From: H.G. Muller Date: Sat, 14 Sep 2013 11:54:23 +0000 (+0200) Subject: Implement exclude-moves feature X-Git-Url: http://winboard.nl/cgi-bin?a=commitdiff_plain;h=796705fb0dd6391c4d0ad8a637eeefa405425bb0;p=bonanza.git Implement exclude-moves feature The WinBoard include and exclude commands are implemented to maintain an exclude_list of moves, which is then used during analyze mode in stead of the restraint.dat file to exclude root moves. The exclude_list contains moves in their internal encoding, which is now calculated as a side effect of the xboard -> CSA move conversion. --- diff --git a/proce.c b/proce.c index cfeabe1..50eae57 100644 --- a/proce.c +++ b/proce.c @@ -96,6 +96,7 @@ procedure( tree_t * restrict ptree ) char *start_pos, start_data[512]; // [HGM] undo: for remembering start position int move_list[1024], move_ptr; char analyze_mode; +int exclude_list[MAX_LEGAL_MOVES], all_moves[MAX_LEGAL_MOVES]; #ifdef XBOARD #define IF(X) else if(!strcmp(command, X)) @@ -103,11 +104,11 @@ char analyze_mode; int myTime, hisTime, movesPerSession, inc, plyNr; char xboard_mode; -void -xboard_to_CSA( tree_t * restrict ptree, char *in, char *out ) +int +xboard_to_CSA( tree_t * restrict ptree, char *in, char *out, int status ) { char fromX=in[0], fromY=in[1], toX=in[2], toY=in[3], promo=in[4]; - int piece=0; + int piece=0, bonanza_move=0; if(fromY == '@') { // drop (contains all info needed to convert it) if(fromX >= 'a') fromX += 'A' - 'a'; switch(fromX) { // encode piece @@ -119,21 +120,23 @@ xboard_to_CSA( tree_t * restrict ptree, char *in, char *out ) case 'B': piece = bishop; break; case 'R': piece = rook; break; } + bonanza_move = Drop2Move(piece) | To2Move( ('9' - toY)*9 + (toX - 'a') ); sprintf(out, "00%c%c%s", 'a'+'9'-toX, '1'+'9'-toY, astr_table_piece[piece]); } else { // board move (need to figure out moved piece) int from = ('9' - fromY)*9 + (fromX - 'a'); int flag = (promo == '+' ?
