A Language Server Protocol client implementation for JetBrains IDEs.
Some language servers require or benefit from special support by clients. LSP-IDEA comes bundled with extensive rust-analyzer integration and makes it easy for developers to implement new integrations on top of the existing infrastructure (via extension points).
- One-click installation of rust-analyzer executable (on Windows)
- Complete configuration UI
- Support for one-click running code through code lenses (e.g. green "Run" arrow next to main method)
- rust-analyzer-specific extensions to LSP
- Any executable that supports stdin/stdout communication can be used as a language server
- Syntax highlighting based on Semantic Tokens
- Code completion
- Go to definition/declaration
- Go to class/go to symbol
- Reformat file
- Find references
- Rename
- Extract variable/constant/function
- Expand/contract selection ((Shift+)Ctrl+W)
- Structure View (Ctrl+F12)
- Code Lenses
- Highlight usages
- Code Folding
- Diagnostics
- Quickfixes, code actions
- Move Item up/down
- Join Lines
- On Enter
- Progress reporting
One of LSP-IDEA's design goals is debuggability. To that end, it features multiple tool windows for inspecting
- JSON-RPC messages, including their contents and stacktraces;
- the language server's stderr;
- semantic tokens as decoded by LSP-IDEA, including highlighting selected tokens.
