HChess is an attempt to learn haskell by means of writing a chess engine, something I’ve previouisly done in C++.

This software is in it’s very early stages and only currently supports pretty printing of an initial board state.

Current features:

• Data types for Ranks and Files.
• 0x88 Board representaiton using Array indexed by Locus.
• Translation functions for translating between 0x88 locaii and File, Ranks.
• Direction types and applications to Locus to generate a new Locus.
• Piece data types:
  • Piece Kind
  • Colour
  • Piece
• Creation of starting board.
• Pretty printing of game state.
• GameState class that encapsulates all game state.
• Move generation that’s valid up to perft 5 from starting position and various other positions.
• Perft testsuite with Travis CI integration.
• Game tree search with:
  • Alpha Beta Pruning
• UCI implemtnation, allowing communication with various chess programs, such as Cute Chess.
• Iterative deepening
• Use Template Haskell to precompute movement rays during MoveGen.
