I once made a program that did somthing like this.
I simlply removed all strings, replaced them with negitive integers,
then removed comments as above. I then went back and replaced
the negative integers with the strings(ignoring any that might
have been cut out with the comments).
This worked fine for:
--A comment
blah("--blah")--A comment
blah("--blah")--A comment with -- in it
blah("--blah")--A comment with "quotes" in it
and also handled strange lines like these by ignoring \"
and removing anything from a " to the end of the line
if there wasn't an ending ".
blah("--\"blah\"")--A comment with -- and a " in it
