[drupal-devel] [feature] Dependency system to solve forum without comment problem

[javanaut]

Issue status update for http://drupal.org/node/18447

 Project:      Drupal
 Version:      cvs
 Component:    system.module
 Category:     feature requests
 Priority:     normal
 Assigned to:  chx
 Reported by:  chx
 Updated by:   javanaut
 Status:       patch

I think allowing for both required dependencies as well as optional ones
would make it practical for a package management tool to be created.  I
like it, though, and I think being able to programatically enforce (or
at least notify users about) dependencies would assist users who refuse
to RTFM.
>From my drupal-devel comment, here's how I would suggest formatting the
hook_depends:

<?php
function filestore2_depends() {
 return array('required'=>array('fscache'),
'optional'=>array('taxonomy','comments'));
}
?>

As discussed on the developer list. This was surprisingly easy. There is
still an issue: t('The configuration options have been saved.') is
displayed more than once if there is a dependency forced module switch
on. I have tried something (you'll see) for some reason it does not
work. 
Number of page reloads can be decreased if Drupal could be
reinitialized after system_listing_save instead of redirecting but I
doubt this would be feasible.
Although I marked this is feature request, this is more a usability
issue (for the forum-comment dependency) and as a side effect it is a
useful feature, too (for any other module "bundles").
I want criticism! I'd like to get torn apart by wild animals. Heavy! 
Eaten by some squirrels.

Forgive me if I'm mistaken, but shouldn't forum_depends return an array?
