Update .sty files for latest Pandoc citeproc approach

[seananderson]

The latest Pandoc has changed how references are handled by the default 'citeproc' method. Argh!

You can verify this is an issue by trying to build the unit tests. I tried with the tech report.

See https://tex.stackexchange.com/questions/695228/undefined-control-sequence-using-citeproc-to-convert-md-to-pdf-with-a-template
And an example of extra code now needed in the preamble here: jgm/pandoc#9031 (comment)

However, it's more complicated than this for us and I'm out of time to try fixing this right now. So, I'm documenting where I left off. Working on the tech report, here is what I've found:

• I added the above code

\NewDocumentCommand\citeproctext{}{}
\NewDocumentCommand\citeproc{mm}{%
  \begingroup\def\citeproctext{#2}\cite{#1}\endgroup}
\makeatletter
% avoid brackets around text for \cite:
 \def\@biblabel#1{}
 \def\@cite#1#2{{#1\if@tempswa , #2\fi}}
\makeatother
\newlength{\cslhangindent}
\setlength{\cslhangindent}{1.5em}
\newlength{\csllabelwidth}
\setlength{\csllabelwidth}{3em}
\newlength{\cslentryspacing}
\setlength{\cslentryspacing}{0em}
\usepackage{enumitem}
\newlist{biblist}{itemize}{1}
\setlist[biblist]{label={},leftmargin=\cslhangindent,itemindent=-1\cslhangindent,itemsep=\cslentryspacing}
\usepackage{calc}
\newcommand{\CSLBlock}[1]{#1\hfill\break}
\newcommand{\CSLLeftMargin}[1]{\parbox[t]{\csllabelwidth}{#1}}
\newcommand{\CSLRightInline}[1]{\parbox[t]{\linewidth - \csllabelwidth}{#1}\break}
\newcommand{\CSLIndent}[1]{\hspace{\cslhangindent}#1}

• Need to remove % \RequirePackage[authoryear]{natbib} % Citations
• Need to remove % \bibpunct{(}{)}{;}{a}{}{,} % Punctuation for citations
• Need to remove (or maybe better, edit)

\newenvironment{CSLReferences}[3] % #1 hanging-ident, #2 entry spacing
 {% don't indent paragraphs
  \setlength{\parindent}{0pt}
  % turn on hanging indent if param 1 is 1
  \ifodd #1 \everypar{\setlength{\hangindent}{\cslhangindent}}\ignorespaces\fi
  % set entry spacing
  \ifnum #2 > 0
  \setlength{\parskip}{#2\baselineskip}
  \fi
 }%
 {}

• If removing that, need to stop adding (or remove?) from the .tex:

%Defines cslreferences environment
%Required by pandoc 2.8
% %Copied from https://github.com/rstudio/rmarkdown/issues/1649
% \newlength{\cslhangindent}
% \setlength{\cslhangindent}{1.5em}
% \newenvironment{cslreferences}%
%   {}%
%   {\par}

Then in reference list, need to stop injecting CSLReferences at beginning and end of bibliography. I forget if we're doing that or pandoc was. Replace with biblist?

e.g. \begin{CSLReferences} becomes \begin{biblist}

Hit the Blame button on this file: https://github.com/jgm/pandoc-templates/blame/master/default.latex
and start at line 338 % definitions for citeproc citations. That's what needs to change (keeping in mind we need formatting to match CSAS requirements).

This is all done (except resdoc-b). Note, however, that for some document types I had to change the default rendering back to bookdown::render_book() for the French version to build. You can see which ones in the 2 commits linked above in this issue with their TODO. I couldn't quickly figure out what was going wrong with the csasdown::render() versions.

On the server we have Pandoc version:

pandoc 2.9.2.1
Compiled with pandoc-types 1.20, texmath 0.12.0.2, skylighting 0.8.5

With this, the English techreport fails for me as it is now using either csasdown::render() or bookdown::render_book(). I can fix it (maybe the indents etc are wrong though) by changing the code starting here

csasdown/inst/csas-style/tech-report.sty

Line 436 in 92f7f64

\usepackage{enumitem}

to this:

\usepackage{enumitem}
\newenvironment{CSLReferences}%
  {}%
  {\par}
% \newlist{CSLReferences}{itemize}{1}
% \setlist[CSLReferences]{label={},
%   leftmargin=\cslhangindent,
%   itemindent=-1\cslhangindent,
%   parsep=\parskip,
%   itemsep=\cslentryspacing}
\usepackage{calc}

Appears it cannot be a list the way it is now...

This should now be working with pandoc < 3.1.7 and with pandoc >= 3.1.8. Pandoc 3.1.7 requires its own template, so csasdown checks for it and stops. I check the pandoc version on the fly and uncomment/comment sections of the .sty file as needed. 417f88c
