Revision history for Perl extension Chess::PGN::Parse.

0.19 10-Jan-2006

• fixed bug in recursive comment printout. Thanks to Dadi Jonsson for reporting it;
• Added support for comments with newlines in between. Thanks to Marcin Kasperski for the test case.
• Added support for promotions without the equal sign (e.g.: e8Q instead of e8=Q) Thanks to Andrew Nikitin for reporting it.
• Tidied the code a bit.

0.18 25-May-2004

• Broken compatibility release. Perl 5.8.4 won't compile a recursive regex without some minor modifications. Fixed. If you are still using a previous version of Perl, there is no need to switch.

0.17 15-Jul-2003

• Added some more control to parse irregularly formatted tags
• Added set_{tag} methods, to set game, moves, white, black, site, event, eco, elos, result. Such functionality is kept distinct from teh relative {tag} methods, to keep good performance and to avoid problems with existing programs. Thanks to Johannes Fuernkranz for feedback and advice 0.16 09-Jul-2003
• Fixed yet another minor POD formatting problem 0.15 09-Jul-2003
• Fixed minor POD formatting problem 0.14 08-Jul-2003
• Added method add_comments(), to add comments to an already parsed game;
• Modified bahavior of standard_PGN() so that it can use derived class methods for comments. 0.13 07-Jul-2003
• Minor bug in parse_game(). {save_comments => 'no'} did not work as expected. Fixed. 0.12 06-Jul-2003
• Fixed bug in standard_PGN() when printing comments. 0.11 05-Jul-2003
• Added feature in standard_PGN(). Now it can also print comments 0.10 23-Dec-2002
• Changed behavior in parse_game. Now the array in moves() is always initialized and the method returns a valid array also when no moves are found (although it coud empty). 0.09 22-Dec-2002
• Changed parse engine, to make it 5% faster. Thanks to [Tye] 0.08 22-Dec-2002
• Fixed a Regex mistake, which didn't have effect on accuracy, but was affecting performamce negatively. Thanks to Nathan Neff for the tip. 0.07 28-Mar-2002
  • a new read_game() method to support irregular input
    1. no blank line between tags and moves;
    2. no blank line between games
    3. blank line(s) before a game (start of file)
    4. multiple tags in the same line
    5. tags spanning over more lines
    6. No tags (only moves). (can't cumulate with rule 2)
    7. semicolon comments outside the moves.
• The above changes make it possible to deal with Recursive Annotated Variations .
• old read_game() renamed into read_standard_game()
  • modified parse_game() to support non numbered input games
  • modified standard_PGN() to output a blank line between tags and game.
  • Changed dependency. IO::File instead of FileHandle.
• added stronger structures to store comments.

  Calling parse_game(), you can specify if the comments are stored as a 'string' (default), an 'array' of strings, or a 'hol', hash of lists, to identify which type of comment it is (RAV, NAG, brace, semicolon, escaped).

• fixed bug in init(). $self->{GameErrors} was not initialized after each parse.
• fixed bug in parsegame(). FirstMove was not set correctly for games starting with numbers bigger than 1;
• Added handler for the above move numbers in standard_PGN();
  • extended documentation to reflect the changes and explain the module functionality.

0.06 16-Feb-2002

• improved "new" method. Input can be either a string or a file.
• output to standard PGN format. Can also be customized for special output such as HTML. Selection of tags for output is supported.

• bug fix in shrink_epd and expand_epd

0.02 24-Jan-2002

• use Regexp::Common to parse nested parentheses

0.01 21-Jan-2002
