Although this function (mw.util.wikiUrlencode) does "Encode page titles for use in a URL", it would be much more useful if it produced the same encoding as the MediaWiki parser does internally. For example, this would make it useful in jQuery selectors to select the <a> elements corresponding to particular page titles. Where the encodings do not match up, the selector will not find the element. One such discrepancy is, on Wikipedia, the parser converts the link [[union]] into the HTML code <a href="/wiki/Union">union</a>; but mw.util.wikiUrlencode("union") returns "union" (lowercase). Other inconsistencies: wikiUrlencode does not collapse multiple spaces/underscores (mw.util.wikiUrlencode("United States") returns "United___States", but the parser produces <a href="/wiki/United_States">United States</a>; wikiUrlencode converts (at least) the following characters to their percent-encoded equivalents, but the parser does not: !@$%^()=
There's a difference between normalization and encoding. the javascript mw.util.wikiUrlencode is to be compared to the PHP wfUrlencode() function. If those do not match up, then I'd say we've got a problem, but I don't believe that is the case. However, normalizing links is a different story. Such function doesn't exist in javascript yet. If we were to create such a function, it woudl be called by default in mw.util.wikiGetlink(), but not in mw.util.wikiUrlencode. Rephrasing bug title.
Changing case and normalizing series of spaces are part of title normalization -- not URL encoding. Depending on the site configuration, 'union' and 'Union' may refer to the same or to different articles, so they must not be encoded the same. To match wfUrlEncode() however, the treatment of some not-100%-reserved chars should be changed to match. wikiUrlencode currently attempts to specifically ensure that ':' and '/' are included raw, but none of the others. To match wfUrlEncode, should ensure that these are all left as-is: ';', '@', '$', '!', '*', '(', ')', ',', '/', ':'
To normalise a title, use the new mw.Title class. using: mediawiki.Title code: var t = mw.Title.newFromText('union _ stuff') t.getUrl(); // "/wiki/Union_stuff" This is the same as: using: mediawiki.Title, mediawiki.util code: var t = mw.Title.newFromText('union _ stuff') mw.util.wikiGetlink( t.toString() ); // "/wiki/Union_stuff"
