How to use arara

Question

Hello after compiling the code found below using WinEdt 10 PDFLaTeX, I ran arara from the accessories menu but got an error I didn't get any directives in 'animated1.tex' , so didn't do anything...

Can you tell me how to use arara for this code:

%arara: animate: {density: 160, delay: 8}
\documentclass[tikz]{standalone}
\usepackage{amsmath,amssymb}
\usepackage{pgfplots}

\pgfplotsset{compat=1.13}
\usepgfplotslibrary{fillbetween}

\begin{document}
\foreach \mainangle [count=\xx, evaluate=\mainangle as \mark using (\mainangle/45)] in {0,5,...,355,360}{
\begin{tikzpicture}
\begin{axis}[
    set layers,
    x=1.5cm,y=1.5cm,
    xmin=-3.7, xmax=8.2,
    ymin=-1.5, ymax=1.5,
    axis lines=center,
    axis on top,
    xtick={2,4,6,8},
    ytick={-1,-.5,.5,1},
    xticklabels={$90^{\circ} (\pi/2)$, $180^{\circ} (\pi)$, $270^{\circ} (3\pi/2)$,$360^{\circ} (2\pi)$},
    xticklabel style={font=\tiny},
    yticklabels={-1,-0.5,0.5,1},
    ylabel={$\sin(x)$}, y label style={anchor=west},
    xlabel={$x$}, x label style={anchor=south},
]
\pgfonlayer{pre main}
\addplot [fill=white] coordinates {(-4,-2) (8.5,-2) (8.5,2) (-4,2)} \closedcycle;
\endpgfonlayer

\path[name path=xaxis] (axis cs:-4,0) -- (axis cs:8,0);
\coordinate (O) at (axis cs:0,0);

% plot and circle
\addplot [samples=100,domain=0:8, name path=myplot](\x,{3 * sin(\x*45)/pi});
\draw[name path=circle] (axis cs:-2.5,0) circle (1.5cm);

% fill in circle and plot
\draw[black,fill=blue!40] (axis cs:-2.5,0) -- (axis cs:-1.5,0) arc (0:\mainangle:1.5cm) coordinate (cc) -- cycle;
\path[name path=mark] (axis cs:\mark,-1) -- (axis cs:\mark,1);
% small circles
\draw (cc) circle (3pt);

\path[name intersections={of=mark and myplot,by=cp}];
\draw (cp) circle (3pt);
\draw (cc) -- (cp) -- (cp|-O);

\ifnum\mainangle<5
\else
\addplot[blue!30] fill between[of=xaxis and myplot, soft clip={domain=-1:\mark}];
\fi
\end{axis}
\end{tikzpicture}}
\end{document} 

Answer 1

You forgot a space in the arara directive.

The right one should be:

% arara: animate: {density: 160, delay: 8}

Remember that this directive works if you have the animate.yaml rule as in this cmhughes's answer and ImageMagick installed (during install time remember to check the option "Install legacy utilities (e.g. convert)" otherwise convert.exe won't be installed).

Also you need to have compiled the source file into .pdf otherwise the conversion cannot start.

So I suggest you to add the rule

% arara: pdflatex

before the above one and let arara do the whole work for you.

EDIT

Supposing that you're going to place your animate.yaml in the folder C:\arara\myrules, the contents of araraconfig.yaml must be

!config
paths:
- C:\arara\myrules

The file araraconfig.yaml has to be placed in the folder C:\Users\<Username>, where <Username> is your Windows User Account name.
