paperless-ngx Post-Consumption Data Extraction from Filename Script

This is a paperless-ngx post-consumption script to extract document data based on the original filename.

It was initially developed by @gulpman and posted in this discussion thread. I've made further changes, detailed below.

The script assumes the following pattern: {Date} - {Correspondent} - {Title}, and can parse the following cases:

	(function getSelectedLayerType() {
	/**
	* Gets the type of a given layer
	*
	* @param {Layer} layer Layer to check
	* @return {string} Layer type
	*/
	function getLayerType(layer) {
	switch (layer.matchName) {
	case "ADBE Vector Layer":

	// Copy string from ESTK to Windows clipboard:
	var myString = "Here is a string";
	var cmdString = 'cmd.exe /c cmd.exe /c "echo ' + myString + ' \| clip"';
	system.callSystem(cmdString);

	// This doesn't check that the selection is valid, or that it's an audio file.
	// Based on: http://stackoverflow.com/questions/21634091/is-it-possible-to-get-bitrate-of-mp3

	(function () {
	var item = app.project.selection[0];
	var duration = item.duration;
	var fileSize = item.file.length;

	var kbit = fileSize/128;
	var kbps = Math.ceil(Math.round(kbit / duration) / 16) * 16;

	function getTemplatePath () {
	if (parseFloat(app.version) < 14.0) return;

	try {
	if (app.preferences.havePref("Template Project", "Location", PREFType.PREF_Type_MACHINE_INDEPENDENT)) {
	return app.preferences.getPrefAsString("Template Project", "Location", PREFType.PREF_Type_MACHINE_INDEPENDENT);
	} else {
	throw new Error("Template Project Location preference does not exist.");
	}
	} catch(e) {

	(function () {
	/**
	* Gets currently open comp from timeline, as opposed to
	* selected comp in project panel
	*
	* @returns {CompItem \| null} Active comp, or null if none
	*/
	function getFocusedComp() {
	var activeItem = app.project.activeItem;

	// This will get the clipboard contents directly as a string
	var clipboardContents = system.callSystem("cmd /c \"for /f \"eol=; tokens=* delims= \" %I in ('powershell Get-Clipboard') do @set CLIPBOARD_TEXT=%I && echo %I\"");

	// Figuring out some math to determine aov, filmSize and focalLength in an AE camera, as these values aren't script-accessible.
	// Assuming units are pixels, film size measuring horizontally

	var comp = app.project.activeItem;
	var camera = your camera layer;

	var compSize = comp.width;
	var cameraZoom = camera.zoom;
	var depthOfField = camera.depthOfField;
	var focusDistance = camera.focusDistance;
