Hammerspoon – Lua-based powerful tool automation of macOS

Re:Hammerspoon – Lua-based powerful tool automation of macOS by beaugunderson on Sunday December 12, 2021 @08:14PM (#29535488)

One of my more useful things, cmd+shift+m and cmd+shift+u to minimize all windows and un-minimize all windows of the active application. The un-minimize gets used more often (e.g. I may have a few Chrome windows minimized during my workday that I want to un-minimize en masse after work is done).

    local cmdShift = {'cmd', 'shift'}

    hs.hotkey.bind(cmdShift, 'm', function()
      local app = hs.application.frontmostApplication()

      for _, window in pairs(app:allWindows()) do
        window:minimize()
      end
    end)

    hs.hotkey.bind(cmdShift, 'u', function()
      local app = hs.application.frontmostApplication()

      for _, window in pairs(app:allWindows()) do
        window:unminimize()
      end
    end)

Another fun thing you can do is install Hammerspoon as your URL handler, and make certain URLs open in different Chrome profiles--any work websites open in my work Chrome profile, websites related to a game I play opens in a Chrome profile specific to that, and anything else opens up in a personal Chrome profile.

I've also setup cmd+shift+1/2/3 to brings the aforementioned profiles into the foreground, so e.g. cmd+shift+2 brings my work Chrome profile to the foreground.

For anyone else trying to determine how to switch between Chrome profiles on macOS, I found a superuser post [0] In short you can run:

    open -a "Google Chrome" --args --profile-directory=$NAME

where $NAME for your current Chrome profile can be found by looking at Profile Path in chrome://version. The last directory in Profile Path is $NAME. The default $NAME is "Default" and another profile could be "Profile 5".

yup this is very similar to what I ended up with:

    -- open Chrome Canary with a specific named Profile
    function canaryWithProfile(profile, url)
      local t = hs.task.new("/Applications/Google Chrome Canary.app/Contents/MacOS/Google Chrome Canary",
      nil,
      function() return false end,
      { "--profile-directory=" .. profile, url })
      t:start()
    end

    -- open Chrome with a specific named Profile
    function chromeWithProfile(profile, url)
      local t = hs.task.new("/Applications/Google Chrome.app/Contents/MacOS/Google Chrome",
      nil,
      function() return false end,
      { "--profile-directory=" .. profile, url })
      t:start()
    end

I've wanted to send YouTube links directly to VNC for ages, while having all others open in the default browser, but have never taken the time to hack up a listener.

I already use Hammerspoon, so this should be a piece of cake to add.

Thanks for mentioning this ability!

I believe this is the implementation I based mine on: https://github.com/zzamboni/dot-hammerspoon/blob/master/init...

Interesting, I knew about cmd+option+m which does the minimizing part already. Weirdly doesn't seem to be an un-minimize shortcut though.

Yup, the existing minimize shortcut's missing twin led me to learn a bit more Lua so I could implement it :)
