writebytes(i);

interface IRawBytes { ubyte[] bytes(); }

In the above example you get a nice error message if int does not
have the bytes ufcs function.
missing: ubyte[] int.bytes()

Re: Little demo of allowing basic types to implement interfaces.
yes, it does seem to break if the Implements template func is in a different module to the free standing func. hmph, how to get around that.

I don't think it is possible. You can possibly have several modules with free standing functions with same signature which will match UFCS - how one may determine in general case which one to check against? Only way is to locally clone imports from the scope `Implements` is called from and I am not aware of any mechanism to do it. Well, one can always switch to string mixins of course and invade caller scope but that is not clean by any means.

Re: Little demo of allowing basic types to implement interfaces.
I have a basic solution but it can't handle basic types LOL! you have to
typedef them so that moduleName!T works.
and then the functions have to be declared in the same module as the type.
Or alternatively you have to specify the module to use e.g.
Implements!(T,MyInterface, mymodule).

I had to hard code the module name because dmd segfaults if you use
__MODULE__ in the contraint. Both references to asdf should be changed to
the module you are using.

FewDee: A library for 2D game prototyping
Hello, FewDee is an incomplete, experimental, mostly 2D, library focused on games prototyping. The official Mercurial repository is here: https://bitbucket.org/lmb/fewdee And there is a Git mirror here: https://github.com/lmbarros/FewDee This is work in progress. It is usable(*), but still needs lots of improvements. (*) I used an early version of FewDee in a prototype that worked even in a public demonstration ;-) I wasn't afraid of using D any features in FewDee, so I used (and even misused) lots of associative arrays, delegates, GC'ed memory... it might be interesting to see how it will behave in more demanding applications. My plan now is to stop working directly on FewDee; instead, I intend to actually use it in a few more game prototypes. Then, I'll use this experience to further guide the library evolution. Lastly, this is my first sizable D project, so destroy with kindness ;-) Cheers, LMB

Re: *Should* char[] be an output range?
On Wednesday, 4 September 2013 at 05:00:58 UTC, Jonathan M Davis wrote: The main problem has to do with what you do when there's not enough room to write to it. Even checking the length isn't enough, because it's unknown ahead of time whether a particular code point (or string of characters if calling put with multiple characters) will fit - at least not without converting the character to UTF-8 first, which would incur additional cost, since presumably that would result in it being converted twice (once to check and once when actually putting it). Of course, it's a problem in general with output ranges that we haven't defined how to check whether put will succeed or what the normal procedure is when it's going to fail. My first suggestion for that would be to make it so that put returned whether it was successful or not, but it's something that probably needs to be discussed. However, with that problem solved, it may be reasonable to make char[] an output range. But until we sort out some of the remaining details of output ranges (most particularly how to deal with put failing, but there are probably other issues that I'm not thinking of at the moment), I don't think that it's a good idea to change how char[] is treated, since how all of that is sorted out could have an effect on what we do with char[]. - Jonathan M Davis Thanks for your reply. Yeah, the debate always boils back down to what are arrays/input ranges output ranges, and what do we do when they are full (eg empty), and can we even detect it. I think that given your answer, I will simply *not* make them output ranges, but I *will* make sure that making them as such is easy. FYI (but it might need a little bit more work), I think I may be on to something. In my implementation, I defined a private function called doPut. doPut is basically the last atomic operation in the put functionality. Given a sink s, and an element e, it calls exactly the correct call of : s.put(e); s.front = e; s(e); It does *not* iterate over e, if it is a range. It does *not* attempt to check [e], and it does *not* transcode e. What this means is that basically, if you write doPut(s, e), then you are putting *exactly* the single element e into s. It means the s is a native output range for e: It doesn't need any help from put. From there, I defined the package trait isNativeOutputRange(S, E). If a pair S/E verify this Native variant of isOutputRange, then the user has the *guarantee* that put(s, e) will place *exactly* e into s. This is particularly interesting for: 1. InputRanges: if the range is not empty, the *put* is guarateed to not overflow. 2. Certain format functions, such as std.encoding.encode(C, S)(dchar c, S sink), will transcode c into elements of type C, and place them in the output range S. Here, it is *vital* that no transcoding happen. My doPut/Native trait help guarantee this. Well, right now, it is only used as private implementation detail, but it works pretty good. It might be worth investigating in more details if we want this public?

Getting anything more than 8 is really just wasted money, unless you have a *very specific* use case that requires it: Specifically, the only one I can think of is having a VM farm server. Or maybe some *super*heavy* image processing or video editing. Other than that, no, I would not cough up an extra +90$ for the +8 Gigs (I suppose +139$ is compared to the base 4 Gigs?). Especially when you can get a 128 Gig SSD at that price. BTW: About the hybrid drives. AFAIK, they used to be better than not hybrid, I guess but still leaps and bounds inferior to an SSD. That said, their algorithms get better every day, so I don't know. I think the real choice depends on what kind of storage volume you *need*. I'd *default* back to a hybrid, if having a single SSD didn't fit my volume needs. But even then, external 2.5 drives are dirt cheap nowadays, so...

For me only replacing @property fields with @property methods makes sense (with former prohibited to be taken address of and latter forced to be weakly pure).'

Recording and editing music eats up a lot of space, and GBs keep accumulating as I keep old versions of projects, original versions of images alongside the edited versions, download programs, libraries and plugins, maybe the odd VirtualBox installation (and I lack the discipline to transfer old files every X weeks to an external drive, just as I hate doing the dishes). I agree that 128-250GB are loads and it takes a while to run out of space, however, it happens faster than you think these days, because more and more stuff is stored on computers (music libraries, pictures, movies and whatnot). So I'm not sure about SSDs. They are still a bit too expensive (price / storage), in my opinion. But maybe if I build my own desktop, I could find a good compromise. A good solution would be a SSD for running programs and a SATA drive next to it to store the data. (Which is admittedly not too far from the external drive solution :)

Since the structs are declared empty, their 1-byte values don't
matter. So their addresses don't really matter either.
It has to do with the ol' 'identity vs equality'. In the example above,
a and b are not identical (do not refer to the same thing) and so
their addresses should not be equal.
The address of two 'named things' is the same if-and-only-if the names

How else would you do that? You can't replace field access with function call transparently if it has side effects. In the end breakage may be even worse. For me only replacing @property fields with @property methods makes sense (with former prohibited to be taken address of and latter forced to be weakly pure).' IIRC, foo.x with x a property should take address of return value of x(), which will either fail to compile or do the right thing if it returns a lvalue. So there's no undefined behavior as far as taking address of is concerned when replacing field by property. As for side effects, this is the reason one would go from field access to property, eg populating some data upon 1st access to a field x. Sure it can be misused, but I haven't seen a case in practice where it is misused.

Re: Had another 48hr game jam this weekend...
I *hate* shell scripting. My rule is if it is more than three lines, do yourself a favor and use a real programming language. This is equally true on unix and windows. Well, actually, the limit with batch might be one line rather than three. But still, shells are for interactive entry. Doing any scripting on them is a filthy, time wasting, bug-prone hack. (Especially on unix where you get idiocy like command line too long even trying to do simple tasks like deleting a bunch of files! Or the output to a pipe gets truncated due to terminal width - I kid you not, FreeBSD did that to me some years ago when I had to use it on a server. Drove me nuts.)
