[erlang-questions] String and single quote escaping

[Sean Cribbs]

Your last one is nearly correct. Try this:

3> io:format("~s~n", [re:replace("single quote ' etc...", "'",
"\\\\&", [{return, list}])]).
single quote \' etc...

Note that I used io:format so you don't get Erlang's term
representation but the literal string output.
