The reason I want to do this is I have come client side javascript (for android and ios + phonegap) and it would be nice to use julius to automatically generate some javascript code for the xcode project.  To be specific, i have a .js file like this:

Well, the first thing you'd want to look at is renderJulius[1]. For
that to work, you'll need the URL rendering function, which is what I
assume you're asking for, and is slightly harder to get. For that,
you'll probably want the joinPath method of the Yesod typeclass. Let
me know if you have trouble, I can (at a later date) write up an
example.
