+multicolrule - Decorative rules between columns
+=================================================
+
+The multicolrule package lets you customize the appearance of
+the vertical rule that appears between columns of multicolumn
+text. It is primarily intended to work with the multicol
+package, hence its name, but it also supports the twocolumn
+option and \twocolumn macro provided by the standard classes
+(and related classes such as the KOMA-Script equivalents).
+
+Installation
+------------
+
+This package is provided as a .dtx file. To install it and
+compile the documentation at the same time, simply process the
+.dtx file with LaTeX (for example, `pdflatex multicolrule.dtx`).
+To extract the package only, process the file with TeX
+(`tex multicolrule.dtx`). If you have trouble compiling the
+index for the documentation, note that the documentation uses
+the l3doc class to index the code, and so the makeindex command
+should be the following:
+
+`makeindex -s gind.ist -o multicolrule.ind multicolrule.idx`
+
+This package requires LaTeX3 support to run, and compiling the
+documentation requires a variety of other packages, all of which
+are available on CTAN and any modern installation (TeX Live,
+MiKTeX, etc.).

+% The \mcrule{} package lets you customize the appearance of the vertical rule
+% that appears between columns of multicolumn text. It is primarily intended to
+% work with the \pkg{multicol} package, hence its name, but it also supports
+% the twocolumn option and \cs{twocolumn} macro provided by the standard
+% classes (and related classes such as the KOMA-Script equivalents).

+%
+%\begin{multicols}{2}[\section{Introduction}]
+%\SetMCRule{line-style=dashed}
+%  
+% In\stydsc{line-style=dashed} \LaTeX, there are two lengths that control the
+% formatting between columns of multicolumn text: \cs{columnsep} specifies the
+% space between adjacent columns, and \cs{columnseprule} specifies the width of
+% a solid vertical rule that is placed centered between the columns. The
+% \pkg{multicol} package adds the ability to change the color of the rule, but
+% in both vanilla \LaTeX{} and \pkg{multicol}, the rule itself is drawn
+% directly inside the routines that output the column boxes, and is therefore
+% difficult for users to alter.
+%
+% Of course it's a legitimate question why anyone should \emph{want} to change
+% this rule, or indeed use one at all, as good typography tends to avoid using
+% large vertical lines.\footnote{See, for example, the remarks in the
+% documentation for the \pkg{booktabs} package} In my own case, I needed to
+% modify the rule because of the requirements of a particular style I was
+% imitating, and having done the hard work of creating the necessary
+% infrastructure for one line style, it was simple to extend the solution to a
+% more general case. I hope someone else will find the options here useful.
+%
+% Note---in case it isn't obvious yet---that this guide illustrates the basic
+% line styles that \mcrule{} makes available throught the document. The default
+% line-width is 0.4pt (thin), and the default color is \texttt{Maroon}. You can
+% find examples of rules created with all available options in the file
+% \file{mcrule-example.pdf}.
+% \end{multicols}
+%
+% \begin{multicols}{2}[\subsection{Bugs and Known Limitations}]
+% As\stydsc{line-style=dots} this is the first release of this package, there
+% are likely bugs that remain to be uncovered, as well as missing features and
+% inefficient methods that should be improved upon. The development code is
+% maintained on github (\url{https://github.com/polysyllabic/multicolrule}),
+% and you can file feature requests or bug reports there. Alternatively, you
+% can send an email to
+% \href{mailto://latex@polysyllabic.com}{latex@polysyllabic.com}. I welcome
+% contributions for additional styles, especially to provide more options when
+% running the package without \pkg{tikz}.
+%  
+% The line styles that work by repeating elements in a tiled pattern may have
+% significant gaps at the end of columns, particularly for larger patterns.
+% You can mitigate this problem slightly by tweaking the spaces above and
+% below a pattern, but the basic problem is a side-effect of the way these
+% patterns are implemented (with \cs{cleaders}), which means that only an
+% integer number of copies can be produced. Lines drawn with \pkg{tikz} do not
+% have this problem.
+% 
+% I have also noticed occasional instances, most noticeably when a
+% \env{multicols} environment starts near the bottom of a page and the columns
+% continue to the next one, where the rules are either somewhat shorter than
+% they should be or shifted upward from where they belong. In the limited
+% testing I have done, this appears to be a consequence of how \pkg{multicol}
+% works, as the default rules show the same behavior. I may try to nail down
+% this issue in future version, but as it's an edge case that disappears when
+% you add page breaks or rewrite the text to alter how the columns are filled,
+% it hasn't seemed worth 
+% 
+% This package works by patching the output routines of either \pkg{multicol}
+% or the \LaTeX{} kernel, depending on the mode of operation. It therefore will
+% have no effect if you use a class or package that outputs column text via
+% alternate mechanisms. This includes \pkg{parcolumns}, and probably other
+% classes and packages designed to typeset parallel-column text as well, although
+% I have not done a survey to determine whether this is the case. If you would
+% like support for one of these, please send me an email or file a feature
+% request on github and I'll see what I can do.
+% 
+% \mcrule{} is written using expl3 syntax, and so requires a less-than-ancient
+% installation of \LaTeX. It uses the packages \pkg{l3keys2e}, \pkg{xparse},
+% \pkg{xpatch}, and \pkg{xcolor}, and depending on the mode of operation may
+% also require \pkg{multicol} and \pkg{tikz}. If you have an up-to-date
+% distribution, these requirements should cause no issues.
+% \end{multicols}

+% \SetMCRule{width=ultra-thick,line-style=dotted}
+% The\stydsc{\texttt{line-style=dotted, width=ultra-thick}} \mcrule{}
+% package is copyright 2018 by Karl Hagen. It may be distributed and/or modified
+% under the conditions of the \LaTeX{} Project Public License, either version 1.3
+% of this license or (at your option) any later version. The latest version of
+% this license is in \url{http://www.latex-project.org/lppl.txt} and version 1.3
+% or later is part of all distributions of \LaTeX{} version 2005/12/01 or later.
+%  
+% This work has the LPPL maintenance status `maintained.' The Current
+% Maintainer of this work is Karl Hagen.
+% \end{multicols}
+%
+%\begin{multicols}{2}[\section{Package Options}]
+% \SetMCRule{line-style=dash-dot}
+%
+% \subsection{Default Operation}
+% If\stydsc{line-style=dash-dot} you load \mcrule{} with its default settings,
+% it will enable \pkg{multicol} support, and that package will be loaded if it
+% hasn't been already. Note that if you need to pass any parameters to
+% \pkg{multicol}, such as |docolaction|, you should load \pkg{multicol} with
+% the appropriate settings \emph{before} you load \mcrule, as \LaTeX{} does not
+% support reloading packages with different parameters.
+% 
+% \subsection{Option `twocolumn'}
+% \DescribeOption{twocolumn}
+% The \mcrule{} package recognizes the option \opt{twocolumn},
+% either as a package option or as a global class option. If you pass this option
+% to your document class, you do not need to pass it a second time to the
+% package. It is only necessary to use the package option if you plan to have a
+% predominantly one-column document and use \cs{twocolumn} to switch
+% temporarily into two-column mode.
+% 
+% Because \pkg{multicol} does not work well with the ordinary two-column
+% mode, \mcrule{} is only designed to work with one or the other at a time. If
+% you try to use the \opt{twocolumn} option when
+% \pkg{multicol} has already been loaded, you will receive a warning, and
+% nothing is guaranteed. But the custom rules will at best only appear in the
+% conventional two-column mode and not within a \env{multicols} environment.
+% 
+% \subsection{Option `tikz'}
+% \DescribeOption{tikz}
+% You have access to a wider set of line styles if you also use the \pkg{tikz}
+% package. Some line styles are only available if \pkg{tikz} is enabled, and
+% others look better with it. The default behavior of \mcrule{} depends on the
+% status of the \pkg{tikz} package at the time \mcrule{} is loaded. If
+% \mcrule{} detects that \pkg{tikz} is already loaded, then tikz support will
+% be enabled by default. Otherwise, you need the \opt{tikz} to enable it. This
+% option also accepts explicit boolean values, so you can pass |tikz=false| if
+% you want to explicitly disable tikz support. If tikz support is not enabled
+% (or if it is explicitly disabled), the line styles marked \emph{tikz only}
+% in section \ref{sec:linestyles} will be unavailable and errors will result
+% if you try to use them.
+% \end{multicols}
+%
+% \begin{multicols}{2}[\section{The User Interface}]
+% \SetMCRule{width=2pt,line-style=circles}
+% \DescribeMacro{\SetMCRule}
+% The\stydsc{line-style=circles,\\width=2pt} \mcrule{} package has
+% just a single user command:
+%
+% \cs{SetMCRule} \marg{key-value}
+%
+% which takes one parameter containing a key-value list of all options you
+% want to set. You can issue this command in the preamble or the document body.
+% Changes to the rule settings are local to the current group. For example, if
+% you call \cs{SetMCRule} inside a \env{multicols} environment, the rule
+% settings will revert to their previous values once the environment ends. Also
+% note that any changes made with \cs{SetMCRule} when multiple columns are
+% active will appear starting on the same page as your current location when you
+% issue the command, and will extend the height of the full column box. It is not
+% possible to have a rule change styles in the middle of a page unless you close
+% out one \env{multicols} environment and begin another.
+%  
+% Table \ref{table:mcrulekeys} summarizes the keys available in \cs{SetMCRule}.
+% The functions of each is described in detail in the sections that follow.

+%  \SetMCRule{width=4pt,line-style=solid-circles}
+%  
+% You\stydsc{line-style=solid-circles,\\width=4pt} choose a style for the rule
+% with the \kvdesc{line-style} key. The default style is \kvdesc{solid}. In
+% addition to the predefined styles, there are also several ways to get

+% most line styles depends on the setting of \cs{columnseprule}, which is the
+% default \LaTeX{} length that controls the width of the column rule
+% (see section \ref{sec:width}). 
+%  
+% Table \ref{table:linestyles} summarizes the available line styles.
+% Most of the basic shapes used to form the patterns come in three versions,
+% which differ only in how closely the pattern is spaced: normal, dense, and
+% loose. These settings parallel those found in \pkg{tikz}, and those
+% line styles whose names are identical to the line patterns in \pkg{tikz}
+% (apart from the substitution of `-' for spaces) produce the same effect.

+% \begin{multicols}{2}[\subsubsection{Notes on the Styles}]
+% \SetMCRule{width=thin,line-style=solid} 
+% The\stydsc{line-style=solid} \kvdesc{solid}
+% line style is the default. In fact, if you make no calls to \cs{SetMCRule}
+% after loading \mcrule, the column divider will behave exactly as it does with
+% the ordinary \pkg{multicol} package. You can alter its width and color either
+% with the
+% \kvdesc{width} and \kvdesc{color} keys described in
+% sections \ref{sec:width} and \ref{sec:color}, respectively, or you can set the
+% width directly by changing the value of \cs{columnseprule} and renewing the
+% \cs{columnseprulecolor} macro. Like all line styles, the solid line can be
+% repeated as many times as you like (see section \ref{sec:repeats}).
+%  
+% The \kvdesc{dots} style and its variants are rendered with a period
+% (.) in the currently active font. This means that changing
+% \cs{columnseprule} will not change the size of these dots, although, as with
+% all rules, it will not appear at all if \cs{columnseprule} is set to 0pt.
+%
+% The \kvdesc{dotted} styles differ from \kvdesc{dots} in
+% that the former are squares with side lengths equal to \cs{columnseprule}.
+% This mirrors the behavior of the equivalently named dotted patterns in
+% \pkg{tikz}.

+% \subsubsection{Custom Patterns}\label{sec:custom}
+%
+% \begin{multicols}{2}[\noindent\texttt{custom-tile=} \marg{pattern} \marg{space above}
+%   \marg{space below}]
+% \SetMCRule{custom-tile={\SparkleBold}{16pt}{16pt}}
+%
+% There\stydsc{custom-tile= \{\textbackslash SparkleBold\} \{16pt\}\{16pt\}}
+% are three options to create custom rules with \mcrule. The first is the
+% \kvdesc{custom-tile} key. This creates a rule consisting of vertically
+% stacked boxes of arbitrary content---the tile---running the height of the
+% column separator. The \kvdesc{custom-tile} key takes three parameters,
+% which must all be enclosed brackets and may not be omitted. The first
+% should contain the tokens you want to appear as the content of the tile.
+% The second is a dimension specifying the leading vertical space to apply
+% above each copy of the tile. The third is a dimension specifying the
+% trailing vertical space to insert below each copy of the tile.
+%
+% The rule in this section uses the \cs{SparkleBold} symbol from
+% \pkg{bbding}. Notice that when you use the \kvdesc{custom-tile} parameter,
+% you do \emph{not} specify a separate \kvdesc{line-style}.
+% \end{multicols}
+%
+% \begin{multicols}{2}[\noindent\texttt{custom-pattern=} \marg{pattern} \marg{shift
+%    down} \marg{shift up}]
+% \SetMCRule{custom-pattern={\HandRight}{0pt}{0pt}} 
+%
+% The\stydsc{custom-pattern= \{\textbackslash HandRight\} \{0pt\}\{0pt\}}
+% second custom option is with the \kvdesc{custom-pattern} key. The syntax
+% is identical to that for \kvdesc{custom-tile}, but the content you specify
+% will appear once per page or column pair (if the columns occupy less than a
+% full page). This content will be vertically centered if the second and third
+% parameters are both 0pt. You can shift the content down by increasing the
+% second parameter, and up by increasing the third. The rule in this section
+% uses the \cs{HandRight} symbol from \pkg{bbding}.
+% \end{multicols}
+%
+% \begin{multicols}{2}[\noindent\texttt{custom-line=} \marg{draw command}]
+% \SetMCRule{width=1pt,custom-line={\draw[line width=\columnseprule] (TOP) to
+%   [ornament=88] (BOT);}}
+%
+% The\stydsc{custom-line=\{ \textbackslash draw[line width= \textbackslash
+%   columnseprule] (TOP) to [ornament=88] (BOT);\},\\width=1pt} third custom
+% pattern involves setting your own \pkg{tikz} drawing
+% function using the key \kvdesc{custom-line}. The rule in this section is
+% drawn with an ornament from \pkg{pgfornaments}. Obviously, this feature
+% requires \pkg{tikz} support. The value you provide to the
+% \kvdesc{custom-line} key should consist of a \pkg{tikz} command, such as
+% \cs{draw}, without the surrounding \env{tikzpicture} environment.
+% 
+% Before the drawing command is called, \mcrule{} will set up a
+% \env{tikzpicture} with both the x- and y-coordinates scaled to points, and
+% two nodes, named \texttt{(TOP)} and \texttt{(BOT)}, which are set to the
+% coordinates of the top and bottom of the rule. You can then specify your own
+% \cs{draw} function in whatever way you like. The rule separating these
+% columns was drawn with a decorative element from the \pkg{pgfornaments}
+% package.
+%
+% This function will use the color set in
+% \cs{columnseprulecolor} if you don't set it explicitly within the tikz
+% command, but you must provide everything else necessary to draw the line
+% correctly, including the line width. Note that this function should be
+% considered experimental. It works for single-line commands such as the one
+% shown in the example, but I haven't tested it with anything more elaborate. 
+% \end{multicols}
+%
+% \begin{multicols}{2}[\subsection{Colors}\label{sec:color}]
+% \SetMCRule{width=2pt,line-style=solid,color-model=cmy,color={0.7,0.5,0.3}}
+% You\stydsc{line-style=solid,\\width=2pt\\color-model=cmy,\\
+% color=\{0.7,0.5,0.3\}} can set colors for the rule through the
+% \kvdesc{color} and, optionally, the \kvdesc{color-model} keys. \mcrule{} loads the
+% \pkg{xcolor} package to manage colors, and the \kvdesc{color}
+% parameter accepts any name that \pkg{xcolor} recognizes, either natively or
+% as the result of any names you have defined with \cs{definecolor}
+% (see the \pkg{xcolor} documentation). Note that if you want to use color names that
+% are defined through the one of \pkg{xcolor}'s package options, you must load 
+% \pkg{xcolor} before both \mcrule{} and \pkg{tikz} with the relevant options.
+%  
+% To specify a color by a numeric specification, you use the
+% \kvdesc{color-model} parameter to specify any color model that
+% \pkg{xcolor} recognizes (rgb, cmy, etc), and \kvdesc{color} to
+% hold the color-specification list. Because that list is itself comma-separated,
+% you must enclose it in brackets.
+%  
+% The current color setting can always be found in
+% \cs{columnseprulecolor}. If you are running in twocolumn
+% mode without \pkg{multicol}, this command will be provided and colors will
+% work the same way they do with \pkg{multicol}. Note that setting the 
+% \kvdesc{color} key causes \cs{columnseprulecolor}
+% to be redefined within the current group only. If you directly redefine
+% \cs{columnseprulecolor}, the color of the custom rule will
+% reflect this setting. This way, the settings of any packages that might alter
+% the rule color will be respected.

+%
+% \begin{multicols}{2}[\subsection{Width}\label{sec:width}]
+% \SetMCRule{width=thick,line-style=dash-dot-dot}
+% You\stydsc{line-style=dash-dot-dot,\\width=thick} can set the width of the
+% rule with the \kvdesc{width} key. Legal values are any explicit dimension or
+% dimension expression, as well as with names that parallel those used by
+% \pkg{tikz}, except that spaces in the key names are replaced with hyphens.
+%  
+% The current width of the rule is kept in \cs{columnseprule}, just as in
+% vanilla \LaTeX, and if it is set separately, the custom rule's width will
+% reflect this change. Note that although some line styles do not depend 
+% directly on \cs{columnseprule} to calculate their actual width, the value
+% of \cs{columnseprule} must be greater than 0pt for any rule to appear. This
+% behavior is intentional and is in keeping with the way the default column
+% rules work.

+% \begin{multicols}{2}[\subsection{Repeated Rules}\label{sec:repeats}]
+% \SetMCRule{line-style=dash-dot-dot,triple=2pt}
+%  
+% You can\stydsc{line-style= dash-dot-dot, triple=2pt} draw multiple,
+% adjacent copies of any rule by setting the number of times to draw the rule
+% with the \kvdesc{repeat} key. The space between copies is controlled with the
+% \kvdesc{repeat-distance} key. Initially, this distance is set to
+% \cs{columnseprule}.
+%  
+% The keys \kvdesc{single}, \kvdesc{double}, and \kvdesc{triple} are shorthand
+% methods to set the number of repeats and the \kvdesc{repeat-distance} at the
+% same time. If use the key without a value \kvdesc{repeat-distance} is set to 
+% \cs{columnseprule}.
+%
+% There are no checks made to ensure that repeated rules will fit in the
+% available space between columns, so you should be careful using these
+% commands, especially with thicker rules.
