Hi,
I have a bunch of square r16 and png images which I need to flip
horizontally.
My flip method looks like this:
void hFlip(T)(T[] data, int w)
{
import std.datetime : StopWatch;
StopWatch sw;
sw.start();
foreach(int i; 0..w)
{
auto row = data[i*w..(i+1)*w]
Hi,
Please help rewrite this code to D:

If you have to perform performance benchmarks then use ldc or gdc.
Also disable bound tests with your compilation switches.
Sometimes reverse() is not efficient, I think, it should be
improved. Try to replace it with a little function written

Hello!
I’m having issues with setting a cookie via CURL(std.net.curl).
I’ve tried several time over the last week but can’t figure it
out. I feel like I've tried every suggestion I found searching

Basically - I receive the value "set-cookie" from a GET request
(got this), but hav
There's two ways, you can let curl handle it by setting a cookie
jar file:
http://dlang.org/phobos/std_net_curl.html#setCookieJar
Make the HTTP object and set the jar on it before doing any
requests. Then it will be done automatically on that object,
saving to the file.

The class Node is contained within the struct BTree.
The field btFile is contained within the struct BTree.
The statement is within a function within the Node class.
I've tried many variations, here are a few:
btFile.write(self.nodeId, cast(void*)&(self));
results in:
need 'this' for 'btFile'

Sigh. I was hoping to preserve the determinate closing that one gets
with a struct.

Yess.but there are LOTS of nodes/BTree, and each node would need to
check whether the btFile was already initialized, et (ugh!) cetera. So
while possible, that's an even worse answer than depending on people
closing the BTree properly. I *am* going to separate the close routine

'cause `.codeof` is a can of worms. it is just a bad replace for AST
macros, and having it means that internal string representation shoul
std.algorithm.reverse uses ranges, and shamefully DMD is really
bad at optimizing away range-induced costs.
