rex.new

Summary

Compiles a regular expression

Prototype

re = rex.new (pattern, flags)


Description

This compiles a pattern, returning a regular expression object that can be used to test regular expressions. For example:


re = rex.new ("(.+) goes (.+)")


Flags are optional. If you want to use them you can use the rex.flags () function to convert various flags into numbers.
