NAME
Template::Declare::TagSet - Base class for tag set classes used by Template::Declare::TagsSYNOPSIS
package My::TagSet; use base 'Template::Declare::TagSet'; # returns an array ref for the tag names sub get_tag_list { [ qw/ html body tr td table base meta link hr / ] } # prevents potential naming conflicts: sub get_alternate_spelling { my ($self, $tag) = @_; return 'row' if $tag eq 'tr'; return 'cell' if $tag eq 'td'; } # Specifies whether "<tag></tag>" can be # combined to "<tag />": sub can_combine_empty_tags { my ($self, $tag) = @_; $tag =~ /^ base | meta | link | hr $/x; }
METHODS
- "$obj = Template::Declare::TagSet->new({ package => 'Foo::Bar', namespace => undef });"
- Constructor created by "Class::Accessor::Fast", accepting an optional option list.
- "$list = $obj->get_tag_list()"
- Returns an array ref for the tag names.
- "$bool = $obj->get_alternate_spelling($tag)"
- Returns whether a tag has an alternative spelling. Basically it provides a way to work around naming conflicts, for examples, the "tr" tag in HTML conflicts with the "tr" operator in Perl and the "template" tag in XUL conflicts with the "template" sub exported by "Template::Declare::Tags".
- "$bool = $obj->can_combine_empty_tags($tag)"
- Specifies whether ``<tag></tag>'' can be combined into a single token ``<tag />''.
Always returns true (value 1) in this base class.
But there's some cases where you want to override the deafault implementation. For example, "Template::Declare::TagSet::HTML->can_combine_empty_tags('img')" returns true (1) since "<img src="..." />" is always required for HTML pages.
ACCESSORS
This class has two read-only accessors:- "$obj->package()"
- Retrieves the value of the "package" option set via the constructor.
- "$obj->namespace()"
- Retrieves the value of the "namespace" option set by the constructor.
