I’ve decided to dig a bit into Erlang.
The setup has been painless. I first installed Macports (look here for a step by step guide). With this installed, to install Erlang is a single command:
sudo port install erlang
Then I looked up the recommended development environment. What a surprise: a lot of people suggest Emacs. And so I followed the instructions of lisp Guru extraordinaire Bill Clementson on how to setup Emacs to develop in Erlang. I won’t repeat what he has explained perfectly in the post linked above.
Now since yesterday I am going through “Programming Erlang” with a development Erlang node embedded in my Emacs session and I am enjoying it very much.
My mind wanders freely on the power and the ease Erlang will give me to develop massive, concurrent, real-time, next generation services.
