ParseMove and Highlight thus no longer have to generate it, and generation is moved to the top of the main loop, and only done when the list does not exist yet. The list is discarded as soon as we execute a command that changes the game position. --- diff --git a/hachu.c b/hachu.c index a81f25f..2b89d21 100644 --- a/hachu.c +++ b/hachu.c @@ -2091,7 +2091,7 @@ MapFromScratch(attacks); postThinking--; repCnt = 0; tlim1 = tlim2 = 1e8; msp = 0; Search(-INF-1, INF+1, 0, 1, sup1 & ~PROMOTE, sup2); postThinking++; - listStart = retFirst; listEnd = retMSP; + listStart = retFirst; listEnd = msp = retMSP; } MOVE @@ -2116,7 +2116,7 @@ ParseMove (char *moveText) ret = f<> SQLEN & SQUARE)) break; // any null move matches @@@@ @@ -2157,7 +2157,7 @@ Highlight(char *coords) char b[BSIZE], buf[2000], *q; for(i=0; i>SQLEN & SQUARE)) { int t = moveStack[i] & SQUARE; @@ -2259,6 +2259,8 @@ printf("# setup done");fflush(stdout); fflush(stdout); // make sure everything is printed before we do something that might take time + if(listEnd == 0) ListMoves(); // always maintain a list of legal moves in root position + if(stm == engineSide) { // if it is the engine's turn to move, set it thinking, and let it move pboard(board); @@ -2285,6 +2287,7 @@ pboard(board); stm = MakeMove2(stm, move); // assumes MakeMove returns new side to move gameMove[moveNr++] = move; // remember game printf("move %s\n", MoveToText(move, 1)); + listEnd = 0; } } @@ -2380,11 +2383,12 @@ pboard(board); if(comp) PrintResult(stm, -INF); // against computer: claim } else { stm = MakeMove2(stm, move); - ponderMove = INVALID; + ponderMove = INVALID; listEnd = 0; gameMove[moveNr++] = move; // remember game } continue; } + listEnd = 0; if(!strcmp(command, "new")) { engineSide = BLACK; Init(V_CHESS); stm = Setup2(NULL); maxDepth = MAXPLY; randomize = OFF; curVarNr = comp = 0; continue;
