How to get a list of all users having contributed to the current page shown on page

If you can get away with only supporting MSIE users, you could do it with an ActiveX control: http://www.outlookcode.com/article.aspx?id=70

This requires all users to have MSIE and Outlook installed on their local computers. Everyone must also have access to the calendar being displayed.

I often need something like this as well, but it looks like there's no ready solution.

What I've done is written a script that helps me grab revisions using the MediaWiki API and import them to the Bazaar version control system. bzr qblame article.wiki, then gives a nice view of who changed what. The script is not really ready for release, but you can find it below or on Pastebin. The script adds to a mercurial repo, which can then be converted to Bazaar.

# I hereby place this script into the Public Domain!
import os, sys
import time

import mwclient

import mercurial.ui
from mercurial import localrepo
from mercurial import commands

article = 'Love'
#start_time = None
start_time = '2011-01-01T00:00:00Z'

# set up mercurial repo
ui = mercurial.ui.ui()
repo_dir = article
repo = localrepo.localrepository(ui, path=repo_dir, create = not os.path.isdir(repo_dir))
#if not os.path.isdir(article):
#   os.mkdir(article)
#os.chdir(article)
print "rep in", repo.root
content_path = os.path.join(repo.root, article + '.wiki')

site = mwclient.Site('en.wikipedia.org')
page = site.Pages[article]

for rev in page.revisions(start=start_time, limit=50,dir='newer', prop='ids|timestamp|flags|comment|user|content'):
    content = rev['*']
    timestamp = time.asctime(rev['timestamp'])
    comment = rev['comment'].encode('utf8')
    if len(comment) == 0: comment = "blank"
    print "writing revision from", timestamp

    f = open(content_path, 'wb')
    f.write(content.encode('utf8'))
    f.close()

    commands.addremove(ui, repo)
    commands.commit(ui, repo, message=comment, user=rev['user'].encode('utf8'), date=timestamp)
