Make prompt more useful on Windows

Thanks very much. Could you perhaps provide a little bit more explanation about this? i.e., what is happening and the moment and what would make it more useful? I will try to get things going on a Windows machine at some point, but I don't have full access to one usually.

Oh, sorry. I made the pr during class and forgot to leave a description. The issue is that (when reading from stdin) the advice given says to "confirm input with enter+ctrl-d", but when running on windows the correct advice is actually to use enter+ctrl-z. I was considering checking what os the user was running on to give the correct advice but I thought giving the compiler input from stdin was probably a rare enough occurrence that it wasn't worth complicating the module for such a small change.

Sorry I didn't realise this wasn't merged, but actually the compiler has moved to a new project:
https://github.com/granule-project/granule-compiler-llvm/commits/master
Is there any chance you could make the change there.
That said, this problem also affects the interpreter in file interpreter/src/Language/Granule/Interpreter.hs which has a similar message which should be updated I think. So I think we should update that as well.

Now, all in all, I am starting to wonder how much we need this feature of reading from stdin. What do you think @buggymcbugfix ?

[buggymcbugfix]

We can take input from stdin because this allows us to pipe input from other programs, e.g.

echo "data Foo = Bar" | gr

I think I did this to allow for preprocessors, etc. but I don't think we're actively using this feature at the moment. Still nice to have imo.
