GDScript: Improve highlighting of types

[dalexeev]

• Fixes Variant in for loop is not colour coded. #82506.
• Fixes Missing cases of Variant type syntax highlighting #82775.

1. Fix highlighting of for loop variable type.
2. Highlight void, bool, int, and float as types, not as keywords. This is especially good when there is another keyword next to the type (like if a is int or a is float).
3. Fix highlighting of type chains (like Variant.Type).
4. Add Ctrl+Click for Variant.

This also resolves #44922 🙂

#82326 is still relevant and not superseded.

Code looks good to me. I'm surprised to see void highlighted as a type - it both makes and doesn't make sense to me as a user. Given the context it always pops up in, I think it's better this way.

Good lord, thank you for making the numeric types green, it was bothering me for so long.

Is it possible to look into this also, if not let me know, I can create a separate issue.

set and get are not colored.

Thanks

Is it possible to look into this also

Given the way highlighter works, the only solution I see is to highlight all set and get identifiers as method calls. This won't affect identifier parts (like set_name), string literals, comments, etc., but set and get will be highlighted as method calls even without parentheses (if you pass them as Callables). But I think it has more pros than cons.

I think get and set are not keywords because they can be method names.
In that case it is ok.
Ideally I thought get and set when not methods(without parentheses) should be treated(highlight only) like keywords

[dalexeev]

Highlighting set and get as keywords or as method definitions depending on the context is possible, but it is more difficult. I think the simple solution looks good for now.
