mkRegex :: String -> Regex Source #

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 Source #

Arguments

:: 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 Source #

Arguments

:: 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
