1.9.3 (Feb 05, 2025)

  • Fix several memory leaks in input.c.

  • Raise the minimum supported Python version to 3.9 and the setuptools version to 77.0.

1.9.2 (May 01, 2025)

  • Add the “–reproducible” build option which removes the build date and used headers from the generated ecodes.c. Example usage:

    python -m build --config-setting=--build-option='build_ecodes --reproducible' -n

  • Use Generic to set precise type for InputDevice.path.

1.9.1 (Feb 22, 2025)

  • Fix fox missing UI_FF constants in generated ecodes.py.

  • More type annotations.

1.9.0 (Feb 08, 2025)

  • Fix for CPATH/C_INCLUDE_PATH being ignored during build.

  • Slightly faster reading of events in device.read() and device.read_one().

  • Fix FreeBSD support.

  • Drop deprecated InputDevice.fn (use InputDevice.path instead).

  • Improve type hint coverage and add a py.typed file to the sdist.

1.8.0 (Jan 25, 2025)

  • Binary wheels are now provided by the evdev-binary package. The package is compiled on manylinux_2_28 against kernel 4.18.

  • The evdev.ecodes module is now generated at install time and contains only constants. This allows type checking and introspection of the evdev.ecodes module, without having to execute it first. The old module is available as evdev.ecodes_runtime. In case generation of the static ecodes.py fails, the install process falls back to using ecodes_runtime.py as ecodes.py.

  • Reverse mappings in evdev.ecodes that point to more than one value are now tuples instead of lists. For example:

    >>> ecodes.KEY[153]
('KEY_DIRECTION', 'KEY_ROTATE_DISPLAY')

  • Raise the minimum supported Python version to 3.8.

  • Fix keyboard delay and repeat being swapped (#227).

  • Move the syn() convenience method from InputDevice to EventIO (#224).

1.7.1 (May 8, 2024)

  • Provide fallback value for FF_MAX_EFFECTS, which fixes the build on EL 7 (#219).

  • Add #ifdef guards around UI_GET_SYSNAME to improve kernel compatibility (#218) .

  • Wait up to two seconds for uinput devices to appear. (#215)

1.7.0 (Feb 18, 2024)

  • Respect the CPATH/C_INCLUDE_PATH environment variables during install.

  • Add the uniq address to the string representation of InputDevice.

  • Improved method for finding the device node corresponding to a uinput device (#206).

  • Fix generation of ecodes.c when the path to sys.executable contains spaces.

1.6.0 (Jul 17, 2022)

  • Fix Python 3.11 compatibility (#174).

  • Fix documentation (#163, #160).

  • Re-enable TTY echo at evtest exit (#155).

  • Fix ImportError: sys.meta_path is None, Python is likely shutting down (#154).

  • Closing the input device file descriptor in InputDevice.close() now happens in the main thread, instead of in a new thread (reverts #146).

  • Fix util.find_ecodes_by_regex not working across all supported Python versions (#152).

1.4.0 (Jan 16, 2021)

  • Fix InputDevice.set_absinfo to allow setting parameters to zero.

  • Fix off-by-one in ioctl_EVIOCG_bits, which causes value at the end of the list to not be reported back (#131).

  • Fix set_absinfo to allow setting parameters to zero (#128).

  • Fix leak when returning BlockingIOError from a read (#143).

  • Fix “There is no current event loop in thread” error for non asyncio code (#146).

1.3.0 (Jan 12, 2020)

  • Fix build on 32bit arches with 64bit time_t

  • Add functionality to query device properties. See InputDevice.input_props and the input_props argument to Uinput.

  • KeyEvent received an allow_unknown constructor argument, which determines what will happen when an event code cannot be mapped to a keycode. The default and behavior so far has been to raise KeyError. If set to True, the keycode will be set to the event code formatted as a hex number.

  • Add InputDevice.set_absinfo() and InputDevice.absinfo().

  • Instruct the asyncio event loop to stop monitoring the fd of the input device when the device is closed.

1.2.0 (Apr 7, 2019)

  • Add UInput support for the resolution parameter in AbsInfo. This brings support for the new method of uinput device setup, which was introduced in Linux 4.5 (thanks to @LinusCDE).

  • Vendor and product identifiers can be greater or equal to 0x8000 (thanks @ivaradi).

1.1.2 (Sep 1, 2018)

  • Fix installation on kernels <= 4.4.

  • Fix uinput creation ignoring absinfo settings.

1.1.0 (Aug 27, 2018)

  • Fix Uinput device creation raising KeyError when a capability filtered by default is not present.

  • The InputDevice.fn attribute was deprecated in favor of InputDevice.path. Using the former will show a DeprecationWarning, but would otherwise continue working as before.

  • Fix InputDevice comparison raising AttributeError due to a non-existant path attribute.

  • Fix asyncio support in Python 3.5+.

  • Uploading FF effect now works both on Python 2.7 and Python 3+.

  • Remove the asyncore example from the tutorial.

0.8.1 (Mar 24, 2018)

  • Fix Python 2 compatibility issue in with Uinput.from_device.

  • Fix minor evdev.evtest formatting issue.

0.8.0 (Mar 22, 2018)

  • Fix InputDevice comparison on Python 2.

  • The device path is now considered when comparing two devices.

  • Fix UInput.from_device not correctly merging the capabilities of selected devices.

  • The list of excluded event types in UInput.from_device is now configurable. For example:

    UInput.from_device(dev, filtered_types=(EV_SYN, EV_FF))

    In addition, ecodes.EV_FF is now excluded by default.

  • Add a context manager for grabbing access to a device - InputDevice.grab_context. For example:

    with dev.grab_context():
    pass

  • Add the InputDevice.uniq attribute, which contains the unique identifier of the device. As with phys, this attribute may be empty (i.e. ‘’).

0.7.0 (Jun 16, 2017)

  • InputDevice now accepts objects that support the path protocol. For example:

    pth = pathlib.Path('/dev/input/event0')
dev = evdev.InputDevice(pth)

  • Support path protocol in InputDevice. This means that InputDevice instances can be passed to callers that expect a os.PathLike object.

  • Exceptions raised during InputDevice.async_read() (and similar) are now handled properly (i.e. an exception is set on the returned future instead of leaking that exception into the event loop) (Fixes #67).

0.6.4 (Oct 07, 2016)

  • Exclude ecodes.c from source distribution (Fixes #63).

0.6.3 (Oct 06, 2016)

  • Add the UInput.from_device class method, which allows uinput device to be created with the capabiltiies of one or more existing input devices:

    ui = UInput.from_device('/dev/input1', '/dev/input2', **constructor_kwargs)

  • Add the build_ecodes distutils command, which generates the ecodes.c extension module. The new way of overwriting the evdev header locations is:

    python setup.py build \
  build_ecodes --evdev-headers path/input.h:path/input-event-codes.h \
  build_ext --include-dirs  path/ \
  install

    The build* and install commands no longer have to be part of the same command-line (i.e. running install will reuse the outputs of the last build).

0.6.1 (Jun 04, 2016)

  • Disable tty echoing while evtest is running.

  • Allow evtest to listen to more than one devices.

  • The setup.py script now allows the location of the input header files to be overwritten. For example:

    python setup.py build_ext \
  --evdev-headers path/input.h:path/input-event-codes.h \
  --include-dirs  path/ \
  install

0.6.0 (Feb 14, 2016)

  • Asyncio and async/await support (many thanks to @paulo-raca).

  • Add the ability to set the phys property of uinput devices (thanks @paulo-raca).

  • Add a generic InputDevice.set() method (thanks @paulo-raca).

  • Distribute the evtest script along with evdev.

  • Fix issue with generating ecodes.c in recent kernels (>= 4.4.0).

  • Fix absinfo item indexes in UInput.uinput_create() (thanks @forsenonlhaimaisentito).

  • More robust comparison of InputDevice objects (thanks @isia).

0.5.0 (Jun 16, 2015)

  • Write access to the input device is no longer mandatory. Evdev will first try to open the device for reading and writing and fallback to read-only. Methods that require write access (e.g. set_led()) will raise EvdevError if the device is open only for reading.

0.4.7 (Oct 07, 2014)

  • Fallback to distutils if setuptools is not available.

0.4.6 (Oct 07, 2014)

  • Rework documentation and docstrings once more.

  • Fix install on Python 3.4 (works around issue21121).

  • Fix ioctl() requested buffer size (thanks Jakub Wojciech Klama).

0.4.5 (Jul 06, 2014)

  • Add method for returning a list of the currently active keys - InputDevice.active_keys() (thanks @spasche).

  • Fix a potential buffer overflow in ioctl_capabilities() (thanks @spasche).

0.4.4 (Jun 04, 2014)

  • Calling InputDevice.read_one() should always return None, when there is nothing to be read, even in case of a EAGAIN errno (thanks JPP).

0.4.3 (Dec 19, 2013)

  • Silence OSError in destructor (thanks @polyphemus).

  • Make InputDevice.close() work in cases in which stdin (fd 0) has been closed (thanks @polyphemus).

0.4.2 (Dec 13, 2013)

  • Rework documentation and docstrings.

  • Call InputDevice.close() from InputDevice.__del__().

0.4.1 (Jul 24, 2013)

0.4.0 (Jul 01, 2013)

  • Add FF_* and FF_STATUS codes to ecodes() (thanks @bgilbert).

  • Reverse event code mappings (ecodes.{KEY,FF,REL,ABS} and etc.) will now map to a list of codes, whenever a value corresponds to multiple codes:

    >>> ecodes.KEY[152]
... ['KEY_COFFEE', 'KEY_SCREENLOCK']
>>> ecodes.KEY[30]
... 'KEY_A'

  • Set the state of a LED through InputDevice.set_led() (thanks @accek).

  • Open InputDevice.fd in O_RDWR mode from now on.

  • Fix segfault in InputDevice.device_read_many() (thanks @bgilbert).

0.3.3 (May 29, 2013)

  • Raise IOError from InputDevice.device_read() and InputDevice.device_read_many() when InputDevice.read() fails.

  • Several stability and style changes (thank you debian code reviewers).

0.3.2 (Apr 05, 2013)

  • Fix vendor id and product id order in DeviceInfo() (thanks @kived).

0.3.1 (Nov 23, 2012)

  • InputDevice.read() will return an empty tuple if the device has nothing to offer (instead of segfaulting).

  • Exclude unnecessary package data in sdist and bdist.

0.3.0 (Nov 06, 2012)

  • Add ability to set/get auto-repeat settings with EVIOC{SG}REP.

  • Add InputDevice.version() - the value of EVIOCGVERSION.

  • Add InputDevice.read_loop().

  • Add InputDevice.grab() and InputDevice.ungrab() - exposes EVIOCGRAB.

  • Add InputDevice.leds() - exposes EVIOCGLED.

  • Replace DeviceInfo class with a namedtuple.

  • Prevent InputDevice.read_one() from skipping events.

  • Rename AbsData to AbsInfo (as in struct input_absinfo).

0.2.0 (Aug 22, 2012)

  • Add the ability to set arbitrary device capabilities on uinput devices (defaults to all EV_KEY ecodes).

  • Add UInput.device which is an open InputDevice to the input device that uinput ‘spawns’.

  • Add UInput.capabilities() which is just a shortcut to UInput.device.capabilities().

  • Rename UInput.write() to UInput.write_event().

  • Add a simpler UInput.write(type, code, value)() method.

  • Make all UInput() constructor arguments optional (default device name is now py-evdev-uinput).

  • Add the ability to set absmin, absmax, absfuzz and absflat when specifying the uinput device’s capabilities.

  • Remove the nophys argument - if a device fails the EVIOCGPHYS ioctl, phys will equal the empty string.

  • Make InputDevice.capabilities() perform a EVIOCGABS ioctl for devices that support EV_ABS and return that info wrapped in an AbsData namedtuple.

  • Split ioctl_devinfo into ioctl_devinfo and ioctl_capabilities.

  • Split UInput.uinput_open() to UInput.uinput_open() and UInput.uinput_create()

  • Add events.keys, which is a combination of all BTN_ and KEY_ event codes.

  • ecodes.c was not generated when installing through pip.

0.1.0 (May 17, 2012)
