Awesome WM vocabulary widget
換到 awesome wm 之後,上方的 bar 其實有很多空間。因為自己的記性不好,乾脆寫個小 widget,大約 60 秒就 show 一個單字,不然每次五十音我都會一直忘記抄抄寫寫一堆很醜的 lua code 的結果如下,他會讀取 .vocabulary 這個檔案,每 60 秒亂數取其中一行顯示
檔案更新怎麼辦?重開一下 awesome 就好囉!
vocabulary_widget = widget({ type = "textbox" })
function vocabularyUpdate(lines)
vocabulary_widget.text = lines[math.random(0, #lines)]
end
function readFile(filename)
local arr = {}
local i = 0
local file=io.open(filename, "r")
if not file then return "empty" end
for line in file:lines() do
arr[i] = line
i = i + 1
end
return arr
end
local file = "/home/walkingice/.vocabulary"
local period = 60
math.randomseed(os.time())
content = readFile(file)
vocabulary_timer = timer({timeout = period})
vocabulary_timer:add_signal("timeout", function() vocabularyUpdate(content) end)
vocabulary_timer:start()
