Pen
Pen is a visual WYSIWYG markdown editor and live editing interface that converts markdown patterns into rich text elements in real-time. It serves as a tool for markdown content authoring and transforming editor state into standard markdown strings for export.
The editor features a customizable text interface with a formatting toolbar for text-styling actions. It includes systems for hyperlink management and the automatic conversion of specific character sequences into structured headings, lists, blockquotes, and code blocks during the input process.
