Portable Game Notation (PGN) implementation in .NET

Read more about PGN on Wikipedia.

Here is an excellent spec document.

pgn.NET is a library which can be used to handle chess games and read/write them in the PGN format. It is implemented in F# and C# and uses FParsec.

To support as many .pgn file formats as possible the parsers try to be as tolerant as possible. It mostly conforms to this specs. However, other than the specification says we use UTF-8 as encoding, cause it's the 21st century.

//READ FILE
var reader = new PgnReader();
var gameDb = reader.ReadFromFile("Tarrasch.pgn");

Game game = gameDb.Games[0];

Console.WriteLine(game);

This is the initial release of pgn.NET, a library to parse PGN chess databases which includes

• Data model for chess games (Game, Board, move text, move, piece)
• PgnReader (Parser) for the PGN format (http://www.saremba.de/chessgml/standards/pgn/pgn-complete.htm).
  • The parser tries to be as tolerant as possible (there are many variation of the pgn format), so most pgn files should be readable. If not, please file an issue here: https://github.com/iigorr/pgn.net/issues
  • Support for iso-8859 and UTF-8
  • Support for Recursive Annotation Variation (RAV)
  • Support for Forsyth-Edwards-Notation (FEN, http://de.wikipedia.org/wiki/Forsyth-Edwards-Notation)
• PgnWriter, formatter for PGN games.

• Bugfix: zero-length move text bug (IndexOutOfRange)
• Introduce MoveTextEntryList, a MoveEntry list which provides simplifed access to moves.
• Change type of Game.MoveText and RAVEntry.MoveText to MoveTextEntryList
• Add missing API doc
• Add support for frameworks: net40, net45, wp71
