Hi,

Ok basically I have a big static array, into which I want 4 static slices.

I thought this would work...

static char[6] a = "abcdef";
static char[3] p = a[0..3];
static char[3] q = a[3..6];

but, the slices are char[] and you cannot assign a char[] to a char[3] (even if they are the same length). So I tried...

static char[6] a = "abcdef";
static char[3] p = cast(char[3])a[0..3];
static char[3] q = cast(char[3])a[3..6];

and now it does not like it because cast(char[3])a[0..3] is a non constant expression.

So, is there any way to define a bunch of static slices into a static array?


I did get this to compile...

static char[6] a = "abcdef";
char[3] p;
char[3] q;

static this() {
	p[] = a[0..3];
	q[] = a[3..6];
}

int main(char[][] args) {
	return 0;
}

but, I am not 100% certain I know what it's doing exactly? is it copying? or just taking a static slice...

Regan.

Do this:

It doesn't work "non-constant expression a[0..3]".

Whoops. I meant:

static char[6] a = "abcdef";
char[] p = a[0..3];
char[] q = a[3..6];

Same error. Are you trying these? I have tried a number of things, just like these you are suggesting...

Hey, that one worked for me! Look, see - here's my source code:

It compiles for me. I'm using the latest compiler, too.

My appologies, I need the static array to me at module level, my code reads:

static char[6] a = "abcdef";
char[] p = a[0..3];
char[] q = a[3..6];

int main(char[][] args) {
	return 0;
}

I don't know is this what you want but:

static char[6] a = "abcdef";
char[] p;
char[] q;

static this()
{
     p = a[0..3];
    q = a[3..6];
}

int main(char[][] args)
{
return 0;
}
