Its +goals and syntax are similar to the excellent +[Boost.Python](http://www.boost.org/doc/libs/1_58_0/libs/python/doc/) library +by David Abrahams: to minimize boilerplate code in traditional extension +modules by inferring type information using compile-time introspection. + +The main issue with Boost.Python—and the reason for creating such a similar +project—is Boost. Boost is an enormously large and complex suite of utility +libraries that works with almost every C++ compiler in existence. This +compatibility has its cost: arcane template tricks and workarounds are +necessary to support the oldest and buggiest of compiler specimens. Now that +C++11-compatible compilers are widely available, this heavy machinery has +become an excessively large and unnecessary dependency. + +Think of this library as a tiny self-contained version of Boost.Python with +everything stripped away that isn't relevant for binding generation. Without +comments, the core header files only require ~4K lines of code and depend on +Python (2.7 or 3.x, or PyPy2.7 >= 5.7) and the C++ standard library. This +compact implementation was possible thanks to some of the new C++11 language +features (specifically: tuples, lambda functions and variadic templates). Since +its creation, this library has grown beyond Boost.Python in many ways, leading +to dramatically simpler binding code in many common situations. + +Tutorial and reference documentation is provided at +[http://pybind11.readthedocs.org/en/master](http://pybind11.readthedocs.org/en/master). +A PDF version of the manual is available +[here](https://media.readthedocs.org/pdf/pybind11/master/pybind11.pdf). + +## Core features +pybind11 can map the following core C++ features to Python + +- Functions accepting and returning custom data structures per value, reference, or pointer +- Instance methods and static methods +- Overloaded functions +- Instance attributes and static attributes +- Arbitrary exception types +- Enumerations +- Callbacks +- Iterators and ranges +- Custom operators +- Single and multiple inheritance +- STL data structures +- Smart pointers with reference counting like ``std::shared_ptr`` +- Internal references with correct reference counting +- C++ classes with virtual (and pure virtual) methods can be extended in Python + +## Goodies +In addition to the core functionality, pybind11 provides some extra goodies: + +- Python 2.7, 3.x, and PyPy (PyPy2.7 >= 5.7) are supported with an + implementation-agnostic interface. + +- It is possible to bind C++11 lambda functions with captured variables. The + lambda capture data is stored inside the resulting Python function object. + +- pybind11 uses C++11 move constructors and move assignment operators whenever + possible to efficiently transfer custom data types. + +- It's easy to expose the internal storage of custom data types through + Pythons' buffer protocols. This is handy e.g. for fast conversion between + C++ matrix classes like Eigen and NumPy without expensive copy operations. + +- pybind11 can automatically vectorize functions so that they are transparently + applied to all entries of one or more NumPy array arguments. + +- Python's slice-based access and assignment operations can be supported with + just a few lines of code. + +- Everything is contained in just a few header files; there is no need to link + against any additional libraries. + +- Binaries are generally smaller by a factor of at least 2 compared to + equivalent bindings generated by Boost.Python.

There are three clock types defined by the C++11 +standard and users can define their own if needed. Each of these clocks have +different properties and when converting to and from python will give different +results. + +The first clock defined by the standard is ``std::chrono::system_clock``. This +clock measures the current date and time. However, this clock changes with to +updates to the operating system time. For example, if your time is synchronised +with a time server this clock will change. This makes this clock a poor choice +for timing purposes but good for measuring the wall time. + +The second clock defined in the standard is ``std::chrono::steady_clock``. +This clock ticks at a steady rate and is never adjusted. This makes it excellent +for timing purposes, however the value in this clock does not correspond to the +current date and time. Often this clock will be the amount of time your system +has been on, although it does not have to be. This clock will never be the same +clock as the system clock as the system clock can change but steady clocks +cannot. + +The third clock defined in the standard is ``std::chrono::high_resolution_clock``. +This clock is the clock that has the highest resolution out of the clocks in the +system. It is normally a typedef to either the system clock or the steady clock +but can be its own independent clock. This is important as when using these +conversions as the types you get in python for this clock might be different +depending on the system. +If it is a typedef of the system clock, python will get datetime objects, but if +it is a different clock they will be timedelta objects. + +Provided conversions +-------------------- + +.. rubric:: C++ to Python + +- ``std::chrono::system_clock::time_point`` → ``datetime.datetime`` + System clock times are converted to python datetime instances.

Due to its popularity and widespread adoption, pybind11 +provides transparent conversion and limited mapping support between Eigen and +Scientific Python linear algebra data types. + +To enable the built-in Eigen support you must include the optional header file +:file:`pybind11/eigen.h`. + +Pass-by-value +============= + +When binding a function with ordinary Eigen dense object arguments (for +example, ``Eigen::MatrixXd``), pybind11 will accept any input value that is +already (or convertible to) a ``numpy.ndarray`` with dimensions compatible with +the Eigen type, copy its values into a temporary Eigen variable of the +appropriate type, then call the function with this temporary variable. + +Sparse matrices are similarly copied to or from +``scipy.sparse.csr_matrix``/``scipy.sparse.csc_matrix`` objects. + +Pass-by-reference +================= + +One major limitation of the above is that every data conversion implicitly +involves a copy, which can be both expensive (for large matrices) and disallows +binding functions that change their (Matrix) arguments. Pybind11 allows you to +work around this by using Eigen's ``Eigen::Ref`` class much as you +would when writing a function taking a generic type in Eigen itself (subject to +some limitations discussed below). + +When calling a bound function accepting a ``Eigen::Ref`` +type, pybind11 will attempt to avoid copying by using an ``Eigen::Map`` object +that maps into the source ``numpy.ndarray`` data: this requires both that the +data types are the same (e.g. ``dtype='float64'`` and ``MatrixType::Scalar`` is +``double``); and that the storage is layout compatible. The latter limitation +is discussed in detail in the section below, and requires careful +consideration: by default, numpy matrices and Eigen matrices are *not* storage +compatible. + +If the numpy matrix cannot be used as is (either because its types differ, e.g. +passing an array of integers to an Eigen parameter requiring doubles, or +because the storage is incompatible), pybind11 makes a temporary copy and +passes the copy instead. + +When a bound function parameter is instead ``Eigen::Ref`` (note the +lack of ``const``), pybind11 will only allow the function to be called if it +can be mapped *and* if the numpy array is writeable (that is +``a.flags.writeable`` is true). Any access (including modification) made to +the passed variable will be transparently carried out directly on the +``numpy.ndarray``. + +This means you can can write code such as the following and have it work as +expected: + +.. code-block:: cpp + + void scale_by_2(Eigen::Ref v) { + v *= 2; + } + +Note, however, that you will likely run into limitations due to numpy and +Eigen's difference default storage order for data; see the below section on +:ref:`storage_orders` for details on how to bind code that won't run into such +limitations. + +.. note:: + + Passing by reference is not supported for sparse types. + +Returning values to Python +========================== + +When returning an ordinary dense Eigen matrix type to numpy (e.g. +``Eigen::MatrixXd`` or ``Eigen::RowVectorXf``) pybind11 keeps the matrix and +returns a numpy array that directly references the Eigen matrix: no copy of the +data is performed. The numpy array will have ``array.flags.owndata`` set to +``False`` to indicate that it does not own the data, and the lifetime of the +stored Eigen matrix will be tied to the returned ``array``. + +If you bind a function with a non-reference, ``const`` return type (e.g. +``const Eigen::MatrixXd``), the same thing happens except that pybind11 also +sets the numpy array's ``writeable`` flag to false. + +If you return an lvalue reference or pointer, the usual pybind11 rules apply, +as dictated by the binding function's return value policy (see the +documentation on :ref:`return_value_policies` for full details). 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. If the Eigen type can hold a column vector of length N it +will be passed as such a column vector. If not, but the Eigen type constraints +will accept a row vector, it will be passed as a row vector. (The column +vector takes precedence when both are supported, for example, when passing a +1D numpy array to a MatrixXd argument). Note that the type need not be +explicitly a vector: it is permitted to pass a 1D numpy array of size 5 to an +Eigen ``Matrix``: you would end up with a 1x5 Eigen matrix. +Passing the same to an ``Eigen::MatrixXd`` would result in a 5x1 Eigen matrix. + +When returning an Eigen vector to numpy, the conversion is ambiguous: a row +vector of length 4 could be returned as either a 1D array of length 4, or as a +2D array of size 1x4. When encountering such a situation, pybind11 compromises +by considering the returned Eigen type: if it is a compile-time vector--that +is, the type has either the number of rows or columns set to 1 at compile +time--pybind11 converts to a 1D numpy array when returning the value. For +instances that are a vector only at run-time (e.g. ``MatrixXd``, +``Matrix``), pybind11 returns the vector as a 2D array to +numpy. If this isn't want you want, you can use ``array.reshape(...)`` to get +a view of the same data in the desired dimensions. + +.. seealso:: + + The file :file:`tests/test_eigen.cpp` contains a complete example that + shows how to pass Eigen sparse and dense data types in more detail. diff --git a/wrap/python/pybind11/docs/advanced/cast/functional.rst b/wrap/python/pybind11/docs/advanced/cast/functional.rst new file mode 100644 index 0000000000..d9b4605759 --- /dev/null +++ b/wrap/python/pybind11/docs/advanced/cast/functional.rst @@ -0,0 +1,109 @@ +Functional +########## + +The following features must be enabled by including :file:`pybind11/functional.h`. + + +Callbacks and passing anonymous functions +========================================= + +The C++11 standard brought lambda functions and the generic polymorphic +function wrapper ``std::function<>`` to the C++ programming language, which +enable powerful new ways of working with functions.

These require a C++17 compiler and standard library. +In C++14 mode, ``std::experimental::optional<>`` is supported if available. + +Various versions of these containers also exist for C++11 (e.g. in Boost). +pybind11 provides an easy way to specialize the ``type_caster`` for such +types: + +.. code-block:: cpp + + // `boost::optional` as an example -- can be any `std::optional`-like container + namespace pybind11 { namespace detail { + template + struct type_caster> : optional_caster> {}; + }} + +The above should be placed in a header file and included in all translation units +where automatic conversion is needed. Similarly, a specialization can be provided +for custom variant types: + +.. code-block:: cpp + + // `boost::variant` as an example -- can be any `std::variant`-like container + namespace pybind11 { namespace detail { + template + struct type_caster> : variant_caster> {}; + + // Specifies the function used to visit the variant -- `apply_visitor` instead of `visit` + template <> + struct visit_helper { + template + static auto call(Args &&...args) -> decltype(boost::apply_visitor(args...)) { + return boost::apply_visitor(args...); + } + }; + }} // namespace pybind11::detail + +The ``visit_helper`` specialization is not required if your ``name::variant`` provides +a ``name::visit()`` function. For any other function name, the specialization must be +included to tell pybind11 how to visit the variant. + +.. note:: + + pybind11 only supports the modern implementation of ``boost::variant`` + which makes use of variadic templates. This requires Boost 1.56 or newer. + Additionally, on Windows, MSVC 2017 is required because ``boost::variant`` + falls back to the old non-variadic implementation on MSVC 2015. + +.. _opaque: + +Making opaque types +=================== + +pybind11 heavily relies on a template matching mechanism to convert parameters +and return values that are constructed from STL data types such as vectors, +linked lists, hash tables, etc. This even works in a recursive manner, for +instance to deal with lists of hash maps of pairs of elementary and custom +types, etc. + +However, a fundamental limitation of this approach is that internal conversions +between Python and C++ types involve a copy operation that prevents +pass-by-reference semantics. What does this mean? + +Suppose we bind the following function + +.. code-block:: cpp + + void append_1(std::vector &v) { + v.push_back(1); + } + +and call it from Python, the following happens: + +.. code-block:: pycon + + >>> v = [5, 6] + >>> append_1(v) + >>> print(v) + [5, 6] + +As you can see, when passing STL data structures by reference, modifications +are not propagated back the Python side. A similar situation arises when +exposing STL data structures using the ``def_readwrite`` or ``def_readonly`` +functions: + +.. code-block:: cpp + + /* ... definition ... */ + + class MyClass { + std::vector contents; + }; + + /* ... binding code ... */ + + py::class_(m, "MyClass") + .def(py::init<>()) + .def_readwrite("contents", &MyClass::contents); + +In this case, properties can be read and written in their entirety. However, an +``append`` operation involving such a list type has no effect: + +.. code-block:: pycon + + >>> m = MyClass() + >>> m.contents = [5, 6] + >>> print(m.contents) + [5, 6] + >>> m.contents.append(7) + >>> print(m.contents) + [5, 6] + +Finally, the involved copy operations can be costly when dealing with very +large lists. To deal with all of the above situations, pybind11 provides a +macro named ``PYBIND11_MAKE_OPAQUE(T)`` that disables the template-based +conversion machinery of types, thus rendering them *opaque*. The contents of +opaque objects are never inspected or extracted, hence they *can* be passed by +reference. For instance, to turn ``std::vector`` into an opaque type, add +the declaration + +.. code-block:: cpp + + PYBIND11_MAKE_OPAQUE(std::vector); + +before any binding code (e.g. invocations to ``class_::def()``, etc.). This +macro must be specified at the top level (and outside of any namespaces), since +it instantiates a partial template overload. If your binding code consists of +multiple compilation units, it must be present in every file (typically via a +common header) preceding any usage of ``std::vector``. Opaque types must +also have a corresponding ``class_`` declaration to associate them with a name +in Python, and to define a set of available operations, e.g.: + +.. code-block:: cpp + + py::class_>(m, "IntVector") + .def(py::init<>()) + .def("clear", &std::vector::clear) + .def("pop_back", &std::vector::pop_back) + .def("__len__", [](const std::vector &v) { return v.size(); }) + .def("__iter__", [](std::vector &v) { + return py::make_iterator(v.begin(), v.end()); + }, py::keep_alive<0, 1>()) /* Keep vector alive while iterator is used */ + // .... + +.. seealso:: + + The file :file:`tests/test_opaque_types.cpp` contains a complete + example that demonstrates how to create and expose opaque types using + pybind11 in more detail. + +.. _stl_bind: + +Binding STL containers +====================== + +The ability to expose STL containers as native Python objects is a fairly +common request, hence pybind11 also provides an optional header file named +:file:`pybind11/stl_bind.h` that does exactly this. The mapped containers try +to match the behavior of their native Python counterparts as much as possible. + +The following example showcases usage of :file:`pybind11/stl_bind.h`: + +.. code-block:: cpp + + // Don't forget this + #include + + PYBIND11_MAKE_OPAQUE(std::vector); + PYBIND11_MAKE_OPAQUE(std::map); + + // ... + + // later in binding code: + py::bind_vector>(m, "VectorInt"); + py::bind_map>(m, "MapStringDouble"); + +When binding STL containers pybind11 considers the types of the container's +elements to decide whether the container should be confined to the local module +(via the :ref:`module_local` feature). If the container element types are +anything other than already-bound custom types bound without +``py::module_local()`` the container binding will have ``py::module_local()`` +applied. This includes converting types such as numeric types, strings, Eigen +types; and types that have not yet been bound at the time of the stl container +binding. This module-local binding is designed to avoid potential conflicts +between module bindings (for example, from two separate modules each attempting +to bind ``std::vector`` as a python type). + +It is possible to override this behavior to force a definition to be either +module-local or global. To do so, you can pass the attributes +``py::module_local()`` (to make the binding module-local) or +``py::module_local(false)`` (to make the binding global) into the +``py::bind_vector`` or ``py::bind_map`` arguments: + +.. code-block:: cpp + + py::bind_vector>(m, "VectorInt", py::module_local(false)); + +Note, however, that such a global binding would make it impossible to load this +module at the same time as any other pybind module that also attempts to bind +the same container type (``std::vector`` in the above example). + +See :ref:`module_local` for more details on module-local bindings. + +.. seealso:: + + The file :file:`tests/test_stl_binders.cpp` shows how to use the + convenience STL container wrappers. diff --git a/wrap/python/pybind11/docs/advanced/cast/strings.rst b/wrap/python/pybind11/docs/advanced/cast/strings.rst new file mode 100644 index 0000000000..e25701ecab --- /dev/null +++ b/wrap/python/pybind11/docs/advanced/cast/strings.rst @@ -0,0 +1,305 @@ +Strings, bytes and Unicode conversions +###################################### + +.. note:: + + This section discusses string handling in terms of Python 3 strings.

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 overloaded 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_overload`, 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 overloaded method on the Python side. + pybind11::function overload = pybind11::get_overload(this, "myMethod"); + if (overload) { // method is found + auto obj = overload(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<>()) + +.. _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. Note that the implicit ``self`` argument +also exists in this case and is used to pass the Python ``type`` subclass +instance. This parameter will often not be needed by the C++ side, and the +following example illustrates how to instantiate a lambda getter function +that ignores it: + +.. code-block:: cpp + + py::class_(m, "Foo") + .def_property_readonly_static("foo", [](py::object /* self */) { return Foo(); }); + +Operator overloading +==================== + +Suppose that we're given the following ``Vector2`` class with a vector addition +and scalar multiplication operation, all implemented using overloaded operators +in C++. + +.. code-block:: cpp + + class Vector2 { + public: + Vector2(float x, float y) : x(x), y(y) { } + + Vector2 operator+(const Vector2 &v) const { return Vector2(x + v.x, y + v.y); } + Vector2 operator*(float value) const { return Vector2(x * value, y * value); } + Vector2& operator+=(const Vector2 &v) { x += v.x; y += v.y; return *this; } + Vector2& operator*=(float v) { x *= v; y *= v; return *this; } + + friend Vector2 operator*(float f, const Vector2 &v) { + return Vector2(f * v.x, f * v.y); + } + + std::string toString() const { + return "[" + std::to_string(x) + ", " + std::to_string(y) + "]"; + } + private: + float x, y; + }; + +The following snippet shows how the above operators can be conveniently exposed +to Python. + +.. code-block:: cpp + + #include + + PYBIND11_MODULE(example, m) { + py::class_(m, "Vector2") + .def(py::init()) + .def(py::self + py::self) + .def(py::self += py::self) + .def(py::self *= float()) + .def(float() * py::self) + .def(py::self * float()) + .def("__repr__", &Vector2::toString); + } + +Note that a line like + +.. code-block:: cpp + + .def(py::self * float()) + +is really just short hand notation for + +.. code-block:: cpp + + .def("__mul__", [](const Vector2 &a, float b) { + return a * b; + }, py::is_operator()) + +This can be useful for exposing additional operators that don't exist on the +C++ side, or to perform other types of customization. The ``py::is_operator`` +flag marker is needed to inform pybind11 that this is an operator, which +returns ``NotImplemented`` when invoked with incompatible arguments rather than +throwing a type error. + +.. note:: + + To use the more convenient ``py::self`` notation, the additional + header file :file:`pybind11/operators.h` must be included. + +.. seealso:: + + The file :file:`tests/test_operator_overloading.cpp` contains a + complete example that demonstrates how to work with overloaded operators in + more detail. + +.. _pickling: + +Pickling support +================ + +Python's ``pickle`` module provides a powerful facility to serialize and +de-serialize a Python object graph into a binary data stream. To pickle and +unpickle C++ classes using pybind11, a ``py::pickle()`` definition must be +provided. 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::picke()`` 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 + + try: + import cPickle as pickle # Use cPickle on Python 2.7 + except ImportError: + import pickle + + p = Pickleable("test_value") + p.setExtra(15) + data = pickle.dumps(p, 2) + +Note that only the cPickle module is supported on Python 2.7. The second +argument to ``dumps`` is also crucial: it selects the pickle protocol version +2, since the older version 1 is 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. + +.. 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 + +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_OVERLOAD(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`! + +.. note:: + + MSVC 2015 has a compiler bug (fixed in version 2017) which + requires a more explicit function binding in the form of + ``.def("foo", static_cast(&Publicist::foo));`` + where ``int (A::*)() const`` is the type of ``A::foo``. + +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 { + 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 + +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*``. + +..

This section will cover a few extra things required +for embedding. + +Getting started +=============== + +A basic executable with an embedded interpreter can be created with just a few +lines of CMake and the ``pybind11::embed`` target, as shown below.

The RAII guard class `scoped_interpreter` +takes care of the interpreter lifetime. After the guard is destroyed, the interpreter +shuts down and clears its memory. No Python functions can be called after this. + +Executing Python code +===================== + +There are a few different ways to run Python code. One option is to use `eval`, +`exec` or `eval_file`, as explained in :ref:`eval`. Here is a quick example in +the context of an executable with an embedded interpreter: + +.. code-block:: cpp + + #include + namespace py = pybind11; + + int main() { + py::scoped_interpreter guard{}; + + py::exec(R"( + kwargs = dict(name="World", number=42) + message = "Hello, {name}!

The answer is {number}".format(**locals()) + )", py::globals(), locals); + + auto message = locals["message"].cast(); + std::cout << message; + } + +Importing modules +================= + +Python modules can be imported using `module::import()`: + +.. code-block:: cpp + + py::module sys = py::module::import("sys"); + py::print(sys.attr("path")); + +For convenience, the current working directory is included in ``sys.path`` when +embedding the interpreter. This makes it easy to import local Python files: + +.. code-block:: python + + """calc.py located in the working directory""" + + def add(i, j): + return i + j + + +.. code-block:: cpp + + py::module calc = py::module::import("calc"); + py::object result = calc.attr("add")(1, 2); + int n = result.cast(); + assert(n == 3); + +Modules can be reloaded using `module::reload()` if the source is modified e.g. +by an external process. This can be useful in scenarios where the application +imports a user defined data processing script which needs to be updated after +changes by the user. Note that this function does not reload modules recursively. + +.. _embedding_modules: + +Adding embedded modules +======================= + +Embedded binary modules can be added using the `PYBIND11_EMBEDDED_MODULE` macro. +Note that the definition must be placed at global scope. They can be imported +like any other module. + +.. code-block:: cpp + + #include + namespace py = pybind11; + + PYBIND11_EMBEDDED_MODULE(fast_calc, m) { + // `m` is a `py::module` which is used to bind functions and classes + m.def("add", [](int i, int j) { + return i + j; + }); + } + + int main() { + py::scoped_interpreter guard{}; + + auto fast_calc = py::module::import("fast_calc"); + auto result = fast_calc.attr("add")(1, 2).cast(); + assert(result == 3); + } + +Unlike extension modules where only a single binary module can be created, on +the embedded side an unlimited number of modules can be added using multiple +`PYBIND11_EMBEDDED_MODULE` definitions (as long as they have unique names). + +These modules are added to Python's list of builtins, so they can also be +imported in pure Python files loaded by the interpreter. Everything interacts +naturally: + +.. code-block:: python + + """py_module.py located in the working directory""" + import cpp_module + + a = cpp_module.a + b = a + 1 + + +.. code-block:: cpp + + #include + namespace py = pybind11; + + PYBIND11_EMBEDDED_MODULE(cpp_module, m) { + m.attr("a") = 1; + } + + int main() { + py::scoped_interpreter guard{}; + + auto py_module = py::module::import("py_module"); + + auto locals = py::dict("fmt"_a="{} + {} = {}", **py_module.attr("__dict__")); + assert(locals["a"].cast() == 1); + assert(locals["b"].cast() == 2); + + py::exec(R"( + c = a + b + message = fmt.format(a, b, c) + )", py::globals(), locals); + + assert(locals["c"].cast() == 3); + assert(locals["message"].cast() == "1 + 2 = 3"); + } + + +Interpreter lifetime +==================== + +The Python interpreter shuts down when `scoped_interpreter` is destroyed. After +this, creating a new instance will restart the interpreter. Alternatively, the +`initialize_interpreter` / `finalize_interpreter` pair of functions can be used +to directly set the state at any time. + +Modules created with pybind11 can be safely re-initialized after the interpreter +has been restarted. However, this may not apply to third-party extension modules. +The issue is that Python itself cannot completely unload extension modules and +there are several caveats with regard to interpreter restarting. In short, not +all memory may be freed, either due to Python reference cycles or user-created +global data. All the details can be found in the CPython documentation. + +.. warning:: + + Creating two concurrent `scoped_interpreter` guards is a fatal error. So is + calling `initialize_interpreter` for a second time after the interpreter + has already been initialized. + + Do not use the raw CPython API functions ``Py_Initialize`` and + ``Py_Finalize`` as these do not properly handle the lifetime of + pybind11's internal data. + + +Sub-interpreter support +======================= + +Creating multiple copies of `scoped_interpreter` is not possible because it +represents the main Python interpreter. Sub-interpreters are something different +and they do permit the existence of multiple interpreters. This is an advanced +feature of the CPython API and should be handled with care. pybind11 does not +currently offer a C++ interface for sub-interpreters, so refer to the CPython +documentation for all the details regarding this feature. + +We'll just mention a couple of caveats the sub-interpreters support in pybind11: + + 1. Sub-interpreters will not receive independent copies of embedded modules. + Instead, these are shared and modifications in one interpreter may be + reflected in another. + + 2. Managing multiple threads, multiple interpreters and the GIL can be + challenging and there are several caveats here, even within the pure + CPython API (please refer to the Python docs for details). As for + pybind11, keep in mind that `gil_scoped_release` and `gil_scoped_acquire` + do not take sub-interpreters into account. diff --git a/wrap/python/pybind11/docs/advanced/exceptions.rst b/wrap/python/pybind11/docs/advanced/exceptions.rst new file mode 100644 index 0000000000..75ac24ae9a --- /dev/null +++ b/wrap/python/pybind11/docs/advanced/exceptions.rst @@ -0,0 +1,142 @@ +Exceptions +########## + +Built-in exception translation +============================== + +When C++ code invoked from Python throws an ``std::exception``, it is +automatically converted into a Python ``Exception``. pybind11 defines multiple +special exception classes that will map to different types of Python +exceptions: + +.. tabularcolumns:: |p{0.5\textwidth}|p{0.45\textwidth}| + ++--------------------------------------+--------------------------------------+ +| C++ exception type | Python exception type | ++======================================+======================================+ +| :class:`std::exception` | ``RuntimeError`` | ++--------------------------------------+--------------------------------------+ +| :class:`std::bad_alloc` | ``MemoryError`` | ++--------------------------------------+--------------------------------------+ +| :class:`std::domain_error` | ``ValueError`` | ++--------------------------------------+--------------------------------------+ +| :class:`std::invalid_argument` | ``ValueError`` | ++--------------------------------------+--------------------------------------+ +| :class:`std::length_error` | ``ValueError`` | ++--------------------------------------+--------------------------------------+ +| :class:`std::out_of_range` | ``IndexError`` | ++--------------------------------------+--------------------------------------+ +| :class:`std::range_error` | ``ValueError`` | ++--------------------------------------+--------------------------------------+ +| :class:`pybind11::stop_iteration` | ``StopIteration`` (used to implement | +| | custom iterators) | ++--------------------------------------+--------------------------------------+ +| :class:`pybind11::index_error` | ``IndexError`` (used to indicate out | +| | of bounds access in ``__getitem__``, | +| | ``__setitem__``, etc.) | ++--------------------------------------+--------------------------------------+ +| :class:`pybind11::value_error` | ``ValueError`` (used to indicate | +| | wrong value passed in | +| | ``container.remove(...)``) | ++--------------------------------------+--------------------------------------+ +| :class:`pybind11::key_error` | ``KeyError`` (used to indicate out | +| | of bounds access in ``__getitem__``, | +| | ``__setitem__`` in dict-like | +| | objects, etc.) | ++--------------------------------------+--------------------------------------+ +| :class:`pybind11::error_already_set` | Indicates that the Python exception | +| | flag has already been set via Python | +| | API calls from C++ code; this C++ | +| | exception is used to propagate such | +| | a Python exception back to Python. | ++--------------------------------------+--------------------------------------+ + +When a Python function invoked from C++ throws an exception, it is converted +into a C++ exception of type :class:`error_already_set` whose string payload +contains a textual summary. + +There is also a special exception :class:`cast_error` that is thrown by +:func:`handle::call` when the input arguments cannot be converted to Python +objects. + +Registering custom translators +============================== + +If the default exception conversion policy described above is insufficient, +pybind11 also provides support for registering custom exception translators. +To register a simple exception conversion that translates a C++ exception into +a new Python exception using the C++ exception's ``what()`` method, a helper +function is available: + +.. code-block:: cpp + + py::register_exception(module, "PyExp"); + +This call creates a Python exception class with the name ``PyExp`` in the given +module and automatically converts any encountered exceptions of type ``CppExp`` +into Python exceptions of type ``PyExp``. + +When more advanced exception translation is needed, the function +``py::register_exception_translator(translator)`` can be used to register +functions that can translate arbitrary exception types (and which may include +additional logic to do so). The function takes a stateless callable (e.g. a +function pointer or a lambda function without captured variables) with the call +signature ``void(std::exception_ptr)``. + +When a C++ exception is thrown, the registered exception translators are tried +in reverse order of registration (i.e. the last registered translator gets the +first shot at handling the exception). + +Inside the translator, ``std::rethrow_exception`` should be used within +a try block to re-throw the exception. One or more catch clauses to catch +the appropriate exceptions should then be used with each clause using +``PyErr_SetString`` to set a Python exception or ``ex(string)`` to set +the python exception to a custom exception type (see below). + +To declare a custom Python exception type, declare a ``py::exception`` variable +and use this in the associated exception translator (note: it is often useful +to make this a static declaration when using it inside a lambda expression +without requiring capturing). + + +The following example demonstrates this for a hypothetical exception classes +``MyCustomException`` and ``OtherException``: the first is translated to a +custom python exception ``MyCustomError``, while the second is translated to a +standard python RuntimeError: + +.. code-block:: cpp + + static py::exception exc(m, "MyCustomError"); + py::register_exception_translator([](std::exception_ptr p) { + try { + if (p) std::rethrow_exception(p); + } catch (const MyCustomException &e) { + exc(e.what()); + } catch (const OtherException &e) { + PyErr_SetString(PyExc_RuntimeError, e.what()); + } + }); + +Multiple exceptions can be handled by a single translator, as shown in the +example above. If the exception is not caught by the current translator, the +previously registered one gets a chance. + +If none of the registered exception translators is able to handle the +exception, it is handled by the default converter as described in the previous +section. + +.. seealso:: + + The file :file:`tests/test_exceptions.cpp` contains examples + of various custom exception translators and custom exception types. + +.. note:: + + You must call either ``PyErr_SetString`` or a custom exception's call + operator (``exc(string)``) for every exception caught in a custom exception + translator.

The following guide is applicable to both free and member +functions, i.e. *methods* in Python. + +.. _return_value_policies: + +Return value policies +===================== + +Python and C++ use fundamentally different ways of managing the memory and +lifetime of objects managed by them. This can lead to issues when creating +bindings for functions that return a non-trivial type. Just by looking at the +type information, it is not clear whether Python should take charge of the +returned value and eventually free its resources, or if this is handled on the +C++ side. For this reason, pybind11 provides a several *return value policy* +annotations that can be passed to the :func:`module::def` and +:func:`class_::def` functions. The default policy is +:enum:`return_value_policy::automatic`. + +Return value policies are tricky, and it's very important to get them right. +Just to illustrate what can go wrong, consider the following simple example: + +.. code-block:: cpp + + /* Function declaration */ + Data *get_data() { return _data; /* (pointer to a static data structure) */ } + ... + + /* Binding code */ + m.def("get_data", &get_data); // <-- KABOOM, will cause crash when called from Python + +What's going on here? When ``get_data()`` is called from Python, the return +value (a native C++ type) must be wrapped to turn it into a usable Python type. +In this case, the default return value policy (:enum:`return_value_policy::automatic`) +causes pybind11 to assume ownership of the static ``_data`` instance. + +When Python's garbage collector eventually deletes the Python +wrapper, pybind11 will also attempt to delete the C++ instance (via ``operator +delete()``) due to the implied ownership. At this point, the entire application +will come crashing down, though errors could also be more subtle and involve +silent data corruption. + +In the above example, the policy :enum:`return_value_policy::reference` should have +been specified so that the global data instance is only *referenced* without any +implied transfer of ownership, i.e.: + +.. code-block:: cpp + + m.def("get_data", &get_data, return_value_policy::reference); + +On the other hand, this is not the right policy for many other situations, +where ignoring ownership could lead to resource leaks. +As a developer using pybind11, it's important to be familiar with the different +return value policies, including which situation calls for which one of them. +The following table provides an overview of available policies: + +.. tabularcolumns:: |p{0.5\textwidth}|p{0.45\textwidth}| + ++--------------------------------------------------+----------------------------------------------------------------------------+ +| Return value policy | Description | ++==================================================+============================================================================+ +| :enum:`return_value_policy::take_ownership` | Reference an existing object (i.e. do not create a new copy) and take | +| | ownership. Python will call the destructor and delete operator when the | +| | object's reference count reaches zero. Undefined behavior ensues when the | +| | C++ side does the same, or when the data was not dynamically allocated. | ++--------------------------------------------------+----------------------------------------------------------------------------+ +| :enum:`return_value_policy::copy` | Create a new copy of the returned object, which will be owned by Python. | +| | This policy is comparably safe because the lifetimes of the two instances | +| | are decoupled. | ++--------------------------------------------------+----------------------------------------------------------------------------+ +| :enum:`return_value_policy::move` | Use ``std::move`` to move the return value contents into a new instance | +| | that will be owned by Python. This policy is comparably safe because the | +| | lifetimes of the two instances (move source and destination) are decoupled.| ++--------------------------------------------------+----------------------------------------------------------------------------+ +| :enum:`return_value_policy::reference` | Reference an existing object, but do not take ownership. The C++ side is | +| | responsible for managing the object's lifetime and deallocating it when | +| | it is no longer used. Warning: undefined behavior will ensue when the C++ | +| | side deletes an object that is still referenced and used by Python. | ++--------------------------------------------------+----------------------------------------------------------------------------+ +| :enum:`return_value_policy::reference_internal` | Indicates that the lifetime of the return value is tied to the lifetime | +| | of a parent object, namely the implicit ``this``, or ``self`` argument of | +| | the called method or property. Internally, this policy works just like | +| | :enum:`return_value_policy::reference` but additionally applies a | +| | ``keep_alive<0, 1>`` *call policy* (described in the next section) that | +| | prevents the parent object from being garbage collected as long as the | +| | return value is referenced by Python. This is the default policy for | +| | property getters created via ``def_property``, ``def_readwrite``, etc. | ++--------------------------------------------------+----------------------------------------------------------------------------+ +| :enum:`return_value_policy::automatic` | **Default policy.** This policy falls back to the policy | +| | :enum:`return_value_policy::take_ownership` when the return value is a | +| | pointer. Otherwise, it uses :enum:`return_value_policy::move` or | +| | :enum:`return_value_policy::copy` for rvalue and lvalue references, | +| | respectively. See above for a description of what all of these different | +| | policies do. | ++--------------------------------------------------+----------------------------------------------------------------------------+ +| :enum:`return_value_policy::automatic_reference` | As above, but use policy :enum:`return_value_policy::reference` when the | +| | return value is a pointer. This is the default conversion policy for | +| | function arguments when calling Python functions manually from C++ code | +| | (i.e. via handle::operator()). You probably won't need to use this. | ++--------------------------------------------------+----------------------------------------------------------------------------+ + +Return value policies can also be applied to properties: + +.. code-block:: cpp + + class_(m, "MyClass") + .def_property("data", &MyClass::getData, &MyClass::setData, + py::return_value_policy::copy); + +Technically, the code above applies the policy to both the getter and the +setter function, however, the setter doesn't really care about *return* +value policies which makes this a convenient terse syntax. Alternatively, +targeted arguments can be passed through the :class:`cpp_function` constructor: + +.. code-block:: cpp + + class_(m, "MyClass") + .def_property("data" + py::cpp_function(&MyClass::getData, py::return_value_policy::copy), + py::cpp_function(&MyClass::setData) + ); + +.. warning:: + + Code with invalid return value policies might access uninitialized memory or + free data structures multiple times, which can lead to hard-to-debug + non-determinism and segmentation faults, hence it is worth spending the + time to understand all the different options in the table above. + +.. note:: + + One important aspect of the above policies is that they only apply to + instances which pybind11 has *not* seen before, in which case the policy + clarifies essential questions about the return value's lifetime and + ownership. When pybind11 knows the instance already (as identified by its + type and address in memory), it will return the existing Python object + wrapper rather than creating a new copy. + +.. note:: + + The next section on :ref:`call_policies` discusses *call policies* that can be + specified *in addition* to a return value policy from the list above. 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. + +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(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, 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 as long as the ``py::args`` and ``py::kwargs`` arguments are the last +arguments accepted by the function. + +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") = (SomeType *) nullptr); + +.. _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 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. + +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. diff --git a/wrap/python/pybind11/docs/advanced/misc.rst b/wrap/python/pybind11/docs/advanced/misc.rst new file mode 100644 index 0000000000..5b38ec7598 --- /dev/null +++ b/wrap/python/pybind11/docs/advanced/misc.rst @@ -0,0 +1,306 @@ +Miscellaneous +############# + +.. _macro_notes: + +General notes regarding convenience macros +========================================== + +pybind11 provides a few convenience macros such as +:func:`PYBIND11_DECLARE_HOLDER_TYPE` and ``PYBIND11_OVERLOAD_*``. Since these +are "just" macros that are evaluated in the preprocessor (which has no concept +of types), they *will* get confused by commas in a template argument; for +example, consider: + +.. code-block:: cpp + + PYBIND11_OVERLOAD(MyReturnType, Class, func) + +The limitation of the C preprocessor interprets this as five arguments (with new +arguments beginning after each comma) rather than three. To get around this, +there are two alternatives: you can use a type alias, or you can wrap the type +using the ``PYBIND11_TYPE`` macro: + +.. code-block:: cpp + + // Version 1: using a type alias + using ReturnType = MyReturnType; + using ClassType = Class; + PYBIND11_OVERLOAD(ReturnType, ClassType, func); + + // Version 2: using the PYBIND11_TYPE macro: + PYBIND11_OVERLOAD(PYBIND11_TYPE(MyReturnType), + PYBIND11_TYPE(Class), func) + +The ``PYBIND11_MAKE_OPAQUE`` macro does *not* require the above workarounds. + +.. _gil: + +Global Interpreter Lock (GIL) +============================= + +When calling a C++ function from Python, the GIL is always held. +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. In this way, long-running C++ code can be parallelized using +multiple Python threads. Taking :ref:`overriding_virtuals` as an example, this +could be realized as follows (important changes highlighted): + +.. code-block:: cpp + :emphasize-lines: 8,9,31,32 + + class PyAnimal : public Animal { + public: + /* Inherit the constructors */ + using Animal::Animal; + + /* Trampoline (need one for each virtual function) */ + std::string go(int n_times) { + /* Acquire GIL before calling Python code */ + py::gil_scoped_acquire acquire; + + PYBIND11_OVERLOAD_PURE( + std::string, /* Return type */ + Animal, /* Parent class */ + go, /* Name of function */ + n_times /* Argument(s) */ + ); + } + }; + + PYBIND11_MODULE(example, m) { + py::class_ animal(m, "Animal"); + animal + .def(py::init<>()) + .def("go", &Animal::go); + + py::class_(m, "Dog", animal) + .def(py::init<>()); + + m.def("call_go", [](Animal *animal) -> std::string { + /* Release GIL before calling into (potentially long-running) C++ code */ + py::gil_scoped_release release; + return call_go(animal); + }); + } + +The ``call_go`` wrapper can also be simplified using the `call_guard` policy +(see :ref:`call_policies`) which yields the same result: + +.. code-block:: cpp + + m.def("call_go", &call_go, py::call_guard()); + + +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 = (MyData *) py::get_shared_data("mydata"); + if (!data) + data = (MyData *) 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 colelcted + 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 (at least version 5.9) 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"); + } + +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. Note that this feature requires the +:file:`pybind11/numpy.h` header to be included. + +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. + +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 = (double *) buf1.ptr, + *ptr2 = (double *) buf2.ptr, + *ptr3 = (double *) 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 (ssize_t i = 0; i < r.shape(0); i++) + for (ssize_t j = 0; j < r.shape(1); j++) + for (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 (ssize_t i = 0; i < r.shape(0); i++) + for (ssize_t j = 0; j < r.shape(1); j++) + for (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()``.

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. Added constructors for ``str`` + from ``bytes`` and for ``bytes`` from ``str``, which will perform UTF-8 + decoding/encoding as required. + +* Many other improvements of library internals without user-visible changes + + +1.8.1 (July 12, 2016) +---------------------- +* Fixed a rare but potentially very severe issue when the garbage collector ran + during pybind11 type creation. + +1.8.0 (June

Boost.Python's ``indexing_suite`` +* Transparent conversion of sparse and dense Eigen matrices and vectors (``eigen.h``) +* Added an ``ExtraFlags`` template argument to the NumPy ``array_t<>`` wrapper + to disable an enforced cast that may lose precision, e.g. to create overloads + for different precisions and complex vs real-valued matrices. +* Prevent implicit conversion of floating point values to integral types in + function arguments +* Fixed incorrect default return value policy for functions returning a shared + pointer +* Don't allow registering a type via ``class_`` twice +* Don't

Its definition is given below: + +.. code-block:: cpp + + struct Pet { + Pet(const std::string &name) : name(name) { } + void setName(const std::string &name_) { name = name_; } + const std::string &getName() const { return name; } + + std::string name; + }; + +The binding code for ``Pet`` looks as follows: + +.. code-block:: cpp + + #include + + namespace py = pybind11; + + PYBIND11_MODULE(example, m) { + py::class_(m, "Pet") + .def(py::init()) + .def("setName", &Pet::setName) + .def("getName", &Pet::getName); + } + +:class:`class_` creates bindings for a C++ *class* or *struct*-style data +structure. :func:`init` is a convenience function that takes the types of a +constructor's parameters as template arguments and wraps the corresponding +constructor (see the :ref:`custom_constructors` section for details). An +interactive Python session demonstrating this example is shown below: + +.. code-block:: pycon + + % python + >>> import example + >>> p = example.Pet('Molly') + >>> print(p) + + >>> p.getName() + u'Molly' + >>> p.setName('Charly') + >>> p.getName() + u'Charly' + +.. seealso:: + + Static member functions can be bound in the same way using + :func:`class_::def_static`. + +Keyword and default arguments +============================= +It is possible to specify keyword and default arguments using the syntax +discussed in the previous chapter. Refer to the sections :ref:`keyword_args` +and :ref:`default_args` for details. + +Binding lambda functions +======================== + +Note how ``print(p)`` produced a rather useless summary of our data structure in the example above: + +.. code-block:: pycon + + >>> print(p) + + +To address this, we could bind an utility function that returns a human-readable +summary to the special method slot named ``__repr__``. Unfortunately, there is no +suitable functionality in the ``Pet`` data structure, and it would be nice if +we did not have to change it. This can easily be accomplished by binding a +Lambda function instead: + +.. code-block:: cpp + + py::class_(m, "Pet") + .def(py::init()) + .def("setName", &Pet::setName) + .def("getName", &Pet::getName) + .def("__repr__", + [](const Pet &a) { + return ""; + } + ); + +Both stateless [#f1]_ and stateful lambda closures are supported by pybind11. +With the above change, the same Python code now produces the following output: + +.. code-block:: pycon + + >>> print(p) + + +.. [#f1] Stateless closures are those with an empty pair of brackets ``[]`` as the capture object. + +.. _properties: + +Instance and static fields +========================== + +We can also directly expose the ``name`` field using the +:func:`class_::def_readwrite` method. A similar :func:`class_::def_readonly` +method also exists for ``const`` fields. + +.. code-block:: cpp + + py::class_(m, "Pet") + .def(py::init()) + .def_readwrite("name", &Pet::name) + // ... remainder ... + +This makes it possible to write + +.. code-block:: pycon + + >>> p = example.Pet('Molly') + >>> p.name + u'Molly' + >>> p.name = 'Charly' + >>> p.name + u'Charly' + +Now suppose that ``Pet::name`` was a private internal variable +that can only be accessed via setters and getters. + +.. code-block:: cpp + + class Pet { + public: + Pet(const std::string &name) : name(name) { } + void setName(const std::string &name_) { name = name_; } + const std::string &getName() const { return name; } + private: + std::string name; + }; + +In this case, the method :func:`class_::def_property` +(:func:`class_::def_property_readonly` for read-only data) can be used to +provide a field-like interface within Python that will transparently call +the setter and getter functions: + +.. code-block:: cpp + + py::class_(m, "Pet") + .def(py::init()) + .def_property("name", &Pet::getName, &Pet::setName) + // ... remainder ... + +Write only properties can be defined by passing ``nullptr`` as the +input for the read function. + +.. seealso:: + + Similar functions :func:`class_::def_readwrite_static`, + :func:`class_::def_readonly_static` :func:`class_::def_property_static`, + and :func:`class_::def_property_readonly_static` are provided for binding + static variables and properties. Please also see the section on + :ref:`static_properties` in the advanced part of the documentation. + +Dynamic attributes +================== + +Native Python classes can pick up new attributes dynamically: + +.. code-block:: pycon + + >>> class Pet: + ... name = 'Molly' + ... + >>> p = Pet() + >>> p.name = 'Charly' # overwrite existing + >>> p.age = 2 # dynamically add a new attribute + +By default, classes exported from C++ do not support this and the only writable +attributes are the ones explicitly defined using :func:`class_::def_readwrite` +or :func:`class_::def_property`. + +.. code-block:: cpp + + py::class_(m, "Pet") + .def(py::init<>()) + .def_readwrite("name", &Pet::name); + +Trying to set any other attribute results in an error: + +.. code-block:: pycon + + >>> p = example.Pet() + >>> p.name = 'Charly' # OK, attribute defined in C++ + >>> p.age = 2 # fail + AttributeError: 'Pet' object has no attribute 'age' + +To enable dynamic attributes for C++ classes, the :class:`py::dynamic_attr` tag +must be added to the :class:`py::class_` constructor: + +.. code-block:: cpp + + py::class_(m, "Pet", py::dynamic_attr()) + .def(py::init<>()) + .def_readwrite("name", &Pet::name); + +Now everything works as expected: + +.. code-block:: pycon + + >>> p = example.Pet() + >>> p.name = 'Charly' # OK, overwrite value in C++ + >>> p.age = 2 # OK, dynamically add a new attribute + >>> p.__dict__ # just like a native Python class + {'age': 2} + +Note that there is a small runtime cost for a class with dynamic attributes. +Not only because of the addition of a ``__dict__``, but also because of more +expensive garbage collection tracking which must be activated to resolve +possible circular references. Native Python classes incur this same cost by +default, so this is not anything to worry about. By default, pybind11 classes +are more efficient than native Python classes. Enabling dynamic attributes +just brings them on par. + +.. _inheritance: + +Inheritance and automatic downcasting +===================================== + +Suppose now that the example consists of two data structures with an +inheritance relationship: + +.. code-block:: cpp + + struct Pet { + Pet(const std::string &name) : name(name) { } + std::string name; + }; + + struct Dog : Pet { + Dog(const std::string &name) : Pet(name) { } + std::string bark() const { return "woof!"; } + }; + +There are two different ways of indicating a hierarchical relationship to +pybind11: the first specifies the C++ base class as an extra template +parameter of the :class:`class_`: + +.. code-block:: cpp + + py::class_(m, "Pet") + .def(py::init()) + .def_readwrite("name", &Pet::name); + + // Method 1: template parameter: + py::class_(m, "Dog") + .def(py::init()) + .def("bark", &Dog::bark); + +Alternatively, we can also assign a name to the previously bound ``Pet`` +:class:`class_` object and reference it when binding the ``Dog`` class: + +.. code-block:: cpp + + py::class_ pet(m, "Pet"); + pet.def(py::init()) + .def_readwrite("name", &Pet::name); + + // Method 2: pass parent class_ object: + py::class_(m, "Dog", pet /* <- specify Python parent type */) + .def(py::init()) + .def("bark", &Dog::bark); + +Functionality-wise, both approaches are equivalent. Afterwards, instances will +expose fields and methods of both types: + +.. code-block:: pycon + + >>> p = example.Dog('Molly') + >>> p.name + u'Molly' + >>> p.bark() + u'woof!' + +The C++ classes defined above are regular non-polymorphic types with an +inheritance relationship. This is reflected in Python: + +.. code-block:: cpp + + // Return a base pointer to a derived instance + m.def("pet_store", []() { return std::unique_ptr(new Dog("Molly")); }); + +.. code-block:: pycon + + >>> p = example.pet_store() + >>> type(p) # `Dog` instance behind `Pet` pointer + Pet # no pointer downcasting for regular non-polymorphic types + >>> p.bark() + AttributeError: 'Pet' object has no attribute 'bark' + +The function returned a ``Dog`` instance, but because it's a non-polymorphic +type behind a base pointer, Python only sees a ``Pet``. 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() + u'woof!' + +Given a pointer to a polymorphic base, pybind11 performs automatic downcasting +to the actual derived type. Note that this goes beyond the usual situation in +C++: we don't just get access to the virtual functions of the base, we get the +concrete derived type including functions and attributes that the base type may +not even be aware of. + +.. seealso:: + + For more information about polymorphic behavior see :ref:`overriding_virtuals`. + + +Overloaded methods +================== + +Sometimes there are several overloaded C++ methods with the same name taking +different kinds of input arguments: + +.. code-block:: cpp + + struct Pet { + Pet(const std::string &name, int age) : name(name), age(age) { } + + void set(int age_) { age = age_; } + void set(const std::string &name_) { name = name_; } + + std::string name; + int age; + }; + +Attempting to bind ``Pet::set`` will cause an error since the compiler does not +know which method the user intended to select. We can disambiguate by casting +them to function pointers. Binding multiple functions to the same Python name +automatically creates a chain of function overloads that will be tried in +sequence. + +.. code-block:: cpp + + py::class_(m, "Pet") + .def(py::init()) + .def("set", (void (Pet::*)(int)) &Pet::set, "Set the pet's age") + .def("set", (void (Pet::*)(const std::string &)) &Pet::set, "Set the pet's name"); + +The overload signatures are also visible in the method's docstring: + +.. code-block:: pycon + + >>> help(example.Pet) + + class Pet(__builtin__.object) + | Methods defined here: + | + | __init__(...) + | Signature : (Pet, str, int) -> NoneType + | + | set(...) + | 1. Signature : (Pet, int) -> NoneType + | + | Set the pet's age + | + | 2. 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_)); + + +.. [#cpp14] A compiler which supports the ``-std=c++14`` flag + or Visual Studio 2015 Update 2 and newer. + +.. note:: + + To define multiple overloaded constructors, simply declare one after the + other using the ``.def(py::init<...>())`` syntax. The existing machinery + for specifying keyword and default arguments also works. + +Enumerations and internal types +=============================== + +Let's now suppose that the example class contains an internal enumeration type, +e.g.: + +.. code-block:: cpp + + struct Pet { + enum Kind { + Dog = 0, + Cat + }; + + Pet(const std::string &name, Kind type) : name(name), type(type) { } + + std::string name; + Kind type; + }; + +The binding code for this example looks as follows: + +.. code-block:: cpp + + py::class_ pet(m, "Pet"); + + pet.def(py::init()) + .def_readwrite("name", &Pet::name) + .def_readwrite("type", &Pet::type); + + py::enum_(pet, "Kind") + .value("Dog", Pet::Kind::Dog) + .value("Cat", Pet::Kind::Cat) + .export_values(); + +To ensure that the ``Kind`` type is created within the scope of ``Pet``, the +``pet`` :class:`class_` instance must be supplied to the :class:`enum_`. +constructor. The :func:`enum_::export_values` function exports the enum entries +into the parent scope, which should be skipped for newer C++11-style strongly +typed enums. + +.. code-block:: pycon + + >>> p = Pet('Lucy', Pet.Cat) + >>> p.type + Kind.Cat + >>> int(p.type) + 1L + +The entries defined by the enumeration type are exposed in the ``__members__`` property: + +.. code-block:: pycon + + >>> Pet.Kind.__members__ + {'Dog': Kind.Dog, 'Cat': Kind.Cat} + +The ``name`` property returns the name of the enum value as a unicode string. + +.. note:: + + It is also possible to use ``str(enum)``, however these accomplish different + goals. The following shows how these two approaches differ. + + .. code-block:: pycon + + >>> p = Pet( "Lucy", Pet.Cat ) + >>> pet_type = p.type + >>> pet_type + Pet.Cat + >>> str(pet_type) + 'Pet.Cat' + >>> pet_type.name + 'Cat' + +.. note:: + + When the special tag ``py::arithmetic()`` is specified to the ``enum_`` + constructor, pybind11 creates an enumeration that also supports rudimentary + arithmetic and bit-level operations like comparisons, and, or, xor, negation, + etc. + + .. code-block:: cpp + + py::enum_(pet, "Kind", py::arithmetic()) + ... + + By default, these are omitted to conserve space. diff --git a/wrap/python/pybind11/docs/compiling.rst b/wrap/python/pybind11/docs/compiling.rst new file mode 100644 index 0000000000..c50c7d8afb --- /dev/null +++ b/wrap/python/pybind11/docs/compiling.rst @@ -0,0 +1,289 @@ +.. _compiling: + +Build systems +############# + +Building with setuptools +======================== + +For projects on PyPI, building with setuptools is the way to go.

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 + +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] [SYSTEM] [THIN_LTO] 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. + +By default, pybind11 and Python headers will be included with ``-I``. In order +to include pybind11 as system library, e.g. to avoid warnings in downstream +code with warn-levels outside of pybind11's scope, set the option ``SYSTEM``. + +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. + +.. _ThinLTO: http://clang.llvm.org/docs/ThinLTO.html + +Configuration variables +----------------------- + +By default, pybind11 will compile modules with the C++14 standard, if available +on the target compiler, falling back to C++11 if C++14 support is not +available. Note, however, that this default is subject to change: future +pybind11 releases are expected to migrate to newer C++ standards as they become +available. To override this, the standard flag can be given explicitly in +``PYBIND11_CPP_STANDARD``: + +.. code-block:: cmake + + # Use just one of these: + # GCC/clang: + set(PYBIND11_CPP_STANDARD -std=c++11) + set(PYBIND11_CPP_STANDARD -std=c++14) + set(PYBIND11_CPP_STANDARD -std=c++1z) # Experimental C++17 support + # MSVC: + set(PYBIND11_CPP_STANDARD /std:c++14) + set(PYBIND11_CPP_STANDARD /std:c++latest) # Enables some MSVC C++17 features + + add_subdirectory(pybind11) # or find_package(pybind11) + +Note that this and all other configuration variables must be set **before** the +call to ``add_subdirectory`` or ``find_package``. The variables can also be set +when calling CMake from the command line using the ``-D=`` flag. + +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 .. + # or + cmake -DPYTHON_EXECUTABLE=path/to/python .. + +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 2.8.12) + project(example) + + 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 + + cd pybind11 + mkdir build + cd build + cmake .. + make install + +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 + +Advanced: interface library target +---------------------------------- + +When using a version of CMake greater than 3.0, pybind11 can additionally +be used as a special *interface library* . The target ``pybind11::module`` +is available with pybind11 headers, Python headers and libraries as needed, +and C++ compile definitions attached. This target is suitable for linking +to an independently constructed (through ``add_library``, not +``pybind11_add_module``) target in the consuming project. + +.. code-block:: cmake + + cmake_minimum_required(VERSION 3.0) + project(example) + + find_package(pybind11 REQUIRED) # or add_subdirectory(pybind11) + + add_library(example MODULE main.cpp) + target_link_libraries(example PRIVATE pybind11::module) + set_target_properties(example PROPERTIES PREFIX "${PYTHON_MODULE_PREFIX}" + SUFFIX "${PYTHON_MODULE_EXTENSION}") + +.. 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 + library only provides the *minimal* set of parameters to ensure that the + code using pybind11 compiles, but it does **not** pass these extra compiler + flags (i.e. this is up to you). + + These include Link Time Optimization (``-flto`` on GCC/Clang/ICPC, ``/GL`` + and ``/LTCG`` on Visual Studio) and .OBJ files with many sections on Visual + Studio (``/bigobj``). The :ref:`FAQ ` contains an + explanation on why these are needed. + +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 3.0) + project(example) + + 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 flags given here assume that you're using Python 3. For Python 2, just +change the executable appropriately (to ``python`` or ``python2``). + +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``. + +Note that Python 2.7 modules don't use a special suffix, so you should simply +use ``example.so`` instead of ``example`python3-config --extension-suffix```. +Besides, the ``--extension-suffix`` option may or may not be available, depending +on the distribution; in the latter case, the module extension can be manually +set to ``.so``. + +On Mac OS: 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). + +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.

When this fails, or when there are +multiple versions of Python and it finds the wrong one, delete +``CMakeCache.txt`` and then invoke CMake as follows: + +.. code-block:: bash + + cmake -DPYTHON_EXECUTABLE:FILEPATH= . + +.. _faq_reference_arguments: + +Limitations involving reference arguments +========================================= + +In C++, it's fairly common to pass arguments using mutable references or +mutable pointers, which allows both read and write access to the value +supplied by the caller. This is sometimes done for efficiency reasons, or to +realize functions that have multiple return values. 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**. This means that the following attempt +to port the function to Python doesn't have the same effect on the value +provided by the caller -- in fact, it does nothing at all. + +.. code-block:: python + + def increment(i): + i += 1 # nope.. + +pybind11 is also affected by such language-level conventions, which means that +binding ``increment`` or ``increment_ptr`` will also create Python functions +that don't modify their arguments. + +Although inconvenient, one workaround is to encapsulate the immutable types in +a custom type that does allow modifications. + +An other alternative involves binding a small wrapper lambda function that +returns a tuple with all output arguments (see the remainder of the +documentation for examples on binding lambda functions). 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. Following this approach +will: + +1. reduce memory requirements per compilation unit. + +2. enable parallel builds (if desired). + +3. allow for faster incremental builds. For instance, when a single class + definition is changed, only a subset of the binding code will generally need + to be recompiled. + +"recursive template instantiation exceeded maximum depth of 256" +================================================================ + +If you receive an error about excessive recursive template evaluation, try +specifying a larger value, e.g. ``-ftemplate-depth=1024`` on GCC/Clang. The +culprit is generally the generation of function signatures at compile time +using C++14 template metaprogramming. + +.. _`faq:hidden_visibility`: + +"‘SomeClass’ declared with greater visibility than the type of its field ‘SomeClass::member’ [-Wattributes]" +============================================================================================================ + +This error typically indicates that you are compiling without the required +``-fvisibility`` flag. pybind11 code internally forces hidden visibility on +all internal code, but if non-hidden (and thus *exported*) code attempts to +include a pybind type (for example, ``py::object`` or ``py::list``) you can run +into this warning. + +To avoid it, make sure you are specifying ``-fvisibility=hidden`` when +compiling pybind code. + +As to why ``-fvisibility=hidden`` is necessary, because pybind modules could +have been compiled under different versions of pybind itself, it is also +important that the symbols defined in one module do not clash with the +potentially-incompatible symbols defined in another. 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, ``-fvisiblity=hidden`` can deliver considerably binary size +savings. (See the following section for more details). + + +.. _`faq:symhidden`: + +How can I create smaller binaries? +================================== + +To do its job, pybind11 extensively relies on a programming technique known as +*template metaprogramming*, which is a way of performing computation at compile +time using type information. Template metaprogamming usually instantiates code +involving significant numbers of deeply nested types that are either completely +removed or reduced to just a few instructions during the compiler's optimization +phase. However, due to the nested nature of these types, the resulting symbol +names in the compiled extension library can be extremely long. For instance, +the included test suite contains the following symbol: + +.. only:: html + + .. code-block:: none + + _​_​Z​N​8​p​y​b​i​n​d​1​1​1​2​c​p​p​_​f​u​n​c​t​i​o​n​C​1​I​v​8​E​x​a​m​p​l​e​2​J​R​N​S​t​3​_​_​1​6​v​e​c​t​o​r​I​N​S​3​_​1​2​b​a​s​i​c​_​s​t​r​i​n​g​I​w​N​S​3​_​1​1​c​h​a​r​_​t​r​a​i​t​s​I​w​E​E​N​S​3​_​9​a​l​l​o​c​a​t​o​r​I​w​E​E​E​E​N​S​8​_​I​S​A​_​E​E​E​E​E​J​N​S​_​4​n​a​m​e​E​N​S​_​7​s​i​b​l​i​n​g​E​N​S​_​9​i​s​_​m​e​t​h​o​d​E​A​2​8​_​c​E​E​E​M​T​0​_​F​T​_​D​p​T​1​_​E​D​p​R​K​T​2​_ + +.. only:: not html + + .. code-block:: cpp + + __ZN8pybind1112cpp_functionC1Iv8Example2JRNSt3__16vectorINS3_12basic_stringIwNS3_11char_traitsIwEENS3_9allocatorIwEEEENS8_ISA_EEEEEJNS_4nameENS_7siblingENS_9is_methodEA28_cEEEMT0_FT_DpT1_EDpRKT2_ + +which is the mangled form of the following function type: + +.. code-block:: cpp + + pybind11::cpp_function::cpp_function, std::__1::allocator >, std::__1::allocator, std::__1::allocator > > >&, pybind11::name, pybind11::sibling, pybind11::is_method, char [28]>(void (Example2::*)(std::__1::vector, std::__1::allocator >, std::__1::allocator, std::__1::allocator > > >&), pybind11::name const&, pybind11::sibling const&, pybind11::is_method const&, char const (&) [28]) + +The memory needed to store just the mangled name of this function (196 bytes) +is larger than the actual piece of code (111 bytes) it represents! On the other +hand, it's silly to even give this function a name -- after all, it's just a +tiny cog in a bigger piece of machinery that is not exposed to the outside +world. So we'll generally only want to export symbols for those functions which +are actually called from the outside. + +This can be achieved by specifying the parameter ``-fvisibility=hidden`` to GCC +and Clang, which sets the default symbol visibility to *hidden*, which has a +tremendous impact on the final binary size of the resulting extension library. +(On Visual Studio, symbols are already hidden by default, so nothing needs to +be done there.) + +In addition to decreasing binary size, ``-fvisibility=hidden`` also avoids +potential serious issues when loading multiple modules and is required for +proper pybind operation. See the previous FAQ entry for more details. + +Working with ancient Visual Studio 2008 builds on Windows +========================================================= + +The official Windows distributions of Python are compiled using truly +ancient versions of Visual Studio that lack good C++11 support. Some users +implicitly assume that it would be impossible to load a plugin built with +Visual Studio 2015 into a Python distribution that was compiled using Visual +Studio 2008. However, no such issue exists: it's perfectly legitimate to +interface DLLs that are built with different compilers and/or C libraries. +Common gotchas to watch out for involve not ``free()``-ing memory region +that that were ``malloc()``-ed in another shared library, using data +structures with incompatible ABIs, and so on. pybind11 is very careful not +to make these types of mistakes. + +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 not used by pybind11 due to unreliability and limitations that make +them unsuitable for pybind11's needs. Instead pybind 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. Consider the following +Cmake code executed in a system with Python 2.7 and 3.x installed: + +.. code-block:: cmake + + find_package(PythonInterp) + find_package(PythonLibs) + find_package(pybind11) + +It will detect Python 2.7 and pybind11 will pick it as well. + +In contrast this code: + +.. code-block:: cmake + + find_package(pybind11) + find_package(PythonInterp) + find_package(PythonLibs) + +will detect Python 3.x for pybind11 and may crash on ``find_package(PythonLibs)`` afterwards. + +It is advised to avoid using ``find_package(PythonInterp)`` and ``find_package(PythonLibs)`` from CMake and rely +on pybind11 in detecting Python version.

Its +goals and syntax are similar to the excellent `Boost.Python`_ library by David +Abrahams: to minimize boilerplate code in traditional extension modules by +inferring type information using compile-time introspection. + +.. _Boost.Python: http://www.boost.org/doc/libs/release/libs/python/doc/index.html + +The main issue with Boost.Python—and the reason for creating such a similar +project—is Boost. Boost is an enormously large and complex suite of utility +libraries that works with almost every C++ compiler in existence. This +compatibility has its cost: arcane template tricks and workarounds are +necessary to support the oldest and buggiest of compiler specimens. Now that +C++11-compatible compilers are widely available, this heavy machinery has +become an excessively large and unnecessary dependency. +Think of this library as a tiny self-contained version of Boost.Python with +everything stripped away that isn't relevant for binding generation. Without +comments, the core header files only require ~4K lines of code and depend on +Python (2.7 or 3.x, or PyPy2.7 >= 5.7) and the C++ standard library.

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 it's 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/wrap/python/pybind11/include/pybind11/attr.h b/wrap/python/pybind11/include/pybind11/attr.h new file mode 100644 index 0000000000..6962d6fc53 --- /dev/null +++ b/wrap/python/pybind11/include/pybind11/attr.h @@ -0,0 +1,493 @@ +/* + pybind11/attr.h: Infrastructure for processing custom + type and function attributes + + Copyright (c) 2016 Wenzel Jakob + + All rights reserved.

Boost is an enormously large and complex suite of utility +libraries that works with almost every C++ compiler in existence. This +compatibility has its cost: arcane template tricks and workarounds are +necessary to support the oldest and buggiest of compiler specimens. Now that +C++11-compatible compilers are widely available, this heavy machinery has +become an excessively large and unnecessary dependency. + +Think of this library as a tiny self-contained version of Boost.Python with +everything stripped away that isn't relevant for binding generation. Without +comments, the core header files only require ~4K lines of code and depend on +Python (2.7 or 3.x, or PyPy2.7 >= 5.7) and the C++ standard library. This +compact implementation was possible thanks to some of the new C++11 language +features (specifically: tuples, lambda functions and variadic templates). Since +its creation, this library has grown beyond Boost.Python in many ways, leading +to dramatically simpler binding code in many common situations.""") diff --git a/wrap/python/pybind11/tests/CMakeLists.txt b/wrap/python/pybind11/tests/CMakeLists.txt new file mode 100644 index 0000000000..9a701108ce --- /dev/null +++ b/wrap/python/pybind11/tests/CMakeLists.txt @@ -0,0 +1,239 @@ +# CMakeLists.txt -- Build system for the pybind11 test suite +# +# Copyright (c) 2015 Wenzel Jakob +# +# All rights reserved.

This bug causes the test below to fail, so I'm leaving it * commented out until the underlying bug in GTSAM is fixed. * From 3f8bb104053a3d1451c9d03878f310aa53b1c84e Mon Sep 17 00:00:00 2001 From: yetongumich Date: Sun, 5 Apr 2020 18:44:56 -0400 Subject: [PATCH 119/412] modified document, remove commented function, add deprecated distance --- doc/robust.pdf | Bin 197566 -> 197679 bytes gtsam/linear/NoiseModel.cpp | 5 ----- gtsam/linear/NoiseModel.h | 12 ++++++++---- 3 files changed, 8 insertions(+), 9 deletions(-) diff --git a/doc/robust.pdf b/doc/robust.pdf index 3404719b492e481bb77b96853eea0fa3a2fc39ba..ef8dc6fe624ef0af97973b383042940993273752 100644 GIT binary patch delta 2581 zcmbuB`9Bj51IKN1-$%J}tTG|Bi_J=7aurcx`1W0Fvr#?H2^FTfrYKj|q&bqucbHr5 z9GNQ;5$cPm_)4zOG{^IOJwH6J*Yo`Pe13SpUZ3}0@NP|%EoaK6LJ=r51`M?aUjf5m z7#J9CW(FpJq0V6V-_`~UN5Ehh6EM^X{5M?xmS`jbUP*)it{@Qz@c#^Y&Ki8h+=q;y z5-}!7D$I&r1cSklWFHKfXhI|+&?GX23OAu(C}af6 z42_|nGd=+f&&Xd^{G;-KH8(!Se(xE0c;^^1(;w8Y3OZ-2A*Xod8kCuQQ6eoQ!FwGF zQkkPa#8>pnCO^}=r6!QXCtrhZGiaL?xFgu#-eZ@c0L<> zL<1RzgjD}1NxtkO^mDV5Mxt+BeZc2L=ZFKk_^f#fXr!Un%bh~griQRJ zT-5u53K&xHgL+B@k|WDmW30FvoU&siXb|D)eqEJu_*t3z!j*l0)~32c%^9BWfWc8M z=Z+Kbcs4!f6(Lku)g;pmI64gTiU}sV{V^BW&xC8%ait^^w*OH}O)lB#rb0Zhq2A{O zEgu6Dxc;*!SH6Lv-=}Z~oP{yB07ADuDxKz~5Y^BbE5n}V)ejIBpr_SNh5K8)3(u#G zpbot^T}DJs;X6^1av#jf!k)kM^V`bZnmd9f(C=JoBJ3-NXTdLgx}Jh&)~s1J83jD4 zPD(L_8x$v{pX!N9LKzh$k{PR3Z5^U7FDMFD>W7r?;;zBON<=u_iOOoC_Yrrip zP0#!04yr#+ry9@U+iS-iui>OuV+WR(cI~nW9W&o#i#kqB-F{0bvdm}TpSGM9V#J3W z>2vj2%6r@vCmrYO|4h&J6SGUli{@Jtq_U+UQCCS#eo{k{9GjXUXLTz@q9-ctm*qi% zi)5vqjf;TdnJ=)7Us6K)Jv|Ve7aHt7?sIP8O+3NSD#c@R^!JHag3UAJ=_@k+CzA?7 zLZZ~eVlpyQPLBrbYEcjD@zzXaMGkHO=rOnBDwc2~t@y9eB~_3F->}f?QB!7CLH&A!A8yi!El(k^(ZA zxd4xnAXEP~7mE4$GK{0jk~%$WQl&EUj`8!Z7cqaefPLcffwy9(- zE7ADvNkz6OY;iKC^oBQcDnZAwpat|>U_#xU1|LB1;-^g&oR{D+Iwk|R@MWE5EBo{F zgNcZN=@S?*m`PgnqrdJa!^?Bot2vrK-q=QP&|e?Ib)u!`(hh(9Ud?YdD~Wq#u$-Mdf&xb2XaUon_=^+x{=}@1v0dycKT<+?HmBz?Q_nIq7NJz zr^0aWl#^UAF|Qm)D(6#oydNq%Wur7+)LEj?l$BpC#2x7BzN8D z^524B<87@c>9Hq>PHe5x`W0{d5&4;C6b|bGJ8*sSWk*q~*LZ{2#@BAIIEm<8w>-?W z>3AmhR&ov_QB6kk?y5zVa0FqwSzM-{YyUT z2VJqsZOx$yfvO;=p=;c^#zKwt1mMapc+1o>Xz750bPMqQ_9~Nh&keoin$H4#+y)L8 z4&Qlmyn>s2$vx()>np-X4euhoOp=yb;_x7y4j-|($kN)Wmr9xH;`BVock9ZRa^O#W zwz9ufxG{Rla9#YWgayYeC$QTE%ga5#J%r6H2x`GD7t++7u8n?04BiiX3tZFOhd<7& z(+g^8e6a6OFaBb2xrO|r;;Q~8Ua^SZxI&U_OUZ^K%3WrM>Y<%W6#qlYKm5q6`#GL; zoik%v^~oCMtY2-6e3jlWGCTJjwD@Qt?+}f?RId}m5Oz=-WJW3?;i}#$!Q#Eq3*3}_ zsQ7cA_!l3SaY3kJ%+KTgpg?7QJ`KcV+46B9hsAi*|Q7@yv1tg;Okng5s zIT4}i2RWk2bO1HAM+sE^NUYS!U_hFBL=m?y@t)R6jD^T0LgWB1AacN~8xp1ngb4x( zW8DLQApbda0MIJ{GX1(5D;)^3qyPVjgeCk}dyq*Y0DW72Nr%}G zc$3R{bAozU`Y(VBMXv}fm=kYvs%qCsR_~3dB1|+lvq=SLo4+WlTrQ)zDBT}?U}OkC z*x`$!iW9^0wX%c-5L9Vy;Uoxjx|u9=OE6DHILm1WxxNVk*YBap22lHPo zE^ZDw$B<}nGct3sf)?d!vV9QD6=F2wu|wI&tT~N}DIT(~YFyc^S^Ko>=G(?pzci8e zyWvuCBXlER6o0;iJQDFxB<#30qS)Rt*Y0HCsE&dThaf$C%b~3B>9?B~Bnvzk)0yv2 zOG`!M=|V}4!(q?1-R&Vc_B&71=X#*uqvm6myHrqzHhK-7kFx2?F+VWpnc>jS&;fYK zbT_Spf4y1nu4<ZS*ON)FH;-Mn{2^y6TSsn@2mit`Y!A|&I;MW0$;u%^#)(BnXJ>4xRDy0Ad9bE8s^ z=N=-i`*@eOMAY!3`b}&8*yl;=WGK2LbeVR2(S1!Xm_e>A`t?R2f39k@Hq%S0Cx9>* zdO7cRyq9ur7acmZv++z@p(B|Rp1eR+o^i07bg-?d$YO+}(UW%&^j~sGC%yKvbOUx4 zjYBK@8%_~0aZIvGj|PGxGongWeo>|Hf;rx0AK))`^ZD`D8nIaFJ@ZXVDjCpdrX}N_ zO&;{cc%o{LV7Fb$ejVrNH%Hh%oC|6nPrvXnjHRTawy$$uOY7!ui7}v~r1-kpv^a5( z9DiQ&3c1f<3`AZ*d=Rv+_=A}quf(#LfT$hT)XEkzRv*DxUr@ZpBLmK zZab_f_KV-1dL?Ad=x(xhtxa0_8aeX}%@+s+^PdUePUkvQpsn&X`Nx-r$CEuKn(U|j zj}6Nam-c|)%*C7dhS94AFNeg6q6&SHh~R*|U$QSFE8Is~Ug=f6a<=vFQE$QWEN2H* zsW_RpDt01O1M0#6Rn>x4lfMAI#>ZYJUwRAP+%N)F6U@Io4*OJX;9ls~p=-w5QWZ}0 zcD1Z7i5@pC-MGO~@(?>M75f+Sa4k9-NMY7}19;?DNjTaka<92xjtC!G{^u9{ z;d=3R^sb_z-mauOK|KzjOZHC=It<-tuVL$&gbypSZ0FX0%vY<-?TFp(`e8b|A<4)F zqRR(foKhRi565;@8hy0x*cQ2|xUl`^Kr%%A(nb9Qx+&(Jx$c2X0R&(+0h(zmt5$|%zXb(*f8bKS5jpVrcg%I~+gHR$q2=0kOh2Ix$!
