Hello, I have an idea about a small code tool related to the
application resources.
It would rely on the assumption that some global variabled,
sharing the same type and attributes, declared in group, are
contiguous.
In short I need to know if the following assertions are always
true and reliable over time:
--------------
import std.stdio;
// used as base adress
static string beg = "";
// arbitrary generated by a tool and mixed at compile time.
static string a = "";
static string b = "";
static string c = "";
static string d = "";
static string e = "";
static string f = "";
void main(string args[])
{
void* offs = &beg;
assert( &a == (offs + (size_t.sizeof * 2) * 1) ); // length +
ptr
assert( &b == (offs + (size_t.sizeof * 2) * 2) ); // length +
ptr
assert( &c == (offs + (size_t.sizeof * 2) * 3) ); // etc.
assert( &d == (offs + (size_t.sizeof * 2) * 4) );
}
--------------
In a second time I need to be sure that the return tuple of the
trait "allMembers" follow the declarations order. The
documentation says that:
"The order in which the strings appear in the result is not
defined".
But so far, it looks like it's ordered according to the
declaration (at least for a module containing only some global
variables).
Any other remarks about the topic are welcome.
