# Short version

Is it possible to use standalone to produce externally my figures with overlays and include them directly in my main document ?

# More details

Using the answers of the question Beamer overlays, tikz external and custom file name and Integrating latexmk and TikZ external mode=list and make I have been able to outsource my Tikz pictures while using overlay.

More precisely, I have the following tex files

% tikz/fig.tex

\begin{tikzpicture}transform canvas={scale=0.5}

\node[visible on=<1->]  at (0,0) {Overlay 1};

\node[visible on=<2>]  at (2,0) {Overlay 2};

\end{tikzpicture}

% main.tex

\usepackage{tikz}
\usetikzlibrary{external}
\tikzexternalize[mode=list and make,prefix=tikz/]
\tikzset{
invisible/.style={opacity=0},
visible on/.style={alt={#1{}{invisible}}},
alt/.code args={<#1>#2#3}{%
\alt<#1>{\pgfkeysalso{#2}}{\pgfkeysalso{#3}} % \pgfkeysalso doesn't change the path
},
}
\makeatletter
\newcommand*{\overlaynumber}{\number\beamer@slideinframe}
\tikzset{
beamer externalizing/.style={%
execute at end picture={%
\tikzifexternalizing{%
\ifbeamer@anotherslide
\pgfexternalstorecommand{\string\global\string\beamer@anotherslidetrue}%
\fi
}{}%
}%
},
external/optimize=false
}
\let\orig@tikzsetnextfilename=\tikzsetnextfilename
\renewcommand\tikzsetnextfilename[1]{\orig@tikzsetnextfilename{#1-\overlaynumber}}
\makeatother

\tikzset{every picture/.style={beamer externalizing}}

\begin{document}
\begin{frame}{Example}
\begin{figure}
\only<1>{\tikzsetnextfilename{fig}}
\only<2>{\tikzsetnextfilename{fig}}
\input{tikz/fig.tikz}
\end{figure}
\end{frame}
\end{document}


Then, I can use latexmk with the following .latexmkrc

our %externalflag = ();

$lualatex = 'internal mylualatex %O %S %B'; sub mylualatex { print "Hello world\n"; our %externalflag; my$n = scalar(@_);
my @args = @_[0 .. $n - 2]; my$base = $_[$n - 1];

system 'lualatex', @args;
if ($? != 0) { return$?
}
if ( !defined $externalflag->{$base} ) {
$externalflag->{$base} = 1;
system ("$make -j8 -f$base.makefile");
}
return \$?;
}


and it will produce all the figures (in my example two because I have two overlays) in parallel using make. The only issue now is that I would like to use standalone to be able to work directly on my picture and not recompiling the whole document each time.

I saw in the doc of standalone that it should be possible to generate frames with standaloneframe, but it is not really what I want since I want only pictures, and I did not succeed in including the resulting frame in my main document using \includestandalone anyway.

• The issue then is can I produce automatically all the pdf I need using standalone with overlay ? – Pierre Marchand Apr 25 at 13:12
• Ah, you are using the beamer version of tikz. Note that each overlay is a separate image/page, whereas standalone typically generates only one image/page. – John Kormylo Apr 25 at 13:21
• Exactly, so I wonder if there is a way to get pass this. For example, I know that you can produce a frame for each overlay version of the your page using standaloneframe (but I did not succeed in outsourcing this). Or may be there is some trick to produce several pdf and include them like I did with external and Tikz – Pierre Marchand Apr 25 at 13:26
• Does it help? tex.stackexchange.com/a/168705/1952 – Ignasi Apr 25 at 14:25
• It is a nice workaround to produce several frames, good to know thanks ! But my main question is more about pictures, rather than frames. – Pierre Marchand Apr 25 at 14:33
