Commit: commit:2c8f136b162e795a32e7dff2d0456c323377575d[]
Release: release:2020-03-02[]

New Features

  • pr:3159[], pr:3321[], pr:3322[] switch syntax highlighting implementation to use the new proposed semantic token LSP/VS Code API.To try this out:

    • install vscode plugin from source (using cargo xtask install --client-code)

    • set "rust-analyzer.highlighting.semanticTokens": true, in settings,

    • install the recent VS Code Insiders

    • run code as code-insiders --enable-proposed-api matklad.rust-analyzer (handy bash wrapper)

  • pr:3362[] remove ctrl+r default keybinding for running tests & binaries, to avoid conflict with a build-in keybinding. You might want to assign shortcut for this action, it is a productivity booster!

  • pr:3349[] rust-analyzer now highlights code in rust-analyzer’s own tests as rust:

  • pr:3294[] when joining lines, unwrap single-statement blocks if possible.

  • pr:3285[] structural search replace now correctly ignores whitespace differences.

  • pr:3357[] change visibility assist now works with consts:

  • pr:3355[] add completion & docs for featureFlag configuration in VS Code extension.

  • pr:3309[] look for Cargo.toml not only in the root and parent directory, but also among one-level child directories.

  • pr:3387[] type inference for slice patterns.

  • pr:3397[] add minimal metatdata to VS Code extension.

Fixes

  • pr:3314[], pr:3325[], pr:3350[], pr:3366[] fix a lot of range-mapping bugs for recursive macro invocations.

  • pr:3308[] fix conflict for Enter key with VS Code vim extension. If rust-analyzer’s custom on enter behavior causes you trouble, you can disable it by removing the corresponding shortcut from the settings.

  • pr:3364[] correctly handle unions in IDEs.

  • pr:3367[] finally fix highlighting and name goto definition for constants in patterns, like None.

  • pr:3376[] fix a common false-positive type mismatch.

  • pr:3380[] use unsizing in method resolution & autoderef for indexing.

  • pr:3384[] fix name resolution for paths with repeated super segments.

Internal Improvements

  • pr:3222[] redo the interface between "compiler" and "IDE". IDE no longer needs to explicitly track the file a particular bit of syntax tree originated from.

  • pr:3296[] bump TypeScript version.

  • pr:3299[] more type safe way to deal with custom LSP extensions.

  • pr:3298[] update chalk.

  • pr:3316[] remove code duplication in assists tests.

  • pr:3324[], pr:3335[], pr:3344[], pr:3346[] refactor syntax highlighting infrastructure to be more future proof and robust.

  • pr:3329[], pr:3330[] run cargo audit and npm audit on CI.

  • pr:3337[] remove unused dependencies.

  • pr:3340[] gate CI on eslint.

  • pr:3351[] better API for working with string literals.

  • pr:3360[] fix parsing of attributes in let statements.

  • pr:3370[] extract code for adding a new use item to a separate module.

  • pr:3374[] cleanup API for constructing syntax trees for paths.

  • pr:3375[] cleanup API for editing syntax trees.

  • pr:3377[] simplify API for getting semantic definitions from syntax trees.
