# Description: Terminal based file previewer
|
|
#
|
|
# Note: This plugin needs a "NNN_FIFO" to work. See man.
|
|
#
|
|
# Dependencies:
|
|
# - Supports 4 independent methods to preview with:
|
|
# - tmux (>=3.0), or
|
|
# - kitty with allow_remote_control and listen_on set in kitty.conf, or
|
|
# - QuickLook on WSL (https://github.com/QL-Win/QuickLook)
|
|
# - $TERMINAL set to a terminal (it's xterm by default).
|
|
# - less or $PAGER
|
|
# - tree or exa or ls
|
|
# - mediainfo or file
|
|
# - mktemp
|
|
# - unzip
|
|
# - tar
|
|
# - man
|
|
# - optional: bsdtar or atool for additional archive preview
|
|
# - optional: bat for code syntax highlighting
|
|
# - optional: ueberzug, kitty terminal, viu or catimg for images
|
|
# - optional: convert(ImageMagick) for playing gif preview
|
|
# - optional: ffmpegthumbnailer for video thumbnails (https://github.com/dirkvdb/ffmpegthumbnailer)
|
|
# - optional: ffmpeg for audio thumbnails
|
|
# - optional: libreoffce for opendocument/officedocument preview
|
|
# - optional: pdftoppm(poppler) for pdf thumbnails
|
|
# - optional: gnome-epub-thumbnailer for epub thumbnails (https://gitlab.gnome.org/GNOME/gnome-epub-thumbnailer)
|
|
# - optional: fontpreview for font preview (https://github.com/sdushantha/fontpreview)
|
|
# - optional: glow or lowdown for markdown
|
|
# - optional: w3m or lynx or elinks for html
|
|
# - 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.
|
|
#
|
|
# Shell: POSIX compliant
