Select output writer for Pandoc in the YAML metablock

In order to specify an output format for pandoc, I must set the -t flag on the command line. I would like to specify which output format I want from inside of my Markdown text file. Is this possible?

For instance, if I wanted pandoc to convert my Markdown text file to a Microsoft Word document, I imagine it might look like this:

mydocument.md:

---
title: Not Just Good, More Good
author: DanielTA
date: 9 September 2022
geometry: margin=1in
mainfont: Comic Neue
fontsize: 12pt
output: docx
---

Document body text...

Then run pandoc mydocument.md which would output mydocument.docx into the same directory.

I tried this and it does not seem to work. I know that many command line variables can be defined in the YAML metablock header, but I am not sure if format/output options are possible to define there.

That should be easy to implement with lua writer using pandoc.write function.

function Writer (doc, opts)
  local fmt = doc.meta.output[1].text
  local template = pandoc.template
  opts.template = template.compile(template.default(fmt))
  return pandoc.write(doc, fmt, opts)
end

function Template ()
  return""
end

And this works as expected for most of the formats. But not with "docx".

It's not possible to define this kind of information in the metadata. However, pandoc has a feature called "defaults files". Input and output formats, options, and filenames can all be put there. The file is then passed to pandoc via --defaults or -D.

pandoc -D docx.yaml mydocument.md

Alternatively, take a look at Quarto. It is a beautiful system based on pandoc and allows to incorporate this kind of info directly in the YAML frontmatter.
