Expose Script.get_global_name()

[theraot]

Describe the project you are working on

This applies to a couple addons:

• A custom binary serializer
• A code generator

There are also some other places that would benefit from a "nameof" operator, but that is a different case.

Describe the problem or limitation you are having in your project

I need to find the name of an arbitrary class given a reference.

Describe the feature / enhancement and how it helps to overcome the problem or limitation

Apparently this already exists in get_global_name, but it is not exposed to scripting. Thus, expose it to scripting.

Describe how your proposal will work, with code, pseudo-code, mock-ups, and/or diagrams

Expose get_global_name to scripting.

If this enhancement will not be used often, can it be worked around with a few lines of script?

We can work around it for GDScript like this:

	var result := ""
	for global_class in ProjectSettings.get_global_class_list():
		if str(global_class["path"]) == script.resource_path:
			result = str(global_class["class"])
			break

However, that is only for GDScript. The method get_global_name exists in Script, and so it would also work for CSharpScript and any other future - or third party - derived class.

Is there a reason why this should be core and not an add-on in the asset library?

The method get_global_name is in core.

Tangentially related:

• get_class() and is_class() not returning class_name godot#21789
• get_class() returns wrong name, breaks signal connections, C++/GDExtension godot#69270

We can work around it for GDScript like this [...] However, that is only for GDScript. The method get_global_name exists in Script, and so it would also work for CSharpScript and any other future - or third party - derived class.

ProjectSettings.get_global_class_list() should retrieve all registered global classes regardless of its scripting language. So it should already be working with CSharpScript. Maybe I misunderstood what you meant.

@raulsntos In all honesty, I was convinced it didn't, but I didn't check before posting. Thank you.
