After this (IMHO) successful presentation at FOSDEM, people spontaneously offered their help.  Many more showed their interest into the ideas or to use it.  Let’s see what is developing from that.

For the new readers, libchamplain is a Clutter based map displaying widget.  It intends to be a light embeddable map widget for all applications with nice eye candy.  For instance, the current API concentrates on how to draw markers and display maps rather than parsing raw GPX data.

Some days before FOSDEM, work started on libchamplain 0.3.  This version will be the development version leading to libchamplain 0.4 (kind of using the same numbering schema than Clutter).  Along with all the promised features (routes, custom map sources and being bindings friendly), this version will have a better code base.  It is already much cleaner than the 0.2 series, and yet a lot of work is left to be done.  I had written a MVC version of the code and I am slowly merging this work (from the MVC branch) back into master.  Also, one of the biggest change is that libchamplain and libchamplain-gtk are now under the same git tree.  Packagers will hate us a little now, but it should provide simpler to maintain in the future.  All bindings will also be under the same tree, in the bindings directory.

There is a new demo portraying an animated marker. See demos/animated-marker.c.

Anders Mørk-Pedersen has been around before FOSDEM working on managed bindings for libchamplain.  With Stéphane Delcroix special touch, they got them running.  They are merged, and I think, ready to be tested.  Now, I am not telling you yet what those bindings are going to be used for… 

Denk Padje offered his help working on the python bindings.  While we got somethings to generate, neither of us are python specialist.  We could use some help.  The branch is bindings-python.  Once the bindings are running, examples will be written.

Libchamplain could certainly profit from Google’s Summer of Code.  Ideas such as having map drawn locally from raw map data and supporting more map sources and map projections (at least one that doesn’t make Greenland the size of South America) will probably be added to Gnome’s pool of ideas.

Now that we have a mailing list, I think a proper web site should come next.  I would also like the project to have a neat logo.  But nothing too fancy as it is a library after all.  May be someone could come up with something like likes of Geoclue’s logo, but may be as a puzzle piece (clearly indicating that it is a library).  Also, I like the Tango colors

That’s it for Febuary.

Marc spent weeks implementing NPAPI plugins support in QtWebKit, now that Qt 4.5 is available as a release candidate, you can now enjoy the work he did for Collabora. Be sure to read his post, it’s more interesting hehe.

Update: it turns out I forgot to mention that Rodney Dawes has worked on NPAPI plugins for WebKitGtk+ for months, but Marc completed the work, and ported it to Qt too.  Therefore, Rodney also deserves congratulations!

This week-end, I presented a talk at FOSDEM about how “Bringing geolocation into GNOME”.  While giving some background definitions and ideas for geolocation, it mostly covered what are technologies currently available to achieve these goals.

I have the impression that the talk was well received, it certainly boosted my interest into spending long nights infront of the screen pushing libchamplain forward much more!

All of the demonstrated code is already available.  For EOG plugin, see the EOG-plugins svn repo, a release should be available in the Gnome 2.28 timeframe.  For the Empathy Geolocation, it is available in my empathy repo, and the telepathy parts already have been released.  This feature should be merged first thing in the 2.27 development cycle, allowing a smooth testing period before 2.28.  As for Emerillion, it was the first public mention of this promizing application.  It shall be announced in a close future.

To make this presentation, I used clutter-toys/opt, a clutter based presentation tools.  The slides are defined in a xml file.  I enhanced it to support embedded maps.  So if you add the following xml code, you’ll have an interactive map of Brussels, with very usefull places marked, right into your slide! Grab the branch into my clutter-toys repo.
