How to correctly set latex-babel for pdf output

[produnis]

Hi there,
I am creating a thesis-template using quarto-book. While everything else is working as intended, I am struggeling to set up latex-babel for german language support for PDF output. I want "List of Figures" and "List of Tables" to be in german language, and I need support for the german ß Symbol.

A "working" -not working- example can be found here: https://git.zilium.de/produnis/quarto-thesis-hsnr

git clone [email protected]:produnis/quarto-thesis-hsnr.git

In _quarto.yml I specified

book:
  lang: de-DE

format:
  pdf:
    documentclass: scrbook
    classoption:
      - ngerman
    include-in-header: "latex-header.tex" 

See full yml here: https://git.zilium.de/produnis/quarto-thesis-hsnr/-/blob/main/_quarto.yml

In latex-header.tex I added

\usepackage[ngerman]{babel}

and I even tried to force it the hard way with

\renewcommand{\listfigurename}{Abbildungsverzeichnis}
\renewcommand{\listtablename}{Tabellenverzeichnis}
\renewcaptionname{ngerman}{\listfigurename}{Abbildungsverzeichnis}
\renewcaptionname{ngerman}{\listtablename}{Tabellenverzeichnis}

but in my PDF output file, there is still "List of Figures" and "List of Tables" instead of "Abbildungsverzeichnis"

And the ß-Symbol is rendered as SS.

These steps all work with my other pure-latex-only-projects, so I am out of ideas how to make it work with quarto.

Does anyone have a working example on how to switch latex output to [ngerman]{babel} ?

I solved the "ß"-problem by removing \usepackage[T1]{fontenc}.....

...but still no clue how to change "List of FIgures" and "List of Tables"....

This is the tex-output. As you can see at the last lines of this code, my commands are overwritten by quarto...

ok thanks. The command inserted by Quarto should use the translation file if you correctly set the lang option, as explained in https://quarto.org/docs/authoring/language.html#lang-option
so lang: de should load the _language-de.yaml that has the translation

quarto-cli/src/resources/language/_language-de.yml

Lines 66 to 68 in 5bfc2ec

	crossref-lof-title: "Abbildungsverzeichnis"
	crossref-lot-title: "Tabellenverzeichnis"
	crossref-lol-title: "Listingverzeichnis"

I see now that you put it under book - Do you use VSCODE or RSTUDIO IDE ? Validation should help you know if this is valid. I believe it is not an option under book, but should be under the format.

• See PDF reference: https://quarto.org/docs/reference/formats/pdf.html#language
• Book reference has not lang (https://quarto.org/docs/reference/projects/books.html)

I think where you put it, it did not get picked up, even by Pandoc - hence the need to add yourself \usepackage[ngerman]{babel} I believe.

You can also provide custom translation in the YAML, so you could change the Quarto default without all the translation
https://quarto.org/docs/authoring/language.html#alternate-language

thank you so much!!!!!!!!!!!!
removing lang: de-DE from book and adding lang: de to format-pdf solved my problem!

format:
  pdf:
    lang: de

with this, there is no need for my crossref language specifications either, everything is working as intended.

THANK YOU!!!!

Awesome ! Let's mark this as answer. Sorry to not have seen the yaml misplacement right away.

Hello - sounds like this is related to #3059 (comment) (missing locale)?
