gedaiu:
What i want to create, is an array structure like the one from
PHP where array levels are not fixed and the sintax to access
rhe values is val[][] so returning a reference to a struct that
have the same type as the current type is useful.
there is a way to do this in D?
Instead of returning float as in my case, you return something
else that has opIndex and opIndexAssign. This way you can pile up
the []:
import std.stdio;
struct Foo {
ref Foo opIndex(in size_t i) {
writeln("opIndex: ", i);
return this;
}
void opIndexAssign(in float value, in size_t i) {
writeln("opIndexAssign: ", value, " ", i);
}
}
void main() {
Foo f;
f[1] = 2;
f[3][4] = 5;
f[6][7][8] = 9;
}
That outputs:
opIndexAssign: 2 1
opIndex: 3
opIndexAssign: 5 4
opIndex: 6
opIndex: 7
opIndexAssign: 9 8
