Simple and straightforward code generator for creating C++ code. It also could be used for generating code in any programming language.

Every C++ element could render its current state to a string that could be evaluated as a legal C++ construction. Some elements could be rendered to a pair of representations (C++ classes and functions declaration and implementation)

Usage examples

C++ Variables

Python code:

var_count = Variable(name='count', type='int').val(0)
var_pi = Variable(name='pi', type='float').val(3.14)
var_title = Variable(name='title', type='const char *').val('Title:')
source = Source('main.cpp').add(var_count).add(var_pi).add(var_title)
str(source)

Generated C++ code:

int count = 0;
float pi = 3.14;
const char * title = "Title:";

C++ Functions

Python code:

def factorial_definition():
  return 'return n < 1 ? 1 : (n * factorial(n - 1));'

factorial_function = Function(name='factorial', type='int')
  .arg('int n')
  .impl(factorial_definition)

source = Source('main.cpp').add(factorial_function)
str(source)

Generated C++ code:

int factorial(int n)
{
    return n <= 1 ? 1 : (n * factorial(n - 1));
}

C++ Classes and Structures

Python code:

var_name = Variable(name='name', type='std::string')
fn_getname = Function(name='GetName', type='std::string', qualifiers=['const']).impl('return name;')
fn_setname = Function(name='SetName').arg('std::string & new_name').impl('name = new_name;')

cls_person = Class(name='Person')
  .member(var_name, scope='private')
  .method(fn_getname, scope='public')
  .method(fn_setname, scope='public')

header = Header('Person.h').add(cls_person)
source = Source('Person.cpp').include(header).add(cls_person)
str(header)
str(source)

Generated C++ code for Person.h:

class Person
{
public:
    std::string GetName() const;
    void SetName(std::string & name);
private:
    std::string name;
};

Generated C++ code for Person.cpp:

std::string Person::GetName() const
{
    return name;
}

void Person::SetName(std::string & new_name)
{
    name = new_name;
}
