First A great thank @alex_dja Before giving comment on you nice answer I have to explain my situation, I am some kind of Dinosaur that had to use Java and Python to help my work. I was in a “learn to code or die” situation. As you can guess, I am coding now. Then I have no bases. I can do things, but I actually don’t understand all the concepts. This is for Java and Python.

For Haxe, I will say I have no rational explanation to explain why this language is so interesting for me. A lot to do with Armory and Blender may be, but that’s an other story. My wish is to use it for work, I am not into game (sadly), then I am trying to transcript all that I have done in Python and Java into Haxe…And may be give it a sexy UI.

Then, and sorry for this long contextual response, but so to say that… I hardly understand your answer. And I will do what that is best to do… I will try to interpret your answer to see If I get it right.

Edit:

Haxe doesn’t have its own runtime.

Runtime definition

This part I have difficulty to grasp.

It mainly just transpiles its source code to a target source or byte code.

Target source like Java or Python Ok…

Bytecode

But take your notice the target runtime can’t be differ from the lib runtime in that case.

I guess that If I use Python libraries, it will not work if my target is Java.

Then, If I understood well, and please redirect me if I am mistaking, you have a project you use say Haxeui and some Python library like Pandas. You export it to Python.

Then…How to do that will be an other question I guess…
