Chess4p

A library for chess related functionality.

The work is inspired by the Python module python-chess,
although the main emphasis for Chess4p is thought to be on
features needed by chess database applications, and not so much features needed by
chess engines.


Features include

* Legal moves
* Board state handling, FEN input/output
* Perft testing
* UCI move input/output
* SAN move input/output
* PGN file reader

Planned enhancements

* Move and position binary encoding/decoding
* Support for Fischer Random chess
* EPD


Only 64-bit systems are supported, due to heavy use of the 'bitboard' data type.
