It is still ugly. I opted out of floating point - * numbers, but the formatter understands just about everything - * from the normal C string format, at least as far as I can tell from - * the Solaris 2.5 printf(3S) man page. - * - * Brandon Long 10/22/97 for mutt 0.87.1 - * Ok, added some minimal floating point support, which means this - * probably requires libm on most operating systems. Don't yet - * support the exponent (e,E) and sigfig (g,G). Also, fmtint() - * was pretty badly broken, it just wasn't being exercised in ways - * which showed it, so that's been fixed. Also, formated the code - * to mutt conventions, and removed dead code left over from the - * original. Also, there is now a builtin-test, just compile with: - * gcc -DTEST_SNPRINTF -o snprintf snprintf.c -lm - * and run snprintf for results. - * - * Thomas Roessler 01/27/98 for mutt 0.89i - * The PGP code was using unsigned hexadecimal formats. - * Unfortunately, unsigned formats simply didn't work. - * - * Michael Elkins 03/05/98 for mutt 0.90.8 - * The original code assumed that both snprintf() and vsnprintf() were - * missing. Some systems only have snprintf() but not vsnprintf(), so - * the code is now broken down under HAVE_SNPRINTF and HAVE_VSNPRINTF. - * - * Andrew Tridgell (tridge@samba.org) Oct 1998 - * fixed handling of %.0f - * added test for HAVE_LONG_DOUBLE - * - * tridge@samba.org, idra@samba.org, April 2001 - * got rid of fcvt code (twas buggy and made testing harder) - * added C99 semantics - * - **************************************************************/ - -#ifndef NO_CONFIG_H /* for some tests */ -#include "config.h" -#else -#define NULL 0 -#endif - -#ifdef TEST_SNPRINTF /* need math library headers for testing */ -#include -#endif - -#ifdef HAVE_STRING_H -#include -#endif - -#ifdef HAVE_STRINGS_H -#include -#endif -#ifdef HAVE_CTYPE_H -#include -#endif -#include -#include -#ifdef HAVE_STDLIB_H -#include -#endif - -#ifndef VA_COPY -#ifdef HAVE_VA_COPY -#define VA_COPY(dest, src) va_copy(dest, src) -#elif defined(HAVE___VA_COPY) -#define VA_COPY(dest, src) __va_copy(dest, src) -#else -#define VA_COPY(dest, src) (dest) = (src) -#endif -#endif - - -#if defined(HAVE_SNPRINTF) && defined(HAVE_VSNPRINTF) && defined(HAVE_C99_VSNPRINTF) -/* only include stdio.h if we are not re-defining snprintf or vsnprintf */ -#include - /* make the compiler happy with an empty file */ - void dummy_snprintf(void) {} -#else - -#ifdef HAVE_LONG_DOUBLE -#define LDOUBLE long double -#else -#define LDOUBLE double -#endif - -#ifdef HAVE_LONG_LONG -#define LLONG long long -#else -#define LLONG long -#endif - -/* free memory if the pointer is valid and zero the pointer */ -#ifndef SAFE_FREE -#define SAFE_FREE(x) do { if ((x) != NULL) {free((x)); (x)=NULL;} } while(0) -#endif - -static size_t dopr(char *buffer, size_t maxlen, const char *format, - va_list args_in); -static void fmtstr(char *buffer, size_t *currlen, size_t maxlen, - char *value, int flags, int min, int max); -static void fmtint(char *buffer, size_t *currlen, size_t maxlen, - long value, int base, int min, int max, int flags); -static void fmtfp(char *buffer, size_t *currlen, size_t maxlen, - LDOUBLE fvalue, int min, int max, int flags); -static void dopr_outch(char *buffer, size_t *currlen, size_t maxlen, char c); - -/* - * dopr(): poor man's version of doprintf - */ - -/* format read states */ -#define DP_S_DEFAULT 0 -#define DP_S_FLAGS 1 -#define DP_S_MIN 2 -#define DP_S_DOT 3 -#define DP_S_MAX 4 -#define DP_S_MOD 5 -#define DP_S_CONV 6 -#define DP_S_DONE 7 - -/* format flags - Bits */ -#define DP_F_MINUS (1 << 0) -#define DP_F_PLUS (1 << 1) -#define DP_F_SPACE (1 << 2) -#define DP_F_NUM (1 << 3) -#define DP_F_ZERO (1 << 4) -#define DP_F_UP (1 << 5) -#define DP_F_UNSIGNED (1 << 6) - -/* Conversion Flags */ -#define DP_C_SHORT 1 -#define DP_C_LONG 2 -#define DP_C_LDOUBLE 3 -#define DP_C_LLONG 4 - -#define char_to_int(p) ((p)- '0') -#ifndef MAX -#define MAX(p,q) (((p) >= (q)) ?
