Hide private subgenerator namespaces

[SBoudrias]

With composability becoming more common, we end up with some very specific subgenerators that may clutter the yo gen --help interface. We should probably offer a way to hide some "private" subgenerator in that screen.

My initial thought is to hide any subgenerator name starting with an underscore.

Hi, I want to take this issue, can you point me to the code that manages this

Hej @buoyantair, you should have a look over here: https://github.com/yeoman/yo/blob/master/lib/routes/install.js#L51-L62

Do you know how to run your locally changed version of yo? You could use npm link or yarn link to accomplish that.

You might want to create a generator to test this with generator-generator which you can also use via npm link.
