Text Formatting ⇒ Change behavior of cite command in text

[alex170872]

Hi,

I would like to change the behavior of the \cite command in the text. I do not change at all how the references from e.g. bibtex are listed in the bibliography, I want to change the appearence of \cite in the text.

An example: I put a \cite{ref1} into my text, which will become later e.g.

text blah [1] blah text

now I want to redefine/newdefine/change cite (i.e. create a new command citeb) that gives the same output in the text, but e.g. the content in the brackets bold, like

text blah [1] blah text

I have tried to do that with \textbf\cite{ref1}}, which does not work. Is there a way to define such a modified cite command, that prints out the cite key in bold, italics etc??


Thanks
Alex

Requires the redefinition of a helper macro from the LaTeX kernel.

Code: Select all

\documentclass[11pt,a4paper]{article}
\usepackage[T1]{fontenc}
\usepackage[utf8]{inputenc}

\makeatletter
\def\@citex[#1]#2{\leavevmode
  \let\@citea\@empty
  \@cite{\bfseries\@for\@citeb:=#2\do
    {\@citea\def\@citea{,\penalty\@m\ }%
     \edef\@citeb{\expandafter\@firstofone\@citeb\@empty}%
     \if@filesw\immediate\write\@auxout{\string\citation{\@citeb}}\fi
     \@ifundefined{b@\@citeb}{\hbox{\reset@font\bfseries ?}%
       \G@refundefinedtrue
       \@latex@warning
         {Citation `\@citeb' on page \thepage \space undefined}}%
       {\@cite@ofmt{\csname b@\@citeb\endcsname}}}}{#1}}
\makeatother
   
\begin{document}
  \cite{key}

  \begin{thebibliography}{9}
  \bibitem{key} Bibliography Item
  \end{thebibliography}
\end{document}

Unwanted side effects cannot be ruled out.

Probably. But since this would mean a lot of work and I'm short in time I can't offer this solution at the moment.

Hi,

thanks for the help, but the definition of citex given in the example does not seem to work at all. When compiling latex it tells me

Undefined control sequence.

It looks like latex does not find a definition for citeb (even if I rename \def\@citex[#1]#2{\leavevmode to \def\@citeb[#1]#2{\leavevmode) and independent of whether I include those fontenc and inputenc packages.

Is this example supposed to work, or just an example of how to do things? I myself have absolutely no idea how to work with any of these '@' variables or how to change some internal 'things'.

So if someone has a working example of how to create a citeb command to cite something in bold, while leaving the cite command to work as normal*!) that would be great.


Thanks

The example has been tested and works as provided. Did you try to compile it as is?

[alex170872]

Oh I see, this formalism changes cite, but does not introduce a new command.
Maybe I have not bee very clear in my first post, but what I would like to have is a command 'citeb' to cite something in bold, while having the normal 'cite' command as usual to cite other refs just as before.

Is that possible to implement like this?


Thanks
Alex
