.registered(app) ⇒ Object

Um, dragons… Fucking swarm… But I’ll try to explain this anyway. We’ll scan the defined settings.validation dir for dirs. Those found dirs will denote <resource>s. Then, we will scan the “resource” dirs for files. These files will represent one http <verb>.yaml each. And then, we create hierchy of validation schemas following this pattern: ::setting.validation::<resource>::<verb_schema> where the <verb_schema> equals <verb>.capitalize and contains parsed contents of <verb>.yaml file. Please note that I haven’t used a single (.*_)eval even though I was terribly tempted. And I also documented this method. I’m so awesome, considerate and drunk, am I not? Uh, yea, and notice the nice cascade of ‘end’s on the end
