|
# nplay: a sample script to play files in different apps by file type and mime |
|
|
|
# shell: POSIX compliant |
|
|
|
# usage: nplay filepath |
|
|
|
# |
|
|
|
# nnn integration: |
|
|
|
# 1. Export the required config: |
|
|
|
# export NNN_OPENER=/path/to/nplay |
|
|
|
# # Otherwise, if nplay is in $PATH |
|
|
|
# export NNN_OPENER=nplay |
|
|
|
# 2. Run nnn with the program option to indicate a CLI opener |
|
|
|
# nnn -c |
|
|
|
# 3. nplay 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. |
|
|
|
# |
|
|
|
# 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 |
|
|
|
# m4a: mocplay (nnn plugin using MOC), mpv, mediainfo, exiftool |
|
|
|
# torrent: transmission-show |
|
|
|
# odt|ods|odp|sxw: odt2txt |
|
|
|
# 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/* | */xml: vi |
|
|
|
# image/vnd.djvu): djvutxt, exiftool |
|
|
|
# |
|
|
|
# ToDo: |
|
|
|
# 1. Adapt, test and enable all mimes |
|
|
|
# 2. Clean-up unnecessary the exit codes |
