# messages={silent} not working with acro v2.4 package

In acro package, version v2.4 the option messages={silent} is not working as expected.

In the MWE below, the acronym is not defined. But with the option messages={silent} it should be ignored, issuing an error, but keep on with the compilation.

\documentclass{article}

\usepackage{acro}
\acsetup{messages={silent}}

\begin{document}

\ac{AAA}

\end{document}

• The error comes from deeper than acro, because it is Missing number, treated as zero, so a TeX error. It seems a bug in acro. – egreg Apr 12 '16 at 21:06
• Bug messages are best made here bitbucket.org/cgnieder/acro (and if something's not working as advertised I consider it a bug) – clemens Apr 13 '16 at 0:06
• It is easier to put them here :). I may write in the bitbucket, but I do not know exactly where. – cacamailg Apr 13 '16 at 0:16
• @cacamailg no, it's not easier – on bitbucket you can be sure that I'll see the issue and will try to find a fix. Here it is just luck that I saw your question so fast (and also that I remembered it today)… It's quite easy to find on bitbucket: click on issues and create new: bitbucket.org/cgnieder/acro/issues/new – clemens Apr 13 '16 at 9:25
• @cacamailg actually the silent option is working: using an undefined acronym issues an acro warning, not an acro error. I fixed it anyway. The new version is available on bitbucket.org/cgnieder/acro and will be uploaded to CTAN in the next days… – clemens Apr 13 '16 at 9:48

With v2.4a (2016/04/14) or newer there is no error any more.

\documentclass{article}

\usepackage{acro}[2016/04/14]
\acsetup{messages={silent}}

\begin{document}

\ac{AAA}

\end{document}

• I will need to wait for TeXLive 2016. However, I will accept your answer. Thanks for taking care of this "bug". – cacamailg May 9 '16 at 21:57
