Subject: [PATCH] lisp/ob-C.el: Support dub dependencies for dlang
Dlangs official package manager dub (https://dub.pm/) supports running
single files that carry dependency information in a /+ dub.sdl comment
block.
This patch switches from rdmd to dub if dependencies are used in the
source block. The dependency format used in the sourceblocks is
`:dependencies '(dep1=v1 ...)`.
The version specifier can be left out or be used with `*` which then
resolves to the latest version of the package.
Example:
#+begin_src D :dependencies '(mir-algorithm=*)
import mir.combinatorics;
import mir.ndslice.fuse;
foreach (permutation; ['a', 'b', 'c'].permutations) {
writeln(permutation);
}
#+end_src
