Ask your question!

I went through the documentation but couldn't find the answer. I want the new WezTerm window to immediately take on a specified size and be centered on the screen. How can I achieve this?

wezterm.on("gui-startup", function(cmd)
	local screen = wezterm.gui.screens().main
	local ratio = 0.7
	local width, height = screen.width * ratio, screen.height * ratio
	local tab, pane, window = wezterm.mux.spawn_window(cmd or {
		position = { x = (screen.width - width) / 2, y = (screen.height - height) / 2 },
	})
	-- window:gui_window():maximize()
	window:gui_window():set_inner_size(width, height)
end)

Here's a slightly modified version to make WezTerm window appear on the currently active screen:

wezterm.on("gui-startup", function(cmd)
  local screen            = wezterm.gui.screens().active
  local ratio             = 0.7
  local width, height     = screen.width * ratio, screen.height * ratio
  local tab, pane, window = wezterm.mux.spawn_window {
    position = {
      x = (screen.width - width) / 2,
      y = (screen.height - height) / 2,
      origin = 'ActiveScreen' }
  }
  -- window:gui_window():maximize()
  window:gui_window():set_inner_size(width, height)
end)

When there is a high-resolution screen, cols = 100, rows = 35, otherwise based on the screen percentage (1920 * 0.65, 1080 * 0.80)

wezterm.on("gui-startup", function(window)
  local screen            = wezterm.gui.screens().active
  if screen.width == 1920 and screen.height == 1080 then
    local width, height     = screen.width * 0.65, screen.height * 0.80
    local tab, pane, window = wezterm.mux.spawn_window {
      position = {
        x = (screen.width - width) / 2,
        y = (screen.height - height) / 2,
        origin = 'ActiveScreen'
      }
    }
    -- window:gui_window():maximize()
    window:gui_window():set_inner_size(width, height)
  end
end)

Add it anywhere according to your configuration

  config.initial_cols = 100
  config.initial_rows = 35
