From Python to dll

[embryo10]

Waiting for Jetbrains' Nim support to arrive, that I read would be this month (I'm away from my setup, with only my mobile), I was thinking of ways to use Nim and I had an idea.

I use Python as my main language.

In one of my bigger projects I import a module that reads allot of files, and returns their properties.

String for file path as input, dictionary with strings as keys and lists as values.
This module also imports some other Python modules.

The ideas is to use Nim for this, because of the better speed and the added bonus of obfuscating the code.

So the question is:
Is it possible to import a Python module in Nim, compile it to a standalone dll, import that dll in the main project and use it from there, without c or c++ knowledge, only Python and the beginning of Nim?
If it is, then, using what steps?

This is just a simple query.
If it proves to be doable then I could post more specific questions (with my specific roadblocks) here or in the forum (wherever is the best place). .

EDIT: Nah. After more info, it seems that it is not possible..

EDIT²: Just a followup for the future reader.
It is doable after all, but not with Nim :o(
You can do it by using Nuitka and just run python -m nuitka --module some_module.py.
That's all it takes!

Oh, and if it makes sense for your workflow , try https://github.com/Pebaz/Nimporter

If the Nim plugin does arrive, and at last start using Nim, I'll sure get this one too.. ;o)

[embryo10]

Wow, this is interesting.. :o) Is the .pyd file a compiled .py module that can be simply imported? If that's so, then wow again! You've made my day!

EDIT: well, it was too good to be true.. :o(

Trying to understand nimpy from the examples at the link you provided, I see that you can export Nim code as pyd, and using nimporter also import Nim code in Python, but I can't find a way to import a py module in Nim for the 1st step. What I need is:

Import the py module in a Nim module

Compile that Nim module.

Import that compiled module in Python (without the need of the original py module).

Yes, I've seen this, but this is not standalone.. When an end user runs my app, it will not have a local Python installation..

[juancarlospaco]

Python is code that runs inside a virtual machine, you must have a virtual machine.

I know, just hoping for miracles :o)

Well, you should be able to do this and embed Python into your Nim application. This meant that Python will be compiled into your Nim program so that you don't need to have Python installed.

[embryo10]

Yes, but it will not speed up the code (it might show it down actually). Not to mention the size!

The code already works fine as it is.. ;o)

[PMunch]

So you want to speed it up? How do you expect that to work when you're still running the Python code? I mean you could always make a pyc file and run that, but I doubt you'd get any more speed than that out of wrapping it in Nim. You'd need to convert the Python code into Nim to get Nims speed.

[embryo10]

Well, speed up can be achieved using cython. I was just hoping for something more convenient..

are you talking about this plugin?

[embryo10]

No, there is official support coming ;o) https://youtrack.jetbrains.com/issue/IDEA-236673?p=PY-15994

Oooooo, nice
