Nice article!
There, I found an interesting way of writing ranges that are not
explicitly initialized:
private import core.stdc.stdio;
struct StdinByChar {
@property bool empty() {
if (hasChar)
return false;
auto c = fgetc(stdin);
if (c == EOF)
return true;
ch = cast(char)c;
hasChar = true;
return false;
}
@property char front() {
return ch;
}
void popFront() {
hasChar = false;
}
private:
char ch;
bool hasChar;
}
This is unusual to me that popFront() code is shifted to empty(), but I
guess that's necessary because structs doesn't have () ctors.
