Negation of page generators
Open, LowPublic


It would be nice if it was possible to negate page generators, in order to have the scripts operate on all pages that do not match a given page generator.

I think the syntax -no-pagegenerator would be good for that. There are some page generators for which negation does not seem to make sense (like -randomredirect), but many for which it could be useful (-no-usercontribs, -no-lonelypages, -no-transclude, -no-titleregex, -no-grep, -no-page and others).

One use case discussed on IRC was excluding certain namespaces. (all pages except namespace 0) -- any implementation of that will need to ensure it does not exceed the limit of namespaces and reintroduce T67981: WARNING: API warning (categorymembers): Too many values supplied for parameter 'gcmnamespace': the limit is 50.

Another idea would be to allow a filter mechanism like the implementation inside EventStreams.
