I need to add a period after the (last) author in my bibliography, right before the printed year. From Period after last author name in biblatex when terseinits = true I learned that I can do this with

\usepackage{xpatch}
\xpretobibmacro{date+extrayear}{\setunit{\addperiod\space}}{}{}

But when the biblatex option dashed is set to true, and there are multiple entries within one year so that the letters a and b are added to separate them, the period is added after the year inside the parentheses instead of going after the dash.

\documentclass{article}
\usepackage[style = authoryear-comp, dashed = true]{biblatex}
\usepackage{xpatch}
\xpretobibmacro{date+extrayear}{\setunit{\addperiod\space}}{}{}
\usepackage{filecontents}
\begin{filecontents}{\jobname.bib}
@article{lennon1963,
    AUTHOR = "John Lennon",
    TITLE = "Does she love you? Yeah, yeah, yeah",
    JOURNALTITLE = "Top of the Pops",
    YEAR = "1963",
    PAGES = "5--13"}
@article{lennon1967a,
    AUTHOR = "John Lennon",
    TITLE = "A day in whose life?",
    JOURNALTITLE = "Top of the Pops",
    YEAR = "1967",
    PAGES = "12--24"}
@article{lennon1967b,
    AUTHOR = "John Lennon",
    TITLE = "Is love all you need?",
    JOURNALTITLE = "Top of the Pops",
    YEAR = "1967",
    PAGES = "25--34"}
\end{filecontents}
\addbibresource{\jobname.bib}
\begin{document}
\nocite{*}
\printbibliography
\end{document}

You could check if the dash is printed, if so we do not add the period, otherwise we print it.

\xpretobibmacro{date+extrayear}
  {\usebibmacro{bbx:dashcheck}
    {}
    {\setunit{\addperiod\space}}}
  {}{}

However, I think in this case a long solution is the most robust one. (You see how fickle the patching makes the macros.)

We replace some \setunit{\addspace} by \setunit{\addperiod\space} in the author, bbx:editor and bbx:translator macros:

\makeatletter
\renewbibmacro*{author}{%
  \ifboolexpr{
    test \ifuseauthor
    and
    not test {\ifnameundef{author}}
  }
    {\usebibmacro{bbx:dashcheck}
       {\bibnamedash}
       {\usebibmacro{bbx:savehash}%
        \printnames{author}%
        \iffieldundef{authortype}
          {\setunit{\addperiod\space}}
          {\setunit{\addcomma\space}}}%
     \iffieldundef{authortype}
       {}
       {\usebibmacro{authorstrg}%
        \setunit{\addperiod\addspace}}}%
    {\global\undef\bbx@lasthash
     \usebibmacro{labeltitle}%
     \setunit*{\adddperiod\space}}%
  \usebibmacro{date+extrayear}}


\newbibmacro*{bbx:editor}[1]{%
  \ifboolexpr{
    test \ifuseeditor
    and
    not test {\ifnameundef{editor}}
  }
    {\usebibmacro{bbx:dashcheck}
       {\bibnamedash}
       {\printnames{editor}%
        \setunit{\addcomma\space}%
        \usebibmacro{bbx:savehash}}%
     \usebibmacro{#1}%
     \clearname{editor}%
     \setunit{\addperiod\space}}%
    {\global\undef\bbx@lasthash
     \usebibmacro{labeltitle}%
     \setunit*{\addperiod\space}}%
  \usebibmacro{date+extrayear}}


\newbibmacro*{bbx:translator}[1]{%
  \ifboolexpr{
    test \ifusetranslator
    and
    not test {\ifnameundef{translator}}
  }
    {\usebibmacro{bbx:dashcheck}
       {\bibnamedash}
       {\printnames{translator}%
        \setunit{\addcomma\space}%
        \usebibmacro{bbx:savehash}}%
     \usebibmacro{translator+othersstrg}%
     \clearname{translator}%
     \setunit{\addperiod\space}}%
    {\global\undef\bbx@lasthash
     \usebibmacro{labeltitle}%
     \setunit*{\addspace}}%
  \usebibmacro{date+extrayear}}
\makeatother

To include a period after the dash, go with

\renewcommand*{\bibnamedash}{%
  \ifdimless{\leftmargin}{0.75em}
    {\mbox{\textemdash\addperiod\space}}
    {\makebox[\leftmargin][l]{%
       \ifdimless{\leftmargin}{1.25em}
         {\textendash\addperiod}
         {\textemdash\addperiod}}}}

This just adds \addperiod after the different dashes.

  • How easy would it be to implement an added period after the dash, i.e. -. (1967a).? It's not crucial, I guess, but the journal style sheet does indicate it ... :-/ – Sverre Apr 27 '14 at 14:46
  • @Sverre I guess, one could just modify the \bibnamedash command to include the period. See edit. – moewe Apr 27 '14 at 14:52
  • That works, except that there is no space after the period, so it prints -.(1967a) rather than -. (1967a). I tried just adding \addspace and \space after \addperiod in your code, but nothing happened ... – Sverre Apr 27 '14 at 15:01

    @Sverre I do think there is a space between the period and the parentheses, my pdf reader even lets me select one. If you insist on more space, add a \space just before the last curly brace in the redefinition above. – moewe Apr 27 '14 at 15:05
  • You're right. It does add a space in this MWE, but it doesn't when I added your code to my style sheet .sty file. I'll try to find the culprit line in my .sty file that causes this. – Sverre Apr 27 '14 at 15:09
