Other languages: is a Pywikibot script used to revert certain edits.

The script helps you clean up after your bot if it does undesirable things. It goes through your bot's list of contributions, from most recent to most ancient, and reverts the last revision your bot made on each page – provided, of course, that your bot made the most recent revision on the page.

It is therefore most effectively used immediately after you notice your bot has gone astray.


It is invoked by typing python revertbot.

It should almost certainly not be run unattended, as it does not ask for permission to make changes. Its default – and unalterable – mode is just to automatically make changes.

The following command line parameters are supported:

-username Edits of which user need to be reverted. Default is bot's username (site.username())
-rollback Rollback edits instead of reverting them. Note that in rollback, no diff would be shown
-limit:num Use the last num contributions to be checked for revert. The default is 500

Users who want to customize the behaviour should subclass the BaseRevertBot and override its callback method. Here is a sample:

class myRevertBot(BaseRevertBot):

    '''Example revert bot.'''

    def callback(self, item):
        '''Sample callback function for 'private' revert bot.

        @param item: an item from user contributions
        @type item: dict
        @rtype: bool
        if 'top' in item:
            page = pywikibot.Page(, item['title'])
            text = page.get(get_redirect=True)
            pattern = re.compile(r'\[\[.+?:.+?\..+?\]\]', re.UNICODE)
            return bool(
        return False

Global arguments available

These options will override the configuration in settings.

Global options
Parameter Description Config variable
-dir:PATH Read the bot's configuration data from directory given by PATH, instead of from the default directory.  
-lang:xx Set the language of the wiki you want to work on, overriding the configuration in xx should be the language code. mylang
-family:xyz Set the family of the wiki you want to work on, e.g. wikipedia, wiktionary, wikitravel, ... This will override the configuration in family
-user:xyz Log in as user 'xyz' instead of the default username. usernames
-daemonize:xyz Immediately return control to the terminal and redirect stdout and stderr to file xyz. (only use for bots that require no input from stdin).

-log:xyz Enable the log file, using 'xyz' as the filename. logfilename

-maxlag Sets a new maxlag parameter to a number of seconds. Defer bot edits during periods of database server lag. Default is set by maxlag
Set the minimum time (in seconds) the bot will wait between saving pages. put_throttle
Enable the log file and include extensive debugging data for component "item" (for all components if the second form is used). debug_log
Have the bot provide additional console output that may be useful in debugging. verbose_output
Toggles the cosmetic_changes setting made in or to its inverse and overrules it. All other settings and restrictions are untouched. cosmetic_changes
-simulate Disables writing to the server. Useful for testing and debugging of new code (if given, doesn't do any real changes, but only shows what would have been changed). simulate
-<config var>:n You may use all given numeric config variables as option and modify it with command line.
