parse :: IArray a Char => String -> (a (Int, Int) Char, (Int, Int)) Source #
Returns the 2D representation of a string by lines and the index of the
only | pipe character on the first line.
move :: Num a => (a, a) -> Direction -> (a, a) Source #
Moves a point one step in a cardinal direction.
joints :: (IArray a Char, Ix i, Num i) => a (i, i) Char -> (i, i) -> [Direction] Source #
Returns the cardinal directions around a point which contain non-space.
