with ALL_80_TO_FF_SW1 defined. This is not correct in the general case,
but helps in certain restricted environments where nothing but the
default locale is available and we know what we do(tm).
- add wcstok() and wcswcs(),
- add wcstok(3),
- move btowc() and wctob() into each ctype modules,
- bump ctype interface ABI version,
- bump i18n modules' minor and
- update sets.
and fix a stupid bug in _RUNE_ISCACHED macro.
- add libc/citrus directory.
this directory contains the common stuffs not only for locale
but also other facilities relating to i18n (e.g. iconv).
- To keep the binary compatibility for the ctype modules easily,
the interface between libc and the modules is simplified.
- For the future integrated extension, module pool is renamed
from "/usr/lib/runemodule" to "/usr/lib/i18n".
In the future, this directory will contain the modules for "iconv",
"collation", etc.
- some cosmetic changes.
- Bug fix for runetype.h; __attribute__((__packed__)) is placed at
the wrong position and it is invalid unintentionally.
But, the all members of the structures seem well-aligned. Thus,
this bug causes no problem, hopefully.
HEADS UP:
- /usr/lib/rumemodule is obsoleted. If you use the multibyte locales,
you need to install /usr/lib/i18n/* from sys/lib/i18n_module .
- The binary compatibility of /usr/share/locale/*/LC_CTYPE is probably kept.
Perhaps, the bug fix about __packed__ mentioned above breaks the
compatibility... Be careful especially on 64bit platforms.
#define _DEFAULT_INVALID_RUNE -3
and use it accordingly. Also provides a representation programs such as
mklocale can reference when filling out a new locale from a definition.
shot-term TODO:
- enable multibyte locales. this includes loadable locale modules
(#ifdef DLRUNE).
- populate LC_CTYPE definition files.
- other functions such as iconv()
- make libc functions more friendly with multibyte.
- multilingualize other LC_xx
- torture tests
XXX don't forget to "make depend" when you rebuild libc, multibyte.c is
moved from lib/libc/stdlib to lib/libc/locale.
