Google Summer of Code 2014


Use the Google Summer of Code Wiki and FAQs for information about the project.

Programming languages

Most MATE applications are written in C. We have also few applications and applets written in Python. Almost all applications have Python bindings generated with GObject introspection.

This section lists some ideas for MATE Desktop GSoC projects that students can apply for.


ePub format support in Atril

Brief explanation: Atril is the MATE document viewer and already has support for a variety of document formats: PostScript (PS), Encapsulated PostScript (EPS), DJVU, DVI, Portable Document Format ( PDF) and Open XML Paper Specification (XPS). We would like to add support to open also EPUB files. EPUB is a short for “electronic publication”, it is a free and open e-book standard by the International Digital Publishing Forum (IDPF).

Knowledge prerequisite: C.

Difficulty level: Medium.

GStreamer-1.0 support

Brief explanation: GStreamer is a multimedia framework. MATE currently supports GStreamer 0.10, but this version now is no longer maintained. GStreamer 1.0 includes a lot of improvements and new features, but it is not API or ABI compatible with the 0.10. We would like to add support for this new version of GStreamer.

Knowledge prerequisites: C (GStreamer framework a plus).

Difficulty level: Medium.

Plugin system in Caja

Brief explanation: Caja, our file manager, has a nice library to allow developers to create extensions. But these extensions are loaded during Caja start, and there is no possibility to enable/disable them at runtime. Add a way to enable and disable Caja extensions is one of the goals of MATE Desktop roadmap.

Knowledge prerequisite: C (GLib and GTK a plus).

Difficulty level: Medium.
