* Could I somehow call an external program during compilation which
gets the DSL block as input and returns D code?
No. But you can pre-process.
Yes, sure, but this complicates the build-system. I preferr to use as
few parts as possible.
* Is it possible to populate such a dictonary via CTFE?
Sort of, it can be registered, but the actual execution of the
registration occurs at runtime.
Yes, no problem. How is this done?
But you're slightly over thinking this. Write an interpreter and a
parser. The fact that the parser can work at CTFE is irrelevant and
almost a footnote on the page of details ;).
Not really if you think about deployment. I want to create a single
executable, no external files. So I somehow have to get the scripts
included or use the compiler as generator. The main use-case is, that I
want to use a very declarative approach for some UI parts.
If you want to be clever you could generate D code and mix it in based
upon what was parsed. But you'd still want that dictionary.
Yes, mixing in generate D code was the idea. However, I think a good
included infrastructure that support creating DSLs might help a lot to
simplify this.
