The following method prepare the synopsis from the body and the second part is for unit tests:

	/**
	* Returns short synopsis
	* @param $bodyString Body string
	* @return string|null
	*/
	public function getSynopsis($bodyString): ?string
	{
	if (null === $bodyString) {
	return null;
	}
	$matchFound = (
	\preg_match(
	'/(<li>\s*(.*?)\s*<\s*\/li>)/mu',
	$bodyString,
	$matches
	)
	);
	if (0 < $matchFound) {
	return \strip_tags(
	\trim(
	\current($matches)
	)
	);
	}
	return (
	\strip_tags(
	\trim(
	\current(
	\preg_split('/^\s?\W\s+/mu', $bodyString, 2, \PREG_SPLIT_NO_EMPTY)
	)
	)
	)
	?? $bodyString

Fix for ng serve --watch is not watching for code changes in Ubuntu

I was running the Angular 8 application on Ubuntu LTS 18.04 on my machine and was having an issue to refresh on code update using  --watch.

Trying to use ng serve and ng build --watch was not watching for code changes and I thought it was something to do with node or angular-cli.

However, I found the solution on Github (https://github.com/angular/angular-cli/issues/8313)

I ran the following on Terminal and apparently, it worked and watching code changes:

echo fs.inotify.max_user_watches=524288 | sudo tee /etc/sysctl.d/40-max-user-watches.conf && sudo sysctl --system

Hope this helps!
