Binding classes with template parameters
|
||||
========================================
|
||||
|
||||
pybind11 can also wrap classes that have template parameters. Consider these classes:
|
||||
|
||||
.. code-block:: cpp
|
||||
|
||||
struct Cat {};
|
||||
struct Dog {};
|
||||
|
||||
template <typename PetType>
|
||||
struct Cage {
|
||||
Cage(PetType& pet);
|
||||
PetType& get();
|
||||
};
|
||||
|
||||
C++ templates may only be instantiated at compile time, so pybind11 can only
|
||||
wrap instantiated templated classes. You cannot wrap a non-instantiated template:
|
||||
|
||||
.. code-block:: cpp
|
||||
|
||||
// BROKEN (this will not compile)
|
||||
py::class_<Cage>(m, "Cage");
|
||||
.def("get", &Cage::get);
|
||||
|
||||
You must explicitly specify each template/type combination that you want to
|
||||
wrap separately.
|
||||
|
||||
.. code-block:: cpp
|
||||
|
||||
// ok
|
||||
py::class_<Cage<Cat>>(m, "CatCage")
|
||||
.def("get", &Cage<Cat>::get);
|
||||
|
||||
// ok
|
||||
py::class_<Cage<Dog>>(m, "DogCage")
|
||||
.def("get", &Cage<Dog>::get);
|
||||
|
||||
If your class methods have template parameters you can wrap those as well,
|
||||
but once again each instantiation must be explicitly specified:
|
||||
|
||||
.. code-block:: cpp
|
||||
|
||||

Local vs Global Exception Translators
|
||||
=====================================
|
||||
|
||||
When a global exception translator is registered, it will be applied across all
|
||||
modules in the reverse order of registration. This can create behavior where the
|
||||
order of module import influences how exceptions are translated.
|
||||
|
||||
If module1 has the following translator:
|
||||
|
||||
.. code-block:: cpp
|
||||
|
||||
py::register_exception_translator([](std::exception_ptr p) {
|
||||
try {
|
||||
if (p) std::rethrow_exception(p);
|
||||
} catch (const std::invalid_argument &e) {
|
||||
PyErr_SetString("module1 handled this")
|
||||
}
|
||||
}
|
||||
|
||||
and module2 has the following similar translator:
|
||||
|
||||
.. code-block:: cpp
|
||||
|
||||
py::register_exception_translator([](std::exception_ptr p) {
|
||||
try {
|
||||
if (p) std::rethrow_exception(p);
|
||||
} catch (const std::invalid_argument &e) {
|
||||
PyErr_SetString("module2 handled this")
|
||||
}
|
||||
}
|
||||
|
||||
then which translator handles the invalid_argument will be determined by the
|
||||
order that module1 and module2 are imported. Since exception translators are
|
||||
applied in the reverse order of registration, which ever module was imported
|
||||
last will "win" and that translator will be applied.
|
||||
|
||||
If there are multiple pybind11 modules that share exception types (either
|
||||
standard built-in or custom) loaded into a single python instance and
|
||||
consistent error handling behavior is needed, then local translators should be
|
||||
used.
|
||||
|
||||
Changing the previous example to use ``register_local_exception_translator``
|
||||
would mean that when invalid_argument is thrown in the module2 code, the
|
||||
module2 translator will always handle it, while in module1, the module1
|
||||
translator will do the same.

Chaining exceptions ('raise from')

==================================

In Python 3.3 a mechanism for indicating that exceptions were caused by other

exceptions was introduced:

To do a similar thing in pybind11, you can use the ``py::raise_from`` function. It
|

sets the current python error indicator, so to continue propagating the exception
|
||||
you should ``throw py::error_already_set()`` (Python 3 only).

Binding functions with template parameters

You can bind functions that have template parameters. Here's a function:

.. code-block:: cpp
|
||||
|
||||
template <typename T>
|
||||
void set(T t);
|

non-instantiated function:

.. code-block:: cpp
|

|
||||
// BROKEN (this will not compile)
|
||||
m.def("set", &set);
|
||||
|

You must bind each instantiated function template separately. You may bind

each instantiation with the same name, which will be treated the same as
|
||||
an overloaded function:
|
||||
|

.. code-block:: cpp

--------------

|
||||
Removed support for Python 2.7, Python 3.5, and MSVC 2015. Support for MSVC
|
||||
2017 is limited due to availability of CI runners; we highly recommend MSVC
|
||||
2019 or 2022 be used.
|
||||
|
||||
New features:
|
||||
|
||||
* ``type_caster<std::monostate>`` was added. ``std::monostate`` is a tag type
|
||||
that allows ``std::variant`` to act as an optional, or allows default
|
||||
construction of a ``std::variant`` holding a non-default constructible type.

Version 2.9.1 (Feb 2, 2022)
|
||||
---------------------------
|
||||
|
||||
Changes:
|
||||
|
||||
* If possible, attach Python exception with ``py::raise_from`` to ``TypeError``
|
||||
when casting from C++ to Python. This will give additional info if Python
|
||||
exceptions occur in the caster. Adds a test case of trying to convert a set
|
||||
from C++ to Python when the hash function is not defined in Python.
|
||||
`#3605 <https://github.com/pybind/pybind11/pull/3605>`_
|
||||
|
||||
* Add a mapping of C++11 nested exceptions to their Python exception
|
||||
equivalent using ``py::raise_from``. This attaches the nested exceptions in
|
||||
Python using the ``__cause__`` field.
|
||||
`#3608 <https://github.com/pybind/pybind11/pull/3608>`_
|
||||
|
||||
* Propagate Python exception traceback using ``raise_from`` if a pybind11
|
||||
function runs out of overloads.
|
||||
`#3671 <https://github.com/pybind/pybind11/pull/3671>`_
|
||||
|
||||
* ``py::multiple_inheritance`` is now only needed when C++ bases are hidden
|
||||
from pybind11.
|
||||
`#3650 <https://github.com/pybind/pybind11/pull/3650>`_ and
|
||||
`#3659 <https://github.com/pybind/pybind11/pull/3659>`_
|
||||
|
||||
|
||||
Bug fixes:
|
||||
|
||||
* Remove a boolean cast in ``numpy.h`` that causes MSVC C4800 warnings when
|
||||
compiling against Python 3.10 or newer.
|
||||
`#3669 <https://github.com/pybind/pybind11/pull/3669>`_
|
||||
|
||||
* Render ``py::bool_`` and ``py::float_`` as ``bool`` and ``float``
|
||||
respectively.
|
||||
`#3622 <https://github.com/pybind/pybind11/pull/3622>`_
|
||||
|
||||
Build system improvements:
|
||||
|
||||

|
||||
`#3663 <https://github.com/pybind/pybind11/pull/3663>`_
|
||||
|
||||

|
||||
`#3577 <https://github.com/pybind/pybind11/pull/3577>`_
|
||||
|
||||

|
||||
`#3610 <https://github.com/pybind/pybind11/pull/3610>`_
|
||||
|
||||
* More uniform handling of test targets.
|
||||
`#3590 <https://github.com/pybind/pybind11/pull/3590>`_
|
||||
|
||||
* Add clang-tidy readability check to catch potentially swapped function args.

Version 2.9.0 (Dec 28, 2021)
|
||||
----------------------------
|
||||
|
||||
This is the last version to support Python 2.7 and 3.5.
|
||||
|
||||
New Features:
|
||||
|
||||
* Allow ``py::args`` to be followed by other arguments; the remaining arguments
|
||||
are implicitly keyword-only, as if a ``py::kw_only{}`` annotation had been
|
||||
used.
|
||||
`#3402 <https://github.com/pybind/pybind11/pull/3402>`_
|

Changes:
|
||||
|
||||
* Make str/bytes/memoryview more interoperable with ``std::string_view``.
|
||||
`#3521 <https://github.com/pybind/pybind11/pull/3521>`_
|
||||
|
||||
* Replace ``_`` with ``const_name`` in internals, avoid defining ``pybind::_``
|
||||
if ``_`` defined as macro (common gettext usage)
|
||||
`#3423 <https://github.com/pybind/pybind11/pull/3423>`_
|
||||
|
||||
|
||||
Bug fixes:
|
||||
|
||||
* Fix a rare warning about extra copy in an Eigen constructor.
|
||||
`#3486 <https://github.com/pybind/pybind11/pull/3486>`_
|
||||
|
||||
* Fix caching of the C++ overrides.
|
||||
`#3465 <https://github.com/pybind/pybind11/pull/3465>`_
|
||||
|
||||
* Add missing ``std::forward`` calls to some ``cpp_function`` overloads.
|
||||
`#3443 <https://github.com/pybind/pybind11/pull/3443>`_
|
||||
|
||||
* Support PyPy 7.3.7 and the PyPy3.8 beta. Test python-3.11 on PRs with the
|
||||
``python dev`` label.
|
||||
`#3419 <https://github.com/pybind/pybind11/pull/3419>`_

``Eigen::Map<Eigen::SparseMatrix<...>>`` for Eigen 3.3+.
|
||||
`#3499 <https://github.com/pybind/pybind11/pull/3499>`_
|
||||
|
||||

|
||||
`#3497 <https://github.com/pybind/pybind11/pull/3497>`_
|
||||
|
||||
Build system improvements:
|
||||
|
||||
* Nicer CMake printout and IDE organisation for pybind11's own tests.
|
||||
`#3479 <https://github.com/pybind/pybind11/pull/3479>`_
|
||||
|
||||
* CMake: report version type as part of the version string to avoid a spurious
|
||||
space in the package status message.
|
||||
`#3472 <https://github.com/pybind/pybind11/pull/3472>`_
|
||||
|
||||
* Flags starting with ``-g`` in ``$CFLAGS`` and ``$CPPFLAGS`` are no longer
|
||||
overridden by ``.Pybind11Extension``.
|
||||
`#3436 <https://github.com/pybind/pybind11/pull/3436>`_
|
||||
|
||||
* Ensure ThreadPool is closed in ``setup_helpers``.
|
||||
`#3548 <https://github.com/pybind/pybind11/pull/3548>`_
|
||||
|
||||
* Avoid LTS on ``mips64`` and ``ppc64le`` (reported broken).
|
||||
`#3557 <https://github.com/pybind/pybind11/pull/3557>`_
|
||||
|
||||
|
||||
v2.8.1 (Oct 27, 2021)
|
||||
---------------------
|
||||
|
||||
Changes and additions:
|
||||
|
||||
* The simple namespace creation shortcut added in 2.8.0 was deprecated due to
|
||||
usage of CPython internal API, and will be removed soon. Use
|
||||
``py::module_::import("types").attr("SimpleNamespace")``.
|
||||
`#3374 <https://github.com/pybinyyd/pybind11/pull/3374>`_
|
||||
|
||||
* Add C++ Exception type to throw and catch ``AttributeError``. Useful for
|
||||
defining custom ``__setattr__`` and ``__getattr__`` methods.
|
||||
`#3387 <https://github.com/pybind/pybind11/pull/3387>`_
|
||||
|
||||
Fixes:
|
||||
|
||||
* Fixed the potential for dangling references when using properties with
|
||||
``std::optional`` types.
|
||||
`#3376 <https://github.com/pybind/pybind11/pull/3376>`_
|
||||
|
||||
* Modernize usage of ``PyCodeObject`` on Python 3.9+ (moving toward support for
|
||||
Python 3.11a1)
|
||||
`#3368 <https://github.com/pybind/pybind11/pull/3368>`_
|
||||
|
||||
* A long-standing bug in ``eigen.h`` was fixed (originally PR #3343). The bug
|
||||
was unmasked by newly added ``static_assert``'s in the Eigen 3.4.0 release.
|
||||
`#3352 <https://github.com/pybind/pybind11/pull/3352>`_
|
||||
|
||||
* Support multiple raw inclusion of CMake helper files (Conan.io does this for
|
||||
multi-config generators).
|
||||
`#3420 <https://github.com/pybind/pybind11/pull/3420>`_
|
||||
|
||||
* Fix harmless warning on upcoming CMake 3.22.
|
||||
`#3368 <https://github.com/pybind/pybind11/pull/3368>`_
|
||||
|
||||
* Fix 2.8.0 regression with MSVC 2017 + C++17 mode + Python 3.
|
||||
`#3407 <https://github.com/pybind/pybind11/pull/3407>`_
|
||||
|
||||
* Fix 2.8.0 regression that caused undefined behavior (typically
|
||||
segfaults) in ``make_key_iterator``/``make_value_iterator`` if dereferencing
|
||||
the iterator returned a temporary value instead of a reference.
|
||||
`#3348 <https://github.com/pybind/pybind11/pull/3348>`_
|
||||
|
||||
|
||||
v2.8.0 (Oct 4, 2021)
|
||||
--------------------
|
||||
|
||||
New features:
|
||||
|
||||
* Added ``py::raise_from`` to enable chaining exceptions.
|
||||
`#3215 <https://github.com/pybind/pybind11/pull/3215>`_
|
||||
|
||||
* Allow exception translators to be optionally registered local to a module
|
||||
instead of applying globally across all pybind11 modules. Use
|
||||
``register_local_exception_translator(ExceptionTranslator&& translator)``
|
||||
instead of ``register_exception_translator(ExceptionTranslator&&
|
||||
translator)`` to keep your exception remapping code local to the module.
|
||||
`#2650 <https://github.com/pybind/pybind11/pull/2650>`_
|
||||
`#2650 <https://github.com/pybinyyd/pybind11/pull/2650>`_
|
||||
|
||||
* Add ``make_simple_namespace`` function for instantiating Python
|
||||
``SimpleNamespace`` objects. **Deprecated in 2.8.1.**
|
||||
`#2840 <https://github.com/pybind/pybind11/pull/2840>`_
|
||||
|
||||
* ``pybind11::scoped_interpreter`` and ``initialize_interpreter`` have new
|
||||
arguments to allow ``sys.argv`` initialization.
|
||||
`#2341 <https://github.com/pybind/pybind11/pull/2341>`_
|
||||
|
||||
* Allow Python builtins to be used as callbacks in CPython.
|
||||
`#1413 <https://github.com/pybind/pybind11/pull/1413>`_
|
||||
|
||||
* Added ``view`` to view arrays with a different datatype.
|
||||
`#987 <https://github.com/pybind/pybind11/pull/987>`_
|
||||
|
||||
* Implemented ``reshape`` on arrays.
|
||||
`#984 <https://github.com/pybind/pybind11/pull/984>`_
|
||||
|
||||
* Enable defining custom ``__new__`` methods on classes by fixing bug
|
||||
preventing overriding methods if they have non-pybind11 siblings.
|
||||
`#3265 <https://github.com/pybind/pybind11/pull/3265>`_
|
||||
|
||||
* Add ``make_value_iterator()``, and fix ``make_key_iterator()`` to return
|
||||
references instead of copies.
|
||||
`#3293 <https://github.com/pybind/pybind11/pull/3293>`_
|
||||
|
||||
* Improve the classes generated by ``bind_map``: `#3310 <https://github.com/pybind/pybind11/pull/3310>`_
|
||||
|
||||
* Change ``.items`` from an iterator to a dictionary view.
|
||||
* Add ``.keys`` and ``.values`` (both dictionary views).
|
||||
* Allow ``__contains__`` to take any object.
|
||||
|
||||
* ``pybind11::custom_type_setup`` was added, for customizing the
|
||||
``PyHeapTypeObject`` corresponding to a class, which may be useful for
|
||||
enabling garbage collection support, among other things.
|
||||
`#3287 <https://github.com/pybind/pybind11/pull/3287>`_
|
||||
|
||||
|
||||
Changes:
|
||||
|
||||
* Set ``__file__`` constant when running ``eval_file`` in an embedded interpreter.
|
||||
`#3233 <https://github.com/pybind/pybind11/pull/3233>`_
|
||||
|
||||
* Python objects and (C++17) ``std::optional`` now accepted in ``py::slice``
|
||||
constructor.
|
||||
`#1101 <https://github.com/pybind/pybind11/pull/1101>`_
|
||||
|
||||
* The pybind11 proxy types ``str``, ``bytes``, ``bytearray``, ``tuple``,
|
||||
``list`` now consistently support passing ``ssize_t`` values for sizes and
|
||||
indexes. Previously, only ``size_t`` was accepted in several interfaces.
|
||||
`#3219 <https://github.com/pybind/pybind11/pull/3219>`_
|
||||
|
||||
* Avoid evaluating ``PYBIND11_TLS_REPLACE_VALUE`` arguments more than once.
|
||||
`#3290 <https://github.com/pybind/pybind11/pull/3290>`_
|
||||
|
||||
Fixes:
|
||||
|
||||
* Bug fix: enum value's ``__int__`` returning non-int when underlying type is
|
||||
bool or of char type.
|
||||
`#1334 <https://github.com/pybind/pybind11/pull/1334>`_
|
||||
|
||||
* Fixes bug in setting error state in Capsule's pointer methods.
|
||||
`#3261 <https://github.com/pybind/pybind11/pull/3261>`_
|
||||
|
||||
* A long-standing memory leak in ``py::cpp_function::initialize`` was fixed.
|
||||
`#3229 <https://github.com/pybind/pybind11/pull/3229>`_
|
||||
|
||||
* Fixes thread safety for some ``pybind11::type_caster`` which require lifetime
|
||||
extension, such as for ``std::string_view``.
|
||||
`#3237 <https://github.com/pybind/pybind11/pull/3237>`_
|
||||
|
||||
* Restore compatibility with gcc 4.8.4 as distributed by ubuntu-trusty, linuxmint-17.
|
||||
`#3270 <https://github.com/pybind/pybind11/pull/3270>`_
|
||||
|
||||
|
||||
Build system improvements:
|
||||
|
||||
* Fix regression in CMake Python package config: improper use of absolute path.
|
||||
`#3144 <https://github.com/pybind/pybind11/pull/3144>`_
|
||||
|
||||
* Cached Python version information could become stale when CMake was re-run
|
||||
with a different Python version. The build system now detects this and
|
||||
updates this information.
|
||||
`#3299 <https://github.com/pybind/pybind11/pull/3299>`_
|
||||
|
||||
* Specified UTF8-encoding in setup.py calls of open().
|
||||
`#3137 <https://github.com/pybind/pybind11/pull/3137>`_
|
||||
|
||||
* Fix a harmless warning from CMake 3.21 with the classic Python discovery.
|
||||
`#3220 <https://github.com/pybind/pybind11/pull/3220>`_
|
||||
|
||||
* Eigen repo and version can now be specified as cmake options.
|
||||
`#3324 <https://github.com/pybind/pybind11/pull/3324>`_
|
||||
|
||||
|
||||
Backend and tidying up:
|
||||
|
||||
* Reduced thread-local storage required for keeping alive temporary data for
|
||||
type conversion to one key per ABI version, rather than one key per extension
|
||||
module. This makes the total thread-local storage required by pybind11 2
|
||||
keys per ABI version.
|
||||
`#3275 <https://github.com/pybind/pybind11/pull/3275>`_
|
||||
|
||||
* Optimize NumPy array construction with additional moves.
|
||||
`#3183 <https://github.com/pybind/pybind11/pull/3183>`_
|
||||
|
||||
* Conversion to ``std::string`` and ``std::string_view`` now avoids making an
|
||||
extra copy of the data on Python >= 3.3.
|
||||
`#3257 <https://github.com/pybind/pybind11/pull/3257>`_
|
||||
|
||||
* Remove const modifier from certain C++ methods on Python collections
|
||||
(``list``, ``set``, ``dict``) such as (``clear()``, ``append()``,
|
||||
``insert()``, etc...) and annotated them with ``py-non-const``.
|
||||
|
||||
* Enable readability ``clang-tidy-const-return`` and remove useless consts.
|
||||
`#3254 <https://github.com/pybind/pybind11/pull/3254>`_
|
||||
`#3194 <https://github.com/pybind/pybind11/pull/3194>`_
|
||||
|
||||
* The clang-tidy ``google-explicit-constructor`` option was enabled.
|
||||
`#3250 <https://github.com/pybind/pybind11/pull/3250>`_
|
||||
|
||||
* Mark a pytype move constructor as noexcept (perf).
|
||||
`#3236 <https://github.com/pybind/pybind11/pull/3236>`_
|
||||
|
||||
* Enable clang-tidy check to guard against inheritance slicing.
|
||||
`#3210 <https://github.com/pybind/pybind11/pull/3210>`_
|
||||
|
||||
* Legacy warning suppression pragma were removed from eigen.h. On Unix
|
||||
platforms, please use -isystem for Eigen include directories, to suppress
|
||||
compiler warnings originating from Eigen headers. Note that CMake does this
|
||||
by default. No adjustments are needed for Windows.
|
||||
`#3198 <https://github.com/pybind/pybind11/pull/3198>`_
|
||||
|
||||
* Format pybind11 with isort consistent ordering of imports
|
||||
`#3195 <https://github.com/pybind/pybind11/pull/3195>`_
|
||||
|
||||
* The warnings-suppression "pragma clamp" at the top/bottom of pybind11 was
|
||||
removed, clearing the path to refactoring and IWYU cleanup.
|
||||
`#3186 <https://github.com/pybind/pybind11/pull/3186>`_
|
||||
|
||||
* Enable most bugprone checks in clang-tidy and fix the found potential bugs
|
||||
and poor coding styles.
|
||||
`#3166 <https://github.com/pybind/pybind11/pull/3166>`_
|
||||
|
||||
* Add ``clang-tidy-readability`` rules to make boolean casts explicit improving
|
||||
code readability. Also enabled other misc and readability clang-tidy checks.
|
||||
`#3148 <https://github.com/pybind/pybind11/pull/3148>`_
|
