CookieCat retouched

[Roland Chastain]

Hello!

Some days ago I discovered CookieCat, the Pascal chess program by Steven Edwards.

I began to study it and to dream of what I could do with it: make a GUI for it, write an UCI or a WinBoard interface...

I noticed that the program had a memory leak. With a little patience, I was lucky enough to find the origin of the memory leak and to fix it. So I thought that it would be a good idea to share the modified source code.

Here is where you can get it:
https://github.com/rchastain/cookiecat

As I said, I would like in the future to make some more important modifications. One of my wishes for 2020 is to learn the WinBoard protocol, so why not a WinBoard interface for CookieCat?

In his to do list, the author speaks of a "SCI (Simple Chess Interface) command processor". I asked to Google what it is and found nothing. Have you ever heard of that protocol?

Regards.

Roland

Nice of you to carry on Steven's legacy.

CECP support would be very nice, we could even see CookieCat in rating lists.
I'm sure hgm can answer any of your questions regarding the xboard protocol.

I don't know about SCI, perhaps something internal to CookieCat?

Good luck with the project.

[Guenther]

bump... ;)

[Guenther]

Finally it happened :)

CookieCat 2012.10.10 rc1 'released' a few days ago
https://github.com/En-En-Code/cookiecat

Compilations + some xboard-interface and time management added by user 'En-En-Code'
(thanks also to Roland, who had fixed a memory leak already before)

[Dann Corbit]

nice!

Thanks.

That was under Arena. No problem under Cute Chess so far.

The reason under Arena, allegedly, was receiving an 'unknown command'. Here is an excerpt from its debug:

I think san requires a check symbol in the notation, which is missing here.

https://www.gnu.org/software/xboard/engine-intf.html

Beginning in protocol version 2, you can use the feature command to select SAN (standard algebraic notation) instead; for example, e4, Nf3, exd5, Bxf7+, Qxf7#, e8=Q, O-O, or P@h3. Note that the last form, P@h3, is a extension to the PGN standard's definition of SAN, which does not support bughouse or crazyhouse.

http://hgm.nubati.net/newspecs.html

san (0) Requests sending of the moves to the engine as SAN instead of long algebraic. Using SAN is not recommended, especially in variants, and GUIs are allowed to refrain from using SAN even when they accepted the san feature requesting it, when SAN would be problematic.

The last part from newspecs sounds a bit confusing, but I see no reason to refrain from san for Arena as this was no variant game
and CookieCat clearly sent san=1.
BTW I guess it was set up as protover 2 engine in Arena? May be it works with WB2UCI then?
