Re: Using a Regexp in String#gsub in C

You can create the string first (without slashes), then create the =
regexp using the string, finally call gsub as usual, passing the regexp =
value.

For example:

  VALUE pattern =3D rb_str_new2("some-pattern");
 VALUE regex =3D rb_reg_new_str(pattern, 0);

Hope that helps,
Ammar
