<p class="p3"> * Could I somehow call an external program during compilation which gets the DSL block as input and returns D code?</p>
<p class="p4"><br></p>
<p class="p5">No. But you can pre-process.</p>
<p class="p6"><br></p>
<p class="p7">Yes, sure, but this complicates the build-system. I preferr to use as few parts as possible.</p>
<p class="p6"><br></p>
<p class="p6"><br></p>
<p class="p3"> * Is it possible to populate such a dictonary via CTFE?</p>
<p class="p4"><br></p>
<p class="p5">Sort of, it can be registered, but the actual execution of the registration occurs at runtime.</p>
<p class="p6"><br></p>
<p class="p7">Yes, no problem. How is this done?</p>
<p class="p6"><br></p>
<p class="p5">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 ;).</p>
<p class="p8"><br></p>
<p class="p9">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.</p>
<p class="p10"><br></p>
<p class="p5">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.</p>
<p class="p8"><br></p>
<p class="p9">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.</p>
