Re: [cgiapp] [PATCH] added hook

[Stephen Howard]

I know this isn't a CGI::App based solution for your problem, but 
consider WWW::Pipeline's (a subclass of Application::Pipeline) solution 
to adding a new hook.  It's as simple as adding entries to an array in 
the appropriate slot of a hash called the %plan.  Here's the superclass' 
plan:

our %plan = (
   Initialization => [ \&_setup ],
   Teardown => [ \&_closeSession ]
);
And here's the subclass' plan:
our %plan = (
   Initialization => [ 'SUPER', \&_setup ],
   ParseRequest   => [ \&_parseRequest, \&_authRequest ],
);
When both the superclass and subclass have methods for a certain phase 
of the plan, the SUPER keyword in the subclass indicates where to inject 
the superclass' methods into the phase.  Leaving that keyword out means 
that the subclass intends to replace the superclass' methods rather than 
supplement them, for that phase.  A phase not in the subclass but in the 
superclass will be executed as specified by the superclass, unless the 
subclass explicitly sets an empty arrayref for that phase.

Using the RunMode plugin gives most of the application development under 
WWW::Pipeline a very CGI::App feel.
