Have intext citations that link to PDFs stored in Zotero

Link to PDF from intext / inline citation instead of to bibliography

Sorry if this isn't really a Quarto thing. I'm in the process of writing my thesis, and I really like how Quarto has made me focus more on writing than formatting (cuz I made a template for my thesis), while usingg rbbt to link to Zotero and make my citations and bibliography.

I think that it'd be very helpful to share my manuscript alongside the PDF files, so that when someone is reading the manuscript, they can click on the intext citation and it'd take them to the PDF (or maybe even at a specific page or selection).

It's very difficult somehow to see this asked in the internet, but I found this: (Link to PDF from citation in Docs?), and it's pretty much the most similar to my desired feature.

I think this can be done by duplicating and storing all the reference PDFs in a folder, and have the Quarto intext citation reference that PDF. Then the exported manuscript and the PDF folder can be shared together to allow readers to also see the sources themselves. This would be really helpful when multiple people need to check each other's work, like my adviser reading my manuscript.

You can write a LUA filter.
Something like the example below will add a DOI link after the citation if the reference contains a DOI:

local references = {}

function get_references(doc)
  references = pandoc.utils.references(doc)
  return doc
end

function process_citations(elem)
  local cite_id = elem.citations[1].id
  
  -- Find the reference by ID
  local ref = nil
  for _, reference in ipairs(references) do
    if reference.id == cite_id then
      ref = reference
      break
    end
  end
  
  if ref and ref.DOI then
    local doi_text = pandoc.utils.stringify(ref.DOI)
    local doi_url = "https://doi.org/" .. doi_text
    local doi_link = pandoc.Link({pandoc.Str("DOI")}, doi_url)
    return {elem, pandoc.Str(" "), doi_link}
  end
  
  return elem
end

return {
  { Pandoc = get_references },
  { Cite = process_citations }
}

You would need this filter to come after Quarto's processing.

filters:
  - path: citation.lua
