Stateful agents

Hi! Have you tried to create stateful agents? This would be useful for implementing long running business processes. The state would be saved to db for durbality and atomicity. In case of crash, the process implemented as agent would continue to execute from the last durable state. I have impleme

Argslist of fn?

Hello, Is there any chance to get a list of args like it is for functions defined by defn ? I would like to use (count (first (:argslist (meta (fn[ a ] (println a)) for my function which would return wrapper which can accept optional arguments. Optional args would be decelerated not by caller

Re: 1.2 contrib shuffles

Agree with Daniel Janus. There are some conflicts without any reason. This should be cleaned up for 1.2.1 version. More over when I build clojure-contrib-1.2.jar I get 4 failures on tests due to. It shouldn't appear in a final versions. All contributors and Rick do a great job but you should think

Dynamic gen-class

Hi, Is there any way to generate class in runtime and then use it? How far I can only generate interfaces. This works: (do (gen-interface :name test.commons.Me :methods [[ me [ String ] void ]]) (def z (reify test.commons.Me (me [t z] (println "hello wor

Re: Interface to integrate transactions with Clojure transactions

Not good, since if database commit fail it is too late for dosync to rollback. In fact database commit should somehow cooparate with dosync commit which is just a case of distributed transaction. On 10 Cze, 23:11, James Reeves wrote: > On 10 June 2010 11:26, Michael Jaaka wrote: > > &

Interface to integrate transactions with Clojure transactions

Re: How to make that eval could see its caller context

Hmmm, I have just missed on thing. The problems comes when evaluation is in another thread. (defn sleep[n] (Thread/sleep n)) (future (eval (load-string "((fn[] (sleep 100) (println \"wowo\")) )") )) The solution is: (defn sleep[n] (Thread/sleep n)) (let [a (get-thread-bindings) ] (future (wi
