Allow to extend mustache

jcubic commented 11 years ago

Maybe it's good idea to allow extension of mustache wihout modifing library or Mustache class so user can put {{@foo}} or {{%foo}} and those will execute user defined function

$mustache = Mustache_Engine(array(
    'modifiers' => array(
       '%' => function($tag) {
            return file_get_contents($tag);
       }
    )
));

or

$mustache = Mustache_Engine(array(
    'tags_extension' => function($modifier, $tag_name, $leading, $trailing) {
        switch($modifier) {
            case '%':  return file_get_contents($tag_name);
        }         
    }
));

and user will be able to put

<html>
   <body>
      <h1>My robots.txt</h1>
      <pre>{{%robots.txt}}</pre>
   </body>
</html>

and those modifiers will be check in _renderTag method after all of tags or before so they can be overwriten.

What's wrong / missing with higher-order sections? https://github.com/bobthecow/mustache.php/wiki/Magic-Methods#__invoke You could pass such callbacks to the Mustache renderer as data array. Another option is defining reusable components as partials, and could then be included like {{>robots.txt}}

@mxhCodes sorry it was 9 years ago when the issue was created. I don't have the use case for the requirement. No one replied for 9 years, so I think that the project is dead.

I think it was for this project Aiki Framework, where I needed my own markup DSL.

Ha! Sorry. It's not dead, I just missed this issue somehow when it was opened 😞

In general the mustache-y answer for this sort of thing would be higher order sections, filters, or a smarter view model.
