NAME

Sub::CharacterProperties - Support for user-defined character properties

VERSION

version 1.100860

SYNOPSIS

    my $n = Sub::CharacterProperties->new(characters => [
        'LATIN SMALL LETTER A',
        'LATIN SMALL LETTER B',
        'LATIN SMALL LETTER C',
        'LATIN SMALL LETTER D',
        # ...
    ]);
    print $n->as_code('MySet');

DESCRIPTION

As described in perlunicode, you can define your own character properties. To do so, you need to specify the ranges of allowed characters as pairs of hexadecimal numbers. There are easier ways of combining ranges with +, -, ! and &, but if you have a diverse set of characters you are going to have to deal with hex values.

This module aims at making your task of writing these character property subroutines easier.

Basically you create an object of this class, pass it a list of the Unicode character names of the characters you'd like to allow and then have it generate the character property subroutine.

Each character should be either a Unicode character name - such as LATIN SMALL LETTER A - or a hex code point - indicated by a leading 0x - this is useful for characters that don't have a name.

The character property subroutines are a compile-time feature, so unfortunately this module can't just install the generated subroutine. You will have to copy-and-paste it into your program.

METHODS

get_ranges

Assumes that the characters() have been set.

Returns a list of ranges containing character numeric values; each range is a Set::IntRange object.

as_code

Assumes that the characters() have been set.

Returns, as a string, the code of the subroutine you can use to implement your custom character properties.

Takes an optional string argument; this is used for the subroutine name. Note that according to perlunicode the subroutine name has to start with In or Is. If this argument is omitted, a dummy name - InFoo - is used.

INSTALLATION
