> You keep repeating the line that D is far more interoperable than Nim. Did you miss my reply below? Or did you simply not believe me and downvote it? I did not downvote anyone unless it was an accident :) > Nim is superior to D in terms of interoperability with C, C++, and Objective C because Nim can compile to either of those languages. I did not try myself. Well, I did not try Nim to the level I tried D, starting bc I know C++ better than D, though I also know quite a bit of Python (my "second" language). I have a question, though, about interoperability: you can output Nim code to C++, and mix it. Fair point. But that would be useful to integrate my Nim code into C++ (C++ being the "driver" app). What about the other direction where I can consume C++ from Nim? I have no idea and I ask this question with the best of the intentions :) You thought very bad about me and the downvotes before.

I have no idea and I ask this question with the best of the intentions :) I was actually talking about it from that direction, i.e. using C++ libraries in Nim. You can wrap pretty much any C++ feature in Nim: destructors, namespaces, you name it. Because Nim compiles to C++ it can interface with it incredibly well. Happy to answer any more questions in case I'm not clear. > You thought very bad about me and the downvotes before. Apologies. I just saw you reiterating the line I challenged without replying to me and was wondering what happened. Was just asking, not blaming :)

  Yes, I am genuinely interested. So I am going to ask a bit more. I am open to new and better tools :) > I was actually talking about it from that direction, i.e. using C++ libraries in Nim. You can wrap pretty much any C++ feature in Nim: destructors, namespaces, you name it. Is there any documentation about how to wrap my C++ code into Nim? I do get I can generate C++ from Nim, but I am not sure how it would look to use C++ from Nim. In D for me it is quite clear (with extern (C++) and there is a clear mapping for interfaces and other things. I do not need anything spectacularly fancy, just smooth. Y' know, I am a person who likes to finish things without getting too lost on the details. You also mentioned many people consider Nim "production-ready". My question here is, if I start to try it, how many breakages can I expect? 4-5, in the tens? Until version 1.0 I mean. And my last question: how does it compare to D if I have to: - use a well-mantained GUI library in at least one system (multiplatform would be a big plus) - how mature is the standard (and other libraries also if that is easy to add) library for: json handling, binary serialization, algorithmic code (a la range-v3 or ranges in D. Something along the lines of python iterators, functools, comprehensions and itertools also ok). - would I be able to use Nim in embedded if I do a port of some software? Namely, would I be able to remove the GC? One thing that worries me is that I am much more familiar with metaprogramming in C++ and D's metaprogramming is much closer than Nim's I guess. If you could refer me to good (as in up-to-date) Nim style I would highly appreciate it, specially in the areas of how to manage runtime polymorphism and metaprogramming with an eye on generative programming (basically I want to generate a bunch of things from 3 or 4 basic building blocks in arbitrary combinations). Thanks for your time! > Apologies. I just saw you reiterating the line I challenged without replying to me and was wondering what happened. Was just asking, not blaming :) No problem, I just did not mean to make anyone offended :)

Until version 1.0 I mean. Depends which features you are using. The newer features (concepts for example) will likely have more breakages than the rest of the language. We already have a lot of code written in Nim and a book published (which we are committed to keep compatible with 1.0) so breakages should be minimal (unforeseen circumstances of course may happen). > how does it compare to D if I have to: > > - use a well-mantained GUI library in at least one system (multiplatform would be a big plus) I'm not sure about the status of GUI support for D.

      I must say that, even if unfamiliar to me, I am quite impressed about the C++ interoperability :)
