Hello, I've just install VS code on windows to program in Ocaml but i can't run. The debugger doesn't seem to work...
I found this in a comment but i don't understand even when reading this https://marketplace.visualstudio.com/items?itemName=hackwaly.ocaml .

Please, can someone help me ?
Thank you in advance,

Hi. I would like to ask about the possibility to run the ocaml.
Is this a only way to run in the debugger model?
Is it possible to run like what we do in other ide?

I can't use the OCaml debugger either, can you be more precise on how to make it work ? I am using it on Windows, with OCaml installed through Cygwin.
When I run the debugger after compiling my .ml file with ocamlc -g, it prints out two Syntax errors and doesn't stop at breakpoints, simply executing everything.
