The Pywikibot framework is a Python library and collection of scripts to automate work on MediaWiki sites.

Prerequisites

To effectively use Pywikibot on Toolforge, you need:

Installation and setup

  1. Become your tool-account
    MAINTAINER@tools-sgebastion-10:~$ become TOOLNAME
    
  2. Create a setup script (e.g., pwb_venv.sh) that creates a virtual environment and installs dependencies.
    tools.TOOLNAME@tools-sgebastion-10:~$ touch $HOME/pwb_venv.sh
    tools.TOOLNAME@tools-sgebastion-10:~$ chmod ug+x $HOME/pwb_venv.sh  # make the script executable
    
    You need to install from git if you want to use the Pywikibot scripts.
Pywikibot installation source Example
PyPI
pwb_venv.sh
#!/bin/bash

# clean-up directories if they already exist
rm -fdr pwbvenv

# create a virtual environment
python3 -m venv pwbvenv

# activate it
source pwbvenv/bin/activate

# install dependencies
pip install --upgrade pip setuptools wheel
pip install pywikibot[mwoauth,mysql]  # update as needed
pip install ... # any other dependencies here
git
pwb_venv.sh
#!/bin/bash

# clean-up directories if they already exist
rm -fdr pwbvenv $HOME/pywikibot-core

# create a virtual environment
python3 -m venv pwbvenv

# activate it
source pwbvenv/bin/activate

# clone Pywikibot
git clone --recursive --branch stable "https://gerrit.wikimedia.org/r/pywikibot/core" $HOME/pywikibot-core

# install dependencies
pip install --upgrade pip setuptools wheel
pip install $HOME/pywikibot-core[mwoauth,mysql]  # update as needed
pip install ... # any other dependencies here
  1. Run the setup script using the jobs framework.
    tools.TOOLNAME@tools-sgebastion-10:~$ toolforge-jobs run setup-venv --command $HOME/pwb_venv.sh --image python3.11 --wait
    INFO: job 'setup-venv' completed
    
  2. Configure Pywikibot
    • Interactively:
      tools.TOOLNAME@tools-sgebastion-10:~$ webservice python3.11 shell  # start an interactive Kubernetes shell
      tools.TOOLNAME@shell-#########:~$ source pwbvenv/bin/activate  # activate the virtual environment
      (pwbvenv) tools.TOOLNAME@shell-#########:~$ pwb generate_user_files  # run the generate_user_files.py Pywikibot script
      
      user-config.py and (optionally) user-password.py are generated by following the prompts.
    • Manually: See the manual on MediaWiki wiki: user-config.py, BotPasswords, and OAuth.
  3. You may test the installation from an interactive shell.
    tools.TOOLNAME@tools-sgebastion-10:~$ webservice python3.11 shell  # start an interactive Kubernetes shell
    tools.TOOLNAME@shell-#########:~$ source pwbvenv/bin/activate  # activate the virtual environment
    (pwbvenv) tools.TOOLNAME@shell-#########:~$ pwb version  # run the version.py Pywikibot script

Create jobs

Main article: Help:Toolforge/Jobs framework

Example of running the Pywikibot version.py script once:

tools.TOOLNAME@tools-sgebastion-10:~$ toolforge-jobs run pywikibot-version --command "$HOME/pwbvenv/bin/pwb version" --image python3.11

Example of running your own script on a schedule:

tools.TOOLNAME@tools-sgebastion-10:~$ toolforge-jobs run my-cool-job --command "$HOME/pwbvenv/bin/python3 $HOME/my-cool-script.py" --image python3.11 --schedule "1 2 * * 3"

Additional parameters for the job could include, for example, additional memory allocation (--mem MEM), job restart after being finished (--continuous), etc.

OAuth

Pywikibot can use OAuth v1.0a as the method of authenticating with wikis. To configure this behavior for Wikimedia wikis, follow the instructions in Manual:Pywikibot/OAuth/Wikimedia.

Warning Caution: When using OAuth as the authentication method, be sure to set the correct permissions on the user-config.py file as described in Manual:Pywikibot/OAuth. This will keep your OAuth credentials more secure.

To learn more about OAuth in general, see OAuth/For Developers.

Next steps

Now that you know how to run your bot on Toolforge, read the script development and maintenance tips described in Help:Toolforge/Developing successful tools. These tips will help you to license, publish, and support your bot over time.

If you are looking for ideas on what types of scripts you can run using Pywikibot, see Manual:Pywikibot/Scripts. If you want to write your own script, see Manual:Pywikibot/Cookbook.
