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

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


NAME

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


  ***

  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.

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

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 system.

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() handles 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 documentation 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 fr_CH.ISO8859-1 is the Swiss (CH) variant of French (fr), ISO Latin (8859) 1 (-1) which is the Western European character set.
