Story: Writing Scripts with Go

This is a story about how I tried to use Go for scripting. In this story, I’ll discuss the need for a Go script, how we would expect it to behave and the possible implementations; During the discussion I’ll deep dive to scripts, shells, and shebangs. Finally, we’ll discuss solutions that will make Go scripts work.

Why Go is good for scripting?

While python and bash are popular scripting languages, C, C++ and Java are not used for scripts at all, and some languages are somewhere in between.

HTTP Streaming (or Chunked vs Store & Forward)

The standard way of understanding the HTTP protocol is via the request reply pattern. Each HTTP transaction consists of a finitely bounded HTTP request and a finitely bounded HTTP response.

However it's also possible for both parts of an HTTP 1.1 transaction to stream their possibly infinitely bounded data. The advantages is that the sender can send data that is beyond the sender's memory limit, and the receiver can act on

	#!/bin/bash

	DIR="$( cd "$( dirname "${BASH_SOURCE[0]}" )" && pwd )"
	usage="usage: $(basename "$0") [-h] [-r] [-s] [-t] -n name
	options:
	-n name Name of JAR (including .jar extension)
	-r restart Restart jar once deployed
	-t target Set target, for instance demo1
	-s SSH target Set SSH target, for instance -s usr@my_host -t /home/usr/remote/dir/path
	-h [help]
