you may use -namespace Option which is already implemented and comes from pagegenerators

-namespace is useful when running for some list of pages (usage of template).
But when running on -namespace:10 or 4 or 100, bot should auto skip subpages

(but not all pages with "/" are subpages (e.g. Template:NHL 2014/15), so when running from -file: bot shoud create these pages too)

Patch for accidenatlly created userpages

When I accidentally forgot to add -namespace:0, bot should'nt create new items for userpages

(note:there is change of default dates too, I am not very familiar with creating patches, so I left it in patch too)

Disallow creating items for all subpages

You may use our Gerrit uploaded script for patches. I'll have a look on your attachment soon.

-1 on the patch, you should use -namespace for that.

For the subpages we should probably have another filter pagegenerator so that this functionality is available for all programs.
