{% Incrust %}

Incrust is a template engine inspired by Jinja2 and written in Rust.

NOTA BENE

This is a work in progress and (as may be assumed reasonably enough) may be highly unstable just yet.

The implementation is at a very early stage and the API is a subject of changes.

Installation

Incrust is available on crates.io and can be included in your Cargo enabled project like this:

[dependencies] incrust = "0.0"

Then include it in your code like this:

rust extern crate incrust;

Examples

All examples assume a prepared instance of Incrust. For ease of use hashmaps, we use the macro maplit

```rust

[macro_use]

extern crate maplit; extern crate incrust;

use incrust::{Incrust, Args, Var};

fn main() { let incrust = Incrust::new(); // ... } ```

Variables

rust let result = incrust.render_text("Hello, {{name}}!", &hashmap!{ "name" => Var::ex("World") }.unwrap(); assert_eq!(result, "Hello, World!");

Filters

rust let args: Args = hashmap!{ "text" => Var::ex("<Cats & Dogs>") }; let result = incrust.render_text("<h1>{{ text | e }}</h1>", &args).unwrap(); assert_eq!(result, "<h1>&lt;Cats &amp; Dogs&gt;</h1>");

Literals

rust assert_eq!("Braces: {{", incrust.render_text(r#"Braces: {{ "{{" }}"#, &hashmap!{}).unwrap()); assert_eq!("Pi: 3.1415926", incrust.render_text(r#"Pi: {{ 3.1415926 }}"#, &hashmap!{}).unwrap());

Expressions

```rust let args = hashmap!{ "what" => ex("Hello"), "who" => ex("World") }; asserteq!(r#"Say: "Hello, World!""#, incrust.rendertext(r#"Say: "{{ what + ", " + who }}!""#, args).unwrap());

let args = hashmap!{ "alpha" => ex(6isize), "omega" => ex(7f64) }; asserteq!("The answer is 42", incrust.rendertext(r#"The answer is {{ alpha * omega }}"#, args).unwrap()); ```

Comments

rust let tpl = incrust.parse("<p>Visible {# partially #} paragraph</p>").unwrap(); let result = incrust.render_parsed(tpl, &hashmap!{}).unwrap(); assert_eq!(result, "<p>Visible paragraph</p>");

Escaping

rust let tpl = "Example: {% raw %}{{ mustaches }}{% endraw %}"; let result = incrust.render_text(tpl, &hashmap!{}).unwrap(); assert_eq!(result, "Example: {{ mustaches }}");
