Library to get and put pages on a MediaWiki.
Contents of the library (objects and functions to be used outside, situation
late August 2004)
Classes:
Page: A MediaWiki page
__init__ : Page(Site, Title) - the page with title Title on wikimedia site Site
title : The name of the page, in a form suitable for an interwiki link
urlname : The name of the page, in a form suitable for a URL
titleWithoutNamespace : The name of the page, with the namespace part removed
section : The section of the page (the part of the name after '#')
sectionFreeTitle : The name without the section part
aslink : The name of the page in the form [[Title]] or [[lang:Title]]
site : The wiki this page is in
encoding : The encoding of the page
isAutoTitle : If the title is a well known, auto-translatable title
autoFormat : Returns (dictName, value), where value can be a year, date, etc.,
and dictName is 'YearBC', 'December', etc.
isCategory : True if the page is a category, false otherwise
isImage : True if the page is an image, false otherwise
get (*) : The text of the page
exists (*) : True if the page actually exists, false otherwise
isRedirectPage (*) : True if the page is a redirect, false otherwise
isEmpty (*) : True if the page has 4 characters or less content, not
counting interwiki and category links
botMayEdit (*) : True if bot is allowed to edit page
interwiki (*) : The interwiki links from the page (list of Pages)
categories (*) : The categories the page is in (list of Pages)
linkedPages (*) : The normal pages linked from the page (list of Pages)
imagelinks (*) : The pictures on the page (list of ImagePages)
templates (*) : All templates referenced on the page (list of strings)
getRedirectTarget (*) : The page the page redirects to
isDisambig (*) : True if the page is a disambiguation page
getReferences : List of pages linking to the page
namespace : The namespace in which the page is
permalink (*) : The url of the permalink of the current version
move : Move the page to another title
put(newtext) : Saves the page
put_async(newtext) : Queues the page to be saved asynchronously
delete : Deletes the page (requires being logged in)
(*) : This loads the page if it has not been loaded before; permalink might
even reload it if it has been loaded before
Site: a MediaWiki site
messages : There are new messages on the site
forceLogin() : Does not continue until the user has logged in to
the site
getUrl() : Retrieve an URL from the site
mediawiki_message(key): Retrieve the text of the MediaWiki message with
the key "key"
has_mediawiki_message(key) : True if this site defines a MediaWiki message
with the key "key"
Special pages:
Dynamic pages:
allpages(): Special:Allpages
newpages(): Special:Newpages
longpages(): Special:Longpages
shortpages(): Special:Shortpages
categories(): Special:Categories
Cached pages:
deadendpages(): Special:Deadendpages
ancientpages(): Special:Ancientpages
lonelypages(): Special:Lonelypages
uncategorizedcategories(): Special:Uncategorizedcategories
uncategorizedpages(): Special:Uncategorizedpages
unusedcategories(): Special:Unusuedcategories
Other functions:
getall(): Load pages via Special:Export
setAction(text): Use 'text' instead of "Wikipedia python library" in
editsummaries
handleArgs(): Checks whether text is an argument defined on wikipedia.py
(these are -family, -lang, -log and others)
translate(xx, dict): dict is a dictionary, giving text depending on language,
xx is a language. Returns the text in the most applicable language for
the xx: wiki
setUserAgent(text): Sets the string being passed to the HTTP server as
the User-agent: header. Defaults to 'Pywikipediabot/1.0'.
output(text): Prints the text 'text' in the encoding of the user's console.
input(text): Asks input from the user, printing the text 'text' first.
showDiff(oldtext, newtext): Prints the differences between oldtext and newtext
on the screen
getLanguageLinks(text,xx): get all interlanguage links in wikicode text 'text'
in the form xx:pagename
removeLanguageLinks(text): gives the wiki-code 'text' without any interlanguage
links.
replaceLanguageLinks(oldtext, new): in the wiki-code 'oldtext' remove the
language links and replace them by the language links in new, a dictionary
with the languages as keys and either Pages or titles as values
getCategoryLinks(text,xx): get all category links in text 'text' (links in the
form xx:pagename)
removeCategoryLinks(text,xx): remove all category links in 'text'
replaceCategoryLinks(oldtext,new): replace the category links in oldtext by
those in new (new a list of category Pages)
stopme(): Put this on a bot when it is not or not communicating with the Wiki
any longer. It will remove the bot from the list of running processes,
and thus not slow down other bot threads anymore.
