Re: [gnugo-devel] extract fuseki

[Stuart A. Yeates]

Hello Ben

I think i see the problem. Could you try

extract_fuseki sgflist 19 50 1000 10 1 0 2 5 1
extract_fuseki sgflist 19 50 1000 0 1 0 2 5 1

and let us know whether either of these works? It may not do exactly
do exactly what you want, but conformation that it works to a first
approximation tells us where the problem is.

I think there's a bug (a difference between the command line options
reported and tested. Compare:

handicap:  0 - no handicap, 1 - any game, 2-9 - two to nine handicap stones
           10 any handicap game

and

    /* only specific handicap games */
    if (handicap_value != 10 && handicap != handicap_value) {
      if (WARN)
        fprintf(stderr,
                "Sgf file %s has wrong number of handicap stones %d\n",
                sgfname, handicap);
      return 0;
    }

I think the code should read:

    /* only specific handicap games */
    if (handicap_value != 10 && handicap_value != 1 && handicap !=
handicap_value) {
      if (WARN)
        fprintf(stderr,
                "Sgf file %s has wrong number of handicap stones %d\n",
                sgfname, handicap);
      return 0;
    }

But then I'm new to this code.

cheers
stuart
