Hello Ben,
Hi there,
Can anyone tell me how to get the maximum char value from a string
type? I have a template struct which can take string or wstring and
need to determine the character type from the string type.
If you are looking for the X sutch that the following is true (as long as
fn returns a valid string)
someStringType foo = fn();
assert(foo[rand()%$] <= X); // check a random position.
Bits out of the following should work:
template Max(T) {
static if(is(T U : U[]))
const string Max = U.stringof ~ ":" ~ (cast(int)(U.max)).stringof;
else static assert(false, "oops");
}
import std.stdio;
void main()
{
writef("%s\n", Max!(string));
writef("%s\n", Max!(wchar[]));
writef("%s\n", Max!(dchar[]));
}
Output:
char:cast(int)'\xff'
wchar:cast(int)'\U0000ffff'
dchar:cast(int)'\U0010ffff'
Thanks,
Ben
