Change citation style from square brackets to forward slashes

Question

In latex, how can I change citation style from square brackets (e.g. "As authors in [1] show ...") to forward slashes ("As authors in /1/ show ...")?

EDIT To answer the comments below... I don't know the name of citation style. It is just a requirement of MSc thesis formatting.

Main document (dissertation.tex) looks like that

\documentclass[a4paper,14pt]{extreport}
\input{packages}        
\input{styles}          
\input{data}            
\begin{document}
\input{introduction}   
\input{part1}          
\input{references}     
\end{document}

The command used to generate pdf

latexmk -pdf -pdflatex="xelatex %O %S" dissertation

EDIT 2 Bibliography style, the style is defined here (https://github.com/AndreyAkinshin/Russian-Phd-LaTeX-Dissertation-Template/blob/master/Synopsis/utf8gost71u.bst)

\bibliographystyle{utf8gost71u} 
\makeatletter
\renewcommand{\@biblabel}[1]{#1.}
\makeatother

Answer 1

You can do this using the cite package:

\usepackage{cite}
\def\citeleft{/}
\def\citeright{/}

I think it's quite self-explanatory:)

Answer 2

For completeness, here's a solution that's based on the natbib citation management package:

\usepackage{natbib}
\bibpunct{/}{/}{;}{n}{}{,}

The result of a full MWE:

\documentclass{article}
\usepackage{filecontents}
\begin{filecontents}{myxyz.bib}
@article{xyz,
  author = "Anne Author",
  title  = "Thoughts",
  journal= "Circularity Today",
  volume = 1,
  number = 2,
  pages  = "3-4",
  year   = 5001,
}
\end{filecontents}

\bibliographystyle{plainnat} % no access to "utf8gost71u.bst"
\makeatletter
\renewcommand{\@biblabel}[1]{#1.}
\makeatother

\usepackage{natbib}
\bibpunct{/}{/}{;}{n}{}{,}

\begin{document}
\noindent
\cite{xyz}

\bibliography{myxyz}
\end{document}
