go-chess-models, v1.6

The library that implements checking and generating of chess moves.

Working with Forsyth–Edwards Notation for positions and moves, extending moves checkings and refactoring.

Change Log

• Forsyth–Edwards Notation:
  • parsing:
    • of a position;
    • of a move;
  • serialization:
    • of a position;
    • of a move;
• extending universal moves checkings;
• refactoring.

Features

• representing the board as an associative array of pieces with their positions as keys;
• immutable applicating moves to the board via copying the latter;
• checkings of moves:
  • universal;
  • individual for all types of pieces;
• generating moves via filtering from all possible ones;
• using an abstraction of a piece;
• Forsyth–Edwards Notation:
  • parsing:
    • of a position;
    • of a move;
    • of a piece kind;
    • of a piece color;
    • of a board;
  • serialization:
    • of a position;
    • of a move;
    • of a piece kind;
    • of a piece color;
    • of a board.

Examples

uci.DecodePosition():

package main

import (
    "fmt"

    "github.com/thewizardplusplus/go-chess-models/encoding/uci"
)

func main() {
    position, _ := uci.DecodePosition("c3")
    fmt.Printf("%+v\n", position)

    // Output: {File:2 Rank:2}
}

uci.EncodePosition():

package main

import (
    "fmt"

    models "github.com/thewizardplusplus/go-chess-models"
    "github.com/thewizardplusplus/go-chess-models/encoding/uci"
)

func main() {
    position := uci.EncodePosition(models.Position{File: 2, Rank: 2})
    fmt.Printf("%v\n", position)

    // Output: c3
}

uci.DecodeMove():

package main

import (
    "fmt"

    "github.com/thewizardplusplus/go-chess-models/encoding/uci"
)

func main() {
    move, _ := uci.DecodeMove("d4c3")
    fmt.Printf("%+v\n", move)

    // Output: {Start:{File:3 Rank:3} Finish:{File:2 Rank:2}}
}

uci.EncodeMove():

package main

import (
    "fmt"

    models "github.com/thewizardplusplus/go-chess-models"
    "github.com/thewizardplusplus/go-chess-models/encoding/uci"
)

func main() {
    move := uci.EncodeMove(models.Move{
        Start:  models.Position{File: 3, Rank: 3},
        Finish: models.Position{File: 2, Rank: 2},
    })
    fmt.Printf("%v\n", move)

    // Output: d4c3
}
