How do I use bat script as Chrome Native Messaging Host?

I know what the first response will be but my requirement is minimal and writing a script for that would be an overkill. All I want is to run a system command and send its output to the extension.
Here is what I have tried

@echo off
:strt
:: my code
goto strt

Doesn't work. The above code give me an error message Error when communicating with the native messaging host.

Following example Here

It turns out that .bat doesn't fulfil requirements for chrome native messaging host . My requirement from host was simple and using either python or c++ would be too much.I have opted for powershell to accomplish the task.

here is the powershell version

try {
$reader = New-Object System.IO.BinaryReader([System.Console]::OpenStandardInput())
$len = $reader.ReadInt32()
$buf = $reader.ReadBytes($len)
$msg = [System.Text.Encoding]::UTF8.GetString($buf)

$nets = ConvertFrom-Csv (getmac /fo CSV /v)
..
..
..
# you get the point.
Response @{mac = $mac} }

Answering my own question and hoping it would help someone in future.
