I've been using my own DOM library for a while now which always was fast enough
for me.
I started a new-ish implementation for my react/om experiments and I started
using a simple memoization trick to do the "parsing" bit at most once.
Basically its just (pseudo-ish code, not the actual code)
(defn dom-fn* [kw]
(let [[tag id class] (parse-dom-tag kw)]
(fn [] (create-element tag id class)))
(def dom-fn (memoize dom-fn*))
Trades the parsing bits for one map lookup and one extra function invocation,
seems promising performance wise but too early to tell. Macro proved very
difficult when I tried it because of the nesting of runtime components which
you still need an interpreter for anyways.
Also you don't need to use a regexp to parse the :div.something.other a simple
replace "." with " " yields "something other" which looks alot like the class
string you want. You can translate that in one single loop over the source
string which is faster than a regexp but I never did a real benchmark, it
seemed fast enough. ;)
Maybe these ideas are useful for your library as well, but consider them
half-baked. I don't have anything to show for it yet. :P
Cheers,
