Dynamic cast: if the object returned by builder.get_object() is

This is... very sad. JIT is cool, because it helps to get rid of

Hi,
this sort of problems existed for ever in vala, another example:

{
int method()
{
return 1;
}
}
// cut here

This is by design. The interface does not inherit another interface,
but is dependent on another intefrace (or class) - it means that to
implement an interface, you have to ensure that all interfaces and a
proper base class are implemented/inherited.

I understand your point of view (the whole idea of sticking to
glib as a layer between vala and everything else is good). I'd then
propose to create c99 bindings: c99.vapi or something. It would not be
portable, just as su

+1. I'm for every change in vala that let's it use more and more gcc
features, and give more control over C code generation.

Hi,
no, you did not understand: I'm not trying to create object from an
interface. I'm having class Foo, that is _NOT_ inheriting Object, but
it's still a typed class, and it's implementing interface IFoo. This is
(or used to be) legal. I'm creating instances of that class, but the

It's not so simple, because you can assign this function as a callback

Generally Vala does not have any usable symbol mangling engine. It's
good, because Vala generates a C api and you obviously don't want to
have obfuscated symbols there (the way that C++ does it is jus

Hi,
I can only speak for myself as I'm vala user, not developer, but I'd
say that you should just pay attention to the code that you're writing.
Vala is not a dynamically typed language, 'var' still has strictly
defined type. When some 'var' represents object, it is possible that

valgrind will work for vala programs, you just have to use it as with

Hi all,
I've today compiled my program with recent valac (from git master), and
just from curiosity I've compared generated C sources with my previous
ones. Vala now makes all *get_type() functions const using G_GNUC_CONST.
I don't know at which version was this feature added (previously I used
0.
Well, I compiled vala from git, and it indeed depends on 0.10 version
of solib, but this library is also built.
Are you sure that your build does not contain libvala-0.10.so.0?

It is possible to define a macro in C, and crwate a vapi binding for

hack though.
