=head1 NAME
Template::Plugin::HTML - Plugin to create HTML elements
=head1 SYNOPSIS
[% USE HTML %]
[% HTML.escape("if (a < b && c > d) ..." %]
[% HTML.element(table => { border => 1, cellpadding => 2 }) %]
[% HTML.attributes(border => 1, cellpadding => 2) %]
=head1 DESCRIPTION
The C plugin is a very basic plugin, implementing a few useful
methods for generating HTML.
=head1 METHODS
=head2 escape(text)
Returns the source text with any HTML reserved characters such as
C>, C>, etc., correctly escaped to their entity equivalents.
=head2 attributes(hash)
Returns the elements of the hash array passed by reference correctly
formatted (e.g. values quoted and correctly escaped) as attributes for
an HTML element.
=head2 add_attribute(attributes)
This provides a way to incrementally add attributes to the object.
The values passed in are stored in the object. Calling
L with just a tag or L without an parameters
will used the saved attributes.
USE tag = HTML;
tag.add_attributes( { class => 'navbar' } );
tag.add_attributes( { id => 'foo' } );
tag.add_attributes( { class => 'active' } );
tag.element( 'li' ); #
This method has two aliases: add_attribute() and add().
=head2 replace_attribute(attributes)
This will replace an attribute value instead of add to existing.
USE tag = HTML;
tag.add_attributes( { class => 'navbar' } );
tag.add_attributes( { id => 'foo' } );
tag.replace_attributes( { class => 'active' } );
tag.element( 'li' ); #
This method has two aliases: replace_attribute() and replace().
=head2 clear_attributes
Clears any saved attributes
=head2 element(type, attributes)
Generates an HTML element of the specified type and with the attributes
provided as an optional hash array reference as the second argument or
as named arguments.
[% HTML.element(table => { border => 1, cellpadding => 2 }) %]
[% HTML.element('table', border=1, cellpadding=2) %]
[% HTML.element(table => attribs) %]
=head1 DEBUGGING
The HTML plugin accepts a C option as a constructor argument
which, when set to any true value, causes the attributes generated by
the C method (either directly or via C) to be
returned in sorted order. Order of attributes isn't important in
HTML, but this is provided mainly for the purposes of debugging where
it is useful to have attributes generated in a deterministic order
rather than whatever order the hash happened to feel like returning
the keys in.
[% USE HTML(sorted=1) %]
[% HTML.element( foo => { charlie => 1, bravo => 2, alpha => 3 } ) %]
