sideLength :: HalmaGrid size -> Int Source
Numbers of fields on each straight edge of a star-shaped halma board of the given size.
numberOfFields :: HalmaGrid size -> Int Source
Total number of fields on a halma board of the given size.
data HalmaDirection Source
The six corners of a star-shaped halma board.
rowsInDirection :: HalmaDirection -> (Int, Int) -> Int Source
From the point of view of the given corner: On which row lies the given field? The row through the center is row zero, rows nearer to the corner have positive, rows nearer to the opposite corner negative numbers.
corner :: HalmaGrid size -> HalmaDirection -> (Int, Int) Source
The corner corresponding to a direction on a star-shaped board of the given size.
type Team = HalmaDirection Source
The corner where the team starts.
startCorner :: HalmaGrid size -> Team -> (Int, Int) Source
The position of the corner field where a team starts.
endCorner :: HalmaGrid size -> Team -> (Int, Int) Source
The position of the end zone corner of a team.
data HalmaBoard size Source
Map from board positions to the team occupying that position.

getGrid :: HalmaBoard size -> HalmaGrid size Source
fromMap :: HalmaGrid size -> Map (Index (HalmaGrid size)) Team -> Maybe (HalmaBoard size) Source
Construct halma boards. Satisfies fromMap (getGrid board) (toMap board) = Just board.
lookupHalmaBoard :: (Int, Int) -> HalmaBoard size -> Maybe Team Source
Lookup whether a position on the board is occupied, and
Arguments
| :: (Int, Int) | start position |
| -> (Int, Int) | end position |
| -> HalmaBoard size | |
| -> Either String (HalmaBoard size) |
Move a piece on the halma board. This function does not check whether the move is valid according to the Halma rules.
initialBoard :: HalmaGrid size -> (Team -> Bool) -> HalmaBoard size Source
