HTML::Subtext Version 1.03
Sun Mar  7 14:16:53 PST 1999

    This module is designed to do simple textual substitutions into an
    HTML template document in an "offline" process. It is *not* a
    mechanism for implementing server-side includes -- there are plenty of
    other perl modules that do that. There are also other modules which
    let you embed arbitrary perl expressions in a template. [These are
    quite powerful and useful, but assume a certain sophistication on the
    part of the template author.] HTML::Subtext doesn't do that either.

    What it does do is allow you to compose an HTML document using your
    favorite WYSIWYG HTML editor, include place-holder strings in it like
    "Customer's name here", and then turn those place holders into a
    substitution field by making the text a link to a special 'subtext:'
    URI. This approach has the following advantages:

      1. Any Web server can display the finished documents -- you don't
         need special support for server-side includes, or active server
         pages, or anything beyond plain vanilla HTML. (Of course it is
         still possible to use those features if you have and want them.)
      2. The templates are easy for a non-technical user to prepare
         (in particular a non-perl-literate user).
      3. It's possible to view the template in its unprocessed form, in a
         regular Web browser, and to see where the substituted strings
         will be placed and approximately what your finished document
         will look like.
      4. The substitution mechanism is robust against errors in the
         template specification. That is, the output is still a valid
         HTML document even if some of the substitution field names are
         misspelled or invalid.

    In short, the idea is to make things as simple and convenient as
    possible from the perspective of the template author. I looked through
    a lot of HTML manipulation packages on CPAN, but none of them struck
    me as having quite this goal in mind. [Perhaps this is because the very
    idea of using a template is that you only have to get it right once,
    so power and versatility are more important than convenience. But for
    the particular application I was building at the time, there were a
    number of templates to be built, and they were to be tweaked fairly
    regularly.]

INSTALLATION

    Installation is accomplished in the usual manner-- unpacking the tar
    archive should create a directory called HTML-Subtext-1.03/. cd into
    this directory and issue the following commands:

      perl Makefile.PL
      make
      make test

    Assuming all the tests succeed, you may require root or administrator
    privledges on your system for the final step:

      make install

    It's possible to make use of the module without installing it. See the

ACKNOWLEDGEMENTS

    The implementation of this module was almost trivially simple, thanks
    to the excellent work of Gisle Aas (and others) on the HTML::Parser
    and URI modules.

NAME
    HTML::Subtext - Perform text substitutions on an HTML template

SYNOPSIS
      use HTML::Subtext;
      %context = ( ... ); # Hash of names to substitution text
      $p = HTML::Subtext->new('CONTEXT' => \%context);
      $p->parse_file("template.html");

DESCRIPTION
    `HTML::Subtext' is a package for performing text substitutions
    on a specially formatted HTML template. The template uses normal
    HTML markup, but includes links of the form:

      <a href="subtext:foo/bar">This text will be replaced</a>

    The URI in this link tells `HTML::Subtext' to check in the
    provided hash `'CONTEXT'' for a key named `'foo/bar''. If this
    lookup succeeds in producing a string value, the text in the
    body of the link is replaced by that value.

EXAMPLES
    This example performs substitutions into a template embedded
    into the Perl code as a *here-document*.

      use HTML::Subtext;

      %context = (
        'author/name' => 'Kaelin Colclasure',

      );

      $p = HTML::Subtext->new('CONTEXT' => \%context);
      $p->parse(<<EOT);
      <html><head><title>example</title></head><body>
      <a href=\"subtext:author/name\">Author's name here</a>
      <a href=\"subtext:author/email\">mailto: link here</a>
      </body></html>
      EOT

    When run, the example produces the following output:

      <html><head><title>example</title></head><body>
      Kaelin Colclasure

      </body></html>
