|
||||
# - optional: set/export ICONLOOKUP as 1 to enable file icons in front of directory previews with .iconlookup
|
||||
# Icons and colors are configureable in .iconlookup
|
||||
# - optional: scope.sh file viewer from ranger.
|
||||
# To use:
|
||||
# 1. drop scope.sh executable in $PATH
|
||||
# 2. set/export $USE_SCOPE as 1
|
||||
# - optional: pistol file viewer (https://github.com/doronbehar/pistol).
|

# To use:
|
||||
# 1. install pistol
|
||||
# 2. set/export $USE_PISTOL as 1
|
||||
#
|
||||
# Usage:
|
||||
# You need to set a NNN_FIFO path and a key for the plugin with NNN_PLUG,
|
||||
# then start `nnn`:
|
||||
#
|
||||
# $ nnn -a
|
||||
#
|
||||
# or
|
||||
#
|
||||
# $ NNN_FIFO=/tmp/nnn.fifo nnn
|
||||
#
|
||||
# Then in `nnn`, launch the `preview-tui-ext` plugin.
|
||||
#
|
||||
# If you provide the same NNN_FIFO to all nnn instances, there will be a
|
||||
# single common preview window. If you provide different FIFO path (e.g.
|
||||
# with -a), they will be independent.
|
||||
#
|
||||
# The previews will be shown in a tmux split. If that isn't possible, it
|
||||
# will try to use a kitty terminal split. And as a final fallback, a
|
||||
# different terminal window will be used ($TERMINAL).
|
||||
#
|
||||
# Tmux and kitty users can configure $SPLIT to either "h" or "v" to set a
|
||||
# 'h'orizontal split or a 'v'ertical split (as in, the line that splits the
|
||||
# windows will be horizontal or vertical).
|
||||
#
|
||||
# Kitty users need `allow_remote_control` set to `yes`, and `listen_on` set
|
||||
# to e.g. "$TMPDIR/kitty". To customize the window split, `enabled_layouts`
|
||||
# has to be set to `all` or `splits` (the former is the default value).
|
||||
# This terminal is also able to show images without extra dependencies.
