|
| Regular expressions
|
|
| Regex |
|
| mkRegex :: String -> Regex |
| Makes a regular expression with the default options (multi-line,
case-sensitive). The syntax of regular expressions is
otherwise that of egrep (i.e. POSIX "extended" regular
expressions).
|
|
| mkRegexWithOpts |
| :: 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-sensitive 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.
|
|
|
| subRegex |
| :: Regex | Search pattern
| | -> String | Input string
| | -> String | Replacement text
| | -> String | Output string
| Replaces every occurance of the given regexp with the replacement string.
In the replacement string, "\1" refers to the first substring;
"\2" to the second, etc; and "\0" to the entire match.
"\\\\" will insert a literal backslash.
This is unsafe if the regex matches an empty string.
|
|
|
| splitRegex :: Regex -> String -> [String] |
Splits a string based on a regular expression. The regular expression
should identify one delimiter.
This is unsafe if the regex matches an empty string.
