Tutorial on extension writing?

I would like to add some mathematical functions to calc and thought I would do them as a small extension. While I can download the SDK, the learning curve is steep simply because I can’t figure out what parts of the samples I need versus what parts are just there to provide a complete example.

Is there an extension writers guide someplace?


the best link for this is still http://wiki.services.openoffice.org/wiki/Extensions_development. It should contain the general concepts for extension authors and the SDK and our api page should contain the interface documentation.

A good start would be this Tutorial: Create a Hello World extension in LibreOffice
