Clipboard support in jQuery using revealing module pattern
Interesting question, your code is very readable.

However, if you only reveal an init function, then really there is not much sense in using a revealing pattern.

I would probably not self execute styleGuideHandler but pass it to the jQuery call:

$(document).ready(styleGuideHandler);


Other than that, just for giggles, I might also pass the few globals it uses:

$(document).ready(styleGuideHandler( document, Clipboard, hljs ));


Then when styleGuideHandler is executed, you run the code in init.
