Hi,

I attempted to use a combination of traits and mixins to automatically create aliases of names in SDL2 without the SDL_ prefix for convenience. However, I was only able to achieve this for functions in the module, and not for types nor enum values. How could I go about achieving the desired result? Here is the code I'm using in an intermediate "sdl_stripped" module:

import std.regex;
import std.array;
public import derelict.sdl2.sdl;

string StripSDLPrefix() {
    auto members = [__traits(allMembers, derelict.sdl2.internal)];
    foreach(ref member; members) {
        if (member.length > 4 && member[0..4] == "SDL_") {
            member = "alias " ~ member[4..$] ~ " = " ~ member ~ ";\n";
        }
        else {
            member = "";
        }
    }
    return members.join();
}

mixin(StripSDLPrefix());

// I added this to print the list of generated names for debugging purposes.
static if (false) {
    pragma(msg, StripSDLPrefix());
}

Hello, as I know allMembers returns members not recursively. If you want to get really all members you need to make recursive function. In my program I used the next routine to print all members of module:

static void allMembersOfModule(string module_name, bool root=false)()
{
    static if (module_name != "object" &&
        module_name != __MODULE__)
    {
        mixin("import "~module_name~";");

        pragma(msg, module_name~":");

        foreach(member; __traits(allMembers, mixin(module_name)))
        {
            static if (__traits(compiles, mixin(member)) &&
                (!__traits(compiles, __traits(getProtection, mixin(member))) ||
                __traits(getProtection, mixin(member)) != "private" &&
                __traits(getProtection, mixin(member)) != "package"))
                pragma(msg, member);
        }

        static if (root || module_name == "std.algorithm" || module_name == "std.range")
        {
            import std.algorithm.searching: startsWith;

            foreach(member; __traits(allMembers, mixin(module_name)))
            {
                static if (__traits(compiles, mixin(member)) &&
                    __traits(compiles, mixin(member).stringof.startsWith("module ")) &&
                    mixin(member).stringof.startsWith("module "))
                {
                    allMembersOfModule!(member);
                }
            }
        }
    }
}

As I know it worked good. Maybe it helps to you also.
