ctpv

File previewer for a terminal

ctpv is a file previewer utility for a terminal.

It was made with integration into lf file manager in mind, but I believe that it can be easily integrated into other programs as well.

It supports previews for source code, archives, PDF files, images, videos, etc. See Previews for more info.

Image previews are powered by one of these programs:

Überzug (X11 only)
Chafa (X11 and Wayland)
Kitty terminal

ctpv is a remake of an awesome program named stpv. stpv did everything I wanted, except it was a bit sluggish because it was written in POSIX shell. ctpv is written in C and is an attempt to make a faster version of stpv with a few new features.

Previews

Previewing each file type requires specific programs installed on a system. If a program is not found on the system, ctpv will try to use another one. Only one program is required for each file type. For example, you only need either elinks, lynx or w3m installed on your system to view HTML files.

File types	Programs
any	exiftool cat
archive	atool
audio	ffmpegthumbnailer ffmpeg
diff	colordiff delta diff-so-fancy
directory	ls
font	fontimage
gpg-encrypted	gpg
html	elinks lynx w3m
image	ueberzug chafa
json	jq
markdown	glow mdcat
office	libreoffice
pdf	pdftoppm
svg	convert
text	bat cat highlight source-highlight
torrent	transmission-show
video	ffmpegthumbnailer

If you don't need to call it directly and just want to use it through lf:

programs.lf = {
  previewer = {
    keybinding = "i";
    source = "${pkgs.ctpv}/bin/ctpv";
  };
  extraConfig = ''
    &${pkgs.ctpv}/bin/ctpv -s $id
    cmd on-quit %${pkgs.ctpv}/bin/ctpv -e $id
    set cleaner ${pkgs.ctpv}/bin/ctpvclear
  '';
}

Gentoo

Add this ctpv-9999.ebuild to your own repository.

Or alternatively:

eselect repository add sneethe-overlay git https://github.com/Sneethe/sneethe-overlay.git
emaint sync --repo sneethe-overlay
emerge --ask --verbose app-misc/ctpv

Integration

lf file manager

Add these lines to your lf config (usually located at ~/.config/lf/lfrc).

set previewer ctpv
set cleaner ctpvclear
&ctpv -s $id
&ctpvquit $id

Wayland

If you use Wayland, follow these steps:

Make sure you use one of the terminals that support sixel
Install this fork of lf
Install Chafa
Add set chafasixel to ~/.config/ctpv/config

As of 2023-03-19, original lf does not support sixel protocol, which is why you need use the fork.
