+# #############################################################################
+# 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. mocplay 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:
+#   i. by extension
+#   ii. by mime (image, video, audio, pdf)
+#   iii. by mime (other file types)
+#
+# 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' 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 7z
+#      pdf: zathura (GUI), pdftotext, mutool, exiftool
+#      audio: mocplay (nnn plugin using MOC), mpv, mediainfo, exiftool
+#      avi|mkv|mp4: smplayer, 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 (GUI), viu (https://github.com/atanunq/viu), img2txt, exiftool
+#      video/*: smplayer, mpv (GUI), ffmpegthumbnailer, mediainfo, exiftool
+#      audio/*: mocplay (nnn plugin using MOC), mpv, mediainfo, exiftool
+#      application/pdf: zathura (GUI), pdftotext, mutool, exiftool
+#   Other mimes:
+#      text/troff: man -l
+#      text/* | */xml: vi
+#      image/vnd.djvu): djvutxt, exiftool
+#
+# ToDo:
+#   1. Adapt, test and enable all mimes
+#   2. Clean-up the unnecessary exit codes
