Rusty Domain Extensible Language

Crates.IO Documentation Build Nightly Build Donate using Liberapay

Domain specific language macros for Rust to generate xhtml. (pronounced "Rad Axle")

let my_int = 3;
let my_str = "asdf";
let my_vec = vec![true, false, true, true];

println!("{}",xhtml!(<ul>
   {{ for v in my_vec.iter() {{
      <li>{{my_int}}, {{my_str}}, {{v}}</li>
   }} }}
</ul>));

Modularized templating is encouraged through custom XML elements that implement the Display property. Foreign xhtml snippets or miscellaneous content can be inserted inline as long as it also implements the Display trait.

xtype!(<!MyList my_string:String my_int:u64>
   <!MyItem my_bool:bool/>
   <!MyOtherItem my_char:char/>
</MyList>);

xrender!(MyList, <ul>
  <li>{{ self.my_string }}</li>
  <li>{{ self.my_int }}</li>
  {{ for i in self.children.iter() {{
    {{ if let MyListChildren::MyItem(my_item) = i {{
      <li>MyItem: {{ my_item.my_bool }}</li>
    }} else if let MyListChildren::MyOtherItem(my_other_item) = i {{
      <li>MyOtherItem: {{ my_other_item.my_char }}</li>
    }} }}
  }} }}
</ul>);

Foreign syntaxes, like Javascript, may be quoted inline with cooked or raw strings.

xrender!(BarGraph,
  <script src="https://d3js.org/d3.v4.min.js"></script>
  <script>
    r#"var margin = {top: 20, right: 20, bottom: 30, left: 40},
           width = 960 - margin.left - margin.right,
           height = 500 - margin.top - margin.bottom;"#
    ...
  </script>
);
