What frontmatter formats does the editor support?

The editor supports YAML frontmatter delimited by --- markers, which is the standard format used by Hugo, Jekyll, Gatsby, Next.js, Docusaurus, and most static site generators.

Can it handle complex YAML values like arrays and objects?

Yes, array values can be entered as JSON (e.g., ["tag1", "tag2"]) and will be properly serialized back to YAML. Nested objects are displayed as JSON strings that can be edited.

Does it preserve my markdown content?

Yes, the editor only modifies the frontmatter section. All markdown content below the frontmatter closing --- is preserved exactly as entered.

What is the gray-matter library?

Gray-matter is a popular open-source Node.js library for parsing and stringifying frontmatter in markdown files. It's used by many static site generators and documentation tools.

Is my content private during editing?

Yes, all parsing and editing happens entirely in your browser. No data is sent to any server, ensuring complete privacy for your documents.
