Templating

Yarte uses opening characters {{ and closing characters }} to parse the inside depending on the feature used. Most of the features are defined by Handlebars such as paths, comments, html, helpers and partials. Others such as adding rust code to a template, are obviously defined by Yarte. Each of these features have a symbol associated to it (# { R >) that is added after the opening characters, for example {{# used for helpers. If no symbol is added Yarte will interpret inside code as a valid rust expression.

Let's say we want to use the following template template.html

<h1> Hello, {{name}}! </h1>

Now we create a struct with the variable name

#![allow(unused_variables)]
fn main() {
#[derive(Template)]
#[template(path = "template.html")]
struct HelloTemplate<'a> {
    name: &'a str,
}
}

If we now render the template with "world" as value of name,

#![allow(unused_variables)]
fn main() {
HelloTemplate { 
    name: "world" 
}
.call().unwrap()
}
