If you're reading this document, you're probably one of many people confused about how to implement OOP-like classes in Lua. But no worries! This document aims to explain all the fundamental concepts in beginner-friendly language.

Metatables

Before we start, we need to talk about metatables. These are Lua's way of allowing users to overload operators. Operators include arithmetic +, -, *, /, etc., but also things like indexing tables a[b], creating new indices in tables a[b] = c, function calls, a(b, c, d), you get the idea.

We can set the metatable of a table using setmetatable(t, metatable). The metatable is another table, that contains fields for overriding

This is a simple, should-be-drop-in replacement for the old /System/Library/Printers/Libraries/quartzfilter utility which went away circa OS X 10.8.

Usage:

chmod +x quartzfilter.js
./quartzfilter.js infile.pdf filter.qsfilter outfile.pdf

e.g.,

./quartzfilter.js my-big-pdf.pdf "/System/Library/Filters/Reduce File Size.qfilter" my-less-big-pdf.pdf

	defmodule TravelerWeb.SearchbarLive do
	use TravelerWeb, :live_view

	alias Phoenix.LiveView.JS
	alias Traveler.Places

	def mount(_params, _session, socket) do
	socket = assign(socket, places: [])
	{:ok, socket, layout: false}
