- =head1 NAME
-
- Collate - compare 8-bit scalar data according to the current locale
-
- =head1 SYNOPSIS
-
- use Collate;
- setlocale(LC_COLLATE, 'locale-of-your-choice');
- $s1 = new Collate "scalar_data_1";
- $s2 = new Collate "scalar_data_2";
-
- =head1 DESCRIPTION
-
- This module provides you with objects that will collate
- according to your national character set, providing the
- POSIX setlocale() function should be 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 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. Due to C<cmp>
- and overload magic, C<lt>, C<le>, C<eq>, C<ge>, and C<gt> work also. The
- available locales depend on your operating system; try whether C<locale
- -a> shows them or the more direct approach C<ls /usr/lib/nls/loc> or C<ls
- /usr/lib/nls>. The locale names are probably something like
- "xx_XX.(ISO)?8859-N".
