The code formatting doesn't work at all

[VorpalBlade]

Problem

When I try to format a file absolutely nothing happens. There is no error message, but the code is not changed either. I have looked in the Output window, the Debug Console etc and there is nothing there. I'm not sure how to proceed in debugging this issue further.

With regards to VSC-Prolog settings, the dialect is set to swi and the executable path is set to /usr/bin/swipl (which is indeed the correct path). Prolog linting seems to work properly, just not the formatting.

I pulled out the formatter_swi.pl and ran it myself on swipl:

removing the set_setting s makes it work.
