#!/usr/bin/env sh
# Description: Independent POSIX-compliant GUI application launcher.
# Fuzzy find executables in $PATH and launch an application.
# stdin, stdout, stderr are suppressed so CLI tools exit silently.
#
# To configure launch as an independent app launcher add a keybind
# to open launch in a terminal e.g.,
#
# xfce4-terminal -e "${XDG_CONFIG_HOME:-$HOME/.config}/nnn/plugins/launch
#
# Dependencies: fzf
#
# Usage: launch [delay]
# delay is in seconds, if omitted launch waits for 1 sec
#
# Integration with nnn: launch is installed with other plugins, nnn picks it up.
#
# Shell: POSIX compliant
# Author: Arun Prakash Jana
