Add an expression evaluator (REPL support with inspector sequent results)

[rohanrhu]

Describe the project you are working on

Meow... I made an expression evaluator:

godotengine/godot#60134

Describe the problem or limitation you are having in your project

We need an expression evaluator in debugger, it is a very common need 😊

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

The evaluator has sequent results for expressions. It can get locals and members. When you click objects on results, it opens the object on inspector.

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

Evaluator is using Expression class.

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

Meow

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

Is there any active development going on for this issue? I see that it has been bumped to 4.3, but none of the dev snapshots of 4.3 mentions anything about debugging. Just curious about what the current state is.

The pull request needs to be rebased, but since 4.3 is entering its beta stage soon (where no large new features may be added), I doubt it'll make it for 4.3.

Hi @Calinou, I made the latest requests but seems like (I'm not %100 sure though) a weird behavior is coming from inspector component's internal behavior; it is refreshing expression values when debugger's current stack frame is changed.

Sorry if this is a dumb question, this is available now? Or not until godot 4.4? Currently have godot 4.3 installed and would like to use this feature

It's in 4.4, you can test it out in 4.4 dev 3 (https://godotengine.org/article/dev-snapshot-godot-4-4-dev-3/) or wait for the full 4.4 release.
