Add the following to your ~/.hammerspoon/init.lua
:
PaperWM = hs.loadSpoon("PaperWM")
PaperWM:bindHotkeys({
-- switch to a new focused window in tiled grid
focus_left = {{"alt", "cmd"}, "left"},
focus_right = {{"alt", "cmd"}, "right"},
focus_up = {{"alt", "cmd"}, "up"},
focus_down = {{"alt", "cmd"}, "down"},
-- move windows around in tiled grid
swap_left = {{"alt", "cmd", "shift"}, "left"},
swap_right = {{"alt", "cmd", "shift"}, "right"},
swap_up = {{"alt", "cmd", "shift"}, "up"},
swap_down = {{"alt", "cmd", "shift"}, "down"},
-- position and resize focused window
center_window = {{"alt", "cmd"}, "c"},
full_width = {{"alt", "cmd"}, "f"},
cycle_width = {{"alt", "cmd"}, "r"},
reverse_cycle_width = {{"ctrl", "alt", "cmd"}, "r"},
cycle_height = {{"alt", "cmd", "shift"}, "r"},
reverse_cycle_height = {{"ctrl", "alt", "cmd", "shift"}, "r"},
-- move focused window into / out of a column
slurp_in = {{"alt", "cmd"}, "i"},
barf_out = {{"alt", "cmd"}, "o"},
-- move the focused window into / out of the tiling layer
toggle_floating = {{"alt", "cmd", "shift"}, "escape"},
-- switch to a new Mission Control space
switch_space_l = {{"alt", "cmd"}, ","},
switch_space_r = {{"alt", "cmd"}, "."},
switch_space_1 = {{"alt", "cmd"}, "1"},
switch_space_2 = {{"alt", "cmd"}, "2"},
switch_space_3 = {{"alt", "cmd"}, "3"},
switch_space_4 = {{"alt", "cmd"}, "4"},
switch_space_5 = {{"alt", "cmd"}, "5"},
switch_space_6 = {{"alt", "cmd"}, "6"},
switch_space_7 = {{"alt", "cmd"}, "7"},
switch_space_8 = {{"alt", "cmd"}, "8"},
switch_space_9 = {{"alt", "cmd"}, "9"},
-- move focused window to a new space and tile
move_window_1 = {{"alt", "cmd", "shift"}, "1"},
move_window_2 = {{"alt", "cmd", "shift"}, "2"},
move_window_3 = {{"alt", "cmd", "shift"}, "3"},
move_window_4 = {{"alt", "cmd", "shift"}, "4"},
move_window_5 = {{"alt", "cmd", "shift"}, "5"},

})
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 effect
Set 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
)
