Regular expressions |

type Regex = Regex |
A compiled regular expression |

expressions). |

:: String | The regular expression to compile | -> Bool | True <=> @^@ and @$@ match the beginning and
end of individual lines respectively, and '.' does not
match the newline character. | -> Bool | True <=> matching is case-sensitive | -> Regex | Returns: the compiled regular expression | Makes a regular expression, where the multi-line and
case-sensitve options can be changed from the default settings. |
|
|
matchRegex |
:: Regex | The regular expression | -> String | The string to match against | -> Maybe [String] | Returns: Just strs if the match succeeded
(and strs is the list of subexpression matches),
or Nothing otherwise. | Match a regular expression against a string |
|
|
matchRegexAll |
:: Regex | The regular expression | -> String | The string to match against | -> Maybe (String, String, String, [String]) | Returns: Nothing if the match failed, or: Just ( everything before match,
portion matched,
everything after the match,
subexpression matches ) | Match a regular expression against a string, returning more information
about the match. |
