Hi there,

So I've just stated learning D. Playing with associative arrays, 
I wrote this simple function. No big deal.

void associativeArrayFu(){
	ulong[string] arr;
	arr["foo"]=1;
	arr["bar"]=2;
	arr["foo"]=45;
	
	foreach( thing;arr.sort){
		writeln( thing );
		}
	}

Compiles and runs just fine.
Stating to have a bunch of funtions in one file, I reorganised my 
sources among several files (in the same project in Eclipse).

Now the same function yelds this error when compiling:

Error: no property 'sort' for type 'ulong[string]'

wether it is in a source file alongside other functions, alone in 
its own file, or even all alone in its own project.

Not that I care that much about this poor function, but I am 
puzzled. What did I miss ?

And oh, maybe this is not the right place for a beginner ? Is 
there any better place ?

Associative arrays are not sortable and have no defined order of 
element pairs. You can get an array of its values and sort that, 
by using the `values` property:

---
import std.algorithm : sort;
import std.stdio : writeln;

foreach(value; aa.values.sort())
{
     writeln(value);
}
---

The D.learn group is the most appropriate for these kinds of 
questions :)

Yep, that's definitely the point that I missed.

 that, by using the `values` property:
 ---
 import std.algorithm : sort;
 import std.stdio : writeln;

 foreach(value; aa.values.sort())
 {
     writeln(value);
 }

OK, I get the idea. I am still a bit removed from navigating the 
numerous libraries, but I'll guess I'll get used to it.

Yep, found out later that it was right in front of me, d'oh ;-)


thanks a lot for your spot-on answers !
