Thanks, but I'm looking for something that would let me sent strings between programs on localhost.

Re: Callbacks as Sequences
I've seen that and think it's awesome. This would be used for Node.js. I whipped this up to show what a Clojure version might look like. Basically each body form after the first is inserted where (cb) is found in the previous form. ; Definition (defmacro defseq [fn-name params & body]) ; Example usage (defseq request-handler [req resp] ((. resp (set-header "Content-Type" "text/html")) (exists "some-file.txt" (cb))) (fn [exists] (if exists (read-file filename "utf8" (cb)) (. resp (end "File Not Found" (fn [err data] (if err (. resp (end "Internal Server Error")) (. resp (end data) On Wednesday, February 6, 2013 2:13:33 PM UTC-5, Max Penet wrote: > > Hi, > > jayq includes something similar (nicer imho).

Re: Callbacks as Sequences
Hi, jayq includes something similar (nicer imho). It takes the form of a let like construct (let-deferred [a (jq/ajax "http://localhost:8000/1.json";) b (jq/ajax "http://localhost:8000/2.json";)] (do-something-with-result (merge a b foo))) It also supports :let and :when intermediary steps. more examples can be found here: https://github.com/ibdknox/jayq#jayqmacros-source and the macro: https://github.com/ibdknox/jayq/blob/master/src/jayq/macros.clj#L15 https://github.com/ibdknox/jayq/blob/master/src/jayq/core.cljs#L516 Max On Wednesday, February 6, 2013 7:45:36 PM UTC+1, da...@dsargeant.com wrote: > > I'm not to clojure/clojurescript and was wondering if anyone has taken a > crack at writing a macro that transforms callbacks into a sequence.

Callbacks as Sequences
I'm not to clojure/clojurescript and was wondering if anyone has taken a crack at writing a macro that transforms callbacks into a sequence. There is an awesome implementationion in LispyScript show here: https://gist.github.com/santoshrajan/3715526. Thanks for help.
