The glibc extension + * __wcsnrtombs() hasn't been tested, as I didn't find a test for it + * in the glibc source. I also need to fix the behavior of + * _wchar_utf8sntowcs() if the max number of wchars to convert is 0. + * + * UTF-8 -> wchar -> UTF-8 conversion tests on Markus Kuhn's UTF-8-demo.txt + * file on my platform (x86) show about 5-10% faster conversion speed than + * glibc with mbsrtowcs()/wcsrtombs() and almost twice as fast as glibc with + * individual mbrtowc()/wcrtomb() calls. + * + * If 'DECODER' is defined, then _wchar_utf8sntowcs() will be compiled + * as a fail-safe UTF-8 decoder appropriate for a terminal, etc. which + * needs to deal gracefully with whatever is sent to it. In that mode, + * it passes Markus Kuhn's UTF-8-test.txt stress test. I plan to add + * an arg to force that behavior, so the interface will be changing. + * + * I need to fix the error checking for 16-bit wide chars. This isn't + * an issue for uClibc, but may be for ELKS. I'm currently not sure + * if I'll use 16-bit, 32-bit, or configureable wchars in ELKS. + * + * July 1, 2002 + * + * Fixed _wchar_utf8sntowcs() for the max number of wchars == 0 case. + * Fixed nul-char bug in btowc(), and another in __mbsnrtowcs() for 8-bit + * locales. + * Enabled building of a C/POSIX-locale-only version, so full locale support + * no longer needs to be enabled. + * + * Nov 4, 2002 + * + * Fixed a bug in _wchar_wcsntoutf8s(). Don't store wcs position if dst is NULL. + * Also, introduce an awful hack into _wchar_wcsntoutf8s() and wcsrtombs() in + * order to support %ls in printf. See comments below for details. + * Change behaviour of wc<->mb functions when in the C locale. Now they do + * a 1-1 map for the range 0x80-UCHAR_MAX. This is for backwards compatibility + * and consistency with the stds requirements that a printf format string by + * a valid multibyte string beginning and ending in it's initial shift state. + * + * Nov 5, 2002 + * + * Forgot to change btowc and wctob when I changed the wc<->mb functions yesterday. + * + * Nov 7, 2002 + * + * Add wcwidth and wcswidth, based on Markus Kuhn's wcwidth of 2002-05-08. + * Added some size/speed optimizations and integrated it into my locale + * framework. Minimally tested at the moment, but the stub C-locale + * version (which most people would probably be using) should be fine. + * + * Nov 21, 2002 + * + * Revert the wc<->mb changes from earlier this month involving the C-locale. + * Add a couple of ugly hacks to support *wprintf. + * Add a mini iconv() and iconv implementation (requires locale support). + * + * Aug 1, 2003 + * Bug fix for mbrtowc. + * + * Aug 18, 2003 + * Bug fix: _wchar_utf8sntowcs and _wchar_wcsntoutf8s now set errno if EILSEQ. + * + * Feb 11, 2004 + * Bug fix: Fix size check for remaining output space in iconv(). + * + * Manuel + */ + +#include "porting.h" +#include +#include +#include +#include +#include +#include "wchar.c" /* for _UC_iconv_t and __iconv_codesets */ + +extern const unsigned char __iconv_codesets[]; + +#define IBUF BUFSIZ +#define OBUF BUFSIZ + +static char *progname; +static int hide_errors; + +static void error_msg(const char *fmt, ...) + __attribute__ ((noreturn, format (printf, 1, 2))); + +static void error_msg(const char *fmt, ...) +{ + va_list arg; + + if (!hide_errors) { + fprintf(stderr, "%s: ", progname); + va_start(arg, fmt); + vfprintf(stderr, fmt, arg); + va_end(arg); + } + + exit(EXIT_FAILURE); +} + +int main(int argc, char **argv) +{ + FILE *ifile; + FILE *ofile = stdout; + const char *p; + const char *s; + static const char opt_chars[] = "tfocsl"; + /* 012345 */ + const char *opts[sizeof(opt_chars)]; /* last is infile name */ + iconv_t ic; + char ibuf[IBUF]; + char obuf[OBUF]; + char *pi; + char *po; + size_t ni, no, r, pos; + + hide_errors = 0; + + for (s = opt_chars ; *s ; s++) { + opts[ s - opt_chars ] = NULL; + } + + progname = *argv; + while (--argc) { + p = *++argv; + if ((*p != '-') || (*++p == 0)) { + break; + } + do { + if ((s = strchr(opt_chars,*p)) == NULL) { + USAGE: + s = basename(progname); + fprintf(stderr, + "%s [-cs] -f fromcode -t tocode [-o outputfile] [inputfile ...]\n" + " or\n%s -l\n", s, s); + return EXIT_FAILURE; + } + if ((s - opt_chars) < 3) { + if ((--argc == 0) || opts[s - opt_chars]) { + goto USAGE; + } + opts[s - opt_chars] = *++argv; + } else { + opts[s - opt_chars] = p; + } + } while (*++p); + } + + if (opts[5]) { /* -l */ + fprintf(stderr, "Recognized codesets:\n"); + for (s = (char *)__iconv_codesets ; *s ; s += *s) { + fprintf(stderr," %s\n", s+2); + } + s = __LOCALE_DATA_CODESET_LIST; + do { + fprintf(stderr," %s\n", __LOCALE_DATA_CODESET_LIST+ (unsigned char)(*s)); + } while (*++s); + + return EXIT_SUCCESS; + } + + if (opts[4]) { + hide_errors = 1; + } + + if (!opts[0] || !opts[1]) { + goto USAGE; + } + if ((ic = iconv_open(opts[0],opts[1])) == ((iconv_t)(-1))) { + error_msg( "unsupported codeset in %s -> %s conversion\n", opts[1], opts[0]); + } + if (opts[3]) { /* -c */ + ((_UC_iconv_t *) ic)->skip_invalid_input = 1; + } + + if ((s = opts[2]) != NULL) { + if (!(ofile = fopen(s, "w"))) { + error_msg( "couldn't open %s for writing\n", s); + } + } + + pos = ni = 0; + do { + if (!argc || ((**argv == '-') && !((*argv)[1]))) { + ifile = stdin; /* we don't check for duplicates */ + } else if (!(ifile = fopen(*argv, "r"))) { + error_msg( "couldn't open %s for reading\n", *argv); + } + + while ((r = fread(ibuf + ni, 1, IBUF - ni, ifile)) > 0) { + pos += r; + ni += r; + no = OBUF; + pi = ibuf; + po = obuf; + if ((r = iconv(ic, &pi, &ni, &po, &no)) == ((size_t)(-1))) { + if ((errno != EINVAL) && (errno != E2BIG)) { + error_msg( "iconv failed at pos %lu : %m\n", (unsigned long) (pos - ni)); + } + } + if ((r = OBUF - no) > 0) { + if (fwrite(obuf, 1, OBUF - no, ofile) < r) { + error_msg( "write error\n"); + } + } + if (ni) { /* still bytes in buffer! */ + memmove(ibuf, pi, ni); + } + } + + if (ferror(ifile)) { + error_msg( "read error\n"); + } + + ++argv; + + if (ifile != stdin) { + fclose(ifile); + } + + } while (--argc > 0); + + iconv_close(ic); + + if (ni) { + error_msg( "incomplete sequence\n"); + } + + return (((_UC_iconv_t *) ic)->skip_invalid_input < 2) + ?
