history

Project history and usage

just-lsp is a Rust language-server implementation for `just` files. It brings editor features such as completion, hover documentation, go-to-definition, diagnostics, rename, references, semantic highlighting, folding, formatting, and code actions to `justfile` workflows.

Project history

The just-lsp repository was created on 2022-02-12 by Liam Scalzulli. It appeared after `just` had become a popular Make-like command runner and after Language Server Protocol tooling had become the normal way to add editor intelligence without writing editor-specific plugins.

The project is intentionally narrow: it tracks the syntax and builtin surface of `just` and exposes it through the Language Server Protocol. The `just` manual includes a language-server page that points users to just-lsp for go-to-definition, inline diagnostics, and code completion.

Adoption history

just-lsp adoption follows editor adoption of `justfile` automation. Its README documents installation through Cargo, Homebrew, Arch Linux, Mason for Neovim, and prebuilt binaries for Linux, macOS, and Windows. The input package metadata also shows packaging in Alpine, Homebrew, Nix, and Arch.

The official repository metadata showed more than 300 GitHub stars on 2026-07-01, which is modest but meaningful for a language server dedicated to one task-runner file format.

How it is used

Users install `just-lsp`, configure their editor's LSP client for `justfile` files, and get structured diagnostics and navigation while editing recipes. It is especially useful in repositories where the justfile has grown beyond a small list of shell snippets.

Because formatting delegates to `just --fmt --unstable`, just-lsp sits beside the `just` binary rather than replacing its parser and formatter as the authority for the language.

Why package nerds care

just-lsp is a small sign of `just` becoming infrastructure rather than a personal helper binary. Once a file format gets a language server, package maintainers and editor users start treating it as a language with syntax, diagnostics, and tooling expectations.

For package nerds, it is also an example of the LSP pattern spreading from programming languages to configuration and automation files.

  • The Language Server Protocol is the editor protocol just-lsp implements.
  • Mason is a Neovim package manager that the just-lsp README documents as an installation path.
  • tree-sitter grammar work around justfiles is adjacent because syntax awareness is central to editor tooling.

Recommended review

Before unattended agent use, check whether the tool reads plaintext credentials, writes remote state, publishes artifacts, or shells out to plugins.
