I’ve recently got back to coding Erlang and noticed a neat module that I didn’t know existed that is probably worth writing a blog entry about. I’ve started developing a PubSubHubbub hub in Erlang called Hubbabubba and I’m using the great Mochiweb HTTP library as the HTTP server implementation. I discovered the reloader.erl module that comes with Mochiweb. It automatically reloads the code when you have the application running and you modify the code (remember to compile as well). This is something that I’ve found very useful when developing with Django or AppEngine and I’m really satisfied that there is a similar solution for Erlang as well.
