请求增加获取系统毫秒时间戳的api

[Urie96]

我想实现一个快速连按两下冒号输出:=的lua_processor，但是似乎现在无法从lua中获取毫秒时间戳，请问有办法实现吗

[shewer]

可以用 os.clock() 每次 processor::processorkeyevent() 時 記錄時間()

function P.init(env)
   env.timestmp = os.clock()
end

function P.func(key, env)
    local stmp = os.clock()
    local ltime = stmp - env.timestmp
    env.timestmp = stmp

     ......
end

return P

忘了說明processorKeyEvent() 是 包含 Release 的 按下 a 鬆開 a 按下 a 所以 刷新 timestmp 機制 要調整一下

Shift+Release+F12 Shift+Release+Shift_L a Release+a b Release+b c Release+c d Release+d e Release+e f Release+f g Release+g g g g g g g g g g g g g g g g g Release+g Shift_L

發覺我錯了 os.clock() 用不了

你可以用luarocks 裝 socket 裏頭有 gettime() 可以用

[shewer]

需要 luasocket 的gettime()
