+% \begin{abstract}
+% The |luatodonotes| package allows you to insert to--do items in your
+% document. At any point in the document a list of all the inserted
+% to--do items can be listed with the |\listoftodos| command.
+%
+% It is an extended version of the |todonotes| package and uses more advanced
+% algorithms to place the to--do notes notes on the page.
+% For this algorithms it depends on Lua\TeX.
+% \end{abstract}
+%
+% \tableofcontents
+%
+% \newpage
+% \section{Introduction}
+%
+% The |luatodonotes| package makes three commands available to the
+% user: |\todo[]{}|, |\missingfigure{}| and |\listoftodos|.
+% |\todo[]{}| and |\missingfigure{}| makes it possible to insert
+% notes in your document about things that has to be done later
+% (todonotes \ldots).
+% This package is based on version 1.0.2 of
+% |todonotes|\footnote{\url{http://www.ctan.org/pkg/todonotes}} by Henrik Skov
+% Midtiby.
+%
+% The positions of the notes on the page is determined using algorithms
+% implemented in Lua, so you have to process your documents using Lua\LaTeX.
+% The package can be used as a drop-in replacement for the original
+% |todonotes| package, you
+% only need to modify |\usepackage{todonotes}| to |\usepackage{luatodonotes}|.
+% Note that |todonotes| and |luatodonotes| must not be loaded inside the same
+% document.
+%
+% Some alternatives for the luatodonotes package are:
+% \begin{itemize}
+% \item \href{http://www.ctan.org/tex-archive/macros/latex/contrib/easy-todo}{easy-todo}\\
+% Depends on |color|, |tocloft| and |ifthen|, small feature set.
+% \item \href{http://www.ctan.org/pkg/fixmetodonotes}{fixmetodonotes}\\
+% Depends on |graphicx|, |color|, |transparent|, |watermark|, |fix-cm|, |ulem| and |tocloft|, small feature set.
+% \item \href{http://www.ctan.org/tex-archive/macros/latex/contrib/todo}{todo}\\
+% Depends on |amssymb|, medium feature set.
+% \item \href{http://www.ctan.org/tex-archive/macros/latex/contrib/fixme}{fixme}\\
+% Large package with a lot of features.
+% \item \href{http://www.ctan.org/pkg/todonotes}{todonotes}
+% \end{itemize}
+%
+% Compared to the classical todonotes this package has more advanced algorithms
+% and more configuration options to control the position of the notes on the
+% page.
+% Additionally, we are able to place notes at almost every position on the
+% page, e.\,g., in floating environments or in footnotes.
+% As a disadvantage luatodonotes requires Lua\LaTeX for document processing, so
+% a standard |pdflatex| won't work.
+% Depending on the chosen layout for the to--do notes the runtime can be much
+% higher than with todonotes.
+% Labels placed by luatodonotes can conflict with text placed with
+% |\marginpar|.
+%
+% The main reason for considering other packages is that the todonotes
+% package is quire large and relies heavily on tikz.
+% This can slow down compilation of large documents significantly.
+% The mentioned alternatives have a different feature set and does not
+% rely on tikz, which makes them require less ressoureces.
+%
+%
+% \subsection{Usage}
+% The package is loaded with |\usepackage|\oarg{options}|{luatodonotes}|.
+% Valid options are described in Section~\ref{subsecPackageOptions}.
+% Note that |todonotes| must \emph{not} be loaded.
+% You have to use |lualatex| to process your document, |pdflatex| will not
+% work.
+% The package depends on positions written to the aux-file, so you have to run
+% |lualatex| twice or even three times to get the labels and leaders for the
+% notes right.
+%
+% \DescribeMacro{\todo}
+% My \index{\todo}most common usage of the todonotes package, is to
+% insert an todonotes somewhere in a latex document.
+% An example of this usage is the command
+%
+% |\todo{Make a cake \ldots}|,
+%
+% \noindent
+% which renders like\todo{Make a cake \ldots}.
+% The |\todo| command has this structure:
+% |\todo|\oarg{options}\marg{todo text}.
+% The |todo text| is the text that will be shown in the todonote and
+% in the list of todos. The optional argument |options|, allows the
+% user to customize the appearance of the inserted todonotes.
+% For a description of all the options see section
+% \ref{subsecTodoOptions}.
+%
+% \DescribeMacro{\todoarea}
+% The |\todoarea| is similiar to |\todo|, but is able to highlight a specified
+% area in the text, to which the note is connected.
+% The command has this structure:
+% |\todoarea|\oarg{options}\marg{note text}\marg{highlighted text}.
+% This command was not tested extensively until now, so it should be used with
+% caution.
+%
+% \DescribeMacro{\missingfigure}
+% The |\missingfigure| command inserts an image containing an
+% attention sign and the given text.
+% The command takes only one argument
+% |\missingfigure|\marg{text}, a text string that could
+% describe what the figure should consist of.
+% An example of its usage could be
+%
+% |\missingfigure{Make a sketch of the structure of a trebuchet.}|
+%
+% \noindent
+% which renders like.
+%
+% \missingfigure{Make a sketch of the structure of a trebuchet.}
+%
+%
+% \DescribeMacro{\listoftodos}
+% The |\listoftodos| command inserts a list of all the todos in the
+% current document. |\listoftodos| takes no arguments.
+% For this document the list of to--do's looks like.
+% \listoftodos
+% \vspace{0.5cm}
+%
+% \DescribeMacro{\todototoc}
+% The |\todototoc| command adds an entry to the table of contents for
+% list of todos. The command should be placed right before the
+% |\listoftodos| command.
+%
+% \subsection{Package options}
+% \label{subsecPackageOptions}
+% \DescribeMacro{disable}
+% If the option |disable| is passed to the package, the macros
+% usually defined by the package (|\todo|, |\todoarea|, |\listoftodos| and
+% |\missingfigure|) are defined as macros with no effect, and thus
+% all inserted notes are removed.
+%
+% \DescribeMacro{obeyDraft, obeyFinal}
+% When the option |obeyDraft| is given, the package checks
+% if the one of the options |draft|, |draftcls| or |draftclsnofoot|
+% is given (this option is usually given to
+% the documentclass). If the |draft| option is given, the
+% functionality of the package is enabled and otherwise the effect
+% of the package is disabled.
+% The option |obeyFinal| does something similar, except that the
+% todonotes package is only disabled if the |final| option given.
+%
+% \DescribeMacro{danish, german, ngerman, french, swedish}
+% \DescribeMacro{spanish, catalan, italian}
+% \DescribeMacro{portuguese, dutch}
+% Use translations of the text strings
+% ''List of todos'' and ''Missing figure''.
+% The default is to use none of these options, which results in
+% english text strings.
+% Currently the following languages are supported:
+% catalan,
+% danish,
+% dutch,
+% french,
+% german,
+% ngerman,
+% italian,
+% portuguese,
+% spanish and
+% swedish.
+%
+% \DescribeMacro{colorinlistoftodos}
+% Adds a small colored square in front of all items in the Todo
+% list. The color of the square is the same as the fill color of the
+% inserted todonote.
+% This can be useful if there are different types of todos
+% (insert reference, explain in detail, \ldots) where the color of
+% the inserted todonote marks the type of todo.
+%
+% \DescribeMacro{color}
+% \DescribeMacro{backgroundcolor}
+% \DescribeMacro{linecolor}
+% \DescribeMacro{bordercolor}
+% These options sets the default colors for the todo command.
+% There is three colors that can be specified. The border color
+% (default |bordercolor=black|) around the inserted text, the color
+% behind the inserted text (default |backgroundcolor=orange|) and
+% the color of the line connecting the inserted textbox with the
+% current location in the text (default |linecolor=black!30|).
+% Setting the |color| option to |val| passes this value on to the
+% background and line color options.
+% The specified colors must be valid according to the
+% |xcolor| package.
+%
+% \DescribeMacro{textsize}
+% |textsize=value| sets the default text size of the inserted
+% todonotes to the given value.
+% Value is the ''name'' of the used font size, eg. if the desired
+% fontsize is |\tiny| use |textsize=tiny|. The default value is
+% |textsize=normalsize|.
+%
+% \DescribeMacro{prependcaption}
+% The |prependcaption| option triggers a special behaviour of the
+% |caption=val| option for the todo command, where the given value
+% |val| is inserted in the inserted todonote.
+%
+% \DescribeMacro{shadow}
+% If the |shadow| option is given, the inserted todonotes will be
+% displayed with a gray shadow.
+% I expect that the option will trigger problems with tikz versions
+% prior to 2.0.
+%
+% \DescribeMacro{figwidth}
+% \DescribeMacro{figheight}
+% The |figwidth=length| option and |figheight=length| option set the default
+% width and height of the figure
+% inserted by the |\missingfigure| command.
+% The default value is |\columnwidth| for the width and |4cm| for the height.
+%
+% \DescribeMacro{leaderwidth}
+% The |leaderwidth=length| option specifies the width of the leader lines.
+% The argument is passed to the |line width| option in TikZ.
+% The default value is |1.6pt|.
+%
+% \DescribeMacro{leadertype}
+% The |leadertype=type| option specifies the shape of the leaders, which are
+% drawn between the labels in the margin and the corresponding sites in text.
+% We use the characterization of the leader types known from boundary labeling:
+% $p$ denotes a segment parallel to the left/right side of the text area, while
+% $o$ denotes a orthogonal segment.
+% $s$ is a straight-line segment.
+% The following types are available (|opo| is the default value):
+% \begin{itemize}
+% \item |s|:
+% Straight-line connection between site and label.
+% \item |sBezier|:
+% Uses the straight-line leaders but transforms them into B\'ezier curves,
+% which are easier to follow for the reader.
+% The generated curves don't cross each other when the straight-line leaders
+% are crossing-free.
+% \item |opo|:
+% This is the style used in the original todonotes package.
+% The leaders start with a horizontal segment at the site in the text,
+% followed by a vertical segment in the margin beneath the text.
+% The last segment is a vertical segment, which connects to the label.
+% \item |os|:
+% This is the style used in common word processing applications like
+% LibreOffice.
+% The leader also starts with a horizontal segment that leads to the margin
+% and is connected to the label by a straight line.
+% \item |po|:
+% The leader starts with a vertical segment at the site in text and is then
+% connected to the label by a horizontal segment.
+% \end{itemize}
+%
+% \DescribeMacro{positioning}
+% The |positioning=algorithm| option specifies, which algorithm is used to
+% determine the positions of the notes on the page.
+% You should choose the algorithm depending on the leader type you want to use.
+% The default value for this option is |inputOrderStacks|.
+% The following algorithms are available:
+% \begin{itemize}
+% \item |inputOrder|:
+% Place the labels in the order given by the
+% y-coordinates of the corresponding sites in text.
+% Intended for use with $opo$- or $os$-leaders.
+% \item |inputOrderStacks|:
+% Like the algorithm before, but the labels are
+% clustered before they are placed.
+% Thus the labels are placed nearer to their sites.
+% Intended for use with $opo$- or $os$-leaders.
+% \item |sLeaderNorthEast|:
+% Places labels in a way that they can be connected to their sites by
+% straight-line leaders without crossings.
+% The leaders are attached to the upper right or upper left corner of the
+% label (depending on which site of the text the label is placed).
+% Intended for use with $s$-leaders or B\'ezier leaders.
+% \item |sLeaderNorthEastBelow|:
+% Like the algorithm before, but the leader is attached to a point that is a
+% constant offset below the corner of the label.
+% Intended for use with $s$-leaders or B\'ezier leaders.
+% \item |sLeaderNorthEastBelowStacks|:
+% Like the algorithm before, but the labels are cluster before they are
+% placed.
+% Thus the labels are placed nearer to their sites.
+% Intended for use with $s$-leaders or B\'ezier leaders.
+% \item |sLeaderEast|:
+% Like the algorithms before, but the leader is attached to the center of the
+% right or left boundary of the label.
+% Intended for use with $s$-leaders or B\'ezier leaders.
+% \item |poLeaders|:
+% Calculates label positions that lead to $po$-leaders with minimum total
+% length.
+% This algorithm depends heavily on the number of notes, so the runtime and
+% memory consumption can get very high.
+% \item |poLeadersAvoidLines|:
+% Like the algorithm before, but tries to avoid overlapping of horizontal
+% leader segments with text.
+% This algorithm depends heavily on advanced Lua\TeX\ features to manipulate
+% the data structures of the page, so it possibly could give conflicts with
+% other packages.
+% \end{itemize}
+%
+% \DescribeMacro{splitting}
+% The |splitting=algorithm| option can be used to place the labels on both sides
+% of the text.
+% The notes are only separated when there is enough space on both sides (see
+% |minNoteWidth|.
+% The default value for this option is |none|.
+% Available algorithms for this option are:
+% \begin{itemize}
+% \item |none|:
+% Labels are placed in the wider margin only.
+% \item |middle|:
+% The text area is split in the middle in a left and a right half.
+% Labels, whose sites are in the left half of the text, are placed in the
+% left margin, the others in the right margin.
+% \item |median|:
+% The notes are seperated at the median of the sites (sorted by
+% x-coordinate).
+% That is, the number of notes in the left and the right margin is equal
+% (except for one note).
+% \item |weightedMedian|:
+% Considers the height of the labels for the median.
+% So the total height of the labels in the left margin is approximately equal
+% to that in the right margin.
+% \end{itemize}
+%
+% \DescribeMacro{interNoteSpace}
+% The |interNoteSpace=length| option specifies the minimum vertical distance
+% between two notes.
+% The default value is |5pt|.
+%
+% \DescribeMacro{noteInnerSep}
+% The |noteInnerSep=length| option specifies the |inner sep| used for the TikZ
+% nodes, i.\,e., the distance between the border of the note and the text inside
+% it.
+% The default value is |5pt|.
+%
+% \DescribeMacro{routingAreaWidth}
+% The |routingAreaWidth=length| option specifies the width of the so called
+% routing area.
+% This is the area, in which the vertical segment of $opo$-leaders are placed.
+% The area is also used for $os$-leaders.
+% The default value is |0.4cm|.
+%
+% \DescribeMacro{minNoteWidth}
+% The |minNoteWidth=length| option specifies the minimum width of the labels.
+% When there is fewer space in one of the margins, this margin is not considered
+% for label placement.
+% If both margins are narrower, no labels are placed and an error message is
+% printed to the console output.
+% The default value of this option is |2.0cm|.
+%
+% \DescribeMacro{distanceNotesPageBorder}
+% The |distanceNotesPageBorder=length| option specifies the horizontal distance
+% from the labels to the borders of the paper.
+% You can adjust this setting to your printer margins.
+% The default value of this option is |0.5cm|.
+%
+% \DescribeMacro{distanceNotesText}
+% The |distanceNotesPageBorder=length| option specifies the horizontal distance
+% between the labels and the text area.
+% With $opo$- or $os$-leaders the routing area is inserted additionally so the
+% distance between labels and text area increases.
+% The default value of this option is |0.2cm|.
+%
+% \DescribeMacro{rasterHeight}
+% The |rasterHeight=length| option is used only for the $po$-leader algorithm.
+% For this algorithm the page is rasterized and the labels are placed only on
+% the positions given by this raster.
+% Decreasing this value can yield better results (i.\,e., smaller total leader
+% length), but strongly increases the runtime and memory consumption.
+% The default value of this option is |1cm|.
+%
+% \DescribeMacro{debug}
+% When the |debug| option is activated the package is more verbose on
+% the commandline.
+% Additionally, some markers, which can be used to understand the algorithms,
+% are drawn on the page (depending on the chosen algorithm).
+%
+%
+%
+%
+% \subsection{Options for the todo command}
+% \label{subsecTodoOptions}
+% There are several options that can be given to the |\todo|
+% command. All the options are described here and often I have
+% included examples of the change in visual appearance.
+% Default values for these options can be set using the presetkeys
+% command.
+% \begin{verbatim}
+% \presetkeys{todonotes}{fancyline, color=blue!30}{}
+% \end{verbatim}
+%
+% \DescribeMacro{disable}
+% The |disable| option can be given directly to the todo command.
+% If given the command has no effect.
+%
+% \DescribeMacro{color}
+% \DescribeMacro{backgroundcolor}
+% \DescribeMacro{linecolor}
+% \DescribeMacro{bordercolor}
+% These options set the color that is used in the current todo
+% command.
+% The color classes is the same as used in the color package
+% options, see section \ref{subsecPackageOptions}.
+% Default values can be set by the color
+% options when the todonotes package is loaded.
+% \todo[color=green!40]{And a green note}
+% The todo notes inserted in this paragraph is created with the
+% command
+% |\todo[color=green!40]{And a green note}|.
+% The color of the inserted note could be used to mark different
+% types of tasks (insert references, explain something in detail,
+% \ldots), this could be streamlined by defining new commands like
+% below.
+% \begin{verbatim}
+% \newcommand{\insertref}[1]{\todo[color=green!40]{#1}}
+% \newcommand{\explainindetail}[1]{\todo[color=red!40]{#1}}
+% \end{verbatim}
+% An example that uses all of the color options is given below
+% \todo[linecolor=green!70!white, backgroundcolor=blue!20!white,
+% bordercolor=red]{Anything but default colors}.
+% \begin{verbatim}
+% \todo[linecolor=green!70!white, backgroundcolor=blue!20!white,
+% bordercolor=red]{Anything but default colors}.
+% \end{verbatim}
+%
+%
+% \DescribeMacro{line / noline}
+% If you want to get rid of the line connecting the inserted note
+% with the place in the text where the note occurs in the latex
+% code, the option |noline| can be used.
+% \todo[noline]{A note with no line connecting it to the placement
+% in the original text.}
+% |\todo[noline]{A note with no line ...}|
+% \vspace{1.0cm}
+%
+%
+% \DescribeMacro{inline / noinline}
+% It is possible to place a todonote inside the text instead of
+% placing it in the margin, this could be desirable if the text in
+% the note has a considerable length.
+% |\todo[inline]{A todonote placed in the text}|
+% \todo[inline]{A todonote placed in the text}
+
+% \begin{wrapfigure}[1]{r}[20mm]{40mm}
+% \begin{tikzpicture}
+% \draw[red] (0, 0) circle(0.45);
+% \draw[green] (1, 0) circle(0.45);
+% \draw[blue] (2, 0) circle(0.45);
+% \end{tikzpicture}
+% \caption{A text explaining the image.
+% \todo[inline]{Fill those circles \ldots}}
+% \end{wrapfigure}
+% Another usage for the inline option is when you want to add a
+% todonote to a figure caption.
+%
+% \begin{verbatim}
+% \begin{wrapfigure}{r}[20mm]{40mm}
+% \begin{tikzpicture}
+% \draw[red] (0, 0) circle(0.45);
+% \draw[green] (1, 0) circle(0.45);
+% \draw[blue] (2, 0) circle(0.45);
+% \end{tikzpicture}
+% \caption{A text explaining the image.
+% \todo[inline]{Fill those circles \ldots}}
+% \end{wrapfigure}
+% \end{verbatim}
+%
+% \DescribeMacro{size}
+% |size=val| changes the size of the text inside the todonote.
+% The commands used to create the notes below are \\ \noindent
+% |\todo[size=\Large]{A note with a large font size.}|
+% and \\ \noindent
+% |\todo[inline, size=\tiny]{Note with very small font size.}|.
+% \todo[size=\Large]{A note with a large font size.}
+% \todo[inline, size=\footnotesize]{Note with very small font size.}
+%
+% \DescribeMacro{list / nolist}
+% When the option |nolist| is given, the todo item will not appear in
+% the list of todos.
+%
+% \DescribeMacro{caption}
+% The |caption| option enables the user to specify a short
+% description of the todonote that are inserted in the list of
+% todos instead of the full todonote text.
+% \todo[caption={Short note}]{A very long and tedious note that
+% cannot be on one line in the list of todos.}
+% \begin{verbatim}
+% \todo[caption={Short note}]{A very long and tedious note that
+% cannot be on one line in the list of todos.}.
+% \end{verbatim}
+% The effect of this option is altered with the package option
+% |prependcaption| or the |prepend| / |noprepend| option for the
+% todo command.
+%
+% \DescribeMacro{prepend / noprepend}
+% The options |prepend| and |noprepend| can be used for setting
+% whether a given caption should be prepended to the todonote or
+% not.
+% Globally this can be set using the |prependcaption| option for the
+% package.~\todo[prepend, caption={Short note with prepend}]{A very
+% long and tedious note that cannot be on one line in the list of
+% todos.} Below is the effect of the option shown using the code:
+% \todo[noprepend, caption={Short note with noprepend}]{A very long
+% and tedious note that cannot be on one line in the list of
+% todos.}
+% \begin{verbatim}
+% \todo[prepend, caption={Short note with prepend}]{A very long and tedious
+% note that cannot be on one line in the list of todos.}.
+% \todo[noprepend, caption={Short note with noprepend}]{A very long and
+% tedious note that cannot be on one line in the list of todos.}.
+% \end{verbatim}
+%
+% \DescribeMacro{author}
+% The |author| option takes a parameter, the name of the author.
+% The given name is inserted in the todonote.
+% \todo[author=Xavier]{Testing author option.}
+% \todo[author=Xavier, inline]{Testing author option.}
+% \begin{verbatim}
+% \todo[author=Xavier]{Testing author option.}
+% \todo[author=Xavier, inline]{Testing author option.}
+% \end{verbatim}
+%
+% \subsection{Options for the missingfigure command}
+%
+% \DescribeMacro{figwidth}
+% The |figwidth=length| option sets the width of the figure inserted by the
+% |\missingfigure| command.
+% Length values below $6cm$ might trigger some problems with the
+% visual appearance.
+% Try to compare the default of the missing figure command, when the
+% option is given or not.
+% \begin{verbatim}
+% \missingfigure[figwidth=6cm]{Testing a long text string}
+% \end{verbatim}
+% \missingfigure[figwidth=6cm]{Testing a long text string}
+% \begin{verbatim}
+% \missingfigure{Testing a long text string}
+% \end{verbatim}
+% \missingfigure{Testing a long text string}
+% \begin{wrapfigure}{r}[2cm]{6cm}
+% \missingfigure[figwidth=6cm]{Add a test image \ldots}
+% \end{wrapfigure}
+% Another usage of the option is when |\missingfigure| is used in
+% the wrapfigure environment.
+% \begin{verbatim}
+% \begin{wrapfigure}{r}[2cm]{6cm}
+% \missingfigure[figwidth=6cm]{Add a test image \ldots}
+% \end{wrapfigure}
+% \end{verbatim}
+%
+% \DescribeMacro{figheight}
+% The |figheight=length| option changes the height of the inserted
+% missing figure.
+% The default height is 4cm and using values lower than this might
+% cause the warning sign to pop out of the gray area.
+% \begin{verbatim}
+% \missingfigure[figheight=6cm]{Testing a long text string}
+% \end{verbatim}
+% \missingfigure[figheight=6cm]{Testing}
+%
+%
+% \subsection{Options for the listoftodos command}
+% The |\listoftodos| command takes one optional argument, that
+% defines the name of the inserted list of todos.
+% \begin{verbatim}
+% \listoftodos[I can be called anything]
+% \end{verbatim}
+%
+%
+%
+% \subsection{Known issues}
+% \subsubsection{Package loading order}
+% The luatodonotes package requires the following packages:
+% \begin{multicols}{2}
+% \begin{itemize}
+% \item ifthen
+% \item xkeyval
+% \item xcolor
+% \item tikz
+% \item graphicx (is loaded via the tikz package)
+% \item luacode
+% \item luatex
+% \item atbegshi
+% \item xstring
+% \item zref-abspage
+% \item ifoddpage
+% \item soul
+% \item soulpos
+% \end{itemize}
+% \end{multicols}
+% \noindent
+% When luatodonotes are loaded in the preamble, the package checks
+% if these packages all are loaded. If that is not the case it loads
+% the missing packages with no options given.
+% If you want to give some specific options to some of these
+% packages, you have to load them \emph{before} the luatodonotes
+% package, otherwise you will get an ''Option clash'' error when
+% latex works on the document.
+%
+% If both the menukeys and the xcolor (with the option \verb!table!)
+% package should be loaded, the following order must be used.
+% \begin{verbatim}
+%\usepackage[table]{xcolor}
+%\usepackage{todonotes}
+%\usepackage{menukeys}
+% \end{verbatim}
+%
+% \subsubsection{Spacing around inserted notes}
+% Inserted todo commands will eat the white space after the command.
+% \begin{verbatim}
+%Testing\todo{Does this eat the space?} testing
+% \end{verbatim}
+%
+% Testing\todo{Does this eat the space?}testing
+%
+%
+% \subsubsection{Conflicts with the amsart documentclass}
+% The |amsart| document class redefines some internal commands that
+% is used by the todonotes package, this will cause an malfunctioning
+% |\listoftodos| command.
+% The following code to circumvent the problem was given by Dan
+% Luecking on comp.text.tex
+% \begin{verbatim}
+% \makeatletter
+% \providecommand\@dotsep{5}
+% \makeatother
+% \listoftodos\relax
+% \end{verbatim}
+%
+% NOT TESTED
+% NOT TESTED
+% NOT TESTED
+%
+% Dominique suggests the following workaround.
+% \begin{verbatim}
+% \makeatletter
+% \providecommand\@dotsep{5}
+% \def\listtodoname{List of Todos}
+% \def\listoftodos{\@starttoc{tdo}\listtodoname}
+% \makeatother
+% \end{verbatim}
+%
+%
+%
+% \subsubsection{Unknown option ''remember picture''}
+% If latex throws the error
+% \begin{verbatim}
+% Package tikz Error: I do not know what to do with the option ``remember picture''.
+% \end{verbatim}
+% It probably means that your latex installation is outdated, as
+% only newer versions of latex driver for tikz supports the
+% |remember picture| option.
+% For additional info consult
+% ''Section 9.2.2 Producing PDF Output'' in the tikz manual.
+% \url{http://www.ctan.org/tex-archive/graphics/pgf/base/doc/generic/pgf/pgfmanual.pdf}
+%
+%
+%
+% \subsubsection{List of todo heading is not correctly formatted}
+% If using natbib, the todonotes list title gets screwed up unless
+% you do something like this:
+% \begin{verbatim}
+% \makeatletter\let\chapter\@undefined\makeatother
+% \end{verbatim}
+% Suggestion by Richard Stanton.
+%
+%
+%
+% \subsubsection{Some commands not working inside notes}
+% Some commands will not work like expected, when used inside of a note.
+% They will cause errors when processing the document or have simply no effect.
+% This is caused by the mechanism used to layout the notes:
+% The content is written into a hbox when a |\todo| is encountered.
+% The contents of this box are then stored until the note is typeset.
+% By that time the contents are taken out of the hbox (by |\unhbox|) and put
+% into a |\parbox| with the width required for the note.
+% I don't have a solution for this problem yet.

+% \subsection{Initialisation of our Lua code}
+% In this part we define some of the variables used by Lua depending on the
+% package options and do some other initialisation tasks.
+%
+% We first need some temporary dimensions, which are written by \TeX\ and read
+% from Lua.
+% We use dimensions here because it is easier to access \TeX\ dimensions from
+% Lua than \LaTeX\ lengths.
+% We use |tex.dimen| in Lua to access dimensions.
+% The first dimensions are used when extracting the absolute coordinates of a
+% position on the page.
+% \begin{macrocode}
+\newdimen\@todonotes@extractx
+\newdimen\@todonotes@extracty
+% \end{macrocode}
+% The following savebox and dimensions are used to calculate the height of a
+% certain label.
+% The box and dimensions are filled by \TeX\ and then read from Lua.
+% \begin{macrocode}
+\newsavebox\@todonotes@heightcalcbox
+\newdimen\@todonotes@heightcalcboxdepth
+\newdimen\@todonotes@heightcalcboxheight
+% \end{macrocode}
+% The following savebox is used to store the contents of a note and is then
+% read from Lua.
+% \begin{macrocode}
+\newsavebox\@todonotes@notetextbox
+% \end{macrocode}
+% The following dimensions are used to read |\baselineskip| and
+% |\f@size| from Lua.
+% Dimension |\@todonotes@currentsidemargin| is set to the left margin,
+% i.\,e., to the value of length |\oddsidemargin| or
+% |\evensidemargin| depending on the type page.
+% \begin{macrocode}
+\newdimen\@todonotes@baselineskip
+\newdimen\@todonotes@fontsize
+\newdimen\@todonotes@currentsidemargin
+% \end{macrocode}
+% Loading our main Lua file.
+% \begin{macrocode}

+ \PackageWarningNoLine{luatodonotes}
+ {Invalid value for parameter leadertype: \@todonotes@leadertype}]
+% \end{macrocode}
+% The following commands are used to detect the absolute positions of lines on
+% the page.
+%
+% We first need to define a command to be able to insert the position from
+% |\pdflastypos| into a write-whatsit in Lua.
+% We need this workaround because we cannot insert |\pdflastypos| directly into
+% the tokenlist in the Lua callback \texttt{callbackOutputLinePositions()}.
+% \begin{macrocode}
+\def\@todonotes@pdflastypos{\the\pdflastypos}
+% \end{macrocode}
+% The following commands are written to the temporary \texttt{lpo}-file.
+% When reading this file we call a Lua function for each line in the file and
+% thus can collect the line positions in a Lua table.
+% \begin{macrocode}
+\newcommand{\@todonotes@lineposition}[3]{%
+ \directlua{linePositionsAddLine(#1,#2,#3)}%
+}
+\newcommand{\@todonotes@nextpage}{%
+ \directlua{linePositionsNextPage()}%
+}%
+% \end{macrocode}
+% The following macro is used in \texttt{AtBeginShipout} to signal in the
+% \texttt{lpo}-file that a new page is started.
+% \begin{macrocode}
+\newcommand{\@todonotes@writeNextpageToLpo}{%
+ \ifdefined\tf@lpo%
+ \immediate\write\tf@lpo{\@backslashchar @todonotes@nextpage}%
+ \fi
+}
+% \end{macrocode}
+% Depending on the debug-option of the package we set the corresponding Lua
+% variable here.
+% Additionally, we prepare to print our notes and leaders in foreground when in
+% debug mode.
+% \begin{macrocode}
+\if@todonotes@debugenabled
+ \directlua{todonotesDebug = true}
+ \newcommand{\@todonotes@AtBeginShipoutUpperLeft}
+ {\AtBeginShipoutUpperLeftForeground}
+\else
+ \directlua{todonotesDebug = false}
+ \newcommand{\@todonotes@AtBeginShipoutUpperLeft}
+ {\AtBeginShipoutUpperLeft}
+\fi
+% \end{macrocode}
+% Initialise the script when all Lua variables are set according to the package
+% options.
+% \begin{macrocode}
+\directlua{initTodonotes()}
+% \end{macrocode}
+% Some definitions to highlight areas in text.
