Kramdown Prismic

A Kramdown parser and converter to convert documents into prismic rich text format and the other way around.

A useful usage is to convert markdown documents to prismic for import purpose. Then you can even convert prismic format back to markdown.

Status

The converter part (kramdown to prismic) is working and fairly complete. See Difference between markdown and rich text below to know more about limitations.

The parser part is quite new and not feature complete.

Lookup for warnings

For instance, html elements in the markdown is not supported:

markdown = '<h1>Hello world</h1>'
result = Kramdown::Document.new(markdown, input: :markdown)
result.to_prismic
p result.warnings
