This is two bugs at once. The first is a regression in 2.048 from 2.047 where
splitlines is no longer CTFEable. The second is that, in 2.047, splitlines
doesn't work when CTFE'd.
// 2.048
void main()
{
static auto s = splitlines("a\nb"); // Error: not CTFEable
writeln(s[0]);
}
// 2.047
void main()
{
auto s = splitlines("a\nb"); // Note non-static
writeln(s[0]); // Writes 'a'... correct!
}
// 2.047
void main()
{
static auto s = splitlines("a\nb"); // CTFE'd this time
writeln(s[0]); // Writes nothing... incorrect!
}
Note that the 2.048 was run on Windows 7 and the 2.047 was run on Mac OS X Snow
Leopard.
Also note that string.split appears to have the same issue (was CTFEable in
2.047, but not in 2.048).
