I'm trying to find a friendly syntax for defining things in a
framework. For context, I've been looking into finding a solution
for this problem
(https://github.com/GodotNativeTools/godot-d/issues/1) on the
Godot-D project. I've done some investigating already, and it
looks like I can only achieve what I want with a mixin, but I'd
like to get a second opinion.
Say we have a class that defines a custom Signal (an event). In
an ideal world, the syntax would work similarly to this:
class SomeNode : GodotScript!Node
{
@Signal void testSignal(float a, long b);
// The declaration above would trigger the generation of this
line
void testSignal(float a, long b) {
owner.emitSignal("testSignal", a, b); }
@Method emitTest()
{
testSignal(3.1415, 42);
}
}
The reason I want to use a UDA is to stay consistent with the
other UDAs already defined for Properties and Methods. It also
looks friendlier than using a mixin. Does anyone here have any
thoughts as to how this could work?
My main issue is injecting that generated method without
resorting to using a mixin. I was hoping that any code I needed
could be generated in the template that SomeNode inherits, but
that doesn't look possible because I can't inspect the subclass
(for good reason).
