3# #############################################################################
4# Description: Sample script to play files in apps by file type or mime
5#
6# Shell: POSIX compliant
7# Usage: nuke filepath
8#
9# Integration with nnn:
10# 1. Export the required config:
11# export NNN_OPENER=/absolute/path/to/nuke
12# # Otherwise, if nuke is in $PATH
13# # export NNN_OPENER=nuke
14# 2. Run nnn with the program option to indicate a CLI opener
15# nnn -c
16# # The -c program option overrides option -e
17# 3. nuke can use nnn plugins (e.g. mocplay is used for audio), $PATH is updated.
18#
19# Details:
20# Inspired by ranger's scope.sh, modified for usage with nnn.
21#
22# Guards against accidentally opening mime types like executables, shared libs etc.
23#
24# Tries to play 'file' (1st argument) in the following order:
25# i. by extension
26# ii. by mime (image, video, audio, pdf)
27# iii. by mime (other file types)
28#
29# Modification tips:
30# 1. Invokes CLI utilities by default. Set GUI to 1 to enable GUI apps.
31# 2. PAGER is "less -R".
32# 3. Start GUI apps in bg to unblock. Redirect stdout and strerr if required.
33# 4. Some CLI utilities are piped to the $PAGER, to wait and quit uniformly.
34# 5. If the output cannot be paged use "read -r _" to wait for user input.
35# 6. On a DE, try 'xdg-open' in handle_fallback() as last resort.
36#
37# Feel free to change the utilities to your favourites and add more mimes.
38#
39# Defaults:
40# By extension (only the enabled ones):
41# most archives: list with atool, bsdtar
42# rar: list with unrar
43# 7-zip: list with 7z
44# pdf: zathura (GUI), pdftotext, mutool, exiftool
45# audio: mocplay (nnn plugin using MOC), mpv, mediainfo, exiftool
46# avi|mkv|mp4: smplayer, mpv (GUI), ffmpegthumbnailer, mediainfo, exiftool
47# log: vi
48# torrent: rtorrent, transmission-show
49# odt|ods|odp|sxw: odt2txt
50# md: glow (https://github.com/charmbracelet/glow), lowdown (https://kristaps.bsd.lv/lowdown)
51# htm|html|xhtml: w3m, lynx, elinks
52# json: jq, python (json.tool module)
53# Multimedia by mime:
54# image/*: imv/sxiv (GUI), viu (https://github.com/atanunq/viu), img2txt, exiftool
55# video/*: smplayer, mpv (GUI), ffmpegthumbnailer, mediainfo, exiftool
56# audio/*: mocplay (nnn plugin using MOC), mpv, mediainfo, exiftool
57# application/pdf: zathura (GUI), pdftotext, mutool, exiftool
58# Other mimes:
59# text/troff: man -l
60# text/* | */xml: vi
61# image/vnd.djvu): djvutxt, exiftool
62#
63# ToDo:
64# 1. Adapt, test and enable all mimes
65# 2. Clean-up the unnecessary exit codes
