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. ### Related projects - ELP is related to Erlang LS, rust-analyzer, Tree-sitter, Salsa, LSP clients, and eqWAlizer. ### Sources - - - - - ## Security Notes broad file, network, media, or database tool signal. generalized runtime or code generation signal. - **Geiger risk:** yellow / medium - broad file, network, media, or database tool signal - generalized runtime or code generation signal ## Configuration and credential file locations These source-backed paths show where this package keeps local settings or durable credentials.
