I want a module level initialised delegate. if I try
module foo;
enum Status
{
success,
}
class StatusException : Exception
{
Status s;
// usual exception constructors
}
void delegate(Status) onError = (Status s) { throw new
StatusException(s);};
I get a error like cannot initialise something that needs a
context at compile time. Ignoring the fact the the initialiser
does not need a context, if I do
void delegate(Status) onError;
static this()
{
onError = (Status s) { throw new StatusException(s);};
}
void main()
{
import std.stdio;
writeln(onError.funcptr); // null
}
WAT?
void delegate(Status) onError;
static this()
{
import core.stdc.stdio;
printf("initialising onError");
onError = (Status s) { throw new StatusException(s);};
printf("initialising onError: funcptr = 0x%x",
onError.funcptr);
}
void main()
{
import std.stdio;
writeln(onError.funcptr);
}
output:
null
No "initialising onError", the static this is not even being run!
I'm using LDC master.
