Hi,
I am wondering if anyone has experience with a framework for
dynamically loading certain modules into an application and executing
certain code based on whether a certain module is loaded (available or
not). By "dynamically", I do not mean loading run-time, only being
able to safely exclude certain modules at startup. One place this
could come in handy is when selling an app to 2 clients of whom one
has purchased all the functionality and the other has not, and you
don't want to give them certain module(s). I am guessing one could
accomplish this by using a macro processor (m4) to preprocess Perl
code before it's "released", but it would probably be somewhat
painful.
Actually I dont' think the m4 idea is so bad, you could probably just have it
stub out the packages
package A;
1;
and change your code to do ::can() or ->can() as appropriate.
I can't think of another way, that will keep the "conditional" code shared for
those that bought it all.
