Awesome WM config files including

Hi.

I'm not sure if it is ok to ask about this things here so tell me if it is not smile . I have no idea where else to ask.

I have problem with Awesome WM. I try to separate rc.lua into different files (because is starts to be long) and just load them in rc.lua.

I have function for changing xrandr layout:

-- Xrandr settings switcher -- 
-- Get active outputs
local function outputs()
   local outputs = {}
   local xrandr = io.popen("xrandr -q")
   if xrandr then
      for line in xrandr:lines() do
	 output = line:match("^([%w-]+) connected ")
	 if output then
	    outputs[#outputs + 1] = output
	 end
      end
      xrandr:close()
   end

   return outputs
end

local function arrange(out)
   -- We need to enumerate all the way to combinate output. We assume
   -- we want only an horizontal layout.
   local choices  = {}
   local previous = { {} }
   for i = 1, #out do
      -- Find all permutation of length `i`: we take the permutation
      -- of length `i-1` and for each of them, we create new
      -- permutations by adding each output at the end of it if it is
      -- not already present.
      local new = {}
      for _, p in pairs(previous) do
	 for _, o in pairs(out) do
	    if not awful.util.table.hasitem(p, o) then
	       new[#new + 1] = awful.util.table.join(p, {o})
	    end
	 end
      end
      choices = awful.util.table.join(choices, new)
      previous = new
   end

   return choices
end

-- Build available choices
local function menu()
   local menu = {}
   local out = outputs()
   local choices = arrange(out)

   for _, choice in pairs(choices) do
      local cmd = "xrandr"
      -- Enabled outputs
      for i, o in pairs(choice) do
	 cmd = cmd .. " --output " .. o .. " --auto"
	 if i > 1 then
	    cmd = cmd .. " --right-of " .. choice[i-1]
	 end
      end
      -- Disabled outputs
      for _, o in pairs(out) do
	 if not awful.util.table.hasitem(choice, o) then
	    cmd = cmd .. " --output " .. o .. " --off"
	 end
      end

      local label = ""
      if #choice == 1 then
	 label = 'Only <span weight="bold">' .. choice[1] .. '</span>'
      else
	 for i, o in pairs(choice) do
	    if i > 1 then label = label .. " + " end
	    label = label .. '<span weight="bold">' .. o .. '</span>'
	 end
      end

      menu[#menu + 1] = { label,
			  cmd,
                          "/usr/share/icons/Tango/32x32/devices/display.png"}
   end
   return menu
end

-- Display xrandr notifications from choices
local state = { iterator = nil,
		timer = nil,
		cid = nil }
local function xrandr()
   -- Stop any previous timer
   if state.timer then
      state.timer:stop()
      state.timer = nil
   end

   -- Build the list of choices
   if not state.iterator then
      state.iterator = awful.util.table.iterate(menu(),
					function() return true end)
   end

   -- Select one and display the appropriate notification
   local next  = state.iterator()
   local label, action, icon
   if not next then
      label, icon = "Keep the current configuration", "/usr/share/icons/Tango/32x32/devices/display.png"
      state.iterator = nil
   else
      label, action, icon = unpack(next)
   end
   state.cid = naughty.notify({ text = label,
				icon = icon,
				timeout = 4,
				screen = mouse.screen, -- Important, not all screens may be visible
				font = "Free Sans 18",
				replaces_id = state.cid }).id

   -- Setup the timer
   state.timer = timer { timeout = 4 }
   state.timer:connect_signal("timeout",
			  function()
			     state.timer:stop()
			     state.timer = nil
			     state.iterator = nil
			     if action then
				awful.util.spawn(action, false)
			     end
			  end)
   state.timer:start()
end

I save it as xrandr.lua and paste it into folder awesome/rc.

Then I have function in rc.lua for loading files from "rc" folder (from here: https://github.com/vincentbernat/awesom … /rc.lua#L8 ):

function loadrc(name, mod)
   local success
   local result

   -- Which file? In rc/ or in lib/?
   local path = awful.util.getdir("config") .. "/" ..
      (mod and "lib" or "rc") ..
      "/" .. name .. ".lua"

   -- If the module is already loaded, don't load it again
  if mod and package.loaded[mod] then return package.loaded[mod] end

   -- Execute the RC/module file
   success, result = pcall(function() return dofile(path) end)
   if not success then
      naughty.notify({ title = "Error while loading an RC file",
		       text = "When loading `" .. name ..
			  "`, got the following error:\n" .. result,
		       preset = naughty.config.presets.critical
		     })
      return print("E: error loading RC file '" .. name .. "': " .. result)
   end

   -- Is it a module?
   if mod then
      return package.loaded[mod]
   end

   return result
end

Then I pasted ' loadrc("xrandr") ' into my rc.lua, but nothing happens. I tried different folders (for example simple widget and then loadrc this widget file), but all I get is just pack of errors.

I also tried just: "require("xrandr")" but still the same.


Thanks for help
