Hello,
in order to maintain typographic rules for my language I have to use a custom parser for all content. The parser is simple and as such, works fine. It extends TextParser and then is called in templates with $Content.Parse(MyParser).

However, this stops shortcodes from working. Apparently using a custom parser turns off the ShortcodeParser. So how do I use a custom parser without losing shortcodes?

I searched the forums for answers, and the same question was apparently asked 3 years ago here, but was unresolved.

This is because the HTML ShortcodeParser is invoked in the forTemplate() method of the HTMLText object.

$Content is a HTMText object so it gets shortcodeparsed.

$Content.Parse(MyParser) is whatever the MyParser::parse() function returns. So if that returns a string, nothing further will happen. Returning a HTMLText object instead will fix this:

class MyParser extends TextParser {
	
	public function parse() {

		//create some content
		$content = $this->content . "*****************";
		
		//return as a HTMLText object
		return DBField::create_field('HTMLText', $content);
		
	}
}

A late but due thanks, martimiz, this worked perfectly.
