awesome window manager

Just spent a good two^Wthree hours trying to configure awesome 3.0 to match my awesome 2.x setup. Docs are effectively nonexistant. So far, I'm stuck on several fronts:

I want to be able to left click on a titlebar and drag to resize. Without pressing the modkey. But the definition for that is set deep within awful.lua, which is not a configuration file, and so I cannot see a good way to configure it.
Why can't I resize an xterm to 80 characters wide? It jumps between 79 and 81.
Why is it that despite using the same font as with 2.0, enough additional vertical space is used by the title bar and status bar, that I get one less line in all my xterms? It's using only a few pixels more than before, but that's too much..
How do I configure a textbox so that, if I click on it, a command is run? Update: Figured this one out, for example: mympd:mouse_add(mouse({ }, 1, function () os.execute("awesome-mpd show &") end)) (Note that if the command isn't run in the background, and opens a window, it will deadlock awesome.)
Can't figure out how to use awesome-client to add a value to a graph widget. (I'm sure this is simple, but I haven't stumbled over an example. I'd use wicked, but it's not packaged.) Update: Figured it out via the source: mpgraph:plot_data_add("foo", "10")
Can't figure out how to make a textbox widget have a fixed width and truncate the text in it. Since it's displaying the currently plaging song, using the default dynamic width would make everything on my status bar jump around. Update: mytextbox.width=100
There's no emptybox widget aymmore, so how do I add horizontal padding between widgets? Best I've managed so far is an empty textbox with a defined width.

Anyone else hate lua, or at least build-your-own-WM-in-lua config files for window managers that used to have simple config files?

-- press "Mod4 + b" to hide the statusbar

key({ modkey }, "b", function ()
      if mywibox[mouse.screen].screen == nil then
         mywibox[mouse.screen].screen = mouse.screen
     else
         mywibox[mouse.screen].screen = nil
     end
end):add()

-- press "Mod4 + F12" to lock the screen

key({ modkey }, "F12",

function ()
awful.util.spawn('xscreensaver-command -lock')
end):add()

-- 載入 theme 的程式庫
require("beautiful")

-- 設定使用的 theme
beautiful.init("path_to_theme_file")

-- beautiful.init 實例：可使用內建程式庫來抓設定資料夾的位置，也可簡單直接指定
beautiful.init(awful.util.getdir("config") .. "/themes/default/theme.lua")
beautiful.init("/home/USER/.config/awesome/themes/default/theme.lua")

-- 載入 ~/.config/awesome/current_theme/theme.lua

beautiful.init(awful.util.getdir("config") .. "/current_theme/theme.lua")

-- 選單函式的設定

mythememenu = {} 
function theme_load(theme) 
 local cfg_path = awful.util.getdir("config") 
 
 -- Create a symlink from the given theme to /home/user/.config/awesome/current_theme
 -- (在 /home/USER/.config/awesome/ 建立 symlink current_theme 指向
 -- /home/USER/.config/awesome/themes/THEME_NAME)
 awful.util.spawn("ln -sfn " .. cfg_path .. "/themes/" .. theme .. " " .. cfg_path .. "/current_theme") 
 awesome.restart()
end 
function theme_menu() 
 -- List your theme files and feed the menu table (列出可用的佈景主題並餵給 menu table) 
 local cmd = "ls -1 " .. awful.util.getdir("config") .. "/themes/" 
 local f = io.popen(cmd) 
 for l in f:lines() do 
 local item = { l, function () theme_load(l) end } 
 table.insert(mythememenu, item) 
 end
 f:close() 
end

-- Generate your table at startup or restart (啟動或重啟 awesome 時，產生 theme table) 
theme_menu()

-- Modify your awesome menu to add your theme sub-menu (在主選單中加入切換 theme 的項目)
myawesomemenu = { 
 { "manual", terminal .. " -e man awesome" },
 { "edit config", editor_cmd .. " " .. awful.util.getdir("config") .. "/rc.lua" },
 { "themes", mythememenu },
 { "restart", awesome.restart },
 { "quit", awesome.quit } 
}

ln -sfn /home/USER/.config/awesome/themes/THEME_NAME /home/USER/.config/awesome/current_theme
