% \begin{abstract}
% A small package originally based on \href{https://tex.stackexchange.com/a/241139/}{Harish Kumar's answer} to a question I asked on \TeX{} SE\footnote{%
%   See \href{https://tex.stackexchange.com/a/241139/}{tex.stackexchange.com/a/241139/}.% 
% }.
% The intended purpose was the creation of worksheets for students where I would like \LaTeX{} to use the available vertical space to provide lined areas for answers.
% Since then, the code has been (partially) rewritten in \pkg{expl3} and extended in response to both my own needs and others' questions on \TeX{} SE.
% The package aims to do one thing: to fill a vertical space in the same way as, say, \verb|\vfill|, but with some kind of 窶惑iller窶� rather than empty space.
% Currently, the package supports solid rules or dotted lines.
% The remainder of the current line may optionally be filled in the same way and the 窶惑iller窶� may be coloured if desired.
% 
% Lines may optionally be numbered, though the numbered versions should not be used to fill long stretches as they are extremely inefficient.
% \textbf{Numbered fills are highly experimental and not recommended for use in 窶腕eal窶� documents.}
% That is, it seems to work, but I recommend using an alternative package or solution if you need a reliable numbering mechanism.
% \end{abstract}
% 
% \section{Load}\label{sec:pkg}
% To use the package simply load it in your preamble in the usual way.
%

% \fi
%
% A small number of options may be specified when loading the package.
% See \cref{sec:config}.
%
% We start with an example in \cref{sec:ee}.
% \Cref{sec:use} describes the basic commands illustrated in this example.
% \Cref{sec:config} explains the options used by these commands, together with other customisation features of \pkg{fillwith}.
%
% \section{Example}\label{sec:ee}
%
% The code below illustrates most package features.
%
% \Cref{fig:ee1} demonstrates filling with rules.
% Note the effect of altering \texttt{fillwith ht} on line-spacing.
% \begin{figure}
%   \centering
%   \fbox{\includegraphics{fillwith-example.pdf}}
%   \caption{Filling with rules.}\label{fig:ee1}
% \end{figure}
%
% \Cref{fig:ee2} shows dotted fillings.
% Note the use of \cmd{\fillwithset} to alter the colour.
% \begin{figure}
%   \centering
%   \fbox{\includegraphics[page=2]{fillwith-example.pdf}}
%   \caption{Filling with dotted lines.}\label{fig:ee2}
% \end{figure}
%
% \Cref{fig:ee3} shows numbered fillings.
% Note the use of \texttt{goal ht} to divide the available vertical space more-or-less equally. 
% \begin{figure}
%   \centering
%   \fbox{\includegraphics[page=3]{fillwith-example.pdf}}
%   \caption{Filling with numbered lines.}\label{fig:ee3}
% \end{figure}
% 
% \verbatiminput{fillwith-example.tex}
% 
% \section{Usage}\label{sec:use}
%
% \DescribeMacro{\fillwith}\oarg{options}
% \DescribeMacro{\fillwith*}
% 
% Fill vertically with current settings, optionally modified by \meta{options}.
% See \cref{sec:config} for \meta{options}.
% If used in the middle of a line, the starred form fills to the end of the line first, whereas the unstarred form does not.
%
% \DescribeMacro{\fillwithrules}\oarg{line-spacing}
% \DescribeMacro{\fillwithrules*}
%
% Convenience wrappers which just set \texttt{style = rules} and set the line-spacing to \meta{line-spacing}.
% These macros do nothing which cannot be done using \cmd{\fillwith} and \cmd{\fillwith*}.
% 
% \DescribeMacro{\fillwithdottedlines}\oarg{line-spacing}
% \DescribeMacro{\fillwithdottedlines*}
%
% Convenience wrappers which just set \texttt{style = dots} and set the line-spacing to \meta{line-spacing}.
% These macros do nothing which cannot be done using \cmd{\fillwith} and \cmd{\fillwith*}.
% 
% \DescribeMacro{\fillwithnolines}\oarg{options}
% \DescribeMacro{\fillwithnolines*}
%
% Fill vertically with current settings, numbering each complete line, after optionally setting \meta{options}.
% Numbering \textbf{requires} use of these commands, as opposed to the generic \cmd{\fillwith}/\cmd{\fillwith*}.
% 
% \section{Customisation}\label{sec:config}
%
% Options can be set per use, locally or globally.
% A small number of options are implemented as package options (\cref{sec:pkg}).
%
% \DescribeMacro{\fillwithset}\marg{options}
% Set local or global defaults.
% 
% \DescribeOpt{colour}\val{colour name}
% \DescribeOpt{color}
% \DescribeOpt{lliw}
%
% Colour to be used for (solid) rules.
%
% Initially \texttt{gray}.
% Available as a package option.
%
% \DescribeOpt{dotted color}\val{colour name}
% \DescribeOpt{dotted colour}
%
% Colour to be used for dotted lines.
%
% Initially \texttt{black}.
% Available as a package option.
%
% \DescribeOpt{cont}\vals{true,false}
%
% Whether to fill the remainder of any current line.
% Generally, users will probably prefer to use the starred command forms for local usage, but this option permits modification of the package default on a local or global basis.
%
% Initially \texttt{false}.
% Default is \texttt{true}.
%
% \DescribeOpt{fillwith~ht}\val{real positive number expressed as decimal}
%
% Multiplication factor for line-spacing.
% Typically, hand-written content requires greater spacing than typewritten content.
% This option scales the standard line-spacing.
%
% Initially \texttt{2}, which is also the default value.
% Decimal values such as \texttt{1.5} are permitted.
%
% \DescribeOpt{goal ~ ht}\val{dimension}
%
% Used only by \cmd{\fillwithnolines} and \cmd{\fillwithnolines*}.
% Sets the target dimension to fill with numbered lines.
% If unspecified, the code tries to fill the remaining vertical space on the current page.
% If more than one use of a \pkg{fillwith} macro is used on a single page, this option \textbf{must} be used for numbered fills to prevent a single instance taking (almost) all available space.
% In contrast, multiple unnumbered fills can coexist on the same page without issue --- the available space will simply be divided equally between them.
%
% Initially unset.
% No default.
%
% \DescribeOpt{no ~ font}\val{font switches}
%
% Font switches to apply when typesetting numbers for numbered fills.
%
% Initially \cmd{\normalfont}\cmd{\normalsize}, which is also the default value.
% Note the commands used here should be switches rather than text commands -- for example, use \cmd{\bfseries} rather than \cmd{\textbf} --- since the commands should not expect an argument.
%
% \DescribeOpt{style}\vals{rule,dots,line,lines,rules}
%
% Style of fill.
% \texttt{rule}, \texttt{line}, \texttt{rules} and \texttt{lines} are synonyms which all denote solid rules or lines.
% \texttt{dots} uses dotted lines rather than solid rules.
% The dots are slightly more densely packed than the standard used for dotted fills by the standard classes, as these seem a bit too widely spaced to provide ideal guidelines.
%
% Initially \texttt{dots}, which is also the default value.
%
% If an unknown value is used, the code will attempt to use two macros derived from that value.
% The first is constructed simply by preceding \meta{value} with a backslash and the second by also appending \texttt{part}.
% For example, if \texttt{style}\val{mystyle} is used, the code will try to use \cs{mystyle} and \cs{mystylepart} for complete and partial lines.
% In theory, this supports filling with somewhat arbitrary content, but the implementation is untested and \textbf{should not be used in real documents}.
