Anyway, this post isn't about how awesome Craft is (which it is), it's about a piece of auspiciously missing documents: how to create your own Twig filter inside of craft!

Whether you're a developer or designer, manager or assistant, PyroCMS helps you quickly design, build and manage your website.

Bolt is an open source Content Management Tool, which strives to be as simple and straightforward as possible. It is quick to set up, easy to configure, uses elegant templates, and above all: It’s a joy to use.

Presenting a faster, easier and more powerful way to build themes. Because WordPress is awesome, but the loop isn't.

SuperSort provides a Twig filter sorting an array of objects, either using one of PHP's built-in methods to sort the actual objects, or using a custom sort method to arrange the array based on the rendered results of running each object through a Twig object template.

Using SuperSort's custom "sort as" methods, you can sort an array of elements by any accessible object value — including values from Matrix blocks, related elements, math calculations, etc.

Timber helps you create fully-customized WordPress themes faster with more sustainable code. With Timber, you write your HTML using the Twig Template Engine separate from your PHP files.

Why Twig documentation recommends to use extending rather than including? Symfony 2 documentation says because "In Symfony2, we like to think about this problem differently: a template can be decorated by another one." but nothing more. It's just author's whim or something more? Thanks for help.

Pack up your content, markup, and style. Leave the database behind.

Craft is a content management system (CMS) that’s laser-focused on doing one thing really, really well: managing content. And since content comes in all shapes and sizes, we’ve built Craft to be as flexible as possible, without compromising on the ease of use for content authors.

Django, Ruby on Rails, Node.js, Laravel, Drupal—what do these platforms have that WordPress lacks? A template language.

This example works on WP 3.5.1. Much simpler and simply works. This is an updated version of Otto's tutorial.

This package installs the (usually) latest PHP 5.5/5.4/5.3 on OS X 10.6 (aka Snow Leopard), OS X 10.7 (aka Lion) and OS X 10.8 (aka Mountain Lion) and OS X 10.9 (aka Mavericks) in /usr/local/php5. It installs many useful extensions (see below) and ini-settings and is what we at Liip and Local.ch use for our development. It's especially suited for Symfony 2 development. It also provides a decent php.ini with all settings configured according to "Best Practices".
