Check the Schedule for an overview of all talks during this conference.

Meta-programming means creating program code from meta descriptions rather than directly coding in a classic programming language. It is used to overcome limitations of a programming language, to automize creation of repetitive code or to avoid the need to maintain the same information at different locations in different formats.

KDE uses the technique of meta-programming at various places. It is one central concept behind the latest generation of the KDE configuration framework, KConfig XT, where the C++ code for accessing configuration options is automatically generated from meta descriptions provided in XML format. That significantly simplifies application code making use of configuration options and provides new opportunities to take profit of the fact that configuration options are accessible in a standardized and well-defined way.

This talk will give an overview of the various flavors of meta-programming used in KDE, focus in detail on how this concept is used in KConfig XT and give some ideas where it could be applied in the future.
