Constructor Details

#initialize(keys) ⇒ Processor

Processors apply to “keys” which can be written manually in Markdown by the user, or are found in the host portion of the resource URI

IE, a Github Wiki processor would bind to the keys: “github-wiki”, or/and /github.com.*\/wiki\//

Manual keys are injected after the !include keyword: [!include github-wiki!](github.com/some-dude/wiki/Home)

  raise NotImplementedError
end

#stamp(node, uri, key) ⇒ Object

Node should be the root node that contains the embedded content, which will be stripped of all attributes and injected with new ones:

  1. data-embed-uri containing the URI of the embedded resource

  2. data-embed-src the name of the processor used for embedding

All children nodes that have an @id attribute will have that attribute removed as well.
