Re: How to call 'shared static this()' code of a D shared library?
Did you already try rt_init? That should trigger it
How to call 'shared static this()' code of a D shared library?
Simply linking my D shared library with foreign code (Python with the help of ctypes in this case) does not work. What function should I call? What about 'shared static ~this()'? And would the answer be different for 'static this()' etc.? Thank you, Ali

For unittesting individual modules, etc., I can just `dmd -i -unittest -main -run module.d` and it Just Works(tm). It's awesome. Highly recommended.

I think the problem comes from the way you compile and link your
code. I you compile both modules together like this it should
work out:
dmd -ofresult main.d stuff.d
(I'm on the phone, so I can't verify if it works atm)
lambda alias import
stuff.d:
alias doStuff = () {};
main.d:
import stuff;
void main()
{
doStuff();
}

If you really need small images, you could switch to Alpine, but
MUSL c could lead to headaches ;)
There are also the official docker images
https://hub.docker.com/u/dlang2
What is your goal? Do you want to compile s.th. in your docker
image? Then you can have a layered docker file to reduce the size.
Kind regards
