New module proposal: libpeas

Hello Gnomers,

I'd like to propose libpeas as part of the desktop release set, or whatever the release team cooked to replace it in Gnome 3.0.

libpeas is a library targetted at native applications in Gnome and allowing them to easily provide extensibility through either a C GModule or gobject-introspection-based bindings (currently, either pygi or seed). It is meant to replace the old Gedit Plugins Engine which got copy-and-pasted in too many applications.


Libpeas currently depends on the latest gtk+ of the 3.0 branch, and on gobject-introspection 0.9.6. It optionally depends on pygobject 2.20 (for python support) and seed 2.28 (for javascript support).

That's all.


As of today, libpeas is used in several applications already member of the release set in their master branch, to be used in Gnome 3.0:
 - totem
 - gedit
 - vinagre
 - nautilus-sendto

Several other maintainers have expressed their interest in using libpeas.


Libpeas comes from gedit, and uses the gnome infrastructure (bugzilla, git, ftp, irc, mailing-list) since the very beginning.

We express ourselves in a clean GObject-based API and provide a separate library for Gtk+ 3.0 integration.

3.0 readiness:

Relevant because many apps plan to use libpeas for 3.0 in order to make their own codebase simpler.

Having a single library also makes it easier to integrate with other tools, such as an eventual website.

We only use the latest Gnome libraries available, so we build fine using the latest GLib, Gtk+ and gobject-introspection.


LGPL 2.1+ for all the code base.

API/ABI stability.

I think most of the API work is done now and from now on I hope being able to provide additional features without breaking the C API for applications.

Python and seed binding stability is bound to gobject-introspection and respective bindings so I cannot make any promise yet for those.
