Installing Spoons

spoon.SpoonInstall:andUse("WindowScreenLeftAndRight")

Loading Spoons

hs.loadSpoon("SpoonInstall")

Starting Application

hs.application.launchOrFocus("Safari")
local safari = hs.appfinder.appFromName("Safari")

Seeing the status of an application

function applicationWatcher(appName, eventType, appObject)
    if (eventType == hs.application.watcher.activated) then
        if (appName == "Finder") then
            -- Bring all Finder windows forward when one gets activated
            appObject:selectMenuItem({"Window", "Bring All to Front"})
        end
    end
end
appWatcher = hs.application.watcher.new(applicationWatcher)
appWatcher:start()

Opening an application

hs.application.open('com.brave.Browser')

Quitting an application

hs.application.find('com.todoist.mac.Todoist'):kill()

Names of Applications (run in console)

hs.fnutils.each(hs.application.runningApplications(), function(app) print(app:title()) end)

BundleID (run in console)

osascript -e 'id of app "Name of App"'

Start a chooser

hs.chooser.new(function(choice)
 
      local toggl = require('Spoons/Headspace/toggl')
      toggl.startTimer(hs.settings.get("secrets").toggl.projects.binge, choice.text)
 
      -- Open URL of choice
      hs.urlevent.openURL(choice.url)
    end)
    :choices({
      {
        text = 'Netflix',
        url = 'http://netflix.com/'

Usages

Application blocking

function stopApp(name)
  app = hs.application.get(name)
  if app and app:isRunning() then
    app:kill()
  end
end
 
function forceKillProcess(name)
  hs.execute("pkill " .. name)
end
 
function startApp(name)

    doReload = false
    for _,file in pairs(files) do
        if file:sub(-4) == ".lua" then
            doReload = true
        end

    if doReload then
        hs.reload()
    end
end
myWatcher = hs.pathwatcher.new(os.getenv("HOME") .. "/.hammerspoon/", reloadConfig):start()hs.alert.show("Config loaded")

Hotkey variables

ctrl_cmd = {"cmd", "ctrl"}
cmd_alt = {"cmd", "alt"}
shift_ctrl_cmd = {"shift", "cmd", "ctrl"}

Window management

hs.loadSpoon("SpoonInstall")
hs.loadSpoon("MiroWindowsManager")
 
hs.window.animationDuration = 0
spoon.MiroWindowsManager:bindHotkeys({
    up =         { cmd_alt, "up" },
    right =      { cmd_alt, "right" },
    down =       { cmd_alt, "down" },
    left =       { cmd_alt, "left" },
    fullscreen = { cmd_alt, "m" }
   }
)
 
spoon.SpoonInstall:andUse("WindowScreenLeftAndRight")
spoon.WindowScreenLeftAndRight.animationDuration = 0
spoon.WindowScreenLeftAndRight:bindHotkeys(
{
  screen_left = { ctrl_cmd, "Left" },
  screen_right= { ctrl_cmd, "Right" },
})
