c++boost.gif (8819 bytes)Building an - Extension Module

- -

The build process for Boost is currently undergoing some evolution, - and, it is to be hoped, improvement. The following facts may help: - -

- Makefiles for various platforms and a Visual Studio project - reside in the Boost subdirectory libs/python/build. - Build targets include: - -
    -
  • The boost_python library for static linking with your - extension module. On the various Unices, this library will be - called libboost_python.a. When using Visual C++, the - library will be called boost_python.lib. - -

    -

  • A comprehensive test of Boost.Python features. This test builds - a Boost.Python extension module, then runs Python to import the - module, and runs a series of tests on it using doctest. Source code for the module - and tests is available in the Boost subdirectory - libs/python/test. - -

    -

  • Various examples from the Boost subdirectory - libs/python/example. - All these examples include a doctest modeled - on the comprehensive test above. - -
- -
- There is a group of makefiles with support for simultaneous - compilation on multiple platforms and a consistent set of - features that build the boost_python library for static - linking, the comprehensive test, and all examples in - libs/python/example: - - - Usage of these makefiles is described here. - -
- There is another group of makefiles for GNU make. - These makefiles are less redundant than the makefiles - in the group above, - but the list of compilation targets is not as complete - and there is no support for simultaneous compilation - on multiple platforms. - - - -
- A project workspace for Microsoft Visual Studio is provided at libs/python/build/build.dsw. The - include paths for this project may need to be changed for your - installation. They currently assume that python has been installed at - c:\tools\python. Three configurations of all targets are - supported: - -
    -
  • Release (optimization, -DNDEBUG) - -
  • Debug (no optimization -D_DEBUG) - -
  • DebugPython (no optimization, -D_DEBUG - -DBOOST_DEBUG_PYTHON) -
- -

When extension modules are built with Visual C++ using - -D_DEBUG, Python defaults to force linking with a - special debugging version of the Python DLL. Since this debug DLL - isn't supplied with the default Python installation for Windows, - Boost.Python uses boost/python/detail/wrap_python.hpp - to temporarily undefine _DEBUG when Python.h is - #included. - -

If you want the extra runtime checks available with the debugging - version of the library, #define BOOST_DEBUG_PYTHON to - re-enable library forcing, and link with the DebugPython version of - boost_python.lib. You'll need to get the debugging version - of the Python executable (python_d.exe) and DLL - (python20_d.dll or python15_d.dll). The Python - sources include project files for building these. If you download them, change the name of the - top-level directory to src, and install it under - c:\tools\python, the workspace supplied by Boost.Python will - be able to use it without modification. Just open - c:\tools\python\src\pcbuild\pcbuild.dsw and invoke "build - all" to generate all the debugging targets. - -

If you do not #define BOOST_DEBUG_PYTHON, be sure that - any source files #include <boost/python/detail/wrap_python.hpp> - instead of the usual Python.h, or you will have link - incompatibilities.
- -

- If your platform isn't directly supported, you can build a static - library from the following source files (in the Boost subdirectory - libs/python/src), or compile them directly and link the - resulting objects into your extension module: - - - -

CXX

-

- Like Boost.Python, CXX attempts to - provide a C++-oriented interface to Python. In most cases, as with the - boost library, it relieves the user from worrying about - reference-counts. Both libraries automatically convert thrown C++ - exceptions into Python exceptions. As far as I can tell, CXX has 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. While you're hardly - programming directly to the ``bare metal'' with CXX, it basically - presents a ``C++-ized'' version of the Python 'C' API. Some fraction of - that capability is available in Boost.Python through boost/python/objects.hpp, - which provides C++ objects corresponding to Python lists, tuples, - strings, and dictionaries, and through boost/python/callback.hpp, - which allows you to call back into python with C++ arguments. - -

- 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 Boost.Python, 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 Boost.Python doesn't have - this problem[sic]... IMHO overloaded functions are very important to - wrap correctly.''
-Prabhu Ramachandran -
- -

- By contrast, Boost.Python doesn't attempt to parse C++ - the problem is simply - too complex to do correctly. Technically, one does - write code by hand to use Boost.Python. 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 Boost.Python, 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 Boost.Python, 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: -

    -
  • Does it support overriding of virtual functions? -
  • What about overriding private or protected virtual functions (the documentation indicates -that only public interfaces are supported)? -
  • Which C++ language constructs are supportd? -
  • Does it support implicit conversions between wrapped C++ classes that have -an inheritance relationship? -
  • Does it support smart pointers? -
-

- 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 Boost.Python - 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: -

    -
  • Zope is entirely 'C' language-based. It doesn't require a C++ - compiler, so it's much more portable than Boost.Python, which stresses - the limits of even some modern C++ implementations. - -
  • - Boost.Python lifts the burden on the user to parse and convert function - argument types. Zope provides no such facility. -
  • - Boost.Python lifts the burden on the user to maintain Python - reference-counts. -
  • - Boost.Python supports function overloading; Zope does not. -
  • - Boost.Python supplies a simple mechanism for exposing read-only and - read/write access to data members of the wrapped C++ type as Python - attributes. -
  • - Writing a Zope ExtensionClass is significantly more complex than - exposing a C++ class to python using Boost.Python (mostly a summary of the - previous 4 items). A - Zope Example illustrates the differences. -
  • - Zope's ExtensionClasses are specifically motivated by ``the need for a - C-based persistence mechanism''. Boost.Python's are motivated by the desire - to simply reflect a C++ API into Python with as little modification as - possible. -
  • - The following Zope restriction does not apply to Boost.Python: ``At most one - base extension direct or indirect super class may define C data - members. If an extension subclass inherits from multiple base - extension classes, then all but one must be mix-in classes that - provide extension methods but no data.'' -
  • - Zope requires use of the somewhat funky inheritedAttribute (search for - ``inheritedAttribute'' on this page) - method to access base class methods. In Boost.Python, base class methods can - be accessed in the usual way by writing - ``BaseClass.method''. -
  • - Zope supplies some creative but esoteric idioms such as - Acquisition. No specific support for this is built into Boost.Python. -
  • - Zope's ComputedAttribute support is designed to be used from Python. - The analogous feature of - Boost.Python can be used from C++ or Python. The feature is arguably - easier to use in Boost.Python. -

Cross-extension-module dependencies

- -It is good programming practice to organize large projects as modules -that interact with each other via well defined interfaces. With -Boost.Python it is possible to reflect this organization at the C++ -level at the Python level. This is, each logical C++ module can be -organized as a separate Python extension module. - -

-At first sight this might seem natural and straightforward. However, it -is a fairly complex problem to establish cross-extension-module -dependencies while maintaining the same ease of use Boost.Python -provides for classes that are wrapped in the same extension module. To -a large extent this complexity can be hidden from the author of a -Boost.Python extension module, but not entirely. - -

-

The recipe

- -Suppose there is an extension module that exposes certain instances of -the C++ std::vector template library such that it can be used -from Python in the following manner: - -
-import std_vector
-v = std_vector.double([1, 2, 3, 4])
-v.push_back(5)
-v.size()
-
- -Suppose the std_vector module is done well and reflects all -C++ functions that are useful at the Python level, for all C++ built-in -data types (std_vector.int, std_vector.long, etc.). - -

-Suppose further that there is statistic module with a C++ class that -has constructors or member functions that use or return a -std::vector. For example: - -

-class xy {
-  public:
-    xy(const std::vector<double>& x, const std::vector<double>& y) : m_x(x), m_y(y) {}
-    const std::vector<double>& x() const { return m_x; }
-    const std::vector<double>& y() const { return m_y; }
-    double correlation();
-  private:
-    std::vector<double> m_x;
-    std::vector<double> m_y;
-}
-
- -What is more natural than reusing the std_vector extension -module to expose these constructors or functions to Python? - -

-Unfortunately, what seems natural needs a little work in both the -std_vector and the statistics module. - -

-In the std_vector extension module, -std::vector<double> is exposed to Python in the usual -way with the class_builder<> template. To also enable the -automatic conversion of std::vector<double> function -arguments or return values in other Boost.Python C++ modules, the -converters that convert a std::vector<double> C++ object -to a Python object and vice versa (i.e. the to_python() and -from_python() template functions) have to be exported. For -example: - -

-  #include <boost/python/cross_module.hpp>
-  //...
-  class_builder<std::vector<double> > v_double(std_vector_module, "double");
-  export_converters(v_double);
-
- -In the extension module that wraps class xy we can now import -these converters with the import_converters<> template. -For example: - -
-  #include <boost/python/cross_module.hpp>
-  //...
-  import_converters<std::vector<double> > v_double_converters("std_vector", "double");
-
- -That is all. All the attributes that are defined for -std_vector.double in the std_vector Boost.Python -module will be available for the returned objects of xy.x() -and xy.y(). Similarly, the constructor for xy will -accept objects that were created by the std_vectormodule. - -
-

Placement of import_converters<> template instantiations

- -import_converts<> can be viewed as a drop-in replacement -for class_wrapper<>, and the recommendations for the -placement of class_wrapper<> template instantiations -also apply to to import_converts<>. In particular, it is -important that an instantiation of class_wrapper<> is -visible to any code which wraps a C++ function with a T, -T*, const T&, etc. parameter or return value. -Therefore you may want to group all class_wrapper<> and -import_converts<> instantiations at the top of your -module's init function, then def() the member functions later -to avoid problems with inter-class dependencies. - -
-

Non-copyable types

- -export_converters() instantiates C++ template functions that -invoke the copy constructor of the wrapped type. For a type that is -non-copyable this will result in compile-time error messages. In such a -case, export_converters_noncopyable() can be used to export -the converters that do not involve the copy constructor of the wrapped -type. For example: - -
-class_builder<store> py_store(your_module, "store");
-export_converters_noncopyable(py_store);
-
- -The corresponding import_converters<> statement does not -need any special attention: - -
-import_converters<store> py_store("noncopyable_export", "store");
-
- -
-

Python module search path

- -The std_vector and statistics modules can now be used -in the following way: - -
-import std_vector
-import statistics
-x = std_vector.double([1, 2, 3, 4])
-y = std_vector.double([2, 4, 6, 8])
-xy = statistics.xy(x, y)
-xy.correlation()
-
- -In this example it is clear that Python has to be able to find both the -std_vector and the statistics extension module. In -other words, both extension modules need to be in the Python module -search path (sys.path). - -

-The situation is not always this obvious. Suppose the -statistics module has a random() function that -returns a vector of random numbers with a given length: - -

-import statistics
-x = statistics.random(5)
-y = statistics.random(5)
-xy = statistics.xy(x, y)

- -A naive user will not easily anticipate that the std_vector -module is used to pass the x and y vectors around. If -the std_vector module is in the Python module search path, -this form of ignorance is of no harm. On the contrary, we are glad -that we do not have to bother the user with details like this. - -

-If the std_vector module is not in the Python module search -path, a Python exception will be raised: - -

-    x = statistics.random(5)
-ImportError: No module named std_vector
-
- -As is the case with any system of a non-trivial complexity, it is -important that the setup is consistent and complete. - -
-

Two-way module dependencies

- -Boost.Python supports two-way module dependencies. This is best -illustrated by a simple example. - -

-Suppose there is a module ivect that implements vectors of -integers, and a similar module dvect that implements vectors -of doubles. We want to be able do convert an integer vector to a double -vector and vice versa. For example: - -

-import ivect
-iv = ivect.ivect((1,2,3,4,5))
-dv = iv.as_dvect()
-
- -The last expression will implicitly import the dvect module in -order to enable the conversion of the C++ representation of -dvect to a Python object. The analogous is possible for a -dvect: - -
-import dvect
-dv = dvect.dvect((1,2,3,4,5))
-iv = dv.as_ivect()
-
- -Now the ivect module is imported implicitly. - -

-Note that the two-way dependencies are possible because the -dependencies are resolved only when needed. This is, the initialization -of the ivect module does not rely on the dvect -module, and vice versa. Only if as_dvect() or -as_ivect() is actually invoked will the corresponding module -be implicitly imported. This also means that, for example, the -dvect module does not have to be available at all if -as_dvect() is never used. - -

-

Clarification of compile-time and link-time dependencies

- -Boost.Python's support for resolving cross-module dependencies at -runtime does not imply that compile-time dependencies are eliminated. -For example, the statistics extension module in the example above will -need to #include <vector>. This is immediately obvious -from the definition of class xy. - -

-If a library is wrapped that consists of both header files and compiled -components (e.g. libdvect.a, dvect.lib, etc.), both -the Boost.Python extension module with the -export_converters() statement and the module with the -import_converters<> statement need to be linked against -the object library. Ideally one would build a shared library (e.g. -libdvect.so, dvect.dll, etc.). However, this -introduces the issue of having to configure the search path for the -dynamic loading correctly. For small libraries it is therefore often -more convenient to ignore the fact that the object files are loaded -into memory more than once. - -

-

Summary of motivation for cross-module support

- -The main purpose of Boost.Python's cross-module support is to allow for -a modular system layout. With this support it is straightforward to -reflect C++ code organization at the Python level. Without the -cross-module support, a multi-purpose module like std_vector -would be impractical because the entire wrapper code would somehow have -to be duplicated in all extension modules that use it, making them -harder to maintain and harder to build. - -

-Another motivation for the cross-module support is that two extension -modules that wrap the same class cannot both be imported into Python. -For example, if there are two modules A and B that -both wrap a given class X, this will work: - -

-import A
-x = A.X()
-
- -This will also work: - -
-import B
-x = B.X()
-
- -However, this will fail: - -
-import A
-import B
-python: /net/cci/rwgk/boost/boost/python/detail/extension_class.hpp:866:
-static void boost::python::detail::class_registry<X>::register_class(boost::python::detail::extension_class_base *):
-Assertion `static_class_object == 0' failed.
-Abort
-
- -A good solution is to wrap class X only once. Depending on the -situation, this could be done by module A or B, or an -additional small extension module that only wraps and exports -class X. - -

-Finally, there can be important psychological or political reasons for -using the cross-module support. If a group of classes is lumped -together with many others in a huge module, the authors will have -difficulties in being identified with their work. The situation is -much more transparent if the work is represented by a module with a -recognizable name. This is not just a question of strong egos, but also -of getting credit and funding. - -

-

Why not use export_converters() universally?

- -There is some overhead associated with the Boost.Python cross-module -support. Depending on the platform, the size of the code generated by -export_converters() is roughly 10%-20% of that generated -by class_builder<>. For a large extension module with -many wrapped classes, this could mean a significant difference. -Therefore the general recommendation is to use -export_converters() only for classes that are likely to -be used as function arguments or return values in other modules. - -

- Wrapping enums -

- -

Because there is in general no way to deduce that a value of arbitrary type T -is an enumeration constant, the Boost Python Library 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, we provide a shorthand for these functions. You just need to cause -boost::python::enum_as_int_converters<EnumType> to be -instantiated, where -EnumType is your enumerated type. There are two convenient ways to do this: - -

    -
  1. Explicit instantiation: - -
    -  template class boost::python::enum_as_int_converters<my_enum>;
-
    - -Some buggy C++ implementations require a class to be instantiated in the same -namespace in which it is defined. In that case, the simple incantation above becomes: - -
    -
    -   ...
-} // close my_namespace
-
-// drop into namespace python and explicitly instantiate
-namespace boost { namespace python {
-  template class enum_as_int_converters<my_enum_type>;
-}} // namespace boost::python
-
-namespace my_namespace { // re-open my_namespace
-   ...
-
    -
    - - -
  2. If you have such an implementation, you may find this technique more convenient -
    -// instantiate as base class in any namespace
-struct EnumTypeConverters
-    : boost::python::enum_as_int_converters<EnumType>
-{
-};
-
    -
- -

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. These bind the corresponding enum values to the appropriate -names so they can be used from Python: - -

-mymodule.add(boost::python::make_ref(enum_value_1), "enum_value_1");
-mymodule.add(boost::python::make_ref(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_builder.add(boost::python::to_python(enum_value_1), "enum_value_1");
-my_class_builder.add(boost::python::to_python(enum_value_2), "enum_value_2");
-...

- A Simple Example -

-

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

-
-#include <string>
-
-namespace { // Avoid cluttering the global namespace.
-
-  // A couple of simple C++ functions that we want to expose to Python.
-  std::string greet() { return "hello, world"; }
-  int square(int number) { return number * number; }
-}
-
-
-
-

- Here is the C++ code for a python module called getting_started1 - which exposes the API. -

-
-#include <boost/python/class_builder.hpp>
-namespace python = boost::python;
-
-BOOST_PYTHON_MODULE_INIT(getting_started1)

-  // A friendly class.
-  class hello
-  {

-  }
-}
-
-

- To expose the class, we use a class_builder in addition to the - module_builder from the previous example. Class member functions - are exposed by using the def() member function on the - class_builder: -

-#include <boost/python/class_builder.hpp>
-namespace python = boost::python;
-
-BOOST_PYTHON_MODULE_INIT(getting_started2)
-{
-  try
-  {
-    // Create an object representing this extension module.
-    python::module_builder this_module("getting_started2");
-
-    // Create the Python type object for our extension class.
-    python::class_builder<hello> hello_class(this_module, "hello");
-
-    // Add the __init__ function.
-    hello_class.def(python::constructor<std::string>());
-    // Add a regular member function.
-    hello_class.def(&hello::greet, "greet");
-
-    // Add invite() as a regular function to the module.
-    this_module.def(invite, "invite");
-
-    // Even better, invite() can also be made a member of hello_class!!!
-    hello_class.def(invite, "invite");
-  }
-  catch(...)
-  {
-    python::handle_exception(); // Deal with the exception for Python
-  }

-Now we can use the class normally from Python: - -

->>> from getting_started2 import *
->>> hi = hello('California')
->>> hi.greet()
-'Hello from California'
->>> invite(hi)
-'Hello from California! Please come soon!'
->>> hi.invite()
-'Hello from California! Please come soon!'
-
- -Notes:
    -
  • We expose the class' constructor by calling def() on the - class_builder with an argument whose type is - constructor<params>, where params - matches the list of constructor argument types: - - -
  • Regular member functions are defined by calling def() with a - member function pointer and its Python name: - -
  • Any function added to a class whose initial argument matches the class (or -any base) will act like a member function in Python. - -
  • To define a nested class, just pass the enclosing -class_builder (instead of a module_builder) as the -first argument to the nested class_builder's constructor. - - -
-

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

->>> class wordy(hello):
-...     def greet(self):
-...         return hello.greet(self) + ', where the weather is fine'
-...
->>> hi2 = wordy('Florida')
->>> hi2.greet()
-'Hello from Florida, where the weather is fine'
->>> invite(hi2)
-'Hello from Florida! Please come soon!'
-
-

- Pretty cool! You can't do that with an ordinary Python extension type! - - Of course, you may now have a slightly empty feeling in the pit of - your little pythonic stomach. Perhaps you wanted to see the following - wordy invitation: - -

-'Hello from Florida, where the weather is fine! Please come soon!'
-
- - After all, invite calls hello::greet(), and you - reimplemented that in your Python subclass, wordy. 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. The Boost Python Library 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. Boost.Python 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. Boost.Python classes are actually cleaner than - Python classes in some subtle ways; a more detailed discussion will - follow (someday).

Synopsis

-

- Use the Boost Python Library to quickly and easily export a C++ library to Python such that the Python interface is - very similar to the C++ interface. It is designed to be minimally - intrusive on your C++ design. In most cases, you should not have to alter - your C++ classes in any way in order to use them with Boost.Python. The system - should simply ``reflect'' your C++ classes and functions into - Python. The major features of Boost.Python include support for: -

-among others. - - -

Supported Platforms

Boost.Python is known to have been tested in the following configurations: - -

Credits

-
    -
  • David Abrahams originated - and wrote most of the library, and continues to coordinate development. - -
  • Ullrich Koethe - had independently developed a similar system. When he discovered Boost.Python, - he generously contributed countless hours of coding and much insight into - improving it. He is responsible for an early version of the support for function overloading and wrote the support for - reflecting C++ inheritance - relationships. He has helped to improve error-reporting from both - Python and C++, and has designed an extremely easy-to-use way of - exposing numeric operators, including - a way to avoid explicit coercion by means of overloading. - -
  • Ralf W. - Grosse-Kunstleve contributed pickle support - and numerous other small improvements. He's working on a way to allow - types exported by multiple modules to interact. - -
  • The members of the boost mailing list and the Python community - supplied invaluable early feedback. In particular, Ron Clarke, Mark Evans, - Anton Gluck, Chuck Ingold, Prabhu Ramachandran, and Barry Scott took the - brave step of trying to use Boost.Python while it was still in early - stages of development. - -
  • The development of Boost.Python wouldn't have been possible without - the generous support of Dragon - Systems/Lernout and Hauspie, Inc who supported its development as an - open-source project. -

Inheritance in Python

- -

- Boost.Python extension classes support single and multiple-inheritance in - Python, just like regular Python classes. You can arbitrarily mix - built-in Python classes with extension classes in a derived class' - tuple of bases. Whenever a Boost.Python 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

-

- Boost.Python 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 <boost/python/class_builder.hpp>
-
-// namespace alias for code brevity
-namespace python = boost::python;
-
-BOOST_PYTHON_MODULE_INIT(my_module)
-{
-    try
-    {
-       python::module_builder my_module("my_module");
-
-       python::class_builder<Base> base_class(my_module, "Base");
-       base_class.def(python::constructor<void>());
-
-       python::class_builder<Derived> derived_class(my_module, "Derived");
-       derived_class.def(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(...)
-    {
-       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(); };
-

-   ...
-   python::class_builder<Base> base2_class(my_module, "Base2");
-   base2_class.def(python::constructor<void>());
-
-   python::class_builder<Derived2> derived2_class(my_module, "Derived2");
-   derived2_class.def(python::constructor<void>());
-   derived_class.declare_base(base_class, 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;
-};
-  ...
-
-BOOST_PYTHON_MODULE_INIT(overload_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 works as follows: - -

    - -
  • Attribute lookup for extension classes proceeds in the - usual Python way using a depth-first, left-to-right search. When a - class is found which has a matching attribute, only functions overloaded - in the context of that class are candidates for overload resolution. In - this sense, overload resolution mirrors the C++ mechanism, where a name - in a derived class ``hides'' all functions with the same name from a base - class. -

    - -

  • Within a name-space context (extension class or module), overloaded - functions are tried in the same order they were - def()ed. The first function whose signature can be made to - match each argument passed is the one which is ultimately called. - This means in particular that you cannot overload the same function on - both ``int'' and ``float'' because Python - automatically converts either of the two types into the other one. - If the ``float'' overload is found first, it is used - also used for arguments of type ``int'' as well, and the - ``int'' version of the function is never invoked. -

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 hello::greet() is a virtual -member function: - -

-class hello
-{
- public:
-    hello(const std::string& country) { this->country = country; }
-    virtual std::string greet() const { return "Hello from " + country; }
-    virtual ~hello(); // Good practice 
-    ...
-};
-
- -

- 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 (usually - called self) that holds a pointer to the Python object corresponding - to our C++ hello instance. - -
  2. For each exposed constructor of the - base class T, a constructor which takes the same parameters preceded by an initial - PyObject* argument. The initial argument should be stored in the self data - member described above. - -
  3. If the class being wrapped is ever returned by - value from a wrapped function, be sure you do the same for the - T's copy constructor: you'll need a constructor taking arguments - (PyObject*, const T&). - -
  4. An implementation of each virtual function you may - wish to override in Python which uses - callback<return-type>::call_method(self, "name", args...) to call - the Python override. - -
  5. 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 T 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 hello_callback : hello
-{
-    // hello constructor storing initial self_ parameter
-    hello_callback(PyObject* self_, const std::string& x) // 2
-        : hello(x), self(self_) {}
-
-    // In case hello is returned by-value from a wrapped function
-    hello_callback(PyObject* self_, const hello& x) // 3
-        : hello(x), self(self_) {}
-
-    // Override greet to call back into Python
-    std::string greet() const // 4
-        { return boost::python::callback<std::string>::call_method(self, "greet"); }
-
-    // Supplies the default implementation of greet
-    static std::string default_greet(const hello& self_) const // 5
-        { return self_.hello::greet(); }
- private:
-    PyObject* self; // 1
-};
-
- -

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

-// Create the Python type object for our extension class
-boost::python::class_builder<hello,hello_callback> hello_class(hello, "hello");
-// Add a virtual member function
-hello_class.def(&hello::greet, "greet", &hello_callback::default_greet);
-
- -

- Now our Python subclass of hello behaves as expected: - -

->>> class wordy(hello):
-...     def greet(self):
-...         return hello.greet(self) + ', where the weather is fine'
-...
->>> hi2 = wordy('Florida')
->>> hi2.greet()
-'Hello from Florida, where the weather is fine'
->>> invite(hi2)
-'Hello from Florida, where the weather is fine! Please come soon!'
-
-

- *You may ask, "Why do we need this derived - class? This could have been designed so that everything gets done right - inside of hello." One of the goals of Boost.Python 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;
-    int calls_pure(int x) { return pure(x) + 1000; }
-};
-
-struct baz_callback {
-    int pure(int x) { boost::python::callback<int>::call_method(m_self, "pure", x); }
-};
-
-BOOST_PYTHON_MODULE_INIT(foobar)
-{
-    try
-    {
-       boost::python::module_builder foobar("foobar");
-       boost::python::class_builder<baz,baz_callback> baz_class("baz");
-       baz_class.def(&baz::calls_pure, "calls_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
->>> x.calls_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
->>> y.calls_pure(99)
-1100
-
- -

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). - -

Boost.Python Pickle Support

- -Pickle is a Python module for object serialization, also known -as persistence, marshalling, or flattening. - -

-It is often necessary to save and restore the contents of an object to -a file. One approach to this problem is to write a pair of functions -that read and write data from a file in a special format. A powerful -alternative approach is to use Python's pickle module. Exploiting -Python's ability for introspection, the pickle module recursively -converts nearly arbitrary Python objects into a stream of bytes that -can be written to a file. - -

-The Boost Python Library supports the pickle module by emulating the -interface implemented by Jim Fulton's ExtensionClass module that is -included in the -ZOPE -distribution. -This interface is similar to that for regular Python classes as -described in detail in the -Python Library Reference for pickle. - -

-

The Boost.Python Pickle Interface

- -At the user level, the Boost.Python pickle interface involves three special -methods: - -
-
-__getinitargs__ -
- When an instance of a Boost.Python extension class is pickled, the - pickler tests if the instance has a __getinitargs__ method. - This method must return a Python tuple (it is most convenient to use - a boost::python::tuple). When the instance is restored by the - unpickler, the contents of this tuple are used as the arguments for - the class constructor. - -

- If __getinitargs__ is not defined, the class constructor - will be called without arguments. - -

-

-__getstate__ - -
- When an instance of a Boost.Python extension class is pickled, the - pickler tests if the instance has a __getstate__ method. - This method should return a Python object representing the state of - the instance. - -

- If __getstate__ is not defined, the instance's - __dict__ is pickled (if it is not empty). - -

-

-__setstate__ - -
- When an instance of a Boost.Python extension class is restored by the - unpickler, it is first constructed using the result of - __getinitargs__ as arguments (see above). Subsequently the - unpickler tests if the new instance has a __setstate__ - method. If so, this method is called with the result of - __getstate__ (a Python object) as the argument. - -

- If __setstate__ is not defined, the result of - __getstate__ must be a Python dictionary. The items of this - dictionary are added to the instance's __dict__. - -

- -If both __getstate__ and __setstate__ are defined, -the Python object returned by __getstate__ need not be a -dictionary. The __getstate__ and __setstate__ methods -can do what they want. - -
-

Pitfalls and Safety Guards

- -In Boost.Python extension modules with many extension classes, -providing complete pickle support for all classes would be a -significant overhead. In general complete pickle support should only be -implemented for extension classes that will eventually be pickled. -However, the author of a Boost.Python extension module might not -anticipate correctly which classes need support for pickle. -Unfortunately, the pickle protocol described above has two important -pitfalls that the end user of a Boost.Python extension module might not -be aware of: - -
-
-Pitfall 1: -Both __getinitargs__ and __getstate__ are not defined. - -
- In this situation the unpickler calls the class constructor without - arguments and then adds the __dict__ that was pickled by - default to that of the new instance. - -

- However, most C++ classes wrapped with Boost.Python will have member - data that are not restored correctly by this procedure. To alert the - user to this problem, a safety guard is provided. If both - __getinitargs__ and __getstate__ are not defined, - Boost.Python tests if the class has an attribute - __dict_defines_state__. An exception is raised if this - attribute is not defined: - -

-    RuntimeError: Incomplete pickle support (__dict_defines_state__ not set)
-
- - In the rare cases where this is not the desired behavior, the safety - guard can deliberately be disabled. The corresponding C++ code for - this is, e.g.: - -
-    class_builder<your_class> py_your_class(your_module, "your_class");
-    py_your_class.dict_defines_state();
-
- - It is also possible to override the safety guard at the Python level. - E.g.: - -
-    import your_bpl_module
-    class your_class(your_bpl_module.your_class):
-      __dict_defines_state__ = 1
-
- -

-

-Pitfall 2: -__getstate__ is defined and the instance's __dict__ is not empty. - -
- The author of a Boost.Python extension class might provide a - __getstate__ method without considering the possibilities - that: - -

-

    -
  • - his class is used in Python as a base class. Most likely the - __dict__ of instances of the derived class needs to be - pickled in order to restore the instances correctly. - -

    -

  • - the user adds items to the instance's __dict__ directly. - Again, the __dict__ of the instance then needs to be - pickled. - -
-

- - To alert the user to this highly unobvious problem, a safety guard is - provided. If __getstate__ is defined and the instance's - __dict__ is not empty, Boost.Python tests if the class has - an attribute __getstate_manages_dict__. An exception is - raised if this attribute is not defined: - -

-    RuntimeError: Incomplete pickle support (__getstate_manages_dict__ not set)
-
- - To resolve this problem, it should first be established that the - __getstate__ and __setstate__ methods manage the - instances's __dict__ correctly. Note that this can be done - both at the C++ and the Python level. Finally, the safety guard - should intentionally be overridden. E.g. in C++: - -
-    class_builder<your_class> py_your_class(your_module, "your_class");
-    py_your_class.getstate_manages_dict();
-
- - In Python: - -
-    import your_bpl_module
-    class your_class(your_bpl_module.your_class):
-      __getstate_manages_dict__ = 1
-      def __getstate__(self):
-        # your code here
-      def __setstate__(self, state):
-        # your code here
-
-
- -
-

Practical Advice

- -
    -
  • - Avoid using __getstate__ if the instance can also be - reconstructed by way of __getinitargs__. This automatically - avoids Pitfall 2. - -

    -

  • - If __getstate__ is required, include the instance's - __dict__ in the Python object that is returned. - -
- -
-

Examples

- -There are three files in boost/libs/python/example that -show how so provide pickle support. - -

pickle1.cpp

- - The C++ class in this example can be fully restored by passing the - appropriate argument to the constructor. Therefore it is sufficient - to define the pickle interface method __getinitargs__. - -

pickle2.cpp

- - The C++ class in this example contains member data that cannot be - restored by any of the constructors. Therefore it is necessary to - provide the __getstate__/__setstate__ pair of - pickle interface methods. - -

- For simplicity, the __dict__ is not included in the result - of __getstate__. This is not generally recommended, but a - valid approach if it is anticipated that the object's - __dict__ will always be empty. Note that the safety guards - will catch the cases where this assumption is violated. - -

pickle3.cpp

- - This example is similar to pickle2.cpp. However, the - object's __dict__ is included in the result of - __getstate__. This requires more code but is unavoidable - if the object's __dict__ is not always empty. - -

The Problem With Pointers

- -

-In general, raw pointers passed to or returned from functions are problematic -for Boost.Python 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: -

    - -
  • Both const- and non-const pointers to wrapped class instances can be passed -to C++ functions. - -
  • Values of type const char* are interpreted as -null-terminated 'C' strings and when passed to or returned from C++ functions are -converted from/to Python strings. - -
- -

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 that return a pointer to an individual const -T, and T is a wrapped class, you may be able to write a ``thin -converting wrapper'' over those two functions as follows: - -

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

-Foo must have a public copy constructor for this technique to work, since Boost.Python -converts const T& values to_python by copying the T -value into a new extension instance. - -

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::python_extension_class_converters<Foo>::smart_ptr_to_python(p);
-  }
-
-  PyObject* to_python(const Foo* p)
-  {
-      return to_python(const_cast<Foo*>(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 <boost/python/objects.hpp>
-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)

Rich Comparisons

- -
-In Python versions up to and including Python 2.0, support for -implementing comparisons on user-defined classes and extension types -was quite simple. Classes could implement a __cmp__ method -that was given two instances of a class as arguments, and could only -return 0 if they were equal or +1 or -1 if -they were not. The method could not raise an exception or return -anything other than an integer value. -In Python 2.1, Rich Comparisons were added (see -PEP 207). -Python classes can now individually overload each of the <, <=, ->, >=, ==, and != operations. - -

-For more detailed information, search for "rich comparison" -here. - -

-Boost.Python supports both automatic overloading and manual overloading -of the Rich Comparison operators. The compile-time support is -independent of the Python version that is used when compiling -Boost.Python extension modules. That is, op_lt for example can -always be used, and the C++ operator< will always be bound -to the Python method __lt__. However, the run-time -behavior will depend on the Python version. - -

-With Python versions before 2.1, the Rich Comparison operators will not -be called by Python when any of the six comparison operators -(<, <=, ==, !=, ->, >=) is used in an expression. The only way -to access the corresponding methods is to call them explicitly, e.g. -a.__lt__(b). Only with Python versions 2.1 or higher will -expressions like a < b work as expected. - -

-To support Rich Comparisions, the Python C API was modified between -Python versions 2.0 and 2.1. A new slot was introduced in the -PyTypeObject structure: tp_richcompare. For backwards -compatibility, a flag (Py_TPFLAGS_HAVE_RICHCOMPARE) has to be -set to signal to the Python interpreter that Rich Comparisions are -supported by a particular type. -There is only one flag for all the six comparison operators. -When any of the six operators is wrapped automatically or -manually, Boost.Python will set this flag. Attempts to use comparison -operators at the Python level that are not defined at the C++ level -will then lead to an AttributeError when the Python 2.1 -(or higher) interpreter tries, e.g., a.__lt__(b). That -is, in general all six operators should be supplied. Automatically -wrapped operators and manually wrapped operators can be mixed. For -example:

-    boost::python::class_builder<code> py_code(this_module, "code");
-
-    py_code.def(boost::python::constructor<>());
-    py_code.def(boost::python::constructor<int>());
-    py_code.def(boost::python::operators<(  boost::python::op_eq
-                                          | boost::python::op_ne)>());
-    py_code.def(NotImplemented, "__lt__");
-    py_code.def(NotImplemented, "__le__");
-    py_code.def(NotImplemented, "__gt__");
-    py_code.def(NotImplemented, "__ge__");
-
- -NotImplemented is a simple free function that (currently) has -to be provided by the user. For example:
-  boost::python::ref
-  NotImplemented(const code&, const code&) {
-    return
-    boost::python::ref(Py_NotImplemented, boost::python::ref::increment_count);
-  }

-

- Overview -

-

- Boost.Python 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, __init__ is defined by - - 
    my_class.def(boost::python::constructor<...>())
- - (see section "A Simple Example Using Boost.Python").

-

- __del__(self) -
- Called when the extension instance is about to be destroyed. For extension classes - not subclassed in Python, __del__ is always defined automatically by - means of the class' destructor. -
- __repr__(self) -
- Create a string representation from which the object can be - reconstructed. -
- __str__(self) -
- Create a string representation which is suitable for printing. -
- __lt__(self, other) -
- __le__(self, other) -
- __eq__(self, other) -
- __ne__(self, other) -
- __gt__(self, other) -
- __ge__(self, other) -
- Rich Comparison methods. - New in Python 2.1. - See Rich Comparisons. -
- __cmp__(self, other) -
- Three-way compare function. - See Rich Comparisons. -
- __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 Boost.Python 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 same basic technique used to expose - to_string() as __str__() above, and is covered in detail below. Boost.Python 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. That is, in C++ we can write: -

-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>());
-
- Boost.Python 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 called mod(): - -

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

- For automatic wrapping of the modulo function, operator%() would be needed. - Therefore, the mod()-functions must be wrapped manually. That is, we have - to export them explicitly with the Python special name "__mod__": - -

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

- The third form of mod() (with int as left operand) cannot - be wrapped directly. 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__" (standing for "reverse mod"): - -
-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. - -

Inplace Operators

-

- Boost.Python can also be used to expose inplace numeric operations - (i.e., += and so forth). These operators must be wrapped - manually, as described in the previous section. For example, suppose - the class BigNum has an operator+=: - -

-BigNum& operator+= (BigNum const& right);
-
- - This can be exposed by first writing a wrapper function: - -
-BigNum& iadd (BigNum& self, const BigNum& right)
-{
-  return self += right;
-}
-
- - and then exposing the wrapper with - -
-bignum_class.def(&iadd, "__iadd__");
-
- - - - -

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 types to a - common type before invoking the actual operator. Implementing good - coercion functions can be difficult if many type combinations must be - supported. -

- Boost.Python 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 Boost.Python automatically - ensures that the correct function is called in each case; there is no - need for user-defined coercion functions. To enable operator - overloading, Boost.Python 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 still define the "__coerce__" operator manually. 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: - -
-// this must be called before any use of automatic operator  
-// wrapping or a call to some_class.def_standard_coerce()
-some_class.def(&custom_coerce, "__coerce__");
-
- - Note that the standard coercion (defined by use of automatic - operator wrapping on a class_builder or a call to - class_builder::def_standard_coerce()) will never be applied if - a custom coercion function has been registered. Therefore, in - your coercion function you should call - -
-boost::python::standard_coerce(left, right);
-
- - for all cases that you don't want to handle yourself. - -

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& modulus);
-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's the third argument. These functions - must be presented to Boost.Python such that that the BigNum - argument appears in first position: - -
-BigNum rpower(BigNum const& second, int first, int modulus)
-{
-    return power(first, second, modulus);
-}
-
-BigNum rrpower(BigNum const& modulus, int first, int second)
-{
-    return power(first, second, modulus);
-}
-
- -

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; ++i)
-
- -

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'

Customized Attribute Access

- -

- Just like built-in Python classes, Boost.Python 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, Boost.Python checks the special names - -

    -
  • - __getattr__<name>__ -
  • - __setattr__<name>__ -
  • - __delattr__<name>__ -
- - 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(AnyBoost.PythonExtensionClass):
-...    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 -

-

- Boost.Python 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<>: -

    -
  • - def_getter(pointer-to-member, name) // - read access to the member via attribute name -
  • - def_setter(pointer-to-member, name) // - write access to the member via attribute name -
  • - def_readonly(pointer-to-member, name) - // read-only access to the member via attribute name -
  • - def_read_write(pointer-to-member, - name) // read/write access to the member via attribute - name -
-

- 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". -

- Boost.Python 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. -

Private names reached -from M's globals are skipped, but all names reached from M.__test__ are -searched. - -By default, a name is considered to be private if it begins with an -underscore (like "_my_func") but doesn't both begin and end with (at -least) two underscores (like "__init__"). You can change the default -by passing your own "isprivate" function to testmod. - -If you want to test docstrings in objects with private names too, stuff -them into an M.__test__ dict, or see ADVANCED USAGE below (e.g., pass your -own isprivate function to Tester's constructor, or call the rundoc method -of a Tester obj). - -Warning: imports can cause trouble; e.g., if you do - -from XYZ import XYZclass - -then XYZclass is a name in M.__dict__ too, and doctest has no way to -know that XYZclass wasn't *defined* in M. So it may try to execute the -examples in XYZclass's docstring, and those in turn may require a -different set of globals to work correctly. I prefer to do "import *"- -friendly imports, a la - -import XYY -_XYZclass = XYZ.XYZclass -del XYZ - -and then the leading underscore stops testmod from going nuts. You may -prefer the method in the next section. - - -WHAT'S THE EXECUTION CONTEXT? - -By default, each time testmod finds a docstring to test, it uses a -*copy* of M's globals (so that running tests on a module doesn't change -the module's real globals, and so that one test in M can't leave behind -crumbs that accidentally allow another test to work). This means -examples can freely use any names defined at top-level in M. It also -means that sloppy imports (see above) can cause examples in external -docstrings to use globals inappropriate for them. - -You can force use of your own dict as the execution context by passing -"globs=your_dict" to testmod instead. Presumably this would be a copy -of M.__dict__ merged with the globals from other imported modules. - - -WHAT IF I WANT TO TEST A WHOLE PACKAGE? - -Piece o' cake, provided the modules do their testing from docstrings. -Here's the test.python I use for the world's most elaborate Rational/ -floating-base-conversion pkg (which I'll distribute some day): - -from Rational import Cvt -from Rational import Format -from Rational import machprec -from Rational import Rat -from Rational import Round -from Rational import utils - -modules = (Cvt, - Format, - machprec, - Rat, - Round, - utils) - -def _test(): - import doctest - import sys - verbose = "-v" in sys.argv - for mod in modules: - doctest.testmod(mod, verbose=verbose, report=0) - doctest.master.summarize() - -if __name__ == "__main__": - _test() - -IOW, it just runs testmod on all the pkg modules. testmod remembers the -names and outcomes (# of failures, # of tries) for each item it's seen, -and passing "report=0" prevents it from printing a summary in verbose -mode. Instead, the summary is delayed until all modules have been -tested, and then "doctest.master.summarize()" forces the summary at the -end. - -So this is very nice in practice: each module can be tested individually -with almost no work beyond writing up docstring examples, and collections -of modules can be tested too as a unit with no more work than the above. - - -WHAT ABOUT EXCEPTIONS? - -No problem, as long as the only output generated by the example is the -traceback itself. For example: - - >>> 1/0 - Traceback (innermost last): - File "", line 1, in ? - ZeroDivisionError: integer division or modulo - >>> - -Note that only the exception type and value are compared (specifically, -only the last line in the traceback). - - -ADVANCED USAGE - -doctest.testmod() captures the testing policy I find most useful most -often. You may want other policies. - -testmod() actually creates a local obj of class doctest.Tester, -runs appropriate methods of that class, and merges the results into -global Tester obj doctest.master. - -You can create your own instances of doctest.Tester, and so build your -own policies, or even run methods of doctest.master directly. See -doctest.Tester.__doc__ for details. - - -SO WHAT DOES A DOCSTRING EXAMPLE LOOK LIKE ALREADY!? - -Oh ya. It's easy! In most cases a copy-and-paste of an interactive -console session works fine -- just make sure the leading whitespace -is rigidly consistent (you can mix tabs and spaces if you're too lazy -to do it right, but doctest is not in the business of guessing what -you think a tab means). - - >>> # comments are ignored - >>> x = 12 - >>> x - 12 - >>> if x == 13: - ... print "yes" - ... else: - ... print "no" - ... print "NO" - ... print "NO!!!" - ... - no - NO - NO!!! - >>> - -Any expected output must immediately follow the final ">>>" or "..." -line containing the code, and the expected output (if any) extends -to the next ">>>" or all-whitespace line. That's it. - -Bummers: - -+ Expected output cannot contain an all-whitespace line, since such a - line is taken to signal the end of expected output. - -+ Output to stdout is captured, but not output to stderr (exception - tracebacks are captured via a different means). - -+ If you continue a line via backslashing in an interactive session, - or for any other reason use a backslash, you need to double the - backslash in the docstring version. This is simply because you're - in a string, and so the backslash must be escaped for it to survive - intact. Like: - ->>> if "yes" == \\ -... "y" + \\ -... "es": # in the source code you'll see the doubled backslashes -... print 'yes' -yes - -The starting column doesn't matter: - ->>> assert "Easy!" - >>> import math - >>> math.floor(1.9) - 1.0 - -and as many leading whitespace characters are stripped from the expected -output as appeared in the initial ">>>" line that triggered it. - -If you execute this very file, the examples above will be found and -executed, leading to this output in verbose mode: - -Running doctest.__doc__ -Trying: 1/0 -Expecting: -Traceback (innermost last): - File "", line 1, in ? -ZeroDivisionError: integer division or modulo -ok -Trying: x = 12 -Expecting: nothing -ok -Trying: x -Expecting: 12 -ok -Trying: -if x == 13: - print "yes" -else: - print "no" - print "NO" - print "NO!!!" -Expecting: -no -NO -NO!!! -ok -... and a bunch more like that, with this summary at the end: - -5 items had no tests: - doctest.Tester.__init__ - doctest.Tester.run__test__ - doctest.Tester.summarize - doctest.run_docstring_examples - doctest.testmod -12 items passed all tests: - 8 tests in doctest - 6 tests in doctest.Tester - 10 tests in doctest.Tester.merge - 7 tests in doctest.Tester.rundict - 3 tests in doctest.Tester.rundoc - 3 tests in doctest.Tester.runstring - 2 tests in doctest.__test__._TestClass - 2 tests in doctest.__test__._TestClass.__init__ - 2 tests in doctest.__test__._TestClass.get - 1 tests in doctest.__test__._TestClass.square - 2 tests in doctest.__test__.string - 7 tests in doctest.is_private -53 tests in 17 items. -53 passed and 0 failed. -Test passed. -""" - -# 0,0,1 06-Mar-1999 -# initial version posted -# 0,0,2 06-Mar-1999 -# loosened parsing: -# cater to stinkin' tabs -# don't insist on a blank after PS2 prefix -# so trailing "...

Is it an - iterator? A pointer to a single element? An array? Is ownership being passed - to Python or is the pointer really just a reference? If the latter, what - happens when some C++ code deletes the referent. The only exception to this - rule is const char*, since it has a generally accepted interpretation (could - be trouble with some generic code, though!) - - If you have wrapped the Record class, you could add this to namespace py: - - PyObject* to_python(const Record* p) { - return to_python(*p); - } - - Of course, this will cause the Record class to be copied. If you can't live - with that (Record would have to be /really/ heavyweight to make this - worthwhile), you can follow one of these dangerous approaches: - - 1. Use the technique I described with dangerous_array in - http://www.egroups.com/message/boost/6196. You do not have to expose Record - explicitly in this case. Instead the class you expose will be more of a - Record_proxy - - 2. Wrap Record in the usual way, then add the following to namespace py: - - PyObject* to_python(const Record* p) - { - return ExtensionClass::ptr_to_python(const_cast(p)); - } - - This will cause the Record* 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-correctness issue: Const-correctness is completely - lost to Python anyway! - - 3. As above, but instead wrap const Record rather than plain Record. Then - you can avoid the const_cast, but you obviously can't def() any non-const - member functions of Record. - - Case 2: - - > I have yet another question. This is more a general wrapper question. - > Let me say that there is a function that returns a float* which most - > probably is an array. Similarly if I have a function that takes a - > float* as an argument, what is the best way of wrapping this? - - I think you have correctly perceived that it doesn't make sense for me to - automatically convert all pointers, since the ownership semantics are so - blurry. - - > 1) If the array is small it makes sense to convert it to either a - > tuple or list. What is the easiest way to do this?? I am looking - > for a way that makes one write the least code. :) - - How can you tell the length of the array from a single pointer? - Once you've answered that question, you can expose a wrapper function which - returns an instance of the py::Tuple or py::List class from objects.h. If - you are using a List, for example, you could write something like this: - - py::List wrap_f() - { - T* start = f(); - py::List x; - for (T* p = start; p != start + length_constant; ++p) - x.push_back(py::to_python(*p)); - return x; - } - - > 2) If the array is large it may not make sense to use a list/tuple - > esp. if the values are used for computationally intense programs. - - In this case you can do one of several somewhat dangerous things. Why - dangerous? Because python can not control the lifetime of the data, so the - data in the array may be destroyed or become invalid before the last - reference to it disappears. The basic approach is to make a small C++ class - which contains the pointer, and expose that: - - // UNTESTED - template - struct dangerous_array - { - dangerous_array(T* start, T* end) - : m_start(start), m_end(end) {} - - // exposed as "__len__" - std::size_t length() { - return m_end - m_start; - } - - // exposed as "__getitem__" - T get_item(std::size_t n) { - check_range(n); - return start[n]; - } - - // exposed as "__setitem__" if the array is mutable - void set_item(std::size_t n, const T& x) { - check_range(n); - start[n] = x; - } - private: - void check_range(std::size_t n) { - if (n >= m_end - m_start) { - PyErr_SetString(PyExc_IndexError, "array index out of range"); - throw py::ErrorAlreadySet; - } - } - T* m_start; - T* m_end; - }; - - A reasonably safe approach would be to make a wrapper function for each - function that returns a T*, and expose that instead. If you're too lazy and - you really like to live on the edge, though, you can write to_python(T*) in - terms of to_python(const dangerous_array&), and you'll automatically - convert all T* return values to a wrapped dangerous_array. - - > 3) For an arbitrary class "class_A", say, can py_cpp handle - > references to class_A &instance, or class_A *instance?? i.e. will it - > wrap function calls to such objects? This question is obviously - > related to the earlier questions. - - Yes, iff class_A has been exposed to python with a ClassWrapper. - See http://people.ne.mediaone.net/abrahams/downloads/under-the-hood.html for - a few details. - - raw C++ arrays - You could expose a function like this one to get the desired effect: - - #include - void set_len(UnitCell& x, py::Tuple tuple) - { - double len[3]; - for (std::size_t i =0; i < 3; ++i) - len[i] = py::from_python(tuple[i].get(), py::Type()); - x.set_len(len); - } - - Types that are already wrapped by other libraries - - It's not documented yet, but you should be able to use a raw PyObject* or a - py::Ptr as one parameter to your C++ function. Then you can manipulate it as - any other generic Python object. - - Alternatively, If the NTL gives you a C/C++ interface, you can also write - your own converter function: - - some_ntl_type& from_python(PyObject* p, py::Type) - { - // an Example implementation. Basically, you need - // to extract the NTL type from the PyObject*. - if (p->ob_type != NTL_long_type) { - PyErr_SetString(PyExc_TypeErr, "NTL long required"); - throw py::ArgumentError(); - } - return *static_cast(p); - } - - then the C++ functions you're wrapping can take a some_NTL_type& parameter - directly. - - "Thin converting wrappers" for constructors - - hijack some of the functionality - described in the section on Overridable Virtual Functions (even though you - don't have any virtual functions). I suggest this workaround: - - struct UnitCellWrapper : UnitCell - { - UnitCellWrapper(PyObject* self, py::Tuple x, py::Tuple y) - : UnitCell(from_python(x[1], py::Type()), - from_python(x[2], py::Type()), - from_python(x[3], py::Type()), - from_python(y[1], py::Type()), - from_python(y[2], py::Type()), - from_python(y[3], py::Type())) - {} - } - - py::ClassWrapper unit_cell_class; - unit_cell_class.def(py::Constructor()); - ... - - returning references to wrapped objects - - the importance of declaration order of ClassWrappers/ExtensionInstances - - out parameters and non-const pointers - - Calling back into Python: - // caveat: UNTESTED! - #include - #include - #include - #include - int main() - { - try { - py::Ptr module(PyImport_ImportModule("weapons")); - const int strength = 10; - const char* manufacturer = "Vordon Empire"; - py::Ptr a_blaster(py::Callback::call_method( - module.get(), "Blaster", strength, manufacturer)); - py::Callback::call_method(a_blaster.get(), "Fire"); - int old_strength = py::Callback::call_method(a_blaster.get(), "get_strength"); - py::Callback::call_method(a_blaster.get(), "set_strength", 5); - } - catch(...) - { - } - } - - Miscellaneous - About the vc6 project and the debug build - About doctest.py - -Boost remarks: - - > > One of us is completely nuts ;->.
