# 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, ^Up/^Dn to scroll.
#
# Dependencies: find, fzf, cat (or bat, if installed)
2021-05-15 17:32:01 +00:00
#
# Note: For better compatibility with as many nnn plugins as possible,
# fzplug will first execute the chosen script on the file hovered
# in nnn, and upon failure, try to run it with no target (i.e on
# an active selection, if present).
