Miro Windows Manager

With this script you will be able to move windows around your screen by using your keyboard!

Windows can be resized to full-screen or resized in halves or in corners using your keyboard.

This can all be done by using a special (i.e. hyper) key in your keyboard and arrows. Other projects instead move windows in halves using arrows, and in corners using other counterintuitive shortcuts, like letters, which makes things confusing.

This script needs Hammerspoon in order to work.

How to install

• Extract the zip file, containing MiroWindowsManager.spoon in ~/.hammerspoon/Spoons
• Now you need to configure Hammerspoon in order to load this spoon in ~/.hammerspoon/Spoons/MiroWindowsManager.spoon adding the following snippet of code in your init.lua file:

local hyper = {"ctrl", "alt", "cmd"}

hs.loadSpoon("MiroWindowsManager")

hs.window.animationDuration = 0.3
spoon.MiroWindowsManager:bindHotkeys({
  up = {hyper, "up"},
  right = {hyper, "right"},
  down = {hyper, "down"},
  left = {hyper, "left"},
  fullscreen = {hyper, "f"}
})

Shortcuts

In the snippet above configure Miro'w Windows Manager in the following way:

Hyper key

The hyper key is defined as ctrl + alt + cmd. This means that each shortcut will start by pressing these three keys. If you consider this too verbose for your personal keyboard interactions, you can also change it, for example replacing it with an unused key (e.g. caps lock key) with Karabiner and Seil to act as hyper key.

Move in halves

• hyper + up: move to the top half of the screen
• hyper + right: move to the right half of the screen
• hyper + down: move to the bottom half of the screen
• hyper + left: move to the left half of the screen

By repeating these shortcuts the window is resized to be one third or two thirds and again in one half.

Move to corners

• hyper + up + right: move the window to the top-right corner
• hyper + down + right: move the window to the bottom-right corner
• hyper + up + left: move the window to the top-left corner
• hyper + down + left: move the window to the bottom-left corner

When the window is in the corner, it will have one half of screen height and one half of screen width. The arrows can be used to expand the height/width to be one third, two thirds or again one half. For example if the window is in the top-right corner, pressing hyper + up the window height will be resized to be one third, while pressing hyper + right the window width will be resized to be one third; in this case hyper + left and hyper + down will move the window to the top-left and bottom-right corners, respectively.

Expand to fit the entire height or width

These are useful in case the window is in one of the corners.

• hyper + up + down: expand the height to fit the entire screen height
• hyper + right + left: expand the width to fit the entire screen width

Expand to fullscreen

• hyper + f: expand to be full screen

Note that in case the window is resized to be a half of the screen, you can also use hyper + up + down (or hyper + right + left) to resize the window full screen.

As the other shortcuts, hyper + f can be pressed multiple times to obtain a centered window of three fourth and one half of height and width. This behaviour can be customized.

Animations

The snippet above configures the animation to last 0.3s with hs.window.animationDuration = 0.3. To remove the animations completely change this value to 0.

Reviews

Here comments from the users, just as reviews.

I can’t thank you enough for you windows management Spoon. It’s the best window manager for Mac OS out there.

— Jacopo

it's something I have been looking for all my life! It is really intuitive and ingenious once you see the magic it can do.

— rxng

Really loving the arrow based positioning, thanks for making this ! I can now uninstall “spectacle” which I was using for the same purpose but the key bindings were unintuitive.

— Gaurav

the only issue I have with miro-windows-manager is the fact that I didn't discover it sooner. just getting into HammerSpoon and love this 🥄 ... so handy, nice work @miromannino !
