Description

AUTHOR: Dr. Alistair Ward
DESCRIPTION

Defines one move (actually just a half move AKA "ply") of a piece.
Similar to Vector, but the position is fixed.

Synopsis

data Move
tag :: String
nPliesPerMove :: NPlies
measureDistance :: Move -> Vector
interpolate :: Move -> QualifiedStraightLine
mkMove :: Coordinates -> Coordinates -> Move
isPawnDoubleAdvance :: Move -> LogicalColour -> Bool

Types

Type-synonyms

data Move Source #

A move of a piece.
Most modern chess-notations (except Standard Algebraic) start with similar information, but also define ancillary information which is captured in MoveType.

Constants

tag :: String Source #

Used to qualify XML.

nPliesPerMove :: NPlies Source #

The constant number of plies per move.

Functions

measureDistance :: Move -> Vector Source #

Measures the signed distance between the ends of the move.

interpolate :: Move -> QualifiedStraightLine Source #

Generates a line of coordinates covering the half open interval (source, destination].

Constructors

mkMove :: Coordinates -> Coordinates -> Move Source #

Smart constructor.

Predicates

isPawnDoubleAdvance Source #

Arguments

:: Move
-> LogicalColour	Defines the side whose move is referenced.
-> Bool

Whether the specified move is a Pawn's initial double-advance.
CAVEAT: failing this test guarantees that the move isn't a Pawn's double-advance, but passing only guarantees that it is, if it was a Pawn which moved & that the move is valid.
