zipWithEqual :: String -> (a -> b -> c) -> [a] -> [b] -> [c]Source

zipWith3Equal :: String -> (a -> b -> c -> d) -> [a] -> [b] -> [c] -> [d]Source

zipWith4Equal :: String -> (a -> b -> c -> d -> e) -> [a] -> [b] -> [c] -> [d] -> [e]Source

stretchZipWith :: (a -> Bool) -> b -> (a -> b -> c) -> [a] -> [b] -> [c]Source

`stretchZipWith p z f xs ys`

stretches `ys`

by inserting `z`

in
the places where `p`

returns `True`

mapAndUnzip :: (a -> (b, c)) -> [a] -> ([b], [c])Source

mapAndUnzip3 :: (a -> (b, c, d)) -> [a] -> ([b], [c], [d])Source

partitionWith :: (a -> Either b c) -> [a] -> ([b], [c])Source

Uses a function to determine which of two output lists an input element should join

splitEithers :: [Either a b] -> ([a], [b])Source

Teases a list of `Either`

s apart into two lists

lengthExceeds :: [a] -> Int -> BoolSource

(lengthExceeds xs n) = (length xs > n)

lengthAtLeast :: [a] -> Int -> BoolSource

listLengthCmp :: [a] -> Int -> OrderingSource

atLength :: ([a] -> b) -> (Int -> b) -> [a] -> Int -> bSource

`atLength atLen atEnd ls n`

unravels list `ls`

to position `n`

. Precisely:

atLength atLenPred atEndPred ls n | n < 0 = atLenPred n | length ls < n = atEndPred (n - length ls) | otherwise = atLenPred (drop n ls)
