[Tex/LaTex] Using \cite with biber inside tikzpictures

biberbiblatexcitingtikz-pgf

I'm using biber and want to cite references inside a tikzpicture. I followed this answer that described how to do it with bibtex and it works nicely, but when switching to use biber, it doesn't work anymore:

\documentclass{article}
\usepackage{tikz}

\usepackage[backend=biber]{biblatex}

\begin{document}

\begin{tikzpicture}[show/.style={circle,draw}]
\node[show]    (newpaper)    at    (0,2)    
    [label=right:{This 2011 paper ...}]    
    {\cite{newpaper}};
\node[show]    (oldpaper)   at     (0,0)    
     [label=right:{This paper came out in 1900 ...}]    
    {\cite{oldpaper}};
\draw[->]    (oldpaper) -- (newpaper);
\end{tikzpicture}


%\bibliographystyle{amsplain}
\begin{thebibliography}{10}
\bibitem{newerpaper}B. Becker, \emph{Even Newer Stuff}, 2012.
\bibitem{newpaper}C. Charles, \emph{New Stuff}, 2011.
\bibitem{oldpaper}H. Huckley, \emph{Old Stuff}, 1900.
\end{thebibliography}
\end{document}

Does anyone know of a solution without me having to switch to use bibtex?

UPDATE:

As noted by several below, my original code I posted was an easy fix. The actual bug I found was a result of my larger LaTeX code and I found the issue. Here's the updated code that has the issue:

\documentclass{article}
\usepackage{tikz}

\usetikzlibrary{external}
\tikzexternalize[prefix=fig/]

\usepackage[backend=biber]{biblatex}

\usepackage{filecontents}

\begin{filecontents}{\jobname.bib}
@book{newerpaper,
    author={B. Becker},
    title={Even Newer Stuff},
    date={2012}
}

@book{newpaper,
    author={C. Charles},
    title={New Stuff},
    date={2011}
}

@book{oldpaper,
    author={H. Huckley},
    title={Old Stuff},
    date={1900}
}

\end{filecontents}

\addbibresource{\jobname.bib}

\begin{document}

%\tikzexternaldisable
\begin{tikzpicture}[show/.style={circle,draw}]
\node[show]    (newpaper)    at    (0,2)    
[label=right:{This 2011 paper ...}]    
{\cite{newpaper}};
\node[show]    (oldpaper)   at     (0,0)    
[label=right:{This paper came out in 1900 ...}]    
{\cite{oldpaper}};
\draw[->]    (oldpaper) -- (newpaper);
\end{tikzpicture}
%\tikzexternalenable

\printbibliography

\end{document}

The problem is with the \tikzexternalize[prefix=fig/] command. I got around this issue by adding \tikzexternaldisable before the tikzpicture and \tikzexternalenable after the tikzpicture.

As suggested in the comments, you should move to biblatex's way of dealing with the bibliography, rather than doing it by hand. E.g.:

\documentclass{article}
\usepackage{tikz}

\usepackage[backend=biber]{biblatex}

\usepackage{filecontents}

\begin{filecontents}{\jobname.bib}
@book{newerpaper,
    author={B. Becker},
    title={Even Newer Stuff},
    date={2012}
}

@book{newpaper,
    author={C. Charles},
    title={New Stuff},
    date={2011}
}

@book{oldpaper,
    author={H. Huckley},
    title={Old Stuff},
    date={1900}
}

\end{filecontents}

\addbibresource{\jobname.bib}

\begin{document}

\begin{tikzpicture}[show/.style={circle,draw}]
\node[show]    (newpaper)    at    (0,2)    
    [label=right:{This 2011 paper ...}]    
    {\cite{newpaper}};
\node[show]    (oldpaper)   at     (0,0)    
     [label=right:{This paper came out in 1900 ...}]    
    {\cite{oldpaper}};
\draw[->]    (oldpaper) -- (newpaper);
\end{tikzpicture}

\printbibliography

\end{document}

Which produces:

Edit: As it turned out, the issue is essentially one of the correct use of biblatex/biber, and has little to do with TikZ, so a list of starters with biblatex could be handy:

[Tex/LaTex] Rotate a node but not its content: the case of the ellipse decoration

The source of the difficulty is that ellipses are constructed in a particular way in TikZ. They are paths that start from the x-axis and proceed counter-clockwise around their centre. The vast majority of the time, the exact parametrisation doesn't matter. You appear to have found the one situation where it does!

In the actual question, you only want to be able to mirror the ellipse, and so draw it starting from the negative x-axis (the title of the question suggests a more flexible approach). That's actually not too hard since we can exploit the symmetry of the ellipse. The key is to provide it with a negative x-radius, since then it will start from the negative x-axis (and proceed clockwise, but we could correct for that by negating the y-radius as well). To do this, we interrupt the call from the node shape to the drawing command and flip the sign of the x-radius. The simplest way to do this is to redefine the \pgfpathellipse macro to do the negation and then call the original macro. The following code does this.

\documentclass{article}
\usepackage{tikz}
\usetikzlibrary{decorations,shapes,decorations.markings}
\makeatletter
\let\origpgfpathellipse=\pgfpathellipse
\def\revpgfpathellipse#1#2#3{%
  #2%
  \pgf@xa=-\pgf@x
  \origpgfpathellipse{#1}{\pgfqpoint{\pgf@xa}{0pt}}{#3}}
\makeatother

\tikzset{
  reversed ellipse/.style={
    ellipse,
    reverse the ellipse%
  },
  reverse the ellipse/.code={
    \let\pgfpathellipse=\revpgfpathellipse
  }
}
\begin{document}
\begin{tikzpicture}
\node[ellipse,
  draw,
  postaction={
    decorate,
    decoration={
      markings,
      mark=at position 1 with {
        \arrow[line width=5pt,blue]{>}
      }
    }
  }
] at (0,0) {hello world};

\node[reversed ellipse,
  draw,
  postaction={
    decorate,
    decoration={
      markings,
      mark=at position 1 with {
        \arrow[line width=5pt,blue]{>}
      }
    }
  }
] at (0,-2) {hello world};
\end{tikzpicture}

\end{document}

Here's the result:

rotated ellipse

(the arrow got clipped, but you can see where it lies)

[Tex/LaTex] Citing (author, journalabbr., year) needed

First thing to do is to add a field for the journal abbreviation to the article entrytype, journalabbr in the MWE. Therefore you need to declare a datamodel (an extra file; in the MWE I've used filecontents to simulate that) and you have to tell biblatex/biber to use it in the package options.

Then you have to modify the cite command, so it fits your needs. \citep from the authoryear-style (your citestyle) uses the \cite command. There you just have to add a switch, which checks if the field journalabbr is empty or not, and prints it out or not.

Last but not least you have to add the abbreviation fields to the entries.

MWE:

\begin{filecontents}{min.bib}
@article{boisson2003unexpected,
  title={Unexpected protein families including cell defense components feature in the N-myristoylome of a higher eukaryote},
  author={Boisson, B. and Giglione, Carmela and Meinnel, Thierry},
  journal={Journal of Biological Chemistry},
  journalabbr={JBC},
  year={2003},
  publisher={ASBMB}
}
\end{filecontents}

\begin{filecontents}{authorjabbryear.dbx}
\ProvidesFile{authorjabbryear.dbx}
\DeclareDatamodelFields[type=field,datatype=literal]{journalabbr}
\DeclareDatamodelEntryfields[article]{journalabbr}
