Regex package:regex-compat

Regular expression matching. Uses the POSIX regular expression interface in Text.Regex.Posix.

A compiled regular expression.

Replaces/enhances "Text.Regex" One module compat layer over regex-posix to replace Text.Regex. See also https://wiki.haskell.org/Regular_expressions for more information.

matchRegex :: Regex -> String -> Maybe [String]

regex-compat Text.Regex

Match a regular expression against a string.

matchRegexAll :: Regex -> String -> Maybe (String, String, String, [String])

regex-compat Text.Regex

Match a regular expression against a string, returning more information about the match.

mkRegex :: String -> Regex

regex-compat Text.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 -> Bool -> Bool -> Regex

regex-compat Text.Regex

Makes a regular expression, where the multi-line and case-sensitive options can be changed from the default settings.

splitRegex :: Regex -> String -> [String]

regex-compat Text.Regex

Splits a string based on a regular expression. The regular expression should identify one delimiter. This does not advance and produces an infinite list of [] if the regex matches an empty string. This misfeature is here to match the behavior of the original Text.Regex API.

subRegex :: Regex -> String -> String -> String

regex-compat Text.Regex

Replaces every occurrence 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 does not advance if the regex matches an empty string. This misfeature is here to match the behavior of the original Text.Regex API.
