Phly\Mustache is a Mustache (http://mustache.github.com) implementation written

for PHP 5.3+. It conforms to the principles of mustache, and allows for

extension of the format via pragmas.

Architecture

============



Phly\Mustache consists of five primary classes:



- Lexer: tokenizes mustache syntax.

- Renderer: renders a list of tokens, using substitions provided via a view.

- Pragma: interface for pragmas, which may modify how tokens are handled

- Resolver: resolves a template name to mustache syntax or tokens.

- Mustache: facade/gateway class. Tokenizes and renders templates, caches

  tokens, provides partial aliasing, and acts as primary interface for

  end-users.



Usage

=====

Usage is fairly straightforward:



    include '/path/to/library/Phly/Mustache/_autoload.php';

    use Phly\Mustache\Mustache;



    $mustache = new Mustache();

    echo $mustache->render('some-template', $view);



By default, phly_mustache will look under the current directory for templates

ending with '.mustache'; you can create a stack of directories to search by

using the setTemplatePath() method:



    $mustache->setTemplatePath($path1)

             ->setTemplatePath($path2);



In the above, it will search first $path2, then $path1 to resolve the template.



You may also change the suffix it will use to resolve templates:



    $mustache->setSuffix('html'); // use '.html' as the suffix



If your templates use pragmas, you must first add pragma handlers to the

renderer. This can be done as follows:



    use Phly\Mustache\Pragma\ImplicitIterator as ImplicitIteratorPragma;

    $mustache->getRenderer()->addPragma(new ImplicitIteratorPragma());

    $mustache->render('template-with-pragma', $view);



Views can be either associative arrays or objects. For objects, any public

member, either a property or a method, may be referenced in your template. As an

example:



    class View

    {

        public $first_name = 'Matthew';



        public $last_name  = "Weier O'Phinney";



        public function full_name()

        {

            return $this->first_name . ' ' . $this->last_name;

        }

    }



Any property (or array key) may also refer to a valid callback; in such cases,

the return value of the callback will be used.



    $view = new \stdClass;

    $view->first_name = 'Matthew';

    $view->last_name  = "Weier O'Phinney";

    $view->full_name  = function() use ($view) {

        return $view->first_name . ' ' . $view->last_name;

    };



The following sections detail unique and/or advanced features of phly_mustache.



Autoloading

===========

phly_mustache follows the PSR-0 standard for class naming conventions, meaning

any PSR-0-compliant class loader will work. To simplify things out of the box,

the component contains an "\_autoload.php" file which will register an autoloader

for the phly_mustache component with spl_autoload. You can simply include that

file, and start using phly_mustache.



Higher Order Sections

=====================

"Higher order sections" refer to callbacks that return callbacks. As an example,

consider the following template:



    {{#bolder}}Hi {{name}}.{{/bolder}}



and the following view:

    

    $view = new \stdClass;

    $view->name = 'Tater';

    $view->bolder = function() {

        return function($text, $renderer) {

            return '' . $renderer($text) . '';

        };

    };



In this case, the contents of the section, "Hi {{name}}." will be passed as the

first argument to the section, and a callback capable of rendering will be

passed as the second (this is basically a closure that curries in the current

Renderer object and calls the appropriate method). This allows you to re-use a

given "section" in order to create re-usable capabilities; think of them like

"view helpers" in systems like Zend_View, Solar_View, Savant, etc.



Partials

========

Partials are a basic form of inclusion within Mustache; anytime you find you

have re-usable bits of templates, move them into a partial, and refer to the

partial from the parent template.



Typically, you will only reference partials within your templates, using

standard syntax:



    {{>partial-name}}



However, you may optionally pass a list of partials when rendering. When you do

so, the list should be a set of alias/template pairs:



    $mustache->render($template, array(), array(

        'winnings' => 'user-winnings',

    ));



In the above example, 'winnings' refers to the template

"user-winnings.mustache". Thus, within the $template being rendered, you may

refer to the following partial:



    {{>winnings}}



and it will resolve to the appropriate aliased template.



A few things to remember when using partials:



 - The parent template may change tag delimiters, but if you want to use the

   same delimiters in your partial, you will need to make the same declaration.

 - The parent template may utilize one or more pragmas, but those declarations

   will not perist to the partial; if you want those pragmas, you must reference

   them in your partial.



Basically, partials render in their own scope. If you remember that one rule,

you should have no problems.



Hierarchical Views and Placeholders

===================================



(Available in versions 1.1.0 and up).



Placeholders are basically unnamed sections, and are denoted by the combination

of `{{$name}}` and `{{/name}}`. When encountered by the renderer, any mustache

content within will be rendered as normal mustache content.



Placeholders are primarily of use with the concept of hierarchical views. These

are denoted by the combination of `{{

    {{$title}}Default title{{/title}}

    

    


    {{$content}}Default content of the page{{/content}}

    


    

    

    


    Default content of the page

    


    

        {{content}}

    

    

        Hello, Matthew!
