----------------------------------------------------- -----------------------------------------------------
* TBD * Support for embedding the Python interpreter. See the
:doc:`documentation page </advanced/embedding>` for a
full overview of the new features.
`#774 <https://github.com/pybind/pybind11/pull/774>`_,
`#889 <https://github.com/pybind/pybind11/pull/889>`_,
`#892 <https://github.com/pybind/pybind11/pull/892>`_,
`#920 <https://github.com/pybind/pybind11/pull/920>`_.
.. code-block:: cpp
#include <pybind11/embed.h>
namespace py = pybind11;
int main() {
py::scoped_interpreter guard{}; // start the interpreter and keep it alive
py::print("Hello, World!"); // use the Python API
}
* Support for inheriting from multiple C++ bases in Python.
`#693 <https://github.com/pybind/pybind11/pull/693>`_.
.. code-block:: python
from cpp_module import CppBase1, CppBase2
class PyDerived(CppBase1, CppBase2):
def __init__(self):
CppBase1.__init__(self) # C++ bases must be initialized explicitly
CppBase2.__init__(self)
* ``PYBIND11_MODULE`` is now the preferred way to create module entry points.
``PYBIND11_PLUGIN`` is deprecated. See :ref:`macros` for details.
`#879 <https://github.com/pybind/pybind11/pull/879>`_.
.. code-block:: cpp
// new
PYBIND11_MODULE(example, m) {
m.def("add", [](int a, int b) { return a + b; });
}
// old
PYBIND11_PLUGIN(example) {
py::module m("example");
m.def("add", [](int a, int b) { return a + b; });
return m.ptr();
}
* pybind11's headers and build system now more strictly enforce hidden symbol
visibility for extension modules. This should be seamless for most users,
but see the upgrade guide if you use a custom build system.
* Support for ``py::module_local`` types which allow multiple modules to
export the same C++ types without conflicts. This is useful for opaque
types like ``std::vector<int>``. ``py::bind_vector`` and ``py::bind_map``
now default to ``py::module_local`` if their elements are builtins or
local types. See :ref:`module_local` for details.
`#949 <https://github.com/pybind/pybind11/pull/949>`_,
`#981 <https://github.com/pybind/pybind11/pull/981>`_,
`#995 <https://github.com/pybind/pybind11/pull/995>`_,
`#997 <https://github.com/pybind/pybind11/pull/997>`_.
* Custom constructors can now be added very easily using lambdas or factory
functions which return a class instance by value, pointer or holder. This
supersedes the old placement-new ``__init__`` technique.
See :ref:`custom_constructors` for details.
`#805 <https://github.com/pybind/pybind11/pull/997>`_.
.. code-block:: cpp
struct Example {
Example(std::string);
};
py::class_<Example>(m, "Example")
.def(py::init<std::string>()) // existing constructor
.def(py::init([](int n) { // custom constructor
return std::make_unique<Example>(std::to_string(n));
}));
* Builtin support for converting C++17 standard library types and general
conversion improvements:
1. C++17 ``std::variant`` is supported right out of the box. C++11/14
equivalents (e.g. ``boost::variant``) can also be added with a simple
user-defined specialization. See :ref:`cpp17_container_casters` for details.
`#811 <https://github.com/pybind/pybind11/pull/811>`_,
`#845 <https://github.com/pybind/pybind11/pull/845>`_,
`#989 <https://github.com/pybind/pybind11/pull/989>`_.
2. Out-of-the-box support for C++17 ``std::string_view``.
`#906 <https://github.com/pybind/pybind11/pull/906>`_.
3. Improved compatibility of the builtin ``optional`` converter.
`#874 <https://github.com/pybind/pybind11/pull/874>`_.
4. The ``bool`` converter now accepts ``numpy.bool_`` and types which
define ``__bool__`` (Python 3.x) or ``__nonzero__`` (Python 2.7).
`#925 <https://github.com/pybind/pybind11/pull/925>`_.
5. C++-to-Python casters are now more efficient and move elements out
of rvalue containers whenever possible.
`#851 <https://github.com/pybind/pybind11/pull/851>`_,
`#936 <https://github.com/pybind/pybind11/pull/936>`_,
`#938 <https://github.com/pybind/pybind11/pull/938>`_.
6. Fixed ``bytes`` to ``std::string/char*`` conversion on Python 3.
`#817 <https://github.com/pybind/pybind11/pull/817>`_.
7. Fixed lifetime of temporary C++ objects created in Python-to-C++ conversions.
`#924 <https://github.com/pybind/pybind11/pull/924>`_.
* Scope guard call policy for RAII types, e.g. ``py::call_guard<py::gil_scoped_release>()``.
See :ref:`call_policies` for details.
`#740 <https://github.com/pybind/pybind11/pull/740>`_.
* Improved handling of types and exceptions across module boundaries.
`#915 <https://github.com/pybind/pybind11/pull/915>`_,
`#951 <https://github.com/pybind/pybind11/pull/951>`_,
`#995 <https://github.com/pybind/pybind11/pull/995>`_.
* Fixed destruction order of ``py::keep_alive`` nurse/patient objects
in reference cycles.
`#856 <https://github.com/pybind/pybind11/pull/856>`_.
* Numpy and buffer protocol related improvements:
1. Support for negative strides in Python buffer objects/numpy arrays. This
required changing integers from unsigned to signed for the related C++ APIs.
Note: If you have compiler warnings enabled, you may notice some new conversion
warnings after upgrading. These can be resolved with ``static_cast``.
`#782 <https://github.com/pybind/pybind11/pull/782>`_.
2. Support ``std::complex`` and arrays inside ``PYBIND11_NUMPY_DTYPE``.
`#831 <https://github.com/pybind/pybind11/pull/831>`_,
`#832 <https://github.com/pybind/pybind11/pull/832>`_.
3. Support for constructing ``py::buffer_info`` and ``py::arrays`` using
arbitrary containers or iterators instead of requiring a ``std::vector``.
`#788 <https://github.com/pybind/pybind11/pull/788>`_,
`#822 <https://github.com/pybind/pybind11/pull/822>`_,
`#860 <https://github.com/pybind/pybind11/pull/860>`_.
4. Explicitly check numpy version and require >= 1.7.0.
`#819 <https://github.com/pybind/pybind11/pull/819>`_.
* Support for allowing/prohibiting ``None`` for specific arguments and improved
``None`` overload resolution order. See :ref:`none_arguments` for details.
`#843 <https://github.com/pybind/pybind11/pull/843>`_.
`#859 <https://github.com/pybind/pybind11/pull/859>`_.
* Added ``py::exec()`` as a shortcut for ``py::eval<py::eval_statements>()``
and support for C++11 raw string literals as input. See :ref:`eval`.
`#766 <https://github.com/pybind/pybind11/pull/766>`_,
`#827 <https://github.com/pybind/pybind11/pull/827>`_.
* ``py::vectorize()`` ignores non-vectorizable arguments and supports
member functions.
`#762 <https://github.com/pybind/pybind11/pull/762>`_.
* Support for bound methods as callbacks (``pybind11/functional.h``).
`#815 <https://github.com/pybind/pybind11/pull/815>`_.
* Allow aliasing pybind11 methods: ``cls.attr("foo") = cls.attr("bar")``.
`#802 <https://github.com/pybind/pybind11/pull/802>`_.
* Don't allow mixed static/non-static overloads.
`#804 <https://github.com/pybind/pybind11/pull/804>`_.
* Fixed overriding static properties in derived classes.
`#784 <https://github.com/pybind/pybind11/pull/784>`_.
* Improved deduction of member function of derived class when the bases
isn't registered with pybind11.
`#855 <https://github.com/pybind/pybind11/pull/855>`_.
.. code-block:: cpp
struct Base {
int foo() { return 42; }
}
struct Derived : Base {}
// Now works, but previously required also binding `Base`
py::class_<Derived>(m, "Derived")
.def("foo", &Derived::foo); // function is actually from `Base`
* Fixed issues with multiple inheritance with offset base/derived pointers.
`#812 <https://github.com/pybind/pybind11/pull/812>`_,
`#866 <https://github.com/pybind/pybind11/pull/866>`_,
`#960 <https://github.com/pybind/pybind11/pull/960>`_.
* Improved support for the ``/std:c++14`` and ``/std:c++latest`` modes
on MSVC 2017.
`#841 <https://github.com/pybind/pybind11/pull/841>`_,
`#999 <https://github.com/pybind/pybind11/pull/999>`_.
* Fixed detection of private operator new on MSVC.
`#893 <https://github.com/pybind/pybind11/pull/893>`_,
`#918 <https://github.com/pybind/pybind11/pull/918>`_.
* Intel C++ compiler compatibility fixes.
`#937 <https://github.com/pybind/pybind11/pull/937>`_.
* Fixed implicit conversion of `py::enum_` to integer types on Python 2.7.
`#821 <https://github.com/pybind/pybind11/pull/821>`_.
* Fixed ``__truediv__`` on Python 2 and ``__itruediv__`` on Python 3.
`#867 <https://github.com/pybind/pybind11/pull/867>`_.
* ``py::capsule`` objects now support the ``name`` attribute. This is useful
for interfacing with ``scipy.LowLevelCallable``.
`#902 <https://github.com/pybind/pybind11/pull/902>`_.
* Fixed ``py::make_iterator``'s ``__next__()`` for past-the-end calls.
`#897 <https://github.com/pybind/pybind11/pull/897>`_.
* Added ``error_already_set::matches()`` for checking Python exceptions.
`#772 <https://github.com/pybind/pybind11/pull/772>`_.
* Deprecated ``py::error_already_set::clear()``. It's no longer needed
following a simplification of the ``py::error_already_set`` class.
`#954 <https://github.com/pybind/pybind11/pull/954>`_.
* Deprecated ``py::handle::operator==()`` in favor of ``py::handle::is()``
`#825 <https://github.com/pybind/pybind11/pull/825>`_.
* Deprecated ``py::object::borrowed``/``py::object::stolen``.
Use ``py::object::borrowed_t{}``/``py::object::stolen_t{}`` instead.
`#771 <https://github.com/pybind/pybind11/pull/771>`_.
* Additional compile-time and run-time error checking and more informative messages.
