Passing helper php function to pug context ?

[mcoenca]

(Not sure if it's not possible or if I have not found the right way to do it ?? I am not very experienced in php scopes sorry if this is a stupid question...)

I would like to be able to pass a php function to pug at render time, to be able to call it directly in my template. Without resorting to a global function.

That way I would be able to use the same helper function name in all my template, even if its behaviour is dependent of the route context.

Something like:

// in HomeController.php

public function get() {
    function pathFor($pathName) use ($this) {
        return $this->router->pathFor($pathName);
    }

   return $this->pug->render('productPage.pug', $this->templateParams, [pathFor?] )
}

//- in productPage.pug

p
    #[a href=pathFor('/home')) Click here quick quick quick QUICK !]

would get me

<a href="/amazing-product-you-will-like-and-buy-home-page"> Click here quick quick quick QUICK ! </a>

Thanks for your help !
Btw: Amazing package 💯

Hi,

The easiest in your case would probably be a closure:

public function get() {
    $routerPathFor = array($this->router, 'pathFor');
    $pathFor = function ($pathName) use ($routerPathFor) {
        return call_user_func($routerPathFor, $pathName);
    };
    // Depending on your PHP version you can use directly $routerPathFor

   return $this->pug->render('productPage.pug', $this->templateParams, array(
      'pathFor' => $pathFor
   ));
}

You can also use share to get the function available in any template:

// somewhere in a global place after $this->pug is instanciated
// for example, the constructor of an abstract class that all controllers extend
$this->pug->share('pathFor', $pathFor);

With such a template:

a(href=$pathFor('foo'))=$pathFor('bar')

I hope it solve your problem.

Perfect ! Well that means I need to dive in php closures a bit deeper...

Thanks for your very fast answer 👍
