This is a small library for template expansion. The syntax is based on
handlebars, but it only support expansion of variables. No #if or #each,
only {{ variable }}. If you need actual handlebars support consider the
handlebars crate.
It has no dependencies and is designed to have a very simple API.
rust
use handybars::{Context, Variable};
let ctx = Context::new().with_define("hello".parse().unwrap(), "world");
assert_eq!(ctx.render("hello {{ hello }}"), Ok("hello world".to_owned()));
You can also define objects
```rust
ctx.define("obj".parse().unwrap(), Object::new().withproperty("a", "value"));
asserteq!(ctx.render("object a: {{ obj.a }}"), Ok("object a: value".to_owned()));
You can even have nested objects
rust
ctx.define("obj".parse().unwrap(), Object::new().withproperty("b", Object::new().withproperty("c", "value"))); asserteq!(ctx.render("nested: {{ obj.b.c }}"), Ok("nested: value".toowned())); ```
Note that objects cannot be directly expanded:
rust
use handybars::{Context, Variable, Object, Error};
let ctx = Context::new().with_define("world".parse().unwrap(), Object::new().with_property("a", "p1"));
assert_eq!(ctx.render("{{world}}"), Err(Error::TriedToExpandObject(Variable::single("world"))));
