Making uses of cleveref packages standalone

Question

I have used cleveref package for referring to equations, figures, etc in an article. However, I wish to compile my tex file on another system which only has a basic version of tex. I wish to make my tex file sort of stand-alone .

Is there any way I can use a code which will look at my use of formatting references and replace all \cref commands with \ref commands but in the appropriate format.

Ex. when I use:

\crefformat{figure}{Fig.~(#2{}#1{}#3)}
\crefformat{section}{Sec.~(#2{}#1{}#3)}
\crefformat{equation}{Eq.~(#2{}#1{}#3)}

It should replace the instances of:

\cref{fig:label-for-fig}
\cref{eq:label-for-eq}
\cref{sec:label-for-sec}

by:

Fig. \ref{fig:label-for-fig}
Eq. \ref{eq:label-for-eq}
Sec. \ref{sec:label-for-sec}

(respectively).

Can anyone suggests a code that already exists ? Any language is ok if I can manage to run it on my system.

Answer 1

Trying to reproduce the behavior of cleveref without having it is just a waste of time and hopeless: it's a large package and does things in a, well, clever way.

I don't think you'll use the system with the basic TeX distribution for producing the final version of your document, so delving with those prefixes has dubious usefulness.

Just add to your preamble

\IfFileExists{cleveref.sty}
  {\usepackage{cleveref}}
  {\let\cref\ref\newcommand\crefformat[2]{}}

and that would be all.
