<h3>Unix Installation and Demo</h3>
|
||
|
|
<p>Note: distutils is not available for Python 1.5.2</p>
|
||
|
|
|
||
|
|
<ol>
|
||
|
|
<li>Fetch <a href="http://prdownloads.sourceforge.net/cxx/pycxx_5_3_1.tar.gz">
|
||
|
|
http://prdownloads.sourceforge.net/cxx/PyCXX-V5.3.0.tar.gz</a>
|
||
|
|
<li>Login as root. root access is typically needed on Unix systems to install the PyCXX files into the Python directories.
|
||
|
|
<li>Expand the archive into a directory of your choosing ~\ for example.
|
||
|
|
<li>Install the PyCXX files:
|
||
|

|
||
|
|
<p>Added support for custom Exceptions</p>
|
||
|
|
<p></p>
|
||
|
|
|
||
|
|
<h3>Version 5.1 (2-Aug-2001)</h3>
|
||
|
|
<p>I'm using the name PyCXX for this package, CXX is far to close to a compilers name.</p>
|
||
|
|
|
||
|
|
<p>PyCXX supports Python version 2.2, 2.1.1, 2.1, 2.0, 2.0.1 and 1.5.2 on Windows and Unix.</p>
|
||
|
|
|
||
|
|
<p>New in this release:</p>
|
||
|
|
<ul>
|
||
|
|
<li>Support for the Windows Linker /DELAYLOAD feature. Enable this feature by
|
||
|
|
defining PY_WIN32_DELAYLOAD_PYTHON_DLL when compiling IndirectPythonInterface.cxx
|
||
|
|
<li>Remove "CXX/Array.hxx" and associated code - its does not belong in PyCXX
|
||
|
|
<li>Work on the docs. Mostly to clean up the HTML to allow more extensive work.
|
||
|
|
<li>Reformated the sources to a consistent style. The mix of styles and tabs sizes
|
||
|
|
was making working on the sources error prone.
|
||
|
|
<li>Added workaround to setup.py to allow GCC to compile c++ code.
|
||
|
|
<li>Added Microsoft Visual C++ 6.0 project files for 1.5, 2.0 and 2.1 builds
|
||
|
|
<li>Added Unix make files for Linux (tested on RedHat 7.1) and FreeBSD (tested on 4.3)
|
||
|
|
<li>Merged changes from Tom Malcolmson

|
||
|
|
C++ header files.

<h3>Version 5 (May 18, 2000)</h3>
|
||
|
|
<p>This version adds Distutils support for installation and some code cleanup.</p>
|
||
|
|
|
||
|
|
<h3>Version 4 (October 11, 1999)</h3>
|
||
|
|
|
||
|
|
<p>This version contains a massive revision to the part of CXX that supports creating
|
||
|
|
extension objects and extension modules. Barry Scott contributed these changes.</p>
|
||
|
|
|
||
|
|
<p>CXX has always consisted of two parts: the basic CXX_Objects.h and the more
|
||
|
|
experimental CXX_Extensions.h. We will describe the changes to CXX_Objects first, and then
|
||
|
|
the changes to CXX_Extensions.h.</p>
|
||
|
|
|
||
|
|
<h3>Changes to CXX_Objects</h3>
|
||
|
|
|
||
|
|
<h4>1. Owned option eliminates need for FromAPI in most cases</h4>
|
||
|
|
|
||
|
|
<p>Object's constructor from PyObject* and method set have a new (backward compatible)
|
||
|
|
signature:</p>
|
||
|
|
|
||
|
|
<pre>
|
||
|
|
Object (PyObject* pyob, bool owned = false);
|
||
|
|
void set(PyObject* pyob, bool owned = false);
|
||
|
|
</pre>
|
||
|
|
|
||
|
|
<p>Users may call these with owned = true if they own the reference pyob already and want
|
||
|
|
the Object instance to take over ownership.</p>
|
||
|
|
|
||
|
|
<p>A new inline function Object asObject(PyObject* pyob) returns Object(pyob, true); thus,
|
||
|
|
one way to construct an object from a pointer returned by the Python API is to call
|
||
|
|
asObject on it. </p>
|
||
|
|
|
||
|
|
<p>Previously a class FromAPI was provided to solve the problem of taking over an owned
|
||
|
|
reference. FromAPI will be eliminated in the next release. It is no longer used by CXX
|
||
|
|
itself or its demos. The new mechanism is much cleaner and more efficient.</p>
|
||
|
|
|
||
|
|
<p>Other classes in CXX have been given the same "owned" option on their
|
||
|
|
constructors: Int, Float, Long, Complex, SeqBase<T>, Tuple, List, Dict, Module,
|
||
|
|
Callable.</p>
|
||
|
|
|
||
|
|
<h4>2. Namespace support in compiler assumed</h4>
|
||
|
|
|
||
|
|
<p>Since EGCS / GCC now supports namespaces and the standard library, the need for
|
||
|
|
CXX_config.h is almost gone. We have eliminated all the macros except for one obscure one
|
||
|
|
dealing with iterator traits in the standard library.</p>
|
||
|
|
|
||
|
|
<h3>Changes to CXX_Extensions</h3>
|
||
|
|
|
||
|
|
<p>The changes to CXX_Extensions.h are not backward compatible. However, they simplify
|
||
|
|
coding so much that we think it is worth the disruption.</p>
|
||
|
|
|
||
|
|
<h4>1. Creating an extension module</h4>
|
||
|
|
|
||
|
|
<p>To create an extension module, you inherit from class ExtensionModule templated on
|
||
|
|
yourself: In the constructor, you make calls to register methods of this class with Python
|
||
|
|
as extension module methods. In this example, two methods are added (this is a simplified
|
||
|
|
form of the example in Demo/example.cxx):</p>
|
||
|
|
|
||
|
|
<pre>class example_module : public ExtensionModule<example_module>
|
||
|
|
{
|
||
|
|
public:
|
||
|
|
example_module()
|
||
|
|
: ExtensionModule<example_module>( "example" )
|
||
|
|
{
|
||
|
|
add_varargs_method("sum", &example_module::ex_sum, "sum(arglist) = sum of arguments");
|
||
|
|
add_varargs_method("test", &example_module::ex_test, "test(arglist) runs a test suite");
|
||
|
|
|
||
|
|
initialize( "documentation for the example module" );
|
||
|
|
}
|
||
|
|
|
||
|
|
virtual ~example_module() {}
|
||
|
|
|
||
|
|
private:
|
||
|
|
Object ex_sum (const Tuple &a) { ... }
|
||
|
|
Object ex_test( const Tuple &a) { ... }
|
||
|
|
};
|
||
|
|
</pre>
|
||
|
|
|
||
|
|
<p>To initialize the extension, you just instantiate one static instance (static so it
|
||
|
|
doesn't destroy itself!):</p>
|
||
|
|
|
||
|
|
<pre>
|
||
|
|
void initexample()
|
||
|
|
{
|
||
|
|
static example_module* example = new example_module;
|
||
|
|
}
|
||
|
|
</pre>
|
||
|
|
|
||
|
|
<p>The methods can be written to take Tuples as arguments and return Objects. If
|
||
|
|
exceptions occur they are trapped for you and a Python exception is generated. So, for
|
||
|
|
example, the implementation of ex_sum might be:</p>
|
||
|
|
|
||
|
|
<pre>
|
||
|
|
Object ex_sum (const Tuple &a)
|
||
|
|
{
|
||
|
|
Float f(0.0);
|
||
|
|
for( int i = 0; i < a.length(); i++ )
|
||
|
|
{
|
||
|
|
Float g(a[i]);
|
||
|
|
f = f + g;
|
||
|
|
}
|
||
|
|
return f;
|
||
|
|
}
|
||
|
|
</pre>
|
||
|
|
|
||
|
|
<p>class ExtensionModule contains methods to return itself as a Module object, or to
|
||
|
|
return its dictionary.</p>
|
||
|
|
|
||
|
|
<h4>Creating extension objects</h4>
|
||
|
|
|
||
|
|
<p>Creating extension objects is of course harder since you must specify how the object
|
||
|
|
behaves and give it methods. This is shown in some detail in the example range.h and range.cxx,
|
||
|
|
with the test routine rangetest.cxx, in directory Demo.</p>
|
||
|
|
|
||
|
|
<p>Here is a brief overview. You create a class that inherits from PythonExtension
|
||
|
|
templated upon itself. You override various methods from PythonExtension to implement
|
||
|
|
behaviors, such as getattr, sequence_item, etc. You can also add methods to the object
|
||
|
|
that are usable from Python using a similar scheme as for module methods above. </p>
|
||
|
|
|
||
|
|
<p>One of the consequences of inheriting from PythonExtension is that you are inheriting
|
||
|

from PyObject itself. So your class is-a PyObject and instances of it can be passed to the
|
||
|
|
Python C API. Note: this example uses the namespace feature of CXX. The Py:: 's are not
|
||
|
|
required if you use the namespace instead.</p>

To initialize the type you provide a static method that you can call from some module's

|
initializer. This method sets the name, doc string, and indicates which behaviors it
|

|
|
supports. It then adds the methods.</p>

<h3>Version 3 (June 18, 1999)</h3>
|
||
|
|
|
||
|
|
<p>1. CXX compiles with EGCS snapshot 19990616. EGCS requires a standard library class
|
||
|
|
random_access_iterator that is not yet available in some other compilers (such as Windows
|
||
|
|
VC6). Therefore a new switch:</p>
|
||
|
|
|
||
|
|
<p>STANDARD_LIBRARY_HAS_ITERATOR_TRAITS</p>
|
||
|
|
|
||
|
|
<p>has been added to CXX_Config.h that you may need to toggle if you get an error on the
|
||
|
|
two lines that mention random_access_iterator. The current definition is correct for VC6
|
||
|
|
and EGCS-19990616. </p>
|
||
|
|
|
||
|
|
<p>2. A new constructor was added to Module to allow construction from a string containing
|
||
|
|
the module name. A test was added for this to the demo.</p>
|
||
|
|
|
||
|
|
<h3>Version 2 (Dec. 28, 1998)</h3>
|
||
|
|
|
||
|
|
<p>Fixed definition of extension type to match 1.5.2. This version will presumably not
|
||
|
|
compile with older versions of Python. This can be fixed by using the previous version's
|
||
|
|
definition. I did not take the time to find out what these new "flags" are for
|
||
|
|
nor put in any methods to deal with them.</p>
|
||
|
|
|
||
|
|
<h3>Version 1</h3>
|
||
|
|
|
||
|
|
<p>This is an experimental set of files for supporting the creation of Python extensions
|
||
|
|
in C++. </p>
|
||
|
|
|
||
|
|
<p>Documentation is in progress at <a href="http://xfiles.llnl.gov">http://xfiles.llnl.gov</a>.
|
||
|
|
</p>
|
||
|
|
|
||
|
|
<p>To use CXX you use the header files in Include, such as CXX_Objects.h or
|
||
|
|
CXX_Extensions.h. You must include the sources in Src in your sources to supply parts of
|
||
|
|
the CXX classes required.</p>
|
||
|
|
|
||
|
|
<p>A demo is included. The Setup file in this directory compiles this demo named
|
||
|
|
"example". To try the demo, which is also a test routine, you import example and
|
||
|
|
then execute:</p>
|
||
|
|
|
||
|
|
<pre>
|
||
|
|
example.test()
|
||
|
|
</pre>
|
||
|
|
|
||
|
|
<p>You can also play with the extension object whose constructor is named "range":</p>
|
||
|
|
|
||
|
|
<pre>
|
||
|
|
s = range(1, 100, 2)
|
||
|
|
print s[2] # should print 5
|
||
|
|
</pre>
|
||
|
|
|
||
|
|
<p>Compilation with Microsoft Visual C++ 5.0 will succeed but only if you have Service
|
||
|
|
Pack 3 installed. Compilation has been known to succeed on a Unix system using KCC by
|
||
|
|
using:</p>
|
||
|
|
|
||
|
|
<pre>
|
||
|
|
setenv CCC "KCC -x"
|
||
|
|
</pre>
|
||
|
|
|
||
|
|
<p>before running makethis.py.</p>
|
||
|
|
|
||
|
|
<p>There is also a python.cxx file for making a stand-alone Python containing this
|
||
|
|
example, as well as a similar file arraytest.cxx for testing Array.</p>
