MasonX::Interp::WithCallbacks 1.10

Greetings Fellow Masonites,

I have completed my conversion of my callback subclass from 
ApacheHandler to Interp. This means that the callbacks can be used in 
any Mason context, not just with mod_perl. 
MasonX::ApacheHandler::WithCallbacks is hereby deprecated, and will 
soon be deleted from CPAN (though you'll still be able to get it from 
BackPAN). Many thanks to the Mason development team for accepting my 
multitude of patches to make HTML::Mason::Interp more subclassable. A 
result of this change, however, is that MasonX::Interp::WithCallbacks 
requires Mason 1.23 or later.

I have also abstracted out all of the callback processing and execution 
code to a new module, Params::CallbackRequest. This enables me to keep 
the callback code independent of the Mason architecture, and thus work 
it in to other templating systems. Look for the addition of callbacks 
to Template Toolkit next! This change necessitated some breakage of 
backwards compatibility, but nothing that can't be changed with some 
simple regex work.

These modules are making their way to CPAN now, but you can get them 
here if you're impatient:

Here's a complete list of the changes to get you started:

1.10  Mon Sep  8 21:15:42 2003
       - Code moved over from MasonX::ApacheHandler::WithCallbacks, which
         is deprecated. Differences from that class are as follows.
       - Callback handling code from MasonX::ApacheHandler::WithCallbacks
         has been migrated to Params::CallbackRequest.
       - Code from MasonX::CallbackHandler has been migrated to
         Params::Callback.
       - MasonX::CallbackTester has been removed, since it isn't 
necessary
         in a non-mod_perl environment.
       - Params::CallbackRequest::Exceptions supplies the exceptions 
thrown
         by Params::CallbackRequest, since that module is not strictly
         connected to Mason.
       - Changed the request_args() accessor from MasonX::CallbackHandler
         to params() in Params::Callback, to reflect the idea that this 
is
         a generic parameter-triggered callback architecture.
       - Replaced the ah() accessor, since the callback controller isn't 
a
         Mason ApacheHandler anymore, with cb_request() in
         Params::Callback.
       - Added cb_request() accessor to MasonX::Interp::WithCallbacks.
       - Replaced the "exec_null_cb_values" parameter from
         MasonX::ApacheHandler::WithCallbaks, which had defaulted to 
true,
         with "ignore_nulls" in Params::CallbackRequest, which defaults 
to
         false.
       - Added Params::CallbackRequest notes() interface, which copies 
all
         notes to the Mason request notes() interface before the request
         executes.

Enjoy!

David
