Actually that was were we were going to before Java took over the stage.

IBM also built on those ideas for the 4th release of Visual Age for C++.

Yes. I did come across:

https://github.com/topazproject/topaz

From: "When a Mouse Eats a Python: Smalltalk-style Development for Python and Ruby" https://2017.programming-conference.org/details/MoreVMs-2017...

But it seems abandoned?

I guess maybe maglev ruby on the gemstone platform does move the needle a bit closer:

For Ruby, "pry" gets you at least some of the way there with MRI. It's nowhere near the "full experience", but it has taken a lot of inspiration from Smalltalk, and it's just an entirely different world compared to IRB.

I should clarify; I specifically meant being able to do stuff like write a high level sketch of a module, then simply run it, and implement missing methods and classes as you go. Similar to writing a red/failing test - then filling in functionality.

I suspect a image-like (as in lisp/smalltalk image) view of the code is needed for this to work well (hence the link to "persistent code" for maglev/gemstone).

That said, I do use pry/byebug a lot - but I there might very well be features I'm not aware of.

Oh, there's apparently a repl for clang/c++: "cling"

http://code-ballads.net/read-eval-print-loop-repl-in-c/

https://code-ballads.net/generated-notebooks/cpp/repl_cling/...

There's been some discussion on hn before, but I couldn't find anything particularly recent (or interesting tbh).

Then there is of course rr, as seen recently on hn:

"Instant replay: Debugging C and C++ programs with rr" https://news.ycombinator.com/item?id=27034588

And I also came across "inspector"- which unfortunately appears to be abandoned?
