"make -fposix.mak"
Am I forgetting something, or is "make -fposix.mak" supposed to build the DMD executable on linux. I'm just getting: make: Nothing to be done for `all'. This is on the zipped 2.054 release, from the "src/dmd" directory. It seemed to work for 1.066
Problem with take(map())
D2 code:
import std.stdio, std.algorithm, std.range;
auto foo(int p) {
return map!((int n){ return p; })(iota(3));
}
void main() {
writeln(take(foo(2), 20));
}
To me it prints:
[4221068, 4221068, 4221068]
Do you know if this is a known bug/problem?

@property makes it so that the function is used syntactically as a variable
rather than a function. And while it's not currently enforced, eventually, you
will _have_ to use property functions with the variable syntax. For instance,
empty on ranges is marked with @property:
assert(range.empty);
You could currently do
assert(empty(range));
but eventually that will be illegal. Property functions allow you to have
public member variables become functions (or functions become public member
variables) without having to change the code which uses them. They're
generally used instead of getters and setters.
In this particular case, the property function returns a ref, so it's both a
getter and a setter.

ref int value() { return m_value; } - uses?
What use is the property thing?
class Test {
private int m_value;
@property ref int value() { return m_value; }
}
void main() {
auto test = new Test;
test.value += 1;
}
Or this:
import std.stdio: writeln;
import std.conv: to;
class Test {
private string m_text;
ref auto text( string tx ) {
if ( tx.length > 4 )
m_text = m_text[ 0 .. 4 ];
return m_text;
}
override string toString() {
return text( m_text );
}
}
void main() {
auto test = new Test;
with( test ) {
text( to!string( test ) ) = "feet";
writeln( test );
text( to!string( test ) ) ~= "@";
writeln( test );
}
}

Re: Frontend and backend communication
Yes, this is a library, so a main() there would be rather pointless. However, it seems that on many occasions compilers will simply not acknowledge anything without one, so I guess at least a declaration is in order... I'll have to try that out once I get back on Windows. Meanwhile, on Linux, I am getting these linker errors instead: /usr/lib64/gcc/x86_64-suse-linux/4.5/../../../../lib64/libphobos2.a(datetime_3a6_1ec.o): In function `_D3std8datetime5Clock11currStdTimeFNdNeZl': std/datetime.d:(.text._D3std8datetime5Clock11currStdTimeFNdNeZl+0x1d): undefined reference to `clock_gettime' /usr/lib64/gcc/x86_64-suse-linux/4.5/../../../../lib64/libphobos2.a(time_c6_4d1.o): In function `_D4core4time12TickDuration12_staticCtor7OFNeZv': src/core/time.d:(.text._D4core4time12TickDuration12_staticCtor7OFNeZv+0x1f): undefined reference to `clock_getres' /usr/lib64/gcc/x86_64-suse-linux/4.5/../../../../lib64/libphobos2.a(time_c6_4d1.o): In function `_D4core4time12TickDuration14currSystemTickFNdNeZS4core4time12TickDuration': src/core/time.d:(.text._D4core4time12TickDuration14currSystemTickFNdNeZS4core4time12TickDuration+0x1f): undefined reference to `clock_gettime' Is it related, or is it a different issue altogether? Also, apparently SDL and Lua don't like being statically linked. Good thing the backend doesn't use SDL any more, then! And Lua does link, although reluctantly and with linker warnings. Reportedly they are nothing to worry about too much, but still...

Yes. I bet even an empty program has on the order of 50 module ctor/dtors to run. All the runtime can contain module ctor/dtors, and those modules are compiled in no matter what. Plus dmd adds hidden modules with ctor/dtors. There are other initializations, such as the GC, setting up the main thread, etc. 0.11 seconds is not unreasonable. It means about 170_000_000 CPU clock ticks, to me it seems a lot. I guess if you want to have an empty program benchmark? It doesn't seem to mean much to me... If it was on the order of seconds, I'd agree with you. .11 seconds is barely noticeable. But I'll also stress that timings at this precision can be fairly volatile. I think this timing precision is not so bad. What I mean is, the timing for a program can easily vary by 10ths of a second between runs, depending on what's happening on the computer. Make sure you do an average, and not a single run to do these kinds of tests. -Steve

If I'm not mistaken extern() accepts only Identifier, not expression.
I'm not really sure what's the best way to do that but I belive this
should work (haven't tested):
enum code = q{
void func() {
// do something
}
};
version (Windows) {
extern (Windows) {
mixin(code);
}
} else {
extern (C) {
mixin(code);
