Re: GIR-based vala bindings

[Jiří Techet <techet gmail com>]

Hi Lorenzo,

any progress with this? At the moment the vala bindings in
libchamplain are quite outdated and it would be quite a lot of work to
bring them up to date which I'd like to avoid. If the vala branch for
using girs for binding generation is usable, we could use it to
generate the vapi's even though it's not released yet. All we need are
the vapi's which can then be distributed with libchamplain so normal
users don't have to generate them.

Even if the vapi generation isn't ready yet, is there anything I
should pull from your branch before the 0.10 release (which I plan to
make in about a week)?

Cheers,

Jiri
