Adding new custom properties into template-partials (i.e. supervisor to the page title)

[danieltomasz]

Description

I found serveral discussion about partials, but nowhere I cannot find how to pass new custom propereties to partials. I want to modify only the titlepage in the book project how can I correctly pass it with minimal changes/code boilerplate?

My example title.tex:

$if(title)$
\title{$title$$if(thanks)$\thanks{$thanks$}$endif$}
$endif$

$if(subtitle)$
$if(beamer)$
$else$
\usepackage{etoolbox}
\makeatletter
\providecommand{\subtitle}[1]{% add subtitle to \maketitle
  \apptocmd{\@title}{\par {\large #1 \par}}{}{}
}
\makeatother
$endif$
\subtitle{$subtitle$}
$endif$

\author{$for(authors)$$it.name.literal$$sep$ \and $endfor$}

\date{$date$}

$if(supervisor)$
\newcommand{\supervisor}{\textbf{Supervisor:} $supervisor$}
$endif$

$if(dissertation_details)$
\newcommand{\dissertationdetails}{$dissertation_details$}
$endif$

$if(beamer)$
$if(institute)$
\institute{$for(institute)$$institute$$sep$ \and $endfor$}
$endif$
$if(titlegraphic)$
\titlegraphic{\includegraphics$if(titlegraphicoptions)$[$for(titlegraphicoptions)$$titlegraphicoptions$$sep$, $endfor$]$endif${$titlegraphic$}}$endif$
$if(logo)$
\logo{\includegraphics{$logo$}}
$endif$
$endif$

\begin{titlepage}
\begin{center}

{\Huge \textbf{$title$}}\\[0.5cm]

{\Large \textit{$subtitle$}}\\[1.5cm]

\textbf{$dissertation_details$}\\[0.5cm]

\supervisor\\[2cm]

\textbf{Author:} $for(authors)$$it.name.literal$$sep$ \and $endfor$\\[0.5cm]

\vfill
{\Large \textbf{$date$}}

\end{center}
\end{titlepage}

with the _quarto.yml

project:
  type: book

book:
  title: "My thesis"
  author: "John Kowalski"
  supervisor: "Prof. Dr. Adam Smith"
  dissertation_details: "A dissertation submitted to  University X in partial fulfilment of the requirements for the degree of Doctor of Philopsophy"
  chapters:
    - index.qmd
  output-file: "book"
  search: true


format:
  pdf:
    documentclass: book
    classoption: [oneside, 12pt]
    link-citations: true
    urlcolor: blue
    toclinkcolor: blue
    number-sections: true

    toc-depth: 2
    template-partials:

[danieltomasz]

I found a good intro, so probaly I will be able to fix this myself https://www.youtube.com/watch?v=TgauMpdgPVk

Did you manage to fix it yourself?
If not, here's how it looks like and some remarks:

Remarks:

• As mentioned by cderv below, you need to to provide "supervisor" and "dissertation_details" as first level metadata:

format:
  pdf:
    documentclass: book
    classoption: [oneside, 12pt]
    link-citations: true
    urlcolor: blue
    toclinkcolor: blue
    number-sections: true
    pdf-engine: lualatex
    toc-depth: 2
    template-partials:
      - before-body.tex

supervisor: "Prof. Dr. Adam Smith"
dissertation_details: "A dissertation submitted to  University X in partial fulfilment of the requirements for the degree of Doctor of Philopsophy"

• Instead of title.tex, you need to define the title page in before-body.tex:

$if(has-frontmatter)$
\frontmatter
$endif$
$if(title)$
$if(beamer)$
\frame{\titlepage}
$else$
%\maketitle %<<< deactivate the generation of the default title page
\begin{titlepage}
  \begin{center}
    
  {\Huge \textbf{$title$}}\\[0.5cm]
    
  {\Large \textit{$subtitle$}}\\[1.5cm]
    
  $if(dissertation_details)$
  \textbf{$dissertation_details$}\\[0.5cm]
  $endif$

  $if(supervisor)$
  {\textbf{Supervisor:} $supervisor$}\\[2cm]
  $endif$
    
  \textbf{Author:} $for(authors)$$it.name.literal$$sep$ \and $endfor$\\[0.5cm]
    
  \vfill
  {\Large \textbf{$date$}}
    
  \end{center}
\end{titlepage}
$endif$
$if(abstract)$
\begin{abstract}
$abstract$
\end{abstract}
$endif$
$endif$

I dont know how to pass supervisor and dissertation_details into pandoc to use in my title.tex

Those are pandoc variables, and needs to be passed as metadata. They are pandoc level feature and needs to be passed inside a document, or as first level in _quarto.yml or below a format as they may apply only to pdf here.

Currently you are trying to set them under book and this is a Quarto level configuration not related to document template and single document renderering.

It may not be really clear and I understand. Our current doc lives at https://quarto.org/docs/journals/templates.html but we don't have exemple of passing variables.

Those examples can be found in some custom format like those in https://github.com/quarto-journals/

Hope it helps
