Mustache

Inspired by ctemplate and et, Mustache is a framework-agnostic way to render logic-free views.

As ctemplates says, "It emphasizes separating logic from presentation: it is impossible to embed application logic in this template language."

rust-mustache is a rust implementation of Mustache.

Documentation

The different Mustache tags are documented at mustache(5).

Install

Install it through Cargo!

[dependencies.rust-mustache]
git = "https://github.com/erickt/rust-mustache"

Then link it within your crate:

extern crate mustache;

Getting Started

extern crate mustache;
extern crate serialize;

use std::io;
use mustache::MapBuilder;

#[deriving(Encodable)]
struct Planet {
    name: ~str,
}

fn main() {
    // First the string needs to be compiled.
    let template = mustache::compile_str("hello {{name}}");

    // You can either use an encodable type to print "hello Mercury".
    let planet = Planet { name: "Mercury" };
    template.render(&mut io::stdout(), &planet).unwrap();
    println!("");

    // ... or you can use a builder to print "hello Venus".
    let data = MapBuilder::new()
        .insert_str("name", "Venus")
        .build();

    template.render_data(&mut io::stdout(), &data);
    println!("");

    // ... you can even use closures.
    let mut planets = vec!("Jupiter", "Mars", "Earth");

    let data = MapBuilder::new()
        .insert_fn("name", |_| {
            planets.pop().unwrap()
        })
        .build();

    // prints "hello Earth"
    template.render_data(&mut io::stdout(), &data);
    println!("");

    // prints "hello Mars"
    template.render_data(&mut io::stdout(), &data);
    println!("");

    // prints "hello Jupiter"
    template.render_data(&mut io::stdout(), &data);
    println!("");
}

Testing

Simply clone and run:

cargo test

If you want to run the test cases, you'll need the spec as well.

git submodule init
git submodule update
cargo test
