A Cookiecutter template for MediaWiki extensions.


  • Comes with all features of the upstream BoilerPlate extension (only english i18n, see i18n/
  • Makefile support (make help, make install, make update, make test)

Features (future)

  • License support
  • Tests using PHPUnit

Optional Integrations

These features can be enabled during initial project setup.

  • Set the extension type
  • Add an example special page [[Special:HelloWorld]]
  • Add an example parser hook {{#something: }}
  • Integration with Gerrit (using git-review)


  • Cannot create MediaWiki skins. See cookiecutter-mediawiki-skin for that. (In theory, you can select the skin option, but it doesent do anything special for skins right now. A separate repository is better imho.)


Let's pretend you want to create a MediaWiki extension called "SomeExtension". Rather than cloning the BoilerPlate extension, and then changing every occurrence of BoilerPlate by hand, use cookiecutter to do all the work.

First, get cookiecutter. Trust me, it's awesome:

$ pip install cookiecutter

Now run it against this repo:

$ cookiecutter

You'll be prompted for some questions, answer them, then it will create a custom MediaWiki extension for you.

Note: If you want to conform with all naming conventions (PHP, JS/CSS, Composer) you should watch closely when filling out the project template parameters. The default values are conforming with all conventions.

It prompts you for questions. Answer them:

Enter the project and take a look around:

$ cd SomeExtension/
$ ls

Create a GitHub repo and push it there:

$ git init
$ git add .
$ git commit -m "Initial commit: MediaWiki extension SomeExtension"
$ git remote add origin
$ git push -u origin master

Now take a look at your repo. Don't forget to carefully look at the generated Awesome, right?
