go-atari-models, v1.7

The library that implements checking and generating of Atari Go moves.

Encoding of positions and boards in Smart Game Format.

Change Log

encoding in Smart Game Format:
- parsing:
  - of a stone color;
  - of a coordinate;
  - of a position;
  - of a board size;
  - of a move;
  - of a board;
- serialization:
  - of a stone color;
  - of a coordinate;
  - of a position.

Features

representing the board as an associative array of stones with their positions as keys;
immutable applicating moves to the board via copying the latter;
checkings of moves:
- taking into account self-capture;
generating of moves via filtering from all possible ones:
- pseudolegal moves;
- legal moves (with additional checking for captures);

Examples

sgf.DecodeBoard():

package main

import (
    "fmt"

    models "github.com/thewizardplusplus/go-atari-models"
    "github.com/thewizardplusplus/go-atari-models/encoding/sgf"
)

func main() {
    board, _ := sgf.DecodeBoard("(;FF[4]SZ[7:9]GN[test];B[aa](;W[gi]N[test]))")

    var moves []models.Move
    for _, point := range board.Size().Points() {
        if color, ok := board.Stone(point); ok {
            moves = append(moves, models.Move{Color: color, Point: point})
        }
    }

    fmt.Printf("%+v\n", board.Size())
    fmt.Printf("%+v\n", moves)

    // Output:
    // {Width:7 Height:9}
    // [{Color:0 Point:{Column:0 Row:0}} {Color:1 Point:{Column:6 Row:8}}]
}
