Source code for scripts.cosmetic_changes

#!/usr/bin/env python3
"""This module can do slight modifications to tidy a wiki page's source code.

The changes are not supposed to change the look of the rendered wiki page.

The following parameters are supported:

-always           Don't prompt you for each replacement. Warning (see below)
                  has not to be confirmed. ATTENTION: Use this with care!

-async            Put page on queue to be saved to wiki asynchronously.

-summary:XYZ      Set the summary message text for the edit to XYZ, bypassing
                  the predefined message texts with original and replacements
                  inserted.

-ignore:          Ignores if an error occurred and either skips the page or
                  only that method. It can be set to:
                  all - does not ignore errors
                  match - ignores ISBN related errors (default)
                  method - ignores fixing method errors
                  page - ignores page related errors


The following generators and filters are supported:

&params;

&warning;
