SB Forms extension |

Looking through some of the old SB forum files I came accross one using Gungan's SB Forms extension, ZQX928. I added this extension to Extension Manager in SB-Prime.
If you come across any other fun extensions from the past and they exist in some form I can try to add them.

UCI Chess Engine |

After finding out how to access the UCI interface with the help of an introductory video, it is now possible to write a chess engine with Small Basic that can be integrated into chess programs.
The C# videos and further information can be found in the following thread: https://litdev.uk/mybb/showthread.php?tid=74
But there is still a long way to go to the first usable engine.
The 4 episodes of the C# video tutorial must be implemented in Small Basic and in C# programs.
Episode 1: Hello World
Code: 'Position Textwindow
TextWindow.Left = Desktop.Width/2+1
TextWindow.Top = Desktop.Height/2+200
'Movelist for black
Move[1] = "bestmove e7e5"
Move[2] = "bestmove a7a6"
Move[3] = "bestmove b7b5"
Move[4] = "bestmove g8f6"
Move[5] = "bestmove g7g6"
Move[6] = "bestmove h7h5"
Move[7] = "bestmove f8g7"
Move[8] = "bestmove b8c6"
Movecount = 1
'LDTextWindow.Hide()
LDTextWindow.UpdateShowHide = "False"
LDTextWindow.Minimise()
While ("True")
'TextWindow.PauseIfVisible()
commandline = TextWindow.Read()
command = LDText.Split(commandline," ")
if(command[1] = "uci") Then
TextWindow.WriteLine("uciok")
ElseIf(command[1] = "isready") Then
TextWindow.WriteLine("readyok")
ElseIf(command[1] = "position") Then
'Board Update
elseif(command[1] = "go") Then
'TextWindow.WriteLine("bestmove e7e5")
TextWindow.WriteLine(Move[Movecount])
Movecount = Movecount + 1
Else
TextWindow.WriteLine("info string "+ commandline)
endif
Program.Delay(7)
EndWhile
Integrating the exe file as an engine into a chess program is described in the C# thread and in the videos.
What is also annoying is that the text window cannot be hidden and it has no content.
But since it can be moved to the side, it is still acceptable.
Update:
With the features LDTextWindow.UpdateShowHide = "False" and LDTextWindow.Minimise() the text window can be minimized to the taskbar.
This requires the Litdev extension 1.2.28.0 or higher. Alternatively, the two lines can be commented out and the text window will appear on the screen.
Note:
If the SB_UCI.exe engine is distributed or copied to another directory, the DLLs Litdev.dll and SmallBasicLibrary.dll must also be included!

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

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.
The corresponding Small Basic program is in Thread: https://litdev.uk/mybb/showthread.php?tid=75

Debugging with dnSpy |

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.
