Applied 2 patches by Prabhu Ramachandran: a fix in the new --multiple method,
|
||||
and two new functions "hold_with_shared_ptr" and its counterpart for auto_ptr.
|
||||
Thanks a lot Prabhu!
|
||||
|
||||
Fixed a bug where the macro BOOST_PYTHON_OPAQUE_SPECIALIZED_TYPE_ID was being
|
||||
called multiple times for the same type.
|
||||
Thanks to Gottfried Ganßauge for reporting this!
|
||||
|
||||
Fixed bug where using AllFromHeader didn't use bases<> when exporting
|
||||
hierarchies.
|
||||
|
||||
Fixed the staticmethod bug.
|
||||
|
||||
5 July 2003
|
||||
Changed how --multiple works: now it generates one cpp file for each pyste
|
||||
file, makeing easier to integrate Pyste with build systems.
|
||||
|
||||
4 July 2003
|
||||
Applied patch that solved a bug in ClassExporter and added a distutils install
|
||||
script (install/setup.py), both contributed by Prabhu Ramachandran.
|
||||
Thanks Prabhu!
|
||||
|

2 July 2003

Jim Wilson found a bug where types like "char**" were being interpreted as
|
||||
"char*". Thanks Jim!
|
||||
|
||||
16 June 2003
|
||||
Thanks to discussions with David Abrahams and Roman Sulzhyk, some behaviours
|
||||
have changed:
|
||||
|
||||
- If you export a derived class without exporting its base classes, the derived
|
||||
class will explicitly export the bases's methods and attributes. Before, if
|
||||
you were interested in the bases's methods, you had to export the base
|
||||
classes too.
|
||||
|
||||
- Added a new function, no_override. When a member function is specified as
|
||||
"no_override", no virtual wrappers are generated for it, improving
|
||||
performance and letting the code more clean.
|
||||
|
||||
- There was a bug in which the policy of virtual member functions was being
|
||||
ignored (patch by Roman Sulzhyk).
|
||||
|
||||
Thanks again to Roman Sulzhyk for the patches and discussion in the c++-sig.
|
||||
|
||||
4 June 2003
|
||||
Major improvements in memory usage.
|
||||
|
||||
3 June 2003
|
||||
Appliced a patch from Giulio Eulisse that allows unnamed enumerations to be
|
||||
exported with an AllFromHeader construct. Thanks a lot Giulio!
|
||||
|
||||
2 June 2003
|
||||
Added a new construct, add_method. See documentation.
|
||||
|
||||
23 May 2003
|
||||
Support for global variables added.
|
||||
Various bug fixes.
|
||||
|
||||
08 May 2003
|
||||
Fixed bug where in a certain cases the GCCXMLParser would end up with multiple
|
||||
declarations of the same class
|
||||
|
||||
22 Apr 2003
|
||||
- Now shows a warning when the user tries to export a forward-declared class.
|
||||
Forward-declared classes are ignored by the AllFromHeader construct.
|
||||
- Fixed a bug where classes, functions and enums where being exported, even if
|
||||
excluded from a AllFromHeader construct.
|
||||
|
||||
16 Apr 2003
|
||||
Added a more generic (but ugly) code to declare the smart pointer converters.
|
||||
|
||||
07 Apr 2003
|
||||
- Removed the warnings about forward declarations: it was not accurate enough.
|
||||
Another strategy must be thought of.
|
||||
- Fixed bug in the --multiple mode, where the order of the class instantiations
|
||||
could end up wrong.
|
||||
- Lots of fixes in the documentation, pointed out by Dirk Gerrits. Thanks Dirk!
|
||||
- Fixed support for the return_opaque_pointer policy (the support macro was not
|
||||
being declared).
|
||||
|
||||
|
||||
06 Apr 2003
|
||||
Support for the improved static data members support of Boost.Python.
|
||||
|
||||
05 Apr 2003
|
||||
New option for generating the bindings: --multiple.
|
||||
|
||||
02 Apr 2003
|
||||
Forward declarations are now detected and a warning is generated.
|
||||
|
||||
24 Mar 2003
|
||||
Default policy for functions/methods that return const T& is now
|
||||
return_value_policy<copy_const_reference>().
|
||||
|
||||
22 Mar 2003
|
||||
Exporting virtual methods of the base classes in the derived classes too.
|
||||
|
||||
21 Mar 2003
|
||||
Added manual support for boost::shared_ptr and std::auto_ptr (see doc).
|
||||
|
||||
19 Mar 2003
|
||||
Added support for int, double, float and long operators acting as expected in
|
||||
python.
|
||||
|
||||
14 Mar 2003
|
||||
Fixed bug: Wrappers for protected and virtual methods were not being generated.

Pyste - Python Semi-Automatic Exporter
|
||||
======================================
|
||||
|
||||
Pyste is a Boost.Python code generator. The user specifies the classes and
|
||||
functions to be exported using a simple interface file, which following the
|
||||
Boost.Python's philosophy, is simple Python code. Pyste then uses GCCXML to
|
||||
parse all the headers and extract the necessary information to automatically
|
||||
generate C++ code.
|
||||
|
||||
The documentation can be found in the file index.html accompaning this README.
|
||||
|
||||
Enjoy!

If possible, run pyste with --debug, and send the resulting xmls too (pyste

Suppose that you want to add a function to a class, turning it into a member
|
||||
function:</p>
|
||||
<code><pre>
|
||||
<span class=keyword>struct </span><span class=identifier>World
|
||||
</span><span class=special>{
|
||||
</span><span class=keyword>void </span><span class=identifier>set</span><span class=special>(</span><span class=identifier>std</span><span class=special>::</span><span class=identifier>string </span><span class=identifier>msg</span><span class=special>) { </span><span class=keyword>this</span><span class=special>-></span><span class=identifier>msg </span><span class=special>= </span><span class=identifier>msg</span><span class=special>; }
|
||||
</span><span class=identifier>std</span><span class=special>::</span><span class=identifier>string </span><span class=identifier>msg</span><span class=special>;
|
||||
};
|
||||
|
||||
</span><span class=identifier>std</span><span class=special>::</span><span class=identifier>string </span><span class=identifier>greet</span><span class=special>(</span><span class=identifier>World</span><span class=special>& </span><span class=identifier>w</span><span class=special>)
|
||||
{
|
||||
</span><span class=keyword>return </span><span class=identifier>w</span><span class=special>.</span><span class=identifier>msg</span><span class=special>;
|
||||
}
|
||||
</span></pre></code>
|
||||
<p>
|
||||
Here, we want to make <tt>greet</tt> work as a member function of the class <tt>World</tt>. We do
|
||||
that using the <tt>add_method</tt> construct:</p>
|
||||
<code><pre>
|
||||
<span class=identifier>W </span><span class=special>= </span><span class=identifier>Class</span><span class=special>(</span><span class=string>"World"</span><span class=special>, </span><span class=string>"hello.h"</span><span class=special>)
|
||||
</span><span class=identifier>add_method</span><span class=special>(</span><span class=identifier>W</span><span class=special>, </span><span class=string>"greet"</span><span class=special>)
|
||||
</span></pre></code>
|
||||
<p>
|
||||
Notice also that then you can rename it, set its policy, just like a regular
|
||||
member function:</p>
|
||||
<code><pre>
|
||||
<span class=identifier>rename</span><span class=special>(</span><span class=identifier>W</span><span class=special>.</span><span class=identifier>greet</span><span class=special>, </span><span class=literal>'Greet'</span><span class=special>)
|
||||
</span></pre></code>
|
||||
<p>
|
||||
Now from Python:</p>
|
||||
<code><pre>
|
||||
<span class=special>>>> </span><span class=identifier>import </span><span class=identifier>hello
|
||||
</span><span class=special>>>> </span><span class=identifier>w </span><span class=special>= </span><span class=identifier>hello</span><span class=special>.</span><span class=identifier>World</span><span class=special>()
|
||||
>>> </span><span class=identifier>w</span><span class=special>.</span><span class=identifier>set</span><span class=special>(</span><span class=literal>'Ni'</span><span class=special>)
|
||||
>>> </span><span class=identifier>w</span><span class=special>.</span><span class=identifier>greet</span><span class=special>()
|
||||
</span><span class=literal>'Ni'
|
||||
</span><span class=special>>>> </span><span class=identifier>print </span><span class=literal>'Oh no! The knights who say Ni!'
|
||||
</span><span class=identifier>Oh </span><span class=identifier>no</span><span class=special>! </span><span class=identifier>The </span><span class=identifier>knights </span><span class=identifier>who </span><span class=identifier>say </span><span class=identifier>Ni</span><span class=special>!

|

<p>
|

You can just use the <tt>AllFromHeader</tt> construct:</p>
|
||||
<code><pre>
|
||||
<span class=identifier>hello </span><span class=special>= </span><span class=identifier>AllFromHeader</span><span class=special>(</span><span class=string>"hello.h"</span><span class=special>)
|
||||
</span></pre></code>
|
||||
<p>
|
||||
this will export all the declarations found in <tt>hello.h</tt>, which is equivalent
|
||||
to write:</p>
|
||||
<code><pre>
|
||||
<span class=identifier>Class</span><span class=special>(</span><span class=string>"World"</span><span class=special>, </span><span class=string>"hello.h"</span><span class=special>)
|
||||
</span><span class=identifier>Enum</span><span class=special>(</span><span class=string>"choice"</span><span class=special>, </span><span class=string>"hello.h"</span><span class=special>)
|
||||
</span><span class=identifier>Function</span><span class=special>(</span><span class=string>"show"</span><span class=special>, </span><span class=string>"hello.h"</span><span class=special>)
|
||||
</span></pre></code>
|
||||
<p>
|
||||
Note that you can still use the functions <tt>rename</tt>, <tt>set_policy</tt>, <tt>exclude</tt>, etc. Just access
|
||||
the members of the header object like this:</p>
|
||||
<code><pre>
|
||||
<span class=identifier>rename</span><span class=special>(</span><span class=identifier>hello</span><span class=special>.</span><span class=identifier>World</span><span class=special>.</span><span class=identifier>greet</span><span class=special>, </span><span class=string>"Greet"</span><span class=special>)
|
||||
</span><span class=identifier>exclude</span><span class=special>(</span><span class=identifier>hello</span><span class=special>.</span><span class=identifier>World</span><span class=special>.</span><span class=identifier>set</span><span class=special>, </span><span class=string>"Set"</span><span class=special>)

Even thought Pyste can identify various elements in the C++ code, like virtual
|
||||
member functions, attributes, and so on, one thing that it can't do is to
|
||||
guess the semantics of functions that return pointers or references. In this
|
||||
case, the user must manually specify the policy. Policies are explained in the
|
||||
<a href="../../doc/tutorial/doc/call_policies.html">
|
||||
tutorial</a>.</p>
|
||||
<p>
|
||||
The policies in Pyste are named exactly as in <a href="../../index.html">
|
||||
Boost.Python</a>, only the syntax is
|
||||
slightly different. For instance, this policy:</p>
|
||||
<code><pre>
|
||||
<span class=identifier>return_internal_reference</span><span class=special><</span><span class=number>1</span><span class=special>, </span><span class=identifier>with_custodian_and_ward</span><span class=special><</span><span class=number>1</span><span class=special>, </span><span class=number>2</span><span class=special>> >()
|
||||
</span></pre></code>
|
||||
<p>
|
||||
becomes in Pyste: </p>
|
||||
<code><pre>
|
||||
<span class=identifier>return_internal_reference</span><span class=special>(</span><span class=number>1</span><span class=special>, </span><span class=identifier>with_custodian_and_ward</span><span class=special>(</span><span class=number>1</span><span class=special>, </span><span class=number>2</span><span class=special>))
|
||||
</span></pre></code>
|

<p>
|

The user can specify policies for functions and virtual member functions with
|
||||
the <tt>set_policy</tt> function:</p>
|

<code><pre>
|

<span class=identifier>set_policy</span><span class=special>(</span><span class=identifier>f</span><span class=special>, </span><span class=identifier>return_internal_reference</span><span class=special>())

[h2 What is Pyste?]
|
||||
|
||||
Pyste is a Boost.Python code generator. The user specifies the classes and
|
||||
functions to be exported using a simple ['interface file], which following the
|
||||
Boost.Python's philosophy, is simple Python code. Pyste then uses GCCXML to
|
||||
parse all the headers and extract the necessary information to automatically
|
||||
generate C++ code.
|
||||
|
||||
[h2 Example]
|
||||
|
||||
Let's borrow the class [^World] from the [@../../doc/tutorial/doc/exposing_classes.html tutorial]:
|
||||
|
||||
struct World
|
||||
{
|
||||
void set(std::string msg) { this->msg = msg; }
|
||||
std::string greet() { return msg; }
|
||||
std::string msg;
|
||||
};
|
||||
|
||||
Here's the interface file for it, named [^world.pyste]:
|
||||
|
||||
Class("World", "world.h")
|
||||
|
||||
and that's it!
|
||||
|
||||
The next step is invoke Pyste in the command-line:
|
||||
|
||||
[pre python pyste.py --module=hello world.pyste]
|
||||
|
||||
this will create a file "[^hello.cpp]" in the directory where the command was
|
||||
run.
|
||||
|
||||
Pyste supports the following features:
|
||||
|
||||
* Functions
|
||||
* Classes
|
||||
* Class Templates
|
||||
* Virtual Methods
|
||||
* Overloading
|
||||
* Attributes
|
||||
* Enums (both "free" enums and class enums)
|
||||
* Nested Classes
|
||||
* Support for [^boost::shared_ptr] and [^std::auto_ptr]
|
||||
* Global Variables
|
||||
|
||||
[page Running Pyste]
|
||||
|
||||
To run Pyste, you will need:
|
||||
|
||||
* Python 2.2, available at [@http://www.python.org python's website].
|
||||
* The great [@http://effbot.org elementtree] library, from Fredrik Lundh.
|
||||
* The excellent GCCXML, from Brad King.
|
||||
|
||||
Installation for the tools is available in their respective webpages.
|
||||
|
||||
[blurb
|
||||
[$theme/note.gif] GCCXML must be accessible in the PATH environment variable, so
|
||||
that Pyste can call it. How to do this varies from platform to platform.
|
||||
]
|
||||
|
||||
[h2 Ok, now what?]
|
||||
|
||||
Well, now let's fire it up:
|
||||
|
||||
[pre
|
||||
'''
|
||||
>python pyste.py
|
||||
|
||||
Pyste version 0.6.5
|
||||
|
||||
Usage:
|
||||
pyste [options] --module=<name> interface-files
|
||||
|
||||
where options are:
|
||||
-I <path> add an include path
|
||||
-D <symbol> define symbol
|
||||
--multiple create various cpps (one for each pyste file), instead
|
||||
of only one (useful during development)
|
||||
--out specify output filename (default: <module>.cpp)
|
||||
in --multiple mode, this will be a directory
|
||||
--no-using do not declare "using namespace boost";
|
||||
use explicit declarations instead
|
||||
--pyste-ns=<name> set the namespace where new types will be declared;
|
||||
default is the empty namespace
|
||||
--debug writes the xml for each file parsed in the current
|
||||
directory
|
||||
-h, --help print this help and exit
|
||||
-v, --version print version information

The [^-I] and [^-D] are preprocessor flags, which are needed by GCCXML to parse
|
||||
the header files correctly and by Pyste to find the header files declared in the
|
||||
interface files.
|
||||
|
||||
[^--multiple] tells Pyste to generate multiple cpps for this module (one for
|
||||
each header parsed) in the directory named by [^--out], instead of the usual
|
||||
single cpp file. This mode is useful during development of a binding, because
|
||||
you are constantly changing source files, re-generating the bindings and
|
||||
recompiling. This saves a lot of time in compiling.
|
||||
|
||||
[^--out] names the output file (default: [^<module>.cpp]), or in multiple mode,
|
||||
names a output directory for the files (default: [^<module>]).
|
||||
|
||||
[^--no-using] tells Pyste to don't declare "[^using namespace boost;]" in the
|
||||
generated cpp, using the namespace boost::python explicitly in all declarations.
|
||||
Use only if you're having a name conflict in one of the files.
|
||||
|
||||
Use [^--pyste-ns] to change the namespace where new types are declared (for
|
||||
instance, the virtual wrappers). Use only if you are having any problems. By
|
||||
default, Pyste uses the empty namespace.
|
||||
|
||||
[^--debug] will write in the current directory a xml file as outputted by GCCXML
|
||||
for each header parsed. Useful for bug reports.
|
||||
|
||||
[^-h, --help, -v, --version] are self-explaining, I believe. ;)
|
||||
|
||||
So, the usage is simple enough:
|
||||
|
||||
[pre >python pyste.py --module=mymodule file.pyste file2.pyste ...]
|
||||
|
||||
will generate a file [^mymodule.cpp] in the same dir where the command was
|
||||
executed. Now you can compile the file using the same instructions of the
|
||||
[@../../doc/tutorial/doc/building_hello_world.html tutorial]. Or, if you prefer:
|
||||
|
||||
[pre >python pyste.py --module=mymodule --multiple file.pyste file2.pyste ...]
|
||||
|
||||
will create a directory named "mymodule" in the current directory, and will
|
||||
generate a bunch of cpp files, one for each header exported. You can then
|
||||
compile them all into a single shared library (or dll).
|
||||
|
||||
[h2 Wait... how do I set those I and D flags?]
|
||||
|
||||
Don't worry: normally GCCXML is already configured correctly for your plataform,
|
||||
so the search path to the standard libraries and the standard defines should
|
||||
already be set. You only have to set the paths to other libraries that your code
|
||||
needs, like Boost, for example.
|
||||
|
||||
Plus, Pyste automatically uses the contents of the environment variable
|
||||
[^INCLUDE] if it exists. Visual C++ users should run the [^Vcvars32.bat] file,
|
||||
which for Visual C++ 6 is normally located at:
|
||||
|
||||
C:\Program Files\Microsoft Visual Studio\VC98\bin\Vcvars32.bat
|
||||
|
||||
with that, you should have little trouble setting up the flags.
|
||||
|
||||
[blurb [$theme/note.gif][*A note about Psyco][br][br]
|
||||
Although you don't have to install [@http://psyco.sourceforge.net/ Psyco] to use Pyste, if you do, Pyste will make use of it to speed up the wrapper generation. Speed ups of 30% can be achieved, so it's highly recommended.
|
||||

|
||||
|
||||
[page The Interface Files]
|
||||
|
||||
The interface files are the heart of Pyste. The user creates one or more
|
||||
interface files declaring the classes and functions he wants to export, and then
|
||||
invokes Pyste passing the interface files to it. Pyste then generates a single
|
||||
cpp file with Boost.Python code, with all the classes and functions exported.
|
||||
|
||||
Besides declaring the classes and functions, the user has a number of other
|
||||
options, like renaming e excluding classes and member functionis. Those are
|
||||
explained later on.
|
||||
|
||||
[h2 Basics]
|
||||
|
||||
Suppose we have a class and some functions that we want to expose to Python
|
||||
declared in the header [^hello.h]:
|
||||
|
||||
struct World
|
||||
{
|
||||
World(std::string msg): msg(msg) {}
|
||||
void set(std::string msg) { this->msg = msg; }
|
||||
std::string greet() { return msg; }
|
||||
std::string msg;
|
||||
};
|
||||
|
||||
enum choice { red, blue };
|
||||
|
||||
namespace test {
|
||||
|
||||
void show(choice c) { std::cout << "value: " << (int)c << std::endl; }
|
||||
|
||||
}
|
||||
|
||||
We create a file named [^hello.pyste] and create instances of the classes
|
||||
[^Function], [^Class] and [^Enum]:
|
||||
|
||||
Function("test::show", "hello.h")
|
||||
Class("World", "hello.h")
|
||||
Enum("choice", "hello.h")
|
||||
|
||||
That will expose the class, the free function and the enum found in [^hello.h].
|
||||
|
||||
[page:1 Renaming and Excluding]
|
||||
|
||||
You can easily rename functions, classes, member functions, attributes, etc. Just use the
|
||||
function [^rename], like this:
|
||||
|
||||
World = Class("World", "hello.h")
|
||||
rename(World, "IWorld")
|
||||
show = Function("choice", "hello.h")
|
||||
rename(show, "Show")
|
||||
|
||||
You can rename member functions and attributes using this syntax:
|
||||
|
||||
rename(World.greet, "Greet")
|
||||
rename(World.set, "Set")
|
||||
choice = Enum("choice", "hello.h")
|
||||
rename(choice.red, "Red")
|
||||
rename(choice.blue, "Blue")
|
||||
|
||||
You can exclude functions, classes, member functions, attributes, etc, in the same way,
|
||||
with the function [^exclude]:
|
||||
|
||||
exclude(World.greet)
|
||||
exclude(World.msg)
|
||||
|
||||
To access the operators of a class, access the member [^operator] like this
|
||||
(supposing that [^C] is a class being exported):
|
||||
|
||||
exclude(C.operator['+'])
|
||||
exclude(C.operator['*'])
|
||||
exclude(C.operator['<<'])
|
||||
|
||||
The string inside the brackets is the same as the name of the operator in C++.[br]
|
||||
|
||||
[h2 Virtual Member Functions]
|
||||
|
||||
Pyste automatically generates wrappers for virtual member functions, but you
|
||||
may want to disable this behaviour (for performance reasons, or to let the
|
||||
code more clean) if you do not plan to override the functions in Python. To do
|
||||
this, use the function [^final]:
|
||||
|
||||
C = Class('C', 'C.h')
|
||||
final(C.foo) # C::foo is a virtual member function
|
||||
|
||||
No virtual wrapper code will be generated for the virtual member function
|
||||
C::foo that way.
|
||||
|
||||
[page:1 Policies]
|
||||
|
||||
Even thought Pyste can identify various elements in the C++ code, like virtual
|
||||
member functions, attributes, and so on, one thing that it can't do is to
|
||||
guess the semantics of functions that return pointers or references. In this
|
||||
case, the user must manually specify the policy. Policies are explained in the
|
||||
[@../../doc/tutorial/doc/call_policies.html tutorial].
|
||||
|
||||
The policies in Pyste are named exactly as in Boost.Python, only the syntax is
|
||||
slightly different. For instance, this policy:
|
||||
|
||||
return_internal_reference<1, with_custodian_and_ward<1, 2> >()
|
||||
|
||||
becomes in Pyste:
|
||||
|
||||
return_internal_reference(1, with_custodian_and_ward(1, 2))
|
||||
|
||||
The user can specify policies for functions and virtual member functions with
|
||||
the [^set_policy] function:
|
||||
|
||||
set_policy(f, return_internal_reference())
|
||||
set_policy(C.foo, return_value_policy(manage_new_object))
|
||||
|
||||
[blurb
|
||||
[$theme/note.gif] [*What if a function or member function needs a policy and
|
||||
the user doesn't set one?][br][br] If a function needs a policy and one
|
||||
was not set, Pyste will issue a error. The user should then go in the
|
||||
interface file and set the policy for it, otherwise the generated cpp won't
|
||||
compile.
|
||||
]
|
||||
|
||||
[blurb
|
||||
[$theme/note.gif]
|
||||
Note that, for functions that return [^const T&], the policy
|
||||
[^return_value_policy<copy_const_reference>()] wil be used by default, because
|
||||
that's normally what you want. You can change it to something else if you need
|
||||
to, though.
|
||||
]
|
||||
|
||||
[page:1 Templates]
|
||||
|
||||
Template classes can easily be exported too, but you can't export the template
|
||||
itself... you have to export instantiations of it! So, if you want to export a
|
||||
[^std::vector], you will have to export vectors of int, doubles, etc.
|
||||
|
||||
Suppose we have this code:
|
||||
|
||||
template <class T>
|
||||
struct Point
|
||||
{
|
||||
T x;
|
||||
T y;
|
||||
};
|
||||
|
||||
And we want to export [^Point]s of int and double:
|
||||
|
||||
Point = Template("Point", "point.h")
|
||||
Point("int")
|
||||
Point("double")
|
||||
|
||||
Pyste will assign default names for each instantiation. In this example, those
|
||||
would be "[^Point_int]" and "[^Point_double]", but most of the time users will want to
|
||||
rename the instantiations:
|
||||
|
||||
Point("int", "IPoint") // renames the instantiation
|
||||
double_inst = Point("double") // another way to do the same
|
||||
rename(double_inst, "DPoint")
|
||||
|
||||
Note that you can rename, exclude, set policies, etc, in the [^Template] object
|
||||
like you would do with a [^Function] or a [^Class]. This changes affect all
|
||||
[*future] instantiations:
|
||||
|
||||
Point = Template("Point", "point.h")
|
||||
Point("float", "FPoint") // will have x and y as data members
|
||||
rename(Point.x, "X")
|
||||
rename(Point.y, "Y")
|
||||
Point("int", "IPoint") // will have X and Y as data members
|
||||
Point("double", "DPoint") // also will have X and Y as data member
|
||||
|
||||
If you want to change a option of a particular instantiation, you can do so:
|
||||
|
||||
Point = Template("Point", "point.h")
|
||||
Point("int", "IPoint")
|
||||
d_inst = Point("double", "DPoint")
|
||||
rename(d_inst.x, "X") // only DPoint is affect by this renames,
|
||||
rename(d_inst.y, "Y") // IPoint stays intact
|
||||
|
||||
[blurb [$theme/note.gif] [*What if my template accepts more than one type?]
|
||||
[br][br]
|
||||
When you want to instantiate a template with more than one type, you can pass
|
||||
either a string with the types separated by whitespace, or a list of strings
|
||||
'''("int double" or ["int", "double"]''' would both work).
|
||||
]
|
||||
|
||||
[page:1 Wrappers]
|
||||
|
||||
Suppose you have this function:
|
||||
|
||||
std::vector<std::string> names();
|
||||
|
||||
But you don't want to export [^std::vector<std::string>], you want this function
|
||||
to return a python list of strings. Boost.Python has excellent support for
|
||||
that:
|
||||
|
||||
list names_wrapper()
|
||||
{
|
||||
list result;
|
||||
// call original function
|
||||
vector<string> v = names();
|
||||
// put all the strings inside the python list
|
||||
vector<string>::iterator it;
|
||||
for (it = v.begin(); it != v.end(); ++it){
|
||||
result.append(*it);
|
||||
}
|
||||
return result;
|
||||
}
|
||||
|
||||
BOOST_PYTHON_MODULE(test)
|
||||
{
|
||||
def("names", &names_wrapper);
|
||||
}
|
||||
|
||||
Nice heh? Pyste supports this mechanism too. You declare the [^names_wrapper]
|
||||
function in a header named "[^test_wrappers.h]" and in the interface file:
|
||||
|
||||
Include("test_wrappers.h")
|
||||
names = Function("names", "test.h")
|
||||
set_wrapper(names, "names_wrapper")
|
||||
|
||||
You can optionally declare the function in the interface file itself:
|
||||
|
||||
names_wrapper = Wrapper("names_wrapper",
|
||||
"""
|
||||
list names_wrapper()
|
||||
{
|
||||
// code to call name() and convert the vector to a list...
|
||||
}
|
||||
""")
|
||||
names = Function("names", "test.h")
|
||||
set_wrapper(names, names_wrapper)
|
||||
|
||||
The same mechanism can be used with member functions too. Just remember that
|
||||
the first parameter of wrappers for member functions is a pointer to the
|
||||
class, as in:
|
||||
|
||||
struct C
|
||||
{
|
||||
std::vector<std::string> names();
|
||||
}
|
||||
|
||||
list names_wrapper(C* c)
|
||||
{
|
||||
// same as before, calling c->names() and converting result to a list
|
||||
}
|
||||
|
||||
And then in the interface file:
|
||||
|
||||
C = Class("C", "test.h")
|
||||
set_wrapper(C.names, "names_wrapper")
|
||||
|
||||
[blurb
|
||||
[$theme/note.gif]Even though Boost.Python accepts either a pointer or a
|
||||
reference to the class in wrappers for member functions as the first parameter,
|
||||
Pyste expects them to be a [*pointer]. Doing otherwise will prevent your
|
||||
code to compile when you set a wrapper for a virtual member function.
|
||||
]
|
||||
|
||||
[page:1 Exporting An Entire Header]
|
||||
|
||||
Pyste also supports a mechanism to export all declarations found in a header
|
||||
file. Suppose again our file, [^hello.h]:
|
||||
|
||||
struct World
|
||||
{
|
||||
World(std::string msg): msg(msg) {}
|
||||
void set(std::string msg) { this->msg = msg; }
|
||||
std::string greet() { return msg; }
|
||||
std::string msg;
|
||||
};
|
||||
|
||||
enum choice { red, blue };
|
||||
|
||||
void show(choice c) { std::cout << "value: " << (int)c << std::endl; }
|
||||
|
||||
You can just use the [^AllFromHeader] construct:
|
||||
|
||||
hello = AllFromHeader("hello.h")
|
||||
|
||||
this will export all the declarations found in [^hello.h], which is equivalent
|
||||
to write:
|
||||
|
||||
Class("World", "hello.h")
|
||||
Enum("choice", "hello.h")
|
||||
Function("show", "hello.h")
|
||||
|
||||
Note that you can still use the functions [^rename], [^set_policy], [^exclude], etc. Just access
|
||||
the members of the header object like this:
|
||||
|
||||
rename(hello.World.greet, "Greet")
|
||||
exclude(hello.World.set, "Set")
|
||||
|
||||
|
||||
[page:1 Smart Pointers]
|
||||
|
||||
Pyste for now has manual support for smart pointers. Suppose:
|
||||
|
||||
struct C
|
||||
{
|
||||
int value;
|
||||
};
|
||||
|
||||
boost::shared_ptr<C> newC(int value)
|
||||
{
|
||||
boost::shared_ptr<C> c( new C() );
|
||||
c->value = value;
|
||||
return c;
|
||||
}
|
||||
|
||||
void printC(boost::shared_ptr<C> c)
|
||||
{
|
||||
std::cout << c->value << std::endl;
|
||||
}
|
||||
|
||||
To make [^newC] and [^printC] work correctly, you have to tell Pyste that a
|
||||
convertor for [^boost::shared_ptr<C>] is needed.
|
||||
|
||||
C = Class('C', 'C.h')
|
||||
use_shared_ptr(C)
|
||||
Function('newC', 'C.h')
|
||||
Function('printC', 'C.h')
|
||||
|
||||
For [^std::auto_ptr]'s, use the function [^use_auto_ptr].
|
||||
|
||||
This system is temporary, and in the future the converters will automatically be
|
||||
exported if needed, without the need to tell Pyste about them explicitly.
|
||||
|
||||
[h2 Holders]
|
||||
|
||||
If only the converter for the smart pointers is not enough and you need to
|
||||
specify the smart pointer as the holder for a class, use the functions
|
||||
[^hold_with_shared_ptr] and [^hold_with_auto_ptr]:
|
||||
|
||||
C = Class('C', 'C.h')
|
||||
hold_with_shared_ptr(C)
|
||||
Function('newC', 'C.h')
|
||||
Function('printC', 'C.h')
|
||||
|
||||
[page:1 Global Variables]
|
||||
|
||||
To export global variables, use the [^Var] construct:
|
||||
|
||||
Var("myglobal", "foo.h")
|
||||
|
||||
Beware of non-const global variables: changes in Python won't reflect in C++!
|
||||
If you really must change them in Python, you will have to write some accessor
|
||||
functions, and export those.
|
||||
|
||||
[page:1 Adding New Methods]
|
||||
|
||||
Suppose that you want to add a function to a class, turning it into a member
|
||||
function:
|
||||
|
||||
struct World
|
||||
{
|
||||
void set(std::string msg) { this->msg = msg; }
|
||||
std::string msg;
|
||||
};
|
||||
|
||||
std::string greet(World& w)
|
||||
{
|
||||
return w.msg;
|
||||
}
|
||||
|
||||
Here, we want to make [^greet] work as a member function of the class [^World]. We do
|
||||
that using the [^add_method] construct:
|
||||
|
||||
W = Class("World", "hello.h")
|
||||
add_method(W, "greet")
|
||||
|
||||
Notice also that then you can rename it, set its policy, just like a regular
|
||||
member function:
|
||||
|
||||
rename(W.greet, 'Greet')
|
||||
|
||||
Now from Python:
|
||||
|
||||
>>> import hello
|
||||
>>> w = hello.World()
|
||||
>>> w.set('Ni')
|
||||
>>> w.greet()
|
||||
'Ni'
|
||||
>>> print 'Oh no! The knights who say Ni!'
|
||||
Oh no! The knights who say Ni!

</span></pre></code>
|
||||
<p>
|
||||
You can exclude functions, classes, member functions, attributes, etc, in the same way,
|
||||
with the function <tt>exclude</tt>:</p>
|
||||
<code><pre>
|
||||
<span class=identifier>exclude</span><span class=special>(</span><span class=identifier>World</span><span class=special>.</span><span class=identifier>greet</span><span class=special>)
|
||||
</span><span class=identifier>exclude</span><span class=special>(</span><span class=identifier>World</span><span class=special>.</span><span class=identifier>msg</span><span class=special>)
|
||||
</span></pre></code>
|
||||
<p>
|
||||
To access the operators of a class, access the member <tt>operator</tt> like this
|
||||
(supposing that <tt>C</tt> is a class being exported):</p>
|
||||
<code><pre>
|
||||
<span class=identifier>exclude</span><span class=special>(</span><span class=identifier>C</span><span class=special>.</span><span class=keyword>operator</span><span class=special>[</span><span class=literal>'+'</span><span class=special>])
|
||||
</span><span class=identifier>exclude</span><span class=special>(</span><span class=identifier>C</span><span class=special>.</span><span class=keyword>operator</span><span class=special>[</span><span class=literal>'*'</span><span class=special>])
|
||||
</span><span class=identifier>exclude</span><span class=special>(</span><span class=identifier>C</span><span class=special>.</span><span class=keyword>operator</span><span class=special>[</span><span class=literal>'<<'</span><span class=special>])
|
||||
</span></pre></code>
|
||||
<p>
|
||||
The string inside the brackets is the same as the name of the operator in C++.<br></p>
|
||||
<a name="virtual_member_functions"></a><h2>Virtual Member Functions</h2><p>
|
||||
Pyste automatically generates wrappers for virtual member functions, but you
|
||||
may want to disable this behaviour (for performance reasons, or to let the
|
||||
code more clean) if you do not plan to override the functions in Python. To do
|
||||
this, use the function <tt>final</tt>:</p>
|
||||
<code><pre>
|
||||
<span class=identifier>C </span><span class=special>= </span><span class=identifier>Class</span><span class=special>(</span><span class=literal>'C'</span><span class=special>, </span><span class=literal>'C.h'</span><span class=special>)
|
||||
</span><span class=identifier>final</span><span class=special>(</span><span class=identifier>C</span><span class=special>.</span><span class=identifier>foo</span><span class=special>) </span>##<span class=identifier>C</span><span class=special>::</span><span class=identifier>foo </span><span class=identifier>is </span><span class=identifier>a </span><span class=keyword>virtual </span><span class=identifier>member </span><span class=identifier>function
|
||||
</span></pre></code>
|
||||
<p>
|
||||
No virtual wrapper code will be generated for the virtual member function
|
||||
C::foo that way.</p>

<a name="ok__now_what_"></a><h2>Ok, now what?</h2><p>
|
||||
Well, now let's fire it up:</p>
|
||||
<code><pre>
|
||||
|
||||
>python pyste.py
|
||||
|
||||
Pyste version 0.6.5
|
||||
|
||||
Usage:
|
||||
pyste [options] --module=<name> interface-files
|
||||
|
||||
where options are:
|
||||
-I <path> add an include path
|
||||
-D <symbol> define symbol
|
||||
--multiple create various cpps (one for each pyste file), instead
|
||||
of only one (useful during development)
|
||||
--out specify output filename (default: <module>.cpp)
|
||||
in --multiple mode, this will be a directory
|
||||
--no-using do not declare "using namespace boost";
|
||||
use explicit declarations instead
|
||||
--pyste-ns=<name> set the namespace where new types will be declared;
|
||||
default is the empty namespace
|
||||
--debug writes the xml for each file parsed in the current
|
||||
directory
|
||||
-h, --help print this help and exit
|
||||
-v, --version print version information
|
||||
|
||||
</pre></code><p>
|
||||
Options explained:</p>
|
||||
<p>
|
||||
The <tt>-I</tt> and <tt>-D</tt> are preprocessor flags, which are needed by <a href="http://www.gccxml.org">
|
||||
GCCXML</a> to parse
|
||||
the header files correctly and by Pyste to find the header files declared in the
|
||||
interface files.</p>
|
||||
<p>
|
||||
<tt>--multiple</tt> tells Pyste to generate multiple cpps for this module (one for
|
||||
each header parsed) in the directory named by <tt>--out</tt>, instead of the usual
|
||||
single cpp file. This mode is useful during development of a binding, because
|
||||
you are constantly changing source files, re-generating the bindings and
|
||||
recompiling. This saves a lot of time in compiling.</p>
|
||||
<p>
|
||||
<tt>--out</tt> names the output file (default: <tt><module>.cpp</tt>), or in multiple mode,
|
||||
names a output directory for the files (default: <tt><module></tt>).</p>
|
||||
<p>
|
||||
<tt>--no-using</tt> tells Pyste to don't declare "<tt>using namespace boost;</tt>" in the
|
||||
generated cpp, using the namespace boost::python explicitly in all declarations.
|
||||
Use only if you're having a name conflict in one of the files.</p>
|
||||
<p>
|
||||
Use <tt>--pyste-ns</tt> to change the namespace where new types are declared (for
|
||||
instance, the virtual wrappers). Use only if you are having any problems. By
|
||||
default, Pyste uses the empty namespace.</p>
|
||||
<p>
|
||||
<tt>--debug</tt> will write in the current directory a xml file as outputted by <a href="http://www.gccxml.org">
|
||||
GCCXML</a>
|
||||
for each header parsed. Useful for bug reports.</p>
|
||||
<p>
|
||||
<tt>-h, --help, -v, --version</tt> are self-explaining, I believe. ;)</p>
|
||||
<p>
|
||||
So, the usage is simple enough:</p>
|
||||
<code><pre>>python pyste.py --module=mymodule file.pyste file2.pyste ...</pre></code><p>
|
||||
will generate a file <tt>mymodule.cpp</tt> in the same dir where the command was
|
||||
executed. Now you can compile the file using the same instructions of the
|
||||
<a href="../../doc/tutorial/doc/building_hello_world.html">
|
||||
tutorial</a>. Or, if you prefer:</p>
|
||||
<code><pre>>python pyste.py --module=mymodule --multiple file.pyste file2.pyste ...</pre></code><p>
|
||||
will create a directory named "mymodule" in the current directory, and will
|
||||
generate a bunch of cpp files, one for each header exported. You can then
|
||||
compile them all into a single shared library (or dll).</p>
|
||||
<a name="wait____how_do_i_set_those_i_and_d_flags_"></a><h2>Wait... how do I set those I and D flags?</h2><p>
|
||||
Don't worry: normally <a href="http://www.gccxml.org">
|
||||
GCCXML</a> is already configured correctly for your plataform,
|
||||
so the search path to the standard libraries and the standard defines should
|
||||
already be set. You only have to set the paths to other libraries that your code
|
||||
needs, like Boost, for example.</p>
|
||||
<p>
|
||||
Plus, Pyste automatically uses the contents of the environment variable
|
||||
<tt>INCLUDE</tt> if it exists. Visual C++ users should run the <tt>Vcvars32.bat</tt> file,
|
||||
which for Visual C++ 6 is normally located at:</p>
|
||||
<code><pre>
|
||||
<span class=identifier>C</span><span class=special>:\</span><span class=identifier>Program </span><span class=identifier>Files</span><span class=special>\</span><span class=identifier>Microsoft </span><span class=identifier>Visual </span><span class=identifier>Studio</span><span class=special>\</span><span class=identifier>VC98</span><span class=special>\</span><span class=identifier>bin</span><span class=special>\</span><span class=identifier>Vcvars32</span><span class=special>.</span><span class=identifier>bat
|
||||
</span></pre></code>
|
||||
<p>
|
||||
with that, you should have little trouble setting up the flags.</p>

Although you don't have to install <a href="http://psyco.sourceforge.net/">

Psyco</a> to use Pyste, if you do, Pyste will make use of it to speed up the wrapper generation. Speed ups of 30% can be achieved, so it's highly recommended.

|

<p>
|

To make <tt>newC</tt> and <tt>printC</tt> work correctly, you have to tell Pyste that a

convertor for <tt>boost::shared_ptr<C></tt> is needed.</p>
|
||||
<code><pre>
|
||||
<span class=identifier>C </span><span class=special>= </span><span class=identifier>Class</span><span class=special>(</span><span class=literal>'C'</span><span class=special>, </span><span class=literal>'C.h'</span><span class=special>)

|
||||
</span></pre></code>
|
||||
<p>
|
||||
For <tt>std::auto_ptr</tt>'s, use the function <tt>use_auto_ptr</tt>.</p>
|
||||
<p>
|
||||
This system is temporary, and in the future the converters will automatically be
|
||||
exported if needed, without the need to tell Pyste about them explicitly.</p>
|
||||
<a name="holders"></a><h2>Holders</h2><p>
|

If only the converter for the smart pointers is not enough and you need to

specify the smart pointer as the holder for a class, use the functions

<tt>hold_with_shared_ptr</tt> and <tt>hold_with_auto_ptr</tt>:</p>

Template classes can easily be exported too, but you can't export the template
|
||||
itself... you have to export instantiations of it! So, if you want to export a

<tt>std::vector</tt>, you will have to export vectors of int, doubles, etc.</p>

||||
<p>
|
||||
Suppose we have this code:</p>
|
||||
<code><pre>
|
||||
<span class=keyword>template </span><span class=special><</span><span class=keyword>class </span><span class=identifier>T</span><span class=special>>
|
||||
</span><span class=keyword>struct </span><span class=identifier>Point
|
||||
</span><span class=special>{
|
||||
</span><span class=identifier>T </span><span class=identifier>x</span><span class=special>;
|
||||
</span><span class=identifier>T </span><span class=identifier>y</span><span class=special>;
|
||||
};
|
||||
</span></pre></code>
|
||||
<p>
|
||||
And we want to export <tt>Point</tt>s of int and double:</p>
|
||||
<code><pre>
|
||||
<span class=identifier>Point </span><span class=special>= </span><span class=identifier>Template</span><span class=special>(</span><span class=string>"Point"</span><span class=special>, </span><span class=string>"point.h"</span><span class=special>)
|
||||
</span><span class=identifier>Point</span><span class=special>(</span><span class=string>"int"</span><span class=special>)
|
||||
</span><span class=identifier>Point</span><span class=special>(</span><span class=string>"double"</span><span class=special>)
|
||||
</span></pre></code>
|
||||
<p>
|
||||
Pyste will assign default names for each instantiation. In this example, those
|
||||
would be "<tt>Point_int</tt>" and "<tt>Point_double</tt>", but most of the time users will want to
|
||||
rename the instantiations:</p>
|
||||
<code><pre>
|
||||
<span class=identifier>Point</span><span class=special>(</span><span class=string>"int"</span><span class=special>, </span><span class=string>"IPoint"</span><span class=special>) // </span><span class=identifier>renames </span><span class=identifier>the </span><span class=identifier>instantiation
|
||||
</span><span class=identifier>double_inst </span><span class=special>= </span><span class=identifier>Point</span><span class=special>(</span><span class=string>"double"</span><span class=special>) // </span><span class=identifier>another </span><span class=identifier>way </span><span class=identifier>to </span><span class=keyword>do </span><span class=identifier>the </span><span class=identifier>same
|
||||
</span><span class=identifier>rename</span><span class=special>(</span><span class=identifier>double_inst</span><span class=special>, </span><span class=string>"DPoint"</span><span class=special>)
|
||||
</span></pre></code>
|
||||
<p>
|
||||
Note that you can rename, exclude, set policies, etc, in the <tt>Template</tt> object
|
||||
like you would do with a <tt>Function</tt> or a <tt>Class</tt>. This changes affect all
|
||||
<b>future</b> instantiations:</p>
|
||||
<code><pre>
|
||||
<span class=identifier>Point </span><span class=special>= </span><span class=identifier>Template</span><span class=special>(</span><span class=string>"Point"</span><span class=special>, </span><span class=string>"point.h"</span><span class=special>)
|
||||
</span><span class=identifier>Point</span><span class=special>(</span><span class=string>"float"</span><span class=special>, </span><span class=string>"FPoint"</span><span class=special>) // </span><span class=identifier>will </span><span class=identifier>have </span><span class=identifier>x </span><span class=keyword>and </span><span class=identifier>y </span><span class=identifier>as </span><span class=identifier>data </span><span class=identifier>members
|
||||
</span><span class=identifier>rename</span><span class=special>(</span><span class=identifier>Point</span><span class=special>.</span><span class=identifier>x</span><span class=special>, </span><span class=string>"X"</span><span class=special>)
|
||||
</span><span class=identifier>rename</span><span class=special>(</span><span class=identifier>Point</span><span class=special>.</span><span class=identifier>y</span><span class=special>, </span><span class=string>"Y"</span><span class=special>)
|
||||
</span><span class=identifier>Point</span><span class=special>(</span><span class=string>"int"</span><span class=special>, </span><span class=string>"IPoint"</span><span class=special>) // </span><span class=identifier>will </span><span class=identifier>have </span><span class=identifier>X </span><span class=keyword>and </span><span class=identifier>Y </span><span class=identifier>as </span><span class=identifier>data </span><span class=identifier>members
|
||||
</span><span class=identifier>Point</span><span class=special>(</span><span class=string>"double"</span><span class=special>, </span><span class=string>"DPoint"</span><span class=special>) // </span><span class=identifier>also </span><span class=identifier>will </span><span class=identifier>have </span><span class=identifier>X </span><span class=keyword>and </span><span class=identifier>Y </span><span class=identifier>as </span><span class=identifier>data </span><span class=identifier>member
|
||||
</span></pre></code>
|
||||
<p>
|
||||
If you want to change a option of a particular instantiation, you can do so:</p>
|
||||
<code><pre>
|
||||
<span class=identifier>Point </span><span class=special>= </span><span class=identifier>Template</span><span class=special>(</span><span class=string>"Point"</span><span class=special>, </span><span class=string>"point.h"</span><span class=special>)
|

|

|

</span><span class=identifier>rename</span><span class=special>(</span><span class=identifier>d_inst</span><span class=special>.</span><span class=identifier>x</span><span class=special>, </span><span class=string>"X"</span><span class=special>) // </span><span class=identifier>only </span><span class=identifier>DPoint </span><span class=identifier>is </span><span class=identifier>affect </span><span class=identifier>by </span><span class=keyword>this </span><span class=identifier>renames</span><span class=special>,
|

</span><span class=identifier>rename</span><span class=special>(</span><span class=identifier>d_inst</span><span class=special>.</span><span class=identifier>y</span><span class=special>, </span><span class=string>"Y"</span><span class=special>) // </span><span class=identifier>IPoint </span><span class=identifier>stays </span><span class=identifier>intact

When you want to instantiate a template with more than one type, you can pass

either a string with the types separated by whitespace, or a list of strings

("int double" or ["int", "double"] would both work).

The interface files are the heart of Pyste. The user creates one or more
|
||||
interface files declaring the classes and functions he wants to export, and then
|
||||
invokes Pyste passing the interface files to it. Pyste then generates a single
|
||||
cpp file with <a href="../../index.html">
|
||||
Boost.Python</a> code, with all the classes and functions exported.</p>
|
||||
<p>
|
||||
Besides declaring the classes and functions, the user has a number of other
|
||||
options, like renaming e excluding classes and member functionis. Those are
|
||||
explained later on.</p>
|
||||
<a name="basics"></a><h2>Basics</h2><p>
|
||||
Suppose we have a class and some functions that we want to expose to Python
|
||||
declared in the header <tt>hello.h</tt>:</p>
|
||||
<code><pre>
|
||||
<span class=keyword>struct </span><span class=identifier>World
|
||||
</span><span class=special>{
|
||||
</span><span class=identifier>World</span><span class=special>(</span><span class=identifier>std</span><span class=special>::</span><span class=identifier>string </span><span class=identifier>msg</span><span class=special>): </span><span class=identifier>msg</span><span class=special>(</span><span class=identifier>msg</span><span class=special>) {}

</span><span class=identifier>std</span><span class=special>::</span><span class=identifier>string </span><span class=identifier>greet</span><span class=special>() { </span><span class=keyword>return </span><span class=identifier>msg</span><span class=special>; }

</span><span class=identifier>std</span><span class=special>::</span><span class=identifier>string </span><span class=identifier>msg</span><span class=special>;
|
||||
};
|
||||
|
||||
</span><span class=keyword>enum </span><span class=identifier>choice </span><span class=special>{ </span><span class=identifier>red</span><span class=special>, </span><span class=identifier>blue </span><span class=special>};
|

|

</span><span class=keyword>namespace </span><span class=identifier>test </span><span class=special>{
|

</span><span class=keyword>void </span><span class=identifier>show</span><span class=special>(</span><span class=identifier>choice </span><span class=identifier>c</span><span class=special>) { </span><span class=identifier>std</span><span class=special>::</span><span class=identifier>cout </span><span class=special><< </span><span class=string>"value: " </span><span class=special><< (</span><span class=keyword>int</span><span class=special>)</span><span class=identifier>c </span><span class=special><< </span><span class=identifier>std</span><span class=special>::</span><span class=identifier>endl</span><span class=special>; }
|
||||
|
||||
}
|
||||
</span></pre></code>
|
||||
<p>
|
||||
We create a file named <tt>hello.pyste</tt> and create instances of the classes
|
||||
<tt>Function</tt>, <tt>Class</tt> and <tt>Enum</tt>:</p>
|
||||
<code><pre>
|
||||
<span class=identifier>Function</span><span class=special>(</span><span class=string>"test::show"</span><span class=special>, </span><span class=string>"hello.h"</span><span class=special>)
|
||||
</span><span class=identifier>Class</span><span class=special>(</span><span class=string>"World"</span><span class=special>, </span><span class=string>"hello.h"</span><span class=special>)
|

</span><span class=identifier>Enum</span><span class=special>(</span><span class=string>"choice"</span><span class=special>, </span><span class=string>"hello.h"</span><span class=special>)
|
||||
</span></pre></code>
|
||||
<p>
|
||||
That will expose the class, the free function and the enum found in <tt>hello.h</tt>. </p>

Suppose you have this function:</p>
|
||||
<code><pre>
|
||||
<span class=identifier>std</span><span class=special>::</span><span class=identifier>vector</span><span class=special><</span><span class=identifier>std</span><span class=special>::</span><span class=identifier>string</span><span class=special>> </span><span class=identifier>names</span><span class=special>();
|
||||
</span></pre></code>
|
||||
<p>
|
||||
But you don't want to export <tt>std::vector<std::string></tt>, you want this function
|
||||
to return a python list of strings. <a href="../../index.html">
|
||||
Boost.Python</a> has excellent support for
|
||||
that:</p>
|
||||
<code><pre>
|
||||
<span class=identifier>list </span><span class=identifier>names_wrapper</span><span class=special>()
|
||||
{
|
||||
</span><span class=identifier>list </span><span class=identifier>result</span><span class=special>;
|
||||
// </span><span class=identifier>call </span><span class=identifier>original </span><span class=identifier>function
|
||||
</span><span class=identifier>vector</span><span class=special><</span><span class=identifier>string</span><span class=special>> </span><span class=identifier>v </span><span class=special>= </span><span class=identifier>names</span><span class=special>();
|
||||
// </span><span class=identifier>put </span><span class=identifier>all </span><span class=identifier>the </span><span class=identifier>strings </span><span class=identifier>inside </span><span class=identifier>the </span><span class=identifier>python </span><span class=identifier>list
|
||||
</span><span class=identifier>vector</span><span class=special><</span><span class=identifier>string</span><span class=special>>::</span><span class=identifier>iterator </span><span class=identifier>it</span><span class=special>;
|
||||
</span><span class=keyword>for </span><span class=special>(</span><span class=identifier>it </span><span class=special>= </span><span class=identifier>v</span><span class=special>.</span><span class=identifier>begin</span><span class=special>(); </span><span class=identifier>it </span><span class=special>!= </span><span class=identifier>v</span><span class=special>.</span><span class=identifier>end</span><span class=special>(); ++</span><span class=identifier>it</span><span class=special>){
|
||||
</span><span class=identifier>result</span><span class=special>.</span><span class=identifier>append</span><span class=special>(*</span><span class=identifier>it</span><span class=special>);
|
||||
}
|
||||
</span><span class=keyword>return </span><span class=identifier>result</span><span class=special>;
|
||||
}
|
||||
|
||||
</span><span class=identifier>BOOST_PYTHON_MODULE</span><span class=special>(</span><span class=identifier>test</span><span class=special>)
|
||||
{
|
||||
</span><span class=identifier>def</span><span class=special>(</span><span class=string>"names"</span><span class=special>, &</span><span class=identifier>names_wrapper</span><span class=special>);
|
||||
}
|
||||
</span></pre></code>
|
||||
<p>
|
||||
Nice heh? Pyste supports this mechanism too. You declare the <tt>names_wrapper</tt>
|
||||
function in a header named "<tt>test_wrappers.h</tt>" and in the interface file:</p>
|
||||
<code><pre>
|
||||
<span class=identifier>Include</span><span class=special>(</span><span class=string>"test_wrappers.h"</span><span class=special>)
|
||||
</span><span class=identifier>names </span><span class=special>= </span><span class=identifier>Function</span><span class=special>(</span><span class=string>"names"</span><span class=special>, </span><span class=string>"test.h"</span><span class=special>)
|
||||
</span><span class=identifier>set_wrapper</span><span class=special>(</span><span class=identifier>names</span><span class=special>, </span><span class=string>"names_wrapper"</span><span class=special>)
|
||||
</span></pre></code>
|
||||
<p>
|
||||
You can optionally declare the function in the interface file itself:</p>
|
||||
<code><pre>
|
||||
<span class=identifier>names_wrapper </span><span class=special>= </span><span class=identifier>Wrapper</span><span class=special>(</span><span class=string>"names_wrapper"</span><span class=special>,
|
||||
</span><span class=string>""</span><span class=string>"
|
||||
list names_wrapper()
|
||||
{
|
||||
// code to call name() and convert the vector to a list...
|
||||
}
|
||||
"</span><span class=string>""</span><span class=special>)
|
||||
</span><span class=identifier>names </span><span class=special>= </span><span class=identifier>Function</span><span class=special>(</span><span class=string>"names"</span><span class=special>, </span><span class=string>"test.h"</span><span class=special>)
|
||||
</span><span class=identifier>set_wrapper</span><span class=special>(</span><span class=identifier>names</span><span class=special>, </span><span class=identifier>names_wrapper</span><span class=special>)
|
||||
</span></pre></code>
|
||||
<p>
|
||||
The same mechanism can be used with member functions too. Just remember that
|
||||
the first parameter of wrappers for member functions is a pointer to the
|
||||
class, as in:</p>
|
||||
<code><pre>
|
||||
<span class=keyword>struct </span><span class=identifier>C
|
||||
</span><span class=special>{
|
||||
</span><span class=identifier>std</span><span class=special>::</span><span class=identifier>vector</span><span class=special><</span><span class=identifier>std</span><span class=special>::</span><span class=identifier>string</span><span class=special>> </span><span class=identifier>names</span><span class=special>();
|
||||
}
|
||||
|
||||
</span><span class=identifier>list </span><span class=identifier>names_wrapper</span><span class=special>(</span><span class=identifier>C</span><span class=special>* </span><span class=identifier>c</span><span class=special>)
|
||||
{
|
||||
// </span><span class=identifier>same </span><span class=identifier>as </span><span class=identifier>before</span><span class=special>, </span><span class=identifier>calling </span><span class=identifier>c</span><span class=special>-></span><span class=identifier>names</span><span class=special>() </span><span class=keyword>and </span><span class=identifier>converting </span><span class=identifier>result </span><span class=identifier>to </span><span class=identifier>a </span><span class=identifier>list
|
||||
</span><span class=special>}
|
||||
</span></pre></code>
|
||||
<p>
|
||||
And then in the interface file:</p>
|
||||
<code><pre>
|
||||
<span class=identifier>C </span><span class=special>= </span><span class=identifier>Class</span><span class=special>(</span><span class=string>"C"</span><span class=special>, </span><span class=string>"test.h"</span><span class=special>)
|
||||
</span><span class=identifier>set_wrapper</span><span class=special>(</span><span class=identifier>C</span><span class=special>.</span><span class=identifier>names</span><span class=special>, </span><span class=string>"names_wrapper"</span><span class=special>)
|
||||
</span></pre></code>
