| type Regex = Regex |
| A compiled regular expression |
|

expressions). |

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. |
