Wapiti

A MediaWiki API wrapper in Python for humans and elk.

Wapiti makes it simple for python scripts to retrieve data from the Wikipedia API. No more worries about query limits, continue strings, or formatting. Just ask for data and get structured results.

Example

Let's get the members of Wikipedia's Category:Lists of superlatives. First, initialize a WapitiClient and change any settings. Next, run the operation get_category_pages on the category 'Lists of superlatives', with a limit of 10:

>>> import wapiti
>>> client = wapiti.WapitiClient('domas@mituzas.lt')
>>> client.get_category_articles_recursive('Lists of superlatives', 10))
[PageInfo(title=u'The Fifty Worst Films of All Time', page_id=1820513, ns=0),
 PageInfo(title=u"World's busiest city airport systems by passenger traffic", page_id=33167241, ns=0),
 PageInfo(title=u'List of oldest Major League Baseball players', page_id=1947309, ns=0),
 PageInfo(title=u'List of firsts in India', page_id=3752148, ns=0),
 PageInfo(title=u'List of the first female holders of political offices in Europe', page_id=18904865, ns=0),
 PageInfo(title=u'List of the busiest airports in the Republic of Ireland', page_id=26712480, ns=0),
 PageInfo(title=u'List of longest bridges above water in India', page_id=32312925, ns=0),
 PageInfo(title=u'List of the busiest airports in China', page_id=33396262, ns=0),
 PageInfo(title=u'List of most common surnames in Asia', page_id=26810011, ns=0),
 PageInfo(title=u'List of largest mosques', page_id=20897194, ns=0)]

This returns a list of PageInfo objects for the category's members.

Operations

Operations usually take two positional arguments: the query_param (page, category, template, etc.), and limit (maximum number of results).

  • get_random(limit) : returns a list of PageIdentifiers for random pages.
  • get_category_articles(category, limit) : returns a list of PageIdentifiers for the articles or talk pages in a category. If you are interested in getting pages beyond of the main and talk namespace, try get_category.
  • get_category_articles_recursive(category, limit) : returns a list of PageInfos for the articles in a category and its subcategories. If you are interested in getting pages beyond of the main and talk namespace, try get_category_recursive.
  • get_transcludes(page, limit) : returns a list of PageIdentifiers for the articles that embed (transclude) a page. For example, see the pages that embed Template:Infobox with client.get_transcludes('Infobox').
  • get_backlinks(page, limit) : returns a list of PageIdentifiers for pages that internally link back to a page. For example, see the pages that link to 'Coffee' with client.get_backlinks('Coffee').
  • get_revision_infos(page, limit) : returns a list of RevisionInfos for a page's revisions.
  • get_current_content(page, limit) : returns a list of Revisions (including text content) for the page's most recent revisions.

Other operations are available: see wapiti/operations

Models

Models describe the structure for result data. For the full list of models, see wapiti/operations/models.py

PageIdentifier

A PageIdentifier describes the standard information available for a page.

  • Title : unique name of the page
  • ID : the primary key for the page
  • Namespace : the namespace number, which can indicate whether the page is an article, discussion page, user page, template, category, etc.
  • Source : the MediaWiki API where this page was retrieved
  • Normalized title : the title may have been normalized by MediaWiki, for example, by resolving a redirect
  • Subject ID : the ID of the corresponding page in the basic namespace
  • Talk page ID : the ID of the corresponding page in the talk namespace

RevisionInfo

A RevisionInfo describes the standard information for a revision.

  • PageIdentifier : the page's PageIdentifier
  • Subject revision ID : the primary key for a revision
  • Parent revision ID : the previous revision to the page
  • User text : the editor's username, or IP address for an unregistered user
  • User ID : the unique id of the user who submitted this revision. It may be 0 for an unregistered user.
  • Size : the length of the article at this revision
  • Timestamp : timestamp in UTC when this revision was submitted
  • SHA1 : the SHA-1 hash of revision text in base-36.
  • Edit summary : the edit summary (or 'comment') for a contribution. In some cases, it may have been deleted (or 'oversighted') and unavailable through the API.
  • Tags : brief messages that MediaWiki (or an extension) may automatically place next to certain edits. Tags are not common, usually placed by Edit Filter or VisualEditor extensions.
  • Parsed : whether the page is parsed (html) or not (wikitext)

Revision

A Revision includes the same data as RevisionInfo, plus full text content.

TODO

  • Logging
  • Client settings
  • Port more API calls
  • Retry and timeout behaviors
  • Get my shit together and continue work on the HTTP client.
  • Underscoring args
  • Pause/resume
  • Better differentiation between the following error groups:
    • Network/connectivity
    • Logic
    • Actual Mediawiki API errors ('no such category', etc.)
  • Relatedly: Save MediaWiki API warnings
  • Types of API calls:
    • single argument -> multiple results (get category)
    • many arguments -> up to one result per argument (get protections)
    • multiple arguments -> multiple results per argument (get language links)
    • TODO: establish return format convention for this
  • Need generic support for:
    • APIs which support both pageid and title lookup
    • Redirect following
  • Full docs
