Type System

The declared types are informative and Latte does not check them at this time.

How to start using types? Create a template class, eg CatalogTemplateParameters, representing the passed parameters:

class CatalogTemplateParameters
{
	public function __construct(
		public string $langs,
		/** @var ProductEntity[] */
		public array $products,
		public Address $address,
	) {}
}

$latte->render('template.latte', new CatalogTemplateParameters(
	address: $userAddress,
	lang: $settings->getLanguage(),
	products: $entityManager->getRepository('Product')->findAll(),
));

Then insert the {templateType} tag with the full class name (including the namespace) at the beginning of the template. This defines that there are be variables $langs and $products in the template including the corresponding types. You can also specify the types of local variables using tags {var}, {varType} and {define}.

Now the IDE can correctly autocomplete.

How to save work? How to write a template class or {varType} tags as easily as possible? Get them generated. That is precisely what pair of tags {templatePrint} and {varPrint} do. If you place one of these tags in a template, the code of class or template is displayed instead of the normal rendering. Then simply select and copy the code into your project.

{templateType}

The types of parameters passed to the template are declared using class:

{templateType MyApp\CatalogTemplateParameters}

{varType}

How to declare types of variables? For this purpose use tag {varType} for an existing variable, or {var}:

{varType Nette\Security\User $user}
{varType string $lang}

{templatePrint}

You can also generate this class using the {templatePrint} tag. If you place it at the beginning of the template, the code of class is displayed instead of the normal template. Then simply select and copy the code into your project.

{varPrint}

The {varPrint} tag saves you time. If you place it in a template, the list of {varType} tags is displayed instead of the normal rendering. Then simply select and copy the code into your template.

The {varPrint} lists local variables that are not template parameters. If you want to list all variables, use {varPrint all}.
