## Project history and usage

bacon-ls is a Rust language-server companion that publishes diagnostics from Bacon or directly from cargo. It is designed to supplement rust-analyzer, not replace it.

### Project history

The GitHub repository was created in May 2024. Its README frames the project around a specific pain point: rust-analyzer diagnostics can be slow on large Rust codebases, so bacon-ls exposes LSP diagnostic capabilities backed by Bacon or cargo.

By 2025-2026 the project had a steady GitHub release train from 0.6.0 to 0.29.0. The README documents an important evolution: the cargo backend became available in 0.23.0 and became the default in 0.26.0, making bacon-ls useful even without a separate background bacon process.

### Adoption history

Adoption is concentrated in editor and Rust-tooling circles. The README documents VS Code extension distribution through VSCE and Open VSX, Mason.nvim installation, manual cargo install, and Nix flakes. Homebrew packaging adds another general-purpose install path.

### How it is used

Users install bacon-ls alongside Rust tooling and configure an editor LSP client. It can publish diagnostics on save, open, close, rename, and manual triggers; run cargo check or clippy directly; or read Bacon's exported diagnostics file when Bacon is already running.

### Why package nerds care

bacon-ls is notable because it packages a focused LSP surface around diagnostics only. For Rust developers with large workspaces, it is a small composable alternative to making rust-analyzer do every job, and its packaging across cargo, editor registries, Nix, Mason, and Homebrew reflects modern developer-tool distribution.
