Check for missing dependencies only for activated modules

Since you can't activate modules without including their dependencies, perhaps this check shouldn't result in an error message. Error messages are sort of scary and imply that something needs fixing. In this case, unless you actually wanted to enable a module that was missing the dependency, nothing needs to be fixed. A notice would probably be sufficient. It might also be nice to add a note to the Status page using hook_requirements

Attached is a patch that makes these changes, as well as rewording the message to be less ominous.

I would love it if there was an option to turn off these notifications. If I am missing a dependency, I will find out soon enough when I go to install the module that depends on another. I don't like it when I go to a bunch of pages and get this error.

I absolutely love the module though - it's one of three modules I include in my installation package I have put together for every single site I build. I just don't like this one feature of it.

For those who want to disable this altogether:

The function that does this is called plugin_manager_missing_dependencies(). It is itself called in two other functions, plugin_manager_form_system_modules_alter() and plugin_manager_form_system_themes_alter().

So, to disable dependencies checking, open up plugin_manager.module and comment out lines 192-195:

$missing = plugin_manager_missing_dependencies();
if ($missing['#alert']){
    drupal_set_message(t("You have missing dependencies! ").l(t("Go here"),"admin/plugin_manager/deps").t(" to resolve them."),"error");
  }

...and lines 207-211:

$missing = plugin_manager_missing_dependencies();
if ($missing['#alert']){
    drupal_set_message(t("You have missing dependencies! ").l(t("Go here"),"admin/plugin_manager/deps").t(" to resolve them."),"error");
  }

I did this, with no ill effects thus far.

Glad to hear that! Will you be rolling out a new version soon?

Good luck!
