Implicit Fluid Namespaces

Fluid templates allow you to create your own ViewHelpers (VHs). You just have to declare where those VHs can be found:

{namespace cic = CIC\MyExt\ViewHelpers}
...
<cic:special arg1="blah" />

That will use the CIC\MyExt\ViewHelpers\SpecialViewHelper class. That's great! But why do I need to declare the namespace? Well, to avoid conflicts. It's possible that your "cic:special" could refer to the SpecialViewHelper from some other extension somewhere else. Is it likely that you're going to run into name collisions? No. Not likely at all.

If the cicbase typoscript is loaded in the project, you'll be able to declare your ViewHelper namespaces implicitly in typoscript:

plugin.my_ext {
  settings {
    fluidNamespaces {
      cic = CIC\MyExt\ViewHelpers
    }
  }
}

Now, you can use <cic:special> in all your templates without needing to re-declare the namespace.
