Is it possbile to create custom library with namespace

Question

It is possible to create library package with namespace as below?

namespace Main{
  class PrefixFolderLib1{
    //functions
  }
}

Not sure how the JLoader will understand the namespace.

Answer 1

Sure. For example, create mylib folder in /library, and a file Myclass.php with the following content:

namespace mylib;

class Myclass
{
}

You can register your namespace with

JLoader::registerNamespace('mylib', JPATH_ROOT . '/libraries');

And access your class with \mylib\Myclass. Personally, I create a system plugin to do it automatically:

public function onAfterInitialise()
{  
   JLoader::registerNamespace('mylib', JPATH_ROOT . '/libraries');
}
