Regular expression library like Perl and Ruby's regular expressions.
This package has a module RegexPR.
And RegexPR export functions matchRegexPR and gsubRegexPR.
matchRegexPR :: String -> String -> Maybe ((String, (String, String)), [(Int, String)])
multiMatchRegexPR :: String -> String -> [ ((String, (String, String)), [(Int, String)]) ]
gmatchRegexPR :: String -> String -> [ ((String, (String, String)), [(Int, String)]) ]
getbrsRegexPR :: String -> String -> [ String ]
ggetbrsRegexPR :: String -> String -> [ [ String ] ]
subRegexPR :: String -> String -> String -> String
subRegexPRBy :: String -> (String -> String) -> String -> String
gsubRegexPR :: String -> String -> String -> String
gsubRegexPRBy :: String -> (String -> String) -> String -> String
splitRegexPR :: String -> String -> [String]
Examples
matchRegexPR "ab(cde)f\\1" "kkkabcdefcdefgh" =>
Just (("abcdefcde", ("kkk", "fgh")),[(1,"cde")])
matchRegexPR "(?<=hij)abc" "kkkabchijabcde" =>
Just (("abc",("kkkabchij","de")),[])
gsubRegexPR "\\G(\\d\\d\\d)" "\\1," "123456 789" => "123,456, 789"
subRegexPR "(?<=(.)(.)(.))e" " \\3\\2\\1 " "abcdefg" => "abcd dcb fg"
gsubRegexPR "(?ixm) aBc . # comment \n\n" "abc!" "abc\nABCDAbcAbc" =>
"abc!abc!abc!bc"
gmatchRegexPR "(?=(?<!(?!abc)))abc" "abcdefdefabc" =>
[(("abc", ("", "defdefabc")), []), (("abc", ("defdef", "")), [])]
splitRegexPR "\\s*,\\s*" "a,b ,c\t ,d , e" => ["a","b","c","d","e"]
