# 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.
# Simple use 'run_fg' or 'run_bg' to run the specified app with the given
# options in foreground or background respectively. Variable '$1' contains
# path of the file to open. If run_bg is used the app is detached and
# started in the background in silent mode. If the app is not installed
# (i.e. is not on your PATH), it is silently skipped and the script tries
# next 'run_bg' or 'run_fg'.
#
# The 'run_bg' vs. 'run_fg' 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.
#
# 2. Detached apps are not killed when nnn exits. Use kill(1) or killall(1) to
# to stop console based background apps.
#
# 3. nlay is OVERWRITTEN during nnn upgrade. You can store your custom nlay in a
# location other than the default and have an alias with nnn option '-p' to
# invoke it. Remember it might break or lack new capabilities added to nlay
# in future releases. Check the file diff once in a while.
#
# Please note that this is not the original nlay script, but Alpine version
# rewritten to be compatible with any POSIX compliant shell, not just Bash/ZSH.
