How to create/preserve a frontmatter in Markdown/GFM output?

[mavam]

I'd like to know if I can include and/or preserve a YAML frontmatter in the Markdown and GFM output.

Use case: I'd like to use a Quarto notebook as blog post. The blogging platform takes GFM as input (Docusaurus). The blog post meta data is in a YAML frontmatter.

Workaround: concatenate the desired YAML frontmatter from an external file. This is suboptimal, as it breaks the self-containment and requires extra build scaffolding.

Desired functionality: provide a flag to quarto build that preserves the YAML frontmatter, or a subset thereof.

I should have taken a closer look at the docs. Via projects, adding this to _quarto.yml does the job:

format:
  gfm:
    keep-yaml: true

Any *.qmd files now keep the YAML frontmatter intact.

Thanks for the follow-up.
