-# Description: Sample script to play files in apps by file type or mime
-#
-# Shell: POSIX compliant
-# Usage: nuke filepath
-#
-# Integration with nnn:
-#   1. Export the required config:
-#         export NNN_OPENER=/absolute/path/to/nuke
-#         # Otherwise, if nuke is in $PATH
-#         # export NNN_OPENER=nuke
-#   2. Run nnn with the program option to indicate a CLI opener
-#         nnn -c
-#         # The -c program option overrides option -e
-#   3. nuke can use nnn plugins (e.g. mocq is used for audio), $PATH is updated.
-#
-# Details:
-#   Inspired by ranger's scope.sh, modified for usage with nnn.
-#
-#   Guards against accidentally opening mime types like executables, shared libs etc.
-#
-#   Tries to play 'file' (1st argument) in the following order:
-#     1. by extension
-#     2. by mime (image, video, audio, pdf)
-#     3. by mime (other file types)
-#     4. by mime (prompt and run executables)
-#
-# Modification tips:
-#   1. Invokes CLI utilities by default. Set GUI to 1 to enable GUI apps.
-#   2. PAGER is "less -R".
-#   3. Start GUI apps in bg to unblock. Redirect stdout and strerr if required.
-#   4. Some CLI utilities are piped to the $PAGER, to wait and quit uniformly.
-#   5. If the output cannot be paged use "read -r _" to wait for user input.
-#   6. On a DE, try 'xdg-open' or 'open' in handle_fallback() as last resort.
-#
-#   Feel free to change the utilities to your favourites and add more mimes.
-#
-# Defaults:
-#   By extension (only the enabled ones):
-#      most archives: list with atool, bsdtar
-#      rar: list with unrar
-#      7-zip: list with bsdtar
-#      pdf: zathura (GUI), pdftotext, mutool, exiftool
-#      audio: mocq (nnn plugin using MOC), mpv, media_client (Haiku), mediainfo, exiftool
-#      avi|mkv|mp4: mplayer, mpv (GUI), ffmpegthumbnailer, mediainfo, exiftool
-#      log: vi
-#      torrent: rtorrent, transmission-show
-#      odt|ods|odp|sxw: odt2txt
-#      md: glow (https://github.com/charmbracelet/glow), lowdown (https://kristaps.bsd.lv/lowdown)
-#      htm|html|xhtml: w3m, lynx, elinks
-#      json: jq, python (json.tool module)
-#   Multimedia by mime:
-#      image/*: imv/sxiv/nsxiv (GUI), viu (https://github.com/atanunq/viu), img2txt, exiftool
-#      video/*: mplayer, mpv (GUI), ffmpegthumbnailer, mediainfo, exiftool
-#      audio/*: mocq (nnn plugin using MOC), mpv, media_client (Haiku), mediainfo, exiftool
