In short, you have to provide the lexical analyzer
yourself. The canonical handwritten example is
erl_scan.erl

If you are feeling adventurous, you can also have a
look at 

 jungerl/lib/smart_exceptions/lex.erl

which is a lex-like utility. There are docs at the
front of the file and some usage examples at the end.

Best,
Thomas
