In same module private acts like friend in C++.
Hi,
I have win32 program, which takes command line parameters and
passes them trough socket to another program, running on the same
machine. If connection fails, it needs to start the another
program.
I don't want console to popup so I added -L/SUBSYSTEM:WINDOWS.
This works fine, except

When iterating through class members using traits how do you
filter out the member vars to only get a list of methods. I think
i've solved it in the code below but it feels like i am abusing
MemberFunctionsTuple. Is this the correct way to do this?
private template Methods(T, int index = 0)
{
Key part here is is(T == function) - because of D type system
funny properties only possible way to get T that matches that
condition is to do `typeof` from declared function/method symbol.
That type can't be manually expressed and thus used for member
variable.
http://dpaste.dzfl.pl/c250e798
import std.traits, std.range;
private template Methods(T)
if (is(T == class))
{
private string[] getMethods()
{
string result[];
foreach (member_string; __traits(allMembers, T))
My guess, just looking at it, is that spawnProcess fails because
there's no streams available for stdin, stdout, and stderr. It
tries to reuse the ones of the parent process, but without a
console they don't work.
It might help to use Config.suppressConsole.. I'm just guessing
but maybe

You want to list private members or want them ignored
Thank you, Config.suppressConsole did not help, but redirecting
the std:s did.

Something along the lines of
static if(__traits(compiles, __traits(getMember, Foo, member))
static if(is(__traits(getMember, Foo, member) == function)) {
// use it
}
The __traits(compiles, ...) is my go-to thingy for filtering out
random errors.

Try using opDispatch as a described in the other thread.
I'll give that a go, but I still think this is a bug that needs fixing. The
example in TDPL p. 231 will very clearly also not work due to this issue.

Since D allows to call methods without parentheses.
No, not in typeof. It will try to call it with `member.stringof`
though, thus
Code:
import std.stdio;
void foo(short x, short y) { }
void foo(short[2] xy) { }
void main()
{
foo(1, 2); /// works
foo([1, 2]); /// works
ushort[2] xy = [1, 2];
foo(xy); /// fails
ushort x = 1, y = 2;
foo(x, y); /// works

sorry I was a bit sloppy in my previous post. Here it is corrected:
I was also curious whether there's functionality for the following (I

bool isStringLitteral(string); //tests whether a string represents a string
