I added Vala bindings for libmemphis yesterday.
You can download the latest version (0.2.2) from here:
I will add support for it in Champlain, if you don't want to support it.

There are also Python bindings for libmemphis here:

In my opinion it would be best to distribute them together with
libmemphis too so people don't have to download too many separate
packages. Discuss it with Victor what's his opinion about that.



Oh, great. I will add it to the Memphis wiki.

Sorry.. this patch was to quickly - I forgot to rebuild the .gi file.
Now the problem is that libmemphis also needs Vala bindings if we want
to build the complete bindings. For now I will try to manually remove
libmemphis stuff and I will deal with this later.

I have ported Vala bindigns from latest 0.4 to 0.6. Because I am
unsure in what way you prefer that we send you the patches I will send
it here. Please include it in the next 0.6 branch release. I will
prepare patches also for 0.7 development but I would like to
experiment first how to make automatic bindings building.

regards, Tomaž

Hello everyone,

libchamplain 0.6 is out. There hasn't been much exciting since 0.5.2;
here's a brief list of changes:

* Add dummy ChangeLog file (Łukasz Jernaś)
* Fix a problem on some machines when tiles are being destroyed (Jiří
* Add minimal demos (Jiří Techet)
* Some other minor fixes (Jiří Techet)

For more details refer to git log.

This is probably the right place to point out several
incompatibilities with the 0.4 branch. There have been many changes in
the API so it's possible you encounter some errors while compiling
your program, but these should be easy to fix. However, there are two
gotchas if you are upgrading from the previous stable release mainly
because your sources will compile just fine, but when running it,
unexpected things happen:

1. ChamplainMapSource and ChamplainPolygon inherit from
GInitiallyUnowned now and g_object_ref_sink() is called on them. The
practical consequence is that you MUST NOT call g_object_unref() once
you insert them to ChamplainView, otherwise your application will
crash. libchamplain takes ownership of them so you don't have to care
about their deallocation any more.

2. If you want to create a cached map source, call
champlain_map_source_factory_create_cached_source() instead of
champlain_map_source_factory_create(). The latter function will just
create the bare map source without any caching. So if it seems to you
the tiles don't get cached, this is probably the cause.

We're late with this release but I'll do my best to follow the gnome
schedule for the following release. In a few days I'll send a few
ideas what I'd like to have implemented for 0.8.
