Derelict linking (Debian + derelict + dmd 2.062)
Hi! I am trying to add SDL support to my project. libderelict-dev installed into my Debian and I am just added import derelict.sdl2.sdl;.

Re: Bug or feature?
Well, how you can reduce the long ugly name in this case? In the real function I mentioned it so many times.

:P
By the way, yes. Thanks for that, I'm stupid today.
Re: How do you guys debug large programs?

The lack of nice IDE's with integrated debuggers is worrying when working with D but up until now i haven't need one. Now i've started to write much larger programs, i'm wondering which debuggers do you use? Especially using Linux. I am use Geany + gdb in Linux. A little frustrating that the Geany's GUI don't shows CPU registers, but . Need to compile with this arguments for working with gdb: dmd -unittest -gc -debug -debug=5

In the real function I mentioned it so many times. By not making the name ugly big. Other people do. In addition, sometimes you want to cut long nested queries such as: auto numOfPixelsDisplayed = Table.getItems( Scene.getObjectsArray() ).prepareForDisplay( type.GL ).showScene();
lookup fields struct
Hi!
I am want to get list of fields types and offsets in struct by
the template.
I.e., lookup through this struct:
struct S {
int a;
string b;
someptr* c;
};
template Lookup!( S )(); returns something as:
field #0, int, offset 0
field #1, string, offset 8,
field #2, someptr, offset 16
How I can do this?
Bug or feature?
import std.stdio;
struct S
{
int bigUglyName;
void foo( S s )
{
alias bigUglyName local;
alias s.bigUglyName b;
writeln( bigUglyName (AKA local)=, local, b=, b );
}
}
void main()
{
S s1;
S s2;
s1.bigUglyName = 1;
s2.bigUglyName = 2;
s1.foo( s2 );
}
returns to console:
bigUglyName (AKA local)=1 b=1
Why? I am expected that b=2
Re: lookup fields struct
Wow! thanks!
