Decompile to C# in SB-Prime - Checkbox Console App

Tue, 15 Oct 2024 16:21:27 +0000

The Chess Engine SB_Scout is a mixed application with a text window and a graphics window. (PDVF923.000)
As it is not a pure console application, I have disabled the checkbox "Export as Console App".
Is the following error related to this or is there another cause?

SmallBasic Open Edition

Sun, 13 Oct 2024 16:41:52 +0000

Hi,

This project (SmallBasic Open Edition) is part of a larger whole, where the goal is to recreate Microsoft SmallBasic, at least in its main features.

The first phase of the project, which is exactly this, is to create the same classes as in SmallBasic: Text, Math, GraphicsWindow, and so on. The project is mostly complete, although types for variables, some small tests, and so on are still required.

Note: The classes Array, Flickr, and Dictionary have not been created.

Array is missing because I have not yet decided on the final way the future compiler will handle arrays. I have a couple of different solutions for this, but I haven’t had time to decide yet.

Flickr is missing because I am simply not very familiar with this service, and their API is completely unknown to me.

Dictionary is a class I’m not sure if I want to spend time on, at least not personally.

Unlike the original SmallBasic, Open Edition converts SmallBasic code into the C# programming language and compiles it afterward. This brings significant advantages in terms of memory management, speed, and extensibility.

Variables will function mostly the same way as in the original SmallBasic. This is made possible by C#’s dynamic. However, the idea is that variables will require a suffix of "$" at the end of their names. Not only does this make the programs easier to compile, but I also believe it helps distinguish variables and makes coding a bit easier.

The program that tokenizes and converts SmallBasic code into C# is also mostly done. However, at the moment, it's more like a pile of sticks rather than a well-designed and structured program, so its release will be more appropriate at a later time.

Example SmallBasic program:

Code:
' Example Smallbasic program

x$ = 1

y$ = 2

c$ = "Foo"

TextWindow.WriteLine(x$ + y$ + c$)

SayHello()

Goto MyLabel:

TextWindow.WriteLine("I'm never printed.")

MyLabel:

Program.End()

Sub SayHello

    TextWindow.WriteLine("Hello")

EndSub

Converted to C#:

Code:
// Converted as C#

namespace SmallBasicOpenEditionDll

{

    public static class SB_Program

    {

        // Declare dynamic variables (similar to Smallbasic's dynamic typing)

        public static dynamic x = 1;

        public static dynamic y = 2;

        public static dynamic c = "Foo";

        // Entry point of the program

        public static void Main()

        {

            // Equivalent of TextWindow.WriteLine(x$ + y$ + c$)

            TextWindow.WriteLine(x + y + c);

            // Call the method SayHello()

            SayHello();

            // This line will not be executed

            Goto MyLabel:

            TextWindow.WriteLine("I'm never printed.");

            MyLabel:

            Program.End();

        }

        // The equivalent of SmallBasic's subroutine 'SayHello'

        public static void SayHello()

        {

            TextWindow.WriteLine("Hello");

        }

    }

}

Note: I work with this while I am working with two job's and such, so this will not move forward in fast speed. Help is appreciated here. Let me know

Updating SB

Mon, 09 Sep 2024 12:31:18 +0000

Today I got an idea why someone can't help in updating SB.
We have a community here so any good csharp developer can do this but not me.
I could help in writing standard library for SB.
Making it a high-level programing language.
I have some goals that can be in SB
Addition of function like struct new keywords.
And large standard library seperate dll.
Many csharp functionality.
As I thought sb just use csc.exe to compile a small basic program after converting it to csharp am I right????.

Hii Litdev
Today I Tried To Download Small Basic Repo From Github.
I Updated Its .csproj File As You Said Before.

Helpful YouTube videos (UCI-Interface for Chess-Engines)

Wed, 22 May 2024 20:36:11 +0000

The discussion of the AI championship with a playing field and separate engines reminded me of the chess engine championships of the last few decades. The ranking is determined from countless games that the engines play against each other. This is done automatically via defined interfaces (e.g. UCI interface).
My attempts to access this interface with Small Basic failed because I didn't know how Small Basic used the stdio interface.
So I looked for a C# chess engine that was as simple as possible and then wrote a Small Basic program using the source code that could at least access the UCI interface.
Searching on github I found the following video series that shows how an unknown interface can be accessed and operated using debug outputs.

https://www.youtube.com/playlist?list=PL6vJSkTaZuBtTokp8-gnTsP39GCaRS3du

The video series consists of four episodes, of which I have completed the first one and the others will probably take some time.

Definition UCI Interface: https://en.wikipedia.org/wiki/Universal_Chess_Interface

Chess program that can communicate with chess engines: https://cutechess.com/

Episode 1 : Hello World

The program CS_UCI was written in Visual Studio 2017.
It is a console application with the target framework .NET 4.5.2

Code:
using System;

using System.Collections.Generic;

using System.Linq;

using System.Text;

using System.Threading.Tasks;

namespace CS_UCI

{

    class Program

    {

        static void Main(string[] args)

        {

            string[] Move = { "e7e5", "a7a6", "d7d6", "b7b5", "g8f6", "g7g6", "h7h5", "f8g7", "b8c6" };

            int Movecount = 0;

            while (true)

            {

                //remove leading & trailing whitecases and split using ' ' as delimiter

                string[] tokens = Console.ReadLine().Trim().Split(' ');

                //string   command = Console.ReadLine().Split(' ')[0];

                switch (tokens [0])

                {

                    case "uci":

                        Console.WriteLine("uciok");

                        break;

                    case "isready":

                        Console.WriteLine("readyok");

                        break;

                    case "go":

                        Console.WriteLine("bestmove "+ Move[Movecount]);

                        // Console.WriteLine(Move[Movecount]);

                        Movecount = Movecount + 1;

                        if (Move.Length <= Movecount)

                            { Movecount = Movecount - 1 ; }

                        break;

                    case "position":

                        // Board;

                        break;

                    default:

                        Console.WriteLine("info " +  tokens[0].ToString());

                        break;

                }

            }

        }

    }

}

After starting Cute Chess, the exe file must be defined as the engine via Settings.

Using New, you can choose any engine for white (stockfish, Dragon, etc.) or you can play yourself.

CS_UCI can now be selected for black.

The dummy moves provided for black should be enough for a few moves.

Debugging with dnSpy

Mon, 20 May 2024 14:46:09 +0000

I have been playing with dnSpy and find it very useful for debugging Small Basic programs. You can get it from https://github.com/dnSpy/dnSpy/releases - (download dnSpy-net-win64.zip, unblock, extract from zip and run dnSpy.exe, then File->Open... a compiled Small Basic exe and get a professional debugging experience!)

It allows me to debug into SmallBasicLibrary.dll as well as extensions like LitDev.dll. This is very useful for me to test things, but maybe also for Small Basic users to see how things are done in extension code.
