D - Reference?

with D, or what the string manipulation functions are. Or maybe I just
misunderstood D and it doesn't have an extensive library built into the
language. Please enlighten me :) Thanks.

You could use:
GetTickCount();

 From std.c.windows.windows.

You probably want to look at phobos:

An *extensive* stl library is in the works however in my opinion much 
(not all) of the stuff  in C++'s stl is already available as part of the 
language in D.

The standard library ("Phobos"):
http://www.digitalmars.com/d/phobos.html

The library has room to grow. If you're looking for a particular string 
   trick that doesn't seem to be in the library, ask for a hint here. 
Somebody's probably figured out how to do it.

I've got some primitive examples on my website: 
http://jcc_7.tripod.com/d/tutor/. You're probably already too advanced 
for them. :)

Timing in milliseconds sounds like something that would be done through 
the OS. In D, you can directly access C functions 
(http://www.digitalmars.com/d/interface.html). I'm pretty sure someone 
has mentioned doing high performance timing in D, and surely they 
figured out how to do it, but I don't remember any details.

Actually it was in dig however I disabled the high-performace part (as 
it was causing problems) :(  You can go there to see the code I've 
commented out ).

In control.d

    /** Get the number of milliseconds the program has been running. */
    static ulong elapsedTime ()
    {
        ulong value;
        LARGE_INTEGER freq;

        return GetTickCount (); //Added by Joel Anderson
        /+if 
(!net.BurtonRadons.dig.platform.base.QueryPerformanceFrequency (&freq) 
|| freq == 0 || !std.random.QueryPerformanceCounter (&value))
            return GetTickCount ();
        if (!digPlatformElapsedTimeCounter)
            digPlatformElapsedTimeCounter = value;
        return (value - digPlatformElapsedTimeCounter) * 1000 / freq;+/ 
//Causes access volition -> fix yourself if you really want such accuracy
    }

There are a whole suite of timing classes in the synsoft.win32.perf module,
available from http://synsoft.org/d.html.

These are likely to find themselves in Phobos pretty soon, just need a
little "std."-ing. :)

Look into the samples at dhry.d.

So long!
