## Project history and usage

Expert is the official Language Server Protocol implementation for Elixir. It provides editor-facing language intelligence and ships as a standalone executable.

### Project history

The official GitHub repository was created in 2024 under expert-lsp/expert and describes Expert as the official Elixir language server implementation. Its documentation presents installation via editor extensions, Homebrew, Mason, Nix, Mise, GitHub releases, and source builds.

### Adoption history

Expert reached the 0.1.0 release line in March 2026 after several release candidates. The official installation page includes Homebrew as a supported package-manager path, and the supplied package metadata confirms a Homebrew formula.

### How it is used

Expert is typically installed on PATH and configured through an editor's LSP client. The official README notes that clients should pass --stdio when the editor does not do so automatically, and the configuration page documents settings such as workspaceSymbols.minQueryLength.

### Why package nerds care

Expert is interesting to package maintainers because language servers are editor infrastructure: users expect repeatable binary installs, architecture-specific releases, and integration through Homebrew, Nix, Mason, Mise, and editor-managed downloads.
