As and when we * migrate to a newer compiler, we'll have to adjust this to * match; however, for the moment we faithfully imitate in our GUI * utilities what our CLI utilities can't be prevented from doing. * * When I investigated this, at first glance the rules appeared to * be: * * - Single quotes are not special characters. * * - Double quotes are removed, but within them spaces cease * to be special. * * - Backslashes are _only_ special when a sequence of them * appear just before a double quote. In this situation, * they are treated like C backslashes: so \" just gives a * literal quote, \\" gives a literal backslash and then * opens or closes a double-quoted segment, \\\" gives a * literal backslash and then a literal quote, \\\\" gives * two literal backslashes and then opens/closes a * double-quoted segment, and so forth. Note that this * behaviour is identical inside and outside double quotes. * * - Two successive double quotes become one literal double * quote, but only _inside_ a double-quoted segment. * Outside, they just form an empty double-quoted segment * (which may cause an empty argument word). * * - That only leaves the interesting question of what happens * when one or more backslashes precedes two or more double * quotes, starting inside a double-quoted string. And the * answer to that appears somewhat bizarre. Here I tabulate * number of backslashes (across the top) against number of * quotes (down the left), and indicate how many backslashes * are output, how many quotes are output, and whether a * quoted segment is open at the end of the sequence: * * backslashes * * 0 1 2 3 4 * * 0 0,0,y | 1,0,y 2,0,y 3,0,y 4,0,y * --------+----------------------------- * 1 0,0,n | 0,1,y 1,0,n 1,1,y 2,0,n * q 2 0,1,n | 0,1,n 1,1,n 1,1,n 2,1,n * u 3 0,1,y | 0,2,n 1,1,y 1,2,n 2,1,y * o 4 0,1,n | 0,2,y 1,1,n 1,2,y 2,1,n * t 5 0,2,n | 0,2,n 1,2,n 1,2,n 2,2,n * e 6 0,2,y | 0,3,n 1,2,y 1,3,n 2,2,y * s 7 0,2,n | 0,3,y 1,2,n 1,3,y 2,2,n * 8 0,3,n | 0,3,n 1,3,n 1,3,n 2,3,n * 9 0,3,y | 0,4,n 1,3,y 1,4,n 2,3,y * 10 0,3,n | 0,4,y 1,3,n 1,4,y 2,3,n * 11 0,4,n | 0,4,n 1,4,n 1,4,n 2,4,n * * * [Test fragment was of the form "a\\\"""b c" d.] * * There is very weird mod-3 behaviour going on here in the * number of quotes, and it even applies when there aren't any * backslashes! How ghastly. * * With a bit of thought, this extremely odd diagram suddenly * coalesced itself into a coherent, if still ghastly, model of * how things work: * * - As before, backslashes are only special when one or more * of them appear contiguously before at least one double * quote. In this situation the backslashes do exactly what * you'd expect: each one quotes the next thing in front of * it, so you end up with n/2 literal backslashes (if n is * even) or (n-1)/2 literal backslashes and a literal quote * (if n is odd). In the latter case the double quote * character right after the backslashes is used up. * * - After that, any remaining double quotes are processed. A * string of contiguous unescaped double quotes has a mod-3 * behaviour: * * * inside a quoted segment, a quote ends the segment. * * _immediately_ after ending a quoted segment, a quote * simply produces a literal quote. * * otherwise, outside a quoted segment, a quote begins a * quoted segment. * * So, for example, if we started inside a quoted segment * then two contiguous quotes would close the segment and * produce a literal quote; three would close the segment, * produce a literal quote, and open a new segment. If we * started outside a quoted segment, then two contiguous * quotes would open and then close a segment, producing no * output (but potentially creating a zero-length argument); * but three quotes would open and close a segment and then * produce a literal quote. */ /* * First deal with the simplest of all special cases: if there * aren't any arguments, return 0,NULL,NULL. */ while (*cmdline && isspace(*cmdline)) cmdline++; if (!*cmdline) { if (argc) *argc = 0; if (argv) *argv = NULL; if (argstart) *argstart = NULL; return; } /* * This will guaranteeably be big enough; we can realloc it * down later. */ outputline = snewn(1+strlen(cmdline), char); outputargv = snewn(strlen(cmdline)+1 / 2, char *); outputargstart = snewn(strlen(cmdline)+1 / 2, char *); p = cmdline; q = outputline; outputargc = 0; while (*p) { bool quote; /* Skip whitespace searching for start of argument. */ while (*p && isspace(*p)) p++; if (!*p) break; /* We have an argument; start it. */ outputargv[outputargc] = q; outputargstart[outputargc] = p; outputargc++; quote = false; /* Copy data into the argument until it's finished. */ while (*p) { if (!quote && isspace(*p)) break; /* argument is finished */ if (*p == '"' || *p == '\\') { /* * We have a sequence of zero or more backslashes * followed by a sequence of zero or more quotes. * Count up how many of each, and then deal with * them as appropriate. */ int i, slashes = 0, quotes = 0; while (*p == '\\') slashes++, p++; while (*p == '"') quotes++, p++; if (!quotes) { /* * Special case: if there are no quotes, * slashes are not special at all, so just copy * n slashes to the output string. */ while (slashes--) *q++ = '\\'; } else { /* Slashes annihilate in pairs. */ while (slashes >= 2) slashes -= 2, *q++ = '\\'; /* One remaining slash takes out the first quote. */ if (slashes) quotes--, *q++ = '"'; if (quotes > 0) { /* Outside a quote segment, a quote starts one. */ if (!quote) quotes--, quote = true; /* Now we produce (n+1)/3 literal quotes... */ for (i = 3; i <= quotes+1; i += 3) *q++ = '"'; /* ... and end in a quote segment iff 3 divides n. */ quote = (quotes % 3 == 0); } } } else { *q++ = *p++; } } /* At the end of an argument, just append a trailing NUL. */ *q++ = '\0'; } outputargv = sresize(outputargv, outputargc, char *); outputargstart = sresize(outputargstart, outputargc, char *); if (argc) *argc = outputargc; if (argv) *argv = outputargv; else sfree(outputargv); if (argstart) *argstart = outputargstart; else sfree(outputargstart); } int WINAPI WinMain(HINSTANCE inst, HINSTANCE prev, LPSTR cmdline, int show) { MSG msg; char *error = NULL; const game *gg; frontend *fe; midend *me; int argc; char **argv; split_into_argv(cmdline, &argc, &argv, NULL); InitCommonControls(); if (!prev) { WNDCLASS wndclass; wndclass.style = 0; wndclass.lpfnWndProc = WndProc; wndclass.cbClsExtra = 0; wndclass.cbWndExtra = 0; wndclass.hInstance = inst; wndclass.hIcon = LoadIcon(inst, MAKEINTRESOURCE(200)); if (!wndclass.hIcon) /* in case resource file is absent */ wndclass.hIcon = LoadIcon(inst, IDI_APPLICATION); wndclass.hCursor = LoadCursor(NULL, IDC_ARROW); wndclass.hbrBackground = NULL; wndclass.lpszMenuName = NULL; wndclass.lpszClassName = CLASSNAME; RegisterClass(&wndclass); } while (*cmdline && isspace((unsigned char)*cmdline)) cmdline++; init_help(); #ifdef COMBINED gg = gamelist[0]; if (argc > 0) { int i; for (i = 0; i < gamecount; i++) { const char *p = gamelist[i]->name; char *q = argv[0]; while (*p && *q) { if (isspace((unsigned char)*p)) { while (*q && isspace((unsigned char)*q)) q++; } else { if (tolower((unsigned char)*p) != tolower((unsigned char)*q)) break; q++; } p++; } if (!*p) { gg = gamelist[i]; --argc; ++argv; break; } } } #else gg = &thegame; #endif fe = frontend_new(inst); me = midend_for_new_game(fe, gg, argc > 0 ? argv[0] : NULL, true, true, &error); if (!me) { char buf[128]; #ifdef COMBINED sprintf(buf, "Puzzles Error"); #else sprintf(buf, "%.100s Error", gg->name); #endif MessageBox(NULL, error, buf, MB_OK|MB_ICONERROR); sfree(error); return 1; } fe_set_midend(fe, me); show_window(fe); while (GetMessage(&msg, NULL, 0, 0)) { DispatchMessage(&msg); } DestroyWindow(fe->hwnd); cleanup_help(); return msg.wParam; } /* vim: set shiftwidth=4 tabstop=8: */
