Call a non-existent macro in a function body. ``` fn main() { foo!(); } ``` 2. No diagnostics are raised. An unresolved-macro-call diagnostic is expected. 3. If the macro call is instead outside of the function body, this works as expected. I believe this worked previously and regressed in https://github.com/rust-analyzer/rust-analyzer/pull/7805. **Behavior prior to https://github.com/rust-analyzer/rust-analyzer/pull/7805:** - The unresolved-macro-call diagnostic did not exist. Instead, a macro-error diagnostic would be raised with the text "could not resolve macro [path]". - This was implemented by adding an error to the error sink (https://github.com/rust-analyzer/rust-analyzer/pull/7805/files#diff-50a326c5ae465bd9b31ee4310186380aa06e4fa1f6b41dbc0aed5bcc656a3cb8L657). - The error was propagated through https://github.com/rust-analyzer/rust-analyzer/blob/1a82af3527e476d52410ff4dfd2fb4c57466abcb/crates/hir_def/src/body.rs#L123 eventually reaching https://github.com/rust-analyzer/rust-analyzer/blob/1a82af3527e476d52410ff4dfd2fb4c57466abcb/crates/hir_def/src/body/lower.rs#L569. **Behavior after:** - Instead of writing to the error sink, an UnresolvedMacro error is now returned (https://github.com/rust-analyzer/rust-analyzer/pull/7805/files#diff-50a326c5ae465bd9b31ee4310186380aa06e4fa1f6b41dbc0aed5bcc656a3cb8R631). - The parent caller throws away the error as its function signature is `Option<MacroCallId>` (https://github.com/rust-analyzer/rust-analyzer/pull/7805/files#diff-50a326c5ae465bd9b31ee4310186380aa06e4fa1f6b41dbc0aed5bcc656a3cb8R604). - We instead now reach the warn condition (https://github.com/rust-analyzer/rust-analyzer/blob/1a82af3527e476d52410ff4dfd2fb4c57466abcb/crates/hir_def/src/body.rs#L124) and no diagnostics are created in https://github.com/rust-analyzer/rust-analyzer/blob/1a82af3527e476d52410ff4dfd2fb4c57466abcb/crates/hir_def/src/body/lower.rs#L575. **Fix:** - Make sure to propagate the UnresolvedMacro error. Report the error using the new unresolved-macro-call diagnostic. Co-authored-by: Brandon <[email protected]>

I added an expicit unit test for this, `ide_completion::render::fn_detail_includes_args_and_return_type`, which passes. Lots of other unit tests fail (~60 of them) due to this change, although I believe the failures are purely cosmetic (they were testing the exact format of this output). I'm happy to go update those tests, but before I do that I'd like to make sure this is in fact the format we want for the detail? edit - I realized `UPDATE_EXPECT=1 cargo test` automatically updates `expect!` tests. Big :+1: to whoever worked on that! So I'll go ahead and update all these tests soon. But I still would like to confirm `fn(T, U) -> V` is the desired content in the `detail` field. 8000: Use hir formatter for hover text r=matklad a=oxalica Fix #2765 , (should) fix #4665 Co-authored-by: Josh Mcguigan <[email protected]> Co-authored-by: oxalica <[email protected]>

Use a built in macro in such a way that rust-analyzer fails to expand it. For example: **lib.rs** ``` include!("<valid file but without a .rs extension so it is not indexed by rust-analyzer>"); ``` 2. rust-analyzer highlights the macro call and says the macro itself cannot be resolved even though include! is in the standard library (unresolved-macro-call diagnostic). 3. No macro-error diagnostic is raised. **Root cause for incorrect unresolved-macro-call diagnostic:** 1. collector:collect_macro_call is able to resolve include! in legacy scope but the expansion fails. Therefore, it's pushed into unexpanded_macros to be retried with module scope. 2. include! fails at the resolution step in collector:resolve_macros now that it's using module scope. Therefore, it's retained in unexpanded_macros. 3. Finally, collector:finish tries resolving the remaining unexpanded macros but only with module scope. include! again fails at the resolution step so a diagnostic is created. **Root cause for missing macro-error diagnostic:** 1. In collector:resolve_macros, directive.legacy is None since eager expansion failed in collector:collect_macro_call. The macro_call_as_call_id fails to resolve since we're retrying in module scope. Therefore, collect_macro_expansion is not called for the macro and no macro-error diagnostic is generated. **Fix:** - In collector:collect_macro_call, do not add failing built-in macros to the unexpanded_macros list and immediately raise the macro-error diagnostic. This is in contrast to lazy macros which are resolved in collector::resolve_macros and later expanded in collect_macro_expansion where a macro-error diagnostic may be raised.
