2010.08.22. ----------- Did you see that the 1.2 release of Clojure seems to listen on a port, well when i start it under Leiningen anyways. I use leiningen (http://github.com/technomancy/leiningen) to manage my closure projects. Last week Clojure 1.2 was release and I updated my dependencies. The usual way for me to get a REPL is it use the command "lein repl" in my project. Now since the upgrade I see the following : len$ lein repl "REPL started; server listening on localhost:1963." clojure.core=> And I can telnet to that port and get a REPL ! So i was thinking that might help you with Slimv ?
