(__ctype32_wctype, __ctype32_wctrans): Declare external. (__iswalnum, __iswalpha, __iswcntrl, __iswdigit, __iswlower, __iswgraph, __iswprint, __iswpunct, __iswspace, __iswupper, __iswxdigit, towlower, towupper): Support alternate locale format with 3-level tables. * wctype/wcextra.c (iswblank): Likewise. * wctype/wcfuncs_l.c: Include "wchar-lookup.h". (__iswalnum_l, __iswalpha_l, __iswcntrl_l, __iswdigit_l, __iswlower_l, __iswgraph_l, __iswprint_l, __iswpunct_l, __iswspace_l, __iswupper_l, __iswxdigit_l, __towlower_l, __towupper_l): Support alternate locale format with 3-level tables. * wctype/wcextra_l.c (__iswblank_l): Likewise. * wctype/wctype.c (__wctype): Likewise. In the alternate locale format, return a 3-level table pointer. * wctype/wctype_l.c (__wctype_l): Likewise. * wctype/wctrans.c (wctrans): Likewise. * wctype/wctype.h (__ISwupper, __ISwlower, __ISwalpha, __ISwdigit, __ISwxdigit, __ISwspace, __ISwprint, __ISwgraph, __ISwblank, __ISwcntrl, __ISwpunct, __ISwalnum): New enum values. (iswctype): Remove macro definition. * wcsmbs/wcwidth.h: Include "wchar-lookup.h". (internal_wcwidth): Support alternate locale format with 3-level tables. * locale/langinfo.h (_NL_CTYPE_CLASS_OFFSET, _NL_CTYPE_MAP_OFFSET): New nl_items. * locale/categories.def (_NL_CTYPE_CLASS_OFFSET, _NL_CTYPE_MAP_OFFSET): Define them as being type "word". * locale/C-ctype.c (_nl_C_LC_CTYPE): Add initializers for them. * ctype/ctype-info.c (__ctype32_wctype, __ctype32_wctrans, __ctype32_width): New exported variables. * locale/lc-ctype.c (_nl_postload_ctype): Initialize them in the alternate locale format. Don't initialize __ctype_names and __ctype_width in the alternate locale format. * locale/programs/localedef.h (oldstyle_tables): New declaration. * locale/programs/localedef.c (oldstyle_tables): New variable. (OPT_OLDSTYLE): New macro. (options): Add --old-style option. (parse_opt): Handle --old-style option. * locale/programs/ld-ctype.c (locale_ctype_t): Add class_offset, map_offset, class_3level, map_3level, width_3level members. (ctype_output): Support for alternate locale format: Computation of nelems changes. _NL_CTYPE_TOUPPER32, _NL_CTYPE_TOLOWER32 and _NL_CTYPE_CLASS32 only 256 characters. _NL_CTYPE_NAMES empty. New fields _NL_CTYPE_CLASS_OFFSET, _NL_CTYPE_MAP_OFFSET. Field _NL_CTYPE_WIDTH now contains the three-level table. Extra elems now contain both class and map tables. (struct wctype_table): New type. (wctype_table_init, wctype_table_add, wctype_table_finalize): New functions. (struct wcwidth_table): New type. (wcwidth_table_init, wcwidth_table_add, wcwidth_table_finalize): New functions. (struct wctrans_table): New type. (wctrans_table_init, wctrans_table_add, wctrans_table_finalize): New functions. (allocate_arrays): Support for alternate locale format: Set plane_size and plane_cnt to 0. Restrict ctype->ctype32_b to the first 256 characters. Compute ctype->class_3level. Restrict ctype->map32[idx] to the first 256 characters. Compute ctype->map_3level. Set ctype->class_offset and ctype->map_offset. Compute ctype->width_3level instead of ctype->width. --- wctype/wcextra_l.c | 36 ++++++++++++++++++++++++------------ 1 file changed, 24 insertions(+), 12 deletions(-) (limited to 'wctype/wcextra_l.c') diff --git a/wctype/wcextra_l.c b/wctype/wcextra_l.c index d326327954..8fc9c2733d 100644 --- a/wctype/wcextra_l.c +++ b/wctype/wcextra_l.c @@ -1,5 +1,5 @@ /* Additional non standardized wide character classification functions. - Copyright (C) 1997, 1999 Free Software Foundation, Inc. + Copyright (C) 1997, 1999, 2000 Free Software Foundation, Inc.
