Topic: proc macro support

Is there an issue that tracks support for procedural macros in rust-analyzer? I did not find one after a search on GitHub. I recently implemented a proc macro for JSX-like syntax: let html = html!(<div>{text}</div>);. If rust-analyzer executed the procedural macro like rustc does, it could theoretically support features like "go to definition" and "find references" when the cursor is over the identifier text.

You need to enable rust-analyzer.loadOutDir and rust-analyzer.proc_macro in the preferences. (not sure about the exact naming, but autocomplete should show them when editing the json preferences in vscode.

we don't support function-style proc macros yet though, only derives

... do we? :thinking:

Yup, we don't support fun-style proc macros yet
