The original Forsyth standard has been slightly extended for use with chess software by Steven Edwards with assistance from commentators on the Internet. The first four fields of the FEN specification are the same as the first four fields of the EPD specification.Ī text file composed exclusively of FEN data records should have a file name with the suffix ".fen".įEN is based on a 19th century standard for position recording designed by the Scotsman David Forsyth, a newspaper journalist. "Forsyth-Edwards Notation" is a standard for describing chess positions using the ASCII character set.Ī single FEN record uses one text line of variable length composed of six data fields.

However, unlike FEN, EPD is designed to be expandable by the addition of new operations that provide new functionality as needs arise. Like FEN, EPD can also be used for general position description. EPD was developed by John Stanback and Steven Edwards its first implementation is in Stanback's master strength chessplaying program Zarkov. The four fields of the EPD specification are the same as the first four fields of the FEN specification.Ī text file composed exclusively of EPD data records should have a file name with the suffix ".epd".ĮPD is based in part on the earlier FEN standard it has added extensions for use with opening library preparation and also for general data and command interchange among advanced chess programs.

It is also intended for the representation of portable opening library repositories.Ī single EPD uses one text line of variable length composed of four data field followed by zero or more operations. It is intended for data and command interchange among chessplaying programs. "Extended Position Description" is a standard for describing chess positions along with an extended set of structured attribute values using the ASCII character set. Returns an array of strings that represent the conversion of game text into positional shorthand, one entry for each move made in the game. The returned values are: $w - boolean, white to move? $Kc - boolean, has white castled king side? $Qc - boolean, has white castled queen side? $kc - boolean, has black castled king side? $qc - boolean, has black castled queen side? %board - hash board, keys are algebraic square names, values are occupying piece. If given an EPD string, set board accordingly. Provides access to the 'board' with the current epd postition set up. Useful for conversions to other forms of notation i.e. Returns an array of hashes that contain move information. NOTE: This routine is deprecated in favor of epdTaxonomy and will at some point be removed.

The 'ToDo' list also mentions the possibility of extending the databases, although that might come in the form of a 'How To' rather than any code solution. On demand other formats (the current is JSON) may be implemented. 'Opening' Traditional Opening name in English.Īt the moment, this routine depends on three database files installed along with the module. Allowed codes are: 'ECO' from The Encyclopedia of Chess Openings. Print join("\n",epdTaxonomy(moves => => 1,astags => 1)),"\n" ĭetermines the requested code given a list of epd strings in reverse order. Print join("\n",epdstr(epd => $position,type => 'latex')) My $position = 'rnbqkb1r/ppp1pppp/5n2/3P4/8/8/PPPP1PPP/RNBQKBNR w KQkq -' My $pgn = new Chess::PGN::Parse($ARGV) or die "Can't open $ARGV: $!\n" You can then save the position into a database just like any other game."Ĭhess::PGN::EPD attempts to bring ease and convenience to its users programmatically by providing a set of functions that manipulate EPD text. Click "OK" and you'll now have an "Enter new game" window with the proper board position on it taken from the EPD file.

You'll instantly see the position appear on the board in the "Setup position" window. Then open ChessBase, go to the Game menu, select "Setup position", and click the button marked "Paste FEN". Just highlight the EPD line from a post or web page and hit CRTL-C on your keyboard. There's a quick, easy way to copy and paste these board descriptions into ChessBase or any of our playing programs (Fritz, Hiarcs, Nimzo, Junior). You'll frequently see posts to Usenet chess newsgroups or other message boards containing these EPD positions. This was designed as a way for chess players and chess programs to pass board positions back and forth for analysis. For example, here's what the board position after 1.e4 looks like in EPD format: rnbqkbnr/pppppppp/8/8/4P3/8/PPPP1PPP/RNBQKBNR b KQkq e3 0 1

One of these is called EPD (Extended Position Description) format it's just a convenient way to provide a board position (rather than a full game) in an ASCII text notation. "There's a lot of chess information available on the Internet in a variety of formats.
