What would you like to do?
pull down from top alacritty (like iTerm2)
window:
# Window dimensions (changes require restart)
#
# Number of lines/columns (not pixels) in the terminal. The number of columns
# must be at least `2`, while using a value of `0` for columns and lines will
# fall back to the window manager's recommended size.
dimensions:
columns: 500
lines: 30
# Window position (changes require restart)
#
# Specified in number of pixels.
# If the position is not set, the window manager will handle the placement.
position:
x: 0
y: 0
# Window padding (changes require restart)
#
# Blank space added around the window in pixels. This padding is scaled
# by DPI and the specified value is always added at both opposing sides.
#padding:
# x: 0
# y: 0
# Spread additional padding evenly around the terminal content.
#dynamic_padding: false
# Window decorations
#
# Values for `decorations`:
# - full: Borders and title bar
# - none: Neither borders nor title bar
#
# Values for `decorations` (macOS only):
# - transparent: Title bar, transparent background and title bar buttons
# - buttonless: Title bar, transparent background and no title bar buttons
decorations: none
key_bindings:
- { key: Return, mods: Command, action: ToggleSimpleFullscreen }

Thanks, this works great! I have a small addition to hide Alacritty when other apps get focus or cmd-tab is used. Put this below your code to get it working:

-- Hide alacritty if not in focus
hs.window.filter.default:subscribe(hs.window.filter.windowFocused, function(window, appName)
  local alacritty = hs.application.get('Alacritty')
  if alacritty ~= nil then
     alacritty:hide()
  end
end)

Great idea. But I will not merge this because I sometimes need to operate in other focused windows while monitoring the display of the terminal. For example, I have a long run job in the terminal, I want to reply a mail while waiting, but if there’s anything wrong, I hope I can deal with it immediately.

So I need the terminal window there even it has lost focus.

And you have given enough instruction that anyone need this feature can add it very easily. I will leave it as a comment of this gist.

Thank you for your code!

Sure, no problem, the tweak is just a matter of preference 😀

Any idea how to make alacritty always show up on the primary screen in a multimonitor setup? It seems that spaces.activeSpace() returns the currently focused space and not the primary one (contrary to what the documents say it should return). Basically I always want my term to show up on my external monitor. Thanks!

@Tylerc230 My first hacky suggestion would be something like:

  • Find the UUID of your laptop display (print("mainScreen:", spaces.mainScreenUUID()) when opening terminal on that screen should output the uuid in the Hammerspoon console)
  • Find all screenUUIDs (spaces.layout() or similar)
  • If connected to external-display, show terminal on any UUID not equal to your laptop screen uuid
  • If no connected external display show on laptop display

Good luck and give me a shout if you can't get it working, my lua skills are weak, but I can try to help if you get stuck 😀

Here's what I came up with (thanks for the help!):

  local function visiblePrimarySpace()
    local primaryScreen = hs.screen.primaryScreen()
    local primaryScreenSpaces = spaces.layout()[primaryScreen:getUUID()]
    local visibleSpaces = spaces.query(spaces.masks.currentSpaces)
    for _, ps in pairs(primaryScreenSpaces) do
      for _, vs in pairs(visibleSpaces) do  
        if ps == vs then
          return ps
        end
      end
    end
  end

Great configuration thanks!
I have one issue though, but i don't know how to fix it.
When have a full-screen app open and press the hotkey, it opens over the full-screen app as expected but immidiately takes me to the desktop (while alacritty is still over that full-screen app).
Any suggestions on fixing this?
