Hi Evan, I think Hiccup is a also a good starting point for this. In fact 99% of the port is already working. The last thing I struggle with is actually only cosmetics, like carrying over the meta data with the arglist and documentation.
Why do you think it is impossible to have the same API in Clojure and ClojureScript? If you look at the header of the following file you can see that it's using exactly Hiccup's API (except :use-macros). https://github.com/r0man/hiccup/blob/clojurescript/test/cljs/hiccup/test/page.cljs Your lein-cljsbuild will take care of modifiying the :use-macros clause in the namespace declaration when used in crossover files. But maybe I missed something? Roman.
