Hello @tunnelshade, thank you for your interest in our work!

Unfortunately @tunnelshade yaml frontmatter is not supported right now. Could you detail why you want it supported and what is your exact use case ? I assume you are working with Jekyll ?

[flabbergastedbd]

I use zola but underlying pattern is markdown frontmatter. Support for Yaml or Toml frontmatter will be awesome as it is common across most of static site generators.

[jb-delafosse]

So for the sample.md you posted earlier, the title is given in the YMF section of the document. Your usecase is you want to index your documents based on the title given in this section.

How would you reference sample.md in another file ? And what would be your workflow using linky-note ? Apply Linky note, then apply static site generation I assume.

• Links are only via filename. If title is not required for anything else (like adding in backlinks) then lack of a title can be ignored when reference_by: filename.
• [Link](./sample.md) is the way files are referenced.
• Workflow is apply linky note and generate static site. 💯
