# Description: Text based file previewer
|
||
|
|
#
|
||
|
|
# Note: This plugin needs a "NNN_FIFO" to work.
|
||
|
|
#
|
||
|
|
# Dependencies: tmux or xterm (or set $TERMINAL), file, tree
|
||
|
|
#
|
||
|
|
# How to use:
|
||
|
|
# You need to set a NNN_FIFO path and set a key for the plugin,
|
||
|
|
# then start `nnn`:
|
||
|
|
#
|
||
|
|
# $ NNN_FIFO=/tmp/nnn.fifo nnn
|
||
|
|
#
|
||
|
|
# Then in `nnn`, launch the `preview-tui` plugin.
|
||
|
|
#
|
||
|
|
# If you provide the same NNN_FIFO to all nnn instances, there will be a
|
||
|
|
# single common preview window. I you provide different FIFO path, they
|
||
|
|
# will be independent.
|
||
