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+).
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 the ImageMagick development packages.
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!
