# 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.
