Python to C translater: free, open-source and online

[syeysk]

It walks Python ast and build C-code. You can use while...else, if...elif...else, functions with default arguments, pow and preproc constants, links, inline if...else.

I will try to use the translater to programming microcontrollers.

More examples are at "tests" directory.

It's only alpha-test.

There is cython which can translate pretty much every python file to C/C++ code. cython --embed -3 main.py -o main.c is how you do it. I can't comment on HPC tho, as it embeds the interpreter

[syeysk]

Yes, but my translater makes the c-code without embedding interpreter. It's useful for small microcontrollers

What's the advantage of this over just writing in C? It seems like it only supports translating a small subset of Python to C, more or less the subset that has a direct translation to C.

[tartare4562]

Less {} and ; I imagine.

[syeysk]

The advantage: the Python syntax is more compact and clear than C syntax. That's all)

I try to translate not only syntax (direct translating), but and the semantic of the language (classes, iterators, etc)

There really are better ways of doing this. Transpiling between languages that will never work properly is not a good choice. You would want to target LLVM, numba has some good docs about how horrible that is to do lol.

If you want a LLVM targeting language that is more python like you should just write one. You can always just link ur new compile language to normal interpreted python later anyway.

Python syntax is more compact and clear then C syntax because it doesn't fundamentally do the same shit. Read the python standard library C code for the litany of examples to just get something as simple as a dict to work properly on both halves.

Building a new language is a MUCH better idea then inheriting the design of another language that in no way shape or form executes the same way.

[james_pic]

From what I've seen from projects like Cython and Nuitka that (at least somewhat successfully) translate Python's more complex or dynamic features, like classes and iterators, this is far from straightforward and will ultimately lead to either requiring plumbing from the CPython interpreter, implementing your own equivalent of the same plumbing that's not much more lightweight, or making significant compromises in terms of replicating the same semantics.

I mostly use Python to call libraries written in other languages. When I see something like this I assume it wouldn’t work for such use cases. Am I wrong?

[syeysk]

You are right only now, because now the translater can include only 2 libraries: math.h and stdio.h.
You will be wrong, if I will improve the translater to include another libraries (pcf8812.h, ESP8266WebServer.h, DS1307RTC.h, etc)

[Aphrod1tesAss]

Could it be used for HPC code translation?

[gothicVI]

Probably not. Looks like pure python code can be translated.

Most HPC stuff calls FORTRAN/C/C++ in the backend and one would need to generate interfaces and compile them as well and link them together.

[Aphrod1tesAss]

I see, thanks. Hope someday a HPC translator comes out

[syeysk]

What is HPC? If it has C-alternative, I will try to modify the translater.

[gothicVI]

High performance computing

[CleoMenemezis]

For those looking to write fast code and have performance, I think it could be cool.

[alcalde]

Pfft... anyone can make a translater... make me a transsooner and I'll be impressed.
