hs.tiling

Add tiling window management powers to your [hammerspoon][hammerspoon]. (Fork of nathankot’s mjolnir.tiling.)

Features

• Different layouts per space ([with this magic][magic])
• Multi-monitor supported
• Custom layouts

Quick start

First up, install [Hammerspoon][hammerspoon] if you haven’t already.

Then install hs.tiling by cloning into your hammerspoon configuration directory:

mkdir -p $HOME/.hammerspoon/hs
git clone https://github.com/dsanson/hs.tiling $HOME/.hammerspoon/hs/tiling

In your ~/.hammerspoon/init.lua:

local tiling = require "hs.tiling"
local hotkey = require "hs.hotkey"
local mash = {"ctrl", "cmd"}

hotkey.bind(mash, "c", function() tiling.cycleLayout() end)
hotkey.bind(mash, "j", function() tiling.cycle(1) end)
hotkey.bind(mash, "k", function() tiling.cycle(-1) end)
hotkey.bind(mash, "space", function() tiling.promote() end)
hotkey.bind(mash, "f", function() tiling.goToLayout("fullscreen") end)

-- If you want to set the layouts that are enabled
tiling.set('layouts', {
  'fullscreen', 'main-vertical'
})

Updating

To update to the latest hs.tiling, pull the latest from git:

cd $HOME/.hammerspoon/hs/tiling
git pull

Using custom layouts

You can define your own layouts like so (please see [layouts.lua]!(/layouts.lua) for definition examples:)

tiling.addLayout('custom', function(windows)
  fnutils.each(windows, function(window)
    window:maximize()
  end)
end)

Floating Windows

Using tiling.toggleFloat you can toggle whether or not a window that is on your desktop will be included in your tiling calculations. You can optionally pass in a function as a callback to process the window if it was tiled.

-- Push the window into the exact center of the screen
local function center(window)
  frame = window:screen():frame()
  frame.x = (frame.w / 2) - (frame.w / 4)
  frame.y = (frame.h / 2) - (frame.h / 4)
  frame.w = frame.w / 2
  frame.h = frame.h / 2
  window:setFrame(frame)
end

hotkey.bind(mash, "f", function() tiling.toggleFloat(center) end)

Layouts

These are the layouts that come with hs.tiling:

Name	Screenshot
fullscreen
main-vertical
main-horizontal
rows
columns
gp-vertical
gp-horizontal

Variable Layouts

I am experimenting with adding support for variable width layouts.

For now, I have added a variable width variant of main-vertical, called main-vertical-variable. It it just like main-vertical, except the proportion of the screen filled by the main window is determined by the value of the global variable, mainVertical, which defaults to 0.5. I’ve also added two functions, tiling.setMainVertical(val), which takes a value between 0 and 1 (0.25 means that the main window takes a quarter of the screen, while the other windows take the remaining three quarters; 0.75 means that the main window takes 3/4 of the screen, while the remaining windows take 1/4, and so on) and tiling.adjustMainVertical(factor), which takes a negative or positive factor by which to adjust the value of mainVertical (e.g., if mainVertical is 0.5, then tiling.adjustMainVertical(-0.1) sets it to 0.4).

Here is how I use them in my init.lua (as part of a “windows” mode using hotkeys.modal:

w:bind({},"left",  function() tiling.adjustMainVertical(-0.05) end)
w:bind({},"right",  function() tiling.adjustMainVertical(0.05) end)
w:bind({},"=", function() tiling.setMainVertical(0.5) end)

Once I have all the kinks worked out, I plan to enable this feature for main-vertical and gp-vertical, as well as a corresponding feature for main-horizontal and gp-horizontal.

Contributors

This is a port of nathankot’s [mjolnir.tiling][mjolnir.tiling].

I replaced references to mjolnir extensions (e.g., mjolnir.window) with references to the corresponding hammerspoon extensions (e.g., hs.window). I rewrote function calls in camelCase where necessary. I renamed tiling.lua to init.lua. It seems to work.

Thanks to Nathan and all these contributors for making mjolnir.tiling, and making it so easy to port over to hammerspoon!

To-do

• Better documentation
• More layouts
• Allow globally enabling/disabling layouts
• Functions to move windows across spaces
• Event-based tiling, although requires [sdegutis/mjolnir#72][72]
