# 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. mocq 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:
|
|
# 1. by extension
|
|
# 2. by mime (image, video, audio, pdf)
|
|
# 3. by mime (other file types)
|
|
# 4. by mime (prompt and run executables)
|
|
#
|
|
# 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.
|
|

|
