It’s been ages since I first thought I should publish a quick reference sheet for Dokeos developers. It’s now done. It’s a first version but I think it will be really useful to new Dokeos developers. It is already useful for me (particularly for $httpHeadXtra and $htmlHeadXtra), so I don’t doubt that bit.
It is published under the Creative Commons BY-SA license (Paternity, Share-Alike) and I have the SVG format locally, so just ask me for it if you want to extend it. I might pretty well extend this sheet to specific class methods (like Database and Security) in the near future, but this is a good start.
