Each Erlang Programming source file
is required to be a separate module. Modules are created with the module statement.
-module(utility). % 1 -export([rotate/1]). % 2 % 3 rotate([H|T]) -> % 4 T ++ [H]. % 5
"utility" is the module created by the file utility.erl
utility functions like rotate can be imported elsewhere with:
so now we do not need to use the "utility:" prefix. Importing modules is not generally recommended. This is very similar to python and Java imports.Last modified on 20 August 2010, at 19:42
