0dcd40da74 Add Boost.Build support for the Git modular layout, using links to to new header locations, thus preventing breakage to vast amounts of user code and build setups. Being added to SVN so that changes will automatically propagate to Git and modular Boost. Thanks to Steven Watanabe, Jürgen Hunold, Vladimir Prus, and Bjørn Roald for developing this patch. Steven in particular conceived the approach and did the initial implementation, which was further refined by the other contributors.

ccf40a29c1 Correct testing bugs:
either changing assert(...) or BOOST_ASSERT(...) to BOOST_TEST
    (in my code only)

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

    or changing BOOST_TEST to BOOST_CHECK where the integer library
    was clearly using Boost.Test and not returning report_errors().

<!-- The keyword tags are specified as an `MPL Sequence`_, using the

signature is also specifid as an `MPL sequence`_ of parameter
types. Additionally, ``boost::parameter::python::function`` and

We will take a closer look at how this is done in the tutorial section below.</p>
<!-- The last two sentences are terribly vague. Which namespace is -->
<!-- ``function`` in? Isn't the return type always needed? What -->
<!-- else are we going to do other than pass these sequences to -->

</div>
<div class="section" id="tutorial">
<h1><a class="toc-backref" href="#id8">Tutorial</a></h1>
<p>In this section we will outline the steps needed to bind a simple
Boost.Parameter-enabled member function to Python. Knowledge of the
Boost.Parameter <a class="reference external" href="index.html">macros</a> are required to understand this section.</p>
<p>The class and member function we are interested in binding looks
like this:</p>
<pre class="literal-block">
#include &lt;boost/parameter/keyword.hpp&gt;
#include &lt;boost/parameter/preprocessor.hpp&gt;
#include &lt;boost/parameter/python.hpp&gt;
#include &lt;boost/python.hpp&gt;
// First the keywords
BOOST_PARAMETER_KEYWORD(tag, title)
BOOST_PARAMETER_KEYWORD(tag, width)
BOOST_PARAMETER_KEYWORD(tag, height)
class window
{
public:
BOOST_PARAMETER_MEMBER_FUNCTION(
(void), open, tag,
(required (title, (std::string)))
(optional (width, (unsigned), 400)
(height, (unsigned), 400))
)
{
<em>… function implementation …</em>
}
};
</pre>
<!-- @example.prepend('#include <cassert>') -->
<!-- @example.replace_emphasis('''
assert(title == "foo");
assert(height == 20);
assert(width == 400);
''') -->
<p>It defines a set of overloaded member functions called <tt class="docutils literal">open</tt> with one
required parameter and two optional ones. To bind this member function to
Python we use the binding utility <tt class="docutils literal"><span class="pre">boost::parameter::python::function</span></tt>.
<tt class="docutils literal"><span class="pre">boost::parameter::python::function</span></tt> is a <a class="reference external" href="../../../python/doc/v2/def_visitor.html"><tt class="docutils literal">def_visitor</tt></a> that we'll instantiate
and pass to <tt class="docutils literal"><span class="pre">boost::python::class_::def()</span></tt>.</p>
<p>To use <tt class="docutils literal"><span class="pre">boost::parameter::python::function</span></tt> we first need to define
a class with forwarding overloads. This is needed because <tt class="docutils literal"><span class="pre">window::open()</span></tt>
is a function template, so we can't refer to it in any other way.</p>
<pre class="literal-block">
struct open_fwd
{
template &lt;class A0, class A1, class A2&gt;
void operator()(
boost::type&lt;void&gt;, window&amp; self
, A0 const&amp; a0, A1 const&amp; a1, A2 const&amp; a2
)
{
self.open(a0, a1, a2);
}
};
</pre>
<p>The first parameter, <tt class="docutils literal"><span class="pre">boost::type&lt;void&gt;</span></tt>, tells the forwarding overload
what the return type should be. In this case we know that it's always void
but in some cases, when we are exporting several specializations of a
Boost.Parameter-enabled template, we need to use that parameter to
deduce the return type.</p>
<p><tt class="docutils literal"><span class="pre">window::open()</span></tt> takes a total of 3 parameters, so the forwarding function
needs to take three parameters as well.</p>
<div class="note">
<p class="first admonition-title">Note</p>
<p class="last">We only need one overload in the forwarding class, despite the
fact that there are two optional parameters. There are special
circumstances when several overload are needed; see
<a class="reference internal" href="#special-keywords">special keywords</a>.</p>
</div>
<p>Next we'll define the module and export the class:</p>
<pre class="literal-block">
BOOST_PYTHON_MODULE(my_module)
{
using namespace boost::python;
namespace py = boost::parameter::python;
namespace mpl = boost::mpl;
class_&lt;window&gt;(&quot;window&quot;)
.def(
&quot;open&quot;, py::function&lt;
open_fwd
, mpl::vector&lt;
void
, tag::title(std::string)
, tag::width*(unsigned)
, tag::height*(unsigned)
&gt;
&gt;()
);
}
</pre>
<!-- @jam_prefix.append('import python ;') -->
<!-- @jam_prefix.append('stage . : my_module /boost/python//boost_python ;') -->
<!-- @my_module = build(
output = 'my_module'
, target_rule = 'python-extension'
, input = '/boost/python//boost_python'
, howmany = 'all'
) -->
<!-- @del jam_prefix[:] -->
<p><tt class="docutils literal"><span class="pre">py::function</span></tt> is passed two parameters. The first one is the class with
forwarding overloads that we defined earlier. The second one is an <a class="reference external" href="../../../mpl/doc/refmanual/sequences.html">MPL
Sequence</a> with the keyword tag types and argument types for the function
specified as function types. The pointer syntax used in <tt class="docutils literal"><span class="pre">tag::width*</span></tt> and
<tt class="docutils literal"><span class="pre">tag::height*</span></tt> means that the parameter is optional. The first element of
the <a class="reference external" href="../../../mpl/doc/refmanual/sequences.html">MPL Sequence</a> is the return type of the function, in this case <tt class="docutils literal">void</tt>,
which is passed as the first argument to <tt class="docutils literal">operator()</tt> in the forwarding
class.</p>
<!-- The
pointer syntax means that the parameter is optional, so in this case
``width`` and ``height`` are optional parameters. The third parameter
is an `MPL Sequence`_ with the desired function signature. The return type comes first, and
then the parameter types:
.. parsed-literal::
mpl::vector<void, std::string, unsigned, unsigned>
*return type* *title* *width* *height*
.. @ignore() -->
<p>That's it! This class can now be used in Python with the expected syntax:</p>
<pre class="literal-block">
&gt;&gt;&gt; w = my_module.window()
&gt;&gt;&gt; w.open(title = &quot;foo&quot;, height = 20)
</pre>
<!-- @example.prepend('import my_module') -->
<!-- @run_python(module_path = my_module) -->
<!-- Sorry to say this at such a late date, but this syntax really -->
<!-- strikes me as cumbersome. Couldn't we do something like:
class_<window>("window")
.def(
"open",
(void (*)(
tag::title(std::string),
tag::width*(unsigned),
tag::height*(unsigned))
)0
);
or at least:
class_<window>("window")
.def(
"open",
mpl::vector<
void,
tag::title(std::string),
tag::width*(unsigned),
tag::height*(unsigned)
>()
);
assuming, that is, that we will have to repeat the tags (yes,
users of broken compilers will have to give us function pointer
types instead). -->
</div>

<p>A <span class="concept">ParameterSpec</span> is a function type <tt class="docutils literal">K(T)</tt> that describes both the keyword tag,
<tt class="docutils literal">K</tt>, and the argument type, <tt class="docutils literal">T</tt>, for a parameter.</p>

<li><strong>or</strong>, a <em>special</em> keyword of the form <tt class="docutils literal">Tag**</tt></li>
</ul>
<p>where <tt class="docutils literal">Tag</tt> is a keyword tag type, as used in a specialization

<p>The <strong>arity range</strong> for an <a class="reference external" href="../../../mpl/doc/refmanual/sequences.html">MPL Sequence</a> of <span class="concept">ParameterSpec</span>'s is

the <strong>arity range</strong> of <tt class="docutils literal"><span class="pre">mpl::vector2&lt;x(int),y*(int)&gt;</span></tt> is <tt class="docutils literal">[2,2]</tt> and the

</div>
<div class="section" id="special-keywords">
<h1><a class="toc-backref" href="#id10"><em>special</em> keywords</a></h1>
<p>Sometimes it is desirable to have a default value for a parameter that differ
in type from the parameter. This technique is useful for doing simple tag-dispatching
based on the presence of a parameter. For example:</p>
<!-- An example_ of this is given in the Boost.Parameter
docs. The example uses a different technique, but could also have been written like this: -->
<pre class="literal-block">
namespace core
{
template &lt;class ArgumentPack&gt;
void dfs_dispatch(ArgumentPack const&amp; args, mpl::false_)
{
<em>…compute and use default color map…</em>
}
template &lt;class ArgumentPack, class ColorMap&gt;
void dfs_dispatch(ArgumentPack const&amp; args, ColorMap colormap)
{
<em>…use colormap…</em>
}
}
template &lt;class ArgumentPack&gt;
void depth_first_search(ArgumentPack const&amp; args)
{
core::dfs_dispatch(args, args[color | mpl::false_()]);
}
</pre>
<!-- @example.prepend('''
#include <boost/parameter/keyword.hpp>
#include <boost/parameter/parameters.hpp>
#include <boost/mpl/bool.hpp>
#include <cassert>
BOOST_PARAMETER_KEYWORD(tag, color);
typedef boost::parameter::parameters<tag::color> params;
namespace mpl = boost::mpl;
''') -->
<!-- @example.replace_emphasis('''

<!-- @example.replace_emphasis('''

<!-- @example.append('''
int main()
{
depth_first_search(params()());
depth_first_search(params()(color = 0));
}''') -->
<!-- @build() -->
<!-- .. _example: index.html#dispatching-based-on-the-presence-of-a-default -->
<p>In the above example the type of the default for <tt class="docutils literal">color</tt> is <tt class="docutils literal"><span class="pre">mpl::false_</span></tt>, a
type that is distinct from any color map that the user might supply.</p>
<p>When binding the case outlined above, the default type for <tt class="docutils literal">color</tt> will not
be convertible to the parameter type. Therefore we need to tag the <tt class="docutils literal">color</tt>
keyword as a <em>special</em> keyword. This is done by specifying the tag as
<tt class="docutils literal"><span class="pre">tag::color**</span></tt> when binding the function (see <a class="reference internal" href="#concept-parameterspec">concept ParameterSpec</a> for
more details on the tagging). By doing this we tell the binding functions that
it needs to generate two overloads, one with the <tt class="docutils literal">color</tt> parameter present
and one without. Had there been two <em>special</em> keywords, four overloads would
need to be generated. The number of generated overloads is equal to 2<sup>N</sup>, where <tt class="docutils literal">N</tt> is the number of <em>special</em> keywords.</p>

Introduction
------------
``boost/parameter/python.hpp`` introduces a group of |def_visitors|_ that can
be used to easily expose Boost.Parameter-enabled member functions to Python with
Boost.Python. It also provides a function template ``def()`` that can be used
to expose Boost.Parameter-enabled free functions.
.. |def_visitor| replace:: ``def_visitor``
.. |def_visitors| replace:: ``def_visitors``
.. _def_visitor: def_visitors_
.. _def_visitors: ../../../python/doc/v2/def_visitor.html
When binding a Boost.Parameter enabled function, the keyword tags
must be specified. Additionally, because Boost.Parameter enabled
functions are templates, the desired function signature must be
specified.
.. The keyword tags are specified as an `MPL Sequence`_, using the
pointer qualifications described in |ParameterSpec|_ below. The
signature is also specifid as an `MPL sequence`_ of parameter
types. Additionally, ``boost::parameter::python::function`` and
``boost::parameter::python::def`` requires a class with forwarding
overloads. We will take a closer look at how this is done in the
tutorial section below.
The keyword tags and associated argument types are specified as an `MPL
Sequence`_, using the function type syntax described in |ParameterSpec|_
below. Additionally, ``boost::parameter::python::function`` and
``boost::parameter::python::def`` requires a class with forwarding overloads.
We will take a closer look at how this is done in the tutorial section below.
.. The last two sentences are terribly vague. Which namespace is
.. ``function`` in? Isn't the return type always needed? What
.. else are we going to do other than pass these sequences to
.. function?

.. _parameterspec: `concept ParameterSpec`_
Tutorial
--------
In this section we will outline the steps needed to bind a simple
Boost.Parameter-enabled member function to Python. Knowledge of the
Boost.Parameter macros_ are required to understand this section.
.. _macros: index.html
The class and member function we are interested in binding looks
like this:
.. parsed-literal::
#include <boost/parameter/keyword.hpp>
#include <boost/parameter/preprocessor.hpp>
#include <boost/parameter/python.hpp>
#include <boost/python.hpp>
// First the keywords
BOOST_PARAMETER_KEYWORD(tag, title)
BOOST_PARAMETER_KEYWORD(tag, width)
BOOST_PARAMETER_KEYWORD(tag, height)
class window
{
public:
BOOST_PARAMETER_MEMBER_FUNCTION(
(void), open, tag,
(required (title, (std::string)))
(optional (width, (unsigned), 400)
(height, (unsigned), 400))
)
{
*… function implementation …*
}
};
.. @example.prepend('#include <cassert>')
.. @example.replace_emphasis('''
assert(title == "foo");
assert(height == 20);
assert(width == 400);
''')
It defines a set of overloaded member functions called ``open`` with one
required parameter and two optional ones. To bind this member function to
Python we use the binding utility ``boost::parameter::python::function``.
``boost::parameter::python::function`` is a |def_visitor|_ that we'll instantiate
and pass to ``boost::python::class_::def()``.
To use ``boost::parameter::python::function`` we first need to define
a class with forwarding overloads. This is needed because ``window::open()``
is a function template, so we can't refer to it in any other way.
::
struct open_fwd
{
template <class A0, class A1, class A2>
void operator()(
boost::type<void>, window& self
, A0 const& a0, A1 const& a1, A2 const& a2
)
{
self.open(a0, a1, a2);
}
};
The first parameter, ``boost::type<void>``, tells the forwarding overload
what the return type should be. In this case we know that it's always void
but in some cases, when we are exporting several specializations of a
Boost.Parameter-enabled template, we need to use that parameter to
deduce the return type.
``window::open()`` takes a total of 3 parameters, so the forwarding function
needs to take three parameters as well.
.. Note::
We only need one overload in the forwarding class, despite the
fact that there are two optional parameters. There are special
circumstances when several overload are needed; see
`special keywords`_.
Next we'll define the module and export the class:
::
BOOST_PYTHON_MODULE(my_module)
{
using namespace boost::python;
namespace py = boost::parameter::python;
namespace mpl = boost::mpl;
class_<window>("window")
.def(
"open", py::function<
open_fwd
, mpl::vector<
void
, tag::title(std::string)
, tag::width*(unsigned)
, tag::height*(unsigned)
>
>()
);
}
.. @jam_prefix.append('import python ;')
.. @jam_prefix.append('stage . : my_module /boost/python//boost_python ;')
.. @my_module = build(
output = 'my_module'
, target_rule = 'python-extension'
, input = '/boost/python//boost_python'
, howmany = 'all'
)
.. @del jam_prefix[:]
``py::function`` is passed two parameters. The first one is the class with
forwarding overloads that we defined earlier. The second one is an `MPL
Sequence`_ with the keyword tag types and argument types for the function
specified as function types. The pointer syntax used in ``tag::width*`` and
``tag::height*`` means that the parameter is optional. The first element of
the `MPL Sequence`_ is the return type of the function, in this case ``void``,
which is passed as the first argument to ``operator()`` in the forwarding
class.
.. The
pointer syntax means that the parameter is optional, so in this case
``width`` and ``height`` are optional parameters. The third parameter
is an `MPL Sequence`_ with the desired function signature. The return type comes first, and
then the parameter types:
.. parsed-literal::
mpl::vector<void, std::string, unsigned, unsigned>
*return type* *title* *width* *height*
.. @ignore()
That's it! This class can now be used in Python with the expected syntax::
>>> w = my_module.window()
>>> w.open(title = "foo", height = 20)
.. @example.prepend('import my_module')
.. @run_python(module_path = my_module)
.. Sorry to say this at such a late date, but this syntax really
.. strikes me as cumbersome. Couldn't we do something like:
class_<window>("window")
.def(
"open",
(void (*)(
tag::title(std::string),
tag::width*(unsigned),
tag::height*(unsigned))
)0
);
or at least:
class_<window>("window")
.def(
"open",
mpl::vector<
void,
tag::title(std::string),
tag::width*(unsigned),
tag::height*(unsigned)
>()
);
assuming, that is, that we will have to repeat the tags (yes,
users of broken compilers will have to give us function pointer
types instead).
------------------------------------------------------------------------------
concept |ParameterSpec|
-----------------------
A |ParameterSpec| is a function type ``K(T)`` that describes both the keyword tag,
``K``, and the argument type, ``T``, for a parameter.
``K`` is either:
* A *required* keyword of the form ``Tag``
* **or**, an *optional* keyword of the form ``Tag*``
* **or**, a *special* keyword of the form ``Tag**``
where ``Tag`` is a keyword tag type, as used in a specialization
of |keyword|__.
.. |keyword| replace:: ``boost::parameter::keyword``
__ ../../../parameter/doc/html/reference.html#keyword
The **arity range** for an `MPL Sequence`_ of |ParameterSpec|'s is
defined as the closed range:
.. parsed-literal::
[ mpl::size<S> - number of *special* keyword tags in ``S``, mpl::size<S> ]
For example, the **arity range** of ``mpl::vector2<x(int),y(int)>`` is ``[2,2]``,
the **arity range** of ``mpl::vector2<x(int),y*(int)>`` is ``[2,2]`` and the
**arity range** of ``mpl::vector2<x(int),y**(int)>`` is ``[1,2]``.
*special* keywords
---------------------------------
Sometimes it is desirable to have a default value for a parameter that differ
in type from the parameter. This technique is useful for doing simple tag-dispatching
based on the presence of a parameter. For example:
.. An example_ of this is given in the Boost.Parameter
docs. The example uses a different technique, but could also have been written like this:
.. parsed-literal::
namespace core
{
template <class ArgumentPack>
void dfs_dispatch(ArgumentPack const& args, mpl::false\_)
{
*…compute and use default color map…*
}
template <class ArgumentPack, class ColorMap>
void dfs_dispatch(ArgumentPack const& args, ColorMap colormap)
{
*…use colormap…*
}
}
template <class ArgumentPack>
void depth_first_search(ArgumentPack const& args)
{
core::dfs_dispatch(args, args[color | mpl::false_()]);
}
.. @example.prepend('''
#include <boost/parameter/keyword.hpp>
#include <boost/parameter/parameters.hpp>
#include <boost/mpl/bool.hpp>
#include <cassert>
BOOST_PARAMETER_KEYWORD(tag, color);
typedef boost::parameter::parameters<tag::color> params;
namespace mpl = boost::mpl;
''')
.. @example.replace_emphasis('''
assert(args[color | 1] == 1);
''')
.. @example.replace_emphasis('''
assert(args[color | 1] == 0);
''')
.. @example.append('''
int main()
{
depth_first_search(params()());
depth_first_search(params()(color = 0));
}''')
.. @build()
.. .. _example: index.html#dispatching-based-on-the-presence-of-a-default
In the above example the type of the default for ``color`` is ``mpl::false_``, a
type that is distinct from any color map that the user might supply.
When binding the case outlined above, the default type for ``color`` will not
be convertible to the parameter type. Therefore we need to tag the ``color``
keyword as a *special* keyword. This is done by specifying the tag as
``tag::color**`` when binding the function (see `concept ParameterSpec`_ for
more details on the tagging). By doing this we tell the binding functions that
it needs to generate two overloads, one with the ``color`` parameter present
and one without. Had there been two *special* keywords, four overloads would
need to be generated. The number of generated overloads is equal to 2\
:sup:`N`, where ``N`` is the number of *special* keywords.
