This component requires the [Xdebug] PHP extension to be installed.


Installation
------------

To install the latest stable version of this component, open a console and execute the following command:
```
$ composer require ajgl/breakpoint-twig-extension
```


Usage
-----

The first step is to register the extension into the twig environment
```php
/* @var $twig Twig_Environment */
$twig->addExtension(new Ajgl\Twig\Extension\BreakpointExtension());
```

Once registered, you can call the new `breakpoint` function:
```twig
<!DOCTYPE html>
<html lang="en">
  <head>
    <meta charset="utf-8">
    <title>title</title>
  </head>
  <body>
    {{ breakpoint() }}
  </body>
</html>
```

Once stopped, your debugger will allow you to inspect the `$environment` and `$context` variables.

### Function arguments

Any argument passed to the twig function will be added to the `$arguments` array, so you can inspect it easily.

```twig
<!DOCTYPE html>
<html lang="en">
  <head>
    <meta charset="utf-8">
    <title>title</title>
  </head>
  <body>
    {{ breakpoint(app.user, app.session) }}
  </body>
</html>
```

Symfony Bundle
--------------

If you want to use this extension in your Symfony application, you can enable the
Symfony Bundle included in this package.

The bundle will register the twig extension automatically. So, once enabled, you
can insert the `breakpoint` twig function in your templates.

### Symfony 2/3

```php
// app/AppKernel.php
if (in_array($this->getEnvironment(), array('dev', 'test'), true)) {
    $bundles[] = new Ajgl\Twig\Extension\SymfonyBundle\AjglBreakpointTwigExtensionBundle();
}
```

### Symfony 4

```php
// config/bundles.php
//...
return [
    //...
    Ajgl\Twig\Extension\SymfonyBundle\AjglBreakpointTwigExtensionBundle::class => ['dev' => true]
];
```
