Stencil

Stencil is a simple and powerful template language for Swift. It provides a syntax similar to Django and Mustache. If you're familiar with these, you will feel right at home with Stencil.

Example

There are {{ articles.count }} articles.

<ul>
  {% for article in articles %}
    <li>{{ article.title }} by {{ article.author }}</li>
  {% endfor %}
</ul>

import Stencil

struct Article {
  let title: String
  let author: String
}

let context = [
  "articles": [
    Article(title: "Migrating from OCUnit to XCTest", author: "Kyle Fuller"),
    Article(title: "Memory Management with ARC", author: "Kyle Fuller"),
  ]
]

let environment = Environment(loader: FileSystemLoader(paths: ["templates/"]))
let rendered = try environment.renderTemplate(name: "article_list.html", context: context)

print(rendered)

Philosophy

Stencil follows the same philosophy of Django:

If you have a background in programming, or if you’re used to languages which mix programming code directly into HTML, you’ll want to bear in mind that the Django template system is not simply Python embedded into HTML. This is by design: the template system is meant to express presentation, not program logic.
