Feature/func renaming

[you-win]

• Modify func macro to accept a 'rename = ...' attribute
• Add integration tests to cover renamed functions

Comments

Continuing from the previous PR as GitHub (sensibly) closes the PR if you change the branch name, and I wasn't able to re-open the PR.

Please let me know if it would be better to break this functionality out like with field_var.rs. I tried to keep the number of changed files to a minimum.

There are also TODOs left in the file as a starting point for discussion, but feel free to start picking at the PR wherever you want. Most have been resolved. There is a TODO left in the code to indicate where default values on the GDScript side might be implemented.

Still todo

• signal renaming
• docs
• unit tests? Covered by integration tests
• type alias Function to Signal for readability?
• location of FuncDefinition in src/method_registration/mod.rs is okay?
• refactor of src/godot_api.rs:extract_attributes is okay?

API docs are being generated and will be shortly available at: https://godot-rust.github.io/docs/gdext/pr-378

Thanks for the update!

I don't think many people care about the branch name 😉 the PR title is more important. In the future, please try to keep it in one pull request, because now all the review and change history is gone, which makes things a bit harder to follow.

Will squash the commits once godot_api::extract_attributes discussion is resolved.

[you-win]

Ready for re-review.

Changes from the initial reviews have been made sans the extract_attributes refactor.

• remove type alias for Signal attributes
• split out GodotFn into a reusuable struct as FuncDefinition
• handle parser.handle_expr errors properly and also appease clippy lint

Thanks a lot for the feature and all the amendments 🙂
