Strikethrough and CommonMarker::Node initialization

[paydaylight]

Are there any ways of initializing just a strikethrough node?

Like:

CommonMarker::Node.new(:strikethrough)

From docs I know that I can pass to constructor types supported out of the box, but not ones that are from extensions.

If I'm understanding your question correctly, no, there is not. You can iterate over a document or take different actions when rendering, but you cannot just add nodes that aren't already present in the commonmark source text.
