|\ | | | | | | | | | | | | | | | | | | 6901: Temp fixes panic caused by no ast for proc-macro r=maklad a=edwin0cheng There are some panic when hover/goto definition for proc-macro. It is because in current design, we don't have `ast-node` for proc-macro and then it trigger [this](https://github.com/rust-analyzer/rust-analyzer/blob/479d1f7eec22c3564867223e2093f14774092528/crates/hir/src/has_source.rs#L116) line to panic. This PR is a temp fix for all of these similar to https://github.com/rust-analyzer/rust-analyzer/blob/bd4c352831662762ee7a66da77ec9adf623b0a0a/crates/completion/src/render/macro_.rs#L42 Co-authored-by: Edwin Cheng <[email protected]>

Intellij is able to refresh the completions on every new symbol added, yet VS Code does not query the completions on every symbol for me. With a few debug prints placed in RA, I've observed the following behaviour: after the first set of completion suggestions is received, next symbol input does not trigger a server request, if the completions contain this symbol. When more symbols added, the existing completion suggestions are filtered out until none are left and only then, on the next symbol it queries for completions. It seems like the only alternative to get an updated set of results is to manually retrigger it with Esc and Ctrl + Space. Despite the eerie latter bullet, the completion seems to work pretty fine and fast nontheless, but if you have any ideas on how to make it more smooth, I'll gladly try it out.

|/ | | | | | | | Declaration names sounds like a name of declaration -- something you can use for analysis. It empathically isn't, and is just a label displayed in various UI. It's important not to confuse the two, least we accidentally mix semantics with UI (I believe, there's already a case of this in the FamousDefs at least).

After a third try, it finally works. Boy, it appeared tougher than it seemed. Initially I thought like "Ha, `rustc` already tells us where idents are named incorrectly. It shouldn't be that hard, should it?". Well, the problems with the information provided by `rustc` appeared shortly: - `rustc` warnings are `flycheck` warnings, which are slightly aside from our diagnostics with fixes. When we map flycheck diagnostic to LSP, we can convert it into a fix, but only if it's marked as `Applicability::MachineApplicable`. Name case fix is marked `Applicability::MaybeIncorrect`, and for a reason: it only suggest to rename symbol under cursor, without tracking any references. - Warning spawned by `rustc` are identified by string labels rather than enum. It means that if one day the diagnostic will be renamed in `rustc`, `rust-analyzer` code will still compile, but won't find the required diagnostic by name anymore. If by chance this will happen when some unlucky guy will decide to create their first pull request, they'll be confused by suddenly failing tests (likely) not related to their changes. - Even if we'll try to build fixes atop of `rustc` warnings, we'll have to do it in the `rust_analyzer::diagnostics::to_proto` module, which is far less convenient for that matter than `ide` crate. That's why I decided that it's worth a separate `rust-analyzer` diagnostic, which will implement `DiagnosticWithFix` trait. After that, I discovered that currently `hir_ty::diagnostics` only check `DefWithBody` types, like function bodies. I had to add support for diagnostics which look at any `ModuleDef`. And of course, since I'd added a lot of new functionality, it required extensive testing. That explains why the diff is so big for a (looking) relatively small feature. I hope that this PR doesn't only add a small feature, but also creates a base for building another features. ## Example: ![case_quick_fix](https://user-images.githubusercontent.com/12111581/95008475-e07ee780-0622-11eb-9978-62a9ea0e7782.gif) P.S.
