Install

1. Download the tarball and extract it.
2. perl Makefile.PL
3. make
4. make install

Alternatively, just putting all files in the directory lib into your directory for Perl modules should work as well. All Perl modules in this package are written in pure Perl.

Example

use Char::Class::XML qw/InXML_NameStartChar10 InXMLNameChar10/;

if ($name !~ /\A\p{InXML_NameStartChar10}\p{InXMLNameChar10}*\z/) {
  die "$0: $name: This is not an XML 1.0 Name";
}

Distribution

$ git clone http://suika.fam.cx/gate/git/bare/charclass.git/

There was a snapshot release version, which is outdated and should not be used:

TODO

• Some classes are no longer up-to-date. Need to update.
• Need to improve documentation.

Note that there is a bug tracking system.
