Language Server Protocol
Overview
An implementation of the Language Server Protocol for R. The Language Server protocol is used by an editor client to integrate features like auto completion. See https://microsoft.github.io/language-server-protocol/ for details.
- Run full-document, range, and multiple-range formatting in a lazy, cancellable background worker so other editor requests remain responsive during formatting (#764, #251).
- Stabilize diagnostics for Quarto and R Markdown documents by preserving source-specific settings, custom suppression markers, and exclusions when linting extracted code, while normalizing paths on Windows (#763, #726).
- Clear published diagnostics and cancel queued or running lint tasks when diagnostics are disabled (#763).
- Strictly enforce mutual exclusivity of
resultanderrorin JSON-RPC responses per the JSON-RPC 2.0 specification, preventing strict clients like Neovim from disconnecting on errors (#768, #766). - Prevent undefined behavior in
reference_resolve_local_c()by guardingqsortand avoiding zero-length allocations when definitions or occurrences are empty (#767).

- Speed up test-coverage workflow by utilizing 4 CPUs, path filtering, and 4-way balanced test sharding (#769).
**Closed issues:**
- Ensure error and result are mutually exclusive in JSON-RPC responses (#766)
- Quarto / R Markdown / new file buffers ignoring nested
.lintrconfig and diagnostics not clearing when disabled (#726) - Non-blocking formatting: run explicit formatting in background (#251)
**Merged pull requests:**
- Speed up test-coverage workflow with 4 CPUs, sharding, and path filtering (#769)
- Ensure error and result are mutually exclusive in JSON-RPC responses (#768)
- Avoid passing null or zero-length buffers to qsort in reference resolution (#767)
- Run explicit formatting in the background (#764)
- Stabilize diagnostics (#763)
