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 ?
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);
}
---
And oh, maybe this is not the right place for a beginner ? Is
there any better place ?
The D.learn group is the most appropriate for these kinds of
questions :)
