The reason for Pyste is the built-in code generator of Boost. Python.

Do you have any knowledge about the practical use of Pyste in functions? In fact, Pyste is very similar to SWIG, and relevant source files can be written in C ++-related forms. The following article mainly introduces how Pyste is in Boost. python built-in code generator.

You only need to write the corresponding interface file to generate the corresponding code. Pyste must be installed before it can be used. Go to the Boost installation directory, run the "/libs/python/pyste/install" directory, and run python setup. py install to complete Pyste installation.

Because Pyste requires GCC-XML support, you need to go to the GCC-XML's official website to download the Windows version of GCC-XML. After installing the GCC-XML, you need to add its installation PATH to the system PATH variable. In addition, Pyste also requires support for ElementTree, so you need to download and install it on the relevant official network.

Compile the header file "Num. h" as shown below ".

 
 

  
  
class Num  
  
  
{  
  
  
int value;  
  
  
void set( int n )  
  
  
{  
  
  
value = n;  
  
  
}  
  
  
int get()  
  
  
{  
  
  
return value;  
  
  
}   
  
  
};   
 
 

Write the following interface file "world. pyste ".

 
 

  
  
Class("Num", "Num.h") 
 
 

Due to the file path problem in Windows, it is best to put Pyste in the directory where "Num. h" and "world. pyste" are located. In the Windows command line, enter its directory and run the following command.

 
 

  
  
python pyste.py --module=num world.pyste 
 
 

The "num. cpp" file is generated after running commands for Boost. Python-related code. The content of the file is as follows.

 
 

  
  
// Boost Includes ===================================
===========================  
  
  
#include <boost/python.hpp> 
  
  
#include <boost/cstdint.hpp> 
  
  
// Includes =====================================
===============================  
  
  
#include <Num.h> 
  
  
// Using ======================================
=================================  
  
  
using namespace boost::python;  
  
  
// Module =================================
=====================================  
  
  
BOOST_PYTHON_MODULE(num)  
  
  
{  
  
  
class_< Num >("Num", init< >())  
  
  
.def(init< const Num& >())  
  
  
;  
  
  
}   
 
 

The above is an introduction to the reasons why Pyste is a Boost. Python built-in code generator. I hope you will gain some benefits.
