pklr

A pure Rust parser and evaluator for Apple's Pkl configuration language. No external binary or CLI required.

Features

• Lexer, parser, and evaluator written entirely in Rust
• Evaluates .pkl files to serde_json::Value
• Import analysis for cache invalidation
• Supports: objects, mappings, listings, local variables, spread (...), for/when generators, all primitive types

Usage

use pklr::eval_to_json;

let json = eval_to_json(std::path::Path::new("config.pkl"))?;
println!("{}", json);

Status

Early development. The goal is to cover the subset of Pkl used for configuration files (particularly hk configs), with broader language support added over time.
