history
Project history and usage
Starlark in Rust is Meta's Rust implementation of the Starlark configuration language, with a command-line binary that can run a REPL, evaluator, linter, and IDE-related tooling for standard Starlark.
Project history
The README states that facebook/starlark-rust is the canonical repository and that the project was started by Damien Martin-Guillerez. It also notes that version 0.4.0 changed ownership from Google to Meta.
The project exists in the ecosystem of Starlark implementations used by build systems. The README names Bazel, Buck, and Buck2 as Starlark users and says Buck2 depends on this library.
Adoption history
The input package facts show the project packaged for Homebrew and Nix, making the `starlark` binary available outside Rust's Cargo ecosystem.
Adoption is mostly developer-infrastructure adoption rather than end-user CLI adoption: most consumers embed the Rust library into build and configuration systems, while the packaged binary is useful for experiments, linting, and basic standard-Starlark evaluation.
How it is used
The README describes six components, including parser, evaluator, derive macros, map structures, LSP support, and `starlark_bin`, the binary exposed through the command line.
The README cautions that most Starlark embeddings add domain-specific functions and data types, so the packaged binary is most useful as a vanilla Starlark test bed or linter rather than a drop-in evaluator for every Starlark file from a large build system.
Why package nerds care
Package maintainers care about starlark-rust because Starlark is configuration language infrastructure. A standalone packaged interpreter/linter gives developers a way to test and inspect Starlark without installing a full build system.
The project is also notable because it bridges Rust packaging, language tooling, and build-system internals: the CLI is small enough to package, while the library is significant because Buck2 depends on it.
