Thanks to [@blaenk](https://github.com/blaenk)'s patch,
handlebars-rust now compiles on nightly, beta and 1.0 channel.
## Why Handlebars?
For information about handlebars, you will go to [handlebars.js](http://handlebarsjs.com).
It's my favorite templating tool by far. I used it in
[Delicious.com](https://delicious.com) as javascript-side template in
2013. Also I maintained a Clojure wrapper for Handlebars.java,
[hbs](http://github.com/sunng87/hbs). And you may notice the
close relationship between Ember.js and Rust community, handlebars is
the default templating language of Ember.js framework, which powers
[crates.io](http://crates.io).
Reasons I prefer Handlebars:
* Never ruin your Rust with HTML
* Never ruin your HTML with Rust
* Templating without a reuse mechanism is shit
* Templating without customization is nothing but shit
Handlebars provides:
* Separation of Rust and HTML
* A few control structures makes templating easier
* Few control structures stops you to put logic into templates
* Template reuse with include(`>`), `partial` and `block`
* Customize template behavior with **helper**s
Limitations:
* As a static typed language, it's a little verbose to use handlebars
* You will have to make your data `ToJson`-able, so we can render
it. If you are on nightly channel, we have [a syntax extension](https://github.com/sunng87/tojson_macros) to generate default `ToJson` implementation for you.
## Usage
Check examples in the source. The example shows you how to:
* Create a `Handlebars` and register the template from files
* Create a custom Helper with closure or struct implementing `HelperDef`, and register it
* Render something
Run `cargo run --example render` to see results.
(or `RUST_LOG=INFO cargo run --example render`) for logging output.
## Handlebars-js features supported in Handlebars-rust
* Expression / Block Helpers
* Built-in helpers
* Customizing helper
* Parameter and hashes for helper
* Partials, include
* Omitting whitespace with `~`
* Subexpression `{{(foo bar)}}`
Feel free to report an issue if you find something broken. We aren't
going to implement all features of handlebars-js, but we should have a
workaround for cases we don't support.
## Handlebars for Iron
I have started another project
[handlebars-iron](https://github.com/sunng87/handlebars-iron) for
the Iron web framework.
