Hi,

There is a way to determine all public properties (not methods) from a struct/class at compile time?

I seen that there are traits to get only methods but not properties. Am I wrong?

thanks,
Bogdan

You can get the function attributes of the returned methods using std.traits:

http://dlang.org/library/std/traits/FunctionAttribute.html

Vibe's serializer is also a good place to look. The code is a bit intimidating but it's handling a ton of corner cases:

Thank you for your response!

I don't think that it helps me...

I wanted to get an array like this [ "a", "b", "c" ] for this class

class test {


}

[sorry... this is the edit for the prev post]

Thank you for your response!

I wanted to get an array like this [ "a", "b", "c" ] for this
class

class test {

int a;
string b;
double c;

}

import std.typetuple: staticMap;
enum stringOf(alias thing) = thing.stringof;
static assert([staticMap!(stringOf, test.tupleof)] == ["a", "b",
"c"]);

It's better to use __traits(identifier) instead of .stringof.
