Oh, oops, didn't notice it was in a class.
template Atoi(string s)
{
static if(s.length == 1)
enum int Atoi = s[0] - '0';
else
enum int Atoi = 10 * Atoi!(s[0 .. $ - 1]) + (s[0] - '0');
}
template parseRevision(string s)
{
// I'm assuming it'll always be of the form "\$ Rev: (\d+) \$"
enum parseRevision = Atoi!(s["$ Rev: ".length .. $ - 2]);
}
class A
{
immutable(int) x = parseRevision!("$ Rev: 182 $");
}
