  Fixed intel-darwin unresolved symbols by changing the 
  wide integer type from unsigned int (which managles as
  a 'j') to an int (which mangles as an 'i').  This
  change makes intel-darwin generated code match the 
  darwin toolset generated code.
  
  Intel reports this won't be fixed in 10.1 because it's
  an ABI breanking chanage so we won't see this patched 
  until the 10.2 compilers.

either changing assert(...) or BOOST_ASSERT(...) to BOOST_TEST

    or adding "return boost::report_errors();" where it was clearly
    missing (and a pure bug, in anyone's code).

d78836b828 Fix lots of bugs in the numeric interface and tests.
Tests:
* Coerce a result to bool to deal with Python's new Bool type
* Better reporting of mismatches in expected and received results
* Remove bogus nullary y.astype() call
* Fix all uses of trace and diagonal so they don't cause errors
* Use appropriate typecodes
* Use doctest detailed API to run just the relevant tests
* Factor out error handling from macro

API:
* Added get_module_name() function to get current numeric module
* new_(x) now returns an array instead of object
* Fixed the signatures of the factory() family of functions
* Updated docs accordingly.

<p>The core of PolyBoRi is a C++ library, which provides
high-level data types for Boolean polynomials and monomials,
exponent vectors, as well as for the underlying polynomial
rings and subsets of the powerset of the Boolean variables. As
a unique approach, binary decision diagrams are used as
internal storage type for polynomial structures. On top of
this C++-library we provide a Python interface. This allows
parsing of complex polynomial systems, as well as sophisticated
and extendable strategies for Gr&ouml;bner basis computation.
Boost.Python has helped us to create this interface in a
very clean way.</p>

As you probably already know, objects in Python are reference-counted. Naturally,
the <tt class="literal">PyObject</tt>s of the Python/C API are also reference-counted.
There is a difference however. While the reference-counting is fully automatic
in Python, the Python/C API requires you to do it <a href="http://www.python.org/doc/current/api/refcounts.html" target="_top">by
hand</a>. This is messy and especially hard to get right in the presence
in Python, the Python<span class="emphasis"><em>C API requires you to do it [@http:</em></span>/www.python.org/doc/current/api/refcounts.html
by hand]. This is messy and especially hard to get right in the presence
of C++ exceptions. Fortunately Boost.Python provides the <a href="../../../../v2/handle.html" target="_top">handle</a>
and <a href="../../../../v2/object.html" target="_top">object</a> class templates to
automate the process.
</p>
<a name="using_the_interpreter.reference_counting_handles_and_objects"></a><h2>
<a name="id462914"></a>
Reference-counting handles and objects
</h2>
<p>
There are two ways in which a function in the Python/C API can return a
<tt class="literal">PyObject*</tt>: as a <span class="emphasis"><em>borrowed reference</em></span>
or as a <span class="emphasis"><em>new reference</em></span>. Which of these a function uses,
is listed in that function's documentation. The two require slightely different
approaches to reference-counting but both can be 'handled' by Boost.Python.
</p>
<p>
For a function returning a <span class="emphasis"><em>borrowed reference</em></span> we'll
have to tell the <tt class="literal">handle</tt> that the <tt class="literal">PyObject*</tt>
is borrowed with the aptly named <a href="../../../../v2/handle.html#borrowed-spec" target="_top">borrowed</a>
function. Two functions returning borrowed references are <a href="http://www.python.org/doc/current/api/importing.html#l2h-125" target="_top">PyImport_AddModule</a>
and <a href="http://www.python.org/doc/current/api/moduleObjects.html#l2h-594" target="_top">PyModule_GetDict</a>.
The former returns a reference to an already imported module, the latter
retrieves a module's namespace dictionary. Let's use them to retrieve the
namespace of the <tt class="literal"><span class="underline">_main</span>_</tt>
module:
</p>
<pre class="programlisting">
<span class="identifier">object</span> <span class="identifier">main_module</span><span class="special">((</span>
<span class="identifier">handle</span><span class="special">&lt;&gt;(</span><span class="identifier">borrowed</span><span class="special">(</span><a href="http://www.python.org/doc/current/api/importing.html#l2h-125" target="_top">PyImport_AddModule</a><span class="special">(</span><span class="string">"__main__"</span><span class="special">)))));</span>
<span class="identifier">object</span> <span class="identifier">main_namespace</span> <span class="special">=</span> <span class="identifier">main_module</span><span class="special">.</span><span class="identifier">attr</span><span class="special">(</span><span class="string">"__dict__"</span><span class="special">);</span>
</pre>
<p>
For a function returning a <span class="emphasis"><em>new reference</em></span> we can just
create a <tt class="literal">handle</tt> out of the raw <tt class="literal">PyObject*</tt>
without wrapping it in a call to borrowed. One such function that returns
a new reference is <a href="http://www.python.org/doc/current/api/veryhigh.html#l2h-55" target="_top">PyRun_String</a>
which we'll discuss in the next section.
</p>
<p class="blurb">
<span class="inlinemediaobject"><img src="../images/note.png" alt="note"></span> <span class="bold"><b>Handle is a class <span class="emphasis"><em>template</em></span>,
so why haven't we been using any template parameters?</b></span><br> <br>
<tt class="literal">handle</tt> has a single template parameter specifying the
type of the managed object. This type is <tt class="literal">PyObject</tt> 99%
of the time, so the parameter was defaulted to <tt class="literal">PyObject</tt>
for convenience. Therefore we can use the shorthand <tt class="literal">handle&lt;&gt;</tt>
instead of the longer, but equivalent, <tt class="literal">handle&lt;PyObject&gt;</tt>.

Running Python code
</h2>
<p>
To run Python code from C++ there is a family of functions in the API starting
with the PyRun prefix. You can find the full list of these functions <a href="http://www.python.org/doc/current/api/veryhigh.html" target="_top">here</a>. They
all work similarly so we will look at only one of them, namely:
Boost.python provides three related functions to run Python code from C++.

<a href="http://www.python.org/doc/current/api/veryhigh.html#l2h-55" target="_top">PyRun_String</a>
takes the code to execute as a null-terminated (C-style) string in its <tt class="literal">str</tt>
parameter. The function returns a new reference to a Python object. Which
object is returned depends on the <tt class="literal">start</tt> paramater.
eval evaluates the given expression and returns the resulting value. exec
executes the given code (typically a set of statements) returning the result,
and exec_file executes the code contained in the given file.
</p>
<p>
The <tt class="literal">start</tt> parameter is the start symbol from the Python
grammar to use for interpreting the code. The possible values are:

The <tt class="literal">globals</tt> and <tt class="literal">locals</tt> parameters are
Python dictionaries containing the globals and locals of the context in which

</p>
<p>
We have already seen how to get the <tt class="literal"><span class="underline">_main</span>_</tt>
module's namespace so let's run some Python code in it:
Boost.python provides a function to import a module:

<span class="string">"hello.write('Hello world!')\n"</span>
<span class="string">"hello.close()"</span>

<span class="identifier">object</span> <span class="identifier">import</span><span class="special">(</span><span class="identifier">str</span> <span class="identifier">name</span><span class="special">)</span>
</pre>
<p>
Because the Python/C API doesn't know anything about <tt class="literal">object</tt>s,
we used the object's <tt class="literal">ptr</tt> member function to retrieve the
<tt class="literal">PyObject*</tt>.
import imports a python module (potentially loading it into the running process
first), and returns it.
</p>
<p>
Let's import the <tt class="literal"><span class="underline">_main</span>_</tt>
module and run some Python code in its namespace:
</p>
<pre class="programlisting">
<span class="identifier">object</span> <span class="identifier">main_module</span> <span class="special">=</span> <span class="identifier">import</span><span class="special">(</span><span class="string">"__main__"</span><span class="special">);</span>

<span class="string">"hello.write('Hello world!')\n"</span>
<span class="string">"hello.close()"</span><span class="special">,</span>
<span class="identifier">main_namespace</span><span class="special">);</span>
</pre>
<p>
This should create a file called 'hello.txt' in the current directory containing
a phrase that is well-known in programming circles.
</p>
<p class="blurb">
<span class="inlinemediaobject"><img src="../images/note.png" alt="note"></span> <span class="bold"><b>Note</b></span> that we wrap

<p>
It's nice that <tt class="literal">handle</tt> manages the reference counting details
for us, but other than that it doesn't do much. Often we'd like to have a
more useful class to manipulate Python objects. But we have already seen
such a class above, and in the <a href="object.html" target="_top">previous section</a>:
the aptly named <tt class="literal">object</tt> class and it's derivatives. We've
already seen that they can be constructed from a <tt class="literal">handle</tt>.

this variable from the dictionary. Another way to achieve the same result
is to let <a href="http://www.python.org/doc/current/api/veryhigh.html#l2h-55" target="_top">PyRun_String</a>
return the result directly with <a href="http://www.python.org/doc/current/api/veryhigh.html#l2h-58" target="_top">Py_eval_input</a>:
is to use eval instead, which returns the result directly:

If an exception occurs in the execution of some Python code, the <a href="http://www.python.org/doc/current/api/veryhigh.html#l2h-55" target="_top">PyRun_String</a>
function returns a null pointer. Constructing a <tt class="literal">handle</tt>
out of this null pointer throws <a href="../../../../v2/errors.html#error_already_set-spec" target="_top">error_already_set</a>,
so basically, the Python exception is automatically translated into a C++
exception when using <tt class="literal">handle</tt>:

In this chapter, we'll look at Boost.Python powered functions in closer detail.
We shall see some facilities to make exposing C++ functions to Python safe
from potential pifalls such as dangling pointers and references. We shall also
see facilities that will make it even easier for us to expose C++ functions
that take advantage of C++ features such as overloading and default arguments.

A file called user-config.jam in your home directory is used to configure your
tools. In Windows, your home directory can be found by typing:
</p>
<pre class="programlisting">C:\Program Files\Microsoft Visual Studio .NET 2003\Common7\Tools\vsvars32.bat
<pre class="programlisting">ECHO %HOMEDRIVE%%HOMEPATH%
</pre>
<p>
Some environment variables will have to be setup for proper building of our
Python modules. Example:
into a command prompt window. Your file should at least have the rules for
your compiler and your python installation. A specific example of this on Windows
would be:
</p>
<pre class="programlisting">set PYTHON_ROOT=c:/dev/tools/python
set PYTHON_VERSION=2.2
<pre class="programlisting"># MSVC configuration
using msvc : 8.0 ;
# Python configuration
using python : 2.4 : C:/dev/tools<span class="emphasis"><em>Python</em></span> ;
</pre>
<p>
The above assumes that the Python installation is in <tt class="literal">c:/dev/tools/python</tt>
and that we are using Python version 2.2. You'll have to tweak these appropriately.
</p>
<p class="blurb">
<span class="inlinemediaobject"><img src="../images/tip.png" alt="tip"></span> Be sure not to include a third number, e.g. <span class="bold"><b>not</b></span> "2.2.1", even if that's the version you
have.
</p>
<p>
Take note that you may also do that through the Jamrules file we put in our
project as detailed above. The file has <a href="../../../../../example/tutorial/Jamrules" target="_top">detailed
instructions</a> you can follow.
The first rule tells Bjam to use the MSVC 8.0 compiler and associated tools.
The second rule provides information on Python, its version and where it is
located. The above assumes that the Python installation is in <tt class="literal">C:/dev/tools/Python/</tt>.
If you have one fairly "standard" python installation for your platform,
you might not need to do this.
</p>
<p>
Now we are ready... Be sure to <tt class="literal">cd</tt> to <tt class="literal">libs/python/example/tutorial</tt>
where the tutorial <tt class="literal">"hello.cpp"</tt> and the <tt class="literal">"Jamfile"</tt>
where the tutorial <tt class="literal">"hello.cpp"</tt> and the <tt class="literal">"Jamroot"</tt>
is situated.
</p>
<p>
Finally:
</p>

<span class="identifier">bjam</span>
</pre>
<p>
We are again assuming that we are using Microsoft Visual C++ version 7.1. If
not, then you will have to specify the appropriate tool. See <a href="../../../../../../../tools/build/index.html" target="_top">Building
Boost Libraries</a> for further details.
</p>
<p>
It should be building now:
</p>
<pre class="programlisting">cd C:\dev\boost\libs\python\example\tutorial

bjam
...patience...
...found 1703 targets...
...updating 40 targets...
...found 1101 targets...
...updating 35 targets...

<p>
And so on... Finally:
</p>
<pre class="programlisting">Creating library bin\boost\libs\python\build\boost_python.dll\vc-7_1\debug\th

<p>

run the Python program.

<tt class="literal">boost_python.dll</tt> and <tt class="literal">hello.pyd</tt> can be
found somewhere in your project's <tt class="literal">bin</tt> directory. After a
successful build, you make it possible for the system to find boost_python.dll

or some other variable on *nix and with PATH on Windows) and for Python to
find the hello module (Done with PYTHONPATH on all systems.)

[section Using the interpreter]
As you probably already know, objects in Python are reference-counted.
Naturally, the [^PyObject]s of the Python/C API are also reference-counted.
Naturally, the [^PyObject]s of the Python\/C API are also reference-counted.
There is a difference however. While the reference-counting is fully
automatic in Python, the Python/C API requires you to do it
automatic in Python, the Python\/C API requires you to do it
[@http://www.python.org/doc/current/api/refcounts.html by hand]. This is
messy and especially hard to get right in the presence of C++ exceptions.
Fortunately Boost.Python provides the [@../../../v2/handle.html handle] and
[@../../../v2/object.html object] class templates to automate the process.
[h2 Reference-counting handles and objects]
There are two ways in which a function in the Python/C API can return a
[^PyObject*]: as a ['borrowed reference] or as a ['new reference]. Which of
these a function uses, is listed in that function's documentation. The two
require slightely different approaches to reference-counting but both can
be 'handled' by Boost.Python.
For a function returning a ['borrowed reference] we'll have to tell the
[^handle] that the [^PyObject*] is borrowed with the aptly named
[@../../../v2/handle.html#borrowed-spec borrowed] function. Two functions
returning borrowed references are PyImport_AddModule and PyModule_GetDict.
The former returns a reference to an already imported module, the latter
retrieves a module's namespace dictionary. Let's use them to retrieve the
namespace of the [^__main__] module:
object main_module((
handle<>(borrowed(PyImport_AddModule("__main__")))));
object main_namespace = main_module.attr("__dict__");
For a function returning a ['new reference] we can just create a [^handle]
out of the raw [^PyObject*] without wrapping it in a call to borrowed. One
such function that returns a new reference is PyRun_String which we'll
discuss in the next section.
[blurb __note__ [*Handle is a class ['template], so why haven't we been using any template parameters?]\n
\n
[^handle] has a single template parameter specifying the type of the managed object. This type is [^PyObject] 99% of the time, so the parameter was defaulted to [^PyObject] for convenience. Therefore we can use the shorthand [^handle<>] instead of the longer, but equivalent, [^handle<PyObject>].

[h2 Running Python code]
To run Python code from C++ there is a family of functions in the API
starting with the PyRun prefix. You can find the full list of these
functions [@http://www.python.org/doc/current/api/veryhigh.html here]. They
all work similarly so we will look at only one of them, namely:
Boost.python provides three related functions to run Python code from C++.
PyObject* PyRun_String(char *str, int start, PyObject *globals, PyObject *locals)
object eval(str expression, object globals = object(), object locals = object())
object exec(str code, object globals = object(), object locals = object())
object exec_file(str filename, object globals = object(), object locals = object())
PyRun_String takes the code to execute as a null-terminated (C-style)
string in its [^str] parameter. The function returns a new reference to a
Python object. Which object is returned depends on the [^start] paramater.
eval evaluates the given expression and returns the resulting value.
exec executes the given code (typically a set of statements) returning the result,
and exec_file executes the code contained in the given file.
The [^start] parameter is the start symbol from the Python grammar to use
for interpreting the code. The possible values are:
[table Start symbols
[[Py_eval_input] [for interpreting isolated expressions]]
[[Py_file_input] [for interpreting sequences of statements]]
[[Py_single_input] [for interpreting a single statement]]
]
When using Py_eval_input, the input string must contain a single expression
and its result is returned. When using Py_file_input, the string can
contain an abitrary number of statements and None is returned.
Py_single_input works in the same way as Py_file_input but only accepts a
single statement.
Lastly, the [^globals] and [^locals] parameters are Python dictionaries
The [^globals] and [^locals] parameters are Python dictionaries
containing the globals and locals of the context in which to run the code.
For most intents and purposes you can use the namespace dictionary of the
[^__main__] module for both parameters.
We have already seen how to get the [^__main__] module's namespace so let's
run some Python code in it:
Boost.python provides a function to import a module:
object main_module((
handle<>(borrowed(PyImport_AddModule("__main__")))));
object import(str name)
import imports a python module (potentially loading it into the running process
first), and returns it.
Let's import the [^__main__] module and run some Python code in its namespace:
object main_module = import("__main__");
object main_namespace = main_module.attr("__dict__");
handle<> ignored((PyRun_String(
"hello = file('hello.txt', 'w')\n"
"hello.write('Hello world!')\n"
"hello.close()"
, Py_file_input
, main_namespace.ptr()
, main_namespace.ptr())
));
Because the Python/C API doesn't know anything about [^object]s, we used
the object's [^ptr] member function to retrieve the [^PyObject*].
object ignored = exec("hello = file('hello.txt', 'w')\n"
"hello.write('Hello world!')\n"
"hello.close()",
main_namespace);
This should create a file called 'hello.txt' in the current directory
containing a phrase that is well-known in programming circles.
[blurb
__note__ [*Note] that we wrap the return value of PyRun_String in a
(nameless) [^handle] even though we are not interested in it. If we didn't
do this, the the returned object would be kept alive unnecessarily. Unless
you want to be a Dr. Frankenstein, always wrap [^PyObject*]s in [^handle]s.
]
[h2 Manipulating Python objects]
[h2 Beyond handles]
It's nice that [^handle] manages the reference counting details for us, but
other than that it doesn't do much. Often we'd like to have a more useful
class to manipulate Python objects. But we have already seen such a class
above, and in the [@python/object.html previous section]: the aptly
named [^object] class and it's derivatives. We've already seen that they
can be constructed from a [^handle]. The following examples should further
illustrate this fact:
object main_module((
handle<>(borrowed(PyImport_AddModule("__main__")))));
Often we'd like to have a class to manipulate Python objects.
But we have already seen such a class above, and in the
[@python/object.html previous section]: the aptly named [^object] class
and its derivatives. We've already seen that they can be constructed from
a [^handle]. The following examples should further illustrate this fact:
object main_module = import("__main__");
object main_namespace = main_module.attr("__dict__");
handle<> ignored((PyRun_String(
"result = 5 ** 2"
, Py_file_input
, main_namespace.ptr()
, main_namespace.ptr())
));
object ignored = exec("result = 5 ** 2", main_namespace);
int five_squared = extract<int>(main_namespace["result"]);
Here we create a dictionary object for the [^__main__] module's namespace.
Then we assign 5 squared to the result variable and read this variable from
the dictionary. Another way to achieve the same result is to let
PyRun_String return the result directly with Py_eval_input:
object result((handle<>(
PyRun_String("5 ** 2"
, Py_eval_input
, main_namespace.ptr()
, main_namespace.ptr()))
));
the dictionary. Another way to achieve the same result is to use eval instead,
which returns the result directly:
object result = eval("5 ** 2");
int five_squared = extract<int>(result);
[blurb
__note__ [*Note] that [^object]'s member function to return the wrapped
[^PyObject*] is called [^ptr] instead of [^get]. This makes sense if you
take into account the different functions that [^object] and [^handle]
perform.
]
[h2 Exception handling]
If an exception occurs in the execution of some Python code, the PyRun_String
function returns a null pointer. Constructing a [^handle] out of this null
pointer throws [@../../../v2/errors.html#error_already_set-spec error_already_set],
so basically, the Python exception is automatically translated into a
C++ exception when using [^handle]:
If an exception occurs in the evaluation of the python expression,
[@../../../v2/errors.html#error_already_set-spec error_already_set] is thrown:
try
{
object result((handle<>(PyRun_String(
"5/0"
, Py_eval_input
, main_namespace.ptr()
, main_namespace.ptr()))
));
object result = eval("5/0");
// execution will never get here:
int five_divided_by_zero = extract<int>(result);
}

<h2><a name="introduction" id=
"introduction"></a>Introduction</h2>
<p>Boost.Python supports docstrings with automatic
appending of Pythonic and C++ signatures. This feature is implemented
by <code>class function_doc_signature_generator</code>
The class uses all of the overloads, supplied arg names and default values, as well as
the user-defined docstrings, to generate documentation for a given function.</p>
<h2><a name="classes" id="classes"></a>Classes</h2>
<h3><a name="function_doc_signature_generator-spec" id=
"function_doc_signature_generator-spec"></a>Class
<code>function_doc_signature_generator</code></h3>
<p>
The class has only one public function which returns a list of strings documenting the
overloads of a function.

When an instance of a Boost.Python extension class is pickled, the
pickler tests if the instance has a <tt>__getinitargs__</tt> 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.
At the user level, the Boost.Python pickle interface involves three special
methods:
<p>If <tt>__getinitargs__</tt> is not defined, <tt>pickle.load</tt>
will call the constructor (<tt>__init__</tt>) without arguments;

<h2><a name="introduction" id=
"introduction"></a>Introduction</h2>
<p>To support Pythonic signatures the converters should supply a <code>get_pytype</code> function
returning a pointer to the associated <code>PyTypeObject</code>. See for example
<a href="ResultConverter.html#ResultConverter-concept">ResultConverter</a> or
<a href="to_python_converter.html#to_python_converter-spec">to_python_converter</a>.
The classes in this header file are meant to be used when implmenting <code>get_pytype</code>.
There are also <code>_direct</code> versions of the templates of <code>class T</code> which
should be used with undecorated type parameter, expected to be in the conversion registry when the module loads.
</p>
<h2><a name="classes" id="classes"></a>Classes</h2>
<h3><a name="wrap_pytype-spec" id=
"wrap_pytype-spec"></a>Class
<code>wrap_pytype</code></h3>
<p>
This template generates a static <code>get_pytype</code> member returning the template parameter.
</p>
<h4><a name="wrap_pytype-spec-synopsis" id=
"wrap_pytype-spec-synopsis"></a>Class
<code>wrap_pytype</code> synopsis</h4>
<pre>
namespace boost { namespace python { namespace converter{
template &lt; PyTypeObject const *pytype &gt;
class wrap_pytype
{
public:
static PyTypeObject const *get_pytype(){return pytype; }
};
}}}
</pre>
<h3><a name="registered_pytype-spec" id=
"registered_pytype-spec"></a>Class
<code>registered_pytype</code></h3>
<p>
This template should be used with template parameters which are (possibly decorated)
types exported to python using <a href="class.html"><code>class_</code></a>.
The generated a static <code>get_pytype</code> member
returns the corresponding python type.
</p>
<h4><a name="registered_pytype-spec-synopsis" id=
"registered_pytype-spec-synopsis"></a>Class
<code>registered_pytype</code> synopsis</h4>
<pre>
namespace boost { namespace python { namespace converter{
template &lt; class T &gt;
class registered_pytype
{
public:
static PyTypeObject const *get_pytype();
};
}}}
</pre>
<h3><a name="expected_from_python_type-spec" id=
"expected_from_python_type-spec"></a>Class
<code>expected_from_python_type</code></h3>
<p>
This template generates a static <code>get_pytype</code> member which inspects the registered
<code>from_python</code> converters for the type <code>T</code> and returns a matching python type.
</p>
<h4><a name="expected_from_python_type-spec-synopsis" id=
"expected_from_python_type-spec-synopsis"></a>Class
<code>expected_from_python_type</code> synopsis</h4>
<pre>
namespace boost { namespace python { namespace converter{
template &lt; class T &gt;
class expected_from_python_type
{
public:
static PyTypeObject const *get_pytype();
};
}}}
</pre>
<h3><a name="to_python_target_type-spec" id=
"to_python_target_type-spec"></a>Class
<code>to_python_target_type</code></h3>
<p>
This template generates a static <code>get_pytype</code> member returning the
python type to which T can be converted.
</p>
<h4><a name="to_python_target_type-spec-synopsis" id=
"to_python_target_type-spec-synopsis"></a>Class
<code>to_python_target_type</code> synopsis</h4>
<pre>
namespace boost { namespace python { namespace converter{
template &lt; class T &gt;
class to_python_target_type
{
public:
static PyTypeObject const *get_pytype();
};
}}}
</pre>
<h2><a name="examples" id="examples"></a>Examples</h2>
This example presumes that someone has implemented the standard <a href=
"http://www.python.org/doc/2.2/ext/dnt-basics.html">noddy example
module</a> from the Python documentation, and placed the corresponding
declarations in <code>"noddy.h"</code>. Because
<code>noddy_NoddyObject</code> is the ultimate trivial extension type,
the example is a bit contrived: it wraps a function for which all
information is contained in the <i>type</i> of its return value.
<h3>C++ module definition</h3>
<pre>
#include &lt;boost/python/reference.hpp&gt;
#include &lt;boost/python/module.hpp&gt;
#include "noddy.h"
struct tag {};
tag make_tag() { return tag(); }
using namespace boost::python;
struct tag_to_noddy
#if defined BOOST_PYTHON_SUPPORTS_PY_SIGNATURES //unnecessary overhead if py signatures are not supported
: wrap_pytype<&amp;noddy_NoddyType> //inherits get_pytype from wrap_pytype
#endif
{
static PyObject* convert(tag const&amp; x)
{
return PyObject_New(noddy_NoddyObject, &amp;noddy_NoddyType);
}
};
BOOST_PYTHON_MODULE(to_python_converter)
{
def("make_tag", make_tag);
to_python_converter&lt;tag, tag_to_noddy
#if defined BOOST_PYTHON_SUPPORTS_PY_SIGNATURES //invalid if py signatures are not supported
, true
#endif
&gt;(); //"true" because tag_to_noddy has member get_pytype
}
</pre>
<p>The following example registers to and from python converters using the templates
<code>expected_from_python_type</code> and <code>to_pyhton_target_type</code>.
