Okay. I'm trying to get some C code to be properly callable from some D code,
which naturally involves some extern(C) blocks. One of the types that I have to
deal with looks something like this:
typedef struct
{
unsigned i:1;
} my_struct;
I have no idea how to do such a
Hello,
Does dmd inline when appropriate (eg single-line func)? or is there a hint
keyword? or what else?
Eg how to have this inlined:
private bool isPrecomposedHangulSylable (Code code) {
/** whether code is a precomposed Hangul syllable ;-) */
return (code = FIRST_HANGUL_SYLLABLE)

Is there a thing like C's exit() for a D program? Is
simply using C's function good enough?
Also take a look at core.runtime.Runtime.terminate()

I haven't tried but maybe htod can help, try copypasting the code to a
header file and run it through htod. There's also some flags htod can
take to simplify the output, iirc. But maybe htod isn't clever enough
to do bitfields..

Hello D people,
Is there a way to unpack an array into local vars, as:
auto x = [1,2,3];
a,b,c = x;

No. There is no way to do multiple assignments to the left of an assignment
operator. The only way that you can do multiple
Hello again,
I started to be found of defining types which basically are arrays with free
functions, instead of creating a struct or class with methods. Not only we
still have pseudo-method syntax (for arrays only), but this allows customizing
the type when needed.
But: is there a way to

Not yet, but I have asked this feature for tuples too and maybe someone has
appreciated it.

(opEquals, opIndex, toString...) without creating a true type?
You may find some trick to do something like that, but it's not how D is
supposed to be used. In D operators belong in a struct/class/enum. alias
Stanislav Blinov:
I'm under the impression that
struct my_struct
{
mixin(bitfields!(
uint, i, 1,
uint, , 31));
}
should do the trick.
But bitfields in C may not use the same alignments used by bitfields!() on DMD
so I think you have to test the sanity of the whole thing for each

hm... what alignments are you talking about? bitfields
