elm-2d-array
Provides an ergonomic and fast way to use 2 dimensional arrays in Elm.
Usage
Creating a 2D array
import Array2D
my2dArray : Maybe (Array2D Int)
my2dArray =
[ [ 1, 2, 3, 4 ]
, [ 5, 6, 7, 8 ]
, [ 9, 10, 11, 12 ]
]
|> List.map Array.fromList
|> Array.fromList
|> Array2D.fromRowsGetting an element
anElement : Maybe Int
anElement =
Array2D.get 2 1 my2dArray -- (Just 10)Mapping over the 2D array
incremented : Array2D Int -> Array2D Int
incremented =
Array2D.map (\elem -> elem + 1)
inverted : Array2D Bool -> Array2D Bool
inverted =
Array2D.map not
