Indeed. dmd should warn about any incompatible data passed as variadic parameters. It's simple to decide: only fundamental types that correspond to C counterparts should be allowed. Hmmm... Even that's not that simple: int is 32 bits in D but unspecified in C. Maybe printf should not be visible at all - or under a different name (cprintf or something similar). It's just too tempting... C variadic arguments are one of the most unsafe features of the C language. A total mess. Stefan

Re: Latest versions of Entice Designer and DFL?
Greetings, I went to a second computer, and reDownloded Installed D/Dfl/Entice: dinstaller.exe , dfl098-installer.exe , entice08502.exe The following are A few more things that confuses and frustrates us newbies. 1) dinstall.exe creates 'C:\D\dmd2\'. 2) But Dfl-installer(dfl098.exe) looks for this 'C:\D\dmd\' and wont install without it. At least is said so. I don't know if dfl installed or not. Confusing. 3) Entice-installer(entice08502) installs here == C:\Program Files (x86)\Entice Trial and error, isn't my favorite MO. BTW: How can I see if things are installed correctly. I can edit myForm.d (from Entice Tutorial) with Entice, but can't yet compile. I am having trouble with the Compile Command. Entice keeps asking me for 'Compile Commands'. I tried a whole bunch of dmd.exe 'Keyword Options' like 'dmd.exe -D -quiet -Dddocdir -H', and even just 'dmd.exe' . But the best I could squeeze out of it was a list of Keyword Options. Can anyone help me with this? This is my fourth day of trying to get D/Dfl/Entice working correctly. Thanks...vm

I gave him some short instructions but apparently this post isn't in the archives for some reason.

E.g. if you've cloned the DFL repository to C:\git\dfl you could use this build.bat batch file: @echo off setlocal EnableDelayedExpansion set DFL_LIB=C:\git\dfl\win32\dfl\dfl.lib set DFL_IMPORT=C:\git\dfl\win32 dmd -I%DFL_IMPORT% %DFL_LIB% test.d and this would build test.d to test.exe.

Higher-order functions?
Hi everyone, does D have any runtime higher-order function facilities? (I'm not talking about templates.) More specifically, is something like this possible? (That's how I'd do it in Python) car_prices = map(Car.get_price, list_of_cars) car = new Car foobar(car.get_price) Thanks Jonas

You can use delegates. Example:
struct Car {
int price;
int wheels;
int get_price() { return price; }
int get_wheels() { return wheels; }
}
int sum(int delegate(Car) dg, Car[] cars) {
int sum = 0;
foreach (c; cars) {
sum += dg(c);
}
return sum;
}
void main() {
Car[] cars;
cars ~= Car();
... // add some stuff to the list
int total_price = sum((Car c) = (c.get_price()), cars);
int total_wheels = sum((Car c) = (c.get_wheels()), cars);
}

D has full runtime support for higher-order functions and closures.
import std.stdio;
int[] map(scope int delegate(int) f, int[] a){
auto b = new int[a.length];
foreach(i,x;a) b[i] = f(x);
return b;
}
void main(){
int a = 2;
writeln(map(x=a*x, [1,2,3]));
}
(I'm not talking about templates.)
You will often use templates together with runtime higher order
functions. Eg:
import std.stdio;
T[] map(T,S)(scope T delegate(S) f, S[] a){
auto b = new T[a.length];
foreach(i,x;a) b[i] = f(x);
return b;
}
void main(){
int a = 2;
writeln(map((int x)=a*x, [1,2,3]));
writeln(map((double x)=a*x, [1.6,2.7,3.8]));
}
For function literals that contain more than one statement, there is an
alternate syntax:
auto dg = (int a, double b){a*=b; return a+b;}
You can explicitly specify 'function' or 'delegate':
auto fp = function (int x) = 2*x; // not a closure, simple function
pointer (uses less space, but is less powerful)
int a = 2;
auto dg = delegate (int x) = a*x; // closure, can refer to a
You can leave out argument types when they can be directly deduced from
the context.
Finally, if the literal has an explicit 'function' or 'delegate' it is
possible to explicitly specify the return type:
auto dg = delegate int(int x) = x;
More specifically, is something like this possible? (That's how I'd do
it in Python)
car_prices = map(Car.get_price, list_of_cars)
car = new Car
foobar(car.get_price)
Thanks
Jonas
(Well, the standard way to do what that python code does is using templates.
auto car_prices = map!(car = car.get_price)(list_of_cars);// lazy range
auto car_prices = array(map!(car = car.get_price(list_of_cars)); //
eager array)

Yes. Fully. Many are already in the std lib:
http://dlang.org/phobos/std_algorithm.html
More specifically, is something like this possible? (That's how I'd do it
in Python)
car_prices = map(Car.get_price, list_of_cars)
Just as one example (These all work as of DMD 2.058):
import std.algorithm; // For 'map'
class Car {...blah...}
int getPrice(Car c) {return ...blah...;}
void main()
{
auto listOfCars = [new Car()];
auto carPrices = listOfCars.map!getPrice();
}
Or:
import std.algorithm; // For 'map'
class Car
{
...blah...
@property int price() {return ...blah...;}
}
void main()
{
auto listOfCars = [new Car()];
auto carPrices = listOfCars.map!( (Car c) = (c.price) )();
//or
auto getPrice = (Car c) = (c.price); // getPrice can be reassigned
at runtime
auto carPrices = listOfCars.map!getPrice();
}
car = new Car
foobar(car.get_price)
class Car
{
...blah...
int getPrice() {return ...blah...;}
}
void foobar(int delegate() dg)
{
auto x = dg();
}
void main()

auto car = new Car();
foobar(car.getPrice);
}
