% \section{Making a Note Column}
%
% The package supports a various number of note columns. Each is referenced by
% a unique name.
%
% \begin{macro}{\DeclareNoteColumn}
% \begin{description}
% \item[\OParameter{option list}:] a comma-separated list of
% \texttt{\meta{key}=\meta{value}} pairs.
% \item[\Parameter{string}:] the name of the note column (must be fully
% expandable and expand to a string only).
% \end{description}
% That's the primary command for note columns. It defines everything, the note
% column needs.
% \begin{macrocode}
%<*body>
\newcommand*{\DeclareNoteColumn}[2][]{%
% \end{macrocode}
% First of all we need a box register. The contents of the note column will be
% build inside of this register. Since \eTeX{} registers shouldn't be a
% problem. User should use package \Package{etex}, if he or she runs out of
% registers. Note, that the registers will stay allocated, if the interface
% will be removed! Nevertheless, the name will be destroyed!
% \begin{macrocode}
\@ifundefined{slnc@#2@box}{%
\expandafter\newsavebox\csname slnc@#2@box\endcsname
}{}%
% \end{macrocode}
% There's also a kind of item stack of unprocessed notes for each note column.
% \begin{macrocode}
\@ifundefined{slnc@#2@unprocessed}{%
\@namedef{slnc@#2@unprocessed}{}%
}{}%
% \end{macrocode}
% Next we need a horizontal positions and a width for the note column. Neither
% the horizontal position nor the width are stretchable or shrinkable. The
% position should be variable depending on the page. So it's better to use a
% macro instead of a length. The width isn't more variable than, e.g., the
% text width. So we can use a macro too. Both will be initialised to the
% normal marginal note column later.
% \changes{3.27}{2019/02/14}{initialization of one colour stack per note
% column}%^^A
% For colour support we also need one colour stack per note column. A colour
% stack is a feature only available for pdf\TeX{} and lua\TeX{}.
% \begin{macrocode}
\@ifundefined{slnc@#2@colorstack}{%
\scr@ifundefinedorrelax{pdfcolorstackinit}{%

}%
}{%
\expandafter\chardef\csname slnc@#2@colorstack\endcsname=
\pdfcolorstackinit direct {\slnc@initial@black}%
}%
}{}%
% \end{macrocode}
% If there isn't a font element for the (new) note column, we define a new one
% and add it to the auto-remove code:
% \begin{macrocode}
\@ifundefined{scr@fnt@notecolumn.#2}{%
\@ifundefined{@notecolumn.#2font}{}{%
\PackageInfo{scrlayer-notecolumn}{using already defined
macro\MessageBreak
`\expandafter\string\csname @notecolumn.#2font\endcsname' for font
element\MessageBreak
`notecolumn.#2'%
}%
}%
\newkomafont{notecolumn.#2}{}%
}{%
\PackageInfo{scrlayer-notecolumn}{using already defined font
element\MessageBreak
`notecolumn.#2'%
}%
}%
% \end{macrocode}
% After the initialisation we process the options, that may change the initial
% values.
% \begin{macrocode}
\newcommand*{\slnc@name}{}%
\edef\slnc@name{#2}%
\FamilyExecuteOptions[.definenotecolumn]{KOMAarg}{marginpar,#1}%
\let\slnc@name\relax
% \end{macrocode}
% The values are set up, so they may be used to declare a layer.
% \begin{macrocode}
\DeclareLayer[%
foreground,%
align=tl,%
voffset=1in+\topmargin+\headheight+\headsep,%
height=\dimexpr\textheight+\topskip\relax,%
hoffset=\csname slnc@#2@pos\endcsname,%
width=\csname slnc@#2@width\endcsname,%
contents=\slnc@processnotes{#2}%
]{notecolumn.#2}
% \end{macrocode}
% We need to add the layer to every page style. The easiest way to do this is
% to add it to the pseudo layer page style \Pagestyle{@everystyle@}.
% \changes{v0.1.1681}{2014/02/05}{add the layer only once}
% \begin{macrocode}
\IfLayerAtPageStyle{@everystyle@}{notecolumn.#2}{}{%

% list.

% The initial black is the colour used to initialize the colour stacks. As long
% as only pdf\TeX{} and lua\TeX{} provide colour stacks, we can initialize it
% with \texttt{0 g 0 G}. However it may be better to use the initial
