Task #3
Bot24 Task
Renames Mexican TV station callsign redirects.
Operator(s)	Negative24
Script	rename_redirect.py
Script Author	Negative24
Type	Supervised (manual start; one-off batches)
Programming language(s)	Pywikibot

Description

Script renames a batch of redirects specified in a Python file with tuples corresponding to original (currently existing) redirects and new redirects. Script then makes sure the new redirect points to the target the old redirect pointed to. It then finds all references to the old redirect, finds the links, and then if the link points to the old redirect, it modifies the link to point to the new redirect, keeping the original section, label, and any other arguments (it only targets the title to begin with).

Operation Actions

FOR every old redirect in list of old redirects to new redirects:
1. IF old redirect doesn't exist, BREAK to next old redirect
2. IF new redirect doesn't exist, create it and point to final destination
3. Create a list of pages linking to old redirect to process; FOR every page in list of pages to process:
  1. FOR every link on page:
    1. IF link points to old redirect, modify the title to point to the new redirect

Consensus

Support

Support I commissioned this as a bot to simplify one of the most daunting tasks I've faced in my 10 years as an editor: the need to move hundreds of redirects as Mexico's analog-digital transition hits peak form. Since I began editing Mexico TV articles on a large scale in 2014, Mexico's digital transition has advanced extremely rapidly, which last year led to the beginning of the rewrite of the 32 state lists, and this year to many additions of new digital television technical information. I had to spend time doing the small batches of stations that were done earlier this year. It was quite a task just to do 10 or 12 of them, let alone the hundreds that will be changing over in the next month. With the DTV transition and analog shutoff occurring primarily this month, the use of a bot to complete the task will automate a lot of manual labor (hundreds of TV stations are affected, most of them redirects in Wikipedia) and ensure that my time can go to updating the separate articles that exist and improving coverage of Mexican broadcasting on en.wiki.

Objectives:

Demonstrate scripts capability to modify a new redirect correctly
Demonstrate scripts capability to change links from old redirect to new redirect correctly
Demonstrate scripts capability to work on pages with special characters

Scenario

The old redirect, testwiki:Ausdrücklich, has been created and pointed to testwiki:Robert Domes (diff). Many pages have been modified to contain different types of links (some with sections, labels, and linktrails) to the old redirect; some of these pages have special characters in their text and titles (diff 1 2 3).

Action

The old redirect will be renamed to testwiki:Äußerung.

Run

Command:

python scripts/rename_redirect.py -family:test -lang:test -redirectfile:../test1.py -summary:"Bot24 Task #3, Test #1: Bot Action! Renaming redirect"

Contents of test1.py:
