- Right now, the only supported configuration is one in which the py_cpp - source files are statically linked with the source for your extension - module. You may first build them into a library and link it with your - extension module source, but the effect is the same as compiling all - the source files together. Some users have successfully built the - py_cpp sources into a shared library, and support for a shared library - build is planned, but not yet implemented. The py_cpp source files are: -

CXX

-

- Like py_cpp, CXX attempts to - provide a C++-oriented interface to Python. In most cases, like py_cpp, - it relieves the user from worrying about reference-counts. As far as I - can tell, there is no support for subclassing C++ extension types in - Python. An even more-significant difference is that a user's C++ code is - still basically “dealing with Python objects”, though they are wrapped - in C++ classes. This means such jobs as argument parsing and conversion - are still left to be done explicitly by the user. - -

- CXX claims to interoperate well with the C++ Standard Library - (a.k.a. STL) by providing iterators into Python Lists and Dictionaries, - but the claim is unfortunately unsupportable. The problem is that in - general, access to Python sequence and mapping elements through - iterators requires the use of proxy objects as the return value of - iterator dereference operations. This usage conflicts with the basic - ForwardIterator requirements in - section 24.1.3 of the standard (dereferencing must produce a - reference). Although you may be able to use these iterators with some - operations in some standard library implementations, it is neither - guaranteed to work nor portable. - -

- As far as I can tell, CXX enables one to write what is essentially - idiomatic Python code in C++, manipulating Python objects through the - same fully-generic interfaces we use in Python. I think it would be fair - to say that while you're not programming directly to the “bare - metal” with CXX, in comparison to py_cpp, it presents a low-level - interface to Python. That use is also supported by the py_cpp object - wrappers. - -

- Paul F. Dubois, the original - author of CXX, has told me that what I've described is only half of the - picture with CXX, but I never understood his explanation well-enough to - fill in the other half. Here is his response to the commentary above: - -

-“My intention with CXX was not to do what you are doing. It was to enable a -person to write an extension directly in C++ rather than C. I figured others had -the wrapping business covered. I thought maybe CXX would provide an easier -target language for those making wrappers, but I never explored -that.”
-Paul Dubois -

SWIG

-

- SWIG is an impressively mature tool - for exporting an existing ANSI 'C' interface into various scripting - languages. Swig relies on a parser to read your source code and produce - additional source code files which can be compiled into a Python (or - Perl or Tcl) extension module. It has been successfully used to create - many Python extension modules. Like py_cpp, SWIG is trying to allow an - existing interface to be wrapped with little or no change to the - existing code. The documentation says “SWIG parses a form of ANSI C - syntax that has been extended with a number of special directives. As a - result, interfaces are usually built by grabbing a header file and - tweaking it a little bit.” For C++ interfaces, the tweaking has often - proven to amount to more than just a little bit. One user - writes: - -

“The problem with swig (when I used it) is that it - couldnt handle templates, didnt do func overloading properly etc. For - ANSI C libraries this was fine. But for usual C++ code this was a - problem. Simple things work. But for anything very complicated (or - realistic), one had to write code by hand. I believe py_cpp doesn't have - this problem[sic]... IMHO overloaded functions are very important to - wrap correctly.”
-Prabhu Ramachandran -
- -

- By contrast, py_cpp doesn't attempt to parse C++ - the problem is simply - too complex to do correctly. Technically, one does - write code by hand to use py_cpp. The goal, however, has been to make - that code nearly as simple as listing the names of the classes and - member functions you want to expose in Python. - -

SIP

-

- SIP - is a system similar to SWIG, though seemingly more - C++-oriented. The author says that like py_cpp, SIP supports overriding - extension class member functions in Python subclasses. It appears to - have been designed specifically to directly support some features of - PyQt/PyKDE, which is its primary client. Documentation is almost - entirely missing at the time of this writing, so a detailed comparison - is difficult. - -

ILU

-

- ILU - is a very ambitious project which tries to describe a module's interface - (types and functions) in terms of an Interface - Specification Language (ISL) so that it can be uniformly interfaced - to a wide range of computer languages, including Common Lisp, C++, C, - Modula-3, and Python. ILU can parse the ISL to generate a C++ language - header file describing the interface, of which the user is expected to - provide an implementation. Unlike py_cpp, this means that the system - imposes implementation details on your C++ code at the deepest level. It - is worth noting that some of the C++ names generated by ILU are supposed - to be reserved to the C++ implementation. It is unclear from the - documentation whether ILU supports overriding C++ virtual functions in Python. - -

GRAD

-

- GRAD - is another very ambitious project aimed at generating Python wrappers for - interfaces written in “legacy languages”, among which C++ is the first one - implemented. Like SWIG, it aims to parse source code and automatically - generate wrappers, though it appears to take a more sophisticated approach - to parsing in general and C++ in particular, so it should do a much better - job with C++. It appears to support function overloading. The - documentation is missing a lot of information I'd like to see, so it is - difficult to give an accurate and fair assessment. I am left with the - following questions: -

-

- Anyone in the possession of the answers to these questions will earn my - gratitude for a write-up ;-) - -

Zope ExtensionClasses

-

- - ExtensionClasses in Zope use the same underlying mechanism as py_cpp - to support subclassing of extension types in Python, including - multiple-inheritance. Both systems support pickling/unpickling of - extension class instances in very similar ways. Both systems rely on the - same “Don - Beaudry Hack” that also inspired Don's MESS System. -

- The major differences are: -

- c++boost.gif (8819 bytes)Wrapping enums -

-

Because there is in general no way to deduce that a value of arbitrary type T -is an enumeration constant, py_cpp cannot automatically convert enum values to -and from Python. To handle this case, you need to decide how you want the enum -to show up in Python (since Python doesn't have enums). Once you have done that, -you can write some simple from_python() and -to_python() functions. - -

If you are satisfied with a Python int as a way to represent your enum -values, py_cpp provides a shorthand for these functions. You just need to -instantiate boost::python::enum_as_int_converters<EnumType> where -EnumType is your enumerated type. There are two convenient ways to do this: - -

    -
  1. -
    -// drop into namespace python and explicitly instantiate
-BOOST_PYTHON_BEGIN_CONVERSION_NAMESPACE // this is a gcc 2.95.2 bug workaround
-  template class enum_as_int_converters;
-BOOST_PYTHON_END_CONVERSION_NAMESPACE
-
    -
    -
  2. -// instantiate as base class in any namespace
-struct EnumTypeConverters
-    : boost::python::py_enum_as_int_converters
-{
-};
-
    -
- -

Either of the above is equivalent to the following declarations: -

-BOOST_PYTHON_BEGIN_CONVERSION_NAMESPACE // this is a gcc 2.95.2 bug workaround
-
-  MyEnumType from_python(PyObject* x, boost::python::type<MyEnumType>)
-  {
-      return static_cast<MyEnum>(
-        from_python(x, boost::python::type<long>()));
-  }
-
-  MyEnumType from_python(PyObject* x, boost::python::type<const MyEnumType&>)
-  {
-      return static_cast<MyEnum>(
-        from_python(x, boost::python::type<long>()));
-  }
-
-  PyObject* to_python(MyEnumType x)
-  {
-      return to_python(static_cast<long>(x));
-  }
-BOOST_PYTHON_END_CONVERSION_NAMESPACE
-
- -

This technique defines the conversions of -MyEnumType in terms of the conversions for the built-in - long type. - -You may also want to add a bunch of lines like this to your module -initialization: - -

-mymodule.add(boost::python::to_python(enum_value_1), "enum_value_1");
-mymodule.add(boost::python::to_python(enum_value_2), "enum_value_2");
-...
-
- -You can also add these to an extension class definition, if your enum happens to -be local to a class and you want the analogous interface in Python: - -
-my_class.add(boost::python::to_python(enum_value_1), "enum_value_1");
-my_class.add(boost::python::to_python(enum_value_2), "enum_value_2");
-...

- A Simple Example Using py_cpp -

-

- Suppose we have the following C++ API which we want to expose in - Python: -

-
-#include <string>
-
-namespace hello {
-  class world
-  {
-   public:
-      world(int);
-      ~world();
-      std::string get() const { return "hi, world"; }
-    ...
-  };
-  std::size_t length(const world& x) { return std::strlen(x.get()); }
-}
-
-
-
-

- Here is the C++ code for a python module called hello - which exposes the API using py_cpp: -

-
-#include 
-// Python requires an exported function called init<module-name> in every
-// extension module. This is where we build the module contents.
-extern "C"
-#ifdef _WIN32
-__declspec(dllexport)
-#endif
-void inithello()
-{
-    try
-    {
-       // create an object representing this extension module
-       boost::python::module_builder hello("hello");
-       // Create the Python type object for our extension class
-       boost::python::class_builder<hello::world> world_class(hello, "world");
-       // Add the __init__ function
-       world_class.def(boost::python::constructor<int>());
-       // Add a regular member function
-       world_class.def(&hello::world::get, "get");
-       // Add a regular function to the module
-       hello.def(hello::length, "length");
-    }
-    catch(...)
-    {
-       boost::python::handle_exception();    // Deal with the exception for Python
-    }
-}
-// Win32 DLL boilerplate
-#if defined(_WIN32)
-#include <windows.h>
-extern "C" BOOL WINAPI DllMain(HINSTANCE, DWORD, LPVOID)
-{
-    return 1;
-}
-#endif // _WIN32
-
-
-

- That's it! If we build this shared library and put it on our - PYTHONPATH we can now access our C++ class and function from - Python. -

-
->>> import hello
->>> hi_world = hello.world(3)
->>> hi_world.get()
-'hi, world'
->>> hello.length(hi_world)
-9
-
-
-

- We can even make a subclass of hello.world: -

-
->>> class my_subclass(hello.world):
-...     def get(self):
-...         return 'hello, world'
-...
->>> y = my_subclass(4)
->>> y.get()
-'hello, world'
-
-
-

- Pretty cool! You can't do that with an ordinary Python extension type! -

-
->>> hello.length(y)
-9
-
-
-

- Of course, you may now have a slightly empty feeling in the pit of - your little pythonic stomach. Perhaps you feel your subclass deserves - to have a length() of 12? If so, read on... -

- A Brief Introduction to writing Python extension modules -

-

- Interfacing any language to Python involves building a module which can - be loaded by the Python interpreter, but which isn't written in Python. - This is known as an extension module. Many of the built-in Python - libraries are constructed in 'C' this way; Python even supplies its - fundamental - types using the same mechanism. An extension module can be statically - linked with the Python interpreter, but it more commonly resides in a - shared library or DLL. -

- As you can see from The Python Extending - and Embedding Tutorial, writing an extension module normally means - worrying about -

- This last item typically occupies a great deal of code in an extension - module. Remember that Python is a completely dynamic language. A callable - object receives its arguments in a tuple; it is up to that object to - extract those arguments from the tuple, check their types, and raise - appropriate exceptions. There are numerous other tedious details that need - to be managed; too many to mention here. Py_cpp is designed to lift most of - that burden.
-
- -

- Another obstacle that most people run into eventually when extending - Python is that there's no way to make a true Python class in an extension - module. The typical solution is to create a new Python type in the - extension module, and then write an additional module in 100% Python. The - Python module defines a Python class which dispatches to an instance of - the extension type, which it contains. This allows users to write - subclasses of the class in the Python module, almost as though they were - sublcassing the extension type. Aside from being tedious, it's not really - the same as having a true class, because there's no way for the user to - override a method of the extension type which is called from the - extension module. Py_cpp solves this problem by taking advantage of Python's metaclass - feature to provide objects which look, walk, and hiss almost exactly - like regular Python classes. Py_cpp classes are actually cleaner than - Python classes in some subtle ways; a more detailed discussion will - follow (someday).

Inheritance in Python

- -

- Py_cpp extension classes support single and multiple-inheritance in - Python, just like regular Python classes. You can mix built-in Python - classes with py_cpp extension classes in a derived class' tuple of - bases. Whenever a py_cpp extension class is among the bases for a new - class in Python, the result is an extension class: -

-
->>> class MyPythonClass:
-...     def f(): return 'MyPythonClass.f()'
-...
->>> import my_extension_module
->>> class Derived(my_extension_module.MyExtensionClass, MyPythonClass):
-...     '''This is an extension class'''
-...     pass
-...
->>> x = Derived()
->>> x.f()
-'MyPythonClass.f()'
->>> x.g()
-'MyExtensionClass.g()'
-
-
- -

Reflecting C++ Inheritance Relationships

-

- Py_cpp also allows us to represent C++ inheritance relationships so that - wrapped derived classes may be passed where values, pointers, or - references to a base class are expected as arguments. The - declare_base member function of - class_builder<> is used to establish the relationship - between base and derived classes: - -

-
-#include <memory> // for std::auto_ptr<>
-
-struct Base {
-    virtual ~Base() {}
-    virtual const char* name() const { return "Base"; }
-};
-
-struct Derived : Base {
-    Derived() : x(-1) {}
-    virtual const char* name() const { return "Derived"; }
-    int x;
-};
-
-std::auto_ptr<Base> derived_as_base() {
-    return std::auto_ptr<Base>(new Derived);
-}
-
-const char* get_name(const Base& b) {
-    return b.name();
-}
-
-int get_derived_x(const Derived& d) {
-    return d.x;
-}
-    

-#include 
-extern "C"
-#ifdef _WIN32
-__declspec(dllexport)
-#endif
-void initmy_module()
-{
-    try
-    {
-       boost::python::module_builder my_module("my_module");
-
-       boost::python::class_builder<Base> base_class(my_module, "Base");
-       base_class.def(boost::python::constructor<void>());
-
-       boost::python::class_builder<Derived> derived_class(my_module, "Derived");
-       derived_class.def(boost::python::constructor<void>());
-       // Establish the inheritance relationship between Base and Derived
-       derived_class.declare_base(base_class);
-
-       my_module.def(derived_as_base, "derived_as_base");
-       my_module.def(get_name, "get_name");
-       my_module.def(get_derived_x, "get_derived_x");
-    }
-    catch(...)
-    {
-       boost::python::handle_exception();    // Deal with the exception for Python
-    }
-}
-
-
- -

- Then, in Python: -

-
->>> from my_module import *
->>> base = Base()
->>> derived = Derived()
->>> get_name(base)
-'Base'
-
objects of wrapped class Derived may be passed where Base is expected
->>> get_name(derived) 
-'Derived'
-
objects of wrapped class Derived can be passed where Derived is -expected but where type information has been lost.
->>> get_derived_x(derived_as_base()) 
--1
-
-
- -

Inheritance Without Virtual Functions

- -

- If for some reason your base class has no virtual functions but you still want - to represent the inheritance relationship between base and derived classes, - pass the special symbol boost::python::without_downcast as the 2nd parameter - to declare_base: - -

-
-struct Base2 {};
-struct Derived2 { int f(); };
-

-   ...
-   boost::python::class_builder<Base> base2_class(my_module, "Base2");
-   base2_class.def(boost::python::constructor<void>());
-
-   boost::python::class_builder<Derived2> derived2_class(my_module, "Derived2");
-   derived2_class.def(boost::python::constructor<void>());
-   derived_class.declare_base(base_class, boost::python::without_downcast);
-
-
- -

This approach will allow Derived2 objects to be passed where - Base2 is expected, but does not attempt to implicitly convert (downcast) - smart-pointers to Base2 into Derived2 pointers, - references, or values. - -

An Example

-

- To expose overloaded functions in Python, simply def() each - one with the same Python name: -

-
-inline int f1() { return 3; }
-inline int f2(int x) { return x + 1; }
-
-class X {
-public:
-    X() : m_value(0) {}
-    X(int n) : m_value(n) {}
-    int value() const { return m_value; }
-    void value(int v) { m_value = v; }
-private:
-    int m_value;
-};
-  ...
-
-void initoverload_demo()
-{
-    try
-    {
-        boost::python::module_builder overload_demo("overload_demo");
-        // Overloaded functions at module scope
-        overload_demo.def(f1, "f");
-        overload_demo.def(f2, "f");
-
-        boost::python::class_builder<X> x_class(overload_demo, "X");
-        // Overloaded constructors
-        x_class.def(boost::python::constructor<>());
-        x_class.def(boost::python::constructor<int>());
-
-        // Overloaded member functions
-        x_class.def((int (X::*)() const)&X::value, "value");
-        x_class.def((void (X::*)(int))&X::value, "value");
-  ...
-
-
- -

- Now in Python: -

-
->>> from overload_demo import *
->>> x0 = X()
->>> x1 = X(1)
->>> x0.value()
-0
->>> x1.value()
-1
->>> x0.value(3)
->>> x0.value()
-3
->>> X('hello')
-TypeError: No overloaded functions match (X, string). Candidates are:
-void (*)()
-void (*)(int)
->>> f()
-3
->>> f(4)
-5
-
-
- -

Discussion

-

- Notice that overloading in the Python module was produced three ways:

    -
  1. by combining the non-overloaded C++ functions int f1() - and int f2(int) and exposing them as f in Python. -
  2. by exposing the overloaded constructors of class X -
  3. by exposing the overloaded member functions X::value. -
-

- Techniques 1. and 3. above are really alternatives. In case 3, you need - to form a pointer to each of the overloaded functions. The casting - syntax shown above is one way to do that in C++. Case 1 does not require - complicated-looking casts, but may not be viable if you can't change - your C++ interface. N.B. There's really nothing unsafe about casting an - overloaded (member) function address this way: the compiler won't let - you write it at all unless you get it right. - -

An Alternative to Casting

-

- This approach is not neccessarily better, but may be preferable for some - people who have trouble writing out the types of (member) function - pointers or simply prefer to avoid all casts as a matter of principle: -

-
-// Forwarding functions for X::value
-inline void set_x_value(X& self, int v) { self.value(v); }
-inline int get_x_value(X& self) { return self.value(); }
-   ...
-        // Overloaded member functions
-        x_class.def(set_x_value, "value");
-        x_class.def(get_x_value, "value");
-
-
-

Here we are taking advantage of the ability to expose C++ functions at -namespace scope as Python member functions. - -

Overload Resolution

- The function overload resolution mechanism in py_cpp works as - follows: - -

Overridable Virtual Functions

- -

- In the previous example we exposed a simple - C++ class in Python and showed that we could write a subclass. We even - redefined one of the functions in our derived class. Now we will learn - how to make the function behave virtually when called from C++. - - -

Example

- -

In this example, it is assumed that world::get() is a virtual -member function: - -

-class world
-{
- public:
-    world(int);
-    virtual ~world();
-    virtual std::string get() const { return "hi, world"; }
-};
-
- -

- We'll need a derived class* to help us - dispatch the call to Python. In our derived class, we need the following - elements: - -

    - -
  1. A PyObject* data member that holds a - reference to the corresponding Python object. - -
  2. A constructor for each exposed constructor of the - base class which stores an additional initial PyObject* argument - in the data member described above. - -
  3. An implementation of each virtual function you may - wish to override in Python which uses - boost::python::callback<return-type>::call_method() to call - the Python override. - -
  4. For each non-pure virtual function meant to be - overridable from Python, a static member function (or a free function) taking - a reference or pointer to the base type as the first parameter and which - forwards any additional parameters neccessary to the default - implementation of the virtual function. See also this - note if the base class virtual function is private. - -
- -
-struct world_callback : world
-{
-    world_callback(PyObject* self, int x) // 2
-        : world(x),
-          m_self(self) {}
-
-    std::string get() const // 3
-        { return boost::python::callback<std::string>::call_method(m_self, "get"); }
-
-    static std::string default_get(const hello::world& self) const // 4
-        { return self.world::get(); }
- private:
-    PyObject* m_self; // 1
-};
-
- -

- Finally, we add world_callback to the - class_builder<> declaration in our module initialization - function, and when we define the function, we must tell py_cpp about the default - implementation: - -

-// Create the Python type object for our extension class
-boost::python::class_builder<hello::world,world_callback> world_class(hello, "world");
-// Add a virtual member function
-world_class.def(&world::get, "get", &world_callback::default_get);
-
- -

- Now our subclass of hello.world behaves as expected: - -

->>> class my_subclass(hello.world):
-...     def get(self):
-...         return 'hello, world'
-...
->>> hello.length(my_subclass())
-12
-
- -

- *You may ask, "Why do we need this derived - class? This could have been designed so that everything gets done right - inside of hello::world." One of the goals of py_cpp is to be - minimally intrusive on an existing C++ design. In principle, it should be - possible to expose the interface for a 3rd party library without changing - it. To unintrusively hook into the virtual functions so that a Python - override may be called, we must use a derived class. - -

Pure Virtual Functions

- -

- A pure virtual function with no implementation is actually a lot easier to - deal with than a virtual function with a default implementation. First of - all, you obviously don't need to supply - a default implementation. Secondly, you don't need to call - def() on the extension_class<> instance - for the virtual function. In fact, you wouldn't want to: if the - corresponding attribute on the Python class stays undefined, you'll get an - AttributeError in Python when you try to call the function, - indicating that it should have been implemented. For example: -

-
-struct baz {
-    virtual int pure(int) = 0;
-};
-
-struct baz_callback {
-    int pure(int x) { boost::python::callback<int>::call_method(m_self, "pure", x); }
-};
-
-extern "C"
-#ifdef _WIN32
-__declspec(dllexport)
-#endif
-initfoobar()
-{
-    try
-    {
-       boost::python::module_builder foobar("foobar");
-       boost::python::class_builder<baz,baz_callback> baz_class("baz");
-       baz_class.def(&baz::pure, "pure");
-    }
-    catch(...)
-    {
-       boost::python::handle_exception();    // Deal with the exception for Python
-    }
-}
-
-
-

- Now in Python: -

-
->>> from foobar import baz
->>> x = baz()
->>> x.pure(1)
-Traceback (innermost last):
-  File "<stdin>", line 1, in ?
-AttributeError: pure
->>> class mumble(baz):
-...    def pure(self, x): return x + 1
-...
->>> y = mumble()
->>> y.pure(99)
-100
-
- -

Private Non-Pure Virtual Functions

 - -

This is one area where some minor intrusiveness on the wrapped library is -required. Once it has been overridden, the only way to call the base class -implementation of a private virtual function is to make the derived class a -friend of the base class. You didn't hear it from me, but most C++ -implementations will allow you to change the declaration of the base class in -this limited way without breaking binary compatibility (though it will certainly -break the ODR). - -

The Problem With Pointers

- -

-In general, raw pointers passed to or returned from functions are problematic -for py_cpp because pointers have too many potential meanings. Is it an iterator? -A pointer to a single element? An array? When used as a return value, is the -caller expected to manage (delete) the pointed-to object or is the pointer -really just a reference? If the latter, what happens to Python references to the -referent when some C++ code deletes it? -

-There are a few cases in which pointers are converted automatically: -

- -

Can you avoid the problem?

- -

My first piece of advice to anyone with a case not covered above is -“find a way to avoid the problem.” For example, if you have just one -or two functions returning a pointer to a single (not an array of) const -T* for some wrapped T, you may be able to write a “thin -converting wrapper” over those two functions as follows (Since py_cpp -converts const T& values to_python by copying the T -into a new extension instance, Foo must have a public copy constructor): - -

-const Foo* f(); // original function
-const Foo& f_wrapper() { return *f(); }
-  ...
-my_module.def(f_wrapper, "f");
-
- -

Dealing with the problem

- -

The first step in handling the remaining cases is to figure out what the pointer -means. Several potential solutions are provided in the examples that follow: - -

Returning a pointer to a wrapped type

- -

Returning a const pointer

- -

If you have lots of functions returning a const T* for some -wrapped T, you may want to provide an automatic -to_python conversion function so you don't have to write lots of -thin wrappers. You can do this simply as follows: - -

-BOOST_PYTHON_BEGIN_CONVERSION_NAMESPACE // this is a gcc 2.95.2 bug workaround
-  PyObject* to_python(const Foo* p) {
-     return to_python(*p); // convert const Foo* in terms of const Foo&
-  }
-BOOST_PYTHON_END_CONVERSION_NAMESPACE
-
- -

If you can't (afford to) copy the referent, or the pointer is non-const

- -

If the wrapped type doesn't have a public copy constructor, if copying is -extremely costly (remember, we're dealing with Python here), or if the -pointer is non-const and you really need to be able to modify the referent from -Python, you can use the following dangerous trick. Why dangerous? Because python -can not control the lifetime of the referent, so it may be destroyed by your C++ -code before the last Python reference to it disappears: - -

-BOOST_PYTHON_BEGIN_CONVERSION_NAMESPACE // this is a gcc 2.95.2 bug workaround
-  PyObject* to_python(Foo* p)
-  {
-      return boost::python::PyExtensionClassConverters::ptr_to_python(p);
-  }
-
-  PyObject* to_python(const Foo* p)
-  {
-      return to_python(const_cast(p));
-  }
-BOOST_PYTHON_END_CONVERSION_NAMESPACE
-
- -This will cause the Foo* to be treated as though it were an owning smart -pointer, even though it's not. Be sure you don't use the reference for anything -from Python once the pointer becomes invalid, though. Don't worry too much about -the const_cast<> above: Const-correctness is completely lost -to Python anyway! - -

[In/]Out Parameters and Immutable Types

- -

If you have an interface that uses non-const pointers (or references) as -in/out parameters to types which in Python are immutable (e.g. int, string), -there simply is no way to get the same interface in Python. You must -resort to transforming your interface with simple thin wrappers as shown below: -

-const void f(int* in_out_x); // original function
-const int f_wrapper(int in_x) { f(in_x); return in_x; }
-  ...
-my_module.def(f_wrapper, "f");
-
- -

Of course, [in/]out parameters commonly occur only when there is already a -return value. You can handle this case by returning a Python tuple: -

-typedef unsigned ErrorCode;
-const char* f(int* in_out_x); // original function
- ...
-#include 
-const boost::python::tuple f_wrapper(int in_x) { 
-  const char* s = f(in_x); 
-  return boost::python::tuple(s, in_x);
-}
-  ...
-my_module.def(f_wrapper, "f");
-
-

Now, in Python: -

->>> str,out_x = f(3)

- c++boost.gif (8819 bytes)Special Method and - Operator Support -

-

- Overview -

-

- Py_cpp supports all of the standard - special method names supported by real Python class instances - except __complex__ (more on the reasons below). In addition, it can quickly and easily expose - suitable C++ functions and operators as Python operators. The following - categories of special method names are supported: -

- -

Basic Customization

- - -

- Python provides a number of special operators for basic customization of a - class. Only a brief description is provided below; more complete - documentation can be found here. - -

-
- __init__(self) -
- Initialize the class instance. For extension classes not subclassed in - Python, this is provided by the - boost::python::constructor<...>() construct and should not be explicitly defed. -
- __del__(self) -
- Called when the extension instance is about to be destroyed. -
- __repr__(self) -
- Create a string representation from which the object can be - reconstructed. -
- __str__(self) -
- Create a string representation which is suitable for printing. -
- __cmp__(self, other) -
- Three-way compare function, used to implement comparison operators - (< etc.) Should return a negative integer if self < other - , zero if self == other , a positive integer if - self > other . -
- __hash__(self) -
- Called for the key object for dictionary operations, and by the - built-in function hash(). Should return a 32-bit integer usable as a - hash value for dictionary operations (only allowed if __cmp__ is also - defined) -
- __nonzero__(self) -
- called if the object is used as a truth value (e.g. in an if - statement) -
- __call__ (self[, args...]) -
-Called when the instance is “called” as a function; if this method -is defined, x(arg1, arg2, ...) is a shorthand for -x.__call__(arg1, arg2, ...). -
- - If we have a suitable C++ function that supports any of these features, - we can export it like any other function, using its Python special name. - For example, suppose that class Foo provides a string - conversion function: -
-std::string to_string(Foo const& f)
-{
-    std::ostringstream s;
-    s << f;
-    return s.str();
-}
-
- This function would be wrapped like this: -
-boost::python::class_builder<Foo> foo_class(my_module, "Foo");
-foo_class.def(&to_string, "__str__");
-
- Note that py_cpp also supports automatic wrapping of - __str__ and __cmp__. This is explained in the next section and the Table of - Automatically Wrapped Methods. - -

Numeric Operators

- -

- Numeric operators can be exposed manually, by defing C++ - [member] functions that support the standard Python numeric - protocols. This is the basic same technique used to expose - to_string() as __str__() above, and is covered in detail below. Py_cpp also supports - automatic wrapping of numeric operators whenever they have already - been defined in C++. - -

Exposing C++ Operators Automatically

- -

-Supose we wanted to expose a C++ class - BigNum which supports addition, so that we can write (in C++): -

-BigNum a, b, c;
-...
-c = a + b;
-
-

- To enable the same functionality in Python, we first wrap the - BigNum class as usual: -

-boost::python::class_builder<BigNum> bignum_class(my_module, "BigNum");
-bignum_class.def(boost::python::constructor<>());
-...
-
- Then we export the addition operator like this: - -
-bignum_class.def(boost::python::operators<boost::python::op_add>());
-
- - Since BigNum also supports subtraction, multiplication, and division, we - want to export those also. This can be done in a single command by - “or”ing the operator identifiers together (a complete list of these - identifiers and the corresponding operators can be found in the Table of Automatically Wrapped Methods): -
-bignum_class.def(boost::python::operators<(boost::python::op_sub | boost::python::op_mul | boost::python::op_div)>());
-
- [Note that the or-expression must be enclosed in parentheses.] - -

This form of operator definition can be used to wrap unary and - homogeneous binary operators (a homogeneous operator has left and - right operands of the same type). Now suppose that our C++ library also - supports addition of BigNums and plain integers: - -

-BigNum a, b;
-int i;
-...
-a = b + i;
-a = i + b;
-
- To wrap these heterogeneous operators, we need to specify a different type for - one of the operands. This is done using the right_operand - and left_operand templates: -
-bignum_class.def(boost::python::operators<boost::python::op_add>(), boost::python::right_operand<int>());
-bignum_class.def(boost::python::operators<boost::python::op_add>(), boost::python::left_operand<int>());
-
- Py_cpp uses overloading to register several variants of the same - operation (more on this in the context of - coercion). Again, several operators can be exported at once: -
-bignum_class.def(boost::python::operators<(boost::python::op_sub | boost::python::op_mul | boost::python::op_div)>(),
-                 boost::python::right_operand<int>());
-bignum_class.def(boost::python::operators<(boost::python::op_sub | boost::python::op_mul | boost::python::op_div)>(), 
-                 boost::python::left_operand<int>());
-
- The type of the operand not mentioned is taken from the class being wrapped. In - our example, the class object is bignum_class, and thus the - other operand's type is “BigNum const&”. You can override - this default by explicitly specifying a type in the - operators template: -
-bignum_class.def(boost::python::operators<boost::python::op_add, BigNum>(), boost::python::right_operand<int>());
-
-

- Note that automatic wrapping uses the expression - “left + right” and can be used uniformly - regardless of whether the C++ operators are supplied as free functions - 

-BigNum operator+(BigNum, BigNum)
-
- or as member - functions 
-BigNum::operator+(BigNum).
-

- For the Python built-in functions pow() and - abs(), there is no corresponding C++ operator. Instead, - automatic wrapping attempts to wrap C++ functions of the same name. This - only works if those functions are known in namespace - python. On some compilers (e.g. MSVC) it might be - necessary to add a using declaration prior to wrapping: - -

-namespace boost { namespace python { 
-  using my_namespace::pow;
-  using my_namespace::abs;
-}
-
- -

Wrapping Numeric Operators Manually

-

- In some cases, automatic wrapping of operators may be impossible or - undesirable. Suppose, for example, that the modulo operation for BigNums - is defined by a set of functions mod() (for automatic - wrapping, we would need operator%()): - -

-BigNum mod(BigNum const& left, BigNum const& right);
-BigNum mod(BigNum const& left, int right);
-BigNum mod(int left, BigNum const& right);
-
- -

- In order to create the Python operator "__mod__" from these functions, we - have to wrap them manually: - -

-bignum_class.def((BigNum (*)(BigNum const&, BigNum const&))&mod, "__mod__");
-bignum_class.def((BigNum (*)(BigNum const&, int))&mod, "__mod__");
-
- -

- The third form (with int as left operand) cannot be wrapped - this way. We must first create a function rmod() with the - operands reversed: - -

-BigNum rmod(BigNum const& right, int left)
-{
-    return mod(left, right);
-}
-
- - This function must be wrapped under the name "__rmod__": - -
-bignum_class.def(&rmod,  "__rmod__");
-
- - Many of the possible operator names can be found in the Table of Automatically Wrapped Methods. Special treatment is - necessary to export the ternary pow operator. - -

- Automatic and manual wrapping can be mixed arbitrarily. Note that you - cannot overload the same operator for a given extension class on both - “int” and “float”, because Python implicitly - converts these types into each other. Thus, the overloaded variant - found first (be it “int“ or “float”) will be - used for either of the two types. - -

Coercion

- - - Plain Python can only execute operators with identical types on the left - and right hand side. If it encounters an expression where the types of - the left and right operand differ, it tries to coerce these type to a - common type before invoking the actual operator. Implementing good - coercion functions can be difficult if many type combinations must be - supported. -

- Py_cpp solves this problem the same way that C++ does: with overloading. This technique drastically - simplifies the code neccessary to support operators: you just register - operators for all desired type combinations, and py_cpp automatically - ensures that the correct function is called in each case; there is no - need for user-defined coercion functions. To enable operator - overloading, py_cpp provides a standard coercion which is implicitly - registered whenever automatic operator wrapping is used. -

- If you wrap all operator functions manually, but still want to use - operator overloading, you have to register the standard coercion - function explicitly: - -

-// this is not necessary if automatic operator wrapping is used
-bignum_class.def_standard_coerce();
-
- - If you encounter a situation where you absolutely need a customized - coercion, you can overload the "__coerce__" operator itself. The signature - of a coercion function should look like one of the following (the first is - the safest): - -
-boost::python::tuple custom_coerce(boost::python::reference left, boost::python::reference right);
-boost::python::tuple custom_coerce(PyObject* left, PyObject* right);
-PyObject* custom_coerce(PyObject* left, PyObject* right);
-
- - The resulting tuple must contain two elements which - represent the values of left and right - converted to the same type. Such a function is wrapped as usual: - -
-some_class.def(&custom_coerce, "__coerce__");
-
- - Note that the later use of automatic operator wrapping on a - class_builder or a call to - “some_class.def_standard_coerce()” will cause any - custom coercion function to be replaced by the standard one. - -

The Ternary pow() Operator

- -

- In addition to the usual binary pow(x, y) operator (meaning - xy), Python also provides a ternary variant that implements - xy mod z, presumably using a more efficient algorithm than - concatenation of power and modulo operators. Automatic operator wrapping - can only be used with the binary variant. Ternary pow() must - always be wrapped manually. For a homgeneous ternary pow(), - this is done as usual: - -

-BigNum power(BigNum const& first, BigNum const& second, BigNum const& module);
-typedef BigNum (ternary_function1)(const BigNum&, const BigNum&, const BigNum&);
-...
-bignum_class.def((ternary_function1)&power,  "__pow__");
-
- - If you want to support this function with non-uniform argument - types, wrapping is a little more involved. Suppose you have to wrap: - -
-BigNum power(BigNum const& first, int second, int modulus);
-BigNum power(int first, BigNum const& second, int modulus);
-BigNum power(int first, int second, BigNum const& modulus);
-
- - The first variant can be wrapped as usual: - -
-typedef BigNum (ternary_function2)(const BigNum&, int, int);
-bignum_class.def((ternary_function2)&power,  "__pow__");
-
- - In the second variant, however, BigNum appears only as second - argument, and in the last one it is the third argument. These functions - must be presented to py_cpp such that that the BigNum - argument appears in first position: - -
-BigNum rpower(BigNum const& second, int first, int modulus)
-{
-    return power(first, second, third);
-}
-
-BigNum rrpower(BigNum const& third, int first, int second)
-{
-    return power(first, second, third);
-}
-
- -

These functions must be wrapped under the names "__rpow__" and "__rrpow__" - respectively: - -

-bignum_class.def((ternary_function2)&rpower,  "__rpow__");
-bignum_class.def((ternary_function2)&rrpower,  "__rrpow__");
-
- -Note that "__rrpow__" is an extension not present in plain Python. - -

Sequence and Mapping Operators

- -

- Sequence and mapping operators let wrapped objects behave in accordance - to Python's iteration and access protocols. These protocols differ - considerably from the ones found in C++. For example, Python's typical - iteration idiom looks like -

-for i in S:
-
- -while in C++ one writes - -
-for (iterator i = S.begin(), end = S.end(); i != end)
-
- -

One could try to wrap C++ iterators in order to carry the C++ idiom into - Python. However, this does not work very well because - -

    -
  1. It leads to - non-uniform Python code (wrapped sequences support a usage different from - Python built-in sequences) and - -
  2. Iterators (e.g. std::vector::iterator) are often implemented as plain C++ - pointers which are problematic for any automatic - wrapping system. -
- -

- It is a better idea to support the standard Python - sequence and mapping protocols for your wrapped containers. These - operators have to be wrapped manually because there are no corresponding - C++ operators that could be used for automatic wrapping. The Python - documentation lists the relevant - container operators. In particular, expose __getitem__, __setitem__ - and remember to raise the appropriate Python exceptions - (PyExc_IndexError for sequences, - PyExc_KeyError for mappings) when the requested item is not - present. - -

- In the following example, we expose std::map<std::size_t,std::string>: -

-
-typedef std::map<std::size_t, std::string> StringMap;
-
-// A helper function for dealing with errors. Throw a Python exception
-// if p == m.end().
-void throw_key_error_if_end(
-        const StringMap& m, 
-        StringMap::const_iterator p, 
-        std::size_t key)
-{
-    if (p == m.end())
-    {
-        PyErr_SetObject(PyExc_KeyError, boost::python::converters::to_python(key));
-        throw boost::python::error_already_set();
-    }
-}
-
-// Define some simple wrapper functions which match the Python  protocol
-// for __getitem__, __setitem__, and __delitem__.  Just as in Python, a
-// free function with a “self” first parameter makes a fine class method.
-
-const std::string& get_item(const StringMap& self, std::size_t key)
-{
-    const StringMap::const_iterator p = self.find(key);
-    throw_key_error_if_end(self, p, key);
-    return p->second;
-}
-
-// Sets the item corresponding to key in the map.
-void StringMapPythonClass::set_item(StringMap& self, std::size_t key, const std::string& value)
-{
-    self[key] = value;
-}
-
-// Deletes the item corresponding to key from the map.
-void StringMapPythonClass::del_item(StringMap& self, std::size_t key)
-{
-    const StringMap::iterator p = self.find(key);
-    throw_key_error_if_end(self, p, key);
-    self.erase(p);
-}
-
-class_builder<StringMap> string_map(my_module, "StringMap");
-string_map.def(boost::python::constructor<>());
-string_map.def(&StringMap::size, "__len__");
-string_map.def(get_item, "__getitem__");
-string_map.def(set_item, "__setitem__");
-string_map.def(del_item, "__delitem__");
-
-
-

- Then in Python: -

-
->>> m = StringMap()
->>> m[1]
-Traceback (innermost last):
-  File "<stdin>", line 1, in ?
-KeyError: 1
->>> m[1] = 'hello'
->>> m[1]
-'hello'
->>> del m[1]
->>> m[1]            # prove that it's gone
-Traceback (innermost last):
-  File "<stdin>", line 1, in ?
-KeyError: 1
->>> del m[2]
-Traceback (innermost last):
-  File "<stdin>", line 1, in ?
-KeyError: 2
->>> len(m)
-0
->>> m[0] = 'zero'
->>> m[1] = 'one'
->>> m[2] = 'two'
->>> m[3] = 'three'
->>> len(m)
-4
-
-
- -

Customized Attribute Access

- -

- Just like built-in Python classes, py_cpp extension classes support special - the usual attribute access methods __getattr__, - __setattr__, and __delattr__. - Because writing these functions can - be tedious in the common case where the attributes being accessed are - known statically, py_cpp checks the special names - -

- - to provide functional access to the attribute <name>. This - facility can be used from C++ or entirely from Python. For example, the - following shows how we can implement a “computed attribute” in Python: -
-
->>> class Range(AnyPy_cppExtensionClass):
-...    def __init__(self, start, end):
-...        self.start = start
-...        self.end = end
-...    def __getattr__length__(self):
-...        return self.end - self.start
-...
->>> x = Range(3, 9)
->>> x.length
-6
-
-
-

- Direct Access to Data Members -

-

- Py_cpp uses the special - __xxxattr__<name>__ functionality described above - to allow direct access to data members through the following special - functions on class_builder<> and - extension_class<>: -

-

- Note that the first two functions, used alone, may produce surprising - behavior. For example, when def_getter() is used, the - default functionality for setattr() and - delattr() remains in effect, operating on items in the extension - instance's name-space (i.e., its __dict__). For that - reason, you'll usually want to stick with def_readonly and - def_read_write. -

- For example, to expose a std::pair<int,long> we - might write: -

-
-typedef std::pair<int,long> Pil;
-int first(const Pil& x) { return x.first; }
-long second(const Pil& x) { return x.second; }
-   ...
-my_module.def(first, "first");
-my_module.def(second, "second");
-
-class_builder<Pil> pair_int_long(my_module, "Pair");
-pair_int_long.def(boost::python::constructor<>());
-pair_int_long.def(boost::python::constructor<int,long>());
-pair_int_long.def_read_write(&Pil::first, "first");
-pair_int_long.def_read_write(&Pil::second, "second");
-
-
-

- Now your Python class has attributes first and - second which, when accessed, actually modify or reflect the - values of corresponding data members of the underlying C++ object. Now - in Python: -

-
->>> x = Pair(3,5)
->>> x.first
-3
->>> x.second
-5
->>> x.second = 8
->>> x.second
-8
->>> second(x) # Prove that we're not just changing the instance __dict__
-8
-
-
-

- And what about __complex__? -

-

- That, dear reader, is one problem we don't know how to solve. The - Python source contains the following fragment, indicating the - special-case code really is hardwired: -

-
-/* XXX Hack to support classes with __complex__ method */
-if (PyInstance_Check(r)) { ...
-
-

- A Peek Under the Hood -

-

- Declaring a class_builder<T> causes the instantiation - of an extension_class<T> to which it forwards all - member function calls and which is doing most of the real work. - extension_class<T> is a subclass of - PyTypeObject, the struct which Python's 'C' API uses - to describe a type. An instance of the - extension_class<> becomes the Python type object - corresponding to hello::world. When we add it to the module it goes into the - module's dictionary to be looked up under the name "world". -

- Py_cpp uses C++'s template argument deduction mechanism to determine the - types of arguments to functions (except constructors, for which we must - provide an argument list - because they can't be named in C++). Then, it calls the appropriate - overloaded functions PyObject* - to_python(S) and - S'from_python(PyObject*, - type<S>) which convert between any C++ - type S and a PyObject*, the type which represents a - reference to any Python object in its 'C' API. The extension_class<T> - template defines a whole raft of these conversions (for T, T*, - T&, std::auto_ptr<T>, etc.), using the same inline - friend function technique employed by the boost operators - library. -

- Because the to_python and from_python functions - for a user-defined class are defined by - extension_class<T>, it is important that an instantiation of - extension_class<T> is visible to any code which wraps - a C++ function with a T, T*, const T&, etc. parameter or - return value. In particular, you may want to create all of the classes at - the top of your module's init function, then def the member - functions later to avoid problems with inter-class dependencies. -
