# #############################################################################
# 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' 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 7z
# pdf: zathura (GUI), pdftotext, mutool, exiftool
# audio: mocplay (nnn plugin using MOC), mpv, media_client (Haiku), 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, media_client (Haiku), 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
