Call an engine from BASIC?!

JBNielsen · Post by **JBNielsen** » Tue May 26, 2020 12:29 am

I am doing progress

.
These commands work:
SHELL "Stockfish go movetime 3000 >tempfile.txt"
SHELL "Stockfish bench 1 1 8 silver.epd >tempfile.txt"

But these do NOT work:
SHELL "Stockfish position startpos go movetime 3000 >tempfile.txt"
SHELL "Stockfish position fen rnbqkbnr/pppppppp/8/8/8/8/PPPPPPPP/RNBQKBNR b KQkq - 0 1 go movetime 3000 >tempfile.txt"
SHELL "Stockfish position startpos moves a2a3 go movetime 3000 >tempfile.txt"

As my input is a pgn-file, I would like this to work.
SHELL "Stockfish position startpos moves 1.e4 d6 2.d4 go movetime 3000 >tempfile.txt"
But it is probably outside the protocol

Use redirection from files. You are trying to put multiple commands on a single command line

Many years ago, Thomas McBurney, author of the chess engines Kanguruh and Minimax (both written in BASIC), sent me a chunk of BASIC code using pipes to communicate with an external program. Keep in mind that this code is for 32 bit Windows, and written in FreeBASIC, and would have to be adapted to 64 bit windows and QB64, but the general idea of using API calls to communicate remains the same.

Thank you very much!

Thanks; that helped a lot!

Code: Select all

position startpos moves f2f4 >tempfile.txt 
go movetime 3000
position fen rnbqkbnr/pppppppp/8/8/8/8/PPPPPPPP/RNBQKBNR w KQkq - 0 1
go movetime 3000
position startpos moves 1.e4 f5
go movetime 3000

But only the output from the first position is as I expected?!

Code: Select all

Make a file of Epd records.
In this case, let's call the file epd.epd
Suppose that this is what the file looks like:

Code: Select all

r2q1rk1/pp2bppp/2n1bn2/3pN1B1/2pP1P2/2N3P1/PP2P1BP/R2Q1RK1 b - -
rn1qk2r/p1p1bppp/1pb1pn2/3p2B1/Q1PP4/P1N2N2/1P2PPPP/R3KB1R w KQkq -
r1bq1rk1/pppn1pbp/3p1np1/4p3/3PP3/2PB1N2/PP1N1PPP/R1BQR1K1 b - -
rnbqk1nr/pp3ppp/2p5/3p4/1b1P4/2NB4/PPP2PPP/R1BQK1NR w KQkq -
r1bqk1nr/ppppbppp/8/n3p3/3PP3/2P2N2/P3BPPP/RNBQK2R b KQkq -

Now, make a second file callled run.par that looks like this:

Code: Select all

setoption name SyzygyPath value c:\chess\syzygy;
benchmark 8192 8 300003 c:\chess\analysis\epd.epd movetime
quit

You can run stockfish with the command:
c:\chess\analysis\stockfish < c:\chess\analysis\run.par

I have a special version of stockfish that logs the analysis directly to disk as SAN output for reprocessing.

Thanks; that might be a good path to follow.

Then I need to transform my pgn-games into epd-positions.
Such a function surely already exists....

Not quite sure you mention this version...
Would it be easier for me to use that version?
(but maybe harder to change engine some day; but that's not really a problem for me...)

When I have finished my project I would like to include an engine - all the project for free.

I have been away from programming for 6 years.
So I am also not sure what SAN output is...

I don't know if it would be easier because I do not know exactly what you are trying to do.

Oh, SAN is just short alg. notation

.
Yes that would be nice; much easier for the user to read.
(I thought SAN was some technical file-format or something like that...)

I would like to do this that I did 7 years ago:
http://talkchess.com/forum3/viewtopic.p ... 21#p483721

But it does not work any more.
Some of the improvements made for this in Winboard never ended up in the official version.
And fx Arena could not analyse several games in a pgn-file as a batch.

But I think I can make it now even in a single run seen from the users view:

A compiled BASIC-program:
First transform all pgn-games into epd-positions and analyse them:
SHELL "Stockfish <SFinput.bat >tempfile.txt"
Then convert the output to winboard-analyse-format and then format it with:
SHELL "StartDabbaba.bat >tempfile.txt" (this still works)
SHELL "edit DabbabaListPgnAnalyze.txt" (does not work)
