Crate nbcl 

NBCL - Node Based Configuration Language

nbcl is a lightweight, declarative configuration DSL mainly designed for defining UI components and cloud infrastructure. The syntax is designed to be simple, and thus follows an HCL-inspired Blocky syntax but with the added benifits of modularity, scripting capabilities, and simplicity.

Example

use nbcl::NbclEngine;

fn main() {
    let code = r#"
        print("Hello, World")

        Object "language" {
            name = "nbcl"
            website = "nbcl-lang.github.io"
            playground = "nbcl-lang.github.io/playground"
            documnetation = "nbcl-lang.github.io/docs"
        }
    "#;

    let engine = NbclEngine::new();
    match engine.evaluate(code) {
        Ok(cfg) => println!("Resolved config: {:#?}", cfg),
        Err(e) => println!("Error: {}", e)
    }
}
