+Askama

+
+Askama implements a template rendering engine based on Jinja.
+It generates Rust code from your templates at compile time
+based on a user-defined ``struct`` to hold the template's context.
+See below for an example.
+
+Currently implemented features:
+
+* Generates fully type-safe Rust code from your templates
+* Template inheritance
+* Basic loops and if/else if/else statements
+* Whitespace suppressing with '-' markers
+* Some built-in filters
+
+Askama is in heavy development, so it currently has some limitations:
+
+* Only a small subset of the intended expressions are supported in templates
+* Only a small number of built-in template filters have been implemented
+* User-defined template filters are not supported yet
+* Not a lot of documentation has been written
+
+All feedback welcome. Feel free to file bugs, requests for documentation and
+any other feedback to the `issue tracker`_ or `tweet me`_.

+
+
+How to get started
+------------------
+
+First, add the following to your crate's ``Cargo.toml``:
+
+.. code-block::
+
+ // in section [package]
+ build = "build.rs"
+
+ // in section [dependencies]
+ askama = "0.1"
+ askama_derive = "0.1"
+
+ // in section [build-dependencies]
+ askama = "0.1"
+
+Custom derive macros can not be exported together with other items,
+so you have to depend on a separate crate for it.
+Because Askama will generate Rust code from your template files,
+the crate will need to be recompiled when your templates change.
+This is supported with a build script, ``build.rs``,
+which needs askama as a build dependency:
+
+.. code-block:: rust
+
+ extern crate askama;
+
+ fn main() {
+ askama::rerun_if_templates_changed();
+ }
+
+Now create a directory called ``templates`` in your crate root.
+In it, create a file called ``hello.html``, containing the following:
+
+.. code-block:: jinja
+
+ Hello, {{ name }}!
+
+In any Rust file inside your crate, add the following:
+
+.. code-block:: rust
+
+ #[macro_use]
+ extern crate askama_derive; // for the custom derive implementation
+ extern crate askama; // for the Template trait
+
+ use askama::Template; // bring trait in scope
+
+ #[derive(Template)] // this will generate the code...
+ #[template(path = "hello.html")] // using the template in this path, relative
+ // to the templates dir in the crate root
+ struct HelloTemplate<'a> { // the name of the struct can be anything
+ name: &'a str, // the field name should match the variable name
+ // in your template
+ }
+
+ fn main() {
+ let hello = HelloTemplate { name: "world" }; // instantiate your struct
+ println!("{}", hello.render()); // then render it.
+ }
+
+Review the `test cases`_ for more examples.
