|
|
# 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 enbaled 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)
|
|
# htm|html|xhtml: w3m, lynx, elinks
|
|
# json: jq, python (json.tool module)
|
|
# Multimedia by mime:
|
|
# image/*: sxiv (GUI), 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 unnecessary the exit codes
