Re: How to convert from ubyte[] to and from float?

What is the best way to convert from a part of a ubyte[] to a

I've tried converting the ubyte[] into a uint, but neither
casting the uint to a float nor to!float work.
I suppose I could use a trick record union, but that seems
inelegant. If I use pointers, the alignment may
(unpredictably) not be proper (whatever that means these days).
Is this what you're after?
http://dlang.org/phobos/std_bitmanip.html#.peek
http://dlang.org/phobos/std_bitmanip.html#.read
http://dlang.org/phobos/std_bitmanip.html#.write
These accept indices, or you can just slice the ubyte[] to the
part you need.

Re: Base class with member parameterized on type of extending class

I'm trying to make a game, and would like to set up the following
hierarchy:
At any time, the game is in one Scene. Each scene has a state machine
that manages States of type T, where T is the type of the scene (e.g.
Overworld, Menu).
abstract class State!T {
void update(T scene, float time, InputManager input);
...
}
class StateMachine!T { //manages states of type State!T }
abstract class Scene {
alias T = // type of class extending Scene
// methods pushState, popState, currentState access _stateMachine
private StateMachine!T _stateMachine;
}
class MainMenu : Scene {
// I want _stateMachine of type StateMachine!MainMenu
}
class Overworld : Scene {
// I want _stateMachine of type StateMachine!Overworld
}
class MoveToLocation : State!Overworld {
override void update(Overworld world, float time, InputManager input) {
// access properties of Overworld here
}
}
Within the Scene class, I've tried alias T = typeof(this), but that
appears to be resolved within Scene. This means that any Scene, such as
Overworld, have a state machine of type StateMachine!Scene rather than
StateMachine!Overworld. Since States are particular to a certain scene
and are designed to manipulate properties specific to that type of
scene, this would involve a lot of casting if States are not
parameterized. It feels like I need something like a class version of
the (this T) syntax used in templates.
This all smells a bit off though, so I wouldn't be surprised if the
answer is that I'm approaching this all wrong, but right now I'm not
seeing it.
You can always make Scene a template class:
abstract class Scene (T)
{
private StateMachine!T _stateMachine;
}
class MainMenu : Scene!(MainMenu) {}
But I'm guessing you like to avoid that if possible.

The reason for this was that the transitivity of shared was preventing me from calling pthread_mutex_lock or whatever because those functions didn't take a shared pthread_mutex_t. And attempting to rewrite core.sys.posix to make the logically shared types explicitly shared had a cascading effect that made me uncomfortable. Because of this, I remain unconvinced that the semantics of the shared attribute are actually correct when applied to user-defined types. I want some kind of an I know what I'm doing label, perhaps equivalent to the mutable attribute in C++, but to exempt contained types from shared. Thank you for that honest response. The situation is really bizarre. I just tried to create a shared worker thread and there is no ctor in Thread that creates a shared instance. Is a shared constructor even meaningful? [1] If yes, what do we need it for? Can't we otherwise just implicitly and safely cast to shared _after_ the constructor ran when we write `new shared(Foo)(...)`? Casting away shared is not @safe. Since this is normal to do in synchronized blocks, I figure the whole core.Thread and core.sync.xxx family are @system functionality ?

You're disabling the const version when T is mutable. Consider
const(Array!int): T is int is mutable, so there is no const
opSlice. But the Array itself is const, so the non-const version
can't be used. Do not disable the const versions of the methods.
Only ever disable the non-const ones.
Also, the opSlice we're looking at here is Array's, not
Array.Range's. You don't need to touch Array's methods at all.
Only Array.Range's non-const methods need special treatment,
because you need to catch the special case when the Range is
mutable, but the referenced Array is not.
And it's really `isMutableA!`, not `isMutable!T`. I guess you
went for that because `A` is only defined in Array.Range, not in
Array itself. But T's mutability isn't of interest.
For example, Array.Range.opSlice should look like this:
static if (isMutable!A) /* !A, not !T */
{
Range!(A) opSlice() {/* ... */}
Range!(A) opSlice(size_t i, size_t j) {/* ... */}
}
/* No `else`, the const versions should always be
available. */
Range!(const(A)) opSlice() const {/* ... */}
Range!(const(A)) opSlice(size_t i, size_t j) const {/*
... */}
Then there are still various methods of Array.Range left to be
`static if(isMutable!A)` guarded:
* move*
* opIndex
* opSlice*
By the way, since we're in D.learn, I'm assuming you want to do
this yourself. But if you'd like, I could make a pull request
with my suggestions to your branch.

Most people just need a basic appliance that isn't going to catch viruses or require registry hacks. LOL http://wmpoweruser.com/infected-android-phones-now-outnumber-infected-pcs-on-mobile-networks/ Are you laughing because of this? :) Android devices accounted for 60% of total mobile network infections, and 40% of mobile malware originated from Windows laptops connected to a phone or connected directly through a mobile USB stick or W-Fi hub. Infections on Windows Phone, iPhone and BlackBerry devices made up less than 1% 'Android smartphones are the easiest malware target,' said Kevin McNamee, security architect and director of Alcatel-Lucent’s Kindsight Security Labs, but noted 'but Windows laptops are still the favourite of hard core professional cybercriminals.'” Note my original reference to not being able to save files and the very low rate of infection on the iPhone. Android is a little different because it's so open, just like Windows, and I bet most of those infected Android devices were rooted or old. If you do the math, there are a lot more Android devices than Windows laptops, so the fact that there are almost as many infected Windows laptops means the infection rate of Windows is much higher.

All the more, those numbers reflecting infection rates on mobile networks.

Removing whitespace duplicates
How can I extend string line = carwash; line.strip.splitter!isWhite.joiner(_).to!string so that car wash becomes car_wash and not car___wash ? Used at https://github.com/nordlow/justd/blob/master/knet.d#L1142

Re: Removing whitespace duplicates
Justin Whear: std.string.squeeze might be more appropriate. But with tr you can also replace the spaces with the underscore. Bye, bearophile
Re: Really in need of help with std.container.array.d
Speaking of this module, since I cannot currently login to bugtracker, I'd like to note here that there are two major bugs in one little function: Array.Payload.length setter. One is this https://issues.dlang.org/show_bug.cgi?id=13619 and the other is reallocating without notifying GC of the pointers, which leads to having dangling pointers in the array after a GC cycle.
