Integrate Aersoapce tiling manager in sketchybar

[bassamsdata]

Hello,

I've started using a new performant tiling manager called Aerospace, and I'm replacing Amethyst with it. However, I haven't been able to fully integrate it into SketchyBar. I'm using Lua and was able to display the workspaces, but I haven't been able to get them to update.

If anyone has Aerospace configured and could share their config, it would be greatly appreciated.

thank you

here is my config:

local colors = require("colors")
local settings = require("settings")
local app_icons = require("icons")

local function lines(str)
	local result = {}
	for line in str:gmatch("[^\n]+") do
		table.insert(result, line)
	end
	return result
end

local function icons_for_apps(app_names)
	local icon_line = {}
	for _, app in pairs(app_names) do
		local lookup = app_icons[app]
		local icon = ((lookup == nil) and app_icons["Default"] or lookup):gsub("iterm", "terminal")
		table.insert(icon_line, icon)
	end
	return icon_line
end


sbar.exec("aerospace list-windows --all --format '%{workspace} %{app-name}'", function(all_workspaces)
	local aerospaces = lines(all_workspaces)

	local spaces = {}

	for i, sid in pairs(aerospaces) do
		local space_name = "space." .. sid
		local space = sbar.add("item", space_name, {
			icon = {
				font = { family = settings.font.numbers },
				string = sid,
				padding_left = 15,
				padding_right = 8,
				color = colors.white,
				highlight_color = colors.red,
			},
			label = {
				padding_right = 20,
				color = colors.grey,
				highlight_color = colors.white,
				font = "sketchybar-app-font:Regular:16.0",
				y_offset = -1,
			},
			padding_right = 1,
			padding_left = 1,
			background = {
				color = colors.bg1,
				border_width = 1,
				height = 26,
				border_color = colors.black,
			},
			popup = { background = { border_width = 5, border_color = colors.black } },
		})
		if sid ~= nil then
			spaces[sid] = space
		end

		space:subscribe("aerospace_workspace_change", function(env)
			selected = env.FOCUSED_WORKSPACE == sid
			space:set({ background = { drawing = selected } })
		end)

		space:subscribe("space_windows_change", function(env)
			-- run window change events only on first item, since aerospace places everyting on a single space and this events get's triggered for every item
			local is_first = env.NAME == "space.1"
			if is_first == true then
				icons_for_apps(spaces)
			end
		end)
	end
	icons_for_apps(spaces)
end)

Here is a minimal snippet that shows all aerospace workspaces in lua:

local colors = require("colors")

function parse_string_to_table(s)
  local result = {}
  for line in s:gmatch("([^\n]+)") do
    table.insert(result, line)
  end
  return result
end

local file = io.popen("aerospace list-workspaces --all")
local result = file:read("*a")
file:close()

local workspaces = parse_string_to_table(result)
for i, workspace in ipairs(workspaces) do
  local space = sbar.add("item", "space." .. i, {
    icon = {
      string = workspace,
      color = colors.white,
      highlight_color = colors.red,
    },
    label = { drawing = false },
    padding_left = 1,
    padding_right = 1,
  })

  space:subscribe("aerospace_workspace_change", function(env)
    local selected = env.FOCUSED_WORKSPACE == workspace
    space:set({
      icon = { highlight = selected, },
      label = { highlight = selected },
      background = { border_color = selected and colors.white or colors.bg2 }
    })
  end)
end

Using shell scripts is also possible and nicely detailed here: https://nikitabobko.github.io/AeroSpace/goodness#show-aerospace-workspaces-in-sketchybar

Dont forget to add the event to aerospace.toml:

# Notify Sketchybar about workspace change
exec-on-workspace-change = ['/bin/bash', '-c',
    'sketchybar --trigger aerospace_workspace_change FOCUSED_WORKSPACE=$AEROSPACE_FOCUSED_WORKSPACE'
]

Displaying the current window application icons for each aerospace workspace is not robustly possible, because some events for that are missing, see: nikitabobko/AeroSpace#316
