p /tmp/fileselect "$dir"
    path=$(tail -n 1 /tmp/fileselect)
    [ -f "$path" ] && [ -f /tmp/fileselect ] && echo $path
    rm /tmp/fileselect
}

getexistingdirectory() {
    $TERMINAL -t "$1" -e nnn -A -p /tmp/fileselect "$2"
    path=$(tail -n 1 /tmp/fileselect)
    [ -d "$path" ] && [ -f /tmp/fileselect ] && echo $path
    rm /tmp/fileselect
}

# $2 is the default filename
getsavefilename() {
    [ -n dl_dir ] && dir="$(getexistingdirectory "$1")" || dir="$dl_dir"

    fname=$(echo "$2" | dmenu)
    # If user did not choose default, add extension
    ! [ "$fname" == "$2" ] && [ -n "$fname" ] && [ -n "$2" ] && fname="$fname"."${2#*.}"

    # Replace spaces with underscores
    fname=$(echo "$fname" | tr " " "_")

    [ -n "$dir" ] && [ -n "$fname" ] && echo "$dir"/"$fname"
}

version() {
    # impersonate the latest version
    echo "kdialog 21.12.1"
}

## Parse options
for (( i=1; i<=$#; i++ ));
do
    case ${!i} in
    --getopenfilename | --getexistingdirectory )
        # get rid of the leading dashes
        fun=${!i##--}
        (( i++ ))
        secondary="${!i}"
        ;;
    --version )
        fun=${!i##--}
        ;;
    --getsavefilename )
        fun=${!i##--}
        (( i++ ))
        save_path="${!i}"
        secondary="${save_path##/*/}"
        ;;
    --title )
        (( i++ ))
        title=${!i}
        ;;
    esac
done 2> /dev/null;

title=${title:-nnn-kdialog}

## Epic functional programming trick
if ! [ -z "$fun" ]; then
    echo "$($fun "$title" "$secondary")" # | tee -a $HOME/kdialog-log
