not sure what you mean by "named substructure, not a nested structure" 
but this works:


struct Outer{
struct Inner{
int x;
int y;
int z;
}
Inner inner;
int a;
}

Outer outer;
outer.a = 7;
outer.inner.y = 42;
//  outer.x = 13; //fails

Depending on your budget, you could also look at Corona - Lua can 
call D easily.


I haven't used on Android, but Qt QML may be worth a look (D 
bindings to QML).



Wrt to D on android I would try porting some existing code and 
see how that goes.  I think stuff seemed to work but because you 
don't yet have so much company then it may be hard to be sure you 
might not hit some problems till you try.

Question about dub and imports

[Jonathan Villa via Digitalmars-d-learn]

I'm trying to build a vibe.d application, but I made a little 
library (just source code) that I want to add to the project.


So, in the generated dub.sdl file I added at the end:
sourcePaths "../D/src"
sourceFiles "../D/src/alfred/package.d"

The problem is at build time DUB tries to create a library file 
and it fails.
I don't want to it to create a .lib file, just "look at this path 
so when I write `import alfred;` you know where this refers to`.


I'm pretty new using the dub thing, I have look in 
https://code.dlang.org/package-format?lang=sdl but I get a little 
confused.


I have already did this in a non-dub project, adding the import 
path with -I and listing the files and it never actually 
generated a lib.


Or is there a way to just inject a direct line to the build 
params like "-I../D/src" alfred/types.d alfred/command.d ...(etc) 
when running dub in my vibe-d project???


(Is really neccesary to look my little source library like a .lib 
file and try to generate it?)

Those two option do different things. My proposal excludes file 
with `main` function from tested sources but keeps actual test 
target (so if you have unittest blocks in other modules, those 
will be checked). Your version completely disabled test target.


I wasn't sure which option you want but glad it helped.

Short answer is it should work: see "Alpha support for mobile" links on
http://dlang.org/download.html

Joakim has been pushing Android support and I've been working on getting
iOS into the core language.  The caveat is that both are alpha support
and it is hard to predict when they will be first class D citizens.

Speaking for the iOS support, the downloadable compiler is based on
2.068 (LDC 0.17.0) and will move to whatever LDC supports after 1.0.0 is
released.  I don't know of any problems at this stage, as long as you
just want to side load your app.  Submitting to the App Store is another
matter.  It has not been done yet and Apple's requirement to include
embedded bitcode is missing currently.

Actually curiously I found another potential use, applying

enum testUDA;
struct T{
 @testUDA
 immutable struct{
 int x;
 int y;
 int z;
 }
}

x,y,and z seem to all be immutable and all have the UDA testUDA. But
even odder, it seems that "struct" in there is doing absolutely nothing.
The same thing can be done with

enum testUDA;
struct T{
 @testUDA
 immutable{
 int x;
 int y;
 int z;
 }
}

So it still seems to be useless other than in the case of unions...


I wonder if it makes a difference for layout. So for example:

struct T
{
   struct
   {
  int x;
  ubyte y;
   }
   ubyte z;
}

If there is padding inserted between y and z.

I might be in the minority opinion here but personally I wouldn't 
use D for enterprise applications in a Fortune 500 type 
environment unless there was a significant order of magnitude 
advantage to doing so (i.e. some niche that D really shines in 
compared to Java/C#). I'd say this for the following reasons:


a. Eco-system. D is a great language but it's eco-system of 
libraries is very weak compared to more mature stacks, 
integration in a heterogeneous enterprise environment is not 
going to be D's forte.


b. Talent availability. Java/C# developers are easy to find, D 
not so much

If you're treating the Android/iOS applications as purely 
"client-side", then there's no reason why you can't create a 
"server-side" application in D using something like vibe.d and 
then passing data between clients and servers using JSON or 
similar data interchange formats. That way,you only develop the 
main server-side application in D, and can communicate with it 
using any other language (Java/C#/Swift) on other operating 
systems and devices.
