These can be used by anything that * wants to display this information to the user (e.g. about dialog). * * Note: it would be very nice if we could instead of (or in addition to) the * build date present a date which corresponds to the date our source files * were last changed. To understand the difference, imagine that a user * makes a checkout of CVS on January 1, then after a week compiles it * (e.g. after doing a 'make clean'). The build date then will say January 8 * even though the files were last changed on January 1. * * Another problem is that __DATE__/__TIME__ depend on the local time zone. * * It's clear that such a "last changed" date would be much more useful to us * for feedback purposes. After all, when somebody files a bug report, we * don't care about the build date, we want to know which date their checkout * was made. This is even more important now since anon CVS lags a few * days behind developer CVS. * * So, how could we implement this? At least on unix systems, a special script * could do it. Basically, that script would run over all .cpp/.h files and * parse the CVS 'Header' keyword we have in our file headers. * That line contains a date/time in GMT. Now, the script just has to collect * all these times and find the latest. This time then would be inserted into * a header file or so (common/date.h ?) which engine.cpp then could * include and put into a global variable analog to gScummVMBuildDate. * * Drawback: scanning all source/header files will be rather slow. Also, this * only works on systems which can run powerful enough scripts (so I guess * Visual C++ would be out of the game here? don't know VC enough to be sure). * * Another approach would be to somehow get CVS to update a global file * (e.g. LAST_CHANGED) whenever any checkins are made. That would be * faster and work w/o much "logic" on the client side, in particular no * scripts have to be run. The problem with this is that I am not even * sure it's actually possible! Modifying files during commit time is trivial * to setup, but I have no idea if/how one can also change files which are not * currently being commit'ed. */ const char *gScummVMVersion = "0.5.3cvs"; const char *gScummVMBuildDate = __DATE__ " " __TIME__; const char *gScummVMFullVersion = "ScummVM 0.5.3cvs (" __DATE__ " " __TIME__ ")"; /* FIXME - BIG HACK for MidiEmu */ OSystem *g_system = 0; Engine *g_engine = 0; Engine::Engine(GameDetector *detector, OSystem *syst) : _system(syst) { g_engine = this; _mixer = new SoundMixer(); _gameDataPath = detector->_gameDataPath; g_system = _system; // FIXME - BIG HACK for MidiEmu _timer = new Timer(this); } Engine::~Engine() { delete _mixer; delete _timer; } const char *Engine::getSavePath() const { const char *dir = NULL; #ifdef _WIN32_WCE dir = _gameDataPath; #elif defined(__PALM_OS__) dir = SCUMMVM_SAVEPATH; #else #if !defined(MACOS_CARBON) dir = getenv("SCUMMVM_SAVEPATH"); #endif // If SCUMMVM_SAVEPATH was not specified, try to use game specific savepath from config if (!dir || dir[0] == 0) dir = g_config->get("savepath"); // If SCUMMVM_SAVEPATH was not specified, try to use general path from config if (!dir || dir[0] == 0) dir = g_config->get("savepath", "scummvm"); // If no save path was specified, use no directory prefix if (dir == NULL) dir = ""; #endif return dir; } Engine *Engine::createFromDetector(GameDetector *detector, OSystem *syst) { Engine *engine = NULL; #ifndef DISABLE_SCUMM if (detector->_game.id >= GID_SCUMM_FIRST && detector->_game.id <= GID_SCUMM_LAST) { // Some kind of Scumm game engine = Engine_SCUMM_create(detector, syst); } #endif #ifndef DISABLE_SIMON if (detector->_game.id >= GID_SIMON_FIRST && detector->_game.id <= GID_SIMON_LAST) { // Simon the Sorcerer engine = Engine_SIMON_create(detector, syst); } #endif #ifndef DISABLE_SKY if (detector->_game.id >= GID_SKY_FIRST && detector->_game.id <= GID_SKY_LAST) { // Beneath a Steel Sky engine = Engine_SKY_create(detector, syst); } #endif #ifndef DISABLE_SWORD2 if (detector->_game.id >= GID_SWORD2_FIRST && detector->_game.id <= GID_SWORD2_LAST) { // Broken Sword 2 engine = Engine_SWORD2_create(detector, syst); } #endif return engine; } void NORETURN CDECL error(const char *s, ...) { #ifdef __PALM_OS__ char buf_input[256]; // 1024 is too big overflow the stack char buf_output[256]; #else char buf_input[1024]; char buf_output[1024]; #endif va_list va; va_start(va, s); vsprintf(buf_input, s, va); va_end(va); if (g_engine) { g_engine->errorString(buf_input, buf_output); } else { strcpy(buf_output, buf_input); } #ifdef __GP32__ //ph0x FIXME? printf("ERROR: %s\n", buf_output); #else fprintf(stderr, "%s!\n", buf_output); #endif #if defined( USE_WINDBG ) #if defined( _WIN32_WCE ) TCHAR buf_output_unicode[1024]; MultiByteToWideChar(CP_ACP, 0, buf_output, strlen(buf_output) + 1, buf_output_unicode, sizeof(buf_output_unicode)); OutputDebugString(buf_output_unicode); #else OutputDebugString(buf_output); #endif #endif #if defined ( _WIN32_WCE ) drawError(buf_output); #endif #ifdef __PALM_OS__ PalmFatalError(buf_output); #endif // Finally exit. quit() will terminate the program if g_system iss present if (g_system) g_system->quit(); exit(1); } void CDECL warning(const char *s, ...) { #ifdef __PALM_OS__ char buf[256]; // 1024 is too big overflow the stack #else char buf[1024]; #endif va_list va; va_start(va, s); vsprintf(buf, s, va); va_end(va); #ifdef __GP32__ //ph0x FIXME: implement fprint? printf("WARNING: %s\n", buf); #else fprintf(stderr, "WARNING: %s!\n", buf); #endif #if defined( USE_WINDBG ) strcat(buf, "\n"); #if defined( _WIN32_WCE ) TCHAR buf_unicode[1024]; MultiByteToWideChar(CP_ACP, 0, buf, strlen(buf) + 1, buf_unicode, sizeof(buf_unicode)); OutputDebugString(buf_unicode); #else OutputDebugString(buf); #endif #endif } uint16 _debugLevel = 1; void CDECL debug(int level, const char *s, ...) { #ifdef __PALM_OS__ char buf[256]; // 1024 is too big overflow the stack #else char buf[1024]; #endif va_list va; if (level > _debugLevel) return; va_start(va, s); vsprintf(buf, s, va); va_end(va); printf("%s\n", buf); #if defined( USE_WINDBG ) strcat(buf, "\n"); #if defined( _WIN32_WCE ) TCHAR buf_unicode[1024]; MultiByteToWideChar(CP_ACP, 0, buf, strlen(buf) + 1, buf_unicode, sizeof(buf_unicode)); OutputDebugString(buf_unicode); #else OutputDebugString(buf); #endif #endif fflush(stdout); } void checkHeap() { #if defined(_MSC_VER) if (_heapchk() != _HEAPOK) { error("Heap is invalid!"); } #endif }
