So you want to become an OmegaWiki developer ...
You will need a reasonable understanding of PHP & MySQL web development, and version control with Git.
Setting up your environment
- Install Apache
- Install PHP 5.2.3+ with MySQL support/extension (don't forget to modify php.ini to activate the extension). Watch out: Some distributions are still using 5.1. Be sure to check! You can use this handy script: phpinfo.
- if you have "php5-suhosin" installed, you'll need to remove it since it breaks some functionalities of OmegaWiki because it limits the amount of information sent by POST, or something like that.
- Install MySQL 5+
- Configure MySQL to use UTF-8:
- Edit your my.cnf configuration file
[mysqld], add the following lines:
[mysql], add the following:
- Restart MySQL. When you run the "status" command in the MySQL client, all "characterset" settings should be set to "utf8" like this:
Server characterset: utf8
Db characterset: utf8
Client characterset: utf8
Conn. characterset: utf8
- Install Git
Under the Ubuntu as well as under the debian GNU/linux operating systems, the following commands should install all the necessary packages:
sudo apt-get install apache2 libapache2-mod-auth-mysql libapache2-mod-php5 php5 php5-intl php5-mysql mysql-client mysql-server git git-review
Installing MediaWiki and WikiLexicalData
There are two options:
- Installing from scratch
- Installing with an existing database (such as the OmegaWiki database)
Understanding the code

Documentation can use improvement. Help is especially needed in this department! Contact Erik (erik AT wikimedia DOT org) and he'll give you a whirlwind tour through the main things you understand.
A good place to start is the general MediaWiki documentation.
Our documentation can be found at http://doc.omegawiki.org. Note that lots of classes and functions have not yet been commented.
