Yep. Doesn't work.

[Vala] vala, libpeas, GIR
Hi there,
I've been playing around with vala, libpeas, and plugins loaded on
the fly through libseed (javascript) and python.
The way you make plugins in libpeas is through extensions. These
can be defined through an interface. It looks something like this:
public interface MyActivatable : Object {
public abstract ScriptableWindow window { get; set; }
public abstract void activate ();
public abstract void deactivate ();
}
Since libpeas doesn't really handle Vala code, I've been trying to
write vala that compiles close to the same C code that libpease
wants.
The above interface works to some extent, but I did
noticed that the GIR file that vala produces is not the same as
what libpeas has. They have a default interface called Activatable
whos GIR file looks like so (section):
field name=activate
callback name=activate
return-value transfer-ownership=none
type name=none c:type=void/
/return-value
parameters
parameter name=activatable transfer-ownership=none
type name=Activatable c:type=PeasActivatable*/
/parameter
/parameters
/callback
/field
The GIr that vala produces looks like this however:
callback name=my_activatable_activate
c:type=my_activatable_activate
return-value transfer-ownership=none
type name=none/
/return-value
/callback
It is missing the field tags altogether. Since they are using some
sort
of automatic means of generating the GIR file, I wonder where these field
statems come from. I was told on the #libpeas IRC that the GIR creation is off
in vala. Any ideas or help on this?
There is something wrong in the GIR that causes all python plugins to
crash when they use MyActivatable instead of the default Activatable from
libpeas.
thanks -august.
