lib::HTML::AsSuUser)Contributed Perl Documentlib::HTML::AsSubs(3)NAMEHTML::AsSubs - functions that construct a HTML syntax tree
SYNOPSIS
use HTML::AsSubs;
$h = body(
h1("This is the heading"),
p("This is the first paragraph which contains a ",
a({href=>'link.html'}, "link"),
" and an ",
img({src=>'img.gif', alt=>'image'}),
"."
),
);
print $h->as_HTML;
DESCRIPTION
This module exports functions that can be used to
construct various HTML elements. The functions are named
after the tags of the correponding HTML element and are
all written in lower case. If the first argument is a hash
then it will be used to initialize the attributes of this
element. The remaining arguments are regarded as content.
ACKNOWLEDGEMENT
This module was inspired by the following message:

Subject: Wow! I have a large lightbulb above my head!
Take a moment to consider these lines:
%OVERLOAD=( '""' => sub { join("", @{$_[0]}) } );
sub html { my($type)=shift; bless ["<$type>", @_, "</$type>"]; }
:-) I *love* Perl 5! Thankyou Larry and Ilya.

Tim Bunce.
p.s. If you didn't get it, think about recursive data types: html(html())
p.p.s. I'll turn this into a much more practical example in a day or two.
p.p.p.s. It's a pity that overloads are not inherited. Is this a bug?
BUGS
The exported link() function overrides the builtin link()
function. The exported tr() function must be called using
&tr(...) syntax because it clashes with the builtin
tr/../../ operator.
