I am using the versions.sty package and would like to process some text twice (or more times) in a different version configuration, but within the same document. So I use \excludeversion and \includeversion several times. Each use of these seems to define the environment with the same parameter as the name of the argument. So I get an annoying warning at every run, cluttering my LaTeX messages.

Here is a small example:








Produces the following warnings:

Package `Versions' Warning: Redefining environment `A' on input line 11.
Package `Versions' Warning: Redefining environment `B' on input line 12.

And the following output:


The output is fine. Is there a better way of doing what I am trying to achieve without this warnings?

(of course the idea is that the text that is repeated in MWE is included from the same file, so I obtain different run of latex over the same file).

  • You can either suppress the warnings, or try a different approach. Which do you want? Everybody may not be familiar with the versions package. Could you provide the expected output of your minimal example?

  • @Werner, I believe that it was an MWE already :) but I made it a tad more concrete. I would like best way to achieve multiple runs over the same sub-document, in different versions. Supressing warnings is much less interesting, unless any other alternative is awfully complex. Jan 28, 2015 at 20:32

You can suppress the warnings issued by versions by adding the following to your preamble:

\let\@Vs@envwarn\@gobble% Remove environment renewal warnings.

Alternatively the silence package does something similar:

\WarningFilter{`Versions'}{Redefining environment}

A different approach that uses \if-constructions would be:


\VersionAtrue% Include Version A
\VersionBfalse% Exclude Version B

\ifVersionA a \fi
\ifVersionB b \fi

\VersionAfalse% Exclude Version A
\VersionBtrue% Include Version B

\ifVersionA a \fi
\ifVersionB b \fi
