Sets all the buttons to the flash color and after an timeout
removes the flash color from all the buttons.
Thanks for your answer,
but as i said before, i want to flash each button on it's own
(the game is kinda like 'Simon Says').

What's going on? The docs say that it creates a new process. I
simply want to clear the console!
I have problem with executeShell on windows 10 (LDC 1.0.0) too.
When I rewrote it into http://prntscr.com/blc9j8 it works.
OT but please, refrain from using screenshots. I know it's very
customary on windows but I can't copy paste code from a
screenshot to play with it and manually copying is error-prone.
We manipulate text, let's stay with it.

Unsolicited spelling correction: no 'i' in "deprecated".

`system` directly prints its output, `executeShell` returns it in a
tuple with the status code. Maybe cls works by printing some specific
clear code. If so, you have to print the output of the command.
This works with `clear` on Linux which seems to behave similarly to
Windows' cls:
void main()
{
import std.stdio: write, writeln;
import std.process: executeShell;
import std.exception: enforce;
writeln("A");
auto r = executeShell("clear");
enforce(r.status == 0);
write(r.output);
writeln("B");
}
`wait(spawnShell(...))` is the other suggestion from `system`'s
deprecation message. It works for `clear`, too:
void main()
{
import std.stdio: writeln;
import std.process: spawnShell, wait;
writeln("A");
wait(spawnShell("clear"));
writeln("B");
}
executeShell doesn't work but system does
system("cls") works but executeShell doesn't. system is
depreciated.

There seems to be a few problems here:
1. It seems like getOverloads is returning 0 for 'foo' - is
this a bug? Was expecting a 3 or at least a 2 if the template
would be ignored.
2. That alias breaks getProtection - is this bug? Seems like it
should be public.
These two make it quite hard to iterate over and collect info
about arbitrary aggregates.
I want to get a list of all *public* members, including
pointers to all public member functions and their overloads,
excluding template member functions. This is turning out to be
hard due to these "unexpected behaviors".
Is there anything else I can do?
__traits(getOverloads, x, Member).length works if you place the
template after a function of the overloads and then it returns 2.
it fails as soon as the first member of the overload set is any
template, so i guess it must be a bug.
e.g.
struct Fails
{
void foo()(){}
void foo(int){}
}
struct Works
{
void foo(int){}
void foo()(){}
}
__traits(getOverloads, Fails, "foo").length.writeln; // 0
__traits(getOverloads, Works, "foo").length.writeln; // 1

But i want to flash (e.g. change the CSS class) the buttons one by one

Okay, i tried it with a new private int-variable which contains the
current index of the for-loop, like this:
private void letButtonsFlash(){
foreach(Button btn;bArr){
btn.setSensitive(false);
}
for(int i = 0; i < level; i++){
index = i; //index is public
Button currentButton = bArr[rndButtonBlink[i]];
ListG list = currentButton.getStyleContext().listClasses();
string CSSClassName = to!string(cast(char*)list.next().data);
currentButton.getStyleContext().addClass(CSSClassName ~
"-flash");
Timeout t = new Timeout(&timeout_delay,1,false);
}
foreach(Button btn;bArr){
btn.setSensitive(true);
}
}
bool timeout_delay(){
Button currentButton = bArr[rndButtonBlink[index]];
ListG list = currentButton.getStyleContext().listClasses();
string CSSClassName = to!string(cast(char*)list.next().data);
currentButton.getStyleContext().removeClass(CSSClassName ~
"-flash");
return false;
}
But now the strange thing happens, that the first button lights up as
expected but the second button remains at its "flash color" and doesn't
go back to normal color, i don't understand why this happens? Any ideas?
You should probably increment the index in the timeout_delay function.

Overloads
Consider this snippet:
struct X {
int foo(Args...)(Args args) if (Args.length > 1) { return
Args.length; }
int foo() { return 0; }
int foo(int y) { return 1; }
alias Name = string;
int field_;
}
void listMembers(T)(ref T x) {
foreach (Member; __traits(derivedMembers, T)) {
pragma(msg, Member, " ", __traits(getOverloads, x,
Member).length);
//pragma(msg, __traits(getProtection, __traits(getMember, x,
Member))); // Error: argument string has no protection
}
}
void main() {
X x;
listMembers(x);
//auto fptr = &x.foo; // Error: x.foo(Args...)(Args args) if
(Args.length > 0) is not an lvalue
}
Output:
foo 0LU
Name 0LU
field_ 0LU
foo 0LU
Name 0LU
field_ 0LU
