Just put it in a separate module and then import it. e.g.
file: mypackage/constants.d
==================
module mypackage.constants;
GLfloat[] vertices =
[
// Positions // Texture Coords
-0.5f, -0.5f, -0.5f, 0.0f, 0.0f,
0.5f, -0.5f, -0.5f, 1.0f, 0.0f,
.....
(lots and lots of values)
.....
];
==================
file: main.d
==================
import mypackage.constants;
void main()
{
auto v = vertices;
}
==================
Probably the key thing to remember is that when you compile your program,
all of the modules that are part of your program rather than a separate
library need to be compiled into it. Simply importing them isn't enough -
though using either rdmd or dub make that easier.
This is the official documentation's page on modules:
http://dlang.org/spec/module.html
This is the chapter from Al's book that covers modules:
http://ddili.org/ders/d.en/modules.html
And you'd almost certainly benefit from simply reading Ali's book as a
whole:
