Re: [cgi-prototype-users] Using multiple base classes for an app

[Andrew G. <ag...@bu...>]

Shortly after posting this, I thought of another, simpler solution (perhaps
along the lines of what you are suggesting), which is a little more explicit
and maybe a little easier to understand and support. But I wanted to see if
I received any feedback before muddying the waters by answering my own
question.

It should be (theoretically) simple enough to create a page module for the
page that borrows functionality and simply add the module of the class I
need the functionality from to the use base statement, a la:

use base qw( Project2::App::borrowed_page Project1::App );

Then as long as I put hooks into my primary methods of
Project2::App::borrowed_page I can easily reuse and modify the
functionality.

That said, and I don't purport to be an OO expert, my understanding of
CGI::Prototype is that it is intended to be an OO framework, which means
that it inherently makes sharing functionality easier. In OO perl, this is
still just through the use of use base statements, and my proposal was to
augment the framework by having the module perform that use base for me
automagically.
