While it seems you are using VSC-Prolog I have been using Prolog which seems to be less popular and has less features. I didn’t know there was another more popular extension as I have been using this one for more than a year.
For the most part it seems we are on our own on this one.
Truth be told, with Prolog I really don’t need or expect the heavy lifting of syntax refactoring, etc, that other IDEs have because with Prolog I rarely need anything more than my brain, a place to type in the code and a Prolog command line to run the code. The visual debugger is nice when needed for small code, but with a methodology of using test cases and brain power, really don’t need it much either.
Cheers,
Eric
