1 Unicode/Collate version 0.67
2 ===============================
6 Unicode::Collate - Unicode Collation Algorithm
13 $Collator = Unicode::Collate->new(%tailoring);
16 @sorted = $Collator->sort(@not_sorted);
19 $result = $Collator->cmp($a, $b); # returns 1, 0, or -1.
20 $result = $Collator->eq($a, $b); # returns true/false
21 (similarly ->ne, ->lt, ->le, ->gt, ->ge)
23 Note: Strings in @not_sorted, $a and $b are interpreted
24 according to Perl's Unicode support. See perlunicode,
25 perluniintro, perlunitut, perlunifaq, utf8.
26 Otherwise you can use "preprocess" or should decode them before.
30 Perl 5.6.1 or later is required.
31 Perl 5.8.1 or later is recommended.
33 Though this distribution contains a subset of an old DUCET, named
34 "keys.txt", this one is intended only for doing a test of this module
35 and practically useless for any other purpose.
37 Installation of Unicode::Collate::Locale requires Collate/Locale.pm,
38 Collate/Locale/*.pm, Collate/CJK/*.pm and Collate/allkeys.txt.
39 On building, Unicode::Collate::Locale doesn't require any of data/*.txt,
40 gendata/*, and mklocale.
41 Tests for Unicode::Collate::Locale are named t/loc_*.t.
43 To install this module type the following:
50 If you have a C compiler and want to use XSUB edition,
51 type the following (!! "enableXS" must run before "Makefile.PL" !!):
59 If you decide to install pure Perl (i.e. non-XS) edition after trying
60 to build XSUB, type the following:
71 The conformant collation requires Unicode::Normalize (v 0.10 or later)
72 although Unicode::Collate can be used without Unicode::Normalize.
76 Though this module can be used without any C<table> file,
77 to use this module easily, it is recommended to install a table file
78 in the UCA format, by copying it under the directory
79 <a place in @INC>/Unicode/Collate.
81 You can install such a table file by adding it to "Collate" directory
82 (where "keys.txt" is placed) in this distribution before executing
85 The most preferable one is "The Default Unicode Collation Element Table"
86 (aka DUCET), available from the Unicode Consortium's website:
88 http://www.unicode.org/Public/UCA/
90 http://www.unicode.org/Public/UCA/latest/allkeys.txt (latest version)
92 If DUCET is not installed, it is recommended to copy the file
93 from http://www.unicode.org/Public/UCA/latest/allkeys.txt
94 to <a place in @INC>/Unicode/Collate/allkeys.txt manually.
96 HOW TO CHANGE DUCET (NOT WARRANTED)
98 0. rewriting UCA_Version and Base_Unicode_Version in Collate.pm
99 and t/version.t is preferred.
100 1. replace Collate/allkeys.txt with a new DUCET.
101 2. run mklocale to generate new Locale/*.pl and Korean.pm.
102 3. replace Collate/Locale/*.pl with the new Locale/*.pl,
103 and Collate/CJK/Korean.pm with the new Korean.pm.
105 IF FAIL, it may require more changes, not be easy.
