SHA256 Signature
Hi, How can I create a SHA256 signature hash in D? Something similar to the PHP code below: ```php openssl_sign($body, $signature, $secret, OPENSSL_ALGO_SHA256); ``` I've tried the code below without success: ```d auto signature = body.representation.hmac!SHA256(secret.representation).toHexString!(LetterCase.lower).to!string; ```

Often times, you are focused on something that isn't the problem, but *triggers* the problem. Not saying it's not a compiler error, it could be. But chances are pretty low. If you cannot get this to happen unless you use your custom writeln thing, I'd focus on trying to figure out if that custom writeln is doing something incorrect. All the code you posted here looks fine to me. It compiles and runs fine on run.dlang.io (even with the `version(none)` changed to `version(all)`, or using `scoped!B`). -Steve
Google Auth API
Hi, Has anyone here had experience implementing the Google Auth Library in DLang? Specifically, I am looking for guidance on handling OAuth 2.0 using JWT. Are there any current libraries available for this purpose?
Re: What's the latest GDC stable release version?
and GDC 14: https://gcc.gnu.org/git/?p=gcc.git;a=commit;h=09992f8b881aa2dfbee1e9d6954c3ca90cd3fe41 So GDC 14.1 includes the D language at v2.108.0. This is wonderful: Synchronizing with the upstream release of v2.108.0. BTW, if the following two pages are updated with version information, that will be great: https://dlang.org/download.html https://gdcproject.org/downloads
aligned struct field weirdness
Hello,
I'm having a weird case of access violation.
I tried to narrow the problem and put up a reproducible testCase
on compilerexploer, but it requires my framework too which
overrides std.stdio.writeln() in order to produce colorful text,
and logging, etc.
The error is an access violation when I access the struct in the
f() function.
Sometimes it can be fixed (marked the place.)
In one sentence: It is an aligned struct field, whose struct is
given to a class as a template parameter.
Maybe the weirdness is caused by the align(16)? When the fields
of the struct are placed on the instance of the class?
I know it's not reproduceable, maybe it was a bug that had been
already fixed. So I only ask if the situation is familiar to
someone, please tell me, what tricks I need to avoid.
I can avoid the align using dummy fields.
I can allocate the struct with new.
But it's a bummer, that the nicest version is unstable.
```
import het;
struct S
{
int a;
align(16)//<-this triggers it
int[4] b;
}
class A(T)
{
version(none)
{ T u; }
else
{
T* p; //<- this fixes it. (The struct is not on the class
surface)
ref u() { return *p; }
this() { p = new T; }
}
}
class B: A!S
{ void f() { writeln(u.text/+<-The access violation can be
here+/); } }
void main()
{
//writeln("a"); <- this fixes it
auto b = new B; //<-scoped! can trigger it too
b.f;
}
```
Thank You in advance.

Unshared is an eponymous template. https://dlang.org/spec/template.html#implicit_template_properties And it's using a shortcut syntax. ... The second template uses a template specialization https://dlang.org/spec/template.html#parameters_specialization No wonder I couldn't find it in the spec; I was looking for an "alias" language feature. alias as used here leans on a template mechanism--specialization. It might have taken many readings of the spec to have hunted that down, so--thank you. It's quite an interesting mechanism. D is quite easy for a C programmer to get started with, but it certainly has its depths! Andy
