NAME ^

Apache::SimpleReplace - a simple template framework

SYNOPSIS ^

httpd.conf:

 <Location /someplace>
    SetHandler perl-script
    PerlHandler Apache::SimpleReplace

    PerlSetVar  TEMPLATE "/templates/format1.html"
    PerlSetVar  REPLACE "the content goes here"
 </Location>  

Apache::SimpleReplace is Filter aware, meaning that it can be used within an Apache::Filter framework without modification. Just include the directive

  PerlSetVar Filter On

and modify the PerlHandler directive accordingly. As of version 0.06, Apache::SimpleReplace requires Apache::Filter 1.013 or better - users of Apache::Filter 1.011 or less should use version 0.05.

DESCRIPTION ^

Apache::SimpleReplace provides a simple way to insert content within an established template for uniform content delivery. While the end result is similar to Apache::Sandwich, Apache::SimpleReplace offers several advantages.

  o It does not use separate header and footer files, easing the
    pain of maintaining syntactically correct HTML in seperate files.

  o It is Apache::Filter aware, thus it can both accept content from
    other content handlers as well as pass its changes on to others
    later in the chain.

EXAMPLE ^

/usr/local/apache/templates/format1.html:

  <html>
      <head><title>your template</title></head>
              <title>your template</title>
      <body bgcolor="#778899">
              some headers, banners, whatever...
              <p>
  the content goes here
              </p>
              <p>some footers, modification dates, whatever...
      </body>
  </html> 

 httpd.conf:

  <Location /someplace>
     SetHandler perl-script
     PerlHandler Apache::SimpleReplace Apache::SSI

     PerlSetVar  TEMPLATE "templates/format1.html"
     PerlSetVar  REPLACE "the content goes here"
     PerlSetVar  Filter On
  </Location>

Now, a request to http://localhost/someplace/foo.html will insert the contents of foo.html in place of "the content goes here" in the format1.html template and pass those results to Apache::SSI The result is a nice and tidy way to control any custom headers, footers, background colors, or images in a single html file.

NOTES ^

As of 0.02, TEMPLATE is no longer relative to the ServerRoot.

REPLACE defaults to "|", though it may be any character or string you like - metacharacters are disabled in the search, so sorry, no regex for now...

Verbose debugging is enabled by setting $Apache::SimpleReplace::DEBUG=1 or greater. To turn off all debug information, set your apache LogLevel directive above info level.

This is alpha software, and as such has not been tested on multiple platforms or environments. It requires PERL_LOG_API=1, PERL_FILE_API=1, and maybe other hooks to function properly.

FEATURES/BUGS ^

If Apache::SimpleReplace finds more than one match for REPLACE in the template, it will insert the request for the first occurrence only. All other replacement strings will just be stripped from the template.

Currently, Apache::SimpleReplace will return DECLINED if the content-type of the request is not 'text/html'.
