valuewriteError :: String -> IO ()

valuemapBoth :: (a -> a) -> (a, a) -> (a, a)

valuemapPartTimes :: (a -> a) -> ((a, a), (a, a)) -> ((a, a), (a, a))

valuemapFst :: (a -> b) -> (a, c) -> (b, c)

valuemapSnd :: (a -> b) -> (c, a) -> (c, b)

valuedelta :: Num a => (a, a) -> a

valuemid :: Fractional a => (a, a) -> a

The midpoint of two values

valueremoveCommon :: Eq a => [a] -> [a] -> ([a], [a])

valuereadMaybe :: Read a => String -> Maybe a

value(!!!) :: [a] -> Int -> a

like !! selects nth element from xs, but wraps over at the end of xs

Example1 expression

>>> map ((!!!) [1,3,5]) [0,1,2,3,4,5][1,3,5,1,3,5]

valuenth :: Int -> [a] -> Maybe a

Safer version of !! -

valueaccumulate :: Num t => [t] -> [t]

valueenumerate :: [a] -> [(Int, a)]

enumerate a list of things

Example1 expression

>>> enumerate ["foo","bar","baz"][(1,"foo"), (2,"bar"), (3,"baz")]

valuewordsBy :: (a -> Bool) -> [a] -> [[a]]

split given list of a by given single a, e.g.

Example1 expression

>>> wordsBy (== ':') "bd:3"["bd", "3"]

valuematchMaybe :: Maybe a -> Maybe a -> Maybe a

valuefromRight :: b -> Either a b -> b
