To use lein run, you need to do two things: 1) Write a -main function (defn -main [] ... ) in whatever namespace you like (you could put it in the core namescape, like you did in your echo statement for the (println "foo")). For example:
(defn -main [] (println "foo")) 2) Specify which namespace holds this main function in your project.clj file in the root of your project. It's just another entry, like :dependencies, and it looks like this: :main foo.core Now when you run 'lein run', it will find your main function in that namespace and run it. If this seems a bit random, it's part Clojure's Java heritage. It's basically a shortcut for running your program as if it were an exectuble jar, which must have a "main" function that acts as an entry point for the program. The command 'lein run' allows you to treat your program as an executable jar without having to actually run 'lein uberjar' and then execute it separately. -Daniel -- You received this message because you are subscribed to the Google Groups "Clojure" group.
