I agree with you. Well, dsfml is a very old library. It's a pity 
that the main problem of this topic was caused not because of 
dsfml but something else. In any case, thank you very much for

Hi all,

Im porting some C++ code, which has a mess of a section that 
implements prime number type id's. I've had to smother it to

metaprogramming that D provides is the better solution - Id 
rather not reimplement that C++ mess ideally.


Try something like this:

-snip-
import std;

int[] firstNPrimes(int n) {
// FIXME: replace this with actual primes computation
return [ 2, 3, 5, 7, 11, 13, 17, 19, 23, 29, 31 ];
}

string genEnum(string enumName, idents...)() {
string code = "enum " ~ enumName ~ " {";
auto primes = firstNPrimes(idents.length);
foreach (i, ident; idents) {
code ~= ident ~ " = " ~ primes[i].to!string ~ ", ";
}
code ~= "}";
return code;
}

template PrimeEnum(idents...) {
mixin(genEnum!("PrimeEnum", idents));
}

alias MyEnum = PrimeEnum!(
"unknown", "newline", "identifier", "var", "user_defined",
);

void main() {
writefln("%(%d\n%)", [
MyEnum.unknown,
MyEnum.newline,
MyEnum.identifier,
MyEnum.var,
MyEnum.user_defined
]);
}
-snip-


You can substitute the body of firstNPrimes with any standard 
prime-generation algorithm. As long as it's not too 
heavyweight, you should be able to get it to compile without 
the compiler soaking up unreasonable amounts of memory. :-D  If 
you find the compiler using up too much memory, try 
precomputing the list of primes beforehand and pasting it into 
firstNPrimes (so that the CTFE engine doesn't have to recompute 
it every time you compile).


Note that PrimeEnum can be used to generate any number of enums 
you wish to have prime values.  Or if you replace the call to 
firstNPrimes with something else, you can generate enums whose 
identifiers map to any integer sequence of your choosing.

Hi T,

Thank you for the reply. Im struggling extending this to get the 
nesting working.


I'm trying something like:

string entry(string i, string[] inherit = []) {
return i;
}

alias token_type2 = PrimeEnum!(
entry("unknown"),
entry("newline"),
entry("identifier"),
entry("var", ["identifier"]),
entry("userDefined", ["identifier"])
);

Its worth noting that multiple inherited bases are needed too.

But I can't get those functions contexts linking, can I pass a 
function pointer as lazy into the PrimeEnum!() template?


Would it be easier to just parse the text at once into a single 
templating function?


Kind regards,
Mike Brown

Thanks.


I don't believe that there's any built-in way, as that'd mean 
that functions would have to define what they throw as part of 
their signature (like in Java).


But you can semi-emulate it with metaprogramming, it's just that 
you'll have to manually keep all the information up to date.


Here's an example: https://run.dlang.io/is/UUHumO

Which supports saying what a function directly throws 
(`@Throws`), and also saying what functions it calls that may 
also throw well-defined exceptions (`@ThrowsInclude`), and 
results in `(Exception, MyExcept)`

},
"targetType": "none",
"targetName": "app",
"name": "test"
}

I just want to run it by typing 'dub run'. But the error message 
says that I need to set targetType to none, add targetName and 
dependencies for it.


I have folder source next to dub.json. I'd better show you my 
project structure:


test
|  source
| app.d
|  dub.json

I am using dub 1.23.0 built on Sep 25 2020 on Windows 10 x64. 
Will be very thankful for your help!


Doesn't seem like an installation problem.

Could you post your dub.json contents and describe what you are 
trying to achieve?


Do you have your source files in 'src' or 'source' folder next to 
the dub.json file? If not, you need to tell dub to treat any 
other non conventional folder as source location.
