Die objektorientierte Schnittstelle
Ruby bietet über die Klassen Regexp und MatchData sowie einige eingebaute Methoden der Klasse String eine objektorientierte Regex-Schnittstelle.
Darüber hinaus bietet Ruby die /.../- und =~-Operatoren, um eine Perl-artige Operatorensyntax zu ermöglichen. Der Operator /.../ ist ein Synonym für Regexp.new, und =~ ist ein Synonym für String#match. Der Operator /.../ wird häufig eingesetzt, um einer Methode ein Regexp-Objekt zu übergeben, z.B. "foo, bar, frog".split(/,\s*/).
