About

Chafa is a command-line utility that converts image data, including
animated GIFs, into graphics formats or ANSI/Unicode character art suitable
for display in a terminal. It has broad feature support, allowing it to be
used on devices ranging from historical teleprinters to modern terminal
emulators and everything in between.

The core functionality is provided by a C library with a public,
well-documented API.

Both library and frontend tools are covered by the Lesser GPL license,
version 3 or later (LGPLv3+).

The official web pages and C API
documentation can be found online. Check
out the gallery for screenshots.

Installing

Chafa is most likely packaged for your distribution, so if you're not
going to hack on it, you're better off using
official packages. If you want to
build the latest and greatest yourself, read on.

You will need GCC, make, Autoconf, Automake, Libtool and the GLib
development package installed to compile Chafa from its git repository. If
you want to build the command-line tool chafa and not just the library,
you will additionally need development packages for:

• FreeType2. Often packaged as libfreetype6-dev or freetype2-devel.
• libjpeg (optional). Look for libjpeg-dev, libjpeg62-devel or libjpeg8-devel.
• librsvg (optional). Look for librsvg2-dev or librsvg-devel.
• libtiff (optional). Look for libtiff5-dev or libtiff-devel.
• libwebp (optional). Look for libwebp-dev or libwebp-devel.

If you want to build documentation, you will also need gtk-doc.

Start by cloning the repository:

$ git clone https://github.com/hpjansson/chafa.git

Then cd to the toplevel directory and issue the following shell commands:

$ ./autogen.sh
$ make
$ sudo make install

That should do it!
