Separate bibliographies per chapter in Quarto (PDF output)

I like to have multiple bibliographies in a Quarto document (PDF output). Could you give me a hint what is wrong with this code? (I've tried the refsection evironment from biblatex Separate bibliographies per chapter? )

---
title: "resize image"
bibliography: refs.bib 
format: pdf
header-includes:
  \usepackage{biblatex}
---

\begin{refsection}
Text \cite{ref1}
\printbibliography
\end{refsection}

Produces strange output like: Text [ref1]

Solution

  • Update (using pandoc filter)

    Using the pandoc filter section-bibliographies as a Quarto Extension, provided by @tarleb, section-wise bibliographies can be created more neatly.

    ---
title: "Sectionwise Bibliography"
bibliography: pkg.bib 
format: pdf
keep-tex: true
filters:
  - section-bibliographies
reference-section-title: References

# Quarto

Quarto enables you to weave together content and executable code into a finished document. To learn more about Quarto see <https://quarto.org>.

[see @R-knitr]

# Running Code

When you click the **Render** button a document will be generated that includes both content and the output of embedded code. 

[see @R-ggplot2]

    using pandoc filter section-bibliographies

    Using Latex

    Quarto itself has an option cite-method to specify to use the biblatex as the citation manager.

\begin{refsection}
Text \cite{R-knitr}
\printbibliography
\end{refsection}
