pgnlexer

This modules uses David M. Beazley ply.lex modules to implement a PGN lexer.

It may be inaccurate in more than one places but works pretty well for PGNs found in the wild.

Example usage:

import lexer

with open('filename.pgn') as pgn_file:
    pgn_text = pgn_file.read()

tokens = lexer.tokenize(pgn_text)
