12.5 style custom resources

This is by far the most recommended way of writing resources for all users. There are two gotchas which we're working through:

For helper functions that you used to write in your provider code or used to mixin to your provider code, you have to use an action_class do ... end block.

FWIW: I (@rondy) am not the creator of the content shared here, which is an excerpt from Edmond Lau's book. I simply copied and pasted it from another location and saved it as a personal note, before it gained popularity on news.ycombinator.com. Unfortunately, I cannot recall the exact origin of the original source, nor was I able to find the author's name, so I am can't provide the appropriate credits.

Learn Go in ~5mins

This is inspired by A half-hour to learn Rust and Zig in 30 minutes.

Basics

Your first Go program as a classical "Hello World" is pretty simple:

First we create a workspace for our project:

	#!/bin/bash

	####
	# Split MySQL dump SQL file into one file per table
	# based on http://blog.tty.nl/2011/12/28/splitting-a-database-dump
	####

	if [ $# -lt 1 ] ; then
	echo "USAGE $0 DUMP_FILE [TABLE]"
	exit

	var page = require('webpage').create(),
	address, output, size;

	if (phantom.args.length < 2 \|\| phantom.args.length > 3) {
	console.log('Usage: rasterize.js URL filename');
	phantom.exit();
	} else {
	address = phantom.args[0];
	output = phantom.args[1];
	page.viewportSize = { width: 1280, height: 1024 };

	#!/bin/sh
