Create/remove Spaces? #280

Open anijatsu opened 3 years ago

anijatsu commented 3 years ago

Version: 2.6.2
macOS: 11.4 (ARM64/M1) Hi! Browsing through the JS API doc here on Github, and through the Safari Web Developer console (hence the old version I've noted here) I couldn't figure out a way to create or remove a Space (as in virtual desktop). I do see the Space.constructor object, but can't figure out whether it's usable or not. I'd really appreciate an example on how to call the Space object to remove or add a new desktop, if it is possible.

@anijatsu Hey! Unfortunately Apple does not provide an API for this. In fact, all the Spaces functionalities are not officially supported by Apple and use private internal APIs.

Raised a suggestion via Apple's Feedback Manager for a new public API to become accessible. ID is FB9319058, in case anyone would want to follow in my steps.

Hi! There’s some hints around the internet about CGSCreateSpace/CGSTransactionCreateSpace/SLSTransactionCreateSpace and the same for destroy in the private APIs, but they don’t seem to be available to link when building.

@kasper CGSSpaceCreate works, even in macOS 12.2. requires a dock restart to show up (killall Dock)

CGSSpaceCreate(CGSDefaultConnection(), 0, [
  "type": 0, // 0 is CGSSpaceTypeUser (https://github.com/NUIKit/CGSInternal/blob/master/CGSSpace.h)
  "uuid": UUID().uuidString as CFString,
] as CFDictionary)

other usage on GH:

@kaatt Hah, I was trying with the wrong order in the function name. Thanks! Obviously killing the Dock is not really something that Phoenix should do.

kaatt commented 2 years ago

there may be an undiscovered/entitlement-gated function that makes the space show without killing dock. maybe you can expose an api to kill dock so its up to the user
