Handbuch:Pywikibot/pagegenerators.py

pagegenerators.py is a Handbuch:Pywikibot script used to generate list of pages for other scripts.

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

Command line usage

The pagegenerators.py may not be executed directly. Instead, the script listpages.py can be used.

Beispiel:

$ python pwb.py listpages -search:'foobar'

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

Siehe listpages.py für mehr Details.

Calls from another script

Category crawler:

from pywikibot import pagegenerators

site = pywikibot.Site()
cat = pywikibot.Category(site, 'Category name')
pages = cat.articles()
for page in pagegenerators.PreloadingGenerator(pages, 100):
    # some treatment of generated pages

Subcategories explorer:

gen = pagegenerators.CategorizedPageGenerator(cat, recurse=True)

MySQL requests (see Handbuch:Pywikibot/MySQL ):

gen = pagegenerators.MySQLPageGenerator(query)

Unicode-Empfehlung

The following code returns KeyError: 'query' because of the special character:

gen = pagegenerators.SearchPageGenerator('´', namespaces = [0])

If searching in user and mediawiki namespaces, it would look like

gen = pagegenerators.SearchPageGenerator('´', namespaces = [2, 8])

Consequently, an encoding conversion is needed:

gen = pagegenerators.SearchPageGenerator("´", namespaces = [0])
