It doesn't generate the right linker options for you to avoid the map file. I do it in Bud by not having DMD invoke the linker, instead I have Bud invoke the linker with the right options. The easiest way is to delete the .map files after compiling. Ok, so i created http://d.puremagic.com/issues/show_bug.cgi?id=2760 Thanks for the answer.
idup portable D1/D2
I want to make code compilable with D1+D2.
So i thought, i can make
version(D_Version2){
} else { // D1
string idup( char[] str ){ return str.dup; }
}
But this does not work.
D1:
str.idup; // compile error
str.idup(); // OK
D2:
str.idup; // OK
str.idup(); // compile error
Ideas?
Re: idup portable D1/D2
hm, the moment of pressing the send button is often enough a moment of
enlightment :)
version( D_Version2 ){
mixin(invariant(T)[] _idup(T)( T[] str ){ return str.idup; });
} else { // D1
String _idup( char[] str ){
return str.dup;
}
}
str._idup(); // compiles with D1+D2
digitalmars lib.exe, what does the pagesize mean?
What does the pagesize mean? When is it needed to increase? What is the cost?
LPT
Have you got any idea how to manipulate LPT port in Windows XP with D?

My computer is only a year old and has one LPT and two serial ports. The only traditional thing that's missing is a floppy drive.
dwt2 help
I filled in the Phobos implementation, but I'm not sure if it is all correct
as I don't fully understand the exception handling.
module java.lang.Byte;
import java.lang.util;
import java.lang.exceptions;
version(Tango){
static import tango.text.convert.Integer;
} else { // Phobos
static import std.conv;
}
class Byte : ValueWrapperT!(byte) {
public static byte parseByte( String s ){
version(Tango){
try{
int res = tango.text.convert.Integer.parse( s );
if( res byte.min || res byte.max ){
throw new NumberFormatException( out of range );
}
return res;
}
catch( IllegalArgumentException e ){
//How does this work? It catches e and gives it as an argument to a new
exception.
throw new NumberFormatException( e );
}
} else if version(Phobos){ // Phobos
try{
byte res = to!(byte)(s);
return res;
}
catch(Object e){ // ConvError or ConvOverflowError
//Is this the correct translation?
throw new NumberFormatException( e );
}
return 0;
}
}
this( byte value ){
super( value );

public static String toString( byte i ){
return String_valueOf(i);

Obviously NumberFormatException can store another exception object
inside. This code effectively converts IllegalArgumentException into
NumberFormatException, storing the original argument exception inside so
that one can examine it later if they're curious.
[...]
catch(Object e){ // ConvError or ConvOverflowError

It depends on what NumberFormatException can accept as an argument. If
it accepts an Object then it's fine.

Thanks, yes this is obvious...

class NumberFormatException : IllegalArgumentException {
this( String e ){
super(e);
}
this( Exception e ){
super(e.toString);
}
}
Can Object be implicitly converted to Exception?

No it cannot. Object is the root of the D class hierarchy. In D1
Exception is derived directly from Object. In D2 Exception is derived
from Throwable which in turn is derived from Object. You can cast
Exception to Object but not the other way around.
What's worse, ConvError and ConvOverflowError in D2 are derived from
Error which is a separate class from Exception and cannot be cast
implicitly. I think you'd want to fix the NumberFormatException to
accept Throwable for instance which is a base of both Exception and
Error in D2.
