Multiple options for engine running

[st4ck3]

Hi,

This library is great, congratulations.

I am trying to expand the example about UCI options to send two options to the engine:

package main

import (
	"fmt"
	"time"
    "reflect"
	"github.com/notnil/chess"
	"github.com/notnil/chess/uci"
)

func main() {
	// set up engine to use stockfish exe
	eng, err := uci.New("/home/myuser/Documents/chess/engines/stockfish/Stockfish/src/stockfish")
	if err != nil {
		panic(err)
	}
	defer eng.Close()
	// initialize uci with new game
	if err := eng.Run(uci.CmdUCI, uci.CmdIsReady, uci.CmdUCINewGame); err != nil {
		panic(err)
	}
	
	  
        var setOpt [2]uci.CmdSetOption 
        setOpt[0] = uci.CmdSetOption{Name: "Syzygy50MoveRule", Value: "False"}
	
       setOpt[1] = uci.CmdSetOption{Name: "Hash", Value: "1024"}
	// This line works!
       //setOpt := uci.CmdSetOption{Name: "Hash", Value: "1024"}

    fmt.Println(reflect.TypeOf(eng))
    fmt.Println(reflect.TypeOf(setOpt))
	fmt.Println(setOpt)
	// have stockfish play speed chess against itself (10 msec per move)
	game := chess.NewGame()
    
	for game.Outcome() == chess.NoOutcome {
		cmdPos := uci.CmdPosition{Position: game.Position()}
		cmdGo := uci.CmdGo{MoveTime: time.Second / 100}
		if err := eng.Run(cmdPos, cmdGo, setOpt); err != nil {
			panic(err)
		}
		move := eng.SearchResults().BestMove
		if err := game.Move(move); err != nil {
			panic(err)
		}
        
	}
	fmt.Println(game.String())

I have substituted

var setOpt [2]uci.CmdSetOption

with

setOpt[0] = uci.CmdSetOption{Name: "Syzygy50MoveRule", Value: "False"}
setOpt[1] = uci.CmdSetOption{Name: "Hash", Value: "1024"}

I get following error message:

./hello.go:40:36: cannot use setOpt (variable of type [2]uci.CmdSetOption) as uci.Cmd value in argument to eng.Run: [2]uci.CmdSetOption does not implement uci.Cmd (missing method ProcessResponse)

Any help would be greatly appreciated!

Thanks in advance!

Hi,

I found out the answer:

    setOpt  := uci.CmdSetOption{Name: "Syzygy50MoveRule", Value: "False"}
    setOpt1 := uci.CmdSetOption{Name: "Hash", Value: "1024"}

	if err := eng.Run(cmdPos, cmdGo, setOpt, setOpt1); err != nil {
		panic(err)
	}
