From 2ee09cd4d5abd21ff6f1072bfba123c1498bef23 Mon Sep 17 00:00:00 2001 From: H.G.Muller Date: Tue, 9 Feb 2016 10:59:31 +0100 Subject: [PATCH] Allow promotion on two-leg move After a second-leg of a SAN move the parser now checks for apromotion suffix, and if any is found this is used by ParseOneMove / LoadGameOneMove to set the promoChar. In converting to SAN for the parseList the promoChar is now appended to the second leg, rather than the first, and the Edit Book window will also show it. The promochar is written behind the kill square in the moveList, and when sending the move there to the engine it is appended to the second move of the multi-move pair. --- backend.c | 21 ++++++++++++++------- 1 files changed, 14 insertions(+), 7 deletions(-) diff --git a/backend.c b/backend.c index a4f7852..bc6ec28 100644 --- a/backend.c +++ b/backend.c @@ -5145,16 +5145,18 @@ SendMoveToProgram (int moveNum, ChessProgramState *cps) } else if(moveList[moveNum][4] == ';') { // [HGM] lion: move is double-step over intermediate square char *m = moveList[moveNum]; + static char c[2]; + *c = m[7]; // promoChar if((boards[moveNum][m[6]-ONE][m[5]-AAA] < BlackPawn) == (boards[moveNum][m[1]-ONE][m[0]-AAA] < BlackPawn)) // move is kludge to indicate castling snprintf(buf, MSG_SIZ, "%c%d%c%d,%c%d%c%d\n", m[0], m[1] - '0', // convert to two moves m[2], m[3] - '0', m[5], m[6] - '0', m[2] + (m[0] > m[5] ? 1 : -1), m[3] - '0'); else - snprintf(buf, MSG_SIZ, "%c%d%c%d,%c%d%c%d\n", m[0], m[1] - '0', // convert to two moves + snprintf(buf, MSG_SIZ, "%c%d%c%d,%c%d%c%d%s\n", m[0], m[1] - '0', // convert to two moves m[5], m[6] - '0', m[5], m[6] - '0', - m[2], m[3] - '0'); + m[2], m[3] - '0', c); SendToProgram(buf, cps); } else if(BOARD_HEIGHT > 10) { // [HGM] big: convert ranks to double-digit where needed @@ -5358,6 +5360,10 @@ CoordsToComputerAlgebraic (int rf, int ff, int rt, int ft, char promoChar, char } else { sprintf(move, "%c%c%c%c%c\n", AAA + ff, ONE + rf, AAA + ft, ONE + rt, promoChar); + if(killX >= 0 && killY >= 0) { + sprintf(move+4, ";%c%c\n", AAA + killX, ONE + killY); + if(kill2X >= 0 && kill2Y >= 0) sprintf(move+7, "%c%c%c\n", AAA + killX, ONE + killY, promoChar); + } } } } @@ -5556,7 +5562,7 @@ ParseOneMove (char *move, int moveNum, ChessMove *moveType, int *fromX, int *fro *toX = currentMoveString[2] - AAA; *toY = currentMoveString[3] - ONE; *promoChar = currentMoveString[4]; - if(*promoChar == ';') *promoChar = NULLCHAR; + if(*promoChar == ';') *promoChar = currentMoveString[7]; if (*fromX < BOARD_LEFT || *fromX >= BOARD_RGHT || *fromY < 0 || *fromY >= BOARD_HEIGHT || *toX < BOARD_LEFT || *toX >= BOARD_RGHT || *toY < 0 || *toY >= BOARD_HEIGHT) { if (appData.debugMode) { @@ -7141,7 +7147,8 @@ UserMoveEvent(int fromX, int fromY, int toX, int toY, int promoChar) if(addToBookFlag) { // adding moves to book char buf[MSG_SIZ], move[MSG_SIZ]; CoordsToAlgebraic(boards[currentMove], PosFlags(currentMove), fromY, fromX, toY, toX, promoChar, move); - if(killX >= 0) snprintf(move, MSG_SIZ, "%c%dx%c%d-%c%d", fromX + AAA, fromY + ONE - '0', killX + AAA, killY + ONE - '0', toX + AAA, toY + ONE - '0'); + if(killX >= 0) snprintf(move, MSG_SIZ, "%c%dx%c%d-%c%d%c", fromX + AAA, fromY + ONE - '0', + killX + AAA, killY + ONE - '0', toX + AAA, toY + ONE - '0', promoChar); snprintf(buf, MSG_SIZ, " 0.0%% 1 %s\n", move); AddBookMove(buf); addToBookFlag = FALSE; @@ -10459,10 +10466,10 @@ MakeMove (int fromX, int fromY, int toX, int toY, int promoChar) if(killX >= 0 && killY >= 0) x = killX, y = killY; // [HGM] lion: make SAN move to intermediate square, if there is one (void) CoordsToAlgebraic(boards[forwardMostMove], PosFlags(forwardMostMove), - fromY, fromX, y, x, promoChar, + fromY, fromX, y, x, (killX < 0)*promoChar, s); if(killX >= 0 && killY >= 0) - sprintf(s + strlen(s), "%c%c%d", p == EmptySquare || toX == fromX && toY == fromY ?
