Visualize yabai window stacks on macOS. Works with yabai & hammerspoon.
Current status
Unfortunately, I've haven't been able to work on this project since Q3 2021. Initially, this was due to a scary bout of RSI-esque finger pain that entirely prevented from me from typing (really – I had to use Talon for basic computer use); The lesson I took away is that my hobbies shouldn't invovlve continuous typing (given I'm already typing all day for work).
I apologize that I won't be working on this anymore – but that doesn't mean you can't fork & carry the torch ;)

stackline
adds unobtrusive visual indicators to complement yabai
's window stacking functionality.
A 'stack' enables multiple macOS windows to occupy the same screen space and behave as a single unit.
Stacks are a recent addition (June 2020) to the (excellent!) macOS tiling window manager koekeishiya/yabai. See yabai #203 for more info about yabai
's stacking feature. Currently, there's no built-in UI for stacks, which makes it easy to forget about stacked windows that aren't visible or get disoriented.
Enter stackline
: unobtrusive visual indicators that complement yabai
window stacks.
stackline v0.1.55
Icon indicators… | …or minimal indicators |
---|---|
See wiki for example keybindings to create and navigate between stacks.
# Get the repo
git clone https://github.com/AdamWagner/stackline.git ~/.hammerspoon/stackline
# Make stackline run when hammerspoon launches
cd ~/.hammerspoon
echo 'stackline = require "stackline"' >> init.lua
echo 'stackline:init()' >> init.lua
Now your ~/.hammerspoon
directory should look like this:
├── init.lua
└── stackline
├── conf.lua
├── stackline
│ ├── configmanager.lua
│ ├── query.lua
│ ├── stack.lua
│ ├── stackline.lua
│ ├── stackmanager.lua
│ └── window.lua
└── lib
└── …
This is an optional step. It's required to send configuration commands to stackline
from scripts, for example:
# Toggle boolean values with the hs cli
hs -c "stackline.config:toggle('appearance.showIcons')"
Type hs.ipc.cliInstall()
and hit return
If Hammerspoon is installed via Brew on Apple Silicon, hs.ipc.cliInstall("/opt/homebrew")
#2930
hs
is available by entering the following in your terminal (shell):❯ which hs
/usr/local/bin/hs
Open the Hammperspoon console via the menu bar | Type `hs.ipc.cliInstall()` and hit return |
---|---|
yabai
(or make sure it's running) (brew services start yabai
)hammerspoon
(or make sure it's running) (open -a "Hammerspoon"
)Create a window stack
Now, assuming you've been issuing these commands from a terminal and also have a browser window open on the same space, make sure your terminal is positioned immediately to the left of your browser and issue the following command (or use keybindings) to create a stack:
yabai -m window --stack next
Did the terminal window expand to cover the area previously occupied by Safari? Great! At this point, you should notice two app icons at the top-left corner of your terminal window, like this:
You can toggle minimalist mode by turning the icons off:
hs -c 'stackline.config:toggle("appearance.showIcons")'
See the wiki to for details about how to do this with a key binding.
All are welcome. Feel free to dive in by opening an issue or submitting a PR.
@alin23 initially proposed the concept for stackline here and encouraged @AdamWagner to share the mostly-broken proof-of-concept publicly. Since then, @alin23 dramatically improved upon the initial proof-of-concept with #13, has some pretty whiz-bang functionality on deck with #17, and has been a great thought partner/reviewer.
@zweck, who, in the same thread, got the gears turning about how @alin23's idea could be implemented and also urged Adam to share his POC.
@johnallen3d for being of one the first folks to install stackline, and for identifying several mistakes & gaps in the setup instructions.
@pete-may for saving folks from frustration by fixing an out-of-date command in the readme (#48)
@AdamWagner wrote the initial proof-of-concept (POC) for stackline.
Give a ⭐️ if you think (a more fully-featured version of) stackline would be useful!
Thanks to @koekeishiya without whom the wonderful yabai would not exist, and projects like this would have no reason to exist.
Similarly, thanks to @dominiklohmann, who has helped so many people make chunkwm/yabai "do the thing" they want and provides great feedback on new and proposed yabai features.
Thanks to @cmsj, @asmagill, and all of the contributors to hammerspoon for making macos APIs accessible to the rest of us!
Thanks to the creators & maintainers of the lua utility libraries underscore.lua, lume.lua, and self.lua.
