-2 New, Changed or Resolved Features
-=====================================
-
-
-
-2.1 Breaking API
-==================
-
-
-    Receiver
+    Firmware
    --------


-    *   Receiver callbacks
-        Brought much more metadata to receiver callbacks to construct the image.
-        Update MultiReceiverApp to reflect this change.
-
-
-    *   File path
-        At start of acquisition or at rx_start command, the file path is only 
-        then verified if it exists and created if it does not.
+    *   [Eiger] Blocking trigger on quad
+        Previously, blocking software trigger on a quad was not blocking. Fixed
+        with firmware v32.


    Client
    ------


-    *   Removed receiver/publisher ZMQ IP
-        Command line: rx_zmqip gives a warning and does nothing
-        Python : rx_zmqip removed
-        C++ API: get/setRxZmqIP removed
-
-        Publisher zmq IP set to '0.0.0.0' or to listen on all interfaces.
-        The publisher will determine which interface to stream out from based on
-        the network route to the subscriber IP. Hence, receiver zmq IP is not 
-        required.
+    *   Limit port number max to 65535
+        Previously, one could set the port numbers (TCP, UDP, ZMQ) to values 
+        higher than 65535 and also to 0. However, it was truncated to 16 bit
+        in the background, but not relayed to the user. 
+        Now, it will throw if it is 0 or greater than 65535 (16 bit).


-    *   Write register, Set or Clear bit
-        Validation for this advanced feature has been removed by default. 
-        One can force validation by using --validate in the command line or by 
-        setting the validate option in the API.
-       
-
-    ZMQ
-    ---
+    *   Stopping acqusition for a single or subset of modules
+        The Detector API previously stopped all modules.
+        Now, it takes into account which modules the user wanted to stop.


-    *   Publisher socket constructor does not take an IP anymore.
-        The details are above under 'Removed receiver/publisher ZMQ IP'.
+    *   [Jungfrau] Stop in sync mode
+        When stopping acquisition in sync mode, only the master module sometimes 
+        returns 'Idle' state instead of 'Stopped'. The software threw an 
+        exception for the different states then.
+        Now, it does not throw and a fix will be added to the next firmware 
+        release for the different states (with SW release: v8.0.0).


-    GUI/ Client Callback
+    *   [Eiger] Incorrect error message in Stop
+        When stopping acquisition, if a half module were to give an error in a 
+        rare case while the others succeeded, this would result in an re-attempt 
+        to stop 9 more times before throwing an incorrect exception messsage that 
+        it could not stop.
+        Now, it is handled and will throw an exception of the error status
+        immediately.
+
+
+    Receiver
+    --------
+
+
+    *   Limit TCP port number (command line) to max of 65535
+        Refer issue under 'Client'.
+
+    
+    Detector Simulator
+    ------------------
+
+
+    *   Limit TCP port number (command line) to max of 65535
+        Refer issue under 'Client'.
+
+
+    *   Some commands such as 'readnrows' would complain that it cannot be set 
+        because the detector is not idle, but was setting it anyway. Fixed.
+
+
+    Gui/ Client Callback
    --------------------


-    *   completeImage member in detectorData attribute now returns false only
-        if any the sub images (from different udp ports) have completeImage
-        set to false in the JSON header. This is set if therea are any missing 
-        packets for that udp port on slsReceiver/slsMultiReceiver. 
-        
-        The different subimages are anyway not synchronized. This errs when
-        there are different missing images across multiple UDP ports. 
-
-        The Gui does not show "complete image" in the status bar anymore. 
-        If any of the udp ports have missing packets for that current disaplayed 
-        image, then the "missing packets" will show in red in the status bar.
+    *   [Jungfrau] Gui: corrected color map of gain plot
+        Previously, color on the gain plot did not update after the first image, 
+        unless there were x/y min/max changes or window resizing. Fixed.


-    Detector Server
+    *   [Jungfrau] Acquisition finished callback error status in sync mode
+        When stopping acquisition in multi module Jungfrau sync mode, 
+        different status (master 'idle' and slaves 'stopped' in 
+        firmware 2.4.1 or 1.4.1) show as 'error' in acquisition finished call 
+        back (mainly used for gui). This is fixed.
+
+
+    *   [Jungfrau] Gui: Next frame number shown as 0 for inconsistency
+        When stopping an acquisition in a multi module Jungfrau, the next 
+        frame numbers might be different, for which the Gui shows an error message
+        but keeps the number as 0. Now, it is fixed to show -1 for inconsistency 
+        and error message shown. So, setting 0 will also prompt an error message
+        that 0 is an invalid input.
+
+
+    Data Processing
    ---------------


-    *   [Mythen3] Only run clock can be set
-        Clock 0 is now the run clock and the only one that can be set. 
-        The others are be read only.
-        This affects the following commands:
-        Command line or python API: clkdiv, clkfreq, clkphase, maxclkphaseshift
-        C++ API: get/setClockDivider, getClockFrequency, get/setClockPhase, 
-        getMaxClockPhaseShift
+    *   [Moench] Segmentation fault with moench03RawDataPrcess
+        Previously, it crashed when nframes > 0. Fixed.


-    *   [Jungfrau] Temperature Control
-        Temperature control is enabled by default at on-board detector server 
-        startup. 
-        As before, the default temperature threshold is 65°C and crossing this
-        value will set a temperature event.
+    *   [Moench] Interpolation issues fixed.


+    *   [Moench] When receiver in discard_partial mode and gets an empty frame,
+        it sends a zmq packet with header and no data. This is handled in post
+        processing as a temporary solution.

-2.2 Resolved or Changed Features
-================================
-
-
-    Compilation
-    -----------
-
-
-    *   cmake_source_dir
-        Fixed compilation error when using python and adding the slsDetectorPackage 
-        as a subfolder due to cmake source directory changing.
-
-
-    Client
-    ------
-
-
-    *   Command line Code Generation
-        The command line parsing code is now generated from a yaml file. This is
-        transparent to the user.
-
-    
-    *   Clearer error message about freeing shared memory.
-
-
-    Detector Server
-    ---------------
-
-
-    *   [Gotthard2] Chip reconfiguration
-
-            -   Powering off/on the chip will now switch off chip configuration 
-                property/ configure the chip every time.
-
-            -   Switching off high voltage from a non zero value will now wait 
-                10s to return for safety reasons.
-
-            -   Powering off the chip requires high voltage to have been 
-                switched off prior.
-
-            -   Acquisition requires chip to have been configured prior.
-
-
-    *   [Gotthard2] Burst mode options restricted
-        Burst mode external and continuous mode internal are not allowed to be set
-        anymore as they are anyway not implemented.
-
-
-    Receiver
-    --------
-
-
-    *   [Gotthard I] fixed header stripping fixing segfault.
-
-
-    *   Error or help message for invalid arguments to slsMultiReceiver.
-
-
-    Simulator
-    ---------
-
-
-    *   Refactored stop server to have better start up.
-
-
-    *   Fixed possible memory leak when taking non blocking acquisitions.
-
-
-    *   [Jungfrau] Valid gain values in data sent out. Previously, 2 was also sent out.
-
-   
-    ZMQ
-    ---
-
-
-    *   Publiser socket constructor
-
-        -   enables keep alive socket options to send heartbeat messages to prevent
-            discarded TCP flows if there is no packet for a longer period.
-
-        -   enables IPv6 interfaces
-
-    *   Prints specific error for ENOENT (endpoint does not exist)
-
-
-
-2.3 New Features
-================
-
-
-    Client
-    ------
-
-
-    *   Auto completion
-        bash_autocomplete.sh or zsh_autocomplete.sh must be sourced from the 
-        main package folder to enable auto completion of commands and arguments 
-        for the command line on that shell.
-
-
-    *   sls_detector
-        New executable that can be used instead of 'sls_detector_get' and 
-        'sls_detector_put' for most commands. It will infer from the number of 
-        arguments, which executable (sls_detector_put or sls_detector_get) to use. 
-        For the rare commands that cannot be inferred from the number of arguments,
-        it will complain accordingly.  
-
-
-    *   [Jungfrau] Timing Info Decoder (Advanced configuration)
-        Command line or python API: timing_info_decoder
-        C++ API: get/setTimingInfoDecoder. Options: SWISSFEL (Default), SHINE
-
-
-    *   [Jungfrau] Collection Mode (Advanced configuration)
-        Command line or python API: collectionmode 
-        C++ API: get/setCollectionMode. Options: ELECTRON, HOLE (Default)
-        If chip v1.1, also configures the chip afterwards. 
-        
-        
-    *   [Gotthard2] Next frame number
-        'Stop' in G2 25um is not synchronous and hence might trigger an extra set
-        of frames in the slave module, resulting in the next acquiistion starting
-        with inconsistent frame numbers between master and slave. Solved by 
-        setting next frame number to the larger value (max + 1) after a stop command. 
-        Requires a firmware update.
-
-        Command line or python API: nextframenumber
-        C++ API: get/setNextFrameNumber
-        Can set/get the starting frame number for the next acquistion.
-
-
-    *   [Mythen3] Readout speed
-        Command line, python API: readoutspeed. Options: full_speed (10MHz), 
-        half_speed (20MHz, default), quarter_speed (40MHz)
-        C++ API: get/setReadoutSpeed
-        Also affect: 
-        Command line, python API: readoutspeedlist
-        C++ API: getReadoutSpeedList
-
-
-    *   Sleep
-        Command line, python/ C++ API:  sleep
-        Client sleeps for required time. Advanced command mainly for firmware
-        developers to use in config files.
-
-
-    *   Xilinx Chip Test Board added

-Binary File Format
-====================
-
-This is the default file format that can be configured using command `fformat <commandline.html#term-fformat-binary-hdf5>`_.
-
-    .. code-block:: bash
-
-        sls_detector_put fformat binary
-
-
-Master File
--------------
-
-* File Name: [fpath]/[fname]_master_[findex].json :ref:`Details here<file name format>`
-
-* It is in json format and created for every acquisition.
-
-* It contains :ref:`attributes<master file attributes>` relevant to the acquisition. This can vary with detector type shown in :ref:`master json file examples <json master file examples>` here.
-
-* It shows the :ref:`**SLS Receiver Header** <sls receiver header format>` format used in data files.
-
-* Enabled/disabled using command `fmaster <commandline.html#term-fmaster-0-1>`_. 
-
-
-Data File
----------
-
-* File Name: [fpath]/[fname]_dx_fy_[findex].raw :ref:`Details here<file name format>`
-
-* It store multiple frames sequentially, with total number of frames determined by `rx_framesperfile <commandline.html#term-rx_framesperfile-n_frames>`_ parameter.
-
-* Each frame includes a :ref:`**sls_receiver_header** <sls receiver header format>` structure, followed by the actual frame data.

-File format
-================================
-
-If `fwrite <commandline.html#term-fwrite-0-1>`_ is enabled, the receiver will write data to files. 
-
-Number of Files
----------------
-
-Every acquisition will create a master file and data files. 
-
-An acquisition can have multiple data files for a single frame. The number of files is determined by the number of UDP ports per module and the number of modules.
-
-    * Every modules has its own receiver process. Every receiver process can have 1 or 2 UDP ports.
-    * Each UDP port will create its own file. Therefore, each receiver can write 1 or 2 files.
-    * So, for example a detector with 4 modules with 2 UDP ports each will create a total of 8 files with file names containing UDP port index **'_d0'** to **'_d7'**.
-
-A new file containing **'_f[file_index]'** in file name is also created when reaching the maximum frames per file. Configured using `rx_framesperfile <commandline.html#term-rx_framesperfile-n_frames>`_.
-
-.. _file name format:
-
-Naming
-------
-| Master File Name: [fpath]/[fname]_master_[findex].[ext]
-
-
-| Data File Name: [fpath]/[fname]_dx_fy_[findex].[ext] 
-
-   * fpath: file path set using command `fpath <commandline.html#term-fpath-path>`_. Default: '/'
-   * fname: file name prefix using command `fname <commandline.html#term-fname-name>`_. Default: "run"
-   * findex: acquisition index using command `findex <commandline.html#term-findex-n_value>`_. Automatically incremented for every acquisition with `sls_detector_acquire <commandline.html#term-acquire>`_ (if `fwrite <commandline.html#term-fwrite-0-1>`_ enabled).
-   * x: unique udp port index. New file per UDP port.
-   * y: file index. New file created after reaching max frames per file.
-   * ext: file extension. Default: "raw"(data file) or "json"(master file)
-
-
-Some file name examples:
-
-    .. code-block:: bash
-
-        # first file
-        path-to-file/run_d0_f0_0.raw
-
-        # first file for second UDP port
-        path-to-file/run_d1_f0_0.raw
-
-        # second file after reaching max frames in first file
-        path-to-file/run_d0_f1_0.raw
-        
-        # second acquisition, first file
-        path-to-file/run_d0_f0_1.raw
-
-
-Formats
--------
-
-There are 2 file formats supported by the receiver:
-
-    * Binary - extension .json (master file) or .raw (data files)
-    * HDF5 - extension .h5
-
-The default is binary. HDF5 can be enabled by compiling the package with HDF5 option enabled. The file format is set using the command `fformat <commandline.html#term-fformat-binary-hdf5>`_.

-
-
-| **Pybind11 for Python**
-| v8.0.0+: 
-|   pybind11 is built
-|   * by default from tar file in repo (libs/pybind/v2.1x.0.tar.gz) 
-|   * or use advanced option SLS_FETCH_PYBIND11_FROM_GITHUB [`link <https://github.com/pybind/pybind11>`__].

-|      * v8.x.x : pybind11 (v2.11.0)
-|
-| v7.x.x:
-|   pybind11 packaged into 'libs/pybind'. No longer a submodule. No need for "recursive" or "submodule update".
-| 
-| Older versions:
-|   pybind11 is a submodule. Must be cloned using "recursive" and updated when switching between versions using the following commands.
-
-.. code-block:: bash
-
-    # Note: Only for v6.x.x versions and older
-
-    # clone using recursive to get pybind11 submodule
-    git clone --recursive https://github.com/slsdetectorgroup/slsDetectorPackage.git
-

+    
+    typedef struct {
+        uint64_t frameNumber;
+        uint32_t expLength;
+        uint32_t packetNumber;

+        sls_bitset packetsMask;        /**< is the packets caught bit mask */
+    };
+
+
+.. note :: 
+
+    | The packetNumber in the SLS Receiver Header will be modified to number of packets caught by receiver for that frame. For eg. Jungfrau will have 128 packets per frame. If it is less, then this is a partial frame due to missing packets.
+    
+    | Furthermore, the bit mask will specify which packets have been received.
+
+
+
+
+File format
+--------------
+
+Master file is in json format.
+
+The file name format is [fpath]/[fname]_dx_fy_[findex].raw, where x is module index and y is file index. **fname** is file name prefix and by default "run". **fpath** is '/' by default.
+
+
+Each acquisition will have an increasing acquisition index or findex (if file write enabled). This can be retrieved by using **findex** command. 
+
+
+Each acquisition can have multiple files (the file index number **y**), with **rx_framesperfile** being the maximum number of frames per file. The default varies for each detector type.
+
+
+Some file name examples:
+
+    .. code-block:: bash
+
+        # first file
+        path-to-file/run_d0_f0_0.raw
+
+        # second file after reaching max frames in first file
+        path-to-file/run_d0_f1_0.raw
+        
+        # second acquisition, first file
+        path-to-file/run_d0_f0_1.raw
+
+
+Each acquisition will create a master file that can be enabled/disabled using **fmaster**. This should have parameters relevant to the acquisition.
+
+
+**Binary file format**
+
+This is the default file format. 
+
+
+Each data file will consist of frames, each consisting of slsReceiver Header followed by data for 1 frame.
+
+
+Master file is of ASCII format and will also include the format of the slsReceiver Header.
+
+
+**HDF5 file formats**
+
+#. Compile the package with HDF5 option enabled
+
+    #. Using cmk script: ./cmk.sh -hj9 -d [path of hdf5 dir]
+
+    #. Enable using cmake **-DCMAKE_INSTALL_PREFIX=/path/to/hdf/installation** and **-DSLS_USE_HDF5=ON**
+
+#. Start Receiver process
+
+#. Load config file
+
+#. Set file format from client or in config file
+    .. code-block:: bash
+
+        sls_detector_put fformat hdf5
+
+
+| For multiple, modules, a virtual file linking all the modules is created. Both the data files and virtual files are linked in the master file.

-| **sls_detector_header** (described in :ref:`the current detector header <detector udp header>`)
-    
-| The **packetNumber** from detector UDP header is modified in **sls_receiver_header** to number of packets caught by receiver for that frame and the bit mask for each packet caught is the **packetsMask**. The packetsMask is a total of 512 bits due to the largest number of packets per frame among our detectors.
-
-| For eg. Jungfrau has 128 packets per frame. If **packetNumeber** is 128, then this frame is complete. If it is 127 or less, it is a partial frame due to missing packets. If one would still like to use it, the **packetsMask** will specify which packet has been received or is missing.

+
+.. start
+
+
+**pybind11** is a lightweight header-only library that exposes C++ types
+in Python and vice versa, mainly to create Python bindings of existing
+C++ code. 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 (3.6+, or PyPy) 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
+`pybind11.readthedocs.io <https://pybind11.readthedocs.io/en/latest>`_.
+A PDF version of the manual is available
+`here <https://pybind11.readthedocs.io/_/downloads/en/latest/pdf/>`_.
+And the source code is always available at
+`github.com/pybind/pybind11 <https://github.com/pybind/pybind11>`_.
+
+
+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 3.6+, and PyPy3 7.3 are supported with an implementation-agnostic
+  interface (pybind11 2.9 was the last version to support Python 2 and 3.5).
+
+- 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. A recent pybind11
+  conversion of PyRosetta, an enormous Boost.Python binding project,
+  `reported <https://graylab.jhu.edu/Sergey/2016.RosettaCon/PyRosetta-4.pdf>`_
+  a binary size reduction of **5.4x** and compile time reduction by
+  **5.8x**.
+
+- Function signatures are precomputed at compile time (using
+  ``constexpr``), leading to smaller binaries.
+
+- With little extra effort, C++ types can be pickled and unpickled
+  similar to regular Python objects.
+
+Supported compilers
+-------------------
+
+1. Clang/LLVM 3.3 or newer (for Apple Xcode's clang, this is 5.0.0 or
+   newer)
+2. GCC 4.8 or newer
+3. Microsoft Visual Studio 2017 or newer
+4. Intel classic C++ compiler 18 or newer (ICC 20.2 tested in CI)
+5. Cygwin/GCC (previously tested on 2.5.1)
+6. NVCC (CUDA 11.0 tested in CI)
+7. NVIDIA PGI (20.9 tested in CI)

+Chrono
+======
+
+When including the additional header file :file:`pybind11/chrono.h` conversions
+from C++11 chrono datatypes to python datetime objects are automatically enabled.
+This header also enables conversions of python floats (often from sources such
+as ``time.monotonic()``, ``time.perf_counter()`` and ``time.process_time()``)
+into durations.
+
+An overview of clocks in C++11
+------------------------------
+
+A point of confusion when using these conversions is the differences between
+clocks provided in C++11. 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.

+Custom type casters
+===================
+
+In very rare cases, applications may require custom type casters that cannot be
+expressed using the abstractions provided by pybind11, thus requiring raw
+Python C API calls. This is fairly advanced usage and should only be pursued by
+experts who are familiar with the intricacies of Python reference counting.
+
+The following snippets demonstrate how this works for a very simple ``inty``
+type that that should be convertible from Python types that provide a
+``__int__(self)`` method.
+
+.. code-block:: cpp
+
+    struct inty { long long_value; };
+
+    void print(inty s) {
+        std::cout << s.long_value << std::endl;
+    }
+
+The following Python snippet demonstrates the intended usage from the Python side:
+
+.. code-block:: python
+
+    class A:
+        def __int__(self):
+            return 123
+
+
+    from example import print
+
+    print(A())
+
+To register the necessary conversion routines, it is necessary to add an
+instantiation of the ``pybind11::detail::type_caster<T>`` template.
+Although this is an implementation detail, adding an instantiation of this
+type is explicitly allowed.
+
+.. code-block:: cpp
+
+    namespace pybind11 { namespace detail {
+        template <> struct type_caster<inty> {
+        public:
+            /**

+             */
+            bool load(handle src, bool) {

+                /* Now try to convert into a C++ int */
+                value.long_value = PyLong_AsLong(tmp);
+                Py_DECREF(tmp);
+                /* Ensure return code was OK (to avoid out-of-range errors etc) */
+                return !(value.long_value == -1 && !PyErr_Occurred());
+            }
+
+            /**

+            static handle cast(inty src, return_value_policy /* policy */, handle /* parent */) {

+.. note::

+
+    When using custom type casters, it's important to declare them consistently

+Eigen
+#####
+
+`Eigen <http://eigen.tuxfamily.org>`_ is C++ header-based library for dense and
+sparse linear algebra. 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<MatrixType>`` 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<const MatrixType>``
+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<MatrixType>`` (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 write code such as the following and have it work as
+expected:
+
+.. code-block:: cpp
+
+    void scale_by_2(Eigen::Ref<Eigen::VectorXd> 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_<MyClass>(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<MatrixType>`` 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<MatrixType>`` to the
+more general ``Eigen::Ref<MatrixType, 0, Eigen::Stride<Eigen::Dynamic,
+Eigen::Dynamic>>`` (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<MatrixType>`` 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<Eigen::MatrixXd> 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<double, Eigen::Dynamic, Eigen::Dynamic, Eigen::RowMajor>;
+    // Use RowMatrixXd instead of MatrixXd
+
+Now bound functions accepting ``Eigen::Ref<RowMatrixXd>`` 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<MatrixXd>`` (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<const MatrixType>`` 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<const MatrixXd> &matrix) { /* ... */ }
+    };
+    float some_function(const Eigen::Ref<const MatrixXf> &big,
+                        const Eigen::Ref<const MatrixXf> &small) {
+        // ...
+    }
+
+    // The associated binding code:
+    using namespace pybind11::literals; // for "arg"_a
+    py::class_<MyClass>(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<MatrixXd>`` 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<double, Dynamic, 5>``: 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<float, Dynamic, 4>``), 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.

+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. Lambda functions come in
+two flavors: stateless lambda function resemble classic function pointers that
+link to an anonymous piece of code, while stateful lambda functions
+additionally depend on captured variables that are stored in an anonymous
+*lambda closure object*.
+
+Here is a simple example of a C++ function that takes an arbitrary function
+(stateful or stateless) with signature ``int -> int`` as an argument and runs
+it with the value 10.
+
+.. code-block:: cpp
+
+    int func_arg(const std::function<int(int)> &f) {
+        return f(10);
+    }
+
+The example below is more involved: it takes a function of signature ``int -> int``
+and returns another function of the same kind. The return value is a stateful
+lambda function, which stores the value ``f`` in the capture object and adds 1 to
+its return value upon execution.
+
+.. code-block:: cpp
+
+    std::function<int(int)> func_ret(const std::function<int(int)> &f) {
+        return [f](int i) {
+            return f(i) + 1;
+        };
+    }
+
+This example demonstrates using python named parameters in C++ callbacks which
+requires using ``py::cpp_function`` as a wrapper. Usage is similar to defining
+methods of classes:
+
+.. code-block:: cpp
+
+    py::cpp_function func_cpp() {
+        return py::cpp_function([](int i) { return i+1; },
+           py::arg("number"));
+    }
+
+After including the extra header file :file:`pybind11/functional.h`, it is almost
+trivial to generate binding code for all of these functions.
+
+.. code-block:: cpp
+
+    #include <pybind11/functional.h>
+
+    PYBIND11_MODULE(example, m) {
+        m.def("func_arg", &func_arg);
+        m.def("func_ret", &func_ret);
+        m.def("func_cpp", &func_cpp);
+    }
+
+The following interactive session shows how to call them from Python.
+
+.. code-block:: pycon
+
+    $ python
+    >>> import example
+    >>> def square(i):
+    ...     return i * i
+    ...
+    >>> example.func_arg(square)
+    100L
+    >>> square_plus_1 = example.func_ret(square)
+    >>> square_plus_1(4)
+    17L
+    >>> plus_1 = func_cpp()
+    >>> plus_1(number=43)
+    44L
+
+.. warning::
+
+    Keep in mind that passing a function from C++ to Python (or vice versa)
+    will instantiate a piece of wrapper code that translates function
+    invocations between the two languages. Naturally, this translation
+    increases the computational cost of each function call somewhat. A
+    problematic situation can arise when a function is copied back and forth
+    between Python and C++ many times in a row, in which case the underlying
+    wrappers will accumulate correspondingly. The resulting long sequence of
+    C++ -> Python -> C++ -> ... roundtrips can significantly decrease
+    performance.
+
+    There is one exception: pybind11 detects case where a stateless function
+    (i.e. a function pointer or a lambda function without captured variables)
+    is passed as an argument to another C++ function exposed in Python. In this
+    case, there is no overhead. Pybind11 will extract the underlying C++
+    function pointer from the wrapped function to sidestep a potential C++ ->
+    Python -> C++ roundtrip. This is demonstrated in :file:`tests/test_callbacks.cpp`.
+
+.. note::
+
+    This functionality is very useful when generating bindings for callbacks in
+    C++ libraries (e.g. GUI libraries, asynchronous networking libraries, etc.).
+
+    The file :file:`tests/test_callbacks.cpp` contains a complete example
+    that demonstrates how to work with callbacks and anonymous functions in
+    more detail.

+Type conversions
+################
+
+Apart from enabling cross-language function calls, a fundamental problem
+that a binding tool like pybind11 must address is to provide access to
+native Python types in C++ and vice versa. There are three fundamentally
+different ways to do this—which approach is preferable for a particular type
+depends on the situation at hand.
+
+1. Use a native C++ type everywhere. In this case, the type must be wrapped
+   using pybind11-generated bindings so that Python can interact with it.
+
+2. Use a native Python type everywhere. It will need to be wrapped so that
+   C++ functions can interact with it.
+
+3. Use a native C++ type on the C++ side and a native Python type on the
+   Python side. pybind11 refers to this as a *type conversion*.
+
+   Type conversions are the most "natural" option in the sense that native
+   (non-wrapped) types are used everywhere. The main downside is that a copy
+   of the data must be made on every Python ↔ C++ transition: this is
+   needed since the C++ and Python versions of the same type generally won't
+   have the same memory layout.
+
+   pybind11 can perform many kinds of conversions automatically. An overview
+   is provided in the table ":ref:`conversion_table`".
+
+The following subsections discuss the differences between these options in more
+detail. The main focus in this section is on type conversions, which represent
+the last case of the above list.

+Overview
+########
+
+.. rubric:: 1. Native type in C++, wrapper in Python
+
+Exposing a custom C++ type using :class:`py::class_` was covered in detail
+in the :doc:`/classes` section. There, the underlying data structure is
+always the original C++ class while the :class:`py::class_` wrapper provides
+a Python interface. Internally, when an object like this is sent from C++ to
+Python, pybind11 will just add the outer wrapper layer over the native C++
+object. Getting it back from Python is just a matter of peeling off the
+wrapper.
+
+.. rubric:: 2. Wrapper in C++, native type in Python
+
+This is the exact opposite situation. Now, we have a type which is native to
+Python, like a ``tuple`` or a ``list``. One way to get this data into C++ is
+with the :class:`py::object` family of wrappers. These are explained in more
+detail in the :doc:`/advanced/pycpp/object` section. We'll just give a quick
+example here:
+
+.. code-block:: cpp
+
+    void print_list(py::list my_list) {
+        for (auto item : my_list)
+            std::cout << item << " ";
+    }
+
+.. code-block:: pycon
+
+    >>> print_list([1, 2, 3])
+    1 2 3
+
+The Python ``list`` is not converted in any way -- it's just wrapped in a C++
+:class:`py::list` class. At its core it's still a Python object. Copying a
+:class:`py::list` will do the usual reference-counting like in Python.
+Returning the object to Python will just remove the thin wrapper.
+
+.. rubric:: 3. Converting between native C++ and Python types
+
+In the previous two cases we had a native type in one language and a wrapper in
+the other. Now, we have native types on both sides and we convert between them.
+
+.. code-block:: cpp
+
+    void print_vector(const std::vector<int> &v) {
+        for (auto item : v)
+            std::cout << item << "\n";
+    }
+
+.. code-block:: pycon
+
+    >>> print_vector([1, 2, 3])
+    1 2 3
+
+In this case, pybind11 will construct a new ``std::vector<int>`` and copy each
+element from the Python ``list``. The newly constructed object will be passed
+to ``print_vector``. The same thing happens in the other direction: a new
+``list`` is made to match the value returned from C++.
+
+Lots of these conversions are supported out of the box, as shown in the table
+below. They are very convenient, but keep in mind that these conversions are
+fundamentally based on copying data. This is perfectly fine for small immutable
+types but it may become quite expensive for large data structures. This can be
+avoided by overriding the automatic conversion with a custom wrapper (i.e. the
+above-mentioned approach 1). This requires some manual effort and more details
+are available in the :ref:`opaque` section.

+STL containers
+##############
+
+Automatic conversion
+====================
+
+When including the additional header file :file:`pybind11/stl.h`, conversions
+between ``std::vector<>``/``std::deque<>``/``std::list<>``/``std::array<>``/``std::valarray<>``,
+``std::set<>``/``std::unordered_set<>``, and
+``std::map<>``/``std::unordered_map<>`` and the Python ``list``, ``set`` and
+``dict`` data structures are automatically enabled. The types ``std::pair<>``
+and ``std::tuple<>`` are already supported out of the box with just the core
+:file:`pybind11/pybind11.h` header.
+
+The major downside of these implicit conversions is that containers must be
+converted (i.e. copied) on every Python->C++ and C++->Python transition, which
+can have implications on the program semantics and performance. Please read the
+next sections for more details and alternative approaches that avoid this.
+
+.. note::
+
+    Arbitrary nesting of any of these types is possible.
+
+.. seealso::
+
+    The file :file:`tests/test_stl.cpp` contains a complete
+    example that demonstrates how to pass STL data types in more detail.
+
+.. _cpp17_container_casters:
+
+C++17 library containers
+========================
+
+The :file:`pybind11/stl.h` header also includes support for ``std::optional<>``
+and ``std::variant<>``. 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 <typename T>
+        struct type_caster<boost::optional<T>> : optional_caster<boost::optional<T>> {};
+    }}
+
+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 <typename... Ts>
+        struct type_caster<boost::variant<Ts...>> : variant_caster<boost::variant<Ts...>> {};
+
+        // Specifies the function used to visit the variant -- `apply_visitor` instead of `visit`
+        template <>
+        struct visit_helper<boost::variant> {
+            template <typename... Args>
+            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.
+
+.. warning::
+
+    When converting a ``variant`` type, pybind11 follows the same rules as when
+    determining which function overload to call (:ref:`overload_resolution`), and
+    so the same caveats hold. In particular, the order in which the ``variant``'s
+    alternatives are listed is important, since pybind11 will try conversions in
+    this order. This means that, for example, when converting ``variant<int, bool>``,
+    the ``bool`` variant will never be selected, as any Python ``bool`` is already
+    an ``int`` and is convertible to a C++ ``int``. Changing the order of alternatives
+    (and using ``variant<bool, int>``, in this example) provides a solution.
+
+.. note::
+
+    pybind11 only supports the modern implementation of ``boost::variant``
+    which makes use of variadic templates. This requires Boost 1.56 or newer.
+
+.. _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<int> &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<int> contents;
+    };
+
+    /* ... binding code ... */
+
+    py::class_<MyClass>(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<int>`` into an opaque type, add
+the declaration
+
+.. code-block:: cpp
+
+    PYBIND11_MAKE_OPAQUE(std::vector<int>);
+
+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 adds a template instantiation of ``type_caster``. 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<int>``. 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_<std::vector<int>>(m, "IntVector")
+        .def(py::init<>())
+        .def("clear", &std::vector<int>::clear)
+        .def("pop_back", &std::vector<int>::pop_back)
+        .def("__len__", [](const std::vector<int> &v) { return v.size(); })
+        .def("__iter__", [](std::vector<int> &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/stl_bind.h>
+
+    PYBIND11_MAKE_OPAQUE(std::vector<int>);
+    PYBIND11_MAKE_OPAQUE(std::map<std::string, double>);
+
+    // ...
+
+    // later in binding code:
+    py::bind_vector<std::vector<int>>(m, "VectorInt");
+    py::bind_map<std::map<std::string, double>>(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<int>`` 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<std::vector<int>>(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<int>`` in the above example).
+
+See :ref:`module_local` for more details on module-local bindings.
+

+Strings, bytes and Unicode conversions
+######################################
+
+Passing Python strings to C++
+=============================
+
+When a Python ``str`` is passed from Python to a C++ function that accepts
+``std::string`` or ``char *`` as arguments, pybind11 will encode the Python
+string to UTF-8. All Python ``str`` can be encoded in UTF-8, so this operation
+does not fail.
+
+The C++ language is encoding agnostic. It is the responsibility of the
+programmer to track encodings. It's often easiest to simply `use UTF-8
+everywhere <http://utf8everywhere.org/>`_.
+
+.. code-block:: c++
+
+    m.def("utf8_test",
+        [](const std::string &s) {
+            cout << "utf-8 is icing on the cake.\n";
+            cout << s;
+        }
+    );
+    m.def("utf8_charptr",
+        [](const char *s) {
+            cout << "My favorite food is\n";
+            cout << s;
+        }
+    );
+
+.. code-block:: pycon
+
+    >>> utf8_test("🎂")
+    utf-8 is icing on the cake.
+    🎂
+
+    >>> utf8_charptr("🍕")
+    My favorite food is
+    🍕
+
+.. note::
+
+    Some terminal emulators do not support UTF-8 or emoji fonts and may not
+    display the example above correctly.
+
+The results are the same whether the C++ function accepts arguments by value or
+reference, and whether or not ``const`` is used.
+
+Passing bytes to C++
+--------------------
+
+A Python ``bytes`` object will be passed to C++ functions that accept
+``std::string`` or ``char*`` *without* conversion.  In order to make a function
+*only* accept ``bytes`` (and not ``str``), declare it as taking a ``py::bytes``
+argument.
+
+
+Returning C++ strings to Python
+===============================
+
+When a C++ function returns a ``std::string`` or ``char*`` to a Python caller,
+**pybind11 will assume that the string is valid UTF-8** and will decode it to a
+native Python ``str``, using the same API as Python uses to perform
+``bytes.decode('utf-8')``. If this implicit conversion fails, pybind11 will
+raise a ``UnicodeDecodeError``.
+
+.. code-block:: c++
+
+    m.def("std_string_return",
+        []() {
+            return std::string("This string needs to be UTF-8 encoded");
+        }
+    );
+
+.. code-block:: pycon
+
+    >>> isinstance(example.std_string_return(), str)
+    True
+
+
+Because UTF-8 is inclusive of pure ASCII, there is never any issue with
+returning a pure ASCII string to Python. If there is any possibility that the
+string is not pure ASCII, it is necessary to ensure the encoding is valid
+UTF-8.
+
+.. warning::
+
+    Implicit conversion assumes that a returned ``char *`` is null-terminated.
+    If there is no null terminator a buffer overrun will occur.
+
+Explicit conversions
+--------------------
+
+If some C++ code constructs a ``std::string`` that is not a UTF-8 string, one
+can perform a explicit conversion and return a ``py::str`` object. Explicit
+conversion has the same overhead as implicit conversion.
+
+.. code-block:: c++
+
+    // This uses the Python C API to convert Latin-1 to Unicode
+    m.def("str_output",
+        []() {
+            std::string s = "Send your r\xe9sum\xe9 to Alice in HR"; // Latin-1
+            py::str py_s = PyUnicode_DecodeLatin1(s.data(), s.length());
+            return py_s;
+        }
+    );
+
+.. code-block:: pycon
+
+    >>> str_output()
+    'Send your résumé to Alice in HR'
+
+The `Python C API
+<https://docs.python.org/3/c-api/unicode.html#built-in-codecs>`_ provides
+several built-in codecs.
+
+
+One could also use a third party encoding library such as libiconv to transcode
+to UTF-8.
+
+Return C++ strings without conversion
+-------------------------------------
+
+If the data in a C++ ``std::string`` does not represent text and should be
+returned to Python as ``bytes``, then one can return the data as a
+``py::bytes`` object.
+
+.. code-block:: c++
+
+    m.def("return_bytes",
+        []() {
+            std::string s("\xba\xd0\xba\xd0");  // Not valid UTF-8
+            return py::bytes(s);  // Return the data without transcoding
+        }
+    );
+
+.. code-block:: pycon
+
+    >>> example.return_bytes()
+    b'\xba\xd0\xba\xd0'
+
+
+Note the asymmetry: pybind11 will convert ``bytes`` to ``std::string`` without
+encoding, but cannot convert ``std::string`` back to ``bytes`` implicitly.
+
+.. code-block:: c++
+
+    m.def("asymmetry",
+        [](std::string s) {  // Accepts str or bytes from Python
+            return s;  // Looks harmless, but implicitly converts to str
+        }
+    );
+
+.. code-block:: pycon
+
+    >>> isinstance(example.asymmetry(b"have some bytes"), str)
+    True
+
+    >>> example.asymmetry(b"\xba\xd0\xba\xd0")  # invalid utf-8 as bytes
+    UnicodeDecodeError: 'utf-8' codec can't decode byte 0xba in position 0: invalid start byte
+
+
+Wide character strings
+======================
+
+When a Python ``str`` is passed to a C++ function expecting ``std::wstring``,
+``wchar_t*``, ``std::u16string`` or ``std::u32string``, the ``str`` will be
+encoded to UTF-16 or UTF-32 depending on how the C++ compiler implements each
+type, in the platform's native endianness. When strings of these types are
+returned, they are assumed to contain valid UTF-16 or UTF-32, and will be
+decoded to Python ``str``.
+
+.. code-block:: c++
+
+    #define UNICODE
+    #include <windows.h>
+
+    m.def("set_window_text",
+        [](HWND hwnd, std::wstring s) {
+            // Call SetWindowText with null-terminated UTF-16 string
+            ::SetWindowText(hwnd, s.c_str());
+        }
+    );
+    m.def("get_window_text",
+        [](HWND hwnd) {
+            const int buffer_size = ::GetWindowTextLength(hwnd) + 1;
+            auto buffer = std::make_unique< wchar_t[] >(buffer_size);
+
+            ::GetWindowText(hwnd, buffer.data(), buffer_size);
+
+            std::wstring text(buffer.get());
+
+            // wstring will be converted to Python str
+            return text;
+        }
+    );
+
+Strings in multibyte encodings such as Shift-JIS must transcoded to a
+UTF-8/16/32 before being returned to Python.
+
+
+Character literals
+==================
+
+C++ functions that accept character literals as input will receive the first
+character of a Python ``str`` as their input. If the string is longer than one
+Unicode character, trailing characters will be ignored.
+
+When a character literal is returned from C++ (such as a ``char`` or a
+``wchar_t``), it will be converted to a ``str`` that represents the single
+character.
+
+.. code-block:: c++
+
+    m.def("pass_char", [](char c) { return c; });
+    m.def("pass_wchar", [](wchar_t w) { return w; });
+
+.. code-block:: pycon
+
+    >>> example.pass_char("A")
+    'A'
+
+While C++ will cast integers to character types (``char c = 0x65;``), pybind11
+does not convert Python integers to characters implicitly. The Python function
+``chr()`` can be used to convert integers to characters.
+
+.. code-block:: pycon
+
+    >>> example.pass_char(0x65)
+    TypeError
+
+    >>> example.pass_char(chr(0x65))
+    'A'
+
+If the desire is to work with an 8-bit integer, use ``int8_t`` or ``uint8_t``
+as the argument type.
+
+Grapheme clusters
+-----------------
+
+A single grapheme may be represented by two or more Unicode characters. For
+example 'é' is usually represented as U+00E9 but can also be expressed as the
+combining character sequence U+0065 U+0301 (that is, the letter 'e' followed by
+a combining acute accent). The combining character will be lost if the
+two-character sequence is passed as an argument, even though it renders as a
+single grapheme.
+
+.. code-block:: pycon
+
+    >>> example.pass_wchar("é")
+    'é'
+
+    >>> combining_e_acute = "e" + "\u0301"
+
+    >>> combining_e_acute
+    'é'
+
+    >>> combining_e_acute == "é"
+    False
+
+    >>> example.pass_wchar(combining_e_acute)
+    'e'
+
+Normalizing combining characters before passing the character literal to C++
+may resolve *some* of these issues:
+
+.. code-block:: pycon
+
+    >>> example.pass_wchar(unicodedata.normalize("NFC", combining_e_acute))
+    'é'
+
+In some languages (Thai for example), there are `graphemes that cannot be
+expressed as a single Unicode code point
+<http://unicode.org/reports/tr29/#Grapheme_Cluster_Boundaries>`_, so there is
+no way to capture them in a C++ character type.
+
+
+C++17 string views
+==================
+
+C++17 string views are automatically supported when compiling in C++17 mode.
+They follow the same rules for encoding and decoding as the corresponding STL
+string type (for example, a ``std::u16string_view`` argument will be passed
+UTF-16-encoded data, and a returned ``std::string_view`` will be decoded as
+UTF-8).

+.. _embedding:
+
+Embedding the interpreter
+#########################
+
+While pybind11 is mainly focused on extending Python using C++, it's also
+possible to do the reverse: embed the Python interpreter into a C++ program.
+All of the other documentation pages still apply here, so refer to them for
+general pybind11 usage. 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. For more
+information, see :doc:`/compiling`.
+
+.. code-block:: cmake
+
+    cmake_minimum_required(VERSION 3.4)
+    project(example)
+
+    find_package(pybind11 REQUIRED)  # or `add_subdirectory(pybind11)`
+
+    add_executable(example main.cpp)
+    target_link_libraries(example PRIVATE pybind11::embed)
+
+The essential structure of the ``main.cpp`` file looks like this:
+
+.. code-block:: cpp
+
+    #include <pybind11/embed.h> // everything needed for embedding
+    namespace py = pybind11;
+
+    int main() {
+        py::scoped_interpreter guard{}; // start the interpreter and keep it alive
+
+        py::print("Hello, World!"); // use the Python API
+    }
+
+The interpreter must be initialized before using any Python API, which includes
+all the functions and classes in pybind11. 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 <pybind11/embed.h>
+    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(**kwargs)
+            print(message)
+        )");
+    }
+
+Alternatively, similar results can be achieved using pybind11's API (see
+:doc:`/advanced/pycpp/index` for more details).
+
+.. code-block:: cpp
+
+    #include <pybind11/embed.h>
+    namespace py = pybind11;
+    using namespace py::literals;
+
+    int main() {
+        py::scoped_interpreter guard{};
+
+        auto kwargs = py::dict("name"_a="World", "number"_a=42);
+        auto message = "Hello, {name}! The answer is {number}"_s.format(**kwargs);
+        py::print(message);
+    }
+
+The two approaches can also be combined:
+
+.. code-block:: cpp
+
+    #include <pybind11/embed.h>
+    #include <iostream>
+
+    namespace py = pybind11;
+    using namespace py::literals;
+
+    int main() {
+        py::scoped_interpreter guard{};
+
+        auto locals = py::dict("name"_a="World", "number"_a=42);
+        py::exec(R"(
+            message = "Hello, {name}! The answer is {number}".format(**locals())
+        )", py::globals(), locals);
+
+        auto message = locals["message"].cast<std::string>();
+        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<int>();
+    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 <pybind11/embed.h>
+    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<int>();
+        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 <pybind11/embed.h>
+    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<int>() == 1);
+        assert(locals["b"].cast<int>() == 2);
+
+        py::exec(R"(
+            c = a + b
+            message = fmt.format(a, b, c)
+        )", py::globals(), locals);
+
+        assert(locals["c"].cast<int>() == 3);
+        assert(locals["message"].cast<std::string>() == "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.

+Exceptions
+##########
+
+Built-in C++ to Python exception translation
+============================================
+
+When Python calls C++ code through pybind11, pybind11 provides a C++ exception handler
+that will trap C++ exceptions, translate them to the corresponding Python exception,
+and raise them so that Python code can handle them.
+
+pybind11 defines translations for ``std::exception`` and its standard
+subclasses, and several special exception classes that translate to specific
+Python exceptions. Note that these are not actually Python exceptions, so they
+cannot be examined using the Python C API. Instead, they are pure C++ objects
+that pybind11 will translate the corresponding Python exception when they arrive
+at its exception handler.

+
+Exception translation is not bidirectional. That is, *catching* the C++
+exceptions defined above will not trap exceptions that originate from
+Python. For that, catch :class:`pybind11::error_already_set`. See :ref:`below
+<handling_python_exceptions_cpp>` for further details.
+
+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.
+Similar to pybind11 classes, exception translators can be local to the module
+they are defined in or global to the entire python session.  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<CppExp>(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``.
+
+A matching function is available for registering a local exception translator:
+
+.. code-block:: cpp
+
+    py::register_local_exception<CppExp>(module, "PyExp");
+
+
+It is possible to specify base class for the exception using the third
+parameter, a ``handle``:
+
+.. code-block:: cpp
+
+    py::register_exception<CppExp>(module, "PyExp", PyExc_RuntimeError);
+    py::register_local_exception<CppExp>(module, "PyExp", PyExc_RuntimeError);
+
+Then ``PyExp`` can be caught both as ``PyExp`` and ``RuntimeError``.
+
+The class objects of the built-in Python exceptions are listed in the Python
+documentation on `Standard Exceptions <https://docs.python.org/3/c-api/exceptions.html#standard-exceptions>`_.
+The default base class is ``PyExc_Exception``.
+
+When more advanced exception translation is needed, the functions
+``py::register_exception_translator(translator)`` and
+``py::register_local_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 functions 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). All local translators will be tried
+before a global translator is tried.
+
+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<MyCustomException> 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::
+
+    Call either ``PyErr_SetString`` or a custom exception's call
+    operator (``exc(string)``) for every exception caught in a custom exception
+    translator.  Failure to do so will cause Python to crash with ``SystemError:
+    error return without exception set``.
+
+    Exceptions that you do not plan to handle should simply not be caught, or
+    may be explicitly (re-)thrown to delegate it to the other,
+    previously-declared existing exception translators.
+
+    Note that ``libc++`` and ``libstdc++`` `behave differently <https://stackoverflow.com/questions/19496643/using-clang-fvisibility-hidden-and-typeinfo-and-type-erasure/28827430>`_
+    with ``-fvisibility=hidden``. Therefore exceptions that are used across ABI boundaries need to be explicitly exported, as exercised in ``tests/test_exceptions.h``.
+    See also: "Problems with C++ exceptions" under `GCC Wiki <https://gcc.gnu.org/wiki/Visibility>`_.
+
+
+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.
+
+.. _handling_python_exceptions_cpp:
+
+Handling exceptions from Python in C++
+======================================
+
+When C++ calls Python functions, such as in a callback function or when
+manipulating Python objects, and Python raises an ``Exception``, pybind11
+converts the Python exception into a C++ exception of type
+:class:`pybind11::error_already_set` whose payload contains a C++ string textual
+summary and the actual Python exception. ``error_already_set`` is used to
+propagate Python exception back to Python (or possibly, handle them in C++).
+
+.. tabularcolumns:: |p{0.5\textwidth}|p{0.45\textwidth}|
+
+--------------------------------------+--------------------------------------+
+|  Exception raised in Python          |  Thrown as C++ exception type        |
+======================================+======================================+
+| Any Python ``Exception``             | :class:`pybind11::error_already_set` |
+--------------------------------------+--------------------------------------+
+
+For example:
+
+.. code-block:: cpp
+
+    try {
+        // open("missing.txt", "r")
+        auto file = py::module_::import("io").attr("open")("missing.txt", "r");
+        auto text = file.attr("read")();
+        file.attr("close")();
+    } catch (py::error_already_set &e) {
+        if (e.matches(PyExc_FileNotFoundError)) {
+            py::print("missing.txt not found");
+        } else if (e.matches(PyExc_PermissionError)) {
+            py::print("missing.txt found but not accessible");
+        } else {
+            throw;
+        }
+    }
+
+Note that C++ to Python exception translation does not apply here, since that is
+a method for translating C++ exceptions to Python, not vice versa. The error raised
+from Python is always ``error_already_set``.
+
+This example illustrates this behavior:
+
+.. code-block:: cpp
+
+    try {
+        py::eval("raise ValueError('The Ring')");
+    } catch (py::value_error &boromir) {
+        // Boromir never gets the ring
+        assert(false);
+    } catch (py::error_already_set &frodo) {
+        // Frodo gets the ring
+        py::print("I will take the ring");
+    }
+
+    try {
+        // py::value_error is a request for pybind11 to raise a Python exception
+        throw py::value_error("The ball");
+    } catch (py::error_already_set &cat) {
+        // cat won't catch the ball since
+        // py::value_error is not a Python exception
+        assert(false);
+    } catch (py::value_error &dog) {
+        // dog will catch the ball
+        py::print("Run Spot run");
+        throw;  // Throw it again (pybind11 will raise ValueError)
+    }
+
+Handling errors from the Python C API
+=====================================
+
+Where possible, use :ref:`pybind11 wrappers <wrappers>` instead of calling
+the Python C API directly. When calling the Python C API directly, in
+addition to manually managing reference counts, one must follow the pybind11
+error protocol, which is outlined here.
+
+After calling the Python C API, if Python returns an error,
+``throw py::error_already_set();``, which allows pybind11 to deal with the
+exception and pass it back to the Python interpreter. This includes calls to
+the error setting functions such as ``PyErr_SetString``.
+
+.. code-block:: cpp
+
+    PyErr_SetString(PyExc_TypeError, "C API type error demo");
+    throw py::error_already_set();
+
+    // But it would be easier to simply...
+    throw py::type_error("pybind11 wrapper type error");
+
+Alternately, to ignore the error, call `PyErr_Clear
+<https://docs.python.org/3/c-api/exceptions.html#c.PyErr_Clear>`_.
+
+Any Python error must be thrown or cleared, or Python/pybind11 will be left in
+an invalid state.
+
+Chaining exceptions ('raise from')
+==================================
+
+Python has a mechanism for indicating that exceptions were caused by other
+exceptions:
+
+.. code-block:: py
+
+    try:
+        print(1 / 0)
+    except Exception as exc:
+        raise RuntimeError("could not divide by zero") from exc
+
+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()``.
+
+.. code-block:: cpp
+
+    try {
+        py::eval("print(1 / 0"));
+    } catch (py::error_already_set &e) {
+        py::raise_from(e, PyExc_RuntimeError, "could not divide by zero");
+        throw py::error_already_set();
+    }
+
+.. versionadded:: 2.8
+
+.. _unraisable_exceptions:
+
+Handling unraisable exceptions
+==============================
+
+If a Python function invoked from a C++ destructor or any function marked
+``noexcept(true)`` (collectively, "noexcept functions") throws an exception, there
+is no way to propagate the exception, as such functions may not throw.
+Should they throw or fail to catch any exceptions in their call graph,
+the C++ runtime calls ``std::terminate()`` to abort immediately.
+
+Similarly, Python exceptions raised in a class's ``__del__`` method do not
+propagate, but are logged by Python as an unraisable error. In Python 3.8+, a
+`system hook is triggered
+<https://docs.python.org/3/library/sys.html#sys.unraisablehook>`_
+and an auditing event is logged.
+
+Any noexcept function should have a try-catch block that traps
+class:`error_already_set` (or any other exception that can occur). Note that
+pybind11 wrappers around Python exceptions such as
+:class:`pybind11::value_error` are *not* Python exceptions; they are C++
+exceptions that pybind11 catches and converts to Python exceptions. Noexcept
+functions cannot propagate these exceptions either. A useful approach is to
+convert them to Python exceptions and then ``discard_as_unraisable`` as shown
+below.
+
+.. code-block:: cpp
+
+    void nonthrowing_func() noexcept(true) {
+        try {
+            // ...
+        } catch (py::error_already_set &eas) {
+            // Discard the Python error using Python APIs, using the C++ magic
+            // variable __func__. Python already knows the type and value and of the
+            // exception object.
+            eas.discard_as_unraisable(__func__);
+        } catch (const std::exception &e) {
+            // Log and discard C++ exceptions.
+            third_party::log(e);
+        }
+    }

+Functions
+#########
+
+Before proceeding with this section, make sure that you are already familiar
+with the basics of binding functions and classes, as explained in :doc:`/basics`
+and :doc:`/classes`. 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, py::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}|

+==================================================+============================================================================+
+| :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   |

+| :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     |

+|                                                  | prevents the parent object from being garbage collected as long as the     |
+|                                                  | return value is referenced by Python. This is the default policy for       |

+--------------------------------------------------+----------------------------------------------------------------------------+
+
+Return value policies can also be applied to properties:
+
+.. code-block:: cpp
+
+    class_<MyClass>(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_<MyClass>(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<Nurse, Patient>``
+indicates that the argument with index ``Patient`` should be kept alive at least
+until the argument with index ``Nurse`` is freed by the garbage collector. Argument
+indices start at one, while zero refers to the return value. For methods, index
+``1`` refers to the implicit ``this`` pointer, while regular arguments begin at
+index ``2``. Arbitrarily many call policies can be specified. When a ``Nurse``
+with value ``None`` is detected at runtime, the call policy does nothing.
+
+When the nurse is not a pybind11-registered type, the implementation internally
+relies on the ability to create a *weak reference* to the nurse object. When
+the nurse object is not a pybind11-registered type and does not support weak
+references, an exception will be thrown.
+
+If you use an incorrect argument index, you will get a ``RuntimeError`` saying
+``Could not activate keep_alive!``. You should review the indices you're using.
+
+Consider the following example: here, the binding code for a list append
+operation ties the lifetime of the newly added element to the underlying
+container:
+
+.. code-block:: cpp
+
+    py::class_<List>(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_<Nurse>(m, "Nurse")
+        .def(py::init<Patient &>(), 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<T>`` 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<T>());
+
+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<T1, T2, T3...>``. The
+constructor order is left to right and destruction happens in reverse.
+
+.. seealso::
+
+    The file :file:`tests/test_call_policies.cpp` contains a complete example
+    that demonstrates using `keep_alive` and `call_guard` in more detail.
+
+.. _python_objects_as_args:
+
+Python objects as arguments
+===========================
+
+pybind11 exposes all major Python types using thin C++ wrapper classes. These
+wrapper classes can also be used as parameters of functions in bindings, which
+makes it possible to directly work with native Python types on the C++ side.
+For instance, the following statement iterates over a Python ``dict``:
+
+.. code-block:: cpp
+
+    void print_dict(const py::dict& dict) {
+        /* Easily interact with Python types */
+        for (auto item : dict)
+            std::cout << "key=" << std::string(py::str(item.first)) << ", "
+                      << "value=" << std::string(py::str(item.second)) << std::endl;
+    }
+
+It can be exported:
+
+.. code-block:: cpp
+
+    m.def("print_dict", &print_dict);
+
+And used in Python as usual:
+
+.. code-block:: pycon
+
+    >>> print_dict({"foo": 123, "bar": "hello"})
+    key=foo, value=123
+    key=bar, value=hello
+
+For more information on using Python objects in C++, see :doc:`/advanced/pycpp/index`.
+
+Accepting \*args and \*\*kwargs
+===============================
+
+Python provides a useful mechanism to define functions that accept arbitrary
+numbers of arguments and keyword arguments:
+
+.. code-block:: python
+
+   def generic(*args, **kwargs):
+       ...  # do something with args and kwargs
+
+Such functions can also be created using pybind11:
+
+.. code-block:: cpp
+
+   void generic(py::args args, const py::kwargs& kwargs) {
+       /// .. do something with args
+       if (kwargs)
+           /// .. do something with kwargs
+   }
+
+   /// Binding code
+   m.def("generic", &generic);
+
+The class ``py::args`` derives from ``py::tuple`` and ``py::kwargs`` derives
+from ``py::dict``.
+
+You may also use just one or the other, and may combine these with other
+arguments.  Note, however, that ``py::kwargs`` must always be the last argument
+of the function, and ``py::args`` implies that any further arguments are
+keyword-only (see :ref:`keyword_only_arguments`).
+
+Please refer to the other examples for details on how to iterate over these,
+and on how to cast their entries into C++ objects. A demonstration is also
+available in ``tests/test_kwargs_and_defaults.cpp``.
+
+.. note::
+
+    When combining \*args or \*\*kwargs with :ref:`keyword_args` you should
+    *not* include ``py::arg`` tags for the ``py::args`` and ``py::kwargs``
+    arguments.
+
+Default arguments revisited
+===========================
+
+The section on :ref:`default_args` previously discussed basic usage of default
+arguments using pybind11. One noteworthy aspect of their implementation is that
+default arguments are converted to Python objects right at declaration time.
+Consider the following example:
+
+.. code-block:: cpp
+
+    py::class_<MyClass>("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_<SomeType>``), 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 = <SomeType object at 0x101b7b080>) -> 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>("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>("MyClass")
+        .def("myFunction", py::arg("arg") = static_cast<SomeType *>(nullptr));
+
+.. _keyword_only_arguments:
+
+Keyword-only arguments
+======================
+
+Python implements keyword-only arguments by specifying an unnamed ``*``
+argument in a function definition:
+
+.. code-block:: python
+
+    def f(a, *, b):  # a can be positional or via keyword; b must be via keyword
+        pass
+
+
+    f(a=1, b=2)  # good
+    f(b=2, a=1)  # good
+    f(1, b=2)  # good
+    f(1, 2)  # TypeError: f() takes 1 positional argument but 2 were given
+
+Pybind11 provides a ``py::kw_only`` object that allows you to implement
+the same behaviour by specifying the object between positional and keyword-only
+argument annotations when registering the function:
+
+.. code-block:: cpp
+
+    m.def("f", [](int a, int b) { /* ... */ },
+          py::arg("a"), py::kw_only(), py::arg("b"));
+
+.. versionadded:: 2.6
+
+A ``py::args`` argument implies that any following arguments are keyword-only,
+as if ``py::kw_only()`` had been specified in the same relative location of the
+argument list as the ``py::args`` argument.  The ``py::kw_only()`` may be
+included to be explicit about this, but is not required.
+
+.. versionchanged:: 2.9
+   This can now be combined with ``py::args``. Before, ``py::args`` could only
+   occur at the end of the argument list, or immediately before a ``py::kwargs``
+   argument at the end.
+
+
+Positional-only arguments
+=========================
+
+Python 3.8 introduced a new positional-only argument syntax, using ``/`` in the
+function definition (note that this has been a convention for CPython
+positional arguments, such as in ``pow()``, since Python 2). You can
+do the same thing in any version of Python using ``py::pos_only()``:
+
+.. code-block:: cpp
+
+   m.def("f", [](int a, int b) { /* ... */ },
+          py::arg("a"), py::pos_only(), py::arg("b"));
+
+You now cannot give argument ``a`` by keyword. This can be combined with
+keyword-only arguments, as well.
+
+.. versionadded:: 2.6
+
+.. _nonconverting_arguments:
+
+Non-converting arguments
+========================
+
+Certain argument types may support conversion from one type to another.  Some
+examples of conversions are:
+
+* :ref:`implicit_conversions` declared using ``py::implicitly_convertible<A,B>()``
+* Calling a method accepting a double with an integer argument
+* Calling a ``std::complex<float>`` 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 "<stdin>", line 1, in <module>
+    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_<Dog>(m, "Dog").def(py::init<>());
+    py::class_<Cat>(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 "<stdin>", line 1, in <module>
+    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 <opaque>` types. Pointers to built-in types
+    (``double *``, ``int *``, ...) and STL types (``std::vector<T> *``, ...; 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<T>``
+
+.. _overload_resolution:
+
+Overload resolution order
+=========================
+
+When a function or method with multiple overloads is called from Python,
+pybind11 determines which overload to call in two passes.  The first pass
+attempts to call each overload without allowing argument conversion (as if
+every argument had been specified as ``py::arg().noconvert()`` as described
+above).
+
+If no overload succeeds in the no-conversion first pass, a second pass is
+attempted in which argument conversion is allowed (except where prohibited via
+an explicit ``py::arg().noconvert()`` attribute in the function definition).
+
+If the second pass also fails a ``TypeError`` is raised.
+
+Within each pass, overloads are tried in the order they were registered with
+pybind11. If the ``py::prepend()`` tag is added to the definition, a function
+can be placed at the beginning of the overload sequence instead, allowing user
+overloads to proceed built in functions.
+
+What this means in practice is that pybind11 will prefer any overload that does
+not require conversion of arguments to an overload that does, but otherwise
+prefers earlier-defined overloads to later-defined ones.
+
+.. note::
+
+    pybind11 does *not* further prioritize based on the number/pattern of
+    overloaded arguments.  That is, pybind11 does not prioritize a function
+    requiring one conversion over one requiring three, but only prioritizes
+    overloads requiring no conversion at all to overloads that require
+    conversion of at least one argument.
+
+.. versionadded:: 2.6
+
+    The ``py::prepend()`` tag.
+
+Binding functions with template parameters
+==========================================
+
+You can bind functions that have template parameters. Here's a function:
+
+.. code-block:: cpp
+
+    template <typename T>
+    void set(T t);
+
+C++ templates cannot be instantiated at runtime, so you cannot bind the
+non-instantiated function:
+
+.. code-block:: cpp
+
+    // BROKEN (this will not compile)
+    m.def("set", &set);
+
+You must bind each instantiated function template separately. You may bind
+each instantiation with the same name, which will be treated the same as
+an overloaded function:
+
+.. code-block:: cpp
+
+    m.def("set", &set<int>);
+    m.def("set", &set<std::string>);
+
+Sometimes it's more clear to bind them with separate names, which is also
+an option:
+
+.. code-block:: cpp
+
+    m.def("setInt", &set<int>);
+    m.def("setString", &set<std::string>);

+
+General notes regarding convenience macros
+==========================================
+
+pybind11 provides a few convenience macros such as
+:func:`PYBIND11_DECLARE_HOLDER_TYPE` and ``PYBIND11_OVERRIDE_*``. 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_OVERRIDE(MyReturnType<T1, T2>, Class<T3, T4>, 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<T1, T2>;
+    using ClassType = Class<T3, T4>;
+    PYBIND11_OVERRIDE(ReturnType, ClassType, func);
+
+    // Version 2: using the PYBIND11_TYPE macro:
+    PYBIND11_OVERRIDE(PYBIND11_TYPE(MyReturnType<T1, T2>),
+                      PYBIND11_TYPE(Class<T3, T4>), 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_OVERRIDE_PURE(
+                std::string, /* Return type */
+                Animal,      /* Parent class */
+                go,          /* Name of function */
+                n_times      /* Argument(s) */
+            );
+        }
+    };
+
+    PYBIND11_MODULE(example, m) {
+        py::class_<Animal, PyAnimal> animal(m, "Animal");
+        animal
+            .def(py::init<>())
+            .def("go", &Animal::go);
+
+        py::class_<Dog>(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<py::gil_scoped_release>());
+
+
+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> pet(m, "Pet");
+    pet.def(py::init<const std::string &>())
+       .def_readwrite("name", &Pet::name);
+
+    py::class_<Dog>(m, "Dog", pet /* <- specify parent */)
+        .def(py::init<const std::string &>())
+        .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_<Dog>``.
+However, it can be acquired as follows:
+
+.. code-block:: cpp
+
+    py::object pet = (py::object) py::module_::import("basic").attr("Pet");
+
+    py::class_<Dog>(m, "Dog", pet)
+        .def(py::init<const std::string &>())
+        .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_<Dog, Pet>(m, "Dog")
+        .def(py::init<const std::string &>())
+        .def("bark", &Dog::bark);
+
+Naturally, both methods will fail when there are cyclic dependencies.
+
+Note that pybind11 code compiled with hidden-by-default symbol visibility (e.g.
+via the command line flag ``-fvisibility=hidden`` on GCC/Clang), which is
+required for proper pybind11 functionality, can interfere with the ability to
+access types defined in another extension module.  Working around this requires
+manually exporting types that are accessed by multiple extension modules;
+pybind11 provides a macro to do just this:
+
+.. code-block:: cpp
+
+    class PYBIND11_EXPORT Dog : public Animal {
+        ...
+    };
+
+Note also that it is possible (although would rarely be required) to share arbitrary
+C++ objects between extension modules at runtime. Internal library data is shared
+between modules using capsule machinery [#f6]_ which can be also utilized for
+storing, modifying and accessing user-defined data. Note that an extension module
+will "see" other extensions' data if and only if they were built with the same
+pybind11 version. Consider the following example:
+
+.. code-block:: cpp
+
+    auto data = reinterpret_cast<MyData *>(py::get_shared_data("mydata"));
+    if (!data)
+        data = static_cast<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 collected
+    py::cpp_function cleanup_callback(
+        [](py::handle weakref) {
+            // perform cleanup here -- this function is called with the GIL held
+
+            weakref.dec_ref(); // release weak reference
+        }
+    );
+
+    // Create a weak reference with a cleanup callback and initially leak it
+    (void) py::weakref(m.attr("BaseClass"), cleanup_callback).release();
+
+.. note::
+
+    PyPy does not garbage collect objects when the interpreter exits. An alternative
+    approach (which also works on CPython) is to use the :py:mod:`atexit` module [#f7]_,
+    for example:
+
+    .. code-block:: cpp
+
+        auto atexit = py::module_::import("atexit");
+        atexit.attr("register")(py::cpp_function([]() {
+            // perform cleanup here -- this function is called with the GIL held
+        }));
+
+    .. [#f7] https://docs.python.org/3/library/atexit.html
+
+
+Generating documentation using Sphinx
+=====================================
+
+Sphinx [#f4]_ has the ability to inspect the signatures and documentation
+strings in pybind11-based extension modules to automatically generate beautiful
+documentation in a variety formats. The python_example repository [#f5]_ contains a
+simple example repository which uses this approach.
+
+There are two potential gotchas when using this approach: first, make sure that
+the resulting strings do not contain any :kbd:`TAB` characters, which break the
+docstring parsing routines. You may want to use C++11 raw string literals,
+which are convenient for multi-line comments. Conveniently, any excess
+indentation will be automatically be removed by Sphinx. However, for this to
+work, it is important that all lines are indented consistently, i.e.:
+
+.. code-block:: cpp
+
+    // ok
+    m.def("foo", &foo, R"mydelimiter(
+        The foo function
+
+        Parameters
+        ----------
+    )mydelimiter");
+
+    // *not ok*
+    m.def("foo", &foo, R"mydelimiter(The foo function
+
+        Parameters
+        ----------
+    )mydelimiter");
+
+By default, pybind11 automatically generates and prepends a signature to the docstring of a function
+registered with ``module_::def()`` and ``class_::def()``. Sometimes this
+behavior is not desirable, because you want to provide your own signature or remove
+the docstring completely to exclude the function from the Sphinx documentation.
+The class ``options`` allows you to selectively suppress auto-generated signatures:
+
+.. code-block:: cpp
+
+    PYBIND11_MODULE(example, m) {
+        py::options options;
+        options.disable_function_signatures();
+
+        m.def("add", [](int a, int b) { return a + b; }, "A function which adds two numbers");
+    }
+
+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
+.. [#f5] http://github.com/pybind/python_example
+
+.. _avoiding-cpp-types-in-docstrings:
+
+Avoiding C++ types in docstrings
+================================
+
+Docstrings are generated at the time of the declaration, e.g. when ``.def(...)`` is called.
+At this point parameter and return types should be known to pybind11.
+If a custom type is not exposed yet through a ``py::class_`` constructor or a custom type caster,
+its C++ type name will be used instead to generate the signature in the docstring:
+
+.. code-block:: text
+
+     |  __init__(...)
+     |      __init__(self: example.Foo, arg0: ns::Bar) -> None
+                                              ^^^^^^^
+
+
+This limitation can be circumvented by ensuring that C++ classes are registered with pybind11
+before they are used as a parameter or return type of a function:
+
+.. code-block:: cpp
+
+    PYBIND11_MODULE(example, m) {
+
+        auto pyFoo = py::class_<ns::Foo>(m, "Foo");
+        auto pyBar = py::class_<ns::Bar>(m, "Bar");
+
+        pyFoo.def(py::init<const ns::Bar&>());
+        pyBar.def(py::init<const ns::Foo&>());
+    }

+
+Buffer protocol
+===============
+
+Python supports an extremely general and convenient approach for exchanging
+data between plugin libraries. Types can expose a buffer view [#f2]_, which
+provides fast direct access to the raw internal data representation. Suppose we
+want to bind the following simplistic Matrix class:
+
+.. code-block:: cpp
+
+    class Matrix {
+    public:
+        Matrix(size_t rows, size_t cols) : m_rows(rows), m_cols(cols) {
+            m_data = new float[rows*cols];
+        }
+        float *data() { return m_data; }
+        size_t rows() const { return m_rows; }
+        size_t cols() const { return m_cols; }
+    private:
+        size_t m_rows, m_cols;
+        float *m_data;
+    };
+
+The following binding code exposes the ``Matrix`` contents as a buffer object,
+making it possible to cast Matrices into NumPy arrays. It is even possible to
+completely avoid copy operations with Python expressions like
+``np.array(matrix_instance, copy = False)``.
+
+.. code-block:: cpp
+
+    py::class_<Matrix>(m, "Matrix", py::buffer_protocol())
+       .def_buffer([](Matrix &m) -> py::buffer_info {
+            return py::buffer_info(
+                m.data(),                               /* Pointer to buffer */
+                sizeof(float),                          /* Size of one scalar */
+                py::format_descriptor<float>::format(), /* Python struct-style format descriptor */
+                2,                                      /* Number of dimensions */
+                { m.rows(), m.cols() },                 /* Buffer dimensions */
+                { sizeof(float) * m.cols(),             /* Strides (in bytes) for each index */
+                  sizeof(float) }
+            );
+        });
+
+Supporting the buffer protocol in a new type involves specifying the special
+``py::buffer_protocol()`` tag in the ``py::class_`` constructor and calling the
+``def_buffer()`` method with a lambda function that creates a
+``py::buffer_info`` description record on demand describing a given matrix
+instance. The contents of ``py::buffer_info`` mirror the Python buffer protocol
+specification.
+
+.. code-block:: cpp
+
+    struct buffer_info {
+        void *ptr;
+        py::ssize_t itemsize;
+        std::string format;
+        py::ssize_t ndim;
+        std::vector<py::ssize_t> shape;
+        std::vector<py::ssize_t> strides;
+    };
+
+To create a C++ function that can take a Python buffer object as an argument,
+simply use the type ``py::buffer`` as one of its arguments. Buffers can exist
+in a great variety of configurations, hence some safety checks are usually
+necessary in the function body. Below, you can see a basic example on how to
+define a custom constructor for the Eigen double precision matrix
+(``Eigen::MatrixXd``) type, which supports initialization from compatible
+buffer objects (e.g. a NumPy matrix).
+
+.. code-block:: cpp
+
+    /* Bind MatrixXd (or some other Eigen type) to Python */
+    typedef Eigen::MatrixXd Matrix;
+
+    typedef Matrix::Scalar Scalar;
+    constexpr bool rowMajor = Matrix::Flags & Eigen::RowMajorBit;
+
+    py::class_<Matrix>(m, "Matrix", py::buffer_protocol())
+        .def(py::init([](py::buffer b) {
+            typedef Eigen::Stride<Eigen::Dynamic, Eigen::Dynamic> Strides;
+
+            /* Request a buffer descriptor from Python */
+            py::buffer_info info = b.request();
+
+            /* Some basic validation checks ... */
+            if (info.format != py::format_descriptor<Scalar>::format())
+                throw std::runtime_error("Incompatible format: expected a double array!");
+
+            if (info.ndim != 2)
+                throw std::runtime_error("Incompatible buffer dimension!");
+
+            auto strides = Strides(
+                info.strides[rowMajor ? 0 : 1] / (py::ssize_t)sizeof(Scalar),
+                info.strides[rowMajor ? 1 : 0] / (py::ssize_t)sizeof(Scalar));
+
+            auto map = Eigen::Map<Matrix, 0, Strides>(
+                static_cast<Scalar *>(info.ptr), info.shape[0], info.shape[1], strides);
+
+            return Matrix(map);
+        }));
+
+For reference, the ``def_buffer()`` call for this Eigen data type should look
+as follows:
+
+.. code-block:: cpp
+
+    .def_buffer([](Matrix &m) -> py::buffer_info {
+        return py::buffer_info(
+            m.data(),                                /* Pointer to buffer */
+            sizeof(Scalar),                          /* Size of one scalar */
+            py::format_descriptor<Scalar>::format(), /* Python struct-style format descriptor */
+            2,                                       /* Number of dimensions */
+            { m.rows(), m.cols() },                  /* Buffer dimensions */
+            { sizeof(Scalar) * (rowMajor ? m.cols() : 1),
+              sizeof(Scalar) * (rowMajor ? 1 : m.rows()) }
+                                                     /* Strides (in bytes) for each index */
+        );
+     })
+
+For a much easier approach of binding Eigen types (although with some
+limitations), refer to the section on :doc:`/advanced/cast/eigen`.
+
+.. seealso::
+
+    The file :file:`tests/test_buffers.cpp` contains a complete example

+
+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<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<double> array);
+
+When it is invoked with a different type (e.g. an integer or a list of
+integers), the binding code will attempt to cast the input into a NumPy array
+of the requested type. This feature requires the :file:`pybind11/numpy.h`
+header to be included. Note that :file:`pybind11/numpy.h` does not depend on
+the NumPy headers, and thus can be used without declaring a build-time
+dependency on NumPy; NumPy>=1.7.0 is a runtime dependency.
+
+Data in NumPy arrays is not guaranteed to packed in a dense manner;
+furthermore, entries can be separated by arbitrary column and row strides.
+Sometimes, it can be useful to require a function to only accept dense arrays
+using either the C (row-major) or Fortran (column-major) ordering. This can be
+accomplished via a second template argument with values ``py::array::c_style``
+or ``py::array::f_style``.
+
+.. code-block:: cpp
+
+    void f(py::array_t<double, py::array::c_style | py::array::forcecast> array);
+
+The ``py::array::forcecast`` argument is the default value of the second
+template parameter, and it ensures that non-conforming arguments are converted
+into an array satisfying the specified requirements instead of trying the next
+function overload.
+
+There are several methods on arrays; the methods listed below under references
+work, as well as the following functions based on the NumPy API:
+
+- ``.dtype()`` returns the type of the contained values.
+
+- ``.strides()`` returns a pointer to the strides of the array (optionally pass
+  an integer axis to get a number).
+
+- ``.flags()`` returns the flag settings. ``.writable()`` and ``.owndata()``
+  are directly available.
+
+- ``.offset_at()`` returns the offset (optionally pass indices).
+
+- ``.squeeze()`` returns a view with length-1 axes removed.
+
+- ``.view(dtype)`` returns a view of the array with a different dtype.
+
+- ``.reshape({i, j, ...})`` returns a view of the array with a different shape.
+  ``.resize({...})`` is also available.
+
+- ``.index_at(i, j, ...)`` gets the count from the beginning to a given index.
+
+
+There are also several methods for getting references (described below).
+
+Structured types
+================
+
+In order for ``py::array_t`` to work with structured (record) types, we first
+need to register the memory layout of the type. This can be done via
+``PYBIND11_NUMPY_DTYPE`` macro, called in the plugin definition code, which
+expects the type followed by field names:
+
+.. code-block:: cpp
+
+    struct A {
+        int x;
+        double y;
+    };
+
+    struct B {
+        int z;
+        A a;
+    };
+
+    // ...
+    PYBIND11_MODULE(test, m) {
+        // ...
+
+        PYBIND11_NUMPY_DTYPE(A, x, y);
+        PYBIND11_NUMPY_DTYPE(B, z, a);
+        /* now both A and B can be used as template arguments to py::array_t */
+    }
+
+The structure should consist of fundamental arithmetic types, ``std::complex``,
+previously registered substructures, and arrays of any of the above. Both C++
+arrays and ``std::array`` are supported. While there is a static assertion to
+prevent many types of unsupported structures, it is still the user's
+responsibility to use only "plain" structures that can be safely manipulated as
+raw memory without violating invariants.
+
+Vectorizing functions
+=====================
+
+Suppose we want to bind a function with the following signature to Python so
+that it can process arbitrary NumPy array arguments (vectors, matrices, general
+N-D arrays) in addition to its normal arguments:
+
+.. code-block:: cpp
+
+    double my_func(int x, float y, double z);
+
+After including the ``pybind11/numpy.h`` header, this is extremely simple:
+
+.. code-block:: cpp
+
+    m.def("vectorized_func", py::vectorize(my_func));
+
+Invoking the function like below causes 4 calls to be made to ``my_func`` with
+each of the array elements. The significant advantage of this compared to
+solutions like ``numpy.vectorize()`` is that the loop over the elements runs
+entirely on the C++ side and can be crunched down into a tight, optimized loop
+by the compiler. The result is returned as a NumPy array of type
+``numpy.dtype.float64``.
+
+.. code-block:: pycon
+
+    >>> x = np.array([[1, 3], [5, 7]])
+    >>> y = np.array([[2, 4], [6, 8]])
+    >>> z = 3
+    >>> result = vectorized_func(x, y, z)
+
+The scalar argument ``z`` is transparently replicated 4 times.  The input
+arrays ``x`` and ``y`` are automatically converted into the right types (they
+are of type  ``numpy.dtype.int64`` but need to be ``numpy.dtype.int32`` and
+``numpy.dtype.float32``, respectively).
+
+.. note::
+
+    Only arithmetic, complex, and POD types passed by value or by ``const &``
+    reference are vectorized; all other arguments are passed through as-is.
+    Functions taking rvalue reference arguments cannot be vectorized.
+
+In cases where the computation is too complicated to be reduced to
+``vectorize``, it will be necessary to create and access the buffer contents
+manually. The following snippet contains a complete example that shows how this
+works (the code is somewhat contrived, since it could have been done more
+simply using ``vectorize``).
+
+.. code-block:: cpp
+
+    #include <pybind11/pybind11.h>
+    #include <pybind11/numpy.h>
+
+    namespace py = pybind11;
+
+    py::array_t<double> add_arrays(py::array_t<double> input1, py::array_t<double> 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<double>(buf1.size);
+
+        py::buffer_info buf3 = result.request();

+
+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<T>`` template
+class offer an unchecked proxy object that can be used for this unchecked
+access through the ``unchecked<N>`` and ``mutable_unchecked<N>`` methods,
+where ``N`` gives the required dimensionality of the array:
+
+.. code-block:: cpp
+
+    m.def("sum_3d", [](py::array_t<double> x) {
+        auto r = x.unchecked<3>(); // x must have ndim = 3; can be non-writeable
+        double sum = 0;
+        for (py::ssize_t i = 0; i < r.shape(0); i++)
+            for (py::ssize_t j = 0; j < r.shape(1); j++)
+                for (py::ssize_t k = 0; k < r.shape(2); k++)
+                    sum += r(i, j, k);
+        return sum;
+    });
+    m.def("increment_3d", [](py::array_t<double> x) {
+        auto r = x.mutable_unchecked<3>(); // Will throw if ndim != 3 or flags.writeable is false
+        for (py::ssize_t i = 0; i < r.shape(0); i++)
+            for (py::ssize_t j = 0; j < r.shape(1); j++)
+                for (py::ssize_t k = 0; k < r.shape(2); k++)
+                    r(i, j, k) += 1.0;
+    }, py::arg().noconvert());
+
+To obtain the proxy from an ``array`` object, you must specify both the data
+type and number of dimensions as template arguments, such as ``auto r =
+myarray.mutable_unchecked<float, 2>()``.
+
+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<T>()``.  This will give you a proxy object that works in the
+same way, but results in less optimizable code and thus a small efficiency
+loss in tight loops.
+
+Note that the returned proxy object directly references the array's data, and
+only reads its shape, strides, and writeable flag when constructed.  You must
+take care to ensure that the referenced array is not destroyed or reshaped for
+the duration of the returned object, typically by limiting the scope of the
+returned instance.
+
+The returned proxy object supports some of the same methods as ``py::array`` so
+that it can be used as a drop-in replacement for some existing, index-checked
+uses of ``py::array``:
+
+- ``.ndim()`` returns the number of dimensions
+
+- ``.data(1, 2, ...)`` and ``r.mutable_data(1, 2, ...)``` returns a pointer to
+  the ``const T`` or ``T`` data, respectively, at the given indices.  The
+  latter is only available to proxies obtained via ``a.mutable_unchecked()``.
+
+- ``.itemsize()`` returns the size of an item in bytes, i.e. ``sizeof(T)``.
+
+- ``.ndim()`` returns the number of dimensions.
+
+- ``.shape(n)`` returns the size of dimension ``n``
+
+- ``.size()`` returns the total number of elements (i.e. the product of the shapes).
+
+- ``.nbytes()`` returns the number of bytes used by the referenced elements
+  (i.e. ``itemsize()`` times ``size()``).
+
+.. seealso::
+
+    The file :file:`tests/test_numpy_array.cpp` contains additional examples
+    demonstrating the use of this feature.
+
+Ellipsis
+========
+
+Python provides a convenient ``...`` ellipsis notation that is often used to
+slice multidimensional arrays. For instance, the following snippet extracts the
+middle dimensions of a tensor with the first and last index set to zero.
+
+.. code-block:: python
+
+   a = ...  # a NumPy array
+   b = a[0, ..., 0]
+
+The function ``py::ellipsis()`` function can be used to perform the same
+operation on the C++ side:
+
+.. code-block:: cpp
+
+   py::array a = /* A NumPy array */;
+   py::array b = a[py::make_tuple(0, py::ellipsis(), 0)];
+
+
+Memory view
+===========
+
+For a case when we simply want to provide a direct accessor to C/C++ buffer
+without a concrete class object, we can return a ``memoryview`` object. Suppose
+we wish to expose a ``memoryview`` for 2x4 uint8_t array, we can do the
+following:
+
+.. code-block:: cpp
+
+    const uint8_t buffer[] = {
+        0, 1, 2, 3,
+        4, 5, 6, 7
+    };
+    m.def("get_memoryview2d", []() {
+        return py::memoryview::from_buffer(
+            buffer,                                    // buffer pointer
+            { 2, 4 },                                  // shape (rows, cols)
+            { sizeof(uint8_t) * 4, sizeof(uint8_t) }   // strides in bytes
+        );
+    })
+
+This approach is meant for providing a ``memoryview`` for a C/C++ buffer not
+managed by Python. The user is responsible for managing the lifetime of the
+buffer. Using a ``memoryview`` created in this way after deleting the buffer in
+C++ side results in undefined behavior.
+
+We can also use ``memoryview::from_memory`` for a simple 1D contiguous buffer:
+
+.. code-block:: cpp
+
+    m.def("get_memoryview1d", []() {
+        return py::memoryview::from_memory(
+            buffer,               // buffer pointer
+            sizeof(uint8_t) * 8   // buffer size
+        );
+    })
+
+.. versionchanged:: 2.6
+    ``memoryview::from_memory`` added.
