custom helper not doing its job

Thanks HosipLan,

with a reference to your previous example:https://forum.nette.org/…e-a-template#… it works only on default macros:

<?php
class CustomMacros extends Nette\Latte\Macros\MacroSet
{
	public static function parseString($string)
        {
            $latte = new Nette\Latte\Engine;
            //$latte->parser = new Nette\Latte\Parser;
            $template = new Nette\Templating\Template;
            $template->registerHelper('big', callback('strtoupper'));
            CustomMacros::install($latte->parser);
            $template->setSource($string);
            $template->registerFilter($latte);
            return = (string)$template;
       }

// -------------

$string = CustomMacros::parseString('{var $check="var"} {$check|big} {box|big}box{/box}');
echo $string;

// -------------
?>

This prints “VAR <div>box</div>” instead of expected “VAR <div>BOX</div>”

Hello,

I have installed {box}{/box} as per previous advice from HosipLan. It prints the div around the string, it just does not apply macro on it.

<?php
$string = CustomMacros::parseString('{var $check="var"} {$check|nonExistentMacro} {box |big}box{/box}');
?>

the above screams: Call to undefined method: Nette\Templating\Template::nonExistentMacro()
which is OK.

<?php
$string = CustomMacros::parseString('{var $check="var"} {$check|big} {box |nonExistentMacro}box{/box}');
?>

This one prints “VAR <div>box</div>”, no error.

If I add default handlers:

<?php
        public static function parseString($string)
        {
            $latte = new Nette\Latte\Engine;
            //$latte->parser = new Nette\Latte\Parser;
            $template = new Nette\Templating\Template;
            $template->registerHelper('big', callback('strtoupper'));
	    $template->registerHelperLoader('Nette\Templating\DefaultHelpers::loader'); // NOTE THIS
            CustomMacros::install($latte->parser);
            $template->setSource($string);
            $template->registerFilter($latte);
            return = (string)$template;
       }
// -----------
$string = CustomMacros::parseString('{var $check="var"} {$check|upper} {box |upper}box{/box}');

?>

It applies default helpers only on default macros: “VAR <div>box</div>”.
It never applies helper on custom macro even it does apply macro (the div here).
What's wrong with me?

Ok, thanks. This was quite simplified example and the solution does not solve my aim. So to be a bit more specific, this is more like it:

Blah blah {user pepa|email} blah.

The macro should get class::user($attribute,$name = false) or class class::$user[$attribute] or something similar – so that helper is always trying to get a key of an array… anything.

I have touched this topic here already, I just hope I will be able to do it with Nette parsers.
My problem is, that anytime I try to apply helper on custom macro in template outside a presenter and then cast to a string it does not work or error…
