type DataDisplayer ¶

type DataDisplayer interface {
	JavaScript(s string, id *string)
	HTML(s string, id *string)
	Markdown(s string, id *string)
	Latex(s string, id *string)
	SVG(s string, id *string)
	PNG(b []byte, id *string)

	Text(s string, id *string)
}

DataDisplayer is the interface that wraps Jupyter Notebook display_data protocol. The list of supported content types are based on Jupyter Notebook implementation[2]. Each method receives a content and an display id. If id is nil, the method does not use id. If id is not nil and it points an empty string, the method reserves a new display ID and stores it to id. If id is not nil and it points a non-empty string, the method overwrites a content with the same ID in Jupyter Notebooks.
