Lightning Talk: Using Regular Expressions in Erlang
summary
Describes practical use of Erlang’s re module (PCRE-compatible) with concrete checks: union, intersection and subtraction of character classes compile and run as expected, verified by eunit tests, matching .NET/Java behavior. Notes gaps in re documentation, applies patterns from Fitzgerald and Friedl-style regex books, and publishes three helper libraries on hex.pm that implement common helpers and examples for substitution, splitting and class operations.
