Crafty's - alternative move storage[pgn]

[jhaglund]

Dear Readers,

I am working on a new pgn generating fuction/program for Crafty.

Basically, I made two of each log_file(log.nnn), log_filename, log, logpath, etc., and put it with history_file(game.nnn) also.

I want to use something like this:

fprintf(pgn_file, "%s\n", searched_line);

Coming up with "searched_line" is trouble-some for me. Crafty's output && search are way to big for me to study.

I don't want it to be "best_search_line" that is displayed in the log.nnn. I need ALL the moves searched for every ply.

It has to be pretty simple though, I just cannot find or figure which variable(s)... to output to file.

Please help,

Joshua

Have you looked at "annotate.c" which probably has everything you need...

[jhaglund]

No, but thanks Bob for pointing me to "annotate.c". It does save me some time it looks like.

However, "annotate" reads stored files already in pgn format. This only stores the moves in the game.001... to "game.001.can

I would like to generate/store all the moves searched(evals) by Crafty in PGN format, with -N, N being all the nodes for every PV for every ply. I need the search tree-> stored in PGN format

annotate game.001 w 1 -.5 10 -N

to make it search all of them I doubled the first moves...
game.001

What I was thinking of was this:

1. annotate writes out all the headers for the PGN.

2. It also writes out each move as it is "played".

3. It also writes out analysis, enclosed in braces {} for each move that it disagrees with or for every move it told to do so, etc. It already is writing out the sort of stuff you want, you just need to modify it to behave exactly as you want probably without the "threshold" and such...

[jhaglund]

You are correct

It already is writing out the sort of stuff you want, you just need to modify it to behave exactly as you want probably without the "threshold" and such...

[jhaglund]

2. It also writes out each move as it is "played".

Could you point me to that variable please?

You should really have an index of all the variables and locations, in Crafty. It would be a great resource tool for educational purposes. It would be really helpful. Does someone need some extra credit?

Where is this "threshold" and such I need to modify?

It really isn't a "variable" as such. The tree->path[1] structure has the results of a search. All the moves, the depth, the number of moves in the PV, etc...

[jhaglund]

It really isn't a "variable" as such. The tree->path[1] structure has the results of a search. All the moves, the depth, the number of moves in the PV, etc...

How can I "print" them?

fprintf(pgn_file, " %s", tree->path); //incorrect

I figured it was tree-> something...

Even without looking at Crafty source code, I guess tree->path points to a structure that you must understand and then exploit.

[jhaglund]

Even without looking at Crafty source code, I guess tree->path points to a structure that you must understand and then exploit.

From the looks of things... it's too inter-connected with outputmove(...); or DisplayPV(...);...

Looks like I'd have to rewrite too much

fprintf(pgn_file, "%s \n", buffer); ... gives me a little more of what I was
looking for...

I think someone should rewrite Crafty into C++
