That means, -without an explicit return value policy, lvalue references will be copied and -pointers will be managed by pybind11. In order to avoid copying, you should -explicitly specify an appropriate return value policy, as in the following -example: - -.. code-block:: cpp - - class MyClass { - Eigen::MatrixXd big_mat = Eigen::MatrixXd::Zero(10000, 10000); - public: - Eigen::MatrixXd &getMatrix() { return big_mat; } - const Eigen::MatrixXd &viewMatrix() { return big_mat; } - }; - - // Later, in binding code: - py::class_(m, "MyClass") - .def(py::init<>()) - .def("copy_matrix", &MyClass::getMatrix) // Makes a copy! - .def("get_matrix", &MyClass::getMatrix, py::return_value_policy::reference_internal) - .def("view_matrix", &MyClass::viewMatrix, py::return_value_policy::reference_internal) - ; - -.. code-block:: python - - a = MyClass() - m = a.get_matrix() # flags.writeable = True, flags.owndata = False - v = a.view_matrix() # flags.writeable = False, flags.owndata = False - c = a.copy_matrix() # flags.writeable = True, flags.owndata = True - # m[5,6] and v[5,6] refer to the same element, c[5,6] does not. - -Note in this example that ``py::return_value_policy::reference_internal`` is -used to tie the life of the MyClass object to the life of the returned arrays. - -You may also return an ``Eigen::Ref``, ``Eigen::Map`` or other map-like Eigen -object (for example, the return value of ``matrix.block()`` and related -methods) that map into a dense Eigen type. When doing so, the default -behaviour of pybind11 is to simply reference the returned data: you must take -care to ensure that this data remains valid! You may ask pybind11 to -explicitly *copy* such a return value by using the -``py::return_value_policy::copy`` policy when binding the function. You may -also use ``py::return_value_policy::reference_internal`` or a -``py::keep_alive`` to ensure the data stays valid as long as the returned numpy -array does. - -When returning such a reference of map, pybind11 additionally respects the -readonly-status of the returned value, marking the numpy array as non-writeable -if the reference or map was itself read-only. - -.. note:: - - Sparse types are always copied when returned. - -.. _storage_orders: - -Storage orders -============== - -Passing arguments via ``Eigen::Ref`` has some limitations that you must be -aware of in order to effectively pass matrices by reference. First and -foremost is that the default ``Eigen::Ref`` class requires -contiguous storage along columns (for column-major types, the default in Eigen) -or rows if ``MatrixType`` is specifically an ``Eigen::RowMajor`` storage type. -The former, Eigen's default, is incompatible with ``numpy``'s default row-major -storage, and so you will not be able to pass numpy arrays to Eigen by reference -without making one of two changes. - -(Note that this does not apply to vectors (or column or row matrices): for such -types the "row-major" and "column-major" distinction is meaningless). - -The first approach is to change the use of ``Eigen::Ref`` to the -more general ``Eigen::Ref>`` (or similar type with a fully dynamic stride type in the -third template argument). Since this is a rather cumbersome type, pybind11 -provides a ``py::EigenDRef`` type alias for your convenience (along -with EigenDMap for the equivalent Map, and EigenDStride for just the stride -type). - -This type allows Eigen to map into any arbitrary storage order. This is not -the default in Eigen for performance reasons: contiguous storage allows -vectorization that cannot be done when storage is not known to be contiguous at -compile time. The default ``Eigen::Ref`` stride type allows non-contiguous -storage along the outer dimension (that is, the rows of a column-major matrix -or columns of a row-major matrix), but not along the inner dimension. - -This type, however, has the added benefit of also being able to map numpy array -slices. For example, the following (contrived) example uses Eigen with a numpy -slice to multiply by 2 all coefficients that are both on even rows (0, 2, 4, -...) and in columns 2, 5, or 8: - -.. code-block:: cpp - - m.def("scale", [](py::EigenDRef m, double c) { m *= c; }); - -.. code-block:: python - - # a = np.array(...) - scale_by_2(myarray[0::2, 2:9:3]) - -The second approach to avoid copying is more intrusive: rearranging the -underlying data types to not run into the non-contiguous storage problem in the -first place. In particular, that means using matrices with ``Eigen::RowMajor`` -storage, where appropriate, such as: - -.. code-block:: cpp - - using RowMatrixXd = Eigen::Matrix; - // Use RowMatrixXd instead of MatrixXd - -Now bound functions accepting ``Eigen::Ref`` arguments will be -callable with numpy's (default) arrays without involving a copying. - -You can, alternatively, change the storage order that numpy arrays use by -adding the ``order='F'`` option when creating an array: - -.. code-block:: python - - myarray = np.array(source, order="F") - -Such an object will be passable to a bound function accepting an -``Eigen::Ref`` (or similar column-major Eigen type). - -One major caveat with this approach, however, is that it is not entirely as -easy as simply flipping all Eigen or numpy usage from one to the other: some -operations may alter the storage order of a numpy array. For example, ``a2 = -array.transpose()`` results in ``a2`` being a view of ``array`` that references -the same data, but in the opposite storage order! - -While this approach allows fully optimized vectorized calculations in Eigen, it -cannot be used with array slices, unlike the first approach. - -When *returning* a matrix to Python (either a regular matrix, a reference via -``Eigen::Ref<>``, or a map/block into a matrix), no special storage -consideration is required: the created numpy array will have the required -stride that allows numpy to properly interpret the array, whatever its storage -order. - -Failing rather than copying -=========================== - -The default behaviour when binding ``Eigen::Ref`` Eigen -references is to copy matrix values when passed a numpy array that does not -conform to the element type of ``MatrixType`` or does not have a compatible -stride layout. If you want to explicitly avoid copying in such a case, you -should bind arguments using the ``py::arg().noconvert()`` annotation (as -described in the :ref:`nonconverting_arguments` documentation). - -The following example shows an example of arguments that don't allow data -copying to take place: - -.. code-block:: cpp - - // The method and function to be bound: - class MyClass { - // ... - double some_method(const Eigen::Ref &matrix) { /* ... */ } - }; - float some_function(const Eigen::Ref &big, - const Eigen::Ref &small) { - // ... - } - - // The associated binding code: - using namespace pybind11::literals; // for "arg"_a - py::class_(m, "MyClass") - // ... other class definitions - .def("some_method", &MyClass::some_method, py::arg().noconvert()); - - m.def("some_function", &some_function, - "big"_a.noconvert(), // <- Don't allow copying for this arg - "small"_a // <- This one can be copied if needed - ); - -With the above binding code, attempting to call the the ``some_method(m)`` -method on a ``MyClass`` object, or attempting to call ``some_function(m, m2)`` -will raise a ``RuntimeError`` rather than making a temporary copy of the array. -It will, however, allow the ``m2`` argument to be copied into a temporary if -necessary. - -Note that explicitly specifying ``.noconvert()`` is not required for *mutable* -Eigen references (e.g. ``Eigen::Ref`` without ``const`` on the -``MatrixXd``): mutable references will never be called with a temporary copy. - -Vectors versus column/row matrices -================================== - -Eigen and numpy have fundamentally different notions of a vector. In Eigen, a -vector is simply a matrix with the number of columns or rows set to 1 at -compile time (for a column vector or row vector, respectively). NumPy, in -contrast, has comparable 2-dimensional 1xN and Nx1 arrays, but *also* has -1-dimensional arrays of size N. - -When passing a 2-dimensional 1xN or Nx1 array to Eigen, the Eigen type must -have matching dimensions: That is, you cannot pass a 2-dimensional Nx1 numpy -array to an Eigen value expecting a row vector, or a 1xN numpy array as a -column vector argument. - -On the other hand, pybind11 allows you to pass 1-dimensional arrays of length N -as Eigen parameters.

It does, -however, require the compiler to generate at least as many methods (and -possibly more, if both pure virtual and overridden pure virtual methods are -exposed, as above). - -The classes are then registered with pybind11 using: - -.. code-block:: cpp - - py::class_> animal(m, "Animal"); - py::class_> dog(m, "Dog"); - py::class_> husky(m, "Husky"); - // ... add animal, dog, husky definitions - -Note that ``Husky`` did not require a dedicated trampoline template class at -all, since it neither declares any new virtual methods nor provides any pure -virtual method implementations. - -With either the repeated-virtuals or templated trampoline methods in place, you -can now create a python class that inherits from ``Dog``: - -.. code-block:: python - - class ShihTzu(Dog): - def bark(self): - return "yip!" - -.. seealso:: - - See the file :file:`tests/test_virtual_functions.cpp` for complete examples - using both the duplication and templated trampoline approaches. - -.. _extended_aliases: - -Extended trampoline class functionality -======================================= - -.. _extended_class_functionality_forced_trampoline: - -Forced trampoline class initialisation --------------------------------------- -The trampoline classes described in the previous sections are, by default, only -initialized when needed. More specifically, they are initialized when a python -class actually inherits from a registered type (instead of merely creating an -instance of the registered type), or when a registered constructor is only -valid for the trampoline class but not the registered class. This is primarily -for performance reasons: when the trampoline class is not needed for anything -except virtual method dispatching, not initializing the trampoline class -improves performance by avoiding needing to do a run-time check to see if the -inheriting python instance has an overridden method. - -Sometimes, however, it is useful to always initialize a trampoline class as an -intermediate class that does more than just handle virtual method dispatching. -For example, such a class might perform extra class initialization, extra -destruction operations, and might define new members and methods to enable a -more python-like interface to a class. - -In order to tell pybind11 that it should *always* initialize the trampoline -class when creating new instances of a type, the class constructors should be -declared using ``py::init_alias()`` instead of the usual -``py::init()``. This forces construction via the trampoline class, -ensuring member initialization and (eventual) destruction. - -.. seealso:: - - See the file :file:`tests/test_virtual_functions.cpp` for complete examples - showing both normal and forced trampoline instantiation. - -Different method signatures ---------------------------- -The macro's introduced in :ref:`overriding_virtuals` cover most of the standard -use cases when exposing C++ classes to Python. Sometimes it is hard or unwieldy -to create a direct one-on-one mapping between the arguments and method return -type. - -An example would be when the C++ signature contains output arguments using -references (See also :ref:`faq_reference_arguments`). Another way of solving -this is to use the method body of the trampoline class to do conversions to the -input and return of the Python method. - -The main building block to do so is the :func:`get_override`, this function -allows retrieving a method implemented in Python from within the trampoline's -methods. Consider for example a C++ method which has the signature -``bool myMethod(int32_t& value)``, where the return indicates whether -something should be done with the ``value``. This can be made convenient on the -Python side by allowing the Python function to return ``None`` or an ``int``: - -.. code-block:: cpp - - bool MyClass::myMethod(int32_t& value) - { - pybind11::gil_scoped_acquire gil; // Acquire the GIL while in this scope. - // Try to look up the overridden method on the Python side. - pybind11::function override = pybind11::get_override(this, "myMethod"); - if (override) { // method is found - auto obj = override(value); // Call the Python function. - if (py::isinstance(obj)) { // check if it returned a Python integer type - value = obj.cast(); // Cast it and assign it to the value. - return true; // Return true; value should be used. - } else { - return false; // Python returned none, return false. - } - } - return false; // Alternatively return MyClass::myMethod(value); - } - - -.. _custom_constructors: - -Custom constructors -=================== - -The syntax for binding constructors was previously introduced, but it only -works when a constructor of the appropriate arguments actually exists on the -C++ side. To extend this to more general cases, pybind11 makes it possible -to bind factory functions as constructors. For example, suppose you have a -class like this: - -.. code-block:: cpp - - class Example { - private: - Example(int); // private constructor - public: - // Factory function: - static Example create(int a) { return Example(a); } - }; - - py::class_(m, "Example") - .def(py::init(&Example::create)); - -While it is possible to create a straightforward binding of the static -``create`` method, it may sometimes be preferable to expose it as a constructor -on the Python side. This can be accomplished by calling ``.def(py::init(...))`` -with the function reference returning the new instance passed as an argument. -It is also possible to use this approach to bind a function returning a new -instance by raw pointer or by the holder (e.g. ``std::unique_ptr``). - -The following example shows the different approaches: - -.. code-block:: cpp - - class Example { - private: - Example(int); // private constructor - public: - // Factory function - returned by value: - static Example create(int a) { return Example(a); } - - // These constructors are publicly callable: - Example(double); - Example(int, int); - Example(std::string); - }; - - py::class_(m, "Example") - // Bind the factory function as a constructor: - .def(py::init(&Example::create)) - // Bind a lambda function returning a pointer wrapped in a holder: - .def(py::init([](std::string arg) { - return std::unique_ptr(new Example(arg)); - })) - // Return a raw pointer: - .def(py::init([](int a, int b) { return new Example(a, b); })) - // You can mix the above with regular C++ constructor bindings as well: - .def(py::init()) - ; - -When the constructor is invoked from Python, pybind11 will call the factory -function and store the resulting C++ instance in the Python instance. - -When combining factory functions constructors with :ref:`virtual function -trampolines ` there are two approaches. The first is to -add a constructor to the alias class that takes a base value by -rvalue-reference. If such a constructor is available, it will be used to -construct an alias instance from the value returned by the factory function. -The second option is to provide two factory functions to ``py::init()``: the -first will be invoked when no alias class is required (i.e. when the class is -being used but not inherited from in Python), and the second will be invoked -when an alias is required. - -You can also specify a single factory function that always returns an alias -instance: this will result in behaviour similar to ``py::init_alias<...>()``, -as described in the :ref:`extended trampoline class documentation -`. - -The following example shows the different factory approaches for a class with -an alias: - -.. code-block:: cpp - - #include - class Example { - public: - // ... - virtual ~Example() = default; - }; - class PyExample : public Example { - public: - using Example::Example; - PyExample(Example &&base) : Example(std::move(base)) {} - }; - py::class_(m, "Example") - // Returns an Example pointer. If a PyExample is needed, the Example - // instance will be moved via the extra constructor in PyExample, above. - .def(py::init([]() { return new Example(); })) - // Two callbacks: - .def(py::init([]() { return new Example(); } /* no alias needed */, - []() { return new PyExample(); } /* alias needed */)) - // *Always* returns an alias instance (like py::init_alias<>()) - .def(py::init([]() { return new PyExample(); })) - ; - -Brace initialization --------------------- - -``pybind11::init<>`` internally uses C++11 brace initialization to call the -constructor of the target class. This means that it can be used to bind -*implicit* constructors as well: - -.. code-block:: cpp - - struct Aggregate { - int a; - std::string b; - }; - - py::class_(m, "Aggregate") - .def(py::init()); - -.. note:: - - Note that brace initialization preferentially invokes constructor overloads - taking a ``std::initializer_list``. In the rare event that this causes an - issue, you can work around it by using ``py::init(...)`` with a lambda - function that constructs the new object as desired. - -.. _classes_with_non_public_destructors: - -Non-public destructors -====================== - -If a class has a private or protected destructor (as might e.g. be the case in -a singleton pattern), a compile error will occur when creating bindings via -pybind11. The underlying issue is that the ``std::unique_ptr`` holder type that -is responsible for managing the lifetime of instances will reference the -destructor even if no deallocations ever take place. In order to expose classes -with private or protected destructors, it is possible to override the holder -type via a holder type argument to ``class_``. Pybind11 provides a helper class -``py::nodelete`` that disables any destructor invocations. In this case, it is -crucial that instances are deallocated on the C++ side to avoid memory leaks. - -.. code-block:: cpp - - /* ... definition ... */ - - class MyClass { - private: - ~MyClass() { } - }; - - /* ... binding code ... */ - - py::class_>(m, "MyClass") - .def(py::init<>()) - -.. _destructors_that_call_python: - -Destructors that call Python -============================ - -If a Python function is invoked from a C++ destructor, an exception may be thrown -of type :class:`error_already_set`. If this error is thrown out of a class destructor, -``std::terminate()`` will be called, terminating the process. Class destructors -must catch all exceptions of type :class:`error_already_set` to discard the Python -exception using :func:`error_already_set::discard_as_unraisable`. - -Every Python function should be treated as *possibly throwing*. When a Python generator -stops yielding items, Python will throw a ``StopIteration`` exception, which can pass -though C++ destructors if the generator's stack frame holds the last reference to C++ -objects. - -For more information, see :ref:`the documentation on exceptions `. - -.. code-block:: cpp - - class MyClass { - public: - ~MyClass() { - try { - py::print("Even printing is dangerous in a destructor"); - py::exec("raise ValueError('This is an unraisable exception')"); - } catch (py::error_already_set &e) { - // error_context should be information about where/why the occurred, - // e.g. use __func__ to get the name of the current function - e.discard_as_unraisable(__func__); - } - } - }; - -.. note:: - - pybind11 does not support C++ destructors marked ``noexcept(false)``. - -.. versionadded:: 2.6 - -.. _implicit_conversions: - -Implicit conversions -==================== - -Suppose that instances of two types ``A`` and ``B`` are used in a project, and -that an ``A`` can easily be converted into an instance of type ``B`` (examples of this -could be a fixed and an arbitrary precision number type). - -.. code-block:: cpp - - py::class_(m, "A") - /// ... members ... - - py::class_(m, "B") - .def(py::init()) - /// ... members ... - - m.def("func", - [](const B &) { /* .... */ } - ); - -To invoke the function ``func`` using a variable ``a`` containing an ``A`` -instance, we'd have to write ``func(B(a))`` in Python. On the other hand, C++ -will automatically apply an implicit type conversion, which makes it possible -to directly write ``func(a)``. - -In this situation (i.e. where ``B`` has a constructor that converts from -``A``), the following statement enables similar implicit conversions on the -Python side: - -.. code-block:: cpp - - py::implicitly_convertible(); - -.. note:: - - Implicit conversions from ``A`` to ``B`` only work when ``B`` is a custom - data type that is exposed to Python via pybind11. - - To prevent runaway recursion, implicit conversions are non-reentrant: an - implicit conversion invoked as part of another implicit conversion of the - same type (i.e. from ``A`` to ``B``) will fail. - -.. _static_properties: - -Static properties -================= - -The section on :ref:`properties` discussed the creation of instance properties -that are implemented in terms of C++ getters and setters. - -Static properties can also be created in a similar way to expose getters and -setters of static class attributes.

Suppose the class in question has the following signature: - -.. code-block:: cpp - - class Pickleable { - public: - Pickleable(const std::string &value) : m_value(value) { } - const std::string &value() const { return m_value; } - - void setExtra(int extra) { m_extra = extra; } - int extra() const { return m_extra; } - private: - std::string m_value; - int m_extra = 0; - }; - -Pickling support in Python is enabled by defining the ``__setstate__`` and -``__getstate__`` methods [#f3]_. For pybind11 classes, use ``py::pickle()`` -to bind these two functions: - -.. code-block:: cpp - - py::class_(m, "Pickleable") - .def(py::init()) - .def("value", &Pickleable::value) - .def("extra", &Pickleable::extra) - .def("setExtra", &Pickleable::setExtra) - .def(py::pickle( - [](const Pickleable &p) { // __getstate__ - /* Return a tuple that fully encodes the state of the object */ - return py::make_tuple(p.value(), p.extra()); - }, - [](py::tuple t) { // __setstate__ - if (t.size() != 2) - throw std::runtime_error("Invalid state!"); - - /* Create a new C++ instance */ - Pickleable p(t[0].cast()); - - /* Assign any additional state */ - p.setExtra(t[1].cast()); - - return p; - } - )); - -The ``__setstate__`` part of the ``py::pickle()`` definition follows the same -rules as the single-argument version of ``py::init()``. The return type can be -a value, pointer or holder type. See :ref:`custom_constructors` for details. - -An instance can now be pickled as follows: - -.. code-block:: python - - import pickle - - p = Pickleable("test_value") - p.setExtra(15) - data = pickle.dumps(p) - - -.. note:: - If given, the second argument to ``dumps`` must be 2 or larger - 0 and 1 are - not supported. Newer versions are also fine; for instance, specify ``-1`` to - always use the latest available version. Beware: failure to follow these - instructions will cause important pybind11 memory allocation routines to be - skipped during unpickling, which will likely lead to memory corruption - and/or segmentation faults. Python defaults to version 3 (Python 3-3.7) and - version 4 for Python 3.8+. - -.. seealso:: - - The file :file:`tests/test_pickling.cpp` contains a complete example - that demonstrates how to pickle and unpickle types using pybind11 in more - detail. - -.. [#f3] http://docs.python.org/3/library/pickle.html#pickling-class-instances - -Deepcopy support -================ - -Python normally uses references in assignments. Sometimes a real copy is needed -to prevent changing all copies. The ``copy`` module [#f5]_ provides these -capabilities. - -A class with pickle support is automatically also (deep)copy -compatible. However, performance can be improved by adding custom -``__copy__`` and ``__deepcopy__`` methods. - -For simple classes (deep)copy can be enabled by using the copy constructor, -which should look as follows: - -.. code-block:: cpp - - py::class_(m, "Copyable") - .def("__copy__", [](const Copyable &self) { - return Copyable(self); - }) - .def("__deepcopy__", [](const Copyable &self, py::dict) { - return Copyable(self); - }, "memo"_a); - -.. note:: - - Dynamic attributes will not be copied in this example. - -.. [#f5] https://docs.python.org/3/library/copy.html - -Multiple Inheritance -==================== - -pybind11 can create bindings for types that derive from multiple base types -(aka. *multiple inheritance*). To do so, specify all bases in the template -arguments of the ``class_`` declaration: - -.. code-block:: cpp - - py::class_(m, "MyType") - ... - -The base types can be specified in arbitrary order, and they can even be -interspersed with alias types and holder types (discussed earlier in this -document)---pybind11 will automatically find out which is which. The only -requirement is that the first template argument is the type to be declared. - -It is also permitted to inherit multiply from exported C++ classes in Python, -as well as inheriting from multiple Python and/or pybind11-exported classes. - -There is one caveat regarding the implementation of this feature: - -When only one base type is specified for a C++ type that actually has multiple -bases, pybind11 will assume that it does not participate in multiple -inheritance, which can lead to undefined behavior. In such cases, add the tag -``multiple_inheritance`` to the class constructor: - -.. code-block:: cpp - - py::class_(m, "MyType", py::multiple_inheritance()); - -The tag is redundant and does not need to be specified when multiple base types -are listed. - -.. _module_local: - -Module-local class bindings -=========================== - -When creating a binding for a class, pybind11 by default makes that binding -"global" across modules. What this means is that a type defined in one module -can be returned from any module resulting in the same Python type. For -example, this allows the following: - -.. code-block:: cpp - - // In the module1.cpp binding code for module1: - py::class_(m, "Pet") - .def(py::init()) - .def_readonly("name", &Pet::name); - -.. code-block:: cpp - - // In the module2.cpp binding code for module2: - m.def("create_pet", [](std::string name) { return new Pet(name); }); - -.. code-block:: pycon - - >>> from module1 import Pet - >>> from module2 import create_pet - >>> pet1 = Pet("Kitty") - >>> pet2 = create_pet("Doggy") - >>> pet2.name() - 'Doggy' - -When writing binding code for a library, this is usually desirable: this -allows, for example, splitting up a complex library into multiple Python -modules. - -In some cases, however, this can cause conflicts. For example, suppose two -unrelated modules make use of an external C++ library and each provide custom -bindings for one of that library's classes. This will result in an error when -a Python program attempts to import both modules (directly or indirectly) -because of conflicting definitions on the external type: - -.. code-block:: cpp - - // dogs.cpp - - // Binding for external library class: - py::class(m, "Pet") - .def("name", &pets::Pet::name); - - // Binding for local extension class: - py::class(m, "Dog") - .def(py::init()); - -.. code-block:: cpp - - // cats.cpp, in a completely separate project from the above dogs.cpp. - - // Binding for external library class: - py::class(m, "Pet") - .def("get_name", &pets::Pet::name); - - // Binding for local extending class: - py::class(m, "Cat") - .def(py::init()); - -.. code-block:: pycon - - >>> import cats - >>> import dogs - Traceback (most recent call last): - File "", line 1, in - ImportError: generic_type: type "Pet" is already registered! - -To get around this, you can tell pybind11 to keep the external class binding -localized to the module by passing the ``py::module_local()`` attribute into -the ``py::class_`` constructor: - -.. code-block:: cpp - - // Pet binding in dogs.cpp: - py::class(m, "Pet", py::module_local()) - .def("name", &pets::Pet::name); - -.. code-block:: cpp - - // Pet binding in cats.cpp: - py::class(m, "Pet", py::module_local()) - .def("get_name", &pets::Pet::name); - -This makes the Python-side ``dogs.Pet`` and ``cats.Pet`` into distinct classes, -avoiding the conflict and allowing both modules to be loaded. C++ code in the -``dogs`` module that casts or returns a ``Pet`` instance will result in a -``dogs.Pet`` Python instance, while C++ code in the ``cats`` module will result -in a ``cats.Pet`` Python instance. - -This does come with two caveats, however: First, external modules cannot return -or cast a ``Pet`` instance to Python (unless they also provide their own local -bindings). Second, from the Python point of view they are two distinct classes. - -Note that the locality only applies in the C++ -> Python direction. When -passing such a ``py::module_local`` type into a C++ function, the module-local -classes are still considered. This means that if the following function is -added to any module (including but not limited to the ``cats`` and ``dogs`` -modules above) it will be callable with either a ``dogs.Pet`` or ``cats.Pet`` -argument: - -.. code-block:: cpp - - m.def("pet_name", [](const pets::Pet &pet) { return pet.name(); }); - -For example, suppose the above function is added to each of ``cats.cpp``, -``dogs.cpp`` and ``frogs.cpp`` (where ``frogs.cpp`` is some other module that -does *not* bind ``Pets`` at all). - -.. code-block:: pycon - - >>> import cats, dogs, frogs # No error because of the added py::module_local() - >>> mycat, mydog = cats.Cat("Fluffy"), dogs.Dog("Rover") - >>> (cats.pet_name(mycat), dogs.pet_name(mydog)) - ('Fluffy', 'Rover') - >>> (cats.pet_name(mydog), dogs.pet_name(mycat), frogs.pet_name(mycat)) - ('Rover', 'Fluffy', 'Fluffy') - -It is possible to use ``py::module_local()`` registrations in one module even -if another module registers the same type globally: within the module with the -module-local definition, all C++ instances will be cast to the associated bound -Python type. In other modules any such values are converted to the global -Python type created elsewhere. - -.. note:: - - STL bindings (as provided via the optional :file:`pybind11/stl_bind.h` - header) apply ``py::module_local`` by default when the bound type might - conflict with other modules; see :ref:`stl_bind` for details. - -.. note:: - - The localization of the bound types is actually tied to the shared object - or binary generated by the compiler/linker. For typical modules created - with ``PYBIND11_MODULE()``, this distinction is not significant. It is - possible, however, when :ref:`embedding` to embed multiple modules in the - same binary (see :ref:`embedding_modules`). In such a case, the - localization will apply across all embedded modules within the same binary. - -.. seealso:: - - The file :file:`tests/test_local_bindings.cpp` contains additional examples - that demonstrate how ``py::module_local()`` works. - -Binding protected member functions -================================== - -It's normally not possible to expose ``protected`` member functions to Python: - -.. code-block:: cpp - - class A { - protected: - int foo() const { return 42; } - }; - - py::class_(m, "A") - .def("foo", &A::foo); // error: 'foo' is a protected member of 'A' - -On one hand, this is good because non-``public`` members aren't meant to be -accessed from the outside. But we may want to make use of ``protected`` -functions in derived Python classes. - -The following pattern makes this possible: - -.. code-block:: cpp - - class A { - protected: - int foo() const { return 42; } - }; - - class Publicist : public A { // helper type for exposing protected functions - public: - using A::foo; // inherited with different access modifier - }; - - py::class_(m, "A") // bind the primary class - .def("foo", &Publicist::foo); // expose protected methods via the publicist - -This works because ``&Publicist::foo`` is exactly the same function as -``&A::foo`` (same signature and address), just with a different access -modifier. The only purpose of the ``Publicist`` helper class is to make -the function name ``public``. - -If the intent is to expose ``protected`` ``virtual`` functions which can be -overridden in Python, the publicist pattern can be combined with the previously -described trampoline: - -.. code-block:: cpp - - class A { - public: - virtual ~A() = default; - - protected: - virtual int foo() const { return 42; } - }; - - class Trampoline : public A { - public: - int foo() const override { PYBIND11_OVERRIDE(int, A, foo, ); } - }; - - class Publicist : public A { - public: - using A::foo; - }; - - py::class_(m, "A") // <-- `Trampoline` here - .def("foo", &Publicist::foo); // <-- `Publicist` here, not `Trampoline`! - -Binding final classes -===================== - -Some classes may not be appropriate to inherit from. In C++11, classes can -use the ``final`` specifier to ensure that a class cannot be inherited from. -The ``py::is_final`` attribute can be used to ensure that Python classes -cannot inherit from a specified type. The underlying C++ type does not need -to be declared final. - -.. code-block:: cpp - - class IsFinal final {}; - - py::class_(m, "IsFinal", py::is_final()); - -When you try to inherit from such a class in Python, you will now get this -error: - -.. code-block:: pycon - - >>> class PyFinalChild(IsFinal): - ... pass - ... - TypeError: type 'IsFinal' is not an acceptable base type - -.. note:: This attribute is currently ignored on PyPy - -.. versionadded:: 2.6 - -Binding classes with template parameters -======================================== - -pybind11 can also wrap classes that have template parameters. Consider these classes: - -.. code-block:: cpp - - struct Cat {}; - struct Dog {}; - - template - struct Cage { - Cage(PetType& pet); - PetType& get(); - }; - -C++ templates may only be instantiated at compile time, so pybind11 can only -wrap instantiated templated classes. You cannot wrap a non-instantiated template: - -.. code-block:: cpp - - // BROKEN (this will not compile) - py::class_(m, "Cage"); - .def("get", &Cage::get); - -You must explicitly specify each template/type combination that you want to -wrap separately. - -.. code-block:: cpp - - // ok - py::class_>(m, "CatCage") - .def("get", &Cage::get); - - // ok - py::class_>(m, "DogCage") - .def("get", &Cage::get); - -If your class methods have template parameters you can wrap those as well, -but once again each instantiation must be explicitly specified: - -.. code-block:: cpp - - typename - struct MyClass { - template - T fn(V v); - }; - - py::class>(m, "MyClassT") - .def("fn", &MyClass::fn); - -Custom automatic downcasters -============================ - -As explained in :ref:`inheritance`, pybind11 comes with built-in -understanding of the dynamic type of polymorphic objects in C++; that -is, returning a Pet to Python produces a Python object that knows it's -wrapping a Dog, if Pet has virtual methods and pybind11 knows about -Dog and this Pet is in fact a Dog. Sometimes, you might want to -provide this automatic downcasting behavior when creating bindings for -a class hierarchy that does not use standard C++ polymorphism, such as -LLVM [#f4]_. As long as there's some way to determine at runtime -whether a downcast is safe, you can proceed by specializing the -``pybind11::polymorphic_type_hook`` template: - -.. code-block:: cpp - - enum class PetKind { Cat, Dog, Zebra }; - struct Pet { // Not polymorphic: has no virtual methods - const PetKind kind; - int age = 0; - protected: - Pet(PetKind _kind) : kind(_kind) {} - }; - struct Dog : Pet { - Dog() : Pet(PetKind::Dog) {} - std::string sound = "woof!"; - std::string bark() const { return sound; } - }; - - namespace PYBIND11_NAMESPACE { - template<> struct polymorphic_type_hook { - static const void *get(const Pet *src, const std::type_info*& type) { - // note that src may be nullptr - if (src && src->kind == PetKind::Dog) { - type = &typeid(Dog); - return static_cast(src); - } - return src; - } - }; - } // namespace PYBIND11_NAMESPACE - -When pybind11 wants to convert a C++ pointer of type ``Base*`` to a -Python object, it calls ``polymorphic_type_hook::get()`` to -determine if a downcast is possible. The ``get()`` function should use -whatever runtime information is available to determine if its ``src`` -parameter is in fact an instance of some class ``Derived`` that -inherits from ``Base``. If it finds such a ``Derived``, it sets ``type -= &typeid(Derived)`` and returns a pointer to the ``Derived`` object -that contains ``src``. Otherwise, it just returns ``src``, leaving -``type`` at its default value of nullptr. If you set ``type`` to a -type that pybind11 doesn't know about, no downcasting will occur, and -the original ``src`` pointer will be used with its static type -``Base*``. - -It is critical that the returned pointer and ``type`` argument of -``get()`` agree with each other: if ``type`` is set to something -non-null, the returned pointer must point to the start of an object -whose type is ``type``. If the hierarchy being exposed uses only -single inheritance, a simple ``return src;`` will achieve this just -fine, but in the general case, you must cast ``src`` to the -appropriate derived-class pointer (e.g. using -``static_cast(src)``) before allowing it to be returned as a -``void*``. - -.. [#f4] https://llvm.org/docs/HowToSetUpLLVMStyleRTTI.html - -.. note:: - - pybind11's standard support for downcasting objects whose types - have virtual methods is implemented using - ``polymorphic_type_hook`` too, using the standard C++ ability to - determine the most-derived type of a polymorphic object using - ``typeid()`` and to cast a base pointer to that most-derived type - (even if you don't know what it is) using ``dynamic_cast``. - -.. seealso:: - - The file :file:`tests/test_tagbased_polymorphic.cpp` contains a - more complete example, including a demonstration of how to provide - automatic downcasting for an entire class hierarchy without - writing one get() function for each class. - -Accessing the type object -========================= - -You can get the type object from a C++ class that has already been registered using: - -.. code-block:: cpp - - py::type T_py = py::type::of(); - -You can directly use ``py::type::of(ob)`` to get the type object from any python -object, just like ``type(ob)`` in Python. - -.. note:: - - Other types, like ``py::type::of()``, do not work, see :ref:`type-conversions`. - -.. versionadded:: 2.6 - -Custom type setup -================= - -For advanced use cases, such as enabling garbage collection support, you may -wish to directly manipulate the ``PyHeapTypeObject`` corresponding to a -``py::class_`` definition. - -You can do that using ``py::custom_type_setup``: - -.. code-block:: cpp - - struct OwnsPythonObjects { - py::object value = py::none(); - }; - py::class_ cls( - m, "OwnsPythonObjects", py::custom_type_setup([](PyHeapTypeObject *heap_type) { - auto *type = &heap_type->ht_type; - type->tp_flags |= Py_TPFLAGS_HAVE_GC; - type->tp_traverse = [](PyObject *self_base, visitproc visit, void *arg) { - auto &self = py::cast(py::handle(self_base)); - Py_VISIT(self.value.ptr()); - return 0; - }; - type->tp_clear = [](PyObject *self_base) { - auto &self = py::cast(py::handle(self_base)); - self.value = py::none(); - return 0; - }; - })); - cls.def(py::init<>()); - cls.def_readwrite("value", &OwnsPythonObjects::value); - -.. versionadded:: 2.8 diff --git a/oxpy/pybind11/docs/advanced/embedding.rst b/oxpy/pybind11/docs/advanced/embedding.rst deleted file mode 100644 index dd980d483..000000000 --- a/oxpy/pybind11/docs/advanced/embedding.rst +++ /dev/null @@ -1,262 +0,0 @@ -.. _embedding: - -Embedding the interpreter -######################### - -While pybind11 is mainly focused on extending Python using C++, it's also -possible to do the reverse: embed the Python interpreter into a C++ program. -All of the other documentation pages still apply here, so refer to them for -general pybind11 usage.

Call - policies indicate reference relationships that can involve both return values - and parameters of functions. - -.. note:: - - As an alternative to elaborate call policies and lifetime management logic, - consider using smart pointers (see the section on :ref:`smart_pointers` for - details). Smart pointers can tell whether an object is still referenced from - C++ or Python, which generally eliminates the kinds of inconsistencies that - can lead to crashes or undefined behavior. For functions returning smart - pointers, it is not necessary to specify a return value policy. - -.. _call_policies: - -Additional call policies -======================== - -In addition to the above return value policies, further *call policies* can be -specified to indicate dependencies between parameters or ensure a certain state -for the function call. - -Keep alive ----------- - -In general, this policy is required when the C++ object is any kind of container -and another object is being added to the container. ``keep_alive`` -indicates that the argument with index ``Patient`` should be kept alive at least -until the argument with index ``Nurse`` is freed by the garbage collector. Argument -indices start at one, while zero refers to the return value. For methods, index -``1`` refers to the implicit ``this`` pointer, while regular arguments begin at -index ``2``. Arbitrarily many call policies can be specified. When a ``Nurse`` -with value ``None`` is detected at runtime, the call policy does nothing. - -When the nurse is not a pybind11-registered type, the implementation internally -relies on the ability to create a *weak reference* to the nurse object. When -the nurse object is not a pybind11-registered type and does not support weak -references, an exception will be thrown. - -If you use an incorrect argument index, you will get a ``RuntimeError`` saying -``Could not activate keep_alive!``. You should review the indices you're using. - -Consider the following example: here, the binding code for a list append -operation ties the lifetime of the newly added element to the underlying -container: - -.. code-block:: cpp - - py::class_(m, "List") - .def("append", &List::append, py::keep_alive<1, 2>()); - -For consistency, the argument indexing is identical for constructors. Index -``1`` still refers to the implicit ``this`` pointer, i.e. the object which is -being constructed. Index ``0`` refers to the return type which is presumed to -be ``void`` when a constructor is viewed like a function. The following example -ties the lifetime of the constructor element to the constructed object: - -.. code-block:: cpp - - py::class_(m, "Nurse") - .def(py::init(), py::keep_alive<1, 2>()); - -.. note:: - - ``keep_alive`` is analogous to the ``with_custodian_and_ward`` (if Nurse, - Patient != 0) and ``with_custodian_and_ward_postcall`` (if Nurse/Patient == - 0) policies from Boost.Python. - -Call guard ----------- - -The ``call_guard`` policy allows any scope guard type ``T`` to be placed -around the function call. For example, this definition: - -.. code-block:: cpp - - m.def("foo", foo, py::call_guard()); - -is equivalent to the following pseudocode: - -.. code-block:: cpp - - m.def("foo", [](args...) { - T scope_guard; - return foo(args...); // forwarded arguments - }); - -The only requirement is that ``T`` is default-constructible, but otherwise any -scope guard will work. This is very useful in combination with ``gil_scoped_release``. -See :ref:`gil`. - -Multiple guards can also be specified as ``py::call_guard``. The -constructor order is left to right and destruction happens in reverse. - -.. seealso:: - - The file :file:`tests/test_call_policies.cpp` contains a complete example - that demonstrates using `keep_alive` and `call_guard` in more detail. - -.. _python_objects_as_args: - -Python objects as arguments -=========================== - -pybind11 exposes all major Python types using thin C++ wrapper classes. These -wrapper classes can also be used as parameters of functions in bindings, which -makes it possible to directly work with native Python types on the C++ side. -For instance, the following statement iterates over a Python ``dict``: - -.. code-block:: cpp - - void print_dict(const py::dict& dict) { - /* Easily interact with Python types */ - for (auto item : dict) - std::cout << "key=" << std::string(py::str(item.first)) << ", " - << "value=" << std::string(py::str(item.second)) << std::endl; - } - -It can be exported: - -.. code-block:: cpp - - m.def("print_dict", &print_dict); - -And used in Python as usual: - -.. code-block:: pycon - - >>> print_dict({"foo": 123, "bar": "hello"}) - key=foo, value=123 - key=bar, value=hello - -For more information on using Python objects in C++, see :doc:`/advanced/pycpp/index`. - -Accepting \*args and \*\*kwargs -=============================== - -Python provides a useful mechanism to define functions that accept arbitrary -numbers of arguments and keyword arguments: - -.. code-block:: python - - def generic(*args, **kwargs): - ... # do something with args and kwargs - -Such functions can also be created using pybind11: - -.. code-block:: cpp - - void generic(py::args args, const py::kwargs& kwargs) { - /// .. do something with args - if (kwargs) - /// .. do something with kwargs - } - - /// Binding code - m.def("generic", &generic); - -The class ``py::args`` derives from ``py::tuple`` and ``py::kwargs`` derives -from ``py::dict``. - -You may also use just one or the other, and may combine these with other -arguments. Note, however, that ``py::kwargs`` must always be the last argument -of the function, and ``py::args`` implies that any further arguments are -keyword-only (see :ref:`keyword_only_arguments`). - -Please refer to the other examples for details on how to iterate over these, -and on how to cast their entries into C++ objects. A demonstration is also -available in ``tests/test_kwargs_and_defaults.cpp``. - -.. note:: - - When combining \*args or \*\*kwargs with :ref:`keyword_args` you should - *not* include ``py::arg`` tags for the ``py::args`` and ``py::kwargs`` - arguments. - -Default arguments revisited -=========================== - -The section on :ref:`default_args` previously discussed basic usage of default -arguments using pybind11. One noteworthy aspect of their implementation is that -default arguments are converted to Python objects right at declaration time. -Consider the following example: - -.. code-block:: cpp - - py::class_("MyClass") - .def("myFunction", py::arg("arg") = SomeType(123)); - -In this case, pybind11 must already be set up to deal with values of the type -``SomeType`` (via a prior instantiation of ``py::class_``), or an -exception will be thrown. - -Another aspect worth highlighting is that the "preview" of the default argument -in the function signature is generated using the object's ``__repr__`` method. -If not available, the signature may not be very helpful, e.g.: - -.. code-block:: pycon - - FUNCTIONS - ... - | myFunction(...) - | Signature : (MyClass, arg : SomeType = ) -> NoneType - ... - -The first way of addressing this is by defining ``SomeType.__repr__``. -Alternatively, it is possible to specify the human-readable preview of the -default argument manually using the ``arg_v`` notation: - -.. code-block:: cpp - - py::class_("MyClass") - .def("myFunction", py::arg_v("arg", SomeType(123), "SomeType(123)")); - -Sometimes it may be necessary to pass a null pointer value as a default -argument. In this case, remember to cast it to the underlying type in question, -like so: - -.. code-block:: cpp - - py::class_("MyClass") - .def("myFunction", py::arg("arg") = static_cast(nullptr)); - -.. _keyword_only_arguments: - -Keyword-only arguments -====================== - -Python implements keyword-only arguments by specifying an unnamed ``*`` -argument in a function definition: - -.. code-block:: python - - def f(a, *, b): # a can be positional or via keyword; b must be via keyword - pass - - - f(a=1, b=2) # good - f(b=2, a=1) # good - f(1, b=2) # good - f(1, 2) # TypeError: f() takes 1 positional argument but 2 were given - -Pybind11 provides a ``py::kw_only`` object that allows you to implement -the same behaviour by specifying the object between positional and keyword-only -argument annotations when registering the function: - -.. code-block:: cpp - - m.def("f", [](int a, int b) { /* ... */ }, - py::arg("a"), py::kw_only(), py::arg("b")); - -.. versionadded:: 2.6 - -A ``py::args`` argument implies that any following arguments are keyword-only, -as if ``py::kw_only()`` had been specified in the same relative location of the -argument list as the ``py::args`` argument. The ``py::kw_only()`` may be -included to be explicit about this, but is not required. - -.. versionchanged:: 2.9 - This can now be combined with ``py::args``. Before, ``py::args`` could only - occur at the end of the argument list, or immediately before a ``py::kwargs`` - argument at the end. - - -Positional-only arguments -========================= - -Python 3.8 introduced a new positional-only argument syntax, using ``/`` in the -function definition (note that this has been a convention for CPython -positional arguments, such as in ``pow()``, since Python 2). You can -do the same thing in any version of Python using ``py::pos_only()``: - -.. code-block:: cpp - - m.def("f", [](int a, int b) { /* ... */ }, - py::arg("a"), py::pos_only(), py::arg("b")); - -You now cannot give argument ``a`` by keyword. This can be combined with -keyword-only arguments, as well. - -.. versionadded:: 2.6 - -.. _nonconverting_arguments: - -Non-converting arguments -======================== - -Certain argument types may support conversion from one type to another. Some -examples of conversions are: - -* :ref:`implicit_conversions` declared using ``py::implicitly_convertible()`` -* Calling a method accepting a double with an integer argument -* Calling a ``std::complex`` argument with a non-complex python type - (for example, with a float). (Requires the optional ``pybind11/complex.h`` - header). -* Calling a function taking an Eigen matrix reference with a numpy array of the - wrong type or of an incompatible data layout. (Requires the optional - ``pybind11/eigen.h`` header). - -This behaviour is sometimes undesirable: the binding code may prefer to raise -an error rather than convert the argument. This behaviour can be obtained -through ``py::arg`` by calling the ``.noconvert()`` method of the ``py::arg`` -object, such as: - -.. code-block:: cpp - - m.def("floats_only", [](double f) { return 0.5 * f; }, py::arg("f").noconvert()); - m.def("floats_preferred", [](double f) { return 0.5 * f; }, py::arg("f")); - -Attempting the call the second function (the one without ``.noconvert()``) with -an integer will succeed, but attempting to call the ``.noconvert()`` version -will fail with a ``TypeError``: - -.. code-block:: pycon - - >>> floats_preferred(4) - 2.0 - >>> floats_only(4) - Traceback (most recent call last): - File "", line 1, in - TypeError: floats_only(): incompatible function arguments. The following argument types are supported: - 1. (f: float) -> float - - Invoked with: 4 - -You may, of course, combine this with the :var:`_a` shorthand notation (see -:ref:`keyword_args`) and/or :ref:`default_args`. It is also permitted to omit -the argument name by using the ``py::arg()`` constructor without an argument -name, i.e. by specifying ``py::arg().noconvert()``. - -.. note:: - - When specifying ``py::arg`` options it is necessary to provide the same - number of options as the bound function has arguments. Thus if you want to - enable no-convert behaviour for just one of several arguments, you will - need to specify a ``py::arg()`` annotation for each argument with the - no-convert argument modified to ``py::arg().noconvert()``. - -.. _none_arguments: - -Allow/Prohibiting None arguments -================================ - -When a C++ type registered with :class:`py::class_` is passed as an argument to -a function taking the instance as pointer or shared holder (e.g. ``shared_ptr`` -or a custom, copyable holder as described in :ref:`smart_pointers`), pybind -allows ``None`` to be passed from Python which results in calling the C++ -function with ``nullptr`` (or an empty holder) for the argument. - -To explicitly enable or disable this behaviour, using the -``.none`` method of the :class:`py::arg` object: - -.. code-block:: cpp - - py::class_(m, "Dog").def(py::init<>()); - py::class_(m, "Cat").def(py::init<>()); - m.def("bark", [](Dog *dog) -> std::string { - if (dog) return "woof!"; /* Called with a Dog instance */ - else return "(no dog)"; /* Called with None, dog == nullptr */ - }, py::arg("dog").none(true)); - m.def("meow", [](Cat *cat) -> std::string { - // Can't be called with None argument - return "meow"; - }, py::arg("cat").none(false)); - -With the above, the Python call ``bark(None)`` will return the string ``"(no -dog)"``, while attempting to call ``meow(None)`` will raise a ``TypeError``: - -.. code-block:: pycon - - >>> from animals import Dog, Cat, bark, meow - >>> bark(Dog()) - 'woof!' - >>> meow(Cat()) - 'meow' - >>> bark(None) - '(no dog)' - >>> meow(None) - Traceback (most recent call last): - File "", line 1, in - TypeError: meow(): incompatible function arguments. The following argument types are supported: - 1. (cat: animals.Cat) -> str - - Invoked with: None - -The default behaviour when the tag is unspecified is to allow ``None``. - -.. note:: - - Even when ``.none(true)`` is specified for an argument, ``None`` will be converted to a - ``nullptr`` *only* for custom and :ref:`opaque ` types. Pointers to built-in types - (``double *``, ``int *``, ...) and STL types (``std::vector *``, ...; if ``pybind11/stl.h`` - is included) are copied when converted to C++ (see :doc:`/advanced/cast/overview`) and will - not allow ``None`` as argument. To pass optional argument of these copied types consider - using ``std::optional`` - -.. _overload_resolution: - -Overload resolution order -========================= - -When a function or method with multiple overloads is called from Python, -pybind11 determines which overload to call in two passes. The first pass -attempts to call each overload without allowing argument conversion (as if -every argument had been specified as ``py::arg().noconvert()`` as described -above). - -If no overload succeeds in the no-conversion first pass, a second pass is -attempted in which argument conversion is allowed (except where prohibited via -an explicit ``py::arg().noconvert()`` attribute in the function definition). - -If the second pass also fails a ``TypeError`` is raised. - -Within each pass, overloads are tried in the order they were registered with -pybind11. If the ``py::prepend()`` tag is added to the definition, a function -can be placed at the beginning of the overload sequence instead, allowing user -overloads to proceed built in functions. - -What this means in practice is that pybind11 will prefer any overload that does -not require conversion of arguments to an overload that does, but otherwise -prefers earlier-defined overloads to later-defined ones. - -.. note:: - - pybind11 does *not* further prioritize based on the number/pattern of - overloaded arguments. That is, pybind11 does not prioritize a function - requiring one conversion over one requiring three, but only prioritizes - overloads requiring no conversion at all to overloads that require - conversion of at least one argument. - -.. versionadded:: 2.6 - - The ``py::prepend()`` tag. - -Binding functions with template parameters -========================================== - -You can bind functions that have template parameters. Here's a function: - -.. code-block:: cpp - - template - void set(T t); - -C++ templates cannot be instantiated at runtime, so you cannot bind the -non-instantiated function: - -.. code-block:: cpp - - // BROKEN (this will not compile) - m.def("set", &set); - -You must bind each instantiated function template separately. You may bind -each instantiation with the same name, which will be treated the same as -an overloaded function: - -.. code-block:: cpp - - m.def("set", &set); - m.def("set", &set); - -Sometimes it's more clear to bind them with separate names, which is also -an option: - -.. code-block:: cpp - - m.def("setInt", &set); - m.def("setString", &set); diff --git a/oxpy/pybind11/docs/advanced/misc.rst b/oxpy/pybind11/docs/advanced/misc.rst deleted file mode 100644 index 805ec838f..000000000 --- a/oxpy/pybind11/docs/advanced/misc.rst +++ /dev/null @@ -1,400 +0,0 @@ -Miscellaneous -############# - -.. _macro_notes: - -General notes regarding convenience macros -========================================== - -pybind11 provides a few convenience macros such as -:func:`PYBIND11_DECLARE_HOLDER_TYPE` and ``PYBIND11_OVERRIDE_*``.

For example, if a Python callback is passed to C++ code via -``std::function``, when C++ code calls the function the built-in wrapper -will acquire the GIL before calling the Python callback. Similarly, the -``PYBIND11_OVERRIDE`` family of macros will acquire the GIL before calling -back into Python. - -When writing C++ code that is called from other C++ code, if that code accesses -Python state, it must explicitly acquire and release the GIL. - -The classes :class:`gil_scoped_release` and :class:`gil_scoped_acquire` can be -used to acquire and release the global interpreter lock in the body of a C++ -function call.

If you are -running into GIL related errors, we highly recommend you consult the -following checklist. - -- Do you have any global variables that are pybind11 objects or invoke - pybind11 functions in either their constructor or destructor? You are generally - not allowed to invoke any Python function in a global static context. We recommend - using lazy initialization and then intentionally leaking at the end of the program. - -- Do you have any pybind11 objects that are members of other C++ structures? One - commonly overlooked requirement is that pybind11 objects have to increase their reference count - whenever their copy constructor is called. Thus, you need to be holding the GIL to invoke - the copy constructor of any C++ class that has a pybind11 member. This can sometimes be very - tricky to track for complicated programs Think carefully when you make a pybind11 object - a member in another struct. - -- C++ destructors that invoke Python functions can be particularly troublesome as - destructors can sometimes get invoked in weird and unexpected circumstances as a result - of exceptions. - -- You should try running your code in a debug build. That will enable additional assertions - within pybind11 that will throw exceptions on certain GIL handling errors - (reference counting operations). - -Binding sequence data types, iterators, the slicing protocol, etc. -================================================================== - -Please refer to the supplemental example for details. - -.. seealso:: - - The file :file:`tests/test_sequences_and_iterators.cpp` contains a - complete example that shows how to bind a sequence data type, including - length queries (``__len__``), iterators (``__iter__``), the slicing - protocol and other kinds of useful operations. - - -Partitioning code over multiple extension modules -================================================= - -It's straightforward to split binding code over multiple extension modules, -while referencing types that are declared elsewhere. Everything "just" works -without any special precautions. One exception to this rule occurs when -extending a type declared in another extension module. Recall the basic example -from Section :ref:`inheritance`. - -.. code-block:: cpp - - py::class_ pet(m, "Pet"); - pet.def(py::init()) - .def_readwrite("name", &Pet::name); - - py::class_(m, "Dog", pet /* <- specify parent */) - .def(py::init()) - .def("bark", &Dog::bark); - -Suppose now that ``Pet`` bindings are defined in a module named ``basic``, -whereas the ``Dog`` bindings are defined somewhere else. The challenge is of -course that the variable ``pet`` is not available anymore though it is needed -to indicate the inheritance relationship to the constructor of ``class_``. -However, it can be acquired as follows: - -.. code-block:: cpp - - py::object pet = (py::object) py::module_::import("basic").attr("Pet"); - - py::class_(m, "Dog", pet) - .def(py::init()) - .def("bark", &Dog::bark); - -Alternatively, you can specify the base class as a template parameter option to -``class_``, which performs an automated lookup of the corresponding Python -type. Like the above code, however, this also requires invoking the ``import`` -function once to ensure that the pybind11 binding code of the module ``basic`` -has been executed: - -.. code-block:: cpp - - py::module_::import("basic"); - - py::class_(m, "Dog") - .def(py::init()) - .def("bark", &Dog::bark); - -Naturally, both methods will fail when there are cyclic dependencies. - -Note that pybind11 code compiled with hidden-by-default symbol visibility (e.g. -via the command line flag ``-fvisibility=hidden`` on GCC/Clang), which is -required for proper pybind11 functionality, can interfere with the ability to -access types defined in another extension module. Working around this requires -manually exporting types that are accessed by multiple extension modules; -pybind11 provides a macro to do just this: - -.. code-block:: cpp - - class PYBIND11_EXPORT Dog : public Animal { - ... - }; - -Note also that it is possible (although would rarely be required) to share arbitrary -C++ objects between extension modules at runtime. Internal library data is shared -between modules using capsule machinery [#f6]_ which can be also utilized for -storing, modifying and accessing user-defined data. Note that an extension module -will "see" other extensions' data if and only if they were built with the same -pybind11 version. Consider the following example: - -.. code-block:: cpp - - auto data = reinterpret_cast(py::get_shared_data("mydata")); - if (!data) - data = static_cast(py::set_shared_data("mydata", new MyData(42))); - -If the above snippet was used in several separately compiled extension modules, -the first one to be imported would create a ``MyData`` instance and associate -a ``"mydata"`` key with a pointer to it. Extensions that are imported later -would be then able to access the data behind the same pointer. - -.. [#f6] https://docs.python.org/3/extending/extending.html#using-capsules - -Module Destructors -================== - -pybind11 does not provide an explicit mechanism to invoke cleanup code at -module destruction time. In rare cases where such functionality is required, it -is possible to emulate it using Python capsules or weak references with a -destruction callback. - -.. code-block:: cpp - - auto cleanup_callback = []() { - // perform cleanup here -- this function is called with the GIL held - }; - - m.add_object("_cleanup", py::capsule(cleanup_callback)); - -This approach has the potential downside that instances of classes exposed -within the module may still be alive when the cleanup callback is invoked -(whether this is acceptable will generally depend on the application). - -Alternatively, the capsule may also be stashed within a type object, which -ensures that it not called before all instances of that type have been -collected: - -.. code-block:: cpp - - auto cleanup_callback = []() { /* ... */ }; - m.attr("BaseClass").attr("_cleanup") = py::capsule(cleanup_callback); - -Both approaches also expose a potentially dangerous ``_cleanup`` attribute in -Python, which may be undesirable from an API standpoint (a premature explicit -call from Python might lead to undefined behavior). Yet another approach that -avoids this issue involves weak reference with a cleanup callback: - -.. code-block:: cpp - - // Register a callback function that is invoked when the BaseClass object is collected - py::cpp_function cleanup_callback( - [](py::handle weakref) { - // perform cleanup here -- this function is called with the GIL held - - weakref.dec_ref(); // release weak reference - } - ); - - // Create a weak reference with a cleanup callback and initially leak it - (void) py::weakref(m.attr("BaseClass"), cleanup_callback).release(); - -.. note:: - - PyPy does not garbage collect objects when the interpreter exits. An alternative - approach (which also works on CPython) is to use the :py:mod:`atexit` module [#f7]_, - for example: - - .. code-block:: cpp - - auto atexit = py::module_::import("atexit"); - atexit.attr("register")(py::cpp_function([]() { - // perform cleanup here -- this function is called with the GIL held - })); - - .. [#f7] https://docs.python.org/3/library/atexit.html - - -Generating documentation using Sphinx -===================================== - -Sphinx [#f4]_ has the ability to inspect the signatures and documentation -strings in pybind11-based extension modules to automatically generate beautiful -documentation in a variety formats. The python_example repository [#f5]_ contains a -simple example repository which uses this approach. - -There are two potential gotchas when using this approach: first, make sure that -the resulting strings do not contain any :kbd:`TAB` characters, which break the -docstring parsing routines. You may want to use C++11 raw string literals, -which are convenient for multi-line comments. Conveniently, any excess -indentation will be automatically be removed by Sphinx. However, for this to -work, it is important that all lines are indented consistently, i.e.: - -.. code-block:: cpp - - // ok - m.def("foo", &foo, R"mydelimiter( - The foo function - - Parameters - ---------- - )mydelimiter"); - - // *not ok* - m.def("foo", &foo, R"mydelimiter(The foo function - - Parameters - ---------- - )mydelimiter"); - -By default, pybind11 automatically generates and prepends a signature to the docstring of a function -registered with ``module_::def()`` and ``class_::def()``. Sometimes this -behavior is not desirable, because you want to provide your own signature or remove -the docstring completely to exclude the function from the Sphinx documentation. -The class ``options`` allows you to selectively suppress auto-generated signatures: - -.. code-block:: cpp - - PYBIND11_MODULE(example, m) { - py::options options; - options.disable_function_signatures(); - - m.def("add", [](int a, int b) { return a + b; }, "A function which adds two numbers"); - } - -pybind11 also appends all members of an enum to the resulting enum docstring. -This default behavior can be disabled by using the ``disable_enum_members_docstring()`` -function of the ``options`` class. - -With ``disable_user_defined_docstrings()`` all user defined docstrings of -``module_::def()``, ``class_::def()`` and ``enum_()`` are disabled, but the -function signatures and enum members are included in the docstring, unless they -are disabled separately. - -Note that changes to the settings affect only function bindings created during the -lifetime of the ``options`` instance. When it goes out of scope at the end of the module's init function, -the default settings are restored to prevent unwanted side effects. - -.. [#f4] http://www.sphinx-doc.org -..

[#f2] http://docs.python.org/3/c-api/buffer.html - -Arrays -====== - -By exchanging ``py::buffer`` with ``py::array`` in the above snippet, we can -restrict the function so that it only accepts NumPy arrays (rather than any -type of Python object satisfying the buffer protocol). - -In many situations, we want to define a function which only accepts a NumPy -array of a certain data type. This is possible via the ``py::array_t`` -template. For instance, the following function requires the argument to be a -NumPy array containing double precision values. - -.. code-block:: cpp - - void f(py::array_t array); - -When it is invoked with a different type (e.g. an integer or a list of -integers), the binding code will attempt to cast the input into a NumPy array -of the requested type. This feature requires the :file:`pybind11/numpy.h` -header to be included. Note that :file:`pybind11/numpy.h` does not depend on -the NumPy headers, and thus can be used without declaring a build-time -dependency on NumPy; NumPy>=1.7.0 is a runtime dependency. - -Data in NumPy arrays is not guaranteed to packed in a dense manner; -furthermore, entries can be separated by arbitrary column and row strides. -Sometimes, it can be useful to require a function to only accept dense arrays -using either the C (row-major) or Fortran (column-major) ordering. This can be -accomplished via a second template argument with values ``py::array::c_style`` -or ``py::array::f_style``. - -.. code-block:: cpp - - void f(py::array_t array); - -The ``py::array::forcecast`` argument is the default value of the second -template parameter, and it ensures that non-conforming arguments are converted -into an array satisfying the specified requirements instead of trying the next -function overload. - -There are several methods on arrays; the methods listed below under references -work, as well as the following functions based on the NumPy API: - -- ``.dtype()`` returns the type of the contained values. - -- ``.strides()`` returns a pointer to the strides of the array (optionally pass - an integer axis to get a number). - -- ``.flags()`` returns the flag settings. ``.writable()`` and ``.owndata()`` - are directly available. - -- ``.offset_at()`` returns the offset (optionally pass indices). - -- ``.squeeze()`` returns a view with length-1 axes removed. - -- ``.view(dtype)`` returns a view of the array with a different dtype. - -- ``.reshape({i, j, ...})`` returns a view of the array with a different shape. - ``.resize({...})`` is also available. - -- ``.index_at(i, j, ...)`` gets the count from the beginning to a given index. - - -There are also several methods for getting references (described below). - -Structured types -================ - -In order for ``py::array_t`` to work with structured (record) types, we first -need to register the memory layout of the type. This can be done via -``PYBIND11_NUMPY_DTYPE`` macro, called in the plugin definition code, which -expects the type followed by field names: - -.. code-block:: cpp - - struct A { - int x; - double y; - }; - - struct B { - int z; - A a; - }; - - // ... - PYBIND11_MODULE(test, m) { - // ... - - PYBIND11_NUMPY_DTYPE(A, x, y); - PYBIND11_NUMPY_DTYPE(B, z, a); - /* now both A and B can be used as template arguments to py::array_t */ - } - -The structure should consist of fundamental arithmetic types, ``std::complex``, -previously registered substructures, and arrays of any of the above. Both C++ -arrays and ``std::array`` are supported. While there is a static assertion to -prevent many types of unsupported structures, it is still the user's -responsibility to use only "plain" structures that can be safely manipulated as -raw memory without violating invariants. - -Vectorizing functions -===================== - -Suppose we want to bind a function with the following signature to Python so -that it can process arbitrary NumPy array arguments (vectors, matrices, general -N-D arrays) in addition to its normal arguments: - -.. code-block:: cpp - - double my_func(int x, float y, double z); - -After including the ``pybind11/numpy.h`` header, this is extremely simple: - -.. code-block:: cpp - - m.def("vectorized_func", py::vectorize(my_func)); - -Invoking the function like below causes 4 calls to be made to ``my_func`` with -each of the array elements. The significant advantage of this compared to -solutions like ``numpy.vectorize()`` is that the loop over the elements runs -entirely on the C++ side and can be crunched down into a tight, optimized loop -by the compiler. The result is returned as a NumPy array of type -``numpy.dtype.float64``. - -.. code-block:: pycon - - >>> x = np.array([[1, 3], [5, 7]]) - >>> y = np.array([[2, 4], [6, 8]]) - >>> z = 3 - >>> result = vectorized_func(x, y, z) - -The scalar argument ``z`` is transparently replicated 4 times. The input -arrays ``x`` and ``y`` are automatically converted into the right types (they -are of type ``numpy.dtype.int64`` but need to be ``numpy.dtype.int32`` and -``numpy.dtype.float32``, respectively). - -.. note:: - - Only arithmetic, complex, and POD types passed by value or by ``const &`` - reference are vectorized; all other arguments are passed through as-is. - Functions taking rvalue reference arguments cannot be vectorized. - -In cases where the computation is too complicated to be reduced to -``vectorize``, it will be necessary to create and access the buffer contents -manually. The following snippet contains a complete example that shows how this -works (the code is somewhat contrived, since it could have been done more -simply using ``vectorize``). - -.. code-block:: cpp - - #include - #include - - namespace py = pybind11; - - py::array_t add_arrays(py::array_t input1, py::array_t input2) { - py::buffer_info buf1 = input1.request(), buf2 = input2.request(); - - if (buf1.ndim != 1 || buf2.ndim != 1) - throw std::runtime_error("Number of dimensions must be one"); - - if (buf1.size != buf2.size) - throw std::runtime_error("Input shapes must match"); - - /* No pointer is passed, so NumPy will allocate the buffer */ - auto result = py::array_t(buf1.size); - - py::buffer_info buf3 = result.request(); - - double *ptr1 = static_cast(buf1.ptr); - double *ptr2 = static_cast(buf2.ptr); - double *ptr3 = static_cast(buf3.ptr); - - for (size_t idx = 0; idx < buf1.shape[0]; idx++) - ptr3[idx] = ptr1[idx] + ptr2[idx]; - - return result; - } - - PYBIND11_MODULE(test, m) { - m.def("add_arrays", &add_arrays, "Add two NumPy arrays"); - } - -.. seealso:: - - The file :file:`tests/test_numpy_vectorize.cpp` contains a complete - example that demonstrates using :func:`vectorize` in more detail. - -Direct access -============= - -For performance reasons, particularly when dealing with very large arrays, it -is often desirable to directly access array elements without internal checking -of dimensions and bounds on every access when indices are known to be already -valid. To avoid such checks, the ``array`` class and ``array_t`` template -class offer an unchecked proxy object that can be used for this unchecked -access through the ``unchecked`` and ``mutable_unchecked`` methods, -where ``N`` gives the required dimensionality of the array: - -.. code-block:: cpp - - m.def("sum_3d", [](py::array_t x) { - auto r = x.unchecked<3>(); // x must have ndim = 3; can be non-writeable - double sum = 0; - for (py::ssize_t i = 0; i < r.shape(0); i++) - for (py::ssize_t j = 0; j < r.shape(1); j++) - for (py::ssize_t k = 0; k < r.shape(2); k++) - sum += r(i, j, k); - return sum; - }); - m.def("increment_3d", [](py::array_t x) { - auto r = x.mutable_unchecked<3>(); // Will throw if ndim != 3 or flags.writeable is false - for (py::ssize_t i = 0; i < r.shape(0); i++) - for (py::ssize_t j = 0; j < r.shape(1); j++) - for (py::ssize_t k = 0; k < r.shape(2); k++) - r(i, j, k) += 1.0; - }, py::arg().noconvert()); - -To obtain the proxy from an ``array`` object, you must specify both the data -type and number of dimensions as template arguments, such as ``auto r = -myarray.mutable_unchecked()``. - -If the number of dimensions is not known at compile time, you can omit the -dimensions template parameter (i.e. calling ``arr_t.unchecked()`` or -``arr.unchecked()``. This will give you a proxy object that works in the -same way, but results in less optimizable code and thus a small efficiency -loss in tight loops. - -Note that the returned proxy object directly references the array's data, and -only reads its shape, strides, and writeable flag when constructed. You must -take care to ensure that the referenced array is not destroyed or reshaped for -the duration of the returned object, typically by limiting the scope of the -returned instance. - -The returned proxy object supports some of the same methods as ``py::array`` so -that it can be used as a drop-in replacement for some existing, index-checked -uses of ``py::array``: - -- ``.ndim()`` returns the number of dimensions - -- ``.data(1, 2, ...)`` and ``r.mutable_data(1, 2, ...)``` returns a pointer to - the ``const T`` or ``T`` data, respectively, at the given indices. The - latter is only available to proxies obtained via ``a.mutable_unchecked()``. - -- ``.itemsize()`` returns the size of an item in bytes, i.e. ``sizeof(T)``. - -- ``.ndim()`` returns the number of dimensions. - -- ``.shape(n)`` returns the size of dimension ``n`` - -- ``.size()`` returns the total number of elements (i.e. the product of the shapes). - -- ``.nbytes()`` returns the number of bytes used by the referenced elements - (i.e. ``itemsize()`` times ``size()``). - -.. seealso:: - - The file :file:`tests/test_numpy_array.cpp` contains additional examples - demonstrating the use of this feature. - -Ellipsis -======== - -Python provides a convenient ``...`` ellipsis notation that is often used to -slice multidimensional arrays.

Previously - ``py::str`` could also hold ``bytes``, which is probably surprising, was - never documented, and can mask bugs (e.g. accidental use of ``py::str`` - instead of ``py::bytes``). - `#2409 `_ - -* Add a safety guard to ensure that the Python GIL is held when C++ calls back - into Python via ``object_api<>::operator()`` (e.g. ``py::function`` - ``__call__``). (This feature is available for Python 3.6+ only.) - `#2919 `_ - -* Catch a missing ``self`` argument in calls to ``__init__()``. - `#2914 `_ - -* Use ``std::string_view`` if available to avoid a copy when passing an object - to a ``std::ostream``. - `#3042 `_ - -* An important warning about thread safety was added to the ``iostream.h`` - documentation; attempts to make ``py::scoped_ostream_redirect`` thread safe - have been removed, as it was only partially effective. - `#2995 `_ - - -Fixes: - -* Performance: avoid unnecessary strlen calls. - `#3058 `_ - -* Fix auto-generated documentation string when using ``const T`` in - ``pyarray_t``. - `#3020 `_ - -* Unify error messages thrown by ``simple_collector``/``unpacking_collector``. - `#3013 `_ - -* ``pybind11::builtin_exception`` is now explicitly exported, which means the - types included/defined in different modules are identical, and exceptions - raised in different modules can be caught correctly. The documentation was - updated to explain that custom exceptions that are used across module - boundaries need to be explicitly exported as well. - `#2999 `_ - -* Fixed exception when printing UTF-8 to a ``scoped_ostream_redirect``. - `#2982 `_ - -* Pickle support enhancement: ``setstate`` implementation will attempt to - ``setattr`` ``__dict__`` only if the unpickled ``dict`` object is not empty, - to not force use of ``py::dynamic_attr()`` unnecessarily. - `#2972 `_ - -* Allow negative timedelta values to roundtrip. - `#2870 `_ - -* Fix unchecked errors could potentially swallow signals/other exceptions. - `#2863 `_ - -* Add null pointer check with ``std::localtime``. -

`#2657 `_ - -Fixed or improved behavior in a few special cases: - -* Fix bug where the constructor of ``object`` subclasses would not throw on - being passed a Python object of the wrong type. - `#2701 `_ - -* The ``type_caster`` for integers does not convert Python objects with - ``__int__`` anymore with ``noconvert`` or during the first round of trying - overloads. - `#2698 `_ - -* When casting to a C++ integer, ``__index__`` is always called and not - considered as conversion, consistent with Python 3.8+. - `#2801 `_ - -Build improvements: - -* Setup helpers: ``extra_compile_args`` and ``extra_link_args`` automatically set by - Pybind11Extension are now prepended, which allows them to be overridden - by user-set ``extra_compile_args`` and ``extra_link_args``. - `#2808 `_ - -* Setup helpers: Don't trigger unused parameter warning. - `#2735 `_ - -* CMake: Support running with ``--warn-uninitialized`` active. -

`#2716 `_ - - -Bug fixes: - -* Fixed segfault in multithreaded environments when using - ``scoped_ostream_redirect``. - `#2675 `_ - -* Leave docstring unset when all docstring-related options are disabled, rather - than set an empty string. - `#2745 `_ - -* The module key in builtins that pybind11 uses to store its internals changed - from std::string to a python str type (more natural on Python 2, no change on - Python 3). - `#2814 `_ - -* Fixed assertion error related to unhandled (later overwritten) exception in - CPython 3.8 and 3.9 debug builds. - `#2685 `_ - -* Fix ``py::gil_scoped_acquire`` assert with CPython 3.9 debug build. - `#2683 `_ - -* Fix issue with a test failing on pytest 6.2. - `#2741 `_ - -Warning fixes: - -* Fix warning modifying constructor parameter 'flag' that shadows a field of - 'set_flag' ``[-Wshadow-field-in-constructor-modified]``. - `#2780 `_ - -* Suppressed some deprecation warnings about old-style - ``__init__``/``__setstate__`` in the tests. - `#2759 `_ - -Valgrind work: - -* Fix invalid access when calling a pybind11 ``__init__`` on a non-pybind11 -

as ``"__builtins__"`` to their ``globals`` argument, better matching ``exec`` - and ``eval`` in pure Python. - `#2616 `_ - -* ``setup_helpers`` will no longer set a minimum macOS version higher than the - current version. - `#2622 `_ - -* Allow deleting static properties. - `#2629 `_ - -* Seal a leak in ``def_buffer``, cleaning up the ``capture`` object after the - ``class_`` object goes out of scope. - `#2634 `_ - -* ``pybind11_INCLUDE_DIRS`` was incorrect, potentially causing a regression if - it was expected to include ``PYTHON_INCLUDE_DIRS`` (please use targets - instead). - `#2636 `_ - -* Added parameter names to the ``py::enum_`` constructor and methods, avoiding - ``arg0`` in the generated docstrings. - `#2637 `_ - -* Added ``needs_recompile`` optional function to the ``ParallelCompiler`` - helper, to allow a recompile to be skipped based on a user-defined function. -

`#2372 `_ - -* ``py::hash`` is now public. - `#2217 `_ - -* ``py::class_`` is now supported. Note that writing to one data - member of the union and reading another (type punning) is UB in C++. Thus - pybind11-bound enums should never be used for such conversions. - `#2320 `_. - -* Classes now check local scope when registering members, allowing a subclass - to have a member with the same name as a parent (such as an enum). - `#2335 `_ - -Code correctness features: - -* Error now thrown when ``__init__`` is forgotten on subclasses. - `#2152 `_ - -* Throw error if conversion to a pybind11 type if the Python object isn't a - valid instance of that type, such as ``py::bytes(o)`` when ``py::object o`` - isn't a bytes instance. - `#2349 `_ - -* Throw if conversion to ``str`` fails. - `#2477 `_ - - -API changes: - -* ``py::module`` was renamed ``py::module_`` to avoid issues with C++20 when - used unqualified, but an alias ``py::module`` is provided for backward - compatibility. - `#2489 `_ - -* Public constructors for ``py::module_`` have been deprecated; please use - ``pybind11::module_::create_extension_module`` if you were using the public - constructor (fairly rare after ``PYBIND11_MODULE`` was introduced). - `#2552 `_ - -* ``PYBIND11_OVERLOAD*`` macros and ``get_overload`` function replaced by - correctly-named ``PYBIND11_OVERRIDE*`` and ``get_override``, fixing - inconsistencies in the presence of a closing ``;`` in these macros. - ``get_type_overload`` is deprecated. - `#2325 `_ - -Packaging / building improvements: - -* The Python package was reworked to be more powerful and useful. - `#2433 `_ - - * :ref:`build-setuptools` is easier thanks to a new - ``pybind11.setup_helpers`` module, which provides utilities to use - setuptools with pybind11. It can be used via PEP 518, ``setup_requires``, - or by directly importing or copying ``setup_helpers.py`` into your project. - - * CMake configuration files are now included in the Python package. Use - ``pybind11.get_cmake_dir()`` or ``python -m pybind11 --cmakedir`` to get - the directory with the CMake configuration files, or include the - site-packages location in your ``CMAKE_MODULE_PATH``. Or you can use the - new ``pybind11[global]`` extra when you install ``pybind11``, which - installs the CMake files and headers into your base environment in the - standard location. - - * ``pybind11-config`` is another way to write ``python -m pybind11`` if you - have your PATH set up. - - * Added external typing support to the helper module, code from - ``import pybind11`` can now be type checked. - `#2588 `_ - -* Minimum CMake required increased to 3.4. - `#2338 `_ and - `#2370 `_ - - * Full integration with CMake's C++ standard system and compile features - replaces ``PYBIND11_CPP_STANDARD``. - - * Generated config file is now portable to different Python/compiler/CMake - versions. - - * Virtual environments prioritized if ``PYTHON_EXECUTABLE`` is not set - (``venv``, ``virtualenv``, and ``conda``) (similar to the new FindPython - mode). - - * Other CMake features now natively supported, like - ``CMAKE_INTERPROCEDURAL_OPTIMIZATION``, ``set(CMAKE_CXX_VISIBILITY_PRESET - hidden)``. - - * ``CUDA`` as a language is now supported. - - * Helper functions ``pybind11_strip``, ``pybind11_extension``, - ``pybind11_find_import`` added, see :doc:`cmake/index`. - - * Optional :ref:`find-python-mode` and :ref:`nopython-mode` with CMake. - `#2370 `_ - -* Uninstall target added. - `#2265 `_ and - `#2346 `_ - -* ``pybind11_add_module()`` now accepts an optional ``OPT_SIZE`` flag that - switches the binding target to size-based optimization if the global build - type can not always be fixed to ``MinSizeRel`` (except in debug mode, where - optimizations remain disabled). ``MinSizeRel`` or this flag reduces binary - size quite substantially (~25% on some platforms). - `#2463 `_ - -Smaller or developer focused features and fixes: - -* Moved ``mkdoc.py`` to a new repo, `pybind11-mkdoc`_. There are no longer - submodules in the main repo. - -* ``py::memoryview`` segfault fix and update, with new - ``py::memoryview::from_memory`` in Python 3, and documentation. - `#2223 `_ - -* Fix for ``buffer_info`` on Python 2. - `#2503 `_ - -* If ``__eq__`` defined but not ``__hash__``, ``__hash__`` is now set to - ``None``. - `#2291 `_ - -* ``py::ellipsis`` now also works on Python 2. - `#2360 `_ - -* Pointer to ``std::tuple`` & ``std::pair`` supported in cast. - `#2334 `_ - -* Small fixes in NumPy support. ``py::array`` now uses ``py::ssize_t`` as first - argument type. - `#2293 `_ - -* Added missing signature for ``py::array``. - `#2363 `_ - -* ``unchecked_mutable_reference`` has access to operator ``()`` and ``[]`` when - const. - `#2514 `_ - -* ``py::vectorize`` is now supported on functions that return void. - `#1969 `_ - -* ``py::capsule`` supports ``get_pointer`` and ``set_pointer``. - `#1131 `_ - -* Fix crash when different instances share the same pointer of the same type. - `#2252 `_ - -* Fix for ``py::len`` not clearing Python's error state when it fails and throws. - `#2575 `_ - -* Bugfixes related to more extensive testing, new GitHub Actions CI. - `#2321 `_ - -* Bug in timezone issue in Eastern hemisphere midnight fixed. - `#2438 `_ - -* ``std::chrono::time_point`` now works when the resolution is not the same as - the system. - `#2481 `_ - -* Bug fixed where ``py::array_t`` could accept arrays that did not match the - requested ordering. - `#2484 `_ - -* Avoid a segfault on some compilers when types are removed in Python. - `#2564 `_ - -* ``py::arg::none()`` is now also respected when passing keyword arguments. - `#2611 `_ - -* PyPy fixes, PyPy 7.3.x now supported, including PyPy3.

See the - :doc:`documentation page ` for a - full overview of the new features. - `#774 `_, - `#889 `_, - `#892 `_, - `#920 `_. - - .. code-block:: cpp - - #include - namespace py = pybind11; - - int main() { - py::scoped_interpreter guard{}; // start the interpreter and keep it alive - - py::print("Hello, World!"); // use the Python API - } - -* Support for inheriting from multiple C++ bases in Python. - `#693 `_. - - .. code-block:: python - - from cpp_module import CppBase1, CppBase2 - - - class PyDerived(CppBase1, CppBase2): - def __init__(self): - CppBase1.__init__(self) # C++ bases must be initialized explicitly - CppBase2.__init__(self) - -* ``PYBIND11_MODULE`` is now the preferred way to create module entry points. - ``PYBIND11_PLUGIN`` is deprecated. See :ref:`macros` for details. - `#879 `_. - - .. code-block:: cpp - - // new - PYBIND11_MODULE(example, m) { - m.def("add", [](int a, int b) { return a + b; }); - } - - // old - PYBIND11_PLUGIN(example) { - py::module m("example"); - m.def("add", [](int a, int b) { return a + b; }); - return m.ptr(); - } - -* pybind11's headers and build system now more strictly enforce hidden symbol - visibility for extension modules. This should be seamless for most users, - but see the :doc:`upgrade` if you use a custom build system. - `#995 `_. - -* Support for ``py::module_local`` types which allow multiple modules to - export the same C++ types without conflicts. This is useful for opaque - types like ``std::vector``. ``py::bind_vector`` and ``py::bind_map`` - now default to ``py::module_local`` if their elements are builtins or - local types. See :ref:`module_local` for details. - `#949 `_, - `#981 `_, - `#995 `_, - `#997 `_. - -* Custom constructors can now be added very easily using lambdas or factory - functions which return a class instance by value, pointer or holder. This - supersedes the old placement-new ``__init__`` technique. - See :ref:`custom_constructors` for details. - `#805 `_, - `#1014 `_. - - .. code-block:: cpp - - struct Example { - Example(std::string); - }; - - py::class_(m, "Example") - .def(py::init()) // existing constructor - .def(py::init([](int n) { // custom constructor - return std::make_unique(std::to_string(n)); - })); - -* Similarly to custom constructors, pickling support functions are now bound - using the ``py::pickle()`` adaptor which improves type safety. See the - :doc:`upgrade` and :ref:`pickling` for details. - `#1038 `_. - -* Builtin support for converting C++17 standard library types and general - conversion improvements: - - 1. C++17 ``std::variant`` is supported right out of the box. C++11/14 - equivalents (e.g. ``boost::variant``) can also be added with a simple - user-defined specialization. See :ref:`cpp17_container_casters` for details. - `#811 `_, - `#845 `_, - `#989 `_. - - 2. Out-of-the-box support for C++17 ``std::string_view``. - `#906 `_. - - 3. Improved compatibility of the builtin ``optional`` converter. - `#874 `_. - - 4. The ``bool`` converter now accepts ``numpy.bool_`` and types which - define ``__bool__`` (Python 3.x) or ``__nonzero__`` (Python 2.7). - `#925 `_. - - 5. C++-to-Python casters are now more efficient and move elements out - of rvalue containers whenever possible. - `#851 `_, - `#936 `_, - `#938 `_. - - 6. Fixed ``bytes`` to ``std::string/char*`` conversion on Python 3. - `#817 `_. - - 7. Fixed lifetime of temporary C++ objects created in Python-to-C++ conversions. - `#924 `_. - -* Scope guard call policy for RAII types, e.g. ``py::call_guard()``, - ``py::call_guard()``. See :ref:`call_policies` for details. - `#740 `_. - -* Utility for redirecting C++ streams to Python (e.g. ``std::cout`` -> - ``sys.stdout``). Scope guard ``py::scoped_ostream_redirect`` in C++ and - a context manager in Python. See :ref:`ostream_redirect`. - `#1009 `_. - -* Improved handling of types and exceptions across module boundaries. - `#915 `_, - `#951 `_, - `#995 `_. - -* Fixed destruction order of ``py::keep_alive`` nurse/patient objects - in reference cycles. - `#856 `_. - -* NumPy and buffer protocol related improvements: - - 1. Support for negative strides in Python buffer objects/numpy arrays. This - required changing integers from unsigned to signed for the related C++ APIs. - Note: If you have compiler warnings enabled, you may notice some new conversion - warnings after upgrading. These can be resolved with ``static_cast``. - `#782 `_. - - 2. Support ``std::complex`` and arrays inside ``PYBIND11_NUMPY_DTYPE``. - `#831 `_, - `#832 `_. - - 3. Support for constructing ``py::buffer_info`` and ``py::arrays`` using - arbitrary containers or iterators instead of requiring a ``std::vector``. - `#788 `_, - `#822 `_, - `#860 `_. - - 4. Explicitly check numpy version and require >= 1.7.0. - `#819 `_. - -* Support for allowing/prohibiting ``None`` for specific arguments and improved - ``None`` overload resolution order. See :ref:`none_arguments` for details. - `#843 `_. - `#859 `_. - -* Added ``py::exec()`` as a shortcut for ``py::eval()`` - and support for C++11 raw string literals as input. See :ref:`eval`. - `#766 `_, - `#827 `_. - -* ``py::vectorize()`` ignores non-vectorizable arguments and supports - member functions. - `#762 `_. - -* Support for bound methods as callbacks (``pybind11/functional.h``). - `#815 `_. - -* Allow aliasing pybind11 methods: ``cls.attr("foo") = cls.attr("bar")``. - `#802 `_. - -* Don't allow mixed static/non-static overloads. - `#804 `_. - -* Fixed overriding static properties in derived classes. - `#784 `_. - -* Added support for write only properties. - `#1144 `_. - -* Improved deduction of member functions of a derived class when its bases - aren't registered with pybind11. - `#855 `_. - - .. code-block:: cpp - - struct Base { - int foo() { return 42; } - } - - struct Derived : Base {} - - // Now works, but previously required also binding `Base` - py::class_(m, "Derived") - .def("foo", &Derived::foo); // function is actually from `Base` - -* The implementation of ``py::init<>`` now uses C++11 brace initialization - syntax to construct instances, which permits binding implicit constructors of - aggregate types. `#1015 `_. - - .. code-block:: cpp - - struct Aggregate { - int a; - std::string b; - }; - - py::class_(m, "Aggregate") - .def(py::init()); - -* Fixed issues with multiple inheritance with offset base/derived pointers. - `#812 `_, - `#866 `_, - `#960 `_. - -* Fixed reference leak of type objects. - `#1030 `_. - -* Improved support for the ``/std:c++14`` and ``/std:c++latest`` modes - on MSVC 2017. - `#841 `_, - `#999 `_. - -* Fixed detection of private operator new on MSVC. - `#893 `_, - `#918 `_. - -* Intel C++ compiler compatibility fixes. - `#937 `_. - -* Fixed implicit conversion of ``py::enum_`` to integer types on Python 2.7. - `#821 `_. - -* Added ``py::hash`` to fetch the hash value of Python objects, and - ``.def(hash(py::self))`` to provide the C++ ``std::hash`` as the Python - ``__hash__`` method. - `#1034 `_. - -* Fixed ``__truediv__`` on Python 2 and ``__itruediv__`` on Python 3. - `#867 `_. - -* ``py::capsule`` objects now support the ``name`` attribute.

It's no longer needed - following a simplification of the ``py::error_already_set`` class. - `#954 `_. - -* Deprecated ``py::handle::operator==()`` in favor of ``py::handle::is()`` - `#825 `_. - -* Deprecated ``py::object::borrowed``/``py::object::stolen``. - Use ``py::object::borrowed_t{}``/``py::object::stolen_t{}`` instead. - `#771 `_. - -* Changed internal data structure versioning to avoid conflicts between - modules compiled with different revisions of pybind11. - `#1012 `_. - -* Additional compile-time and run-time error checking and more informative messages. - `#786 `_, - `#794 `_, - `#803 `_. - -* Various minor improvements and fixes. - `#764 `_, - `#791 `_, - `#795 `_, - `#840 `_, - `#844 `_, - `#846 `_, - `#849 `_, - `#858 `_, - `#862 `_, - `#871 `_, - `#872 `_, - `#881 `_, - `#888 `_, - `#899 `_, - `#928 `_, - `#931 `_, - `#944 `_, - `#950 `_, - `#952 `_, - `#962 `_, - `#965 `_, - `#970 `_, - `#978 `_, - `#979 `_, - `#986 `_, - `#1020 `_, - `#1027 `_, - `#1037 `_. - -* Testing improvements. - `#798 `_, - `#882 `_, - `#898 `_, - `#900 `_, - `#921 `_, - `#923 `_, - `#963 `_. - -v2.1.1 (April 7, 2017) ------------------------------------------------------ - -* Fixed minimum version requirement for MSVC 2015u3 - `#773 `_. - -v2.1.0 (March 22, 2017) ------------------------------------------------------ - -* pybind11 now performs function overload resolution in two phases. The first - phase only considers exact type matches, while the second allows for implicit - conversions to take place. A special ``noconvert()`` syntax can be used to - completely disable implicit conversions for specific arguments. - `#643 `_, - `#634 `_, - `#650 `_. - -* Fixed a regression where static properties no longer worked with classes - using multiple inheritance. The ``py::metaclass`` attribute is no longer - necessary (and deprecated as of this release) when binding classes with - static properties. - `#679 `_, - -* Classes bound using ``pybind11`` can now use custom metaclasses. - `#679 `_, - -* ``py::args`` and ``py::kwargs`` can now be mixed with other positional - arguments when binding functions using pybind11. - `#611 `_. - -* Improved support for C++11 unicode string and character types; added - extensive documentation regarding pybind11's string conversion behavior. - `#624 `_, - `#636 `_, - `#715 `_. - -* pybind11 can now avoid expensive copies when converting Eigen arrays to NumPy - arrays (and vice versa). `#610 `_. - -* The "fast path" in ``py::vectorize`` now works for any full-size group of C or - F-contiguous arrays. The non-fast path is also faster since it no longer performs - copies of the input arguments (except when type conversions are necessary). - `#610 `_. - -* Added fast, unchecked access to NumPy arrays via a proxy object. - `#746 `_. - -* Transparent support for class-specific ``operator new`` and - ``operator delete`` implementations. - `#755 `_. - -* Slimmer and more efficient STL-compatible iterator interface for sequence types. - `#662 `_. - -* Improved custom holder type support. - `#607 `_. - -* ``nullptr`` to ``None`` conversion fixed in various builtin type casters. - `#732 `_. - -* ``enum_`` now exposes its members via a special ``__members__`` attribute. - `#666 `_. - -* ``std::vector`` bindings created using ``stl_bind.h`` can now optionally - implement the buffer protocol. `#488 `_. - -* Automated C++ reference documentation using doxygen and breathe. - `#598 `_. - -* Added minimum compiler version assertions. - `#727 `_. - -* Improved compatibility with C++1z. - `#677 `_. - -* Improved ``py::capsule`` API.

The following list links PRs or individual commits -whenever applicable. - -Happy Christmas! - -* Support for binding C++ class hierarchies that make use of multiple - inheritance. `#410 `_. - -* PyPy support: pybind11 now supports nightly builds of PyPy and will - interoperate with the future 5.7 release. No code changes are necessary, - everything "just" works as usual. Note that we only target the Python 2.7 - branch for now; support for 3.x will be added once its ``cpyext`` extension - support catches up. A few minor features remain unsupported for the time - being (notably dynamic attributes in custom types). - `#527 `_. - -* Significant work on the documentation -- in particular, the monolithic - ``advanced.rst`` file was restructured into a easier to read hierarchical - organization. `#448 `_. - -* Many NumPy-related improvements: - - 1. Object-oriented API to access and modify NumPy ``ndarray`` instances, - replicating much of the corresponding NumPy C API functionality. - `#402 `_. - - 2. NumPy array ``dtype`` array descriptors are now first-class citizens and - are exposed via a new class ``py::dtype``. - - 3. Structured dtypes can be registered using the ``PYBIND11_NUMPY_DTYPE()`` - macro. Special ``array`` constructors accepting dtype objects were also - added. - - One potential caveat involving this change: format descriptor strings - should now be accessed via ``format_descriptor::format()`` (however, for - compatibility purposes, the old syntax ``format_descriptor::value`` will - still work for non-structured data types). `#308 - `_. - - 4. Further improvements to support structured dtypes throughout the system. - `#472 `_, - `#474 `_, - `#459 `_, - `#453 `_, - `#452 `_, and - `#505 `_. - - 5. Fast access operators. `#497 `_. - - 6. Constructors for arrays whose storage is owned by another object. - `#440 `_. - - 7. Added constructors for ``array`` and ``array_t`` explicitly accepting shape - and strides; if strides are not provided, they are deduced assuming - C-contiguity. Also added simplified constructors for 1-dimensional case. - - 8. Added buffer/NumPy support for ``char[N]`` and ``std::array`` types. - - 9. Added ``memoryview`` wrapper type which is constructible from ``buffer_info``. - -* Eigen: many additional conversions and support for non-contiguous - arrays/slices. - `#427 `_, - `#315 `_, - `#316 `_, - `#312 `_, and - `#267 `_ - -* Incompatible changes in ``class_<...>::class_()``: - - 1. Declarations of types that provide access via the buffer protocol must - now include the ``py::buffer_protocol()`` annotation as an argument to - the ``class_`` constructor. - - 2. Declarations of types that require a custom metaclass (i.e. all classes - which include static properties via commands such as - ``def_readwrite_static()``) must now include the ``py::metaclass()`` - annotation as an argument to the ``class_`` constructor. - - These two changes were necessary to make type definitions in pybind11 - future-proof, and to support PyPy via its cpyext mechanism. `#527 - `_. - - - 3. This version of pybind11 uses a redesigned mechanism for instantiating - trampoline classes that are used to override virtual methods from within - Python. This led to the following user-visible syntax change: instead of - - .. code-block:: cpp - - py::class_("MyClass") - .alias() - .... - - write - - .. code-block:: cpp - - py::class_("MyClass") - .... - - Importantly, both the original and the trampoline class are now - specified as an arguments (in arbitrary order) to the ``py::class_`` - template, and the ``alias<..>()`` call is gone. The new scheme has zero - overhead in cases when Python doesn't override any functions of the - underlying C++ class. `rev. 86d825 - `_. - -* Added ``eval`` and ``eval_file`` functions for evaluating expressions and - statements from a string or file. `rev. 0d3fc3 - `_. - -* pybind11 can now create types with a modifiable dictionary. - `#437 `_ and - `#444 `_. - -* Support for translation of arbitrary C++ exceptions to Python counterparts. - `#296 `_ and - `#273 `_. - -* Report full backtraces through mixed C++/Python code, better reporting for - import errors, fixed GIL management in exception processing. - `#537 `_, - `#494 `_, - `rev. e72d95 `_, and - `rev. 099d6e `_. - -* Support for bit-level operations, comparisons, and serialization of C++ - enumerations. `#503 `_, - `#508 `_, - `#380 `_, - `#309 `_. - `#311 `_. - -* The ``class_`` constructor now accepts its template arguments in any order. - `#385 `_. - -* Attribute and item accessors now have a more complete interface which makes - it possible to chain attributes as in - ``obj.attr("a")[key].attr("b").attr("method")(1, 2, 3)``. `#425 - `_. - -* Major redesign of the default and conversion constructors in ``pytypes.h``. - `#464 `_. - -* Added built-in support for ``std::shared_ptr`` holder type. It is no longer - necessary to to include a declaration of the form - ``PYBIND11_DECLARE_HOLDER_TYPE(T, std::shared_ptr)`` (though continuing to - do so won't cause an error). - `#454 `_. - -* New ``py::overload_cast`` casting operator to select among multiple possible - overloads of a function. An example: - - .. code-block:: cpp - - py::class_(m, "Pet") - .def("set", py::overload_cast(&Pet::set), "Set the pet's age") - .def("set", py::overload_cast(&Pet::set), "Set the pet's name"); - - This feature only works on C++14-capable compilers. - `#541 `_. - -* C++ types are automatically cast to Python types, e.g. when assigning - them as an attribute. For instance, the following is now legal: - - .. code-block:: cpp - - py::module m = /* ... */ - m.attr("constant") = 123; - - (Previously, a ``py::cast`` call was necessary to avoid a compilation error.) - `#551 `_. - -* Redesigned ``pytest``-based test suite. `#321 `_. - -* Instance tracking to detect reference leaks in test suite. `#324 `_ - -* pybind11 can now distinguish between multiple different instances that are - located at the same memory address, but which have different types. - `#329 `_. - -* Improved logic in ``move`` return value policy. - `#510 `_, - `#297 `_. - -* Generalized unpacking API to permit calling Python functions from C++ using - notation such as ``foo(a1, a2, *args, "ka"_a=1, "kb"_a=2, **kwargs)``. `#372 `_. - -* ``py::print()`` function whose behavior matches that of the native Python - ``print()`` function. `#372 `_. - -* Added ``py::dict`` keyword constructor:``auto d = dict("number"_a=42, - "name"_a="World");``. `#372 `_. - -* Added ``py::str::format()`` method and ``_s`` literal: ``py::str s = "1 + 2 - = {}"_s.format(3);``. `#372 `_. - -* Added ``py::repr()`` function which is equivalent to Python's builtin - ``repr()``. `#333 `_. - -* Improved construction and destruction logic for holder types. It is now - possible to reference instances with smart pointer holder types without - constructing the holder if desired. The ``PYBIND11_DECLARE_HOLDER_TYPE`` - macro now accepts an optional second parameter to indicate whether the holder - type uses intrusive reference counting. - `#533 `_ and - `#561 `_. - -* Mapping a stateless C++ function to Python and back is now "for free" (i.e. - no extra indirections or argument conversion overheads). `rev. 954b79 - `_. - -* Bindings for ``std::valarray``. - `#545 `_. - -* Improved support for C++17 capable compilers. - `#562 `_. - -* Bindings for ``std::optional``. - `#475 `_, - `#476 `_, - `#479 `_, - `#499 `_, and - `#501 `_. - -* ``stl_bind.h``: general improvements and support for ``std::map`` and - ``std::unordered_map``. - `#490 `_, - `#282 `_, - `#235 `_. - -* The ``std::tuple``, ``std::pair``, ``std::list``, and ``std::vector`` type - casters now accept any Python sequence type as input. `rev. 107285 - `_. - -* Improved CMake Python detection on multi-architecture Linux. - `#532 `_. - -* Infrastructure to selectively disable or enable parts of the automatically - generated docstrings. `#486 `_. - -* ``reference`` and ``reference_internal`` are now the default return value - properties for static and non-static properties, respectively. `#473 - `_. (the previous defaults - were ``automatic``). `#473 `_. - -* Support for ``std::unique_ptr`` with non-default deleters or no deleter at - all (``py::nodelete``). `#384 `_. - -* Deprecated ``handle::call()`` method. The new syntax to call Python - functions is simply ``handle()``. It can also be invoked explicitly via - ``handle::operator()``, where ``X`` is an optional return value policy. - -* Print more informative error messages when ``make_tuple()`` or ``cast()`` - fail. `#262 `_. - -* Creation of holder types for classes deriving from - ``std::enable_shared_from_this<>`` now also works for ``const`` values. - `#260 `_. - -* ``make_iterator()`` improvements for better compatibility with various - types (now uses prefix increment operator); it now also accepts iterators - with different begin/end types as long as they are equality comparable. - `#247 `_. - -* ``arg()`` now accepts a wider range of argument types for default values. - `#244 `_. - -* Support ``keep_alive`` where the nurse object may be ``None``. `#341 - `_. - -* Added constructors for ``str`` and ``bytes`` from zero-terminated char - pointers, and from char pointers and length.

Afterwards, instances will -expose fields and methods of both types: - -.. code-block:: pycon - - >>> p = example.Dog("Molly") - >>> p.name - 'Molly' - >>> p.bark() - 'woof!' - -The C++ classes defined above are regular non-polymorphic types with an -inheritance relationship.

In C++, a type is only -considered polymorphic if it has at least one virtual function and pybind11 -will automatically recognize this: - -.. code-block:: cpp - - struct PolymorphicPet { - virtual ~PolymorphicPet() = default; - }; - - struct PolymorphicDog : PolymorphicPet { - std::string bark() const { return "woof!"; } - }; - - // Same binding code - py::class_(m, "PolymorphicPet"); - py::class_(m, "PolymorphicDog") - .def(py::init<>()) - .def("bark", &PolymorphicDog::bark); - - // Again, return a base pointer to a derived instance - m.def("pet_store2", []() { return std::unique_ptr(new PolymorphicDog); }); - -.. code-block:: pycon - - >>> p = example.pet_store2() - >>> type(p) - PolymorphicDog # automatically downcast - >>> p.bark() - 'woof!' - -Given a pointer to a polymorphic base, pybind11 performs automatic downcasting -to the actual derived type.

Signature : (Pet, str) -> NoneType - | - | Set the pet's name - -If you have a C++14 compatible compiler [#cpp14]_, you can use an alternative -syntax to cast the overloaded function: - -.. code-block:: cpp - - py::class_(m, "Pet") - .def("set", py::overload_cast(&Pet::set), "Set the pet's age") - .def("set", py::overload_cast(&Pet::set), "Set the pet's name"); - -Here, ``py::overload_cast`` only requires the parameter types to be specified. -The return type and class are deduced. This avoids the additional noise of -``void (Pet::*)()`` as seen in the raw cast. If a function is overloaded based -on constness, the ``py::const_`` tag should be used: - -.. code-block:: cpp - - struct Widget { - int foo(int x, float y); - int foo(int x, float y) const; - }; - - py::class_(m, "Widget") - .def("foo_mutable", py::overload_cast(&Widget::foo)) - .def("foo_const", py::overload_cast(&Widget::foo, py::const_)); - -If you prefer the ``py::overload_cast`` syntax but have a C++11 compatible compiler only, -you can use ``py::detail::overload_cast_impl`` with an additional set of parentheses: - -.. code-block:: cpp - - template - using overload_cast_ = pybind11::detail::overload_cast_impl; - - py::class_(m, "Pet") - .def("set", overload_cast_()(&Pet::set), "Set the pet's age") - .def("set", overload_cast_()(&Pet::set), "Set the pet's name"); - -..

[python_example] https://github.com/pybind/python_example - -A helper file is provided with pybind11 that can simplify usage with setuptools. - -To use pybind11 inside your ``setup.py``, you have to have some system to -ensure that ``pybind11`` is installed when you build your package. There are -four possible ways to do this, and pybind11 supports all four: You can ask all -users to install pybind11 beforehand (bad), you can use -:ref:`setup_helpers-pep518` (good, but very new and requires Pip 10), -:ref:`setup_helpers-setup_requires` (discouraged by Python packagers now that -PEP 518 is available, but it still works everywhere), or you can -:ref:`setup_helpers-copy-manually` (always works but you have to manually sync -your copy to get updates). - -An example of a ``setup.py`` using pybind11's helpers: - -.. code-block:: python - - from glob import glob - from setuptools import setup - from pybind11.setup_helpers import Pybind11Extension - - ext_modules = [ - Pybind11Extension( - "python_example", - sorted(glob("src/*.cpp")), # Sort source files for reproducibility - ), - ] - - setup(..., ext_modules=ext_modules) - -If you want to do an automatic search for the highest supported C++ standard, -that is supported via a ``build_ext`` command override; it will only affect -``Pybind11Extensions``: - -.. code-block:: python - - from glob import glob - from setuptools import setup - from pybind11.setup_helpers import Pybind11Extension, build_ext - - ext_modules = [ - Pybind11Extension( - "python_example", - sorted(glob("src/*.cpp")), - ), - ] - - setup(..., cmdclass={"build_ext": build_ext}, ext_modules=ext_modules) - -If you have single-file extension modules that are directly stored in the -Python source tree (``foo.cpp`` in the same directory as where a ``foo.py`` -would be located), you can also generate ``Pybind11Extensions`` using -``setup_helpers.intree_extensions``: ``intree_extensions(["path/to/foo.cpp", -...])`` returns a list of ``Pybind11Extensions`` which can be passed to -``ext_modules``, possibly after further customizing their attributes -(``libraries``, ``include_dirs``, etc.). By doing so, a ``foo.*.so`` extension -module will be generated and made available upon installation. - -``intree_extension`` will automatically detect if you are using a ``src``-style -layout (as long as no namespace packages are involved), but you can also -explicitly pass ``package_dir`` to it (as in ``setuptools.setup``). - -Since pybind11 does not require NumPy when building, a light-weight replacement -for NumPy's parallel compilation distutils tool is included. Use it like this: - -.. code-block:: python - - from pybind11.setup_helpers import ParallelCompile - - # Optional multithreaded build - ParallelCompile("NPY_NUM_BUILD_JOBS").install() - - setup(...) - -The argument is the name of an environment variable to control the number of -threads, such as ``NPY_NUM_BUILD_JOBS`` (as used by NumPy), though you can set -something different if you want; ``CMAKE_BUILD_PARALLEL_LEVEL`` is another choice -a user might expect. You can also pass ``default=N`` to set the default number -of threads (0 will take the number of threads available) and ``max=N``, the -maximum number of threads; if you have a large extension you may want set this -to a memory dependent number. - -If you are developing rapidly and have a lot of C++ files, you may want to -avoid rebuilding files that have not changed. For simple cases were you are -using ``pip install -e .`` and do not have local headers, you can skip the -rebuild if an object file is newer than its source (headers are not checked!) -with the following: - -.. code-block:: python - - from pybind11.setup_helpers import ParallelCompile, naive_recompile - - ParallelCompile("NPY_NUM_BUILD_JOBS", needs_recompile=naive_recompile).install() - - -If you have a more complex build, you can implement a smarter function and pass -it to ``needs_recompile``, or you can use [Ccache]_ instead. ``CXX="cache g++" -pip install -e .`` would be the way to use it with GCC, for example. Unlike the -simple solution, this even works even when not compiling in editable mode, but -it does require Ccache to be installed. - -Keep in mind that Pip will not even attempt to rebuild if it thinks it has -already built a copy of your code, which it deduces from the version number. -One way to avoid this is to use [setuptools_scm]_, which will generate a -version number that includes the number of commits since your last tag and a -hash for a dirty directory. Another way to force a rebuild is purge your cache -or use Pip's ``--no-cache-dir`` option. - -.. [Ccache] https://ccache.dev - -.. [setuptools_scm] https://github.com/pypa/setuptools_scm - -.. _setup_helpers-pep518: - -PEP 518 requirements (Pip 10+ required) ---------------------------------------- - -If you use `PEP 518's `_ -``pyproject.toml`` file, you can ensure that ``pybind11`` is available during -the compilation of your project. When this file exists, Pip will make a new -virtual environment, download just the packages listed here in ``requires=``, -and build a wheel (binary Python package). It will then throw away the -environment, and install your wheel. - -Your ``pyproject.toml`` file will likely look something like this: - -.. code-block:: toml - - [build-system] - requires = ["setuptools>=42", "wheel", "pybind11~=2.6.1"] - build-backend = "setuptools.build_meta" - -.. note:: - - The main drawback to this method is that a `PEP 517`_ compliant build tool, - such as Pip 10+, is required for this approach to work; older versions of - Pip completely ignore this file. If you distribute binaries (called wheels - in Python) using something like `cibuildwheel`_, remember that ``setup.py`` - and ``pyproject.toml`` are not even contained in the wheel, so this high - Pip requirement is only for source builds, and will not affect users of - your binary wheels. If you are building SDists and wheels, then - `pypa-build`_ is the recommended official tool. - -.. _PEP 517: https://www.python.org/dev/peps/pep-0517/ -.. _cibuildwheel: https://cibuildwheel.readthedocs.io -.. _pypa-build: https://pypa-build.readthedocs.io/en/latest/ - -.. _setup_helpers-setup_requires: - -Classic ``setup_requires`` --------------------------- - -If you want to support old versions of Pip with the classic -``setup_requires=["pybind11"]`` keyword argument to setup, which triggers a -two-phase ``setup.py`` run, then you will need to use something like this to -ensure the first pass works (which has not yet installed the ``setup_requires`` -packages, since it can't install something it does not know about): - -.. code-block:: python - - try: - from pybind11.setup_helpers import Pybind11Extension - except ImportError: - from setuptools import Extension as Pybind11Extension - - -It doesn't matter that the Extension class is not the enhanced subclass for the -first pass run; and the second pass will have the ``setup_requires`` -requirements. - -This is obviously more of a hack than the PEP 518 method, but it supports -ancient versions of Pip. - -.. _setup_helpers-copy-manually: - -Copy manually -------------- - -You can also copy ``setup_helpers.py`` directly to your project; it was -designed to be usable standalone, like the old example ``setup.py``. You can -set ``include_pybind11=False`` to skip including the pybind11 package headers, -so you can use it with git submodules and a specific git version. If you use -this, you will need to import from a local file in ``setup.py`` and ensure the -helper file is part of your MANIFEST. - - -Closely related, if you include pybind11 as a subproject, you can run the -``setup_helpers.py`` inplace. If loaded correctly, this should even pick up -the correct include for pybind11, though you can turn it off as shown above if -you want to input it manually. - -Suggested usage if you have pybind11 as a submodule in ``extern/pybind11``: - -.. code-block:: python - - DIR = os.path.abspath(os.path.dirname(__file__)) - - sys.path.append(os.path.join(DIR, "extern", "pybind11")) - from pybind11.setup_helpers import Pybind11Extension # noqa: E402 - - del sys.path[-1] - - -.. versionchanged:: 2.6 - - Added ``setup_helpers`` file. - -Building with cppimport -======================== - -[cppimport]_ is a small Python import hook that determines whether there is a C++ -source file whose name matches the requested module. If there is, the file is -compiled as a Python extension using pybind11 and placed in the same folder as -the C++ source file. Python is then able to find the module and load it. - -.. [cppimport] https://github.com/tbenthompson/cppimport - -.. _cmake: - -Building with CMake -=================== - -For C++ codebases that have an existing CMake-based build system, a Python -extension module can be created with just a few lines of code: - -.. code-block:: cmake - - cmake_minimum_required(VERSION 3.4...3.18) - project(example LANGUAGES CXX) - - add_subdirectory(pybind11) - pybind11_add_module(example example.cpp) - -This assumes that the pybind11 repository is located in a subdirectory named -:file:`pybind11` and that the code is located in a file named :file:`example.cpp`. -The CMake command ``add_subdirectory`` will import the pybind11 project which -provides the ``pybind11_add_module`` function. It will take care of all the -details needed to build a Python extension module on any platform. - -A working sample project, including a way to invoke CMake from :file:`setup.py` for -PyPI integration, can be found in the [cmake_example]_ repository. - -.. [cmake_example] https://github.com/pybind/cmake_example - -.. versionchanged:: 2.6 - CMake 3.4+ is required. - -Further information can be found at :doc:`cmake/index`. - -pybind11_add_module -------------------- - -To ease the creation of Python extension modules, pybind11 provides a CMake -function with the following signature: - -.. code-block:: cmake - - pybind11_add_module( [MODULE | SHARED] [EXCLUDE_FROM_ALL] - [NO_EXTRAS] [THIN_LTO] [OPT_SIZE] source1 [source2 ...]) - -This function behaves very much like CMake's builtin ``add_library`` (in fact, -it's a wrapper function around that command). It will add a library target -called ```` to be built from the listed source files. In addition, it -will take care of all the Python-specific compiler and linker flags as well -as the OS- and Python-version-specific file extension. The produced target -```` can be further manipulated with regular CMake commands. - -``MODULE`` or ``SHARED`` may be given to specify the type of library. If no -type is given, ``MODULE`` is used by default which ensures the creation of a -Python-exclusive module. Specifying ``SHARED`` will create a more traditional -dynamic library which can also be linked from elsewhere. ``EXCLUDE_FROM_ALL`` -removes this target from the default build (see CMake docs for details). - -Since pybind11 is a template library, ``pybind11_add_module`` adds compiler -flags to ensure high quality code generation without bloat arising from long -symbol names and duplication of code in different translation units. It -sets default visibility to *hidden*, which is required for some pybind11 -features and functionality when attempting to load multiple pybind11 modules -compiled under different pybind11 versions. It also adds additional flags -enabling LTO (Link Time Optimization) and strip unneeded symbols. See the -:ref:`FAQ entry ` for a more detailed explanation. These -latter optimizations are never applied in ``Debug`` mode. If ``NO_EXTRAS`` is -given, they will always be disabled, even in ``Release`` mode. However, this -will result in code bloat and is generally not recommended. - -As stated above, LTO is enabled by default. Some newer compilers also support -different flavors of LTO such as `ThinLTO`_. Setting ``THIN_LTO`` will cause -the function to prefer this flavor if available. The function falls back to -regular LTO if ``-flto=thin`` is not available. If -``CMAKE_INTERPROCEDURAL_OPTIMIZATION`` is set (either ``ON`` or ``OFF``), then -that will be respected instead of the built-in flag search. - -.. note:: - - If you want to set the property form on targets or the - ``CMAKE_INTERPROCEDURAL_OPTIMIZATION_`` versions of this, you should - still use ``set(CMAKE_INTERPROCEDURAL_OPTIMIZATION OFF)`` (otherwise a - no-op) to disable pybind11's ipo flags. - -The ``OPT_SIZE`` flag enables size-based optimization equivalent to the -standard ``/Os`` or ``-Os`` compiler flags and the ``MinSizeRel`` build type, -which avoid optimizations that that can substantially increase the size of the -resulting binary. This flag is particularly useful in projects that are split -into performance-critical parts and associated bindings. In this case, we can -compile the project in release mode (and hence, optimize performance globally), -and specify ``OPT_SIZE`` for the binding target, where size might be the main -concern as performance is often less critical here. A ~25% size reduction has -been observed in practice. This flag only changes the optimization behavior at -a per-target level and takes precedence over the global CMake build type -(``Release``, ``RelWithDebInfo``) except for ``Debug`` builds, where -optimizations remain disabled. - -.. _ThinLTO: http://clang.llvm.org/docs/ThinLTO.html - -Configuration variables ------------------------ - -By default, pybind11 will compile modules with the compiler default or the -minimum standard required by pybind11, whichever is higher. You can set the -standard explicitly with -`CMAKE_CXX_STANDARD `_: - -.. code-block:: cmake - - set(CMAKE_CXX_STANDARD 14 CACHE STRING "C++ version selection") # or 11, 14, 17, 20 - set(CMAKE_CXX_STANDARD_REQUIRED ON) # optional, ensure standard is supported - set(CMAKE_CXX_EXTENSIONS OFF) # optional, keep compiler extensions off - -The variables can also be set when calling CMake from the command line using -the ``-D=`` flag. You can also manually set ``CXX_STANDARD`` -on a target or use ``target_compile_features`` on your targets - anything that -CMake supports. - -Classic Python support: The target Python version can be selected by setting -``PYBIND11_PYTHON_VERSION`` or an exact Python installation can be specified -with ``PYTHON_EXECUTABLE``. For example: - -.. code-block:: bash - - cmake -DPYBIND11_PYTHON_VERSION=3.6 .. - - # Another method: - cmake -DPYTHON_EXECUTABLE=/path/to/python .. - - # This often is a good way to get the current Python, works in environments: - cmake -DPYTHON_EXECUTABLE=$(python3 -c "import sys; print(sys.executable)") .. - - -find_package vs. add_subdirectory ---------------------------------- - -For CMake-based projects that don't include the pybind11 repository internally, -an external installation can be detected through ``find_package(pybind11)``. -See the `Config file`_ docstring for details of relevant CMake variables. - -.. code-block:: cmake - - cmake_minimum_required(VERSION 3.4...3.18) - project(example LANGUAGES CXX) - - find_package(pybind11 REQUIRED) - pybind11_add_module(example example.cpp) - -Note that ``find_package(pybind11)`` will only work correctly if pybind11 -has been correctly installed on the system, e. g. after downloading or cloning -the pybind11 repository : - -.. code-block:: bash - - # Classic CMake - cd pybind11 - mkdir build - cd build - cmake .. - make install - - # CMake 3.15+ - cd pybind11 - cmake -S . -B build - cmake --build build -j 2 # Build on 2 cores - cmake --install build - -Once detected, the aforementioned ``pybind11_add_module`` can be employed as -before. The function usage and configuration variables are identical no matter -if pybind11 is added as a subdirectory or found as an installed package. You -can refer to the same [cmake_example]_ repository for a full sample project --- just swap out ``add_subdirectory`` for ``find_package``. - -.. _Config file: https://github.com/pybind/pybind11/blob/master/tools/pybind11Config.cmake.in - - -.. _find-python-mode: - -FindPython mode ---------------- - -CMake 3.12+ (3.15+ recommended, 3.18.2+ ideal) added a new module called -FindPython that had a highly improved search algorithm and modern targets -and tools. If you use FindPython, pybind11 will detect this and use the -existing targets instead: - -.. code-block:: cmake - - cmake_minimum_required(VERSION 3.15...3.22) - project(example LANGUAGES CXX) - - find_package(Python 3.6 COMPONENTS Interpreter Development REQUIRED) - find_package(pybind11 CONFIG REQUIRED) - # or add_subdirectory(pybind11) - - pybind11_add_module(example example.cpp) - -You can also use the targets (as listed below) with FindPython. If you define -``PYBIND11_FINDPYTHON``, pybind11 will perform the FindPython step for you -(mostly useful when building pybind11's own tests, or as a way to change search -algorithms from the CMake invocation, with ``-DPYBIND11_FINDPYTHON=ON``. - -.. warning:: - - If you use FindPython to multi-target Python versions, use the individual - targets listed below, and avoid targets that directly include Python parts. - -There are `many ways to hint or force a discovery of a specific Python -installation `_), -setting ``Python_ROOT_DIR`` may be the most common one (though with -virtualenv/venv support, and Conda support, this tends to find the correct -Python version more often than the old system did). - -.. warning:: - - When the Python libraries (i.e. ``libpythonXX.a`` and ``libpythonXX.so`` - on Unix) are not available, as is the case on a manylinux image, the - ``Development`` component will not be resolved by ``FindPython``. When not - using the embedding functionality, CMake 3.18+ allows you to specify - ``Development.Module`` instead of ``Development`` to resolve this issue. - -.. versionadded:: 2.6 - -Advanced: interface library targets ------------------------------------ - -Pybind11 supports modern CMake usage patterns with a set of interface targets, -available in all modes. The targets provided are: - - ``pybind11::headers`` - Just the pybind11 headers and minimum compile requirements - - ``pybind11::pybind11`` - Python headers + ``pybind11::headers`` - - ``pybind11::python_link_helper`` - Just the "linking" part of pybind11:module - - ``pybind11::module`` - Everything for extension modules - ``pybind11::pybind11`` + ``Python::Module`` (FindPython CMake 3.15+) or ``pybind11::python_link_helper`` - - ``pybind11::embed`` - Everything for embedding the Python interpreter - ``pybind11::pybind11`` + ``Python::Python`` (FindPython) or Python libs - - ``pybind11::lto`` / ``pybind11::thin_lto`` - An alternative to `INTERPROCEDURAL_OPTIMIZATION` for adding link-time optimization. - - ``pybind11::windows_extras`` - ``/bigobj`` and ``/mp`` for MSVC. - - ``pybind11::opt_size`` - ``/Os`` for MSVC, ``-Os`` for other compilers. Does nothing for debug builds. - -Two helper functions are also provided: - - ``pybind11_strip(target)`` - Strips a target (uses ``CMAKE_STRIP`` after the target is built) - - ``pybind11_extension(target)`` - Sets the correct extension (with SOABI) for a target. - -You can use these targets to build complex applications. For example, the -``add_python_module`` function is identical to: - -.. code-block:: cmake - - cmake_minimum_required(VERSION 3.4) - project(example LANGUAGES CXX) - - find_package(pybind11 REQUIRED) # or add_subdirectory(pybind11) - - add_library(example MODULE main.cpp) - - target_link_libraries(example PRIVATE pybind11::module pybind11::lto pybind11::windows_extras) - - pybind11_extension(example) - if(NOT MSVC AND NOT ${CMAKE_BUILD_TYPE} MATCHES Debug|RelWithDebInfo) - # Strip unnecessary sections of the binary on Linux/macOS - pybind11_strip(example) - endif() - - set_target_properties(example PROPERTIES CXX_VISIBILITY_PRESET "hidden" - CUDA_VISIBILITY_PRESET "hidden") - -Instead of setting properties, you can set ``CMAKE_*`` variables to initialize these correctly. - -.. warning:: - - Since pybind11 is a metatemplate library, it is crucial that certain - compiler flags are provided to ensure high quality code generation. In - contrast to the ``pybind11_add_module()`` command, the CMake interface - provides a *composable* set of targets to ensure that you retain flexibility. - It can be especially important to provide or set these properties; the - :ref:`FAQ ` contains an explanation on why these are needed. - -.. versionadded:: 2.6 - -.. _nopython-mode: - -Advanced: NOPYTHON mode ------------------------ - -If you want complete control, you can set ``PYBIND11_NOPYTHON`` to completely -disable Python integration (this also happens if you run ``FindPython2`` and -``FindPython3`` without running ``FindPython``). This gives you complete -freedom to integrate into an existing system (like `Scikit-Build's -`_ ``PythonExtensions``). -``pybind11_add_module`` and ``pybind11_extension`` will be unavailable, and the -targets will be missing any Python specific behavior. - -.. versionadded:: 2.6 - -Embedding the Python interpreter --------------------------------- - -In addition to extension modules, pybind11 also supports embedding Python into -a C++ executable or library. In CMake, simply link with the ``pybind11::embed`` -target. It provides everything needed to get the interpreter running. The Python -headers and libraries are attached to the target. Unlike ``pybind11::module``, -there is no need to manually set any additional properties here. For more -information about usage in C++, see :doc:`/advanced/embedding`. - -.. code-block:: cmake - - cmake_minimum_required(VERSION 3.4...3.18) - project(example LANGUAGES CXX) - - find_package(pybind11 REQUIRED) # or add_subdirectory(pybind11) - - add_executable(example main.cpp) - target_link_libraries(example PRIVATE pybind11::embed) - -.. _building_manually: - -Building manually -================= - -pybind11 is a header-only library, hence it is not necessary to link against -any special libraries and there are no intermediate (magic) translation steps. - -On Linux, you can compile an example such as the one given in -:ref:`simple_example` using the following command: - -.. code-block:: bash - - $ c++ -O3 -Wall -shared -std=c++11 -fPIC $(python3 -m pybind11 --includes) example.cpp -o example$(python3-config --extension-suffix) - -The ``python3 -m pybind11 --includes`` command fetches the include paths for -both pybind11 and Python headers. This assumes that pybind11 has been installed -using ``pip`` or ``conda``. If it hasn't, you can also manually specify -``-I /include`` together with the Python includes path -``python3-config --includes``. - -On macOS: the build command is almost the same but it also requires passing -the ``-undefined dynamic_lookup`` flag so as to ignore missing symbols when -building the module: - -.. code-block:: bash - - $ c++ -O3 -Wall -shared -std=c++11 -undefined dynamic_lookup $(python3 -m pybind11 --includes) example.cpp -o example$(python3-config --extension-suffix) - -In general, it is advisable to include several additional build parameters -that can considerably reduce the size of the created binary. Refer to section -:ref:`cmake` for a detailed example of a suitable cross-platform CMake-based -build system that works on all platforms including Windows. - -.. note:: - - On Linux and macOS, it's better to (intentionally) not link against - ``libpython``. The symbols will be resolved when the extension library - is loaded into a Python binary. This is preferable because you might - have several different installations of a given Python version (e.g. the - system-provided Python, and one that ships with a piece of commercial - software). In this way, the plugin will work with both versions, instead - of possibly importing a second Python library into a process that already - contains one (which will lead to a segfault). - - -Building with Bazel -=================== - -You can build with the Bazel build system using the `pybind11_bazel -`_ repository. - -Generating binding code automatically -===================================== - -The ``Binder`` project is a tool for automatic generation of pybind11 binding -code by introspecting existing C++ codebases using LLVM/Clang.

Here are two very basic -examples: - -.. code-block:: cpp - - void increment(int &i) { i++; } - void increment_ptr(int *i) { (*i)++; } - -In Python, all arguments are passed by reference, so there is no general -issue in binding such code from Python. - -However, certain basic Python types (like ``str``, ``int``, ``bool``, -``float``, etc.) are **immutable**.

An example: - -.. code-block:: cpp - - int foo(int &i) { i++; return 123; } - -and the binding code - -.. code-block:: cpp - - m.def("foo", [](int i) { int rv = foo(i); return std::make_tuple(rv, i); }); - - -How can I reduce the build time? -================================ - -It's good practice to split binding code over multiple files, as in the -following example: - -:file:`example.cpp`: - -.. code-block:: cpp - - void init_ex1(py::module_ &); - void init_ex2(py::module_ &); - /* ... */ - - PYBIND11_MODULE(example, m) { - init_ex1(m); - init_ex2(m); - /* ... */ - } - -:file:`ex1.cpp`: - -.. code-block:: cpp - - void init_ex1(py::module_ &m) { - m.def("add", [](int a, int b) { return a + b; }); - } - -:file:`ex2.cpp`: - -.. code-block:: cpp - - void init_ex2(py::module_ &m) { - m.def("sub", [](int a, int b) { return a - b; }); - } - -:command:`python`: - -.. code-block:: pycon - - >>> import example - >>> example.add(1, 2) - 3 - >>> example.sub(1, 1) - 0 - -As shown above, the various ``init_ex`` functions should be contained in -separate files that can be compiled independently from one another, and then -linked together into the same final shared object.

While Python extension -modules are usually loaded with localized symbols (under POSIX systems -typically using ``dlopen`` with the ``RTLD_LOCAL`` flag), this Python default -can be changed, but even if it isn't it is not always enough to guarantee -complete independence of the symbols involved when not using -``-fvisibility=hidden``. - -Additionally, ``-fvisibility=hidden`` can deliver considerably binary size -savings.

This -function merely checks a flag, so its impact is negligible. When a signal has -been received, you must either explicitly interrupt execution by throwing -``py::error_already_set`` (which will propagate the existing -``KeyboardInterrupt``), or clear the error (which you usually will not want): - -.. code-block:: cpp - - PYBIND11_MODULE(example, m) - { - m.def("long running_func", []() - { - for (;;) { - if (PyErr_CheckSignals() != 0) - throw py::error_already_set(); - // Long running iteration - } - }); - } - -CMake doesn't detect the right Python version -============================================= - -The CMake-based build system will try to automatically detect the installed -version of Python and link against that. When this fails, or when there are -multiple versions of Python and it finds the wrong one, delete -``CMakeCache.txt`` and then add ``-DPYTHON_EXECUTABLE=$(which python)`` to your -CMake configure line. (Replace ``$(which python)`` with a path to python if -your prefer.) - -You can alternatively try ``-DPYBIND11_FINDPYTHON=ON``, which will activate the -new CMake FindPython support instead of pybind11's custom search. Requires -CMake 3.12+, and 3.15+ or 3.18.2+ are even better. You can set this in your -``CMakeLists.txt`` before adding or finding pybind11, as well. - -Inconsistent detection of Python version in CMake and pybind11 -============================================================== - -The functions ``find_package(PythonInterp)`` and ``find_package(PythonLibs)`` -provided by CMake for Python version detection are modified by pybind11 due to -unreliability and limitations that make them unsuitable for pybind11's needs. -Instead pybind11 provides its own, more reliable Python detection CMake code. -Conflicts can arise, however, when using pybind11 in a project that *also* uses -the CMake Python detection in a system with several Python versions installed. - -This difference may cause inconsistencies and errors if *both* mechanisms are -used in the same project. - -There are three possible solutions: - -1. Avoid using ``find_package(PythonInterp)`` and ``find_package(PythonLibs)`` - from CMake and rely on pybind11 in detecting Python version. If this is not - possible, the CMake machinery should be called *before* including pybind11. -2. Set ``PYBIND11_FINDPYTHON`` to ``True`` or use ``find_package(Python - COMPONENTS Interpreter Development)`` on modern CMake (3.12+, 3.15+ better, - 3.18.2+ best). Pybind11 in these cases uses the new CMake FindPython instead - of the old, deprecated search tools, and these modules are much better at - finding the correct Python. -3. Set ``PYBIND11_NOPYTHON`` to ``TRUE``. Pybind11 will not search for Python. - However, you will have to use the target-based system, and do more setup - yourself, because it does not know about or include things that depend on - Python, like ``pybind11_add_module``.

Sample warning: - -.. code-block:: none - - pybind11-bound class 'mymodule.Foo' is using an old-style placement-new '__init__' - which has been deprecated. See the upgrade guide in pybind11's docs. - - -Stricter enforcement of hidden symbol visibility for pybind11 modules ---------------------------------------------------------------------- - -pybind11 now tries to actively enforce hidden symbol visibility for modules. -If you're using either one of pybind11's :doc:`CMake or Python build systems -` (the two example repositories) and you haven't been exporting any -symbols, there's nothing to be concerned about. All the changes have been done -transparently in the background. If you were building manually or relied on -specific default visibility, read on. - -Setting default symbol visibility to *hidden* has always been recommended for -pybind11 (see :ref:`faq:symhidden`). On Linux and macOS, hidden symbol -visibility (in conjunction with the ``strip`` utility) yields much smaller -module binaries. `CPython's extension docs`_ also recommend hiding symbols -by default, with the goal of avoiding symbol name clashes between modules. -Starting with v2.2, pybind11 enforces this more strictly: (1) by declaring -all symbols inside the ``pybind11`` namespace as hidden and (2) by including -the ``-fvisibility=hidden`` flag on Linux and macOS (only for extension -modules, not for embedding the interpreter). - -.. _CPython's extension docs: https://docs.python.org/3/extending/extending.html#providing-a-c-api-for-an-extension-module - -The namespace-scope hidden visibility is done automatically in pybind11's -headers and it's generally transparent to users. It ensures that: - -* Modules compiled with different pybind11 versions don't clash with each other. - -* Some new features, like ``py::module_local`` bindings, can work as intended. - -The ``-fvisibility=hidden`` flag applies the same visibility to user bindings -outside of the ``pybind11`` namespace. It's now set automatic by pybind11's -CMake and Python build systems, but this needs to be done manually by users -of other build systems. Adding this flag: - -* Minimizes the chances of symbol conflicts between modules. E.g. if two - unrelated modules were statically linked to different (ABI-incompatible) - versions of the same third-party library, a symbol clash would be likely - (and would end with unpredictable results). - -* Produces smaller binaries on Linux and macOS, as pointed out previously. - -Within pybind11's CMake build system, ``pybind11_add_module`` has always been -setting the ``-fvisibility=hidden`` flag in release mode. From now on, it's -being applied unconditionally, even in debug mode and it can no longer be opted -out of with the ``NO_EXTRAS`` option. The ``pybind11::module`` target now also -adds this flag to its interface. The ``pybind11::embed`` target is unchanged. - -The most significant change here is for the ``pybind11::module`` target. If you -were previously relying on default visibility, i.e. if your Python module was -doubling as a shared library with dependents, you'll need to either export -symbols manually (recommended for cross-platform libraries) or factor out the -shared library (and have the Python module link to it like the other -dependents). As a temporary workaround, you can also restore default visibility -using the CMake code below, but this is not recommended in the long run: - -.. code-block:: cmake - - target_link_libraries(mymodule PRIVATE pybind11::module) - - add_library(restore_default_visibility INTERFACE) - target_compile_options(restore_default_visibility INTERFACE -fvisibility=default) - target_link_libraries(mymodule PRIVATE restore_default_visibility) - - -Local STL container bindings ----------------------------- - -Previous pybind11 versions could only bind types globally -- all pybind11 -modules, even unrelated ones, would have access to the same exported types. -However, this would also result in a conflict if two modules exported the -same C++ type, which is especially problematic for very common types, e.g. -``std::vector``. :ref:`module_local` were added to resolve this (see -that section for a complete usage guide). - -``py::class_`` still defaults to global bindings (because these types are -usually unique across modules), however in order to avoid clashes of opaque -types, ``py::bind_vector`` and ``py::bind_map`` will now bind STL containers -as ``py::module_local`` if their elements are: builtins (``int``, ``float``, -etc.), not bound using ``py::class_``, or bound as ``py::module_local``. For -example, this change allows multiple modules to bind ``std::vector`` -without causing conflicts. See :ref:`stl_bind` for more details. - -When upgrading to this version, if you have multiple modules which depend on -a single global binding of an STL container, note that all modules can still -accept foreign ``py::module_local`` types in the direction of Python-to-C++. -The locality only affects the C++-to-Python direction. If this is needed in -multiple modules, you'll need to either: - -* Add a copy of the same STL binding to all of the modules which need it. - -* Restore the global status of that single binding by marking it - ``py::module_local(false)``. - -The latter is an easy workaround, but in the long run it would be best to -localize all common type bindings in order to avoid conflicts with -third-party modules. - - -Negative strides for Python buffer objects and numpy arrays ------------------------------------------------------------ - -Support for negative strides required changing the integer type from unsigned -to signed in the interfaces of ``py::buffer_info`` and ``py::array``. If you -have compiler warnings enabled, you may notice some new conversion warnings -after upgrading. These can be resolved using ``static_cast``. - - -Deprecation of some ``py::object`` APIs ---------------------------------------- - -To compare ``py::object`` instances by pointer, you should now use -``obj1.is(obj2)`` which is equivalent to ``obj1 is obj2`` in Python. -Previously, pybind11 used ``operator==`` for this (``obj1 == obj2``), but -that could be confusing and is now deprecated (so that it can eventually -be replaced with proper rich object comparison in a future release). - -For classes which inherit from ``py::object``, ``borrowed`` and ``stolen`` -were previously available as protected constructor tags. Now the types -should be used directly instead: ``borrowed_t{}`` and ``stolen_t{}`` -(`#771 `_). - - -Stricter compile-time error checking ------------------------------------- - -Some error checks have been moved from run time to compile time. Notably, -automatic conversion of ``std::shared_ptr`` is not possible when ``T`` is -not directly registered with ``py::class_`` (e.g. ``std::shared_ptr`` -or ``std::shared_ptr>`` are not automatically convertible). -Attempting to bind a function with such arguments now results in a compile-time -error instead of waiting to fail at run time. - -``py::init<...>()`` constructor definitions are also stricter and now prevent -bindings which could cause unexpected behavior: - -.. code-block:: cpp - - struct Example { - Example(int &); - }; - - py::class_(m, "Example") - .def(py::init()); // OK, exact match - // .def(py::init()); // compile-time error, mismatch - -A non-``const`` lvalue reference is not allowed to bind to an rvalue. However, -note that a constructor taking ``const T &`` can still be registered using -``py::init()`` because a ``const`` lvalue reference can bind to an rvalue. - -v2.1 -==== - -Minimum compiler versions are enforced at compile time ------------------------------------------------------- - -The minimums also apply to v2.0 but the check is now explicit and a compile-time -error is raised if the compiler does not meet the requirements: - -* GCC >= 4.8 -* clang >= 3.3 (appleclang >= 5.0) -* MSVC >= 2015u3 -* Intel C++ >= 15.0 - - -The ``py::metaclass`` attribute is not required for static properties ---------------------------------------------------------------------- - -Binding classes with static properties is now possible by default. The -zero-parameter version of ``py::metaclass()`` is deprecated. However, a new -one-parameter ``py::metaclass(python_type)`` version was added for rare -cases when a custom metaclass is needed to override pybind11's default. - -.. code-block:: cpp - - // old -- emits a deprecation warning - py::class_(m, "Foo", py::metaclass()) - .def_property_readonly_static("foo", ...); - - // new -- static properties work without the attribute - py::class_(m, "Foo") - .def_property_readonly_static("foo", ...); - - // new -- advanced feature, override pybind11's default metaclass - py::class_(m, "Bar", py::metaclass(custom_python_type)) - ... - - -v2.0 -==== - -Breaking changes in ``py::class_`` ----------------------------------- - -These changes were necessary to make type definitions in pybind11 -future-proof, to support PyPy via its ``cpyext`` mechanism (`#527 -`_), and to improve efficiency -(`rev. 86d825 `_). - -1. Declarations of types that provide access via the buffer protocol must - now include the ``py::buffer_protocol()`` annotation as an argument to - the ``py::class_`` constructor. - - .. code-block:: cpp - - py::class_("Matrix", py::buffer_protocol()) - .def(py::init<...>()) - .def_buffer(...); - -2. Classes which include static properties (e.g. ``def_readwrite_static()``) - must now include the ``py::metaclass()`` attribute. Note: this requirement - has since been removed in v2.1. If you're upgrading from 1.x, it's - recommended to skip directly to v2.1 or newer. - -3. This version of pybind11 uses a redesigned mechanism for instantiating - trampoline classes that are used to override virtual methods from within - Python. This led to the following user-visible syntax change: - - .. code-block:: cpp - - // old v1.x syntax - py::class_("MyClass") - .alias() - ... - - // new v2.x syntax - py::class_("MyClass") - ... - - Importantly, both the original and the trampoline class are now specified - as arguments to the ``py::class_`` template, and the ``alias<..>()`` call - is gone. The new scheme has zero overhead in cases when Python doesn't - override any functions of the underlying C++ class. - `rev. 86d825 `_. - - The class type must be the first template argument given to ``py::class_`` - while the trampoline can be mixed in arbitrary order with other arguments - (see the following section). - - -Deprecation of the ``py::base()`` attribute ----------------------------------------------- - -``py::base()`` was deprecated in favor of specifying ``T`` as a template -argument to ``py::class_``. This new syntax also supports multiple inheritance. -Note that, while the type being exported must be the first argument in the -``py::class_`` template, the order of the following types (bases, -holder and/or trampoline) is not important. - -.. code-block:: cpp - - // old v1.x - py::class_("Derived", py::base()); - - // new v2.x - py::class_("Derived"); - - // new -- multiple inheritance - py::class_("Derived"); - - // new -- apart from `Derived` the argument order can be arbitrary - py::class_("Derived"); - - -Out-of-the-box support for ``std::shared_ptr`` ----------------------------------------------- - -The relevant type caster is now built in, so it's no longer necessary to -include a declaration of the form: - -.. code-block:: cpp - - PYBIND11_DECLARE_HOLDER_TYPE(T, std::shared_ptr) - -Continuing to do so won't cause an error or even a deprecation warning, -but it's completely redundant. - - -Deprecation of a few ``py::object`` APIs ----------------------------------------- - -All of the old-style calls emit deprecation warnings. - -+---------------------------------------+---------------------------------------------+ -| Old syntax | New syntax | -+=======================================+=============================================+ -| ``obj.call(args...)`` | ``obj(args...)`` | -+---------------------------------------+---------------------------------------------+ -| ``obj.str()`` | ``py::str(obj)`` | -+---------------------------------------+---------------------------------------------+ -| ``auto l = py::list(obj); l.check()`` | ``py::isinstance(obj)`` | -+---------------------------------------+---------------------------------------------+ -| ``py::object(ptr, true)`` | ``py::reinterpret_borrow(ptr)`` | -+---------------------------------------+---------------------------------------------+ -| ``py::object(ptr, false)`` | ``py::reinterpret_steal(ptr)`` | -+---------------------------------------+---------------------------------------------+ -| ``if (obj.attr("foo"))`` | ``if (py::hasattr(obj, "foo"))`` | -+---------------------------------------+---------------------------------------------+ -| ``if (obj["bar"])`` | ``if (obj.contains("bar"))`` | -+---------------------------------------+---------------------------------------------+ diff --git a/oxpy/pybind11/tests/CMakeLists.txt b/oxpy/pybind11/tests/CMakeLists.txt deleted file mode 100644 index b1cb222b4..000000000 --- a/oxpy/pybind11/tests/CMakeLists.txt +++ /dev/null @@ -1,583 +0,0 @@ -# CMakeLists.txt -- Build system for the pybind11 test suite -# -# Copyright (c) 2015 Wenzel Jakob -# -# All rights reserved.
