Re: Extending clojure.contrib.json.write/print-json
Hi Josip, The latest version of c.c.json dispatches on the "type" function, which in turn uses "class." It should be pretty easily extendible. -Stuart Sierra On May 12, 9:26 am, Josip Gracin wrote: > Hi! > > I'm querying a DB and getting java.sql.Timestamp in results, among > other things.

Re: Extending clojure.contrib.json.write/print-json
Josip, You might want to look at Dan Larkin's clojure-json library at http://github.com/danlarkin/clojure-json which supports extensions via dispatch as you suggest.

Extending clojure.contrib.json.write/print-json
Hi! I'm querying a DB and getting java.sql.Timestamp in results, among other things. When I use print-json on this, timestamps are serialized as #. Stuart, any chance you could make the dispatch function for clojure.contrib.json.write/print-json more open for extensions? Unless I'm missing something, changing ":else :default" to ":else (class x)" in the print-json dispatch fn definition would enable adding serialization for custom objects. (defmulti print-json (fn [x] (cond (nil? x) nil (map? x) :object (coll? x) :array (keyword? x) :keyword :else :default))) -- mr.sc.
