#25 Superfluous comma when combining xref and useeditor=false

[Anonymous]

I use the following to achieve "Editor (Hrsg.): Booktitle" when citing a collection in its own right, but at the same time "Author: Title. In: Booktitle, hrsg. von Editor" when citing a contribution to that collection:

\usepackage[style=footnote-dw,xref=true]{biblatex}
\ExecuteBibliographyOptions[incollection]{useeditor=false}

However, this produces "Author: Title, in: : Booktitle, hrsg. von Editor" with a superfluous colon. I am not sure if this should be considered a bug, or rather a mistake on my part. In any case, I would be very interested in your comments.

Best wishes,
Anton

Sorry for the delay. Could you please provide a minimal working example? Instructions on how to do that can be found here: http://biblatex.dominik-wassenhoven.de/hilfen-allgemein.shtml?de&mini (in German), http://biblatex.dominik-wassenhoven.de/hilfen-allgemein.shtml?en&mini (in English).

Thank you very much for your reply! Here is a minimal working example:

\documentclass{article}

\usepackage{filecontents}
\begin{filecontents}{\jobname.bib}
@proceedings{proceedings,
  editor    = {Some Editor},
  title     = {Some Proceedings},
  year      = {2017}
}
@inproceedings{paper1,
 author = {Some Author},
 title  = {Some Paper},
 xref   = {proceedings}
}
@inproceedings{paper2,
 author = {Some Author},
 title  = {Some Other Paper},
 xref   = {proceedings}
}
\end{filecontents}

\usepackage[backend=biber,style=footnote-dw,xref=true]{biblatex}
\addbibresource{\jobname.bib}
\ExecuteBibliographyOptions[inproceedings]{useeditor=false}

\begin{document}
Citing a conference volume\cite{proceedings} and some paper in it.\cite{paper1} And another paper by the same author.\mancite\cite{paper2}
\end{document}

When I compile it, Footnote 1 looks like this (as it should - I do want the editor in front when citing the proceedings volume itself):

Some Editor (ed.): Some Proceedings, 2017.

Footnote 2 looks like this

Some Author: Some Paper, in: : Some Proceedings, ed. by Editor (see n. 1).

As desired, the editor comes after the title when an article from the proceedings volume is cited. However, there is a superfluous colon. So footnote 2 should look like this:

Some Author: Some Paper, in: Some Proceedings, ed. by Editor (see n. 1).

Footnote 3 shows another problem that troubles me: It looks like this

Some Author: Some Other Paper, in: : Some Proceedings, ed. by Editor (see n. 1).

But as the same author has been cited in footnote 2 it should look like this (last name only; note that I have inserted \mancite to avoid "idem"):

 Author: Some Other Paper, in: Some Proceedings, ed. by Editor (see n. 1).

I am looking forward to your thoughts on this!

Thanks for the MWE. I can confirm the bug. Workaround: Replace @proceedings and @inproceedings by @collection and @incollection. I will have to look into this to make it work for @proceedings and @inproceedings as well.

Thank you for the suggested workaround! However, I get the same result when I use "collection" instead of "proceedings" -- I am not sure what I am doing wrong. Note that I have also changed "inproceedings" to "incollection" in the line

\ExecuteBibliographyOptions[incollection]{useeditor=false}

May I also ask about footnote 3 again: How can I achieve that the author is cited by his last name only (as the full name already appears in footnote 2)? Thank you so much!

I think this might have to do with the defintion of cite:xref.

I'd use in footnote-dw.cbx

\newbibmacro*{cite:xref}{%
  \ifciteseen
    {\iffieldundef{shorthand}
      {\ifnameundef{labelname}
        {}
        {\ifboolexpr{
          bool {xrefidem}
          and
          bool {bbx:edbyidem}
        }
          {\usebibmacro{cite:xref:idem}}
          {\ifbool{xref:inbook}
            {\usebibmacro{author}}
            {\usebibmacro{cite:editor}}%
             \setunit{\nametitledelim}}}%
       \usebibmacro{cite:title}}       
      {\usebibmacro{cite:shorthand}}}
    {\ifboolexpr{
      bool {xrefidem}
      and
      bool {bbx:edbyidem}
    }
       {\usebibmacro{cite:fullxrefidem}}
       {\usebibmacro{cite:fullxref}}}}

The current definition does not have the \setunit around \nametitledelim. This means that \nametitle is always printed even if nothing went before it - as happens here, because useeditor=false moves the editor after the title. I'm not sure if this causes problems in other places, but it should not.

Sorry, I saw that too late for version 1.7a, but it will be fixed in 1.7b.
