Hm, okay cool. I'll assume for now that this is fine. Thanks!

It actually makes it a little easier, because instead of cloning rules for the class-combination selectors, I can just add the combo selector to any rule that has one of the component selectors. So:

<span class="apple banana">Hello World!</span>

span.apple {
    color: red;
}

Becomes:

<span class="apple-banana">Hello World!</span>

span.apple,
.apple-banana {
    color: red;
}

Just, easier than copying rules and declarations around wholesale...

Anyway, I was sick for a couple of days, but I have it working now. At least all of my unit tests are passing. Assuming you have gorilla.epub you can do:

var allscribe = require('allscribe');

var gorilla = allscribe.openEpub('gorilla.epub');
gorilla.process(function(unpacked){
    unpacked.simplifyCssAndMarkup(); // handles multi-element and such complex selectors
    unpacked.mergeMarkupClasses();   // handles multiple classes on an element
    return 'silverback';
});

That'll get you silverback.epub with the various modifications done. Whew.

Anyway, I'll be incorporating all this into my current workflow, start testing how my book looks on K1, etc. But it's a good start, I think. Too bad it's probably not all that accessible to non-scripters.

(I would ask you to give it a shot, seeing that you are a scripter, but all your stuff is custom anyway )
