Hi all,
This is a long shot but I'm out of ideas. I ported an app from Windows
to Linux and after many issues it is working but I'm left with a strange
problem. The app basically reads data streams from a USB device,
processes them and outputs real-time graphical data to a browser. There

I'm in the middle of porting a working D with C application from Windows

it seems that any pointer reference from C back to D is causing a crash.
Even passing the address of an int causes a segmentation fault when the

I copied a module because I am changing its form. The original is still

To answer my own question 'value.object["mode"].str' gets me there.

Hi
I'm trying to decode some json using std.json. I have figured out how to
get at primitives out but can't get to a dictionary object.
If I send something like {"mode":"am"} from my javascript and then say:
value = parseJSON(message);
I get a JSONValue struct. I can't find any documentation for

Hi
I'm just starting to debug some code and have run into a problem. There
is a bit too much code to post so as a first shot I wondered if anyone
has had this happen.
I have a thread in a read loop reading from a USB device. When it
accumulates enough data it dispatches it to another thread. Th
Thanks for the suggestions. I'm still hankering after an elegant
solution to the receive rather than try to patch it up after the event.
The best I can come up with is pretty ugly (odd) at the front but looks
better at the back-end. Maybe someone can refine it a bit.

I've been looking for a way to hook up messages to a thread with a
handler function. As far as I can tell receive pattern matching only
allows the pattern to be distinguished by the parameter signature which
does not help when all the handlers only have a few different signatures.

Hi
I'm stuggling with immutable.
I have a fixed size buffer which is used as a circular buffer of floats
and is effectively double buffering data I wish to transfer to another
thread. At an appropriate point I take the top half or bottom half of
the buffer and send it to another thread.

I'm trying out some very simple concurrency tests to make sure I
