Re: Timeout on stdin

["Xu Wang" <xu4wang@...>]

Hi Jim,

I was searching for a solution but failed weeks ago. I workaround this by using LuaTask(threads).

One thread using Luasocket in asychronized mode and read it's queue when no data from the network, another thread reading the lua io.

Here is a small demo for the idea
----------------------------------------------------------------------------main.lua-------------------------------------------
local socket = require("socket")
require"task"

local tsk = task.create( "cli_get_input.lua" )
host = host or "localhost"
port = port or 9999
if arg then
    host = arg[1] or host
    port = arg[2] or port
end
host = socket.dns.toip(host)
tcp = assert(socket.tcp())
assert(tcp:setpeername(host, port))
print("Using remote host '" ..host.. "' and port " .. port .. "...")
tcp:settimeout(0.1)
while 1 do
    --receive stdio input from another task
    line,flag,rc=task.receive(10)
    
    if rc==0 then
        tcp:send(line.."\n")
    end
    
    dgram = tcp:receive()
    if dgram then 
        print(dgram)
    end
end

-----------------------------------------------------cli_get_input.lua-----------------------------------------

print"CLI running..."

while 1 do
    line=io.read()
    task.post(1,line,0)
end
