Example Blade extension from docs does not work

[carcinocron]

I already posted this here a month ago: http://laravel.io/forum/05-20-2014-example-blade-extension-from-docs-does-not-work

This triggers a fatal error

Blade::extend(function($view, $compiler)
{
    $pattern = $compiler->createMatcher('datetime');

    return preg_replace($pattern, '$1<?php echo $2->format('m/d/Y H:i'); ?>', $view);
});

syntax error, unexpected 'm' (T_STRING)

Obviously fixed by changing:

'$1<?php echo $2->format('m/d/Y H:i'); ?>'

to

'$1<?php echo $2->format(\'m/d/Y H:i\'); ?>'

But then:

<?php $c = Carbon::now(); ?>

<?php echo ($c)->format('m/d/Y H:i'); ?>

Symfony \ Component \ Debug \ Exception \ FatalErrorException
syntax error, unexpected '->' (T_OBJECT_OPERATOR), expecting ',' or ';'

You can put the code directly to the blade files and it would work.

In your example you should instantiate the class by its full name:

<?php
            $c = new Carbon\Carbon();
            echo $c->format('m/d/Y H:i');
?>

Below is my extension to the blade regarding the php which works fine:

<?php

Blade::extend(function ($view) {

    return preg_replace(
                         '/{{php((.|\s)*?)}}/', 
                         '<?php $1 ?>', $view
                       );

});

I just tried:

• putting Blade::extend in the view itself with <?php ?>
• using \Carbon\Carbon instead of Carbon
• using @datetime(\Carbon\Carbon::now()) instead of @datetime($c)

Still produced the same error.

You probably shouln't be using createMatcher in this case. Write your own regular expression for it.

I don't mind writing my own Regex, but are you going to leave the docs with non-working code? http://laravel.com/docs/templates#extending-blade

Could you send a pull request to github.com/laravel/docs addressing the issue?
