Hi Mariano, Would be good to have you, there's a lot to learn from your work ;-) Michal's full name is Michal Balda and honestly I have no idea yet if and how we'll learn more about his framework. I just know he's working on several very interesting things. If you ask: will there be any reco

I would not hold my breath if I were you for 3 reasons 1) this idea will go through only if my direct bridge via shared memory between Pharo and Unreal fails are is proven very limited, which I highly doubt. 2) even if I proceed with it, I will certainly be specialised for Unreal and have little

So this isn't a specific out-of-the-box solution to any of the code-generation use cases people have been discussing, but I thought it was relevant enough to toss it out there. I'm currently doing some work on program synthesis using a Pharo port of the miniKanren logic programming language (http:

My personal feeling on code generators is they are a bad code smell and the desire to use them tends to imply that your programming language isn't dynamic enough. That said I have used DNE on proto object proxies to capture messages sent and generate handlers (I have used this on Morphic to try

Re: [Pharo-users] CodeGenerator, your opinions?

Hi Dimitris, That would be certainly nice. C++ is hard, but if one start with a basic instantiation template it could be easier to move forward to more complex tasks like mapping data structures to STL, their containers and iterators. And I think it would attract C++ developers to Smalltalk. Cheer

There is the CCodeGenerator , which is basically Slang, Smalltalk that is turned into basic C. I would like to expand it to generate C++ at some point for converting pharo code to C++ code that I will be able to add to Unreal. Though its a very low priority project for me. http://smalltalkhub.com/

Re: [Pharo-users] Cog VM on Raspberry Pi ?

The VM you use is the fastest one available. It's slower mostly due to non Smalltalk concerns (processor architecture, energy consumption, frequency, overall hardware). There is an abstraction over the back-ends in the JIT and it could be that overall the JIT is a little bit more optimised for in
