[Tex/LaTex] biblatex: How to remove the parentheses around the year in authoryear style?

biblatexpunctuation

The standard authoryear style in biblatex puts parentheses around the year in the bibliography and no parentheses around in text citation years:

Smith 2011 shows … (citation)

Smith, Joe (2011) … (bibliography)

Is there a (simple) way to turn these into:

Smith (2011) shows … (citation)

Smith, Joe. 2011. … (bibliography)

Best Answer

Thanks to egreg's great answer to biblatex: Is it possible to patch macros created with \newbibmacro?, the solution to the present question is easy: Use the new \patchbibmacro command to selectively change the definition of the date+extrayear bibmacro however this definition looks like in the first place (provided some common patterns are present).

\documentclass{article}

\usepackage[style=authoryear]{biblatex}

\makeatletter
\def\act@on@bibmacro#1#2{%
  \expandafter#1\csname abx@macro@\detokenize{#2}\endcsname
}
\def\patchbibmacro{\act@on@bibmacro\patchcmd}
\def\pretobibmacro{\act@on@bibmacro\pretocmd}
\def\apptobibmacro{\act@on@bibmacro\apptocmd}
\def\showbibmacro{\act@on@bibmacro\show}
\makeatother

\usepackage{filecontents}

\begin{filecontents}{\jobname.bib}
@misc{A01,
  author = {Author, A.},
  year = {2001},
  title = {Alpha},
}
\end{filecontents}

\addbibresource{\jobname.bib}

\nocite{*}

\begin{document}

\printbibliography

\patchbibmacro{date+extradate}{%
  \printtext[parens]%
}{%
  \setunit{\addperiod\space}%
  \printtext%
}{}{}

\printbibliography

\end{document}

EDIT: Things are even easier with egreg's xpatch package:

\documentclass{article}

\usepackage[style=authoryear]{biblatex}

\usepackage{xpatch}

\usepackage{filecontents}

\begin{filecontents}{\jobname.bib}
@misc{A01,
  author = {Author, A.},
  year = {2001},
  title = {Alpha},
}
\end{filecontents}

\addbibresource{\jobname.bib}

\nocite{*}

\begin{document}

\printbibliography

\xpatchbibmacro{date+extradate}{%
  \printtext[parens]%
}{%
  \setunit{\addperiod\space}%
  \printtext%
}{}{}

\printbibliography

\end{document}

[Tex/LaTex] How to format the extrayear field in biblatex

This is a somewhat cruel hack, but here we go. Add the following to your preamble (EDIT: Should have scanned the manual more thoroughly -- \iffieldnums seems to be the correct test, see p. 148--149):

\DeclareFieldFormat{extrayear}{%
  \iffieldnums{labelyear}{%
    \mknumalph{#1}%
  }{%
    \mkbibparens{\mknumalph{#1}}%
  }%
}

UPDATE: I have submitted a feature request at SourceForge.net: biblatex.

UPDATE: The feature request is now pending. Philipp Lehman, author of biblatex, commented:

I'll add that even though I'm not entirely convinced that this is the way to deal with work in progress. I'd rather recommend putting "in progress" in the "pubstate" field and set a label in the "label" field.

UPDATE: This feature has been implemented in biblatex v1.3 (released March 14th, 2011).

[Tex/LaTex] Biblatex authoryear in brackets and with parenthesis around the year

That's a lot of brackets and braces, but here we go. :-) I suggest to use Audrey's answer to the linked question and to add a redefinition of the cite bibmacro (namely, to add parentheses to the cite:labelyear+extrayear bibmacro).

\documentclass{article}

\usepackage[style=authoryear]{biblatex}

\makeatletter

\newrobustcmd*{\parentexttrack}[1]{%
  \begingroup
  \blx@blxinit
  \blx@setsfcodes
  \blx@bibopenparen#1\blx@bibcloseparen
  \endgroup}

\AtEveryCite{%
  \let\parentext=\parentexttrack%
  \let\bibopenparen=\bibopenbracket%
  \let\bibcloseparen=\bibclosebracket}

\renewbibmacro*{cite}{%
  \iffieldundef{shorthand}
    {\ifthenelse{\ifnameundef{labelname}\OR\iffieldundef{labelyear}}
       {\usebibmacro{cite:label}%
        \setunit{\addspace}}
       {\printnames{labelname}%
        \setunit{\nameyeardelim}}%
%     \usebibmacro{cite:labelyear+extrayear}}% DELETED
     \printtext[parens]{\usebibmacro{cite:labelyear+extrayear}}}% ADDED
    {\usebibmacro{cite:shorthand}}}

\makeatother

\usepackage{filecontents}

\begin{filecontents}{\jobname.bib}
@misc{A01,
  author = {Author, A.},
  year = {2001},
  title = {Alpha},
}
@misc{B02,
  author = {Buthor, B.},
  year = {2002},
  title = {Bravo},
}
\end{filecontents}
