SheetWorker event wildcard

Hey everyone! I was wondering, if sheetworker events support wildcards like on("change:skill_*",...) or some similar behaviour. I've read UniversalSheetWorker article and it is not quite what I'm looking for, since I have a list of a hundred skills and it would be painful (and ugly) to incorporate them all into universal list approach.  Alternatively, I thought about redefining on() function to support wildcards or making some kind of wrapper over it. Is it even possible? I couldn't find any documentation on the internals of script sandbox (I assume sheetworkers run there too, since I couldn't find any mention of them on client-side). The ultimate solution would be to implement my own event listener and that wouldn't be a problem if I knew where the events are coming from.  I'm not hands-on familiar with js but have programming background. 

It doesn't support wildcards. You'd could create your own wrapper for it that would support wildcards, but you'd need to have a list of attributes and such to filter for the right events to register. The sheet workers run in a client side sandbox, so you're limited on what you'll be able to accomplish with creating an alternative event system. 

Thanks Aaron. Follow up question - can I register an event listener without specifying attribute? Something like on("change",...) so that I can process any change event the way I like. 

Not that I have ever seen.

Whatever approach you take, with the limitations of roll20 you have to start off by supplying a hardcoded list of attributes. There's simply no way around it. The Universal Sheet Worker approach, or something like it, is the closest we can get to wildcards.  If you have a list of 100 skills, but each of them follows the same rules, just with different names, a universal sheet worker will be pretty easy. An array or object of 100 items doesnt take much work - and definitely way less than it took to make the html for those attributes.
