git clone https://github.com/mogenson/PaperWM.spoon ~/.hammerspoon/Spoons/PaperWM.spoon. -
Open
System Preferences->Mission Control. Uncheck "Automatically rearrange Spaces based on most recent use" and check "Displays have separate Spaces".

PaperWM:start()Feel free to customize hotkeys or use
PaperWM:bindHotkeys(PaperWM.default_hotkeys) for defaults. PaperWM actions are also
available for manual keybinding via the PaperWM.actions table; for example, the
following would enable navigation by either arrow keys or vim-style h/j/k/l directions:
PaperWM = hs.loadSpoon("PaperWM")
PaperWM:bindHotkeys(PaperWM.default_hotkeys)
hs.hotkey.bind({"ctrl", "alt", "cmd"}, "h", PaperWM.actions.focus_left)
hs.hotkey.bind({"ctrl", "alt", "cmd"}, "j", PaperWM.actions.focus_down)
hs.hotkey.bind({"ctrl", "alt", "cmd"}, "k", PaperWM.actions.focus_up)
hs.hotkey.bind({"ctrl", "alt", "cmd"}, "l", PaperWM.actions.focus_right)
hs.hotkey.bind({"ctrl", "alt", "cmd", "shift"}, "h", PaperWM.actions.swap_left)
hs.hotkey.bind({"ctrl", "alt", "cmd", "shift"}, "j", PaperWM.actions.swap_down)
hs.hotkey.bind({"ctrl", "alt", "cmd", "shift"}, "k", PaperWM.actions.swap_up)
hs.hotkey.bind({"ctrl", "alt", "cmd", "shift"}, "l", PaperWM.actions.swap_right)PaperWM:start() will begin automatically tiling new and existing windows. PaperWM:stop() will
release control over windows.
Set PaperWM.window_gap to the number of pixels to space between windows and
the top and bottom screen edges.
Configure one or many PaperWM.window_filter:rejectApp("appName") to ignore specific applications. For example:
PaperWM.window_filter:rejectApp("iStat Menus Status")
PaperWM.window_filter:rejectApp("Finder")
PaperWM:start() -- restart for new window filter to take effectSet PaperWM.window_ratios to the ratios to cycle window widths and heights
through. For example:
PaperWM.window_ratios = { 0.23607, 0.38195, 0.61804 }MacOS does not allow a window to be moved fully off-screen. Windows that would be tiled off-screen are placed in a margin on the left and right edge of the screen. They are still visible and clickable.
It's difficult to detect when a window is dragged from one space or screen to
another. Use the move_window_N commands to move windows between spaces and
screens.
Arrange screens vertically to prevent windows from bleeding into other screens.
The following Spoons compliment PaperWM.spoon nicely.
- ActiveSpace.spoon Show active and layout of Mission Control spaces in the menu bar.
- Swipe.spoon Perform actions when trackpad swipe gestures are recognized. Here's an example config to change PaperWM.spoon focused window:
-- focus adjacent window with 3 finger swipe
local current_id, threshold
Swipe = hs.loadSpoon("Swipe")
Swipe:start(3, function(direction, distance, id)
if id == current_id then
if distance > threshold then
threshold = math.huge -- trigger once per swipe
-- use "natural" scrolling
if direction == "left" then
PaperWM.actions.focus_right()
elseif direction == "right" then
PaperWM.actions.focus_left()
elseif direction == "up" then
PaperWM.actions.focus_down()
elseif direction == "down" then
PaperWM.actions.focus_up()
end
end
else
current_id = id
threshold = 0.2 -- swipe distance > 20% of trackpad size
end
end)Contributions are welcome! Here are a few preferences:
- Global variables are
CamelCase(eg.PaperWM) - Local variables are
snake_case(eg.local focused_window) - Function names are
lowerCamelCase(eg.function windowEventHandler()) - Use
<const>where possible - Create a local copy when deeply nested members are used often (eg.
local Watcher <const> = hs.uielement.watcher)
