Thank you, that has been helpful, and I'm making some progress, but here I'm stuck again. As far as I can see, the program compiles to binary which I can start from console and it works correctly, but I don't see it running from VS Code interface: I was assuming I will get the output of the program somewhere down there in terminal because I used "Run withoud debugging" command.
All I get is: * Executing task in folder Nim: /snap/bin/nim-lang.nim c -d:debug --debuginfo --lineDir:on --debugger:native main.nim Hint: used config file '/snap/nim-lang/1589/config/nim.cfg' [Conf] Hint: used config file '/snap/nim-lang/1589/config/config.nims' [Conf] .... Hint: [Link] Hint: 22417 lines; 0.163s; 25.59MiB peakmem; Debug build; proj: /home/xxx/Nim/main.nim; out: /home/xxx/Nim/main [SuccessX] * Terminal will be reused by tasks, press any key to close it. Run How can I actually see the output of it in VS Code?
