Well...the iterations would be fairly massive, I'd think.
I mean, you'd have to (I don't program, so--those with real brains, leap in) aggregate ALL the styles and elements; probably doing so from the top-down, so most-used to least-used makes the most sense; search for all instances of "p," first, and then all classes used in the ePUB--and then do a string-match in the CSS...does that sound right, ye olden programmers? I mean, it seems more efficient to do it by element and then by class, but sometimes, what seems elementary
(sorry, sorry, you guys KNOW I can't resist bad punnage!) isn't.
We use something SOMEWHAT like this in two places; we have a PERL script and an NTPro script that both check for this--but it's in the HTML. I don't know how we'd adopt it to run inside Sigil, unless we took the additional steps of copying the file, merging it, and exploding it, but even so...it would be a SLICK addition in Sigil. I would infinitely rather the "used in the ePUB but not in the stylesheet" functionality than simply cleaning up the Stylesheet. I know some folks need that--and it would be nice fudge topping--but it's not as needed as the inverse. We have a House CSS that we use, so cleanup isn't as important for us, in the CSS itself...but I think everyone would love the missing classes thing.
