## Project history and usage

Erlang LS is an Erlang language server for editors and IDEs, packaged by Homebrew as erlang_ls and implemented as an Erlang server for Microsoft's Language Server Protocol.

### Project history

The project documentation describes Erlang LS as a language server that provides Erlang language features such as auto-complete and go-to-definition through the Language Server Protocol. The README later documented support for LSP 3.17 and OTP 24 through OTP 27.

### Adoption history

Erlang LS fit the broader editor shift toward LSP-based tooling: one server process could support multiple editor clients. Its README points users to GitHub issues and the Erlanger Slack channel for project participation, while the README warns that the project is unmaintained and recommends the Erlang Language Platform language server instead.

### How it is used

Users run the erlang_ls escript from an editor integration, usually over TCP or stdio. Project-specific configuration lives in PROJECT_ROOT/erlang_ls.config, and global defaults can be stored in the user config directory for Linux, macOS, or Windows.

### Why package nerds care

The Homebrew formula is useful for editor setup because it installs a single erlang_ls executable independent of a particular editor plugin. Its unmaintained status is important package metadata because new users may prefer ELP while existing users may still need erlang_ls for older editor workflows.

### Timeline

- 2024-10-02: Erlang LS 1.0.0 was published on GitHub Releases.
- 2024-10-09: Erlang LS 1.1.0 followed as a later GitHub release.
- README status note: the project is marked unmaintained and recommends Erlang Language Platform.

### Related projects

- Erlang LS depends on Erlang/OTP and rebar3 for building and operation.
- The README recommends Erlang Language Platform as the successor language server for new users.
