Override the default "App" namespace

[jt-adwisemedia]

Summary

We're trying to use blade-generate, but we're getting this error
Error: You don't appear to have installed or activated Sage 9!

I then took a quick look in the package and it appears that you're looking for the App\sage namespace\function.

We're using a heavily customized theme where we've overridden the default App namespace,
which is fully supported in the Sage theme.

Even some packages like soberwp have added wordpress filters to allow users/themes to override the default namespace.

Potential Solution / Examples

../vendor/soberwp/controller/controller.php:

 10  function sage()
 11  {
 12      // Determine if project namespace has been changed
 13      sage = apply_filters('sober/controller/sage/namespace', 'App') . '\sage';
 14  
 15      // Return the function if it exists
 16      if (function_exists($sage)) {
 17          return $sage;
 18      }
 19  
 20      // Return false if function does not exist
 21      return false;
 22  }

../vendor/soberwp/controller/src/Loader.php:

 60  protected function setNamespace()
 61  {
 62      $this->namespace =
 63          (has_filter('sober/controller/namespace')
 64          ? apply_filters('sober/controller/namespace', rtrim($this->namespace))
 65          : 'App\Controllers');
 66  }

Is it possible for you to make a similar solution with filters for this package?

I haven't personally worked with WP_CLI before so i don't know if you have full access to WordPress function or not, like apply_filters();

Not including any dev environments such as PHP version etc since this is more of a logical issue.
