General ⇒ BibLaTeX Combination of bibstyle=authoryear and citestyle=al

[dianamehl]

Hey,

I am currently writing my thesis and I have a problem with my bibliography:

I am using the bibstyle authoryear and the citestyle alphabetic in BibLaTex.
How can I show the citation-code in my bibliography?

Thanks

Welcome, the question is just as unclear as in german.

User Henri gave the answer on TeXwelt.de

To get an authoryear bibliography including the labels of the
alphabetic style you need to take a closer look at the internals.
In short, the bibliography is a list, whose appearance can be
controlled, for example the label.

biblatex defines a few commands, for example
\DeclareFieldFormat to control the formatting of a
field; or \defbibenvironment to control the
appearance of the list.

biblatex loads file authoryear.bbx to achieve an author-year
bibliography. To get the label from alphabetic, the relevant code
is used from alphabetic.bbx. To get the missing bracket, you can
use
\DeclareFieldFormat{labelalphawidth}{\mkbibbrackets{#1}}.

Code: Select all

\documentclass{article}
\usepackage[citestyle=alphabetic,bibstyle=authoryear]{biblatex}
\addbibresource{biblatex-examples.bib}

% begin: excerpt from `alphabetic.bbx'
\DeclareFieldFormat{labelalphawidth}{\mkbibbrackets{#1}}

\defbibenvironment{bibliography}
  {\list
     {\printtext[labelalphawidth]{%
        \printfield{prefixnumber}%
    \printfield{labelalpha}%
        \printfield{extraalpha}}}
     {\setlength{\labelwidth}{\labelalphawidth}%
      \setlength{\leftmargin}{\labelwidth}%
      \setlength{\labelsep}{\biblabelsep}%
      \addtolength{\leftmargin}{\labelsep}%
      \setlength{\itemsep}{\bibitemsep}%
      \setlength{\parsep}{\bibparsep}}%
      \renewcommand*{\makelabel}[1]{##1\hss}}
  {\endlist}
  {\item}
