Imports incorrectly part of "allMembers" trait output?
When compiling the following code with DMD 2.072.2:
class LeClass {
import std.stdio;
}
void main() {
foreach (memberName; __traits(allMembers, LeClass)) {
pragma(msg, memberName);
}
}
The following output is shown in the console:
std
toString
toHash
opCmp
opEquals
Monitor
factory
Note how "std" is part of the output of allMembers. Is this a bug
or is this intended behavior? I don't think imports are
necessarily members of a class. It also happens for static
imports.
[Vibe.d] Handling event loop manually
In my application I have already have an event loop running taking care of all sorts of things. Now I want to use Vibe.d to run an asynchronous websocket API to provide some debugging information. Normally Vibe.d's main takes care of handling the event loop. I want to run vibe's event loop manually. So far I tried to get the EventDriver and calling processEvents() but this does not seem to service any connections at all. runEventLoop() and runEventLoopOnce() do process the connections but of course block the whole event loop. Does anyone know how I can do this?
Implicit casting of int enum members to int
Consider the following code:
enum StringTypeEnumOne : string {
bla = "bla"
}
enum StringTypeEnumTwo : string {
bleh = "bleh"
}
enum IntTypeEnumOne : int {
bla = 1
}
enum IntTypeEnumTwo : int {
bleh = 2
}
public void main() {
string[] strings = [StringTypeEnumOne.bla,
StringTypeEnumTwo.bleh];
int[] ints = [IntTypeEnumOne.bla, IntTypeEnumTwo.bleh];
}
When compiled the following compilation error is thrown:
src\app.d(19,16): Error: cannot implicitly convert expression
(cast(IntTypeEnumOne)1) of type IntTypeEnumOne to IntTypeEnumTwo
The string members are implicitly cast just fine, however I also
expected the members of the int enum to be cast implicitly
because I explicitly defined the base type of the enum.
Is this a bug in D? Or is using an int as base type the same as
having no base type at all?
