Biblatex: using “dashed” in one refsection but not another

Question

Am I right that it is impossible to turn the dashed option on for one refsection, but not for another within the same document?

(If you're wondering why one would need that: I'm compiling a research proposal which has a complicated structure (stipulated by the funding organization). My CV is part of that structure and hence my list of publications. Using dashes in your CV looks silly. But I'd like to use them in the other sections, where I'm citing other people's works. (The CV-part is a seperate refsection in order to prevent the a,b,c suffixes))

Answer 1

Changing the dashed option

We can achieve this by calling \AtNextBibliography{\renewbibmacro*{bbx:savehash}{}}, which redefines bbx:savehash bibmacro (the one that tells the style to save and use dashes) at the beginning of the next \printbibliography (it can be used out of the preamble).

\AtNextBibliography{\renewbibmacro*{bbx:savehash}{}}

Removing the alphabetical label in the date

It's the same principle of changing the dashed option: we must set the blx@labeldate toggle to false within a given bibliography; once again, we use \AtNextBibliography to set it, and we will use it within a refsection.

\AtNextBibliography{\settoggle{blx@labeldate}{false}}

Here's a MWE:

^{(\DeclareSourcemap is used here to easily produce a list of a single author's publications. For more details, refer to How to print a bibliography for a particular author only?)}

\documentclass{article}
\usepackage[style=authoryear]{biblatex}
\addbibresource{biblatex-examples.bib}
\DeclareSourcemap{
  \maps[datatype=bibtex]{
    \map{
      \step[fieldsource=author,
            match=Kant,
            final]
      \step[fieldset=keywords, fieldvalue=own]
    }
  }
}
\begin{document}
\autocites{knuth:ct,knuth:ct:a,companion,kant:kpv,kant:ku}

\begin{refsection}
\AtNextBibliography{
  \renewbibmacro*{bbx:savehash}{}
  \settoggle{blx@labeldate}{false}
}
\nocite{*}
\printbibliography[keyword=own,title={These are my Works}]
\end{refsection}
\printbibliography[title={These are awesome works by other people I like}]
\end{document}
