A Rust implementation of the Starlark language, a deterministic Python3-inspired configuration language used by build systems like Bazel and Buck2. It provides a library with garbage-collected values, Rust interoperability, a linter, LSP and DAP support.
Use cases
- embed a Starlark interpreter in a Rust application
- evaluate Starlark build configuration files
- lint Starlark code for issues
- build a custom configuration language for my tool
- add IDE support for Starlark via LSP
- debug Starlark scripts with DAP
When to choose
- you need to evaluate Starlark from Rust
- you're building tooling around Bazel or Buck2 build files
- you want a deterministic, sandboxed configuration language embedded in Rust
When to avoid
- you need a general-purpose scripting language
- you require a stable API across releases
- you're working in a non-Rust codebase (consider starlark-go or the Java implementation)
