Qtile

* features
- The Battery widget now supports dynamic charge control, allowing for
protecting battery life.
- To support the above (plus the other widgets that modify sysfs), qtile
now ships with its own udev rules, located at
/resources/99-qtile.rules; distro packagers will probably want to
install this rule set.
* bugfixes
- Fix groups marked with `persist=False` not being deleted when their last window is moved to another group.
- Fallback icon in StatusNotifier widget

!!! config breakage/changes !!!
- Matches no longer use "include/substring" style matching. But match the string exactly. Previously on X11, if the WM_TYPE of a spawned window is e.g. dialog a match with wm_type dialognoonereadschangelogs would return true. Additionally a window with an empty WM_CLASS (which can happen) would match anything. If you rely this style of substring matching, pass a regex to your match or use a function with func=.
Using a list of strings inside Match with role, title, wm_class, wm_instance_class, wm_type are also deprecated, use a regex. Right now we replace the property with a regex if it's a list and warn with a deprecation message. You can use "qtile migrate" to migrate your config to this.
* features
- Change how `tox` runs tests. See https://docs.qtile.org/en/latest/manual/contributing.html#running-tests-locally
for more information on how to run tests locally.
- Add `ScreenSplit` layout which allows multiple layouts per screen. Also adds `ScreenSplit`
widget to display name of active split.
- Updated `Bluetooth` widget which allows users to manage multiple devices in a single widget
- Add `align` option to `Columns` layout so new windows can be added to left or right column.
- `.when()` have two new parameters:
- `func: Callable`: Enable call when the result of the callable evaluates to True
- `condition: bool`: a boolean value to determine whether the lazy object should be run. Unlike `func`, the
condition is evaluated once when the config file is first loaded.
- Add ability to have bar drawns over windows by adding `reserve=False` to bar's config to
stop the bar reserving screen space.
- Add ability for third-party code (widgets, layouts) to create hooks
- Add ability to create user-defined hooks which can be fired from external scripts
* bugfixes
- Fix two bugs in stacking transient windows in X11
- Checking configs containing `qtile.core.name` with `python config.py` don't fail anymore (but `qtile.core.name`
will be `None`)
- Fix an error if a wayland xwindow has unknown wm_type

!!! Dependency Changes !!!
- xcffib must be upgraded to >= 1.4.0
- cairocffi must be upgraded to >= 1.6.0
- New optional dependency `pulsectl-asyncio` required for `PulseVolume` widget
!!! Notice for packagers - wlroots (optional dependency) bump !!!
- Qtile's wayland backend now requires on wlroots 0.16 (and pywlroots 0.16)
!!! config breakage/changes !!!
- The `cmd_` prefix has been dropped from all commands (this means command names are common when accessed
via the command interface or internal python objects).
- Custom widgets should now expose command methods with the `expose_command` decorator (available via
`from libqtile.command.base import expose_command`).
- Some commands have been renamed (in addition to dropping the 'cmd_' prefix):
`hints` -> `get_hints`
`groups` -> `get_groups`
`screens` -> `get_screens`
- Layouts need to rename some methods:
- `add` to `add_client`
- `cmd_next` to `next`
- `cmd_previous` to `previous`
- Layouts or widgets that redefine the `commands` property need to update the signature:
`expose_command()`
`def commands(self) -> list[str]:`
- `Window.getsize` has been renamed `Window.get_size` (i.e. merged with the get_size command).
- `Window.getposition` has been renamed `Window.get_position` (i.e. merged with the get_position command).
- The `StockTicker` widget `function` option is being deprecated: rename it to `func`.
- The formatting of `NetWidget` has changed, if you use the `format` parameter in your config include
`up_suffix`, `total_suffix` and `down_suffix` to display the respective units.
- The `Notify` widget now has separate `default_timeout` properties for differenct urgency levels. Previously,
`default_timeout` was `None` which meant that there was no timeout for all notifications (unless this had been
set by the client sending the notification). Now, `default_timeout` is for normal urgency notifications and this
has been set to a default of 10 seconds. `default_timeout_urgent`, for critical notifications, has a timeout of `None`.
- The `PulseVolume` widget now depends on a third party library, `pulsectl-asyncio`, to interact with the pulse audio
server. Users will now see an `ImportError` until they install that library.
* features
- Add ability to set icon size in `LaunchBar` widget.
- Add 'warp_pointer' option to `Drag` that when set will warp the pointer to the bottom right of
the window when dragging begins.
- Add `currentsong` status to `Mpd2` widget.
- Add ability to disable group toggling in `GroupBox` widget
- Add ability to have different border color when windows are stacked in Stack layout. Requires
setting `border_focus_stack` and `border_normal_stack` variables.
- Add ability to have different single border width for Columns layout by setting 'single_border_width' key.
- Add ability to have different border and margin widths when VerticalTile layout only contains 1 window by
setting 'single_border_width' and 'single_margin' keys.
- New widget: GenPollCommand
- Add `format` and `play_icon` parameters for styling cmus widget.
- Add ability to add a group at a specified index
- Add ability to spawn the `WidgetBox` widget opened.
- Add ability to swap focused window based on index, and change the order of windows inside current group
- Add ability to update the widget only once if `update_interval` is None.
- Add `move_to_slice` command to move current window to single layout in `Slice` layout
- Made the `NetWidget` text formattable.
- Qtile no longer floods the log following X server disconnection, instead handling those errors.
- `Key` and `KeyChord` bindings now have another argument `swallow`.
It indicates whether or not the pressed keys should be passed on to the focused client.
By default the keys are not passed (swallowed), so this argument is set to `True`.
When set to `False`, the keys are passed to the focused client. A key is never swallowed if the
function is not executed, e.g. due to failing the `.when()` check.
- Add ability to set custom "Undefined" status key value to `Mpd2Widget`.
- `Mpd2Widget` now searches for artist name in all similar keys (i.e `albumartist`, `performer`, etc.).
- Add svg support to `CustomLayoutIcon`
- added layering controls for X11 (Wayland support coming soon!):
- `lazy.window.keep_above()/keep_below()` marks windows to be kept above/below other windows permanently.
Calling the functions with no arguments toggles the state, otherwise pass `enable=True` or `enable=False`.
- `lazy.window.move_up()/move_down()` moves windows up and down the z axis.
- added `only_focused` setting to Max layout, allowing to draw multiple clients on top of each other when
set to False
- Add `suspend` hook to run functions before system goes to sleep.
* bugfixes
- Fix bug where Window.center() centers window on the wrong screen when using multiple monitors.
- Fix `Notify` bug when apps close notifications.
- Fix `CPU` precision bug with specific version of `psutil`
- Fix config being reevaluated twice during reload (e.g. all hooks from config were doubled)

- Fix `Battery` widget on FreeBSD without explicit `battery` index given.
- Fix XMonad layout faulty call to nonexistent _shrink_up
- Fix setting tiled position by mouse for layouts using _SimpleLayoutBase. To support this in other layouts, add a swap method taking two windows.
- Fix unfullscreening bug in conjunction with Chromium based clients when auto_fullscreen is set to `False`.
- Ensure `CurrentLayoutIcon` expands paths for custom folders.
- Fix vertical alignment of icons in `TaskList` widget
- Fix laggy resize/positioning of floating windows in X11 by handling motion notify events later. We also introduced a cap setting if you want to limit these events further, e.g. for limiting resource usage. This is configurable with the x11_drag_polling_rate variable for each `Screen` which is set to None by default, indicating no cap.
* python version support
- We have added support for python 3.11 and pypy 3.9.
- python 3.7, 3.8 and pypy 3.7 are not longer supported.
- Fix bug where `StatusNotifier` does not update icons

!!! Config breakage !!!
- lazy.qtile.display_kb() no longer receives any arguments. If you passed it any arguments
(which were ignored previously), remove them.
- If you have a custom startup Python script that you use instead of `qtile start` and run init_log
manually, the signature has changed. Please check the source for the updated arguments.
- `KeyChord`'s signature has changed. ``mode`` is now a boolean to indicate whether the mode should persist.
The ``name`` parameter should be used to name the chord (e.g. for the ``Chord`` widget).
* features
- Add ability to draw borders and add margins to the `Max` layout.
- The default XWayland cursor is now set at startup to left_ptr, so an xsetroot call is not needed to
avoid the ugly X cursor.

- Add icon theme support to `TaskList` widget (available on X11 and Wayland backends).
- Wayland: Use `qtile cmd-obj -o core -f get_inputs` to get input device identifiers for
configuring inputs. Also input configs will be updated by config reloads (pywlroots>=0.15.21)
* bugfixes
- Widgets that are incompatible with a backend (e.g. Systray on Wayland) will no longer show
as a ConfigError in the bar. Instead the widget is silently removed from the bar and a message
included in the logs.

- Fix bug where widgets can't be mirrored in same bar.
- Fix various issues with setting fullscreen windows floating and vice versa.
- Fix a bug where a .when() check for lazy functions errors out when matching
on focused windows when none is focused. By default we do not match on focused windows,
to change this set `if_no_focused` to True.
