Nette 2.2: registering filters

Hi,
I have been trying for several hours to understand the new way Latte is
integrated in Nette 2.2 but I got completely lost in the docs, APIs and
sources. Many topics seem to be quite related to my problem but I haven't found
an answer.
I would like to apply my own filter on the template before Latte is applied.
In Nette 2.1, I used to redefine the templatePrepareFilters() in
my BasePresenter like this:
public function templatePrepareFilters($template)
{
$template->registerFilter(new \MyExt\MyCustomFilter());
$latte = new Nette\Latte\Engine;
$template->registerFilter($latte);
}Now in 2.2, the registerFilter is deprecated. What's the
recommended replacement?
Thanks for any hint!

MartyIX: New Latte filter is the synonym for
the old Latte helper. So helpers = filters now.
robix: Old template filters are not supported/implemented in the alone Latte. You can check the current deprecated behaviour and copy it by your own. Maybe someone else give you a better hint :(

Thanks for reply. I have been looking into the code and it seems that in
2.2.1, Latte is directly bound to the template used in the presenter. I.e. for
using something different, I have to create another Template class
and change the rendering. However, it seems that Latte reads the template source
by itself now so I can see no space for integrating some pre-processing
filter :-(

You can use for loading StringLoader, see https://github.com/…oEscape.phpt#L14

That was it! Now it's solved. I created my own Loader that implements the
pre-filtering and I register it in startup() of my
BasePresenter:
public function startup()
{
parent::startup();
$this->template->getLatte()->setLoader(new \My\OwnLoader($this));
}Or is there any more suitable place to set the loader?
Many thanks!

You can do it in startup(), little bit better is to use
createTemplate():
protected function createTemplate()
{
$template = parent::createTemplate();
$template->getLatte()->setLoader(new My\OwnLoader($this));
return $template;
}Because this is very new part of Nette and default Loader is under development, inherit your loader from the original one (for forward compatibility):
class OwnLoader extends Nette\Bridges\ApplicationLatte\Loader
{
public function getContent($file)
{
$content = parent::getContent($file);
// modify $content
return $content;
}
}
