Manual:Pywikibot/pagegenerators.py/en

pagegenerators.py can generate a list of pages.

This module offers a wide variety of page generators. A page generator is an object that is iterable (see http://www.python.org/dev/peps/pep-0255/) and that yields page objects on which other scripts can then use.

Command line usage
The compat version of pagegenerators.py may be executed directly, for testing purposes.

Example:

This will return, in standard output, a list of all pages containing "foobar," as returned by MediaWiki's search engine.

The core version of pagegenerators.py may not be executed directly. Instead, the script is used.

Example:

This will also return, in standard output, a list of all pages containing "foobar," as returned by MediaWiki's search engine.
