badukjs is a JavaScript library for the game of Go.

It includes the following properties:

• Baduk.SGF: parsing of SGF files, allows performing operations on the corresponding board and outputting SGF files again.
• Baduk.Board: managing a Go board, including the rules of the game, and computing the score. (Ongoing work.)
• Baduk.Gonvnet: running a Go bot.

var sgf = new Baduk.SGF();
sgf.parse(stringOfSGFContent, {error: function(err) { console.error(err); }});
// List of {sequence, gameTrees}.
// `sequence` is a list of objects mapping SGF properties to their values.
// For instance, for a move: {B: [16, 3]} (17th intersection from the left, 3rd
// from the top).
// `gameTrees` is a list of {sequence, gameTrees}.
sgf.content

sgf.step();  // Performs the first move on sgf.board.
sgf.run();   // Perform all the game from the SGF on sgf.board.
sgf.countMoves();  // Number of moves in the game.
sgf.reset(); // Reset sgf.board to the starting position.

Binaries

• ./bin/print-sgf.js: reads an SGF file from stdin, outputs a UTF-8 representation of the result. If passed with --steps, outputs a representation of the board for every move.
• ./bin/sgf2json.js: converts SGF to a JSON representation.
• ./bin/go.js: plays a game. Defaults to it being played by stdin. It can be set to read inputs from a file, a process (--black="gnugo --color white --mode ascii) or from an ai (--white=probaduk:../tree.json).
