===================================
Portable Game Notation (PGN) parser
===================================

.. contents::


Description
===========

This package provides a parser for chess game scores in `PGN`_ format.

Both the strict export format and many less strict import formats are supported.

Chess variants are not supported.

The game module provides the Game, GameStrictPGN, GameTextPGN, and GameIgnoreCasePGN, classes and the generate_fen_for_position function.

The parser module provides the PGN class and add_token_to_game function.

The PGN.read_games method yields instances of the Game class, or a subclass, generated from a file-like source or string.

The add_token_to_game function searches for the next PGN token in a string and applies it to an instance of the Game class, or a subclass.

The generate_fen_for_position function returns the Forsyth English Notation (FEN) string for the representation of a position in the Game class, or a subclass.

The movetext_parser module provides classes which expect movetext but do not expect it to represent a game.

The tagpair_parser module provides classes which take just enough notice of movetext to correctly spot PGN Tag Pairs and Game Termination Markers.


Installation Instructions

Notes
=====

Project name and package name changed from 'pgn' to 'pgn-read' prior to upload to PyPI.
