Class Spaces

The spaces for a particular display.

Spaces.__init__(self, display_index=0, *, cg_conn: Optional[inspect._empty] = <objc.function '_CGSDefaultConnection' at 0x11af9dc50>): Initialise.

Parameters:

• display_index: optional display index, default 0
• cg_conn: optional CoreGraphics connection, default from CoreGraphics._CGSDefaultConnection()

Spaces.__getitem__(self, space_index): Return the space at index space_index. Note that the index counts from 0, while the desktop space number counts from 1.

Spaces.current: The current space.

Spaces.current_index: The index of the current space, found by scanning the spaces for the current space UUID. Returns None if not found.

Spaces.current_uuid: The UUID of the current space.

Spaces.display_id: The display identifier of the display.

Spaces.display_uuid: The UUID of the display.

Spaces.forget(self): Forget the current spaces information. This will cause it to be obtained anew.

Spaces.get_wp_config(self, space_index: int): Get the desktop picture configuration of the space at space_index.

Spaces.monitor_current(self, **kw): Return a cs.delta.monitor generator for changes to the "current" space i.e. changes representing a desktop space switch.

Spaces.monitor_wp_config(self, space_index=None, **kw): Return a cs.delta.monitor generator for the wallpaper configuration of a specific space (default self.current_index at the time of call).

Spaces.popindices(self, argv): Pop a leading spaces specification from argv if present, return a list of the indices it represents. If there is no spaces specification, return None.

Note that space indices count from 0, and space numbers count from 1.

The following spaces specifications are recognised:

• .: the current space index
• *: all the space indices
• a positive integer spn: spn-1

Spaces.set_wp_config(self, space_index: int, wp_config: dict): Set the desktop picture configuration of the space at space_index using the dict wp_config.

Spaces.set_wp_fspath(self, space_index: int, fspath: str, *, background_color=(0, 0, 0), random=True, change_duration=5.0, placement='SizeToFit'): Set the Space configuration of space_index to use images from fspath.

Spaces.spaces_pathfor(fspath: str): Return fspath adjusted for use in a spaces configuration.

Prior to MacOS Sonoma (14.5), this just returns the absolute path.

In MacOS Sonoma there's some hideous bug in the DesktopPictureSetDisplayForSpace library where it seems to see a leading home directory path and replace it with /~ (instead of something plausible like '~'), perhaps intended for making paths track homedir moves. It turns out that providing a relative path from '/' does The Right Thing. Ugh.

Class SpacesCommand(cs.cmdutils.BaseCommand)

A command line implementation for manipulating spaces.

SpacesCommand.Options

SpacesCommand.cmd_current(self, argv): Usage: {cmd} Print the current space number.

SpacesCommand.cmd_monitor(self, argv): Usage: {cmd} Monitor space switches.

SpacesCommand.cmd_wp(self, argv): Usage: {cmd} [{{.|space#|}} [wp-path]] Set or query the wallpaper for a space. The optional space number may be "." to indicate the current space or "" to indicate all spaces.

SpacesCommand.cmd_wpm(self, argv): Usage: {cmd} [{{.|space#}}] Monitor the wallpaper settings of a particular space.

SpacesCommand.run_context(self, **kw): Set options.spaces to a Spaces instnace during a command run.
