I18N::Collate(3p)Perl Programmers Reference GuidI18N::Collate(3p)


NAME
       I18N::Collate - compare 8-bit scalar data according to the
       current locale

SYNOPSIS
           use I18N::Collate;
           setlocale(LC_COLLATE, 'locale-of-your-choice');
           $s1 = new I18N::Collate "scalar_data_1";
           $s2 = new I18N::Collate "scalar_data_2";

DESCRIPTION
         ***

         WARNING: starting from the Perl version 5.003_06
         the I18N::Collate interface for comparing 8-bit scalar data
         according to the current locale

               HAS BEEN DEPRECATED

         That is, please do not use it anymore for any new applications
         and please migrate the old applications away from it because its
         functionality was integrated into the Perl core language in the
         release 5.003_06.

         See the perllocale manual page for further information.

         ***

       This module provides you with objects that will collate
       according to your national character set, provided that
       the POSIX setlocale() function is supported on your sys-
       tem.

       You can compare $s1 and $s2 above with

           $s1 le $s2

       to extract the data itself, you'll need a dereference:
       $$s1

       This module uses POSIX::setlocale(). The basic collation
       conversion is done by strxfrm() which terminates at NUL
       characters being a decent C routine.  collate_xfrm() han-
       dles embedded NUL characters gracefully.

       The available locales depend on your operating system; try
       whether "locale -a" shows them or man pages for "locale"
       or "nlsinfo" or the direct approach "ls /usr/lib/nls/loc"
       or "ls /usr/lib/nls" or "ls /usr/lib/locale".  Not all the
       locales that your vendor supports are necessarily
       installed: please consult your operating system's documen-
       tation and possibly your local system administration.  The
       locale names are probably something like
       "xx_XX.(ISO)?8859-N" or "xx_XX.(ISO)?8859N", for example
