compileRegex :: Bool -> ByteString -> Regex Source #

Compile a PCRE regex. If the first parameter is True, the regex is case-sensitive, otherwise caseless. The regex is compiled from a bytestring interpreted as UTF-8. If the regex cannot be compiled, a RegexException is thrown.

matchRegex :: Regex -> ByteString -> Maybe [ByteString] Source #

Match a Regex against a bytestring. Returns Nothing if no match, otherwise Just a nonempty list of bytestrings. The first bytestring in the list is the match, the others the captures, if any. If there are errors in executing the regex, a RegexException is thrown.

convertOctalEscapes :: String -> String Source #

Convert octal escapes to the form pcre wants. Note: need at least pcre 8.34 for the form o{dddd}. So we prefer ddd or x{...}.
