Parallel Game of Life

A couple of small corrections: the :gen-class directive needs (:main true) to tell it you have a main function: (ns temp-converter (:gen-class (:main true)) and the main function needs an argument declaration: (defn -main [] (main)) Tom On Mar 15, 2:05 am, Laurent PETIT wrote: > Hello, >

Hello, And one more added benefit is that if you (or something using your namespace) uses IDEs that auto-load (or auto-compile) the clj files each time they are saved (such as clojuredev does), it would be impractical to have a namespace auto-execute itself. Because then, the auto-load functionali
