lua program shows current time

This is a piece of lua script that displays the time. I cannot separate the numbers ie: time.hour, ":", to basically show hh:mm:ss 

time = os.date("*t")
print(time.hour .. time.min .. time.sec)
Solution

  • There are several ways to do this:

    1. Use string concatenation: print(time.hour .. ":" .. time.min .. ":" .. time.sec)

    2. Use formatting: print(("%02d:%02d:%02d"):format(time.hour, time.min, time.sec))

    3. Use table concatenation: print(table.concat({time.hour, time.min, time.sec}, ":"))

    When you really need to format your string, my preference would be for #2. For time = {hour = 1, min = 20, sec = 5} this prints:

    1:20:5
01:20:05
1:20:5
