Thu Mar 28 03:25:10 1996 Roland McGrath <roland@charlie-brown.gnu.ai.mit.edu>
* intl/Makefile (copysrc): Add missing > in sed cmd. Sat Mar 23 17:52:49 1996 Ulrich Drepper <drepper@gnu.ai.mit.edu> * Makeconfig: Rename Makefile variable nlsdir to i18ndir and change value to $(datadir)/i18n. `nls' is not an appropriate name. * Makefile (subdirs): Add new subdir wctype. * ctype/ctype-info.c: Add new global variable __ctype_names and initialize from _nl_C_LC_CTYPE. * ctype/ctype.h: In P1003.3b/D11 `alnum' is a separate character class. Use bit 11. [_ISbit]: Protect definition of bitmasks because they are also used in wctype.h. * libio/genops.c (_IO_sputbackc, _IO_sungetc): Clear EOF flag after successfully pushing back a character. Fundamental changes in locale implementation. Almost nothing from the old code is used anymore. * locale/charmap.c, locale/collate.c, locale/config.h, locale/ctypedump.c, locale/hash.h, locale/keyword.gperf, locale/keyword.h, locale/loadlocale.c, locale/locale-ctype.c, locale/locale.c locale/localeconv.c, locale/localedef.c, locale/localedef.h, locale/locfile-hash.c, locale/locfile-lex.c, locale/locfile-parse.c, locale/messages.c, locale/monetary.c, locale/numeric.c, locale/setlocale.c, locale/token.h, locale/xmalloc.c: Removed. * locale/Makefile: Update for new locale implementation with program source code distributed in subdir. * locale/categories.def, locale/iso-4217.def: Updated file for new locale implementation. * locale/langinfo.h: Updated for new locale implementation. (ERA_D_T_FMT, ERA_T_FMT): New official values according to P1003.2b/D11. (_NL_COLLATE_NRULES, _NL_COLLATE_RULES, _NL_COLLATE_HASH_SIZE, _NL_COLLATE_HASH_LAYERS, _NL_COLLATE_TABLE_EB, _NL_COLLATE_TABLE_EL, _NL_COLLATE_UNDEFINED, _NL_COLLATE_EXTRA_EB, _NL_COLLATE_EXTRA_EL, _NL_CTYPE_NAMES_EB, _NL_CTYPE_NAMES_EL, _NL_CTYPE_HASH_SIZE, _NL_CTYPE_HASH_LAYERS, _NL_CTYPE_CLASS_NAMES, _NL_CTYPE_MAP_NAMES, _NL_CTYPE_WIDTH): New internal values for extended LC_CTYPE and LC_COLLATE implementation. * locale/simple-hash.c, locale/simple-hash.h, locale/xmalloc.c, locale/xstrdup.c: Helper functions for locale related programs. * locale/C-collate.c, locale/C-ctype.c, locale/C-messages.c, locale/C-monetary.c, locale/C-numeric.c, locale/C-time.c, locale/lc-collate.c, locale/lc-ctype.c, locale/lc-messages.c, locale/lc-monetary.c, locale/lc-numeric.c, locale/lc-time.c: New implementation of locale functions, and new generated "C" locale data. * locale/loadlocale.c: Now handles word fields in locale binary automatically by changing the endianess if necessary. * locale/localeinfo.h (LIMAGIC): Changed magic number because of incompatible changes. (locale_data): Changed definition to allow word as a value type. (coll_sort_rule): Values for collation sorting mode. (_NL_CURRENT_WORD): New macro to access word value of locale entry. (__collate_table, __collate_extra): Declare new global variables for collation tables. * locale/programs/charmap-kw.gperf, locale/programs/charmap-kw.h, locale/programs/charmap.c, locale/programs/charset.c, locale/programs/charset.h, locale/programs/config.h, locale/programs/ctypedump.c, locale/programs/ld-collate.c, locale/programs/ld-ctype.c, locale/programs/ld-messages.c, locale/programs/ld-monetary.c, locale/programs/ld-numeric.c, locale/programs/ld-time.c, locale/programs/linereader.c, locale/programs/linereader.h, locale/programs/locale.c, locale/programs/localedef.c, locale/programs/locales.h, locale/programs/locfile-kw.gperf, locale/programs/locfile-kw.h, locale/programs/locfile-token.h, locale/programs/locfile.c, locale/programs/locfile.h, locale/programs/stringtrans.c, locale/programs/stringtrans.h: Implementation of locale related programs. * locale/weight.h: Functions to access collation tables. * posix/unistd.h: Define _POSIX2_LOCALEDEF. * stdio-common/printf_fp.c: Fix bug with printing certain numbers < 10^-1. Reported by Bill Metzenthen. * stdio-common/tfformat.c: Add new test for above bug. * string/strcoll.c, string/strxfrm.c: Real implementation of string collation according to ISO C. * wctype/Makefile, wctype/cname-lookup.h, wctype/iswctype.c, wctype/test_wctype.c, wctype/towctrans.c, wctype/wcfuncs.c, wctype/wctrans.c, wctype/wctype.c, wctype/wctype.h: New files. Implementation of wide character classes and mapping.
