Clang and wasm about a-shell

[ifuchs]

I am playing around with clang and wasm, using some c tutorial files and I cannot get scanf to work. Is this a limitation of the implementation? What am I missing? Here is the test file:

`#include <stdio.h>

int main () {
char str1[20], str2[30];
printf("Enter name: ");
scanf("%s", str1);
printf("Enter your website name: ");
scanf("%s", str2);
printf("Entered Name: %s\n", str1);
printf("Entered Website:%s", str2);
return(0);
}

Yes, this is known limitation. For the time being, wasm listens to stdin if it is redirected, but not if it comes from the keyboard. So echo name website_name > wasm a.out will work, but not what you tried. I'll keep that in mind as a possible use.

Having a way to get input for C and C++ programs would certainly make it more useful.

That will probably come with the ability to open files (also something really useful).

Now that you’ve added the file capability, perhaps you can also add input from stdin?
