LSP Features

The server currently exposes a compact but useful LSP surface focused on navigation, diagnostics, and conservative semantic analysis.

Core Lifecycle

Supported protocol methods include:

• initialize

• initialized

• shutdown

• exit

• textDocument/didOpen

• textDocument/didChange

• textDocument/didClose

Navigation And Intelligence

The current server supports:

• textDocument/declaration

• textDocument/definition

• textDocument/implementation

• textDocument/references

• textDocument/rename

• textDocument/prepareRename when the client advertises rename prepare support

• textDocument/hover

• textDocument/documentSymbol

• workspace/symbol

• textDocument/documentHighlight

• textDocument/completion

• textDocument/signatureHelp

• textDocument/foldingRange

• textDocument/documentLink

Completion is triggered by $, :, and -. Signature help is triggered by a space or tab after the command name and earlier arguments.

Semantic Output

The server publishes diagnostics and semantic tokens for open documents:

• textDocument/publishDiagnostics on open, change, and close

• textDocument/semanticTokens/full

• textDocument/semanticTokens/full/delta

Implementation Limits

The current protocol implementation still has some notable limits:

• text synchronization is full-document only

• position handling does not yet negotiate a custom positionEncoding

• automatic workspace discovery is limited; unopened files are indexed conservatively through package inference rather than full file watching

• code actions, formatting, code lens, and inlay hints are not implemented
