have you ever had a function in C: doSomething(a, b, c); and you want to see what it's printing out? this wraps that function so the output looks like this: doSomething(a,b,c): 37 c for it looks like printf("doSomething(a,b,c): \"%s\" ", doSomething(a,b,c)); :let @a = "0f(byt;iprintf("^[pa: "~@kb\"%s\" ", ^[$i)^[?%^Ml^]"
