Indirect citation support

[jrmoserbaltimore]

Either I can't find it in the docs or there's no support for indirect citations. This is relatively straightforward so hopefully that's enough information to understand the issue.

Please add this, or add it to the docs, or point me at whatever I failed to properly read. I'm interested in any limitations (does biblatex even have a citation command for indirect citations? I don't see one).

Hmm ... I don't think there is a generic way to do this currently and it would have to be looked at as part of the style unless @moewew knows of a way to do this in a generic way?

However, you can get this format manually:

\documentclass{article}
\usepackage[style=apa]{biblatex}
\addbibresource{biblatex-examples.bib}
\begin{document}
\nocite{springer}
This follows from \textcite[][as cited in Springer, 1950]{bertram}.
\printbibliography
\end{document}

We just don't allow nested citations currently so no citation commands in postnotes.

This also depends heavily on how you want to treat the secondary and primary source in terms of the bibliography.

The main problem is what @plk already mentioned: you can't nest citation commands, so something like

This follows from \textcite[][as cited in \nptextcite{sigfridsson}]{bertram}.

won't work.

For specific use cases you can cook up specific solutions, e.g. https://tex.stackexchange.com/q/27964/35864, but I'm not sure if within the current framework there is something that would be universal and flexible enough.
