HTML::AsSubs, released August 31, 2017
as part of HTML-Tree.

.SH "DESCRIPTION"
.IX Header "DESCRIPTION"
This module exports functions that can be used to construct various
\&\s-1HTML\s0 elements. The functions are named after the tags of the
corresponding \s-1HTML\s0 element and are all written in lower case. If the
first argument is a hash reference then it will be used to initialize the
attributes of this element. The remaining arguments are regarded as
content.
.PP
For a similar idea (i.e., it's another case where the syntax tree
of the Perl source mirrors the syntax tree of the \s-1HTML\s0 produced),
see HTML::Element's \f(CW\*(C`new_from_lol\*(C'\fR method.
.PP
For what I now think is a cleaner implementation of this same idea,
see the excellent module \f(CW\*(C`XML::Generator\*(C'\fR, which is what I suggest
for actual real-life use. (I suggest this over \f(CW\*(C`HTML::AsSubs\*(C'\fR and
over \f(CW\*(C`CGI.pm\*(C'\fR's HTML-making functions.)

\& sub html { my($type)=shift; bless ["<$type>", @_, "</$type>"]; }

\&
\& p.s. If you didn\*(Aqt get it, think about recursive data types: html(html())
\& p.p.s. I\*(Aqll turn this into a much more practical example in a day or two.
\& p.p.p.s. It\*(Aqs a pity that overloads are not inherited. Is this a bug?

.SH "BUGS"
.IX Header "BUGS"
The exported \fIlink()\fR function overrides the builtin \fIlink()\fR function.
The exported \fItr()\fR function must be called using &tr(...) syntax
because it clashes with the builtin tr/../../ operator.

The \fI_elem()\fR function is wrapped by all the html 'tag' functions. It
takes a tag-name, optional hashref of attributes and a list of content
as parameters.
