Data structures to represent the possible chess pieces.
Convert the chess piece to its unicode equivalent.
Pattern synonyms of special pieces

Description

One can make use of a block 2600 and block 1fa00 of Unicode characters to render chess characters. One can render chess characters as netral, white, or black pieces, for such pieces one can render these rotated by 0, 90, 180 and 270 degrees. Knights can be rendered on 45, 135, 225 and 315 degrees as well. Furthermore unicode allows to render an equihopper, and special variants like a knight-queen, knight-rook, and knight-bishop.

The module contains pattern synonyms for names that are often given to the pieces.

Data structures to represent the possible chess pieces.

data ChessColor Source #

The color of a chess piece, this can for most pieces be Black, White, or Neutral.

Constructors

White	White color.
Black	Black color.
Neutral	Neutral chess pieces, sometimes depicted half white and half black.
