# nlay: a customizable script to play files in different apps by file type
#
# usage: nlay file type
#
# MUST READ:
#
# 1. Feel free to change the default apps to your favourite ones.
#    If you change the app for a group you may also need to modify the bg
#    setting. If bg is set the app is detached and started in the background in
#    silent mode.
#
#    The bg setting depends on personal preference and type of app, e.g.,
#    I would start vim (CLI) in the foreground but Sublime Text (GUI) in the
#    background. I also prefer mpv running in the background without disturbing
#    my ongoing activity in nnn by blocking navigation.
#
#    Check (and TOGGLE as you wish) the default bg settings.
#
# 2. Detached apps are not killed when nnn exits. Use kill(1) or killall(1) to
#    to stop console based background apps.
#
# 3. Assuming you don't to play multiple audio/video files simultaneously,
#    nlay kills any running instances of the audio/video player in bg mode.
#
# 4. Keep a personal backup (on GitHub Gist maybe?) of this file if you modify
#    it. nlay is OVERWRITTEN during nnn upgrade.
