I want to create an HTML file to play that video with subtitles, all from the local filesystem.

Problem

Should be work with 0.18

Destructuring(or pattern matching) is a way used to extract data from a data structure(tuple, list, record) that mirros the construction. Compare to other languages, Elm support much less destructuring but let's see what it got !

Tuple

myTuple = ("A", "B", "C")
myNestedTuple = ("A", "B", "C", ("X", "Y", "Z"))

	#!/bin/bash

	# You'll need to have sox, pavucontrol and alsa-utils installed, and the snd_aloop kernel module loaded.
	# You can configure your system to load it on startup or load it manually with "sudo modprobe snd_aloop"

	# Once this is script is running, you need to start recording audio in the application of your
	# preference, open pavucontrol, go to the recording tab and change the recording source of that application
	# to "Monitor of Loopback ..."
