sink is obsolete now, use W(riter)
```D
import std.range : isOutputRange;
void toString(W)(ref W writer) const
if (isOutputRange!(W, char))
{
// your stuff
}
```
writer can be @safe, @nogc, nothrow etc like you want
Thank you, and formatValue?

What you're basically asking for the first one is to convert
for row major to column major. There doesn't seem to be a
specific function for that, but you can piece it together. The
second one is just applying allReversed to the result of that.
So we have:
```d
/+dub.sdl:
dependency "mir-algorithm" version="~>3.10.25"
+/
import std.stdio: writeln;
import mir.ndslice.topology: iota, flattened, reshape,
universal;
import mir.ndslice.dynamic: transposed, allReversed;
void main() {
auto x = iota(2, 5, 3);
int err;
auto y = x.flattened.reshape([3, 5, 2], err).transposed!(1,
2);
auto z = y.allReversed;
writeln(x);
writeln(y);
writeln(z);
}
```
First of all thanks for your guidance and i modified your example
to get the results I was looking for.
auto y2 = base.flattened.reshape([3, 5, 2], err).transposed!(1,
2);
produced the following.
-
|0 10 20|
|1 11 21|
-
|2 12 22|
|3 13 23|

|4 14 24|

and auto y2 = base.flattened.reshape([3, 2, 5],
err).transposed!(1, 2);
gave me the result i was looking for.

When I compile the code above normal to an a.out binary it runs

What do I wrong?
gdc just compiles the program to a.out. It doesn't run the
resulting executable. You need to use something like rdmd
instead
of gdc. rdmd compiles to some temporary location and then runs
the executable.
Wow, that was fast. Thanks a lot!
