[Question] Missing GetStr?

[Nedihardt97]

I've been playing around with your compiler using it to rewrite a program for modifying files that I had in another language and I've seem to have hit a roadblock with reading in a user input.
From what I'm aware of, TempleOS uses GetStr and GetI64, but the compiler does not recognize these functions. Are cin like functions simply missing from the definitions or are they under a different alias?

Btw, really been enjoying messing around with this compiler, solid work!

Hey I'll give you two answers here.

The shallow answer is that I've not implemented it, you can see a list of functions available in the documentation here;

In-depth answer is that GetStr relies on the TempleOS operating system it uses a global fp_getstr2 function pointer initilised to SysGetStr2(...) which calls GetS(...) -> GetChar(...) -> GetKey(...) -> ScanKey(...) -> ScanMsg(...) which relies on "tasks" which are TempleOS processes. Which means we can't really implement it via copy paste. If you want to follow that it starts here;

I think something like the following could work but I'm in no rush to hurry it;

extern "c" U8 getchar();

U8 *GetStr(U8 *msg=NULL, U8 *dft=NULL, I64 flags=0)
{
  if (msg) "%s", msg;
  U8 buffer[1024];
  I64 idx = 0;
  while ((ch = getchar()) != EOF) {
    if (ch != /* some sort of terminator */) {
      buffer[idx++] = ch;
    } else {
      break;
      }
  }
  buffer[idx] = '\0';
  return StrNew(buffer);
}
