rpkl

Language bindings to Pkl for Rust.

Requires the pkl binary to be available on your path. You can install pkl for your os using the steps from their docs: https://pkl-lang.org/main/current/pkl-cli/index.html#installation

Usage

ip = "127.0.0.1"

database {
    username = "admin"
    password = "secret"
}

#[derive(Deserialize)]
struct Config {
    ip: String,
    database: Database,
}

#[derive(Deserialize)]
struct Database {
    username: String,
    password: String,
}

let config: Config = rpkl::from_config("./config.pkl")?;

Evaluator Options

You can pass options to the evaluator, such as properties, by using from_config_with_options.

let options = EvaluatorOptions::default()
.properties([("username", "root"), ("password", "password123")]);

let config: Config = rpkl::from_config_with_options("./config.pkl", Some(options))?;

Codegen

Mostly works, but still a WIP. If you want to try it out, you can enable the codegen feature.

let mut evaluator = rpkl::evaluator::Evaluator::new()?;
let pkl_mod = evaluator.evaluate_module(PathBuf::from("./config.pkl"))?;
pkl_mod.codegen()?;
