I could be wrong here, but I have the feeling that it *should* be possible to build up such a solution based on the what Yesod provides in widgets. Obviously, such a solution would add much more power than what Yesod provides, but I think it already provides enough of the low-level details to get what you need. I'm not trying to convince you to use Yesod for this, but I would be very appreciative to hear what Yesod's widgets are lacking to get the functionality you want.

Maybe. I don't know, maybe it's just my lack of imagination :). Either way, I don't really think it would make much sense to do the thing in Yesod, since I don't really foresee it being able to integrate with any other Yesod apps/widgets, nor really taking advantage of any of the high-level bits of Yesod.

One thing I am looking for is a convenient way to autogenerate JavaScript. I could use the "blaze" string builders (or builders for Text or whatever), but if there is some library for building JS in a safer way than just string concatenation. As with the HTML, I'm also going to be generating this JS extremely dynamically. I know about Julius, but what I (think) I really need is a sort of AST datatype for JavaScript with a toText/toBS printer.

Alan Zimmerman put together a Javascript minification package[1], and in the process created a full-blown Javascript lexer/parser/AST package[2]. That may be somewhere do start.

Thanks for the pointer. Cheers,
