If the patent passes for whatever reason, this becomes a valid point if and only if you have the resources to contest its validity. The patent holder can effectively strongarm you into paying for licensing unless you have the (upwards of) hundreds of thousands of dollars needed for lawyer fees. They need only to drag out the court proceedings to starve you monetarily and win by walkover. It's not a far stretch to make an analogy to protection rackets, and it seems to me that the very point of patents has been subverted.

git show "previous tag"
Anyone here knows how to consistently obtain the previous tag on git? Currently, the installer uses: git describe --abbrev=0 v2.067.0-b1^ This does not always retrieve the correct tag though. In this case the tag prior to v2.067.0-b1 is v2.066.0, however this command returns v2.066.0-b1. This causes a problem because v2.066.0-b1 broke the installer and cannot be used to build DMD. To get around this issue, I usually upload a different version of the compiler in place of v2.066.0-b1. This is not the ideal solution because anyone downloading that v2.066.0-b1.zip will not be getting something completely different. Assistance appreciated. Regards, Andrew

Re: SWIG?
I've used it quite a bit for a number of bindings (opencv, sfml + many other libs). It's much easier than the conventional approach of manual bindings (eg deimos), especially to keep the port up to date with upstream changes. However the following should be worked on: * support for newly introduced C++ namespaces ( https://github.com/swig/swig/issues/213) * some support for multiple inheritance (I proposed using alias this in https://github.com/swig/swig/issues/98) * mapping of C++ templates to D templates in simple cases at least (the templates would have to be instantiated somewhere in source file of course to avoid linker errors). Only the function signature would be mapped, the implementation would be still on C++ side * miscellaneous compiler warnings that shouldn't be hard to deal with - Deprecation: Read-modify-write operations are not allowed for shared variables : has a pull request (https://github.com/swig/swig/issues/203 ) - missing override * it would help to have a dedicated bug tracker for D-swig. Currently github issues for swig lump all other languages together, making D-swig of limited visibility for D community. At least create a SWIG-D label in github issues. @klickverbot will tell you more as he implemented most of it IIRC On Wed, Aug 27, 2014 at 6:08 PM, Scott Wilson via Digitalmars-d < digitalmars-d@puremagic.com> wrote: > SWIG has D support.

In my opinion this should always give you a compiler warning, as it is not portable to 64-bit: uint func(size_t i) {return i;} But that has been discussed and reported to death already :D I'm also somewhat pedantic about assigning unsigned to signed types and vice versa.

But recall I did implement it in DMC++, and it turned out to simply not be useful. I'd be surprised if the new C++ support for it does anything worthwhile. Well, one should initialize with signaling NaN. Then you get an exception if you try to compute using uninitialized values. That's the theory. The practice doesn't work out so well. To be more concrete: Processors from AMD have signalling NaN behaviour which is different from processors from Intel. And the situation is worst on most other architectures. It's a lost cause, I think. The other issues were just when the snan => qnan conversion took place. This is quite unclear given the extensive constant folding, CTFE, etc., that D does. It was also affected by how dmd generates code. Some code gen on floating point doesn't need the FPU, such as toggling the sign bit. But then what happens with snan => qnan? The whole thing is an undefined, unmanageable mess.

Personally, I don't believe DUB can succeed at having multiple supported config languages - one or the other will win out over time, and users will diverge. So no language would meet that bar (in my opinion). Mostly we are talking about JSON+stuff as an additional language... so can it be reframed as 'additional features you can use in your dub config file, that aren't strict JSON'? Framing things this way, you could (for example) switch DUB entirely over to ASON, and avoid the 'switching to a new language' arguments. DUB takes JSON, DUB also accepts not-strictly-JSON syntax like comments, etc.

Hulk Not Want!" Well...or something vaguely sorta kinda like that ;) That's justified, because SDL fails to not surprise. Curly brace syntaxes are not line-delimited not requires backslash line continuations. Yea, I'll grant it *is* somewhat of a blemish in SDL's design. But I don't think it's a critical one. Besides, this thread's (dare I say "bikeshedded"?) quest for an ideal data language seems doomed from the start: If we try to avoid the less common ones, and avoid inventing our own (which I think we have good reason to avoid), then everything left *does* have imperfections. Therefore, I think the main critera we should be looking at here, for any of the possibilities, isn't "Does this language have flaws?" but rather "Is this language *good enough* to be supported by DUB as a JSON alternative?" Like JavaScript for example? Heh, there is that. What's wrong with XML? I work with it daily and see no problem. The less syntax a language has, the worse it scales, and if it doesn't scale, its adoption creates a technical debt. 100 lines with 3 levels of nesting and JSON becomes hard to follow and TOML becomes simply unmanageable. The reason to search for an additional format is to make it more convenient and readable for human interaction. XML wouldn't structurally a bad choice, but is awful because of it's syntactical overhead. That's a big one. *The* big one in my mind. Additionally, despite XML's simplistic appearance, some of the details about it get disturbingly over-engineered. Heck, take a look at W3C's docs on it: for something that's *supposed* to be as simple as: blah For something that *appears* to be that simple, it's formal reality is horrifically complicated. Besides, there's nothing stopping a good editor from taking this: { "tag1" : { ...blah, blah, blah, blah... ...blah, blah, blah, blah... ...blah, blah, blah, blah... ...blah, blah, blah, blah... } } And adding helper visuals (not part of the actual document) to display it as this: { "tag1" : { ...blah, blah, blah, blah... ...blah, blah, blah, blah... ...blah, blah, blah, blah... ...blah, blah, blah, blah... } "tag1" } {root} (The wouldn't be displayed, I just put them there to indicate the text inside would be visually distinguished so that the user finds it obvious it's not actually part of the document. Can't really emulate that in a NG post.) I don't know why no editors ever do that.

What happens when I pass identifiers to scope!(…) return types? - Can the compiler look up the identifiers' types and scopes in all cases? It has to be able to. If a non-visible identifier is specified, it is an error. - Will the compiler deduce the return type from these identifiers? E.g. "scope!(someString) ref getString();" will work like in your example? I don't think so, because the "lifetime identifiers" could be structs containing the returned type. I see, this was a stupid mistake. Of course this function needs to specify the full type, as no type deduction can happen when the body isn't available. Fixed in on the Wiki. - What if we used incompatible types like "scope!(someString, someIntPtr)" there? - What about variables? Just to be sure: You can only specify variables as owners, not types. I've clarified this on the Wiki. static int someInt = 32; string someString; scope!(someString, someInt) int* x; x = &someInt; Is the declaration of x in error? Strings don't contain integers unless unsafe casts are used, so why would they narrow the lifetime of an integer reference? This is an interesting thought... But I would still allow this for a different reason. At the beginning, I only thought about `scope` as a tool for memory management, but I believe it can be applied for lifetime management of arbitrary resources. Let's slightly modify your example, and use different types: Task someProcess; scope!someProcess HANDLE my_handle; `someProcess` could represent an external process that is managed by this program, and `my_handle` could refer to some kind of object in this external process. This handle is only valid as long as the process exists, even though it is not a memory reference, and `Task` might not contain any members of type `HANDLE`. (This is not an ideal example, of course, because the process could terminate for reasons outside of our control.) A similar example would be a connection to the X server, and a handle to an object allocated from it. I already wrote this idea into the section "scope for non-reference types", with a simpler example. In fact, I believe that the entire proposal will be a bit simpler if references/pointers aren't treated specially. - Is it necessary to keep around all declared lifetime identifiers? In the snippet above (assuming it is valid), it looks like the shorter lived `someString' is enough to establish the semantics. Yes, it's possible to some degree, see the section "Considerations for the implementation". Unfortunately, this doesn't work with function declarations, and is incompatible with the suggested `scope!(const ...)` extension.

Sure, the data to build a new "dub.json" is in there - after all, all the data DUB can provide is in there. But that's the problem - *all* the data DUB can provide is in there. That includes data from downloaded dependencies, system data, (possibly) local configuration data and anything can be added in the future. That's the point of `dub describe` - query for anything DUB can tell you and let the user pick what they need. Even if the result of `dub describe` were valid for "dub.json", you wouldn't want to put all that data in the project's build-file! You want to be able to put "dub.json" under source control and for that it must only contain information about the project - not about the specific configuration of the machine of the last developer who happened to run `dub describe` and overwrite "dub.json". `dub describe` is perfect for automated tools that want to query DUB, but it's not a solution for tools that need to modify it.

Yes. dub is most definitely facing this problem at this minute. Are lots of devs venting their spleens over not being able to include comments, heredoc strings and such in dub files? The dub registry is gaining traction lets not throw an obstacle in the road now. heredoc's is a new one, but comments/nesting/trailing commas/unquoted strings, yes, most assuredly yes. Have you not been reading people's concerns about JSON? How could you say that people aren't complaining? Also inventing a Frankenstein format that is both a superset of Json and SDL just sounds horrible and just sounds wrong. It's just too much. Your effort would be better directed to something which is an immediate problem. Not re-inventing this particular wheel. I most definitely wouldn't call ASON a "Frankenstein" format. I didn't design ASON to be a superset of SDL, that's just how it worked out. Just like YAML happens to be a superset of JSON. Instead of saying it "sounds horrible and just sounds wrong", why don't you look at the language spec and say what is wrong about it. It's fine if you think we shouldn't use a new language but even if no one ever uses it, it's helpful to know what features people think are good/bad so we can all learn something. Sonke has said Json will always be an option in dub. Which is fantastic because now that dub has reached an official level as the de-facto package manager we need to embrace stability and stop this needless change which has been plaguing D forever. Yes, JSON will always be used to represent the package format on the back-end. So it makes sense to allow users to use it on the front-end if they wish. And again, adding a new format isn't a "needless change", why do you think so many people have such strong opinions about what format to use. You seem to be one of the only ones that thinks adding a new format (or using "lenient JSON") is a bad thing. I honestly think Ason should be abandoned as an unneeded solution looking for a problem and something more stable and recognised like Yaml or XML, etc. implemented in future *if needed* and actually if requested by dub's users. You seem to be stuck on the idea that I think DUB should use ASON. I created this thread so I could learn from other people what they think about this format and others. Even though you haven't added anything helpful, after reading other people's posts I'm now leaning more towards SDl. My biggest complaint is that it might be confusing for people to go between the SDL version and the JSON version. However, Sonke thinks that he can make a much more friendly package format with SDL's extra features like tag values/attributes.

However using strict JSON for build configuration prevents users from commenting out sections temporarily, and also rejects text that can be understood by a human but doesn't follow JSON's strict rules. It also becomes very unwieldy when any amount of nesting is involved. Then again, when you start writing data formats that are easier to write for humans, you start getting complicated.

Re: RFC: scope and borrowing
Marco Leise: The amount of possible use-cases you listed for this extension is staggering. With scope management in code like this: import std.stdio, std.algorithm; int foo(in int[] a) { return sum([0, 1] ~ a[1 .. $ - 2] ~ 0 ~ [a[$ - 1] + 1, a[$ - 1] + 2]); } void main() { int[5] b = [10, 20, 30, 40, 50]; b.foo.writeln; } The compiler in theory could lower the code to something like this, removing all heap allocations for the array literals and the concatenations, allowing 'foo' to be annotated with @nogc (I don't know if Rust is able to do this, I presume it can): import std.stdio, std.algorithm, core.stdc.stdlib; T foo(T)(in T[] a) @nogc { immutable size_t L = 2 + a.length - 3 + 1 + 2; auto ptr = alloca(T.sizeof * L); if (ptr == null) exit(1); // Or throw a stack overflow error. T[] b = (cast(T*)ptr)[0 .. L]; b[0] = 0; b[1] = 1; b[2 .. $ - 3] = a[1 .. $ - 2]; b[$ - 3] = 0; b[$ - 2] = a[$ - 1] + 1; b[$ - 1] = a[$ - 1] + 2; return sum(b); } void main() { int[5] c = [10, 20, 30, 40, 50]; c.foo.writeln; } But in some cases you don't want those arrays to be allocated on the stack because you know they are very large. So the [...]s array literal syntax becomes useful again: import std.stdio, std.algorithm; int foo(const scope int[] a) { return sum([0, 1]s ~ a[1 .. $ - 2] ~ 0 ~ [a[$ - 1] + 1, a[$ - 1] + 2]s); } But this is still not enough, because even if those parts are all safely stack-allocated, the result of the concatenation is still not stack-allocated. This could be enough: import std.stdio, std.algorithm; int foo(const scope int[] a) @nogc { auto[$] a2 = [0, 1]s ~ a[1 .. $ - 2] ~ 0 ~ [a[$ - 1] + 1, a[$ - 1] + 2]s; return sum(a2[]); } Bye, bearophile

Thus, they seek to get ownership of the word/idea/concept (which is ridiculous of course) to (pre-emptively) knock out others (or get money for it by licensing it to others, including those they stole it from).

It's not _that_ strong. Also, this is a library problem. I'd suggest you file a bug report/enhancement request against Phobos, if it is not already there. https://issues.dlang.org/ It seems that adding some constructor(s)/opAssign(s) to Nullable will solve this problem. ( BTW: You are more likely to get a quick response if your post looks a little bit more digestible, like: On 08/26/2014 05:38 PM, Uranuz could have written: // --- import std.typecons; void main(){ Nullable!ubyte x; Nullable!int y=x; // AssertError: Called 'get' on null Nullable!ubyte } // --- import std.typecons; void main(){ Nullable!ubyte x; Nullable!int y; y=x; // AssertError: Called 'get' on null Nullable!ubyte } // --- Is this a bug? Or you could have gone straight to https://issues.dlang.org/. :) ) The last example is even more obvious but didn't come to my mind. Maybe I'l think of better implementation myself and push something to standard library. The best way to make something working is to do it myself [jokingly] If I could write multiple alias this in Nullable I could create implicit conversions from Nullable!byte not only to byte but also to Nullable!short, Nullable!int. In this case there is no need to implement lots of overloads for property of type Nullable!int in order to correctly accept Nullable!byte, Nullable!ubyte and so on. I have wrote an example code and seems that only fixing Nullable implementation will not help to eliminate the problem I was talking about. So I have a choice: 1. Implement Nullable type without *alias this* at all (and access to internal value with getter method or property) 2. Implement lots of overloads of virtual Nullable!int property to accept every minor integer types. Also is needed to forbid Nullable!uint conversion because it is incorrect. I can't correctly store uint.max inside int variable, but implicit coversion is allowed in the compiler (and it is not documented). Because using alias this makes code shorter I prefer it, although it is very tricky feature and needs attention during development.

On Tuesday, 26 August 2014 at 22:07:49 UTC, Jeremy Powers via Digitalmars-d wrote: If your users are having to install things then the problem is your deployment mechanism not the JVM dependency hell system. Java deployments are actually really quite easy. Either you package a total system with all dependencies and provide entry scripts, or you use Maven Central (or increasingly BinTray) for accessing dependencies. If I need deployment mechanisms like the ones above, then there's something wrong with the language. All these crutches and patches. To set up and test a deployment mechanism takes as long as writing the program. No thank you. This is what you get with shared libraries. If you don't want to deal with dependencies, either A) ship a static-linked binary or B) cross your fingers and pray. Statically linked binaries are still the best option, if you want to make sure things will work for the user (and you don't have time for customer service). It's also a good strategy for cross-platform development, this or you have to use an approach similar to Textadept that ships everything in one package. I usually ship all the additional dlls / libs, if there are any. Relying on system wide dynamic linking is more for cases when you develop for one particular environment or when you're 90% sure that a certain library exists on most systems you develop for. The C standard library comes to mind, but even there are differences between Linux and Windows. And don't forget that, unlike Linux users, people who use Windows are usually not tech savvy in the sense that they can deal with downloading additional libraries. It all depends on the products you're developing. But for our stuff it's better to go static or ship everything. I've found the java ecosystem to be quite well fleshed out and mature in handling lib/jar dependencies, such that it was an unpleasant shock dealing with C++ after years away. Using maven, for instance, is a quick and easy way to abstract the problems away (though it is better suited for builds than deployments). As D gets more support for dynamic libraries, it would be good to take lessons from how Java and others have dealt with dependency management. Yes, only better. :-)

It's a seriously bad use of $10k. The best defense is prior art, and there's a ton of it. I say this having my name on a handful of applications and one granted patent.

Surely that counts as prior art?? Does the patent office accept prior art submissions? T They do. http://meta.patents.stackexchange.com/a/107 I don't like that. Even if we want to break this patent with prior art, we need to publish one for ourselves. This system sucks, we can't choose not to be part of it if we want to be protected.
