character classes and special symbols #2

Closed sebfisch closed 14 years ago

sebfisch commented 14 years ago

Extend the parser such that groups of symbols written as [sebf], [h-k], [^abc], and [^h-k] as well as special symbols such as . or \d can be used in regular expressions.

To do so, change of the RegExp data type. The Symbol constructor should take a predicate :: a -> Bool rather than a symbol :: a.
