Biblatex authoryear in brackets and with parenthesis around the year

Question

I use square brackets around my citations (/parencite) from the answer to Biblatex, author-year, square brackets. So now I have

[Doe 1995]

in text. But I would like to have

[Doe (1995)]

in text. The way the bibliography is should not change. It now is like this:

Doe, J. (1995), ...

How do I achieve this?

Answer 1

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}

\addbibresource{\jobname.bib}
