This D2 program tries to sort in-place a dynamic array of Foo according to
just
the first int x field (the third sort works on the whole structs), but when T
is a char the program doesn't compile:
import std.algorithm: sort, schwartzSort;
alias char T; // doesn't work
//alias int T; // works
struct Foo {
int x;
T[10] a;
}
void main() {
auto array = new Foo[10];
sort!(a.x b.x)(array);
static bool myComp(Foo f1, Foo f2) { return f1.x f2.x; }
sort!(myComp)(array);
sort(array);
}
Tested in DMD 2.064.2 and I'm unable to reproduce the bug. The final line fails
to compile because Foo doesn't define opCmp, but everything else is fine. The
default predicate for sort is a b and comparing two structs using less-than
requires defining opCmp.
Unless somebody else can reproduce this issue, I think we can close this bug
report.

(but doesn't run as I
expected, though), due to this :
import std.stdio;
struct Foo {
int x;
this(int x){this.x = x;}
}
void main() {
auto array = new Foo[10];
//for(int i = array.length; i 1; i--) { array[i].x = i; }
auto i = array.length;
foreach(Foo f; array) { f.x = --i; write(f.x);}
writeln();
foreach(Foo f; array) { write(f.x);}
}
giving that:

Never mind this part of the message, it's wrong code.
