This is an additional concept to markdown, where you can inject your custom tags to parse. All tags must be an instance
of luya\tag\BaseTag and implement the parse($value, $sub) method in order to convert the input to your tag.
Read more in the Guide [[concept-tags.md]].
The identifier of the tag is not related to your tag, so you can configure the same tag as different names with multiple
purposes.
To inject a created tag just use:
php
TagParser::inject('tagname', ['class' => 'path\to\TagClass']);
To parse text with or without markdown use:
php
TagParser::convert('Hello tagnamevalue');
TagParser::convertWithMarkdown('**Hello** tagnamevalue');
