After a recent feature request I decided to look into adding category support for my Ulysses-Post-to-WP script. In the end it was actually easy. It involved changing one variable from
category. The hard part was finding out that was the needed change. The documentation isn’t very clear, and I had to pull a post out via XML-RPC to see the format. The testing and writing up the changes took more time than the actual change.
But now for people that prefer to use categories, it’s possible.
