# suppress lot/lof entry in memoir

Using the caption package, one can suppress lot/lof entry with an empty optional argument for \caption. But the caption package is incompatible with memoir. How can I suppress lot/lof entries in memoir?

The caption pacakge is not incompatible with memoir, works just fine with it. memoir issues a warning telling users that when they use caption, memoir's own interface for configuring captions will no longer have any affect. –  daleif Jul 31 '12 at 13:34
The problem is: I'm working on my ctable package, which has an option cap= to set the entry for lot/lof. If it't empty, no entry should be made, like in the caption package. I can, of course \RequirePackage{caption} in ctable, but that would deprive memoir+ctable users of memoir's own caption facilities. –  Wybo Dekker Jul 31 '12 at 15:55
There are pros and cons. I do it myself in one of my packages, require caption, because it can do stuff that memoir will not get close to any time soon. Plus I use caption for all my projects, eventhough I maintain memoir –  daleif Jul 31 '12 at 20:51
Why not make some of these features plugable, such that users can change them, think of callbacks. –  daleif Jul 31 '12 at 20:53
Thanks for all comments - I finally decided not to \Require caption inside ctable but let it to the user to do so. If he uses an empty cap option a warning will be issued suggesting caption inclusion. –  Wybo Dekker Aug 2 '12 at 19:51

After daleif's comment, you can use the caption package and its list=no option:

\documentclass{memoir}
\usepackage{caption}

\begin{document}
\listoffigures

test text

\begin{figure}
\captionsetup{list=no}
\centering
\rule{3cm}{2cm}
\caption{A numbered and named caption}
\end{figure}

\begin{figure}
\centering
\rule{3cm}{2cm}
\caption*{An unnumbered and unnamed caption}
\end{figure}

\end{document}


Another option, within memoir, is to use \legend or \namedlegend:

\documentclass{memoir}

\begin{document}
\listoffigures

test text

\begin{figure}
\centering
\rule{3cm}{2cm}
\legend{A unnumbered and unnamed caption}
\end{figure}

\begin{figure}
\centering
\rule{3cm}{2cm}
\namedlegend{A unnumbered but named caption}
\end{figure}

\begin{figure}
\stepcounter{figure}
\centering
\rule{3cm}{2cm}
\legend{\figurename~\thefigure: A named and numbered caption}
\end{figure}

\end{document}


Another option is to define a command to change the lotdepth counter (lofdepth, in the case of figures) typeset the caption using the standard \caption command and then restoring the default value for the counter:

\documentclass{memoir}

\newcommand\NLcaption[1]{%
\caption{#1}%

\begin{document}

\listoftables
Test text
\begin{table}
\NLcaption{Test caption}
\end{table}

\end{document}

See my comment to daleif above. I can, of course detect memoir and then use \legend instead of \caption, but it's argument would probably have to be more complicated than "\figurename~\thefigure: "? For example, the : would not honor any setting of \captiondelim. –  Wybo Dekker Jul 31 '12 at 16:01
@WyboDekker yes, obviously the label used in my example has to use \captiondelim` (and other settings). I've added a new option to my answer providing another possibility that will honor the settings for standard captions. –  Gonzalo Medina Jul 31 '12 at 17:49
