There was a way to define new types within templates and I think that I

now. Can someone help me please?
I would like to do something like this:
template MyTemplate(T)
{
struct T ~ "Struct" // define FooStruct structure
{
int x;
}
class T ~ "Class" // define FooClass class
{
void bar(T ~ "Struct" t)

}
}
}
void main()
{
mixin MyTemplate!("Foo");
FooStruct t;
FooClass f = new FooClass();
f.bar(t);
}
Hopefully I am not mistaken.
Did you try string mixins? Maybe something like this untested code:
template MyTemplate(T)
{
mixin (CtfeReplace(q{
struct _T_Struct
{
int x;
}
}, "_T_", T.stringof));
mixin (CtfeReplace(q{
class _T_Class
{
void bar(_T_Struct t)
{
// ...
}
}
}, "_T_", T.stringof));
}

I'm thinking about the possibility of adding __gshared to all its static data. An alternative workaround would be to install Vista or 7, but although I do have a legal Vista install disk, I would prefer an upgrade since I don't want to reinstall all my programs. Also, my computer barely meets Vista's minimum requirements. I also might be able to rewrite lua.exe in D and preload my code in the executable. Most of Lua's functionality is in a library which would not need to be rewritten so this might be feasible.

Runtime error when accessing static data in a DLL
I'm writing a DLL in D which will be loaded (not automatically, but by LoadLibrary) by a C application (the Lua interpreter). I'm having problems with globals and static data. Everything is fine if I only access stuff on the stack, but as soon as I access a global or a static class variable, either the program crashes or if I am still in DllMain, the LoadLibrary function will fail and GetLastError will indicate an error with the message "Invalid access to memory location.". I'll work on reproducing it in a smaller scale, but does anyone know how to fix it? In case it is helpful info, in DllMain under the DLL_PROCESS_ATTACH case, I am just calling Runtime.initialize; even though the sample calls gc_init, _minit, _moduleCtor, and runModuleUnitTests.

I don't know what the problem is, but I would try checking to see if the
pointer at window construction and the this pointer before calling
onMouseDown are the same. Maybe there is a problem with using the result
of getWindowLong as a pointer. For example, one value could be 32-bits and
the pointer could be 64-bits. I didn't run the code to test anything, I'm
just throwing out some ideas which may be way off.

What exactly do you expect from supporting building? I use descent to build my project by using the external tool setup shown here: http://www.dsource.org/projects/descent/wiki/CompilingPrograms Well, I would like to just give it my dmd path and have it just work. I haven't managed to get rebuild to work yet. I think it has major problems with directories with spaces, and I do all my work in a folder within my user profile on Windows XP.

I hear Descent for Eclipse is getting support for D2 so you might want to start looking there, it does semantics analysis but Eclipse is too heavy an IDE for my tastes.
