[ANNOUNCE] Apache::IncludeHook

[Geoffrey Young]

hi all...

I wanted to let everyone know that I have ported <!-- #perl --> SSI tag 
support to Apache 2.0.  it should behave under both prefork and threaded 
mpms, and work pretty much the same as it did in Apache 1.3, despite the 
fact that mod_include is now an output filter.

while the support is fairly complete, the code is a bit messy and can be 
refactored.  however, I wanted to get something released for people to play 
with before I needed to move on to something else.

NAME

Apache::IncludeHook - #perl Server Side Include support

SYNOPSIS

  PerlModule Apache::IncludeHook

  Alias /ssi /usr/local/apache/htdocs
  <Location /ssi>
    AddType text/html .shtml
    AddOutputFilter INCLUDES .shtml
    Options +Includes
  </Location>
DESCRIPTION

Apache::IncludeHook offers support for #perl tags in
documents parsed by the mod_include engine included in
the Apache 2.0 distribution.  Supported formats include
  <!--#perl sub="My::PrintArgs" -->
  <!--#perl arg="fee" sub="My::PrintArgs" arg="fie" -->
  <!--#perl arg="foe" sub="My::PrintArgs::handler" -->
  <!--#perl arg="fum" sub="My::PrintArgs->method_handler" --> here
  <!--#perl arg="I smell" sub="sub { my $r = shift; print @_ }" -->
In Apache 1.3, mod_include supported #perl tags out of
the box.  In 2.0, support for tags outside the standard
mod_include realm ('echo', 'flastmod', etc) have been removed,
having been replaced with an API that allows you to hook
your own functionality into mod_include's parsing engine.
The 'exec' tag is an example of one that is no longer natively
supported by mod_include - mod_cgi now supplies the base
implementaiton of this tag.
The current hope with this module is simply to carry over #perl tag
support from Apache 1.3 to 2.0.  Apache::SSI-like support
for custom tags will (possibly come later).  keep in mind
that while this module is not inteneded to replace the old
Apache::SSI for Apache 1.3, because the new Apache 2.0 API
includes a filtering mechansim,
you already have the ability to post-process SSI tags via
Perl (or C) output filters.
EXAMPLE

  file.shtml:

    perl <!--#perl arg="one" sub="My::PrintArgs" --> here

  PrintArgs.pm:

    package My::PrintArgs;

    use Apache::RequestRec ();
    use Apache::Const -compile => 'OK';
    use strict;

    sub handler {

      my ($r, @args) = @_;

      print join ' ', '***', (join ' : ', @args), '***';

      return Apache::OK;
    }
which is almost identical to what you would see with mod_perl 1.0,
save the mod_perl 2.0 specific classes.
NOTES

This implementation is designed to hook into the mod_include
that ships with Apache 2.0.  It will not work with Apache 2.1.
This is alpha ware, subject to massive API changes.  Meaning,
the TIEHANDLE interface may go away and you may be forced to
use only the (currently non-existent) filter interface.  so
get to know filters now before it's too late (they're really
cool anyway).
FEATURES/BUGS

Subrequests are still a work in progress - they still don't seem
to work properly from filters.
only print STDOUT and $r->print are supported.  other methods
of sending content to the client still need to be implemented.
