Biblatex \autocite need adaption for nested footnotes for year-author in b=tufte-book

Question

I need in a tufte-book citations with author-year and used the recommendations for the author-year style. Unlike the case there, I want

the simple citation in regular text as sidenote (as is automatically produced with autocite=footnote and the tufte style) and
a plain citation in footnotes.

I have tried to change the code given there to have autocite a footnote in regular text and a plain citation in a footnote, but have not succeeded.

What must be changed?

% \documentclass[a4paper,openany,nobib]{tufte-book}  
\documentclass{article}
\usepackage[style=authoryear,
            autocite=footnote]{biblatex}

\DeclareAutoCiteCommand{inlineplainfootnote}{\mysmartcite}{\mysmartcites}

\DeclareCiteCommand{\mysmartcite}[\iffootnote\textnormal\mkbibparens]
  {\usebibmacro{prenote}}
  {\usebibmacro{citeindex}%
   \usebibmacro{cite}}
  {\multicitedelim}
  {\usebibmacro{postnote}}

\DeclareMultiCiteCommand{\mysmartcites}
    [\iffootnote\textnormal\mkbibparens]{\mysmartcite}{\multicitedelim}

\ExecuteBibliographyOptions{autocite=inlineplainfootnote}

% \usepackage{filecontents}

\begin{filecontents}{\jobname.bib}
@misc{A01,
  author = {Author, A.},
  year = {2001},
  title = {Alpha},
}
@misc{B02,
  author = {Poet, B.},
  year = {2002},
  title = {Beta},
}
\end{filecontents}


\addbibresource{\jobname.bib}
\begin{document}
\null\vfill% just for the example
Some text with a reference \autocite{A01} which should become a sidenote i.e. 1 and the sidenote should say: (Author 2001) .
Some more text with a citation which should become a footnote or sidenote saying: Author 2001, Poet 2002 \autocite{A01, B02}.
Some text with a footnote \footnote{A footnote with \autocite{B02}.} which should say: 1 A footnote with (Poet 2002).
And some text with a footnote with two citations \footnote{Two citations\autocite{B02, A01}} which should say: 2 Two citations(Poet 2002; Author 2001).
\printbibliography
\end{document}

Aside: I have added a second bib entry, but it cannot be found. what is wrong there?

What do you mean by "plain citation"? Can you show us what the output should look like in the example? — moewe, Jul 14 '23 at 15:39
As to your aside: filecontents does not overwrite an existing file. So if you started out with a .bib file of the same basename as your .tex file or edited the filecontents later to include the second reference, the old file with the old contents will stick around. I get two working citations in your example. Delete the test .bib file (and the .aux, .bbl and .bcf) and try again. — moewe, Jul 14 '23 at 15:40
@moewe - I have put the expected output in the example file. thank you for asking! - I recently switched to vscode with latex-workshop and did not see that clean up did not delete the .bib file - I expected the error in missing , or similar. — user855443, Jul 14 '23 at 18:53
@user855443 Note you should be very glad VSC doesn't delete your bibliography database! — cfr, Jul 15 '23 at 01:46
@cfr - I have my true bib files stored somewhere else, but I can see your point. It is just another piece of information somebody not using latex every day may not have present. — user855443, Jul 15 '23 at 08:32

I think you don't need to define any new citation commands: You could be pretty happy with the standard \smartcite approach were it not for the fact that biblatex can't detect footnotes in tufte-book. So all we need to do is make it detect footnotes. This is done by inserting \toggletrue{blx@footnote} in the right place in the footnote implementation.

\documentclass[a4paper,openany,nobib]{tufte-book}
\usepackage[style=authoryear, autocite=footnote]{biblatex}
\makeatletter
\renewcommand@footnotetext[2][0pt]{%
  \marginpar{%
    \hbox{}\vspace{#1}%
    \def\baselinestretch {\setspace@singlespace}%
    \reset@font\footnotesize%
    @tufte@margin@par% use parindent and parskip settings for marginal text
    \vspace{-1\baselineskip}\noindent%
    \protected@edef@currentlabel{%
       \csname p@footnote\endcsname@thefnmark%
    }%
    \color@begingroup%
       @makefntext{%
         \toggletrue{blx@footnote}%
         \ignorespaces #2%
       }%
    \color@endgroup%
  }%
}%
\makeatother
\addbibresource{biblatex-examples.bib}
\begin{document}
Some text with a reference \autocite{sigfridsson}
Some more text with a citation\autocite{sigfridsson, nussbaum}.
Some text with a footnote \footnote{A footnote with \autocite{nussbaum}.}
And some text with a footnote with two citations \footnote{Two citations\autocite{nussbaum, sigfridsson}}
\printbibliography
\end{document}

Note that this does not include parentheses in footnotes that contain only citations.

Excellent - worked immediately and solved a vexing problem with footnotes in footnotes for the tufte style (the mechanism should probably be incorporated somewhere in the style?). I am impressed with the simplicity of the solution! Thanks a lot! — user855443, Jul 15 '23 at 08:47
