I knew there must be tools to solve this problem, so, searching around, and reading through my Erlang book, I came across Dialyzer, or (“a DIscrepancy AnalYZer for ERlang programs”). Basically, it does a static source code (or compiled byte code) analysis of your program(s) and tells you when there are unknown function calls, or places in the code that can’t be reached, etc… It’s very handle, and lets work on coding and testing the functionality of my code, rather than the runnability of my code. This tool is a must-have for Erlang programmers.

Peace and chow,

Ranok
