hey, right now i'm using a function like this
to set a dynamic array's properties

int[] array; set3array(array,1,2,3);

void set3array(inout ALfloat[] array, float x, float y, float z)
{
array.length = 3;
array[0] = x;
array[1] = y;
array[2] = z;
}

is there a better way to set array values than this?

array ~= x;
array ~= y;
array ~= z;

?

C

it is just so much nicer to be able to set the contents of an array in one line.

I like the C way: array[] = {1,2,3};

is there a good reason why D doesn't have this?

No idea.. it works for char[] eg.

char[] foo = "regan was here";
foo = "bob was here";

probably due to "regan was here" being converted to a char[] implicitly.


This also works...

ubyte[] b;
b = cast(ubyte[])x"010203";

(sets b[0] to 1, b[1] to 2, and b[2] to 3)
but is probably dependant on the endian-ness of the system it is compiled on?


I tried to get one like the above working for float, but could not seem to.

To answer this... Yes and No, it's because it's tricky and Walter has not yet implemented it.

I believe this is called an "Array literal", your example above is un-ambiguous, but, there are several which are. See the other posts in this NG about array literals.

Hopefully D will have this one day.

Although I haven't heard anything from Walter, I think this is just one of those things on his todo list.  The D form would be:

int array[] = [1,2,3]; 

Note that you can already do:

const int array [] = [1,4,5];

Or

	static int array[] = [1, 4, 5];

But yes, as said before, it ought to work generally.

But this isn't good when you don't want a const array.
I often wanted to write
int[] array = [1,2,x2-x1,y2-y1];

Especially useful it would be for multidimensional arrays.

I suppose "generally" would include this just as well.
