[lahwaacz]

• canonicalize (first letter case, underscores to spaces)
• percent-decoding for page titles (e.g. [[GTK%2B]] → [[GTK+]])
• wrapper class for its {{DISPLAYTITLE}}, {{PAGENAME}}, {{FULLPAGENAMEE}}, {{BASEPAGENAMEE}}, {{SUBPAGENAMEE}}, {{SUBJECTPAGENAMEE}}, {{TALKPAGENAMEE}}, {{ROOTPAGENAME}} attributes
  • https://www.mediawiki.org/wiki/Help:Magic_words#Page_names
  • http://pythonhosted.org/mediawiki-utilities/lib/title.html#mw-lib-title
  • implemented in ws.parser_helpers.title
• handle leading colon (should be automatic for categories and files/images)
• double colons, e.g. [[wikipedia::Help:Editing]] -> [[wikipedia:Help:Editing]]
• method to detect namespace
• handle namespace aliases
• handle relative links: [[/bar]] on page foo should be equivalent to [[foo/bar]]
