Project history and usage

Erlang Language Platform, usually invoked as `elp`, is WhatsApp's Erlang semantic-analysis and editor-tooling project. It provides an LSP language server, a CLI, static-analysis infrastructure, and integration with eqWAlizer type checking.

Project history

The official repository was created in August 2023 and published a 0.1.0 GitHub release the same day. The README says ELP was designed at WhatsApp and inspired by rust-analyzer, with a scalable, fully incremental, IDE-first library for Erlang semantic analysis.

Adoption history

ELP exists because classic Erlang editor integrations and OTP tools are not always suited to incremental editing of incomplete code. The FAQ says ELP acts as a compiler front-end and language server, effectively superseding Erlang LS for its intended use case, while being architecturally closer to rust-analyzer than to a thin wrapper around existing OTP tools.

How it is used

Users install `elp` and point their editor's language-server client at it for go-to-definition, references, call hierarchy, diagnostics, linting, refactoring support, and type checking. Project configuration is handled with `.elp.toml` and lint settings with `.elp_lint.toml`.

Why package nerds care

ELP is notable for bringing the rust-analyzer style of incremental compiler front-end to Erlang packaging. For package maintainers, it is a modern Rust-built developer tool serving an older BEAM language ecosystem, so it sits at the intersection of Erlang, LSP, Rust build tooling, and editor distribution.

Timeline

2023: The GitHub repository was created.
2023: Version 0.1.0 was published on GitHub releases.
2020s: ELP documentation covers installation, editor setup, project configuration, and lint configuration for Erlang projects.
