How to become a BlueSpice hacker

This article is written to help novice developers learn the skills needed to contribute to BlueSpice development.

Why should you contribute?
When you are actively involved in a project you get the opportunity to shape its future. Changes are caused by actions. You will certainly receive a big "thank you" and you will be publicly credited related to your work. Even more, you are helping a lot of users who will thank you quietly or loudly.

Join in[edit | edit source]

Like in every other project there are lots of possibilities to participate. Here a few examples of what you could do in the BlueSpice project.

Improving the code quality[edit | edit source]

  • Doc blocs: Write with us documenting blocs in the source code. This helps us to complete the code and check for discrepancies. More about the MediaWiki DocBlocks at wikimedia.
  • Coding conventions: Help to enforce coding conventions. We use the Coding Conventions of MediaWiki.
  • Security: has high priority. Please help to improve it. Therefore you should have a look at Security for developers.

Bugfixes[edit | edit source]

Look for minor and major bugs. And if you already programmed the solution, well, all the better!
Here you can find some help on debugging in MediaWiki

Code Review[edit | edit source]

Help us to review code contributions. Therefore you have to be familiar with gerrit. Find more information at "setting up a development environment" und "committing changes".

Small addition[edit | edit source]

A lot of the existing extensions want to be developed and provide opportunities to extend the functionality. What we have in mind:
Dashboard Widgets, Statics, Sidebar, Widgets, etc.

Own extensions[edit | edit source]

Of course you can develop your own BlueSpice extensions. Please follow the MediaWiki workflow. You will find a good tutorial on MediaWiki pages like this one MediaWiki developing extensions MediaWiki. These notes should also be consulted for developing BlueSpice. Please create a separate repository in gerrit that is named like this:


Translations[edit | edit source]

Translations are needed all the time. Please contact the community of

This is how it works[edit | edit source]

Commit changes[edit | edit source]

There are two possibilities to supply patches.

1. Mail to Hallo Welt!

Send an e-mail with your patch in (git format-patch) to We will commit the change for you in git where it has to go through a standardized process.

2. Actively participating via Git

We follow the procedure that is also common in the MediaWiki developer community:

  • Get a developer account for MediaWiki
  • Install git-review
  • check out the BlueSpice code
  • Commit your changes
  • Changes are verified in gerrit
  • When everything is ok, your changes will be accepted

On you will find a short and a extended tutorial.

The BlueSpice code can be found in these repositories:


and this is how you check out:

git clone ssh:// 

In the repositories of BlueSpice it is necessary to have the "+2" or "Merge" permission before you can commit code to the product by yourself. Please ask Markus Glaser if you feel you need this kind of access (

If you want to write own extensions for BlueSpice please ask for an own repository here. Please follow the naming convention.
