NodeMCU - Avoid the system hanging from infinite loop and run TCP Server after getting IP

I was trying to develop my NodeMCU as a controller for Home Automation,
Once I found searching for wifi in loop ended in an infinite loop and hence I have to FLASH the firmware, and reload it. To avoid the same in future I did teh following

The best solution i found is create a delay of some seconds before starting the infinite loop, so that when system has to be reset, you will enough time to do it.

Some tutorials is here : http://www.esp8266.com/viewtopic.php?f=18&t=1705

From the above link Setting wifi delay is done as follows.

--Startup file It is trying to connect my mobile Wifi--
SSID =   "AndroidAP"
PWD  =    "csnv6345"
HTTPServerFile = "ServerFile.lua"
    wifi.setmode(wifi.STATION)
    wifi.sta.config(SSID, PWD)
    print("Wait 5 seconds please")
    tmr.alarm(1, 5000, 1, function() -- Infinite Loop for keep checking the wifi status in a 5s delay.
        if(wifi.sta.status() ==5) then  -- Once the IP is set, stoping the timer and executing the file.
            tmr.stop(1)
            dofile(HTTPServerFile)
        end
    end)
print("End of startup")

A Sample Server file, which on the LED on first request and off on next. to test the Wifi Connection

lighton=0
pin=0
srv=net.createServer(net.TCP)
srv:listen(80,function(conn)
    conn:on("receive",function(conn,payload)
        print(payload)
         if lighton==0 then
            lighton=1
            gpio.write(pin,gpio.HIGH)
        else
            lighton=0
             gpio.write(pin,gpio.LOW)
        end
    end)
end)

How to customise code Autocompletion in ace editor.

It is easy to customize the code completion in the ace editor,
The following code will do the autosuggestion in the editor.

 editor = ace.edit("editor")
  editor.setOptions({
    // mode: "ace/mode/javascript",
    enableBasicAutocompletion: true
  });
  editor.completers.push({
    getCompletions: function(editor, session, pos, prefix, callback) {
      callback(null, [
        {value: "foo", score: 1000, meta: "custom"},
        {value: "bar", score: 1000, meta: "custom"}
      ]);
    }
  })

But the above code will do autosuggestion with the completion we have provided with the words available in the editor, 

This code is done in the ace/ext/language_tools.js




You can customize the TextCompleter in the file language_tools.js 

In line no 70 if you remove the textCompletor, you can complete control according to your recommendation.

example

 var completers = [snippetCompleter,  keyWordCompleter];//textCompleter
