# Description: Fuzzy find and execute nnn plugins (and, optionally, custom scripts located elsewhere).
# Description and details of plugins can be previewed from the fzf interface. Use `?` to toggle preview
# pane on and off.
#
# For better compatibility with as many nnn plugins as possible, fzfplug will first execute
# the chosen script on the file hovered in nnn, and upon failure, try to run it with no target
# (which should actually run it on selected files if nnn has an active selection). I don't
# have the required dependencies to confirm compatibility with all scripts though.
#
# Dependencies: find, fzf, cat (or bat, if installed)
# Shell: POSIX compliant
# Author: Kabouik
# OPTIONAL SCRIPTS SOURCES
# Leave blank or fill with the absolute path of a folder containing executable scripts other than nnn plugins
# (e.g., "$HOME/.local/share/nautilus/scripts", since there are numerous Nautilus script git repositories).
