Manual talk:Pywikibot/weblinkchecker.py/LQT Archive 1

Future feature
It would be pretty neat if one day this could also check whether a page is saved in the Internet Archive (which should be pretty easy to do, since all you have to do is append the page's address which you are checking to "http://web.archive.org/web/", and see whether it returns "$PAGE is not available in the Wayback Machine.").

Even neater would be if one could take a positive result and have the bot automatically insert in the article a link to the most recent archived copy, but that would not be as easy. --129.21.121.171 21:16, 10 May 2006 (UTC)

Is it possible to feed the output from this into the replace.py or some other script? ST47 19:02, 6 December 2006 (UTC)

Environment proxy variables (http_proxy, no_proxy) support
Weblinkchecker now uses httplib which does not honor environment proxy variables http_proxy, no_proxy. So if you are behind a proxy and your wiki is NOT in the outer world, there is no way to check the links normally. Here's a patch which adds the support for these variables, though the resulting proxy support is very buggy - works only in Python 2.6 with your wiki address first in no_proxy variable, like no_proxy="www.wiki.local, *.local" It would be great to merge this patch (or its fixed version) into your SVN...

Is anyone else getting this error a lot? I am using MediaWiki v1.16.0beta. Thanks, Tisane 22:24, 7 April 2010 (UTC)

Title encoding
Could we change the title encoding? For example, to report a URL in the page qualimétrie, the .txt contains "qualimÃ©trie". JackPotte 17:24, 14 August 2010 (UTC)
