@neo.........regarding your original post#1, if the scroll bars have now been removed what will happen if someone posts a very wide or very long code segment within code tags? If there are no scroll bars at all will the display look right and will all the code be able to be viewed?

template::declare::tagset
Template::Declare::TagSet(3pm) User Contributed Perl Documentation Template::Declare::TagSet(3pm)
NAME
Template::Declare::TagSet - Base class for tag sets used by Template::Declare::Tags
SYNOPSIS
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;
}
DESCRIPTION
Template::Declare::TagSet is the base class for declaring packages of Template::Delcare tags. If you need to create new tags for use in
your templates, this is the base class for you! Review the source code of Template::Declare::TagSet::HTML for a useful example.
METHODS
new( PARAMS )
my $tag_set = Template::Declare::TagSet->new({
package => 'Foo::Bar',
namespace => undef,
});
Constructor created by "Class::Accessor::Fast", accepting an optional hash reference of parameters.
get_tag_list
my $list = $tag_set->get_tag_list();
Returns an array ref for the tag names offered by a tag set.
get_alternate_spelling( TAG )
$bool = $obj->get_alternate_spelling($tag);
Returns true if a tag has an alternative spelling. Basically it provides a way to work around naming conflicts. For example, the "tr" tag
in HTML conflicts with Perl's "tr" operator, and the "template" tag in XUL conflicts with the "template" sub exported by
"Template::Declare::Tags".
can_combine_empty_tags( TAG )
$bool = $obj->can_combine_empty_tags($tag);
Specifies whether "<tag></tag>" can be combined into a single token, "<tag />". By default, all tags can be combined into a single token;
override in a subclass to change this value where appropriate. For example,
"Template::Declare::TagSet::HTML->can_combine_empty_tags('img')" returns true since "<img src="..." />" is always required for HTML pages.
"Template::Declare::TagSet::HTML->can_combine_empty_tags('script')", on the other hand, returns false, since some browsers can't handle a
single script token.
ACCESSORS
This class has two read-only accessors:
package
my $package = $obj->package();
Retrieves the value of the "package" option set via the constructor.
namespace
my $namespace = $obj->namespace();
Retrieves the value of the "namespace" option set via the constructor.
