|\ | | | | | | | | | | | | | | | | | | | | | | 4851: Add quickfix to add a struct field r=TimoFreiberg a=TimoFreiberg Related to #4563 I created a quickfix for record literals first because the NoSuchField diagnostic was already there. To offer that quickfix for FieldExprs with unknown fields I'd need to add a new diagnostic (or create a `NoSuchField` diagnostic for those cases) I think it'd make sense to make this a snippet completion (to select the generated type), but this would require changing the `Analysis` API and I'd like some feedback before I touch that.

|\ \ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 4937: Allow overriding rust-analyzer display version r=matklad a=oxalica The build script invokes `git` for version information which is displayed when rust-analyzer is called with `--version`. But in build environment without `git` or when the source code is not a git repo, there's no way to manually specify the version information. This patch respects environment variable ~`REV`~ `RUST_ANALYZER_REV` in compile time for overriding. Related: https://github.com/NixOS/nixpkgs/pull/90976 Co-authored-by: oxalica <[email protected]>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The task of `partition` function is to bin the flat list of paths into disjoint filesets. Ideally, it should be incremental -- each new file should be added to a specific fileset. However, preliminary measurnments show that it is actually fast enough if we just optimize this to use a binary search instead of a linear scan.

My last PR(#4721) had to be rolled back(#4862) due to it overriding behavior many users expected. This PR solves a broader problem while trying to minimize surprises for the users. ### Problem description The underlying problem this PR tries to solve is the mismatch between [Rustc lint levels](https://doc.rust-lang.org/rustc/lints/levels.html) and [LSP diagnostic severity](https://microsoft.github.io/language-server-protocol/specification#diagnostic). Rustc currently doesn't have a lint level less severe than warning forcing the user to disable warnings if they think they get to noisy. LSP however provides two severitys below warning, information and hint. This allows editors like VSCode to provide more fine grained control over how prominently to show different diagnostics. Info severity shows a blue squiggly underline in code and can be filtered separately from errors and warnings in the problems panel. ![image](https://user-images.githubusercontent.com/13839236/84830640-0bb8d900-b02a-11ea-9e2f-0561b0e8f1ef.png) ![image](https://user-images.githubusercontent.com/13839236/84826931-ffca1880-b023-11ea-8080-5e5b91a6ac0d.png) Hint severity doesn't show up in the problems panel at all and only show three dots under the affected code or just faded text if the diagnostic also has the unnecessary tag. ![image](https://user-images.githubusercontent.com/13839236/84827165-55062a00-b024-11ea-8bd6-bdbf1217c4c5.png) ### Solution The solution provided by this PR allows the user to configure lists of of warnings to report as info severity and hint severity respectively. I purposefully only convert warnings and not errors as i believe it's a good idea to have the editor show the same severity as the compiler as much as possible. ![image](https://user-images.githubusercontent.com/13839236/84829609-50437500-b028-11ea-80a8-1bbd05680ba7.png) ### Open questions #### Discoverability How do we teach this to new and existing users? Should a section be added to the user manual? If so where and what should it say? #### Defaults Other languages such as TypeScript report unused code as hint by default. Should rust-analyzer similarly report some problems as hint/info by default?

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Anchoring to the SourceRoot wont' work if the path is absolute: #[path = "/tmp/foo.rs"] mod foo; Anchoring to a file will. However, we *should* anchor, instead of just producing an abs path. I can imagine a situation where, for example, rust-analyzer processes crates from different machines (or, for example, from in-memory git branch), where the same absolute path in different crates might refer to different files in the end!
