Floating point literal definition
I'm currently reading about floating point literal and came to this
part:
FloatLiteral:
...
Integer ImaginarySuffix
Integer FloatSuffix ImaginarySuffix
Integer RealSuffix ImaginarySuffix
Going to the Integer link, it is defined as:
Integer:
...
BinaryInteger
and BinaryInteger is defined as:
BinaryInteger:
BinPrefix BinaryDigitsUS
This program produces the error: semicolon expected, not 'b01f'.
void main()
{
double d = 0b01f;
}
So, does D allow floating point literals in binary format or not?
If not then the floating point literal definition is a bit misleading.
Or maybe someone had already filed a bug report on this?

DMD64 D Compiler v2.070-devel-5123284
Inline assembly and Profiling
I'm working on a chess engine side-project, and I'm starting to
get into profiling and optimization.
One of the optimizations I've made involves some inline assembly,
and I ran across some apparently bizarre behavior today, and I
just wanted to double-check that I'm not doing something wrong.
Here's the behavior boiled down:
import std.stdio;
ubyte LS1B(ulong board)
{
asm
{
bsf RAX, board;
}
}
void main()
{
auto one = 0x939839FA;
assert(one.LS1B == 1, "Wrong LS1B!");
}
If I run this through DMD without profiling on, it runs
successfully, but with profiling on, the assertion fails. And in
the actual code, it returns seeming random numbers.
Is the profiling code stomping on my toes here? Am I not allowed
to just single instruction into RAX like this with profiling on?
Or is this just a compiler bug?

It's the same as in C. Assuming that you have a ./libxyz.so that

Say, for example, `data` is used by a class that is globally

public string getData(string key)
{
if (key in data)
return data[key];

I'm almost sure that built-in AAs don't provide automatic
synchronization (in my tests I hit a deadlock), but you can
easily wrap the AA into a struct that does the necessary
synchronization. However be aware that even then you are not
going to be safe, because more than one thread can try to access
the keys or the values of the AA. Also note that because the
built-in AAs rely on the GC, you may get poor scaling because
every memory allocation can potentially take the global GC lock,
which will block all threads from doing any work. So do your own
tests and if you find the need to improve the performance, I
would suggest investigating replacing the built-in AA with (for
example) the hashmap from
https://github.com/economicmodeling/containers in combination
with a thread-local allocator.
Here's an example of how to wrap an AA into a moderately safe
accessor. In the following example I create an additional thread
which concurrently adds odd numbers into the AA, while the main
threads add even nubmers:
http://dpaste.dzfl.pl/06025e6374eb
It segfaults on DPaste because you can't create threads there,
however it works ok on my machine. The output look like this:
"0" : 0.140450140112896
"1" : 1.140450129700608
"2" : 2.140450140112896

Re: Why we cannot use string in mixins?
On Sunday, 28 February 2016 at 03:08:14 UTC, mahdi wrote: Thanks. So the author was plain wrong about using enums instead of strings. The misconception is due to assuming we can use `string` variables at compile time but we cannot (as they are run-time data). Not exactly either. #define str "My string for use" In C people know the processor which creates a "manifest const." In D, it was chosen to reuse enum as the keyword to declare manifest const. enum string str = "My string for use"; But in D, we don't required declaring the type everywhere so you can just specify a storage class: const str = "My string for use"; Combine the things together and you create a compile time string without specifying that the type is string. enum str = "My string for use";

Re: Why .length on Windows is int and on Linux is ulong?

On Windows, the compiler flag -m32 is the default, regardless of dmd's bitness [1]; on Linux it's -m64 for 64 bit dmd [2]. That's what causes the different sizes. Use size_t for lengths, not int or ulong or any other specifically sized type. By the way, with -m32, size_t is uint, not int.

Its not OS dependent, its arch dependent. On Windows you are building in 32bit mode but on Linux 64bit.
