Thread: Generate python code out of C++

I would like to know if anyone of you knows about a library which is able to generate python code. Would that maybe be possible with boost.python?

If there is nothing like that, could you point me to the direction how I could do it myself?

best regards

Boost.Python is intended to execute C++ code from Python and vice versa. Did you try googling for a C++ to Python translator?

Perhaps a bit of clarification is in order.

Do you want to convert C++ code to Python?
Do you want your C++ program to generate unrelated Python code for some purpose and possibly execute it?

Have you learned how to read/write files? It's relatively easy to print text to a file and save it with a particular file name.

A basic example:

Code:

#include <iostream>
#include <fstream>

int main()
{
  std::ofstream pythonFile("test.py");

  pythonFile << "print 'Hello, World!'" << std::endl;
  pythonFile << "for x in range(10):" << std::endl;
  pythonFile << "    print 'x: ', x" << std::endl;

  return 0;
}

I already know I could do it like that, but python is pretty strict on format, it would be so much work to write every line into a file, maybe I have to think about a function that generates the python functions dynamically.

Is there a possibility in C++ to lets say have a template file with placeholders and then replace them?

Edit:

Or maybe it would be easier to provide a interface to python and pass the parsed values to a python script which generates the rest...

Then you could create a tree hierarchy that automatically formats itself properly when you dump it to the file.

If it was my project, I would create a class called "Scope." The constructor for Scope would take, as its parameter, the opening statement (for, if, etc.). Scope would contain a list of statements and child scopes (hint: they can be derived from a common base class), and functions to add and optionally remove statements and child scopes. I would then use recursion to walk down the tree when dumping it to a file. You can make it as simple or as complex as you want it to be.
