Description

AUTHOR: Dr. Alistair Ward
DESCRIPTION

Types

Type-synonyms

type CoordinatesByLogicalColour = ArrayByLogicalColour [Coordinates] Source #

A list of coordinates for each logical colour.

Data-types

data CoordinatesByRankByLogicalColour Source #

This structure allows one to determine the set of coordinates where a type of piece is located.
CAVEAT: the list of coordinates is unordered, so test for equality using deconstruct . sortCoordinates .

Functions

findPassedPawnCoordinatesByLogicalColour :: CoordinatesByRankByLogicalColour -> CoordinatesByLogicalColour Source #

For each logical colour, find the coordinates of any passed Pawns (https://en.wikipedia.org/wiki/Passed_pawn).

findPiecesOfColour Source #

Arguments

:: LogicalColour	The logical colour of the pieces to find.
-> CoordinatesByRankByLogicalColour
-> [LocatedPiece]

Locate all pieces of the specified logical colour.

assocs :: CoordinatesByRankByLogicalColour -> [(Piece, [Coordinates])] Source #

Build an association-list.

listCoordinates :: CoordinatesByRankByLogicalColour -> [Coordinates] Source #

Access the coordinate-lists.

Accessors

getKingsCoordinates Source #

Arguments

:: LogicalColour	The logical colour of the `King` to find.
-> CoordinatesByRankByLogicalColour
-> Coordinates

Get the coordinates of the King of the specified logical colour.

dereference :: LogicalColour -> Rank -> CoordinatesByRankByLogicalColour -> [Coordinates] Source #

Dereference the array.

Constructor

fromMaybePieceByCoordinates :: MaybePieceByCoordinates -> CoordinatesByRankByLogicalColour Source #

Constructor.

Mutators

movePiece Source #

Arguments

:: Move
-> Piece	The piece which moved.
-> Maybe Rank	The (possibly promoted) rank to place at the destination.
-> Either Coordinates (Maybe Rank)	Either the destination of any passed `Pawn`, or the rank of any piece taken.
-> Transformation

Adjust the array to reflect a new move.

sortCoordinates :: Transformation Source #

Independently sort each list of coordinates.
