var ExtRegex = regexp.MustCompile("(M|m)(p|P)(3|4))|((F|f)(L|l)(A|a)(C|c))$")
with a ./prog.go:10:18: regexp.MustCompile("((M|m)(p|P)(3|4))|((F|f)(L|l)(A|a)(C|c))$") (value of type *regexp.Regexp) is not constant Actual error I get is "error parsing regexp: unexpected ): `(M|m)(p|P)(3|4))|((F|f)(L|l)(A|a)(C|c))$`" It is missing a parentheses. This compiles fine: var ExtRegex = regexp.MustCompile("((M|m)(p|P)(3|4))|((F|f)(L|l)(A|a)(C|c))$") Note that there are two parentheses after the double-quote. -- You received this message because you are subscribed to the Google Groups "golang-nuts" group.
