// The purpose of this file is to deserialize markdown examples
// to WYSIWYG HTML and to prosemirror documents in JSON form, using
// the logic implemented as part of the Content Editor.
//
// It reads an input YAML file containing all the markdown examples,
// and outputs a YAML files containing the rendered HTML and JSON
// corresponding each markdown example.
//
// The input and output file paths are provides as command line arguments.
//
// Although it is implemented as a Jest test, it is not a unit test. We use
// Jest because that is the simplest environment in which to execute the
// relevant Content Editor logic.
//
// This script should be invoked via jest with the a command similar to the following:
// yarn jest --testMatch '**/render_wysiwyg_html_and_json.js' ./scripts/lib/glfm/render_wysiwyg_html_and_json.js
