Crate neutron_engine 

Neutron Engine

A lightweight markup parser for the Neutron styling language (.nt). Provides fast, zero-dependency parsing of XML-like tags with inline style declarations.

Example

use neutron_engine::{parse_tag, parse_attributes, parse_style, normalize_decl, Attribute, StyleDecl};

let tag = r#"<Container style="b:#000; w:fill" id="Main">"#;
if let Some((name, attrs_text)) = parse_tag(tag) {
    println!("Tag: {}", name);

    let mut attrs = [Attribute { name: "", value: "" }; 12];
    let attr_count = parse_attributes(attrs_text, &mut attrs);

    for attr in &attrs[..attr_count] {
        if attr.name == "style" {
            let mut styles = [StyleDecl { name: "", value: "" }; 16];
            let style_count = parse_style(attr.value, &mut styles);

            for style in &styles[..style_count] {
                let prop = normalize_decl(*style);
                println!("Style: {:?}", prop);
            }
        }
    }
}
