Yes, that's how I am doing it. FYI I took your example config at the bottom of the [LSP](https://forum.nim-lang.org/postActivity.xml#LSP) page [1] and changed `${file_basename}` to `${file_base_name}` because `${file_basename}` does not exist. When I try lauch debugging on a test program `pre_debug_task` runs and never completes. If I compile manually and launch debugging with `pre_debug_task` commented out it also hangs there until I press the stop button. I do not see any related output at all in the ST4 console. Thank you! [1] FYI right now markup is failing to format that JSON snippet correctly.
