Of course, defining the function makes it easier to invoke your code if you think it might have wider usefulness. Joshua On Sun, Mar 15, 2009 at 3:55 AM, Keith Bennett keithrbenn...@gmail.comwrote: Is it a good idea or a bad idea to provide a main() function as the program's entry point? As

Hi Keith, IMO it is slightly better to use a function as you described. The benefit being that it makes it easier to test your helper functions without running the main application. For instance if you comment out (main) and load the file to the REPL or call a test function instead. It seems the

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

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

Main Function for Program Entry Point

2009-03-14 Thread Keith Bennett
Is it a good idea or a bad idea to provide a main() function as the program's entry point? As an example, I have a program at http://is.gd/ndTV. If you look at the bottom you'll see (unless and until I change it) the specification of a main function, and then a call to it. I'm aware that I
