What is pklr?

pklr is a pure Rust parser and evaluator for Apple's Pkl configuration language, turning .pkl files into serde_json::Value without needing the official Pkl CLI or binaries. It handles imports, amends, string interpolation, lambdas, and higher-order methods, outputting clean JSON for Rust apps. Think of it as embedding Pkl config processing directly into your Rust tools, like a pure rust database or pure rust gui for configs.

Why is it gaining traction?

Unlike the Java-based Pkl CLI, pklr runs natively in Rust binaries with zero external deps, making it ideal for cross-platform tools—no JVM headaches. Rich miette errors pinpoint issues fast, and async HTTP support via reqwest pulls remote configs seamlessly. Devs grab it for ditching heavy runtimes, akin to pure data or pure hud github projects that prioritize lightweight purity.

Who should use this?

Rust CLI authors building config loaders, like those replacing pkl eval in CI pipelines or embedding Pkl in servers. Backend teams parsing user-supplied .pkl for dynamic JSON output, or ops engineers analyzing imports without full eval. Skip if you're not in Rust or need every Pkl edge case today.

Verdict

At 11 stars and 1.0% credibility, pklr is early (v0.4.0) with solid README usage examples but light tests—experiment in prototypes, not prod yet. Pair it with pure storage patterns for lean config stacks; watch for maturity as Pkl grows.
