+#!/usr/bin/env bash
+
+# Description: Terminal based file previewer
+#
+# Note: This plugin needs a "NNN_FIFO" to work. See man.
+#
+# Dependencies:
+#   - Supports 6 independent methods to preview with:
+#       - tmux (>=3.0), or
+#       - kitty with allow_remote_control and listen_on set in kitty.conf, or
+#       - wezterm (https://wezfurlong.org/wezterm), or
+#       - QuickLook on WSL (https://github.com/QL-Win/QuickLook), or
+#       - Windows Terminal (https://github.com/Microsoft/Terminal | https://aka.ms/terminal) with WSL, or
+#       - $NNN_TERMINAL set to a terminal (it's xterm by default).
+#   - less or $NNN_PAGER
+#   - tree or exa or (GNU) 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, wezterm terminal, viu, catimg or chafa for images
+#   - optional: convert(ImageMagick) for playing gif preview (required for kitty image previews)
+#   - 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: djvulibre for djvu
+#   - optional: glow or lowdown for markdown
+#   - optional: w3m or lynx or elinks for html
+#   - optional: set/export NNN_ICONLOOKUP as 1 to enable file icons in front of directory previews with .iconlookup
+#       Icons and colors are configurable in .iconlookup
+#   - optional: scope.sh file viewer from ranger.
+#       1. drop scope.sh executable in $PATH
+#       2. set/export $NNN_SCOPE as 1
+#   - optional: pistol file viewer (https://github.com/doronbehar/pistol).
+#       1. install pistol
+#       2. set/export $NNN_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 launch the `preview-tui` plugin in `nnn`.
+#
+#   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 ($NNN_TERMINAL).
+#
+#   Kitty users need something similar to the following in their kitty.conf:
+#   - `allow_remote_control yes`
+#   - `listen_on unix:$TMPDIR/kitty`
+#   - `enabled_layouts splits` (optional)
+#   With ImageMagick installed, this terminal can use the icat kitten to display images.
+#   Refer to kitty documentation for further details.
+#
+#   Wezterm should work out of the box. If `NNN_PREVIEWIMGPROG` is not specified it will use
+#   built in iTerm2 image protocol.
+#
+#   Note that GNU ls is used for its `--group-directories-first` flag.
+#   On MacOS this may be installed with `brew install coreutils`, or the flag can be removed.
+#   iTerm2 users are recommended to use viu to view images without getting pixelated.
+#
+#   Windows Terminal users can set "Profile termination behavior" under "Profile > Advanced" settings
+#   to automatically close pane on quit when exit code is 0.
+#
+#   When specifying a different terminal, additional arguments are supported. In particular, you can
+#   append a specific title to the terminal and set it to "nofocus" in your WM config.
+#   E.g for alacritty and i3, you can set $NNN_TERMINAL to 'alacritty --title preview-tui' and add
+#   'no_focus [title="preview-tui"]' to your i3 config file.
