How do I change the part numbers in a PDF?

Description

I have a Quarto document that contains 4 sections in response to a required template. The template includes the following parts:

• Part I: Signatures Attesting to Integrity
• Part II: Institutional Summary Form Prepared for Commission Reviews
• Part III: Fifth-Year Compliance Certification
• Part IV: Follow Up Report (Not applicable for first submission)
• Part V: Impact Report of the Quality Enhancement Plan

Right now I am doing the following in my _quarto.yml:

book:
  chapters:
    - index.qmd
    - part: "Signatures Attesting to Integrity" 
      chapters: 
        - Signatures.qmd
    - part: "Institutional Summary Form Prepared for SACSCOC Reviews"
      chapters: 
        - Summary.qmd
    - part: "Requirements"
      chapters: 
        - ... this has all the requirements
      
    - part: "Focused Report" # I DON'T WANT THIS PART
      chapters: 
        - Focused-Report.qmd
        
    - part: "Impact Report of the Quality Enhancement Plan"
      chapters: 
        - QEP-Impact-Report.qmd

format:
  pdf:
    documentclass: scrreport

I would like to construct my document such that it skips Part IV as that is not applicable at this point. Is there some way to do this via the configuration, header options in the part files, or in a Lua script?

Thanks,
David

Please provide a fully reproducible example or at least a complete one. For instance, you did not provide the format.

[dmonder]

Updated to include the format section. I can work on a reproducible example, but I need to extract it from my actual work sample which is much larger and includes many more options for our final product.

[mcanouil]

If your target is LaTeX/PDF, then use LaTeX command for instance in include-in-header, such as something like \renewcommand{\thepart}{\Roman{part}}.

Example:

format:
  pdf:
    documentclass: scrreprt
    include-in-header:
      - text: |
          \renewcommand{\thepart}{\arabic{part}}

I am not wanting to change the number type. I want to have it include parts I, II, III, and V, but skip IV. I want to specify the following:

book:
  chapters:
    - index.qmd
    - part: "Signatures Attesting to Integrity"   # This is Part I
      chapters: 
        - Signatures.qmd
        - 
    - part: "Institutional Summary Form Prepared for SACSCOC Reviews"  # This is Part II
      chapters: 
        - Summary.qmd
        - 
    - part: "Requirements"  # This is Part III
      chapters: 
        - ... this has all the requirements
      
    - part: "Impact Report of the Quality Enhancement Plan"  # This is Part V
      chapters: 
        - QEP-Impact-Report.qmd

format:
  pdf:
    documentclass: scrreport

And get a PDF that numbers them as Part I, II, III, and V.

You need to insert a LaTeX command to increase the counter at the end of the previous part then.
See https://quarto.org/docs/authoring/markdown-basics.html#raw-content.

OK. That works. Any idea how I can inject that before part V instead of inserting it at the end of the previous part? There are different files that can end up being the previous file. I already have a Lua filter processing other parts of the input. I can just add a section that looks for "parts" and inserts that LaTeX code before it. I just have no idea what to trigger the filter on.

[dmonder]

I figured that part out. I capture headers and inspect for a header 1 with the content of the part and replace it with a RawInline:

Something like:

local filter = {
    Header = function(el)
        if (el.level == 1) then
            if quarto.doc.is_format("pdf") and pandoc.utils.stringify(el.content) == "Impact Report of the Quality Enhancement Plan" then
                el = pandoc.RawInline("latex", "\\setcounter{part}{4} % From Lua\n\\part{Impact Report of the Quality Enhancement Plan}")
            end
        end
        return el
    end
}

Now I just need to turn them into parameters and all will be well!

Thank you for your help!
