Re: [Vala] [ANNOUNCE] Vala 0.5.1 - Compiler for the GObject type system

["Christian Hergert" <christian hergert gmail com>]

I'm excited about the addition of yielding values.  I released GTask 0.1.2 last week which is an asynchronous/concurrency library for GObject with similar feel to twisted deferreds.  I would love to be able to yield tasks and have the method re-enter when the task has completed.

Something like this ..

void do_something () yields
{
    // result populated on re-entrance with task's value (g_task_get_result()).
    // also, could throw exception on re-entrance if task errored allowing for async try/catch
    var result = yield new Task<string> (_ => { return some_sync_operation (); });

    stdout.printf ("Result was %s\n", result);
}
