DESCRIPTION

This is extension of HTML::TagCloud.

This module allows you to register timestamp with tags. And color of tags will be changed according to it's timestamp.

Now, this doesn't depend on HTML::TagCloud.

TIMESTAMP

When you call 'add()' method, set timestamp as last argument.

    $cloud->add('perl','http://www.perl.org/', 20, '2005-07-15 00:00:00');

FORMAT

follow three types of format are allowed.

2005-07-15 00:00:00

2005/07/15 00:00:00

20050715000000

COLORS

This module chooses color from follow four types according to tag's timestamp.

earliest

earlier

later

latest

You needn't to set colors because the default colors are set already.

But when you want to set colors by yourself, of course, you can.

    my $cloud = HTML::TagCloud::Extended->new;

    $cloud->colors->set(
        earliest => '#000000',
    );

    $cloud->colors->set(
        earlier => '#333333',
        later   => '#999999',
        latest  => '#cccccc',
   );

    # or, you can set color for each attribute
    $cloud->colors->set(
        earliest => {
            link    => '#000000',
            hover   => '#CCCCCC',
            visited => '#333333',
            active  => '#666666',
        },
    );

LIMITTING

When you want to limit the amount of tags, 'html()', html_and_css()' need second argument as hash reference.

    $cloud->html_and_css( { order_by => 'timestamp_desc' , limit => 20 } );

SORTING TYPE

default is 'name'

name

name_desc

count

count_desc

timestamp

timestamp_desc

OTHER FEATURES

use_hot_color

set by size

    my $cloud = HTML::TagCloud::Extended->new(
        use_hot_color => 'size',
        hot_tags_size => 24,
    );

    # or set with accessor method

    my $cloud = HTML::TagCloud::Extended->new;

    $cloud->use_hot_color('size');
    $cloud->hot_tags_size(24);

Then, tags that's size is over 24 applys color for 'hot'. If you omit 'hot_tags_size', it'll be proper number automatically.

set by name

    my $cloud = HTML::TagCloud::Extended->new(
        use_hot_color => 'name',
        hot_tags_name => [ 'perl', 'ruby', 'python' ],
    );

    # or set with accessor method

    my $cloud = HTML::TagCloud::Extended->new;

    $cloud->use_hot_color('name');
    $cloud->hot_tags_name('perl', 'ruby', 'puthon');

You can alse change colors for 'hot' by yourself.

    $cloud->colors->set( hot => '#ff9900' );

    # or

    $cloud->colors->set(
        hot => {
            link    => '#000000',
            hover   => '#CCCCCC',

    # set as constructor's argument
    my $cloud = HTML::TagCloud::Extended->new(

    $cloud->base_font_size(30);
