Regexp

Regular expressions are represented by the regexp literal:

def foo_or_bar = ~/foo|bar/
def heeello    = ~/h(e+)llo/
def integer    = ~/\d+/

A regular expression literal is character by ~/ and ended by / character.

It can be followed by these modifiers:

• i: case insensitive matching
• g: global replace or split, see below
• m: multiline matching, ^ and $ represent the beginning and end of a line
• s: the dot . will also match newlines (Neko, C++, PHP, Flash and Java targets only)
• u: use UTF-8 matching (Neko and C++ targets only)

For example

def r = ~/foo/img

Slashes must be escaped:

def slash = ~/\//
