Re: What would be the advantage of using D to port some games?

The derelict-* packages are being superseded by bindbc-* packages as far as I know, so bindbc-sdl is probably what you want now: https://code.dlang.org/packages/bindbc-sdl

C/C++ has tons of these and many of these are being actively developed, so why D cannot have? Especially when it is aiming to replace C/C++. Argument that VSCode is pretty much enough for most task it is ok, but is not very valid. The same applies to D itself - why to make a new language then when there is C++ around and there is a tons of IDE's for it. Personally I feel this is more about lack of the vision, as Alexandrescu once said. Now it feels like D is mostly the compiler, but I think, that having one big mega project (like IDE+RAD) could give a new breath and significance to D language. Making an entire IDE would be a lot of work. Making plugins for existing editors is already time consuming, and is less work than building a complete solution. Given how powerful regular editors can be, whether it's VSCode, Vim or Emacs, plugins make for a good compromise bewteen the time spent making the plugin, and the result you get.

Re: a way of approximating "API internal" visibility?

Sometimes I have symbols that I would like to share between internal packages, but I don't want to make 'public' because then it would be exposed to the client-facing API. To a degree this could be gotten around by making things public internally, and then selectively 'public import'-ing individual symbols in the topmost client-facing module (vs. entire packages, as I'm doing now). However I have the following situation for which that won't work: I have a class that's going to be visible to the client, but inside that class I have methods that should only be accessible to other internal packages. So neither 'public' nor 'package' is what I want. I already collapsed one level of what I was doing to get around this issue (putting things in a common package even though I would have preferred they be in separate, sibling packages), but I'm not sure I could do that again without making a mess. Is there some way of approximating an access specifier between 'package' and 'public'? Or am I likely just structuring things very badly to begin with, to even have this problem? I'm not much of a C++ guy but I'd probably resort to using 'friend' to get around this, at least in the case of classes. Maybe what you need is `package(a.b.c)`? ``` my/lib/internal/foo.d // This function should be visible from any package that has my.lib in its package hierarchy package(my.lib) void func(); ``` https://dlang.org/spec/attribute.html#visibility_attributes However, I don't know what you could do if you want to share code between completely different package that don't have a common root.

Good example for this is dlib (https://github.com/gecko0307/dlib). It has many functionalities that could be split into separate packages. The way I see it the advantage of smaller packages is that users can pick and choose and and only have the code they really need in their project, but the con could become managing a lot of dependencies. Also I am not sure how compile time on clean project and previously compiled project would be affected. I'd use subpackages in such cases. This way you can either have one dependency on the whole thing, or select only a few subpackages.

It's confusing and I think this could be handled better by the distro. But this is also one of the reasons I'm not a fan of dub. The user is left to sort through these dependencies themselves, and that means it's really not suitable for packages that link to C code (which is most of what I do). One of the main selling points of D is its C interoperability, but a lot of new users would walk away rather than trying to figure this out, concluding that D is buggy. I don't think it's confusing, you will also need to install the development package if you are coding something in C. It's the same, except for the language being D instead of C. As D is advertised as a systems programming language, this doesn't seem confusing (to me, at least). If a dub package uses a system library though, it can be hinted at by the `systemDependencies` key in `dub.json`/`dub.sdl`. The problem is, I don't think many packages actually use it and I agree that since it's too easy to overlook it, you're often left to figure everything out. It's not something you're likely to find out unless you are already looking for it.

Initializing a class member that is an object
Coming from a more Java-esque background, I'm used to sometimes
initializing class members outside of the constructor :
class MyClass {
Object member = new Object();
}
I've tried using this in D, but I've come to realize it acts very
differently. In Java, the `new Object()` will be executed every
time a new `MyClass` object is instantiated. In D however, it
seems to be executed once, and members of every `MyClass` object
will then be initialized with a reference to that one unique
`Object`.
Example: https://run.dlang.io/is/Qlx2xY
Is this behavior really intentional ? I don't really see how it
could be useful, and it's really confusing at first to see new
objects with weird values even if none of their members has been
touched yet...
