AeroSpace

AeroSpace is a tiling window manager for macOS.

Status

🚧 Work in progress. Not usable yet 🚧

I will publish first release once I believe it's usable, so subscribe to releases on GitHub:

Key features

• Manual tiling window manager
• i3 inspired
• AeroSpace employs its own emulation of virtual workspaces instead of relying on native macOS Spaces due to their considerable limitations
• Plain text configuration (dotfiles friendly)
• [PLANNED] CLI scriptable
• Doesn't require disabling SIP (System Integrity Protection)
• Proper multi-monitor support (i3-like paradigm)
• Status menu icon displays current workspace name

How to build the project

You would need a Mac.

Firstly, install xcodegen. Then run in terminal:

./build-debug.sh

How to run the tests

./run-tests.sh

Todo

• is dialog, is resizable, is modal?
• select parent and kill several windows at once
• select parent -> outline several windows?
  • OR: outline with "SLSSetWindowOpacity"
  • OR: "shake" windows
• CLI interface
• Check all todos in code
• move vs swap
• what is src/Assets.xcassets ?
• license
• unminimize apps automatically
• minimized apps handling
• macOS fullscreen apps handling
• unhide apps automatically

Challenges

• Window overlapping
• "floating" window layout
• windows' min/max sizes

Known Special windows to check

• XCode welcome screen
• Finder preview
• Toolbox window
• IntelliJ dialog windows (e.g. "Add to git")
• IntelliJ project structure modal window
• VLC full screen window (eh, I wish every fullscreen window in macOS worked like that)
• iTerm drop down window

Limitations of macOS API

• It's not possible to find to what monitor window is assigned
• It's not possible to reliably know what monitor is currently active
