That’s good to know. Once we decide to stabilize our profiling and debugging features and make them public, we’ll have a closer look into the tracing API of Saxon.
Thanks Christian
PS: Our team member Sabine extended our Wiki article on the integration of IntelliJ. She might soon give you some feedback on her experiences with BaseX and your plugin.

Hi Reece,
I'm wondering how you would go about profiling a query in BaseX to
determine how long various query statements take, so you can look at the places where you need to modify the query to be faster. I have added MarkLogic's profiling support into my XQuery plugin that does this and am wondering how this can be done in BaseX.
Have you already embedded support for the Saxon debugger in IntelliJ?
The current development version of my plugin adds support for the Saxon tracing API and am using that to generate a profile report similar to the one for MarkLogic. This is working well. I am still investigating debugging support for both Saxon and MarkLogic.
A similar tracing API could be useful for BaseX. Specifically, the ability to add trace objects into the evaluation pipeline that call events on a listener class before and after evaluation. I could make use of that API in my plugin to provide profiling and debugging functionality.
I'm still planning on using the timing information and query plan from BaseX.
Kind regards, Reece
