Proof of concept for a simple widget to pull data from a web page

https://photos.app.goo.gl/7Fti8xcEfJkqYqjm9

sample server data that outputs data from my computer is below

<?php
$sensorsStr = shell_exec('/usr/bin/sensors -j');
$sensors = json_decode($sensorsStr, true);

$uptimeOutput = shell_exec('uptime');
if (preg_match('/^\s*(..:..:..) up (.*),  ([0-9]+ users),  load average: ([0-9.]+), ([0-9.]+), ([0-9.]+)$/', $uptimeOutput, $output)) {
	$time = $output[1];
	$uptime = preg_replace('/, /', " ", $output[2]);
	$load1min = $output[4];
	$load5min = $output[5];
	$load15min = $output[6];
}

$output = array(
	array(
		'label' => 'CPU',
		'data' => $sensors['coretemp-isa-0000']['Package id 0']['temp1_input'],
	),
	array(
		'label' => 'PNY NVME',
		'data' => $sensors['nvme-pci-0200']['Composite']['temp1_input'],
	),
	array(
		'label' => 'WD Blue NVME',
		'data' => $sensors['nvme-pci-0300']['Composite']['temp1_input'],
	),
	array(
		'label' => 'Uptime',
		'data' => $uptime,
		'labelColor' => 'blue',
		'color' => 'red',
		'background' => 'silver',
	),
	array(
		'label' => 'Load 1 min',
		'data' => $load1min,
		'color' => 'green',
		'labelColor' => 'dArK Green',
	),
);

header('Content-Type: application/json; charset=utf-8');
print json_encode($output) . "\n";

This is the json from the php script

  {
    "label": "CPU",
    "data": 48
  },
  {
    "label": "PNY NVME",
    "data": 44.85

    "label": "WD Blue NVME",

I am thinking I should create a "data class" to store the above items as they all go together. and it would be a lot cleaner.

We are going to need to build a config option to order the widgets or disable unwanted ones soon.

This should probably be in a global library as it seems like it will be useful for multiple widgets.

I think I am liking "fingerprint" more than "stamp" as I did in weatherWidget. Thoughts?

we should also check the string for newlines and break them up. But with variable font sizes x,y positioning becomes tricky
