% \section{Introduction}
%
% This document provides the commented source
% for the LaTeX \Lpack{memoir} class, which is designed for typesetting
% general books such as novels, biographies, histories,
% and so on. It has all the functionality of the standard \Lpack{book}
% class and, as well as providing some extra functions, also provides
% a more friendly interface for the document designer. As it can encompass
% everything that the \Lpack{book} class provides it may also be used
% for technical writing.
%
% The default appearance of a document typeset with this class is
% the same as if it had been typeset with the \Lpack{book} class and
% it can be made to simulate the \Lpack{article} class..
% The class, though, includes extra facilities that make it easy to
% change the appearance of such things as the page headers and footers,
% the style of chapter and other sectional headings, and the style of
% captions. It also makes it easy to both change the style of the
% Table of Contents, List of Figures, etc., as well as creating new
% kinds of `List of\ldots'. New types of floats, if needed, can be
% created very simply. Epigraphs can be put into the document in a
% variety of styles.
%
% The class provides a variety of page, chapter and captioning
% styles that you can choose from if you don't want to create your own.
%
% Documents can be typeset in 9pt, 10pt, 11pt, 12pt, 14pt or 17pt font
% sizes, and if you have scaleable fonts available they can be set at any size.
% There is a reasonably intuitive means of setting the margins
% and placement of the text on a page. There is an option to put
% trim marks on the printed pages if the stock sheets need to be trimmed
% down to the final page size. For those whose publishers like a
% manuscript to look as though it was typewritten, there is an option
% to do this (double spacing, ragged right, no hyphenation,
% fixed width font). There is also an unsophisticated means of flagging any
% revisions to the text.
%
% As this is a new class, by default it does not support the old
% LaTeX v2.09
% font commands, namely the \cs{bf}, \cs{sl}, \cs{it} and \cs{sc} commands;
% it warns about using the \cs{em} command but does support it.
%
%
% I hope that apart from the font commands the class
% is compatible with
% `standard' LaTeX.
%
% Development of this class would never have been started without
% the wonderful work done by Leslie Lamport and others~\cite{CLASSES}
% from whom I have learned a great deal and borrowed much code.
%
% Sections~\ref{sec:docstrip} through~\ref{sec:ic} describe some
% administrative elements and code for general use later in the
% specification.
% The macros forming the class file are defined in sections~\ref{sec:opt}
% through~\ref{sec:init}.
%
% This manual is typeset according to the conventions of the
% \LaTeX{} \textsc{docstrip} utility which enables the automatic
% extraction of the \LaTeX{} macro source files~\cite{GOOSSENS94}.
%
%
% \section{A driver for this document} \label{sec:docstrip}

% \subsection{Checking the processor}
%
% Prior to 2008/07/22 the \Lpack{hyperref} package was modified in such a
% way as to produce warnings about versions of the \Lpack{ifpdf} and
% \Lpack{ifxetex} packages when \Lpack{hyperref} was used with versions
% v1.618033,
% v1.61803, or v1.618 mempatch v4.9 of the class.
% \Lpack{hyperref}'s author refused to
% make any changes to his package, insisting that emulating a package was
% `ugly hacking'. He did, though, provide an example code that could be
% added to memoir
% to use a package if it was available. I have used it for the emulations
% in this section. There will be no further changes to the class to accomodate
% any further changes to \Lpack{hyperref} --- it's easy for a package to
% determine what class is being used and make arrangements accordingly,
% especially as there are not all that many classes. There are hundreds
% of packages that might be used with a particular class and it would be
% senseless for a class to attempt to take account of everything that might
% be used with it.

% \subsection{Extending an existing macro}
%
%
% My usual technique for modifying the code of an existing
% macro was to use \cs{renewcommand}. However it slowly became apparent that
% many of such modifications merely consisted of adding some code at
% either the start or end of the existing definition. In June 2000 I
% posed a question
% on the \texttt{comp.text.tex} newsgroup about this, and
% Michael Downes\footnote{\texttt{epsmjd@ams.org}} and
% Heiko Oberdiek\footnote{\texttt{oberdiek@ruf.uni-freiburg.de}}
% were kind enough to respond.
% The responses arrived almost simultaneously, both
% supplying methods for adding code at the end of a macro defined to take
% one argument. Michael Downes' response included a remark about it probably
% being too much effort to formulate a general way of doing this.
% Heiko Oberdiek almost immediately replied with such a generalisation.
%
% The following code, which I have extracted from a package that I
% wrote but which I did not submit to CTAN, incorporates the work of both
% Michael and Heiko. I have added a bit. All errors are my responsibility.
% Michael went on the write the \Lpack{patchcmd} package which is
% a generalisation of the facilities below and so there was no need for
% my more restricted package.
% \changes{v0.33}{2001/08/31}{Replaced \cs{appendiarg} with \cs{addtodef}
% and friends}
%
% \begin{macro}{\wo@dmacro}
% Heiko Oberdiek suggested\footnote{Via email on 2000/07/12.} that
% \meta{macro} should be tested for being the name of a macro, rather than
% using the normal \LaTeX{} test against it being undefined. He supplied
% the code for performing the macro name test.
%
% \cs{wo@dmacro} is a helper for handling the string `macro:'.

% \begin{macro}{\addtodef}

% \begin{macro}{\wo@daddtodef}
% The command \cs{addtodef}\marg{macro}\marg{start-stuff}\marg{end-stuff}
% adds stuff at the start and/or end of an argumentless macro.
% Initially the code for appending was a reimplementation of the
% kernel \cs{g@addto@macro} command (from \file{ltclass.dtx}).
% Later, at Michael Downes' suggestion, I combined
% appending and prepending stuff into a single command.
% Actually, there is no real need to have both
% \cs{addtodef} and \cs{addtodef*} as the body of the command
% being amended has no argument,
% but both versions are provided for consistency.
%
% The kernel \cs{@star@or@long} and \cs{l@ngrel@x} commands
% (in \file{ltdefns.dtx}) are used to handle
% the potential \verb?*? after the command name.
% \begin{macrocode}
\def\addtodef{\@star@or@long\wo@daddtodef}
% \end{macrocode}
% The \cs{@star@or@long} command dealt with a possible \verb?*? and now

%
% \subsection{Setting Paper Sizes}
%
% The variables \cs{paperheight} and \cs{paperwidth} should reflect the
% physical paper size after trimming.
%
% Option \Lopt{letterpaper} will be the default.
%
% \begin{macro}{\stockheight}
% \begin{macro}{\stockwidth}
% \begin{macro}{\trimtop}
% \begin{macro}{\trimedge}
% The lengths \cs{stockheight} and \cs{stockwidth} should be the height and
% width of the stock sheet before trimming. For example, this is the
% physical size
% of a single sheet that might be laser-printed. The lengths \cs{trimtop}
% and \cs{trimedge} are the amount that will be trimmed off the top and fore
% edge of the physical sheet.
% For desk printer output the size of the trimmed sheet is often the
% same as the physical sheet. In other words the \cs{paper...} and \cs{stock...}
% sizes are the same and the trims are zero. This class assumes that this
% is the normal case.
% \begin{macrocode}
\newlength{\stockheight}

% \subsection{Choosing the type size}
%
% The type size options are handled by defining \cs{@ptsize} to contain
% the last digit of the size in question and branching on \cs{ifcase}
% statements. This is done for historical reasons to stay compatible
% with other packages that use the \cs{@ptsize} variable to select
% special actions. It makes the declarations of size options less
% than 10pt or more than 20pt difficult. In this class \texttt{9} is used
% for the \Lopt{9pt} option, assuming that the class will never define a
% \Lopt{19pt} option. For larger options the full complement of digits
% are used.
%
% In any event, \cs{@memptsize} holds the complete size.
%
% Option \Lopt{10pt} will be the default.
% \changes{v1.2}{2002/07/07}{Added 17pt option}

%
% In this section we deal with most of the aspects that are related
% to font sizes, and spacing that is related to the size of the body font.
%
% \subsection{Fonts}
%
% \LaTeX\ offers the user commands to change the size of the font,
% relative to the `main' size. Each relative size changing command
% \cs{size} executes the command
% \verb?\@setfontsize\size? \meta{font-size} \meta{baselineskip} where:
%
% \begin{description}
% \item[\meta{font-size}] The absolute size of the font to use from
% now on.
%
% \item[\meta{baselineskip}] The normal value of \cs{baselineskip}
% for the size of the font selected. (The actual value will be
% \cs{baselinestretch} * \meta{baselineskip}.)
% \end{description}
%
% A number of commands, defined in the \LaTeX\ kernel, shorten the
% following definitions and are used throughout. They are listed in
% the first part of Table~\ref{tab:sh}. Those in the second part are introduced
% by the class.
%
% \begin{table}
% \centering
% \caption{Shorthand font point size commands}\label{tab:sh}

%
% \begin{macro}{\normalsize}
% \begin{macro}{\@normalsize}
%
% The user level command for the main size is \cs{normalsize}.
% Internally \LaTeX\ uses \cs{@normalsize} when it refers to the
% main size. \cs{@normalsize} will be defined to work like
% \cs{normalsize} if the latter is redefined from its default
% definition (that just issues an error message). Otherwise, in the standard
% classes \cs{@normalsize} simply selects a 10pt/12pt size, but here
% it selects among the wider range.
%
% The \cs{normalsize} macro also sets new values for\\
% \cs{abovedisplayskip}, \cs{abovedisplayshortskip} and
% \cs{belowdisplayshortskip}.
%
% For the larger sizes I have set \cs{abovedisplayskip} to the font size
% and \cs{belowdisplayshortskip} to 0.5\cs{onelineskip}.

% \section{Page Styles}
%
% The page style \pstyle{foo} is defined by defining the command
% \cs{ps@foo}. This command should make only local definitions.
% There should be no stray spaces in the definition, since they
% could lead to mysterious extra spaces in the output.
%
% \begin{macro}{\@evenhead}
% \begin{macro}{\@oddhead}
% \begin{macro}{\@evenfoot}
% \begin{macro}{\@oddfoot}
% The \cs{ps@...} command defines the macros \cs{@oddhead},
% \cs{@oddfoot}, \cs{@evenhead}, and \cs{@evenfoot} to define the running
% heads and feet---e.g., \cs{@oddhead} is the macro to produce the
% contents of the heading box for odd-numbered pages. It is called
% inside an \cs{hbox} of width \cs{textwidth}.
% \end{macro}
% \end{macro}
% \end{macro}
% \end{macro}
%
% \subsection{Marking conventions}
%
% To make headings determined by the sectioning commands, the page
% style defines the commands \cs{chaptermark}, \cs{sectionmark},
% \ldots,\\
% where \cs{chaptermark}\marg{TEXT} is called by
% \cs{chapter} to set a mark, and so on.
%
% The \cs{...mark} commands and the \cs{...head} macros are defined
% with the help of the following macros. (All the \cs{...mark}
% commands should be initialized to no-ops.)
%
% \LaTeX{} extends \TeX's \cs{mark} facility by producing two kinds
% of marks, a `left' and a `right' mark, using the following
% commands:
% \begin{flushleft}
% \cs{markboth}\marg{LEFT}\marg{RIGHT}: Adds both marks.
%
% \cs{markright}\marg{RIGHT}: Adds a `right' mark.
%
% \cs{leftmark}: Used in the \cs{@oddhead}, \cs{@oddfoot}, \cs{@evenhead}
% or \cs{@evenfoot} macros, it gets the current `left'
% mark. \cs{leftmark} works like \TeX's \cs{botmark}
% command.
%
% \cs{rightmark}: Used in the \cs{@oddhead}, \cs{@oddfoot}, \cs{@evenhead}
% or \cs{@evenfoot} macros, it gets the current
% `right' mark. \cs{rightmark} works like \TeX's
% \cs{firstmark} command.
% \end{flushleft}
%
% The marking commands work reasonably well for right marks
% `numbered within' left marks--e.g., the left mark is changed by a
% \cs{chapter} command and the right mark is changed by a \cs{section}
% command. However, it does produce somewhat anomalous results if
% two \cs{markboth}'s occur on the same page.
%
%
% Commands like \cs{tableofcontents} that should set the marks in some
% page styles use a \cs{@mkboth} command, which is \cs{let} by the
% pagestyle command (\cs{ps@...}) to \cs{markboth} for setting the
% heading or to \cs{@gobbletwo} to do nothing.
%
%
%
% \subsection{Defining the page styles}
%
% This class provides a set of commands for the user to define new
% pagestyles. Essentially defining a pagestyle consists of defining the
% macros \cs{@evenhead}, \cs{@oddhead}, \cs{@evenfoot}, and \cs{@oddfoot}.
% For this class, each header and footer is treated as three parts: a left,
% center, and right part. In this case, defining a pagestyle consists of
% specifying these 12 portions of the running headers and footers. The
% width of the headers/footers may also be specified, rules may be drawn
% below the headers and/or above the footers, and the complete header and/or
% footer may be offset with respect to the textblock when the width is not
% the same as the textwidth.
%
% In the following \meta{style} is the name of a pagestyle being defined
% (e.g., \verb?ruled?).
%
% \begin{macro}{\makeevenhead}
% The command
% \cs{makeevenhead}\marg{style}\marg{left}\marg{center}\marg{right}
% specifies that the left, center and right portions of the even header for
% pagestyle \meta{style} are defined as the other three arguments, respectiveley.
% Internally it defines the commands \cs{styleeheadl}, \cs{styleeheadc} and
% \cs{styleeheadr} to be \meta{left}, \meta{center} and \meta{right} respectively.

% \section{Titles}
%
% For books the title is usually designed specifically for the particular

% After some thought I decided to add in the code from the
% \Lpack{titling} package~\cite{TITLING}. However, in this case life
% is a bit simpler as there is no pre-existing class code.

% \section{Parts, chapters and other divisions}
%
% \subsection{Building blocks} The definitions in this part of a
% class file usually make use of two internal macros, \cs{@startsection} and
% \cs{secdef}. To understand
% what is going on here, we describe their syntax.
%
% \DescribeMacro{\@startsection}
% The macro \cs{@startsection} has 6 required arguments, optionally
% followed by a $*$, an optional argument and a required argument:
%
% \cs{@startsection}\meta{name}\meta{level}\meta{indent}^^A
% \meta{beforeskip}\meta{afterskip}\meta{style}
% optional * %\\
% \null\hphantom{\bslash @startsection}^^A
% \oarg{altheading}\meta{heading}
%
% It is a generic command to start a section, the arguments have
% the following meaning:
%
% \begin{description}
% \item[\meta{name}] The name of the user level command, e.g.,
% `section'.
% \item[\meta{level}] A number, denoting the depth of the section
% --- e.g., chapter = 0, section = 1, etc. A section number
% will be printed if and only if \meta{level} $<=$ the value
% of the \Lcount{secnumdepth} counter.
% \item[\meta{indent}] The indentation of the heading from the left
% margin
% \item[\meta{beforeskip}] The absolute value of this argument
% gives the skip to leave above the heading. If it is
% negative, then the paragraph indent of the text following
% the heading is suppressed.
% \item[\meta{afterskip}] If positive, this gives the skip to leave
% below the heading, else it gives the skip to leave to the
% right of a run-in heading.
% \item[\meta{style}] Commands to set the style of the heading.
% \item[$*$] When this is missing the heading is numbered and the
% corresponding counter is incremented.
% \item[\meta{altheading}] Gives an alternative heading to use in
% the table of contents and in the running heads. This should
% be present when the $*$ form is used.
% \item[\meta{heading}] The heading of the new section.
% \end{description}
% A sectioning command is normally defined to \cs{@startsection} and
% its first six arguments.
%
% \DescribeMacro{\secdef}
% The macro \cs{secdef} can be used when a sectioning command is
% defined without using \cs{@startsection}. It has two arguments:
%
% \cs{secdef}\meta{unstarcmds}\meta{starcmds}
%
% \begin{description}
% \item[\meta{unstarcmds}] Used for the normal form of a
% sectioning command.
% \item[\meta{starcmds}] Used for the $*$-form of a
% sectioning command.
% \end{description}
%
% You can use \cs{secdef} as follows:
% \begin{verbatim}
% \def\chapter { ... \secdef \CMDA \CMDB }
% \def\CMDA [#1]#2{ ... } % Command to define
% % \chapter[...]{...}
% \def\CMDB #1{ ... } % Command to define
% % \chapter*{...}
% \end{verbatim}
%
% \DescribeMacro{\@hangfrom}
% Internally the \cs{@startsection} macro uses \verb?\@hangfrom{NUM}?, where
% \verb?NUM? is the sectional number, to produce a hanging paragraph. That is,
% the second and later lines of a multiline title are indented from the
% left margin by the width of the number.
% The definition of \cs{@hangfrom}, from \file{ltsect.dtx}, is:
% \begin{verbatim}
% \def\@hangfrom#1{\setbox\@tempboxa\hbox{{#1}}%
% \hangindent \wd\@tempboxa\noindent\box\@tempboxa}
% \end{verbatim}
%
% To get a normal paragraphed title you can do: \\
% \verb?\renewcommand{\@hangfrom}[1]{#1}? \\
% or as a block paragraph: \\
% \verb?\renewcommand{\@hangfrom}[1]{\noindent #1}}? \\
%
% \DescribeMacro{\@seccntformat}
% The \cs{@startsection} macro also uses \verb?\@seccntformat{NUM}? to format
% the section number, including the space after it. Its definition,
% from \file{ltsect.dtx}, is
% \begin{verbatim}
% \def\@seccntformat#1{\csname the#1\endcsname\quad}
% \end{verbatim}
% This is the command to change if you need different number formatting. For
% example the combination
% \begin{verbatim}
% \renewcommand{\@seccntformat}[1]{\llap{\csname the#1\endcsname\quad}}
% \renewcommand{\@hangfrom}[1]{\noindent #1}
% \end{verbatim}
% will hang the section numbers in the margin.

% The following is taken directly from David Carlisle's
% \Lpack{enumerate} package.
%
% START OF DAVID CARLISLE'S CODE AND COMMENTARY
%
% This package gives the enumerate environment an optional argument
% which determines the style in which the counter is printed.
%
% An occurence of one of the tokens \verb?A a I i? or \verb?1? produces the value
% of the counter printed with (respectively) \verb?\Alph \alph \Roman \roman?
% or \cs{arabic}.
%
% These letters may be surrounded by any strings involving any other
% \TeX\ expressions, however the tokens \verb?A a I i 1? must be inside a
% \verb?{ }? group if they are not to be taken as special.
%
%
% \begin{macro}{\@enlab}
% Internal token register used to build up the label command from the
% optional argument.
% \begin{macrocode}
\newtoks\@enLab
% \end{macrocode}
% \end{macro}
%
% \begin{macro}{\@enQmark}
% This just expands to a `?'. \cs{ref} will produce this, if no counter
% is printed.
% \begin{macrocode}
\def\@enQmark{?}
% \end{macrocode}
% \end{macro}
%
% The next four macros build up the command that will print the item
% label. They each gobble one token or group from the optional argument,
% and add corresponding tokens to the register \cs{@enLab}. They each end
% with a call to \cs{@enloop}, which starts the processing of the next
% token.
% \begin{macro}{\@enLabel}
% Add the counter to the label. \verb?#2? will be one of the `special'
% tokens \verb?A a I i 1?, and is thrown away. \verb?#1? will be a command
% like \cs{Roman}.

% \end{macro}
%
% \begin{macro}{\@enSpace}
% \begin{macro}{\@enSp@ce}

% as you can not do this with a macro argument.

% Hook for possible extensions.
% Some packages may want to extend the number of special characters
% that are associated with counter representations. This feature
% was requested to enable Russian alphabetic counting, but here
% I give an example of a footnote symbol counter, triggered by \verb?*?.
%
% To enable a new counter type based on a letter, you just need
% to add a new \cs{ifx} clause by analogy with the code above.
% So for example to make \verb?*? trigger footnote symbol counting.
% a package should do the following.
%
% Initialise the hook, in case the package is loaded before
% \textsf{enumerate}.
%\begin{verbatim}
% \providecommand\@enhook{}
%\end{verbatim}
%
% Add to the hook a new \cs{ifx} clause that associates \verb?*? with the
% \cs{fnsymbol} counter command.
%\begin{verbatim}
% \g@addto@macro\@enhook{%
% \ifx *\@entemp
% \def\@memtempa{\@enLabel\fnsymbol}%
% \fi}
%\end{verbatim}
% This code sequence should work whether it is loaded before or after
% this enumerate package. Any number of new counter types may be added
% in this way.
%
% At this point we just need initialise the hook, taking care not
% to over write any definitions another package may already have added.
% (PRW: as this is now in a class, it can be defined instead of

% \subsubsection{The construction of the preamble}
%
% \begin{PW}
% PW: The original \Lpack{array} package has redundant code (caused by a quick
% mashing of an early \Lpack{array} and the \Lpack{newarray} packages). I
% have tried to remove the redundancies and overlaps.
% \end{PW}
%
% It is obvious that those environments will consist mainly of an
% \cs{halign}, because \TeX\ typesets tables using this primitive.
% That is why we will now take a look at the algorithm which determines
% a preamble for a \cs{halign} starting with a given user preamble
% using the options mentioned above.
%
% The most interesting macros of this implementation are without doubt
% those which are responsible for the construction of the preamble for
% the \cs{halign}. The underlying algorithm was developed by
% \textsc{Lamport} (resp.\ \textsc{Knuth}, see texhax V87\#??), and it
% has been extended and improved.
%
% The user preamble will be read \textsf{token} by \textsf{token}. A
% \textsf{token} is a single character like \texttt{c} or a block
% enclosed in \verb?{...}?. For example the preamble of
% \verb?\begin{tabular}?\linebreak[0]\verb?{lc||c@{\hspace{1cm}}}? consists of
% the \textsf{token} \texttt{l}, \texttt{c}, \verb?|?, \verb?|?,
% \texttt{@} and \verb?\hspace{1cm}?.
%
% The currently used \textsf{token} and the one, used before, are needed
% to decide on how the construction of the preamble has to be
% continued.
% In the example mentioned above the \texttt{l} causes the preamble
% to begin with \verb?\hskip\tabcolsep?. Furthermore
% \verb?# \hfil? would be appended to define a flush left column.
% The next \textsf{token} is a \texttt{c}. Because it was preceded by an
% \texttt{l} it generates a new column. This is done with
% \verb?\hskip \tabcolsep & \hskip \tabcolsep?. The column which is to
% be centered will be appended with \verb?\hfil # \hfil?.
% The \textsf{token} \verb?|? would then add a space of
% \verb?\hskip \tabcolsep?
% and a vertical line because the last
% \textsf{tokens} was a \texttt{c}.
% The following \textsf{token} \verb?|? would only add a space
% \verb?\hskip \doublerulesep? because it was preceded by the
% \textsf{token} \verb?|?. We will not discuss our example further but
% rather take a look at the general case of constructing preambles.
%
% The example shows that the desired preamble for the
% \cs{halign} can be constructed as soon as the action of all
% combinations
% of the preamble \textsf{tokens} are specified. There are 18 such
% \textsf{tokens}
% so we have $19 \cdot 18 = 342$ combinations if we count the
% beginning of
% the preamble as a special \textsf{token}. Fortunately, there are many
% combinations which generate the same spaces, so we can define
% \textsf{token} classes. We will identify a
% \textsf{token} within a class with a number, so we can insert the
% formatting (for example of a column).
% Table~\ref{tab:Klassen} lists all \textsf{token} classes and
% their corresponding numbers.

% \begin{macro}{\@chclass}
% \begin{macro}{\@chnum}
% \begin{macro}{\@lastchclass}
% The class and the number of the current \textsf{token} are saved in
% the
% \textsf{count} registers \cs{@chclass}
% and \cs{@chnum}, while the class of the previous
% \textsf{token} is stored in the
% \textsf{count} register \cs{lastchclass}.
% All of the mentioned registers are already allocated in
% \texttt{latex.tex},
% which is the reason why the following three lines of code are
% commented out.
% Later throughout the text I will not mention it again explicitely
% whenever I use a \verb?%? sign. These parts are already defined in

%
%
% \begin{macro}{\@addtopreamble}
% We will save the already constructed preamble for
% the \cs{halign}
% in the global macro \cs{@preamble}. This will then be
% enlarged with
% the command \cs{@addtopreamble}.
% \begin{macrocode}
\def\@addtopreamble#1{\xdef\@preamble{\@preamble #1}}
% \end{macrocode}
% \end{macro}
%
%
% \begin{macro}{\@testpach}
% With the help of \cs{@lastchclass} we can now define a macro
% which determines the class and the number of a given preamble
% \textsf{token}
% and assigns them to the registers
% \cs{@chclass} and \cs{@chnum}.
% \begin{macrocode}
\def\@testpach{\@chclass
% \end{macrocode}
% First we deal with the cases in which the \textsf{token}
% (\verb?#1?) is the argument of \texttt{!}, \texttt{@}, \texttt{<} or
% \texttt{>}. We can see this from the value of \cs{@lastchclass}:
% \begin{macrocode}
\ifnum \@lastchclass=6 \@ne \@chnum \@ne \else
\ifnum \@lastchclass=7 5 \else
\ifnum \@lastchclass=8 \tw@ \else
\ifnum \@lastchclass=9 \thr@@
% \end{macrocode}
% Otherwise we will assume that the \textsf{token} belongs to the
% class 0
% and assign the corresponding number to \cs{@chnum} if our
% assumption is correct.
% \begin{macrocode}
\else \z@
% \end{macrocode}
% If the last \textsf{token} was a \texttt{p}, \texttt{m} or a
% \texttt{b}, \cs{@chnum} already has the right value. This is the
% reason for the somewhat curious choice of the \textsf{token}
% numbers in class 10.
% \begin{macrocode}
\ifnum \@lastchclass = 10 \else
% \end{macrocode}
% Otherwise we will check if \cs{@nextchar} is either a \texttt{c},
% \texttt{l} or an \texttt{r}. Some applications change the
% catcodes of certain characters like ``\texttt{@}'' in
% \texttt{amstex.sty}. As a result the tests below would fail since
% they assume non-active character tokens. Therefore we evaluate
% \cs{@nextchar} once thereby turning the first token of its
% replacement text into a char. At this point here this should have
% been the only char present in \cs{@nextchar} which put into via a
% \cs{def}.
% \begin{macrocode}
\edef\@nextchar{\expandafter\string\@nextchar}%
\@chnum
\if \@nextchar c\z@ \else
\if \@nextchar l\@ne \else
\if \@nextchar r\tw@ \else
% \end{macrocode}
% If it is a different \textsf{token}, we know that the class was
% not 0. We assign the value 0 to \cs{@chnum} because this value
% is needed for the \verb?|?--\textsf{token}. Now we must check
% the remaining classes. Note that the value of \cs{@chnum} is
% insignificant here for most classes.
% \begin{macrocode}
\z@ \@chclass
\if\@nextchar |\@ne \else
\if \@nextchar !6 \else
\if \@nextchar @7 \else
\if \@nextchar <8 \else
\if \@nextchar >9 \else
% \end{macrocode}
% The remaining permitted \textsf{tokens} are \texttt{p},
% \texttt{m} and \texttt{b} (class 10).
% \begin{macrocode}
10
\@chnum
\if \@nextchar m\thr@@\else
\if \@nextchar p4 \else
\if \@nextchar b5 \else
% \end{macrocode}
% Now the only remaining possibility is a forbidden \textsf{token},
% so we choose class 0 and number 0 and give an error message.
% Then we finish the macro by closing all \cs{if}'s.
% \begin{macrocode}
\z@ \@chclass \z@ \@preamerr \z@ \fi \fi \fi \fi
\fi \fi \fi \fi \fi \fi \fi \fi \fi \fi \fi \fi}
% \end{macrocode}
% \end{macro}
%
% The preamble will be enlarged with the help of \cs{xdef}, but the
% arguments of \texttt{>}, \texttt{<},~\texttt{!}\ and \texttt{@} are
% not supposed to be expanded during the construction (we want an
% implementation that doesn't need a \cs{protect}). So we have to find a
% way to inhibit the expansion of those arguments.
%
% We will solve this problem with \textsf{token} registers. We need
% one register for every \texttt{!}\ and \texttt{@}, while we need two
% for every \texttt{c}, \texttt{l}, \texttt{r}, \texttt{m}, \texttt{p}
% or \texttt{b}. This limits the number of columns of a table because
% there are only 256 \textsf{token} registers. But then, who needs
% tables with more than 100 columns?
%
% So how do we proceed? Let us assume that we had \verb?!{foo}? in the
% user preamble and say we saved \texttt{foo} in
% \textsf{token} register 5. Then we call
% \verb?\@addtopreamble{\the@toks5}? where
% \cs{the@toks} is defined in a way that it does not expand
% (for example it could be equivalent to \cs{relax}). Every
% following call
% of \cs{@addtopreamble} leaves \cs{the@toks5} unchanged in
% \cs{@preamble}. If the construction of the preamble is completed
% we change the definition of \cs{the@toks} to
% \verb?\the\toks? and expand \cs{@preamble} for the last time.
% During this process all parts of the form
% \cs{the@toks}\meta{Number}
% will be substituted by the contents of the respective \textsf{token}
% registers.
%
% As we can see from this informal discussion the construction of the
% preamble has to take place within a group, so that the
% \textsf{token} registers we use will be freed later on. For that
% reason we keep all assignments to \cs{@preamble} global; therefore the
% replacement text of this macro will remain the same after we leave
% the group.
%
% \begin{macro}{\count@}
% We further need a \textsf{count} register to remember which
% \textsf{token} register is to be used next. This will be
% initialized with -1 if we want to begin with the \textsf{token}
% register 0. We use the \PlainTeX\ scratch register \cs{count@}
% because everything takes place locally. All we have to do is
% insert \cs{the@toks} \cs{the} \cs{count@} into the preamble.
% \cs{the@toks} will remain unchanged and \verb?\the\count@? expands into
% the saved number.
% \end{macro}
%
% \begin{macro}{\prepnext@tok}
% The macro \cs{prepnext@tok} is in charge of preparing the next
% \textsf{token} register. For that purpose we increase
% \cs{count@} by 1:
% \begin{macrocode}
\def\prepnext@tok{\advance \count@ \@ne
% \end{macrocode}
% Then we locally delete any contents the
% \textsf{token} register might have.
% \begin{macrocode}
\toks\count@{}}
% \end{macrocode}
% \end{macro}
%
% \begin{macro}{\save@decl}
% During the construction of the preamble the current
% \textsf{token} is always saved in the macro \cs{@nextchar} (see the
% definition of \cs{@mkpream}). The macro
% \cs{save@decl} saves it into the next free \textsf{token} register,
% i.e.\ in \verb?\toks\count@?.
% We do not assume that the token register is free, we add the new
% declarations to the front of the register. This is to allow user
% preambles of the form, \verb?>{foo}>{bar}..?. Users are not encouraged to
% enter such expressions directly, but they may result from the
% rewriting of \cs{newcolumntype}'s.
% \begin{macrocode}
\def\save@decl{\toks \count@ = \expandafter\expandafter\expandafter
{\expandafter\@nextchar\the\toks\count@}}
% \end{macrocode}
% \end{macro}
%
% How does the situation look like, if we want to add another column
% to the preamble, i.e.\ if we have found a \texttt{c}, \texttt{l},
% \texttt{r}, \texttt{p}, \texttt{m} or \texttt{b} in the user
% preamble? In this case we have the problem of the \textsf{token}
% register from \verb?>{..}? and \verb?<{..}? having to be inserted at this
% moment because formating instructions like \cs{hfil} have to be set
% around them. On the other hand it is not known yet, if any \verb?<{..}?
% instruction will appear in the user preamble at all.
%
% We solve this problem by adding two \textsf{token} registers at a
% time. This explains, why we have freed the \textsf{token} registers
% in \cs{prepnext@tok}.
%
% \begin{macro}{\insert@column}
% \begin{macro}{\@sharp}
% We now define the macro \cs{insert@column} which will do
% this work for us.
% \begin{macrocode}
\def\insert@column{%
% \end{macrocode}
% Here, we assume that the \textsf{count} register
% \cs{@tempcnta} has saved the value \verb?\count@?-1.
% \begin{macrocode}
\the@toks \the \@tempcnta
% \end{macrocode}
% Next follows the \verb?#? sign which specifies the place
% where the text of the column shall be inserted. To avoid
% errors during the expansions in
% \cs{@addtopreamble} we hide this sign in the command
% \cs{@sharp} which is temporarily occupied with
% \cs{relax} during the build-up of the preamble.
% To remove unwanted spaces before and after the column text, we set
% an \cs{ignorespaces} in front and a \cs{unskip} afterwards.
% \begin{macrocode}
\ignorespaces \@sharp \unskip
% \end{macrocode}
% Then the second \textsf{token} register follows whose number should
% be saved in \cs{count@}.
% We make sure that there will be no further expansion after reading
% the number, by finishing with \cs{relax}. The case above is not
% critical since it is ended by \cs{ignorespaces}.
% \begin{macrocode}
\the@toks \the \count@ \relax}
% \end{macrocode}

% \begin{macro}{\m@mold@addamp}
% \begin{macro}{\m@m@addamp}
% \begin{macro}{\@addamp}
%
% In the preamble a \verb?&? has to be inserted between any two columns;
% before the first column there should not be a \verb?&?. As the user

%
% \begin{PW}
% PW: Later on, for horizontal lines in `continuous' tabulars,

% (a counter used in tabbing) to store the number of columns.
%
% \cs{m@mold@addamp} stores the kernel's definition of \cs{@addamp}, and

% \begin{macro}{\@acol}
% \begin{macro}{\@acolampacol}
% \begin{macro}{\col@sep}
% We will now define some abbreviations for the extensions,
% appearing most often in the preamble build-up.
% Here \cs{col@sep} is a \textsf{dimen} register which is set
% equivalent to \cs{arraycolsep} in an \textsf{array}--environment,
% otherwise it is set equivalent to \cs{tabcolsep}.
% \begin{macrocode}
\newdimen\col@sep
\def\@acol{\@addtopreamble{\hskip\col@sep}}

% \end{macro}
%
% \begin{macro}{\@mkpream}
% \begin{macro}{\the@toks}
% Now we can define the macro which builds up the preamble for the
% \cs{halign}.
% First we initialize \cs{@preamble}, \cs{@lastchclass}
% and the boolean variable \cs{if@firstamp}.
% \begin{macrocode}
\def\@mkpream#1{\gdef\@preamble{}\@lastchclass 4 \@firstamptrue
% \end{macrocode}
% During the build-up of the preamble we cannot directly use the
% \verb?#? sign; this would lead to an error message in the next
% \cs{@addtopreamble} call.
% Instead, we use the command \cs{@sharp} at places where later
% a \verb?#? will be.
% This command is at first given the meaning \cs{relax};
% therefore it will not be expanded when the preamble
% is extended.
% In the macro \cs{@array}, shortly before the \cs{halign}
% is carried out, \cs{@sharp} is given its final meaning.
%
% In a similar way,
% we deal with the commands \cs{@startpbox} and
% \cs{@endpbox}, although the reason is different here: these
% macros expand in many \textsf{tokens} which would delay the
% build-up of the preamble.
% \begin{macrocode}
\let\@sharp\relax \let\@startpbox\relax \let\@endpbox\relax
% \end{macrocode}
% Now we remove possible \verb?*?-forms and user-defined column
% specifiers in the user preamble by repeatedly executing the list
% \cs{NC@list} until the re-writes have no more effect. The
% expanded preamble will then be in the token register
% \cs{@temptokena}. Actually we need to know at this point that
% this is not \cs{toks0}.
% \begin{macrocode}
\@temptokena{#1}\@tempswatrue
\@whilesw\if@tempswa\fi{\@tempswafalse\the\NC@list}%
% \end{macrocode}
% Afterwards we initialize all registers and macros, that we need
% for the build-up of the preamble.
% Since we want to start with the \textsf{token} register 0,
% \cs{count@} has to contain the value -1.
% \begin{macrocode}
\count@\m@ne
\let\the@toks\relax
% \end{macrocode}
% Then we call up \cs{prepnext@tok} in order to prepare the
% \textsf{token} register 0 for use.
% \begin{macrocode}
\prepnext@tok
% \end{macrocode}
% Having expanded all tokens defined using \cs{newcolumntype} (including
% \verb?*?), we evaluate the remaining tokens, which are saved in
% \cs{@temptokena}. We use the \LaTeX--macro \cs{@tfor} to inspect each
% token in turn.
% The strange appearing construction with \cs{expandafter} is
% based on the fact that we have to put the replacement text of
% \cs{@tempa} and not the macro \cs{@tempa} to this
% \LaTeX--macro.
% \begin{macrocode}
\expandafter \@tfor \expandafter \@nextchar
\expandafter :\expandafter =\the\@temptokena \do
% \end{macrocode}
% The body of this loop (the group after the \cs{do})
% is executed for one \textsf{token} at a time, whereas
% the current \textsf{token} is saved in \cs{@nextchar}.
% At first we evaluate the current \textsf{token} with the already
% defined macro \cs{@testpach}, i.e.\ we assign to
% \cs{@chclass} the character class and to \cs{@chnum}
% the character number of this \textsf{token}.
% \begin{macrocode}
{\@testpach
% \end{macrocode}
% Then we branch out depending on the value of \cs{@chclass} into
% different macros that extend the preamble respectively.
% \begin{macrocode}
\ifcase \@chclass \@classz \or \@classi \or \@classii
\or \save@decl \or \or \@classv \or \@classvi
\or \@classvii \or \@classviii
% \end{macrocode}
% Class 9 is equivalent to class 10.
% \begin{macrocode}
\or \@classx
\or \@classx \fi
% \end{macrocode}
% Two cases deserve our special attention: Since the current
% \textsf{token} cannot have the character class 4 (start) we
% have skipped this possibility. If the character class is 3,
% only the content of \cs{@nextchar} has to be saved into the current
% \textsf{token} register; therefore we call up \cs{save@decl}
% directly and save a macro name. After the preamble has been
% extended we assign the value of \cs{@chclass} to the counter
% \cs{@lastchclass} to assure that this information will be available
% during the next run of the loop.
% \begin{macrocode}
\@lastchclass\@chclass}%
% \end{macrocode}
% After the loop has been finished space must still be added to
% the created preamble, depending on the last \textsf{token}.
% Depending on the value of \cs{@lastchclass} we perform
% the necessary operations.
% \begin{macrocode}
\ifcase\@lastchclass
% \end{macrocode}
% If the last class equals 0 we add a
% \verb?\hskip \col@sep?.
% \begin{macrocode}
\@acol \or
% \end{macrocode}
% If it equals 1 we do not add any additional space so that the
% horizontal lines do not exceed the vertical ones.
% \begin{macrocode}

% \end{macrocode}
% Class 2 is treated like class 0 because a \verb?<{...}? can
% only directly follow after class 0.
% \begin{macrocode}
\@acol \or
% \end{macrocode}
% Most of the other possibilities can only appear if the user
% preamble was defective. Class 3 is not allowed since after a
% \verb?>{..}? there must always follow a \texttt{c}, \texttt{l},
% \texttt{r}, \texttt{p},\texttt{m} or \texttt{b}. We report an
% error and ignore the declaration given by \verb?{..}?.
% \begin{macrocode}
\@preamerr \thr@@ \or
% \end{macrocode}
% If \cs{@lastchclass} is 4 the user preamble has been empty.
% To continue, we insert a \verb?#? in the preamble.
% \begin{macrocode}
\@preamerr \tw@ \@addtopreamble\@sharp \or
% \end{macrocode}
% Class 5 is allowed again. In this case
% (the user preamble ends with \verb?@{..}?) we need not
% do anything.
% \begin{macrocode}
\or
% \end{macrocode}
% Any other case means that the arguments to \verb?@?, \texttt{!},
% \texttt{<}, \texttt{>}, \texttt{p}, \texttt{m} or \texttt{b} have
% been forgotten. So we report an error and ignore the last
% \textsf{token}.
% \begin{macrocode}
\else \@preamerr \@ne \fi
% \end{macrocode}
% Now that the build-up of the preamble is almost finished we can
% insert the \textsf{token} registers and therefore redefine

% later.

%
% The preamble is extended by the macros \cs{@classz} to
% \cs{@classx} which are called by \cs{@mkpream}
% depending on \cs{@lastchclass}
% (i.e. the character class of the last \textsf{token}).
% \begin{macro}{\@classx}
% First we define \cs{@classx} because of its important r\^ole.
% When it is called we find that the current
% \textsf{token} is \texttt{p}, \texttt{m} or \texttt{b}.
% That means that a new column has to start.
% \begin{macrocode}
\def\@classx{%
% \end{macrocode}
% Depending on the value of \cs{@lastchclass} different actions
% must take place:
% \begin{macrocode}
\ifcase \@lastchclass
% \end{macrocode}
% If the last character class was 0 we separate the columns by
% \verb?\hskip\col@sep? followed by \verb?&? and another
% \verb?\hskip\col@sep?.
% \begin{macrocode}
\@acolampacol \or
% \end{macrocode}
% If the last class was class 1 --- that means that a vertical
% line was
% drawn, --- before this line a \verb?\hskip\col@sep? was inserted.
% Therefore there has to be only a \verb?&? followed by
% \verb?\hskip\col@sep?. But this \verb?&? may be inserted only
% if this is not the first column. This process is controlled
% by \cs{if@firstamp} in the macro \cs{addamp}.
% \begin{macrocode}
\@addamp \@acol \or
% \end{macrocode}
% Class 2 is treated like class 0 because \verb?<{...}? can only
% follow after class 0.
% \begin{macrocode}
\@acolampacol \or
% \end{macrocode}
% Class 3 requires no actions because all things necessary have
% been done by the preamble \textsf{token} \texttt{>}.
% \begin{macrocode}
\or
% \end{macrocode}
% Class 4 means that we are at the beginning of the preamble.
% Therefore we start the preamble with \verb?\hskip\col@sep? and
% then call \cs{@firstampfalse}. This makes sure that a later
% \cs{@addamp} inserts the character
% \verb?&? into the preamble.
% \begin{macrocode}
\@acol \@firstampfalse \or
% \end{macrocode}
% For class 5 \textsf{tokens} only the character \verb?&? is inserted
% as a column separator. Therefore we call \cs{@addamp}.
% \begin{macrocode}
\@addamp
% \end{macrocode}
% Other cases are impossible. For an example
% \verb?\@lastchclass = 6? ---a s it might appear in a
% preamble of the form \verb?...!p...? --- \texttt{p} would have
% been taken as an argument of \texttt{!} by \cs{@testpach}.
% \begin{macrocode}
\fi}
% \end{macrocode}
% \end{macro}
%
%
% \begin{macro}{\@classz}
% If the character class of the last \textsf{token} is 0 we have
% \texttt{c}, \texttt{l}, \texttt{r} or an argument of \texttt{m},
% \texttt{b} or\ \texttt{p}. In the first three cases the preamble
% must be extended the same way as if we had class 10. The
% remaining two cases do not require any action because the space
% needed was generated by the last \textsf{token} (i.e.\
% \texttt{m}, \texttt{b} or \texttt{p}). Since \cs{@lastchclass} has
% the value 10 at this point nothing happens when \cs{@classx} is
% called. So the macro \cs{@chlassz} may start like this:
% \begin{macrocode}
\def\@classz{\@classx
% \end{macrocode}
% According to the definition of \cs{insert@column} we must store
% the number of the \textsf{token} register in which a preceding
% \verb?>{..}? might have stored its argument into
% \cs{@tempcnta}.
% \begin{macrocode}
\@tempcnta \count@
% \end{macrocode}
% To have \verb?\count@ = \@tmpcnta + 1? we prepare
% the next \textsf{token} register.
% \begin{macrocode}
\prepnext@tok
% \end{macrocode}
% Now the preamble must be extended with the column whose format
% can be determinated by \cs{@chnum}.
% \begin{macrocode}
\@addtopreamble{\ifcase \@chnum
% \end{macrocode}
% If \cs{@chnum} has the value 0 a centered column has to be
% generated.
% So we begin with stretchable space.
% \begin{macrocode}
\hfil
% \end{macrocode}
% The command \cs{d@llarbegin} follows expanding into \cs{begingroup}
% (in the \textsf{tabular}--environment) or into \verb?$?. Doing this
% (provided an appropriate setting of \cs{d@llarbegin}) we achieve
% that the contents of the columns of an \textsf{array}--environment
% are set in math mode while those of a \textsf{tabular}--environment
% are set in LR mode.
% \begin{macrocode}
\d@llarbegin
% \end{macrocode}
% Now we insert the contents of the two \textsf{token} registers
% and the symbol
% for the column entry (i.e.\ \verb?#? or
% more precise \cs{@sharp}) using \cs{insert@column}.
% \begin{macrocode}
\insert@column
% \end{macrocode}
% We end this case with \cs{d@llarend} and \cs{hfil} where \cs{d@llarend}
% again is either \verb?$? or \cs{endgroup}.
% \begin{macrocode}
\d@llarend \hfil \or
% \end{macrocode}
% The templates for \texttt{l} and \texttt{r} (i.e.\ \cs{@chnum} 1
% or 2) are generated the same way. Since one \cs{hfil} is
% missing the text is moved to the relevant side.
% The \verb?\kern\z@? is needed in case of an empty column
% entry. Otherwise
% the \cs{unskip} in \cs{insert@column} removes the
% \cs{hfil}. Changed to \verb?\hskip1sp? so that it interacts better with
% \cs{@bsphack}.
% \begin{macrocode}
\hskip1sp\d@llarbegin \insert@column \d@llarend \hfil \or
\hfil\hskip1sp\d@llarbegin \insert@column \d@llarend \or
% \end{macrocode}
% The templates for \texttt{p}, \texttt{m} and \texttt{b} mainly
% consist of a \textsf{box}. In case of \texttt{m} it is generated
% by \cs{vcenter}. This command is allowed only in math
% mode. Therefore we start with a~\verb?$?.
% \begin{macrocode}
$\vcenter%$
% \end{macrocode}
% The part of the templates which is the same in all three cases
% (\texttt{p}, \texttt{m} and \texttt{b})
% is built by the macros \cs{@startpbox} and
% \cs{@endpbox}. \cs{@startpbox} has an argument:
% the width of the column which is stored in the current
% \textsf{token} (i.e.\ \cs{@nextchar}).
% Between these two macros we find the well known
% \cs{insert@column}.
% \begin{macrocode}
\@startpbox{\@nextchar}\insert@column \@endpbox $\or%$
% \end{macrocode}
% The templates for \texttt{p} and \texttt{b} are generated in the
% same way though we do not need the \verb?$? characters because we use
% \cs{vtop} or \cs{vbox}.
% \begin{macrocode}
\vtop \@startpbox{\@nextchar}\insert@column \@endpbox \or
\vbox \@startpbox{\@nextchar}\insert@column \@endpbox
% \end{macrocode}
% Other values for \cs{@chnum} are impossible. Therefore we
% end the arguments to \cs{@addtopreamble} and \cs{ifcase}.
% Before we come to the end of \cs{@classz} we have to

% \begin{macrocode}

% The argument is the width of the box. This information has to be

% Then we assain default values to several parameters used in a
% \textsf{parbox}.
% \begin{macrocode}
\setlength\hsize{#1}\@arrayparboxrestore
% \end{macrocode}
% Our main problem is to obtain the same distance between succeeding
% lines of the \textsf{parbox}.
% We have to remember that the distance between two \textsf{parboxes}
% should be defined by \cs{@arstrut}. That means that it can be
% greater than the distance in a \textsf{parbox}.
% Therefore it is not enough to set a \cs{@arstrut} at the
% beginning and at the end of the \textsf{parbox}. This would
% dimension the distance
% between first and second line and the distance between the two
% last lines of the \textsf{parbox} wrongly.
% To prevent this we set an invisible rule of height

% at the beginning of the \textsf{parbox}. This has no effect on the

%
% \subsubsection{Building and calling \texttt{\textbackslash halign}}
%
% \begin{macro}{\@array}
% After we have discussed the macros needed for the evaluation
% of the user preamble we can define the macro \cs{@array}
% which uses these macros to create a \cs{halign}.
% It has two arguments. The first one is a position argument
% which can be \texttt{t}, \texttt{b} or \texttt{c}; the
% second one describes the wanted preamble,
% e.g.\ it has the form \verb?|c|c|c|?.
% \begin{macrocode}
\def\@array[#1]#2{%
% \end{macrocode}
% First we define a \textsf{strut} whose size basically corresponds
% to a normal \textsf{strut} multiplied by the factor
% \cs{arraystretch}.
% This \textsf{strut} is then inserted into every row and enforces
% a minimal distance between two rows.
% Nevertheless, when using horizontal lines, large letters
% (like accented capital letters) still collide with such lines.
% Therefore at first we add to the height of a normal \textsf{strut}
% the value of the parameter \cs{extrarowheight}.
% \begin{macrocode}
\@tempdima \ht \strutbox
\advance \@tempdima by\extrarowheight
\setbox \@arstrutbox \hbox{\vrule
\@height \arraystretch \@tempdima
\@depth \arraystretch \dp \strutbox
\@width \z@}%
% \end{macrocode}
% Then we open a group, in which the user preamble is evaluated by
% the macro \cs{@mkpream}. As we know this must happen locally.
% This macro creates a preamble for a \cs{halign} and saves
% its result globally in the control sequence \cs{@preamble}.
% \begin{macrocode}
\begingroup
\@mkpream{#2}%
% \end{macrocode}
% We again redefine \cs{@preamble} so that a call up of \cs{@preamble}
% now starts the \cs{halign}. Thus also the arguments of \texttt{>},
% \texttt{<}, \texttt{@} and \texttt{!}, saved in the
% \textsf{token} registers are inserted into the preamble. The
% \cs{tabskip} at the beginning and end of the preamble is set to
% \textsf{0pt} (in the beginning by the use of \cs{ialign}). Also the
% command \cs{@arstrut} is build in, which inserts the
% \cs{@arstrutbox}, defined above. Of course, the opening brace after
% \cs{ialign} has to be implicit as it will be closed in \cs{endarray}
% or another macro.
%
% The \cs{noexpand} in front of \cs{ialign} does no harm in standard \LaTeX{}
% and was added since some experimental support for using text glyphs in math
% redefines \cs{halign} with the result that is becomes expandable with
% disastrous results in cases like this.
% In the kernel definition for this macro the problem does
% not surface because there \cs{protect} is set (which is not necessary in this
% implementation as there is no arbitrary user input that can get expanded) and
% the experimental code made the redefinition robust. Whether this is the right
% approach is open to question; consider the \cs{noexpand} a curtesy to allow an
% unsupported redefinition of a \TeX{} primitive for the moment (as people rely
% on that experimental code).
% \begin{macrocode}
\xdef\@preamble{\noexpand \ialign \@halignto
\bgroup \@arstrut \@preamble
\tabskip \z@ \cr}%
% \end{macrocode}
% What we have not explained yet is the macro \cs{@halignto}
% that was just used. Depending on its replacement text the
% \cs{halign} becomes a \cs{halign} \texttt{to} \meta{dimen}.
% Now we close the group again. Thus
% \cs{@startpbox} and \cs{@endpbox} as well as all
% \textsf{token} registers get their former meaning back.
% \begin{macrocode}
\endgroup
% \end{macrocode}
% To support other packages we include a hook
% into this part of the code which is a no-op in the main package.
% \begin{macrocode}
\@arrayleft
% \end{macrocode}
% Now we decide depending on the position argument in which
% \textsf{box} the \cs{halign} is to be put. (\cs{vcenter} may be used
% because we are in math mode.)
% \begin{macrocode}
\if #1t\vtop \else \if#1b\vbox \else \vcenter \fi \fi
% \end{macrocode}
% Now another implicit opening brace appears; then definitions
% which shall stay local follow. While constructing the
% \cs{@preamble} in \cs{@mkpream} the \verb?#? sign must be
% hidden in the macro \cs{@sharp} which is \cs{let} to
% \cs{relax} at that moment (see definition of \cs{@mkpream}).
% All these now get their actual meaning.
% \begin{macrocode}
\bgroup
\let \@sharp ##\let \protect \relax
% \end{macrocode}
% With the above defined \textsf{struts} we fix down the distance
% between rows by setting \cs{lineskip} and \cs{baselineskip}
% to \textsf{0pt}. Since there have to be set \verb?$?'s
% around every column in the \textsf{array}--environment
% the parameter \cs{mathsurround} should
% also be set to \textsf{0pt}. This prevents additional space between
% the rows. The
% \PlainTeX--macro \cs{m@th} does this.
% \begin{macrocode}
\lineskip \z@
\baselineskip \z@
\m@th
% \end{macrocode}
% Beside, we have to assign a special meaning (which we still have
% to specify) to the line separator \verb?\\?. We also have to
% redefine the command \cs{par} in such a way that empty lines in
% \cs{halign} cannot do any damage. We succeed in doing so
% by choosing something that will disappear when expanding.
% After that we only have to call up \cs{@preamble} to
% start the wanted \cs{halign}.
% \begin{macrocode}
\let\\\@arraycr \let\tabularnewline\\\let\par\@empty \@preamble}
% \end{macrocode}
% \end{macro}
%
%
% \begin{macro}{\extrarowheight}
% The \textsf{dimen} parameter used above also needs to be
% allocated. As a default value we use \textsf{0pt}, to ensure
% compatibility with standard \LaTeX.
% \begin{macrocode}
\newdimen \extrarowheight
\extrarowheight=0pt
% \end{macrocode}
% \end{macro}
%
% \begin{macro}{\@arstrut}
% Now the insertion of \cs{@arstrutbox} through \cs{@arstut}
% is easy since we know exactly in which mode \TeX\ is while working
% on the \cs{halign} preamble.
% \begin{macrocode}
\def\@arstrut{\unhcopy\@arstrutbox}
% \end{macrocode}
% \end{macro}
%
%
% \subsubsection{The line separator \texttt{\textbackslash\textbackslash}}
%
% \begin{macro}{\@arraycr}
% In the macro \cs{@array} the line separator \verb?\\? is
% \cs{let} to the command \cs{@arraycr}.
% Its definition starts with a special brace which I have directly
% copied from the original definition. It is
% necessary, because the \cs{futurlet} in \cs{@ifnextchar}
% might
% expand a following \verb?&? \textsf{token} in a construction like
% \verb?\\ &?. This would otherwise end the alignment template at a
% wrong time. On the other hand we have to be careful to avoid
% producing a real group, i.e., \verb?{}?, because the command will also
% be used for the array environment, i.e., in math mode. In that
% case an extra \verb?{}? would produce an ord atom which could mess up
% the spacing. For this reason we use a combination that does not
% really produce a group at all but modifies the master counter so
% that a \verb?&? will not be considered belonging to the current
% \cs{halign} while we are looking for a \verb?*? or \verb?[?.
% For further information see
% \cite[Appendix D]{bk:knuth}.
% \begin{macrocode}
\def\@arraycr{\relax\iffalse{\fi\ifnum 0=`}\fi
% \end{macrocode}
% Then we test whether the user is using the star form and ignore
% a possible star (I also disagree with this procedure, because a
% star does not make any sense here).
% \begin{macrocode}
\@ifstar \@xarraycr \@xarraycr}
% \end{macrocode}
% \end{macro}
%
% \begin{macro}{\@xarraycr}
% In the command \cs{@xarraycr} we test if an optional argument
% exists.
% \begin{macrocode}
\def\@xarraycr{\@ifnextchar [%
% \end{macrocode}
% If it does, we branch out into the macro \cs{@argarraycr} if
% not we close the special brace (mentioned above) and end the row
% of the \cs{halign} with a \cs{cr}.
% \begin{macrocode}
\@argarraycr {\ifnum 0=`{}\fi\cr}}
% \end{macrocode}
% \end{macro}
%
%
% \begin{macro}{\@argarraycr}
% If additional space is requested by the user this case is treated
% in the macro \cs{@argarraycr}. First we close the special brace
% and then we test if the additional space is positive.
% \begin{macrocode}
\def\@argarraycr[#1]{\ifnum0=`{}\fi\ifdim #1>\z@
% \end{macrocode}
% If this is the case we create an invisible vertical rule with
% depth \verb?\dp\@arstutbox?${}+{}$\meta{wanted\ space}.
% Thus we achieve that all vertical lines specified
% in the user preamble by a \verb?|? are now
% generally drawn.
% Then the row ends with a \cs{cr}.
%
% If the space is negative we end the row at once with a \cs{cr}
% and move back up with a \cs{vskip}.
%
% While testing these macros I found out that the
% \cs{endtemplate}
% created by \cs{cr} and \verb?&? is something like an
% \cs{outer} primitive and therefore it should not appear in
% incomplete \cs{if} statements. Thus the following solution was
% chosen which hides the \cs{cr} in other macros when \TeX\
% is skipping conditional text.
% \begin{macrocode}
\expandafter\@xargarraycr\else
\expandafter\@yargarraycr\fi{#1}}
% \end{macrocode}
% \end{macro}
%
% \begin{macro}{\@xargarraycr}
% \begin{macro}{\@yargarraycr}
% The following macros were already explained above.
% \begin{macrocode}
\def\@xargarraycr#1{\unskip
\@tempdima #1\advance\@tempdima \dp\@arstrutbox
\vrule \@depth\@tempdima \@width\z@ \cr}
\def\@yargarraycr#1{\cr\noalign{\vskip #1}}
% \end{macrocode}
% \end{macro}
% \end{macro}
%
%
%
%
% \subsubsection{Spanning several columns}
%
% \begin{macro}{\multicolumn}
% If several columns should be held together with a special format
% the command \cs{multicolumn} must be used. It has three
% arguments: the number of columns to be covered; the format for
% the result column and the actual column entry.
% \begin{macrocode}
\long\def\multicolumn#1#2#3{%
% \end{macrocode}
% First we combine the given number of columns into a single one;
% then we start a new block so that the following definition is kept
% local.
% \begin{macrocode}
\multispan{#1}\begingroup
% \end{macrocode}
% Since a \cs{multicolumn} should only describe the format of a
% result column, we redefine \cs{@addamp} in such a way that one gets
% an error message if one uses more than one \texttt{c},
% \texttt{l}, \texttt{r}, \texttt{p}, \texttt{m} or \texttt{b} in
% the second argument. One should consider that this definition is
% local to the build-up of the preamble; an \textsf{array}-- or
% \textsf{tabular}--environment in the third argument of the
% \cs{multicolumn} is therefore worked through correctly as well.
% \begin{macrocode}
\def\@addamp{\if@firstamp \@firstampfalse \else
\@preamerr 5\fi}%
% \end{macrocode}
% Then we evaluate the second argument with the help of
% \cs{@mkpream}.
% Now we still have to insert the contents of the \textsf{token}
% register into the \cs{@preamble}, i.e.\ we have to say
% \verb?\xdef\@preamble{\@preamble}?. This is achieved shorter by
% writing:
% \begin{macrocode}
\@mkpream{#2}\@addtopreamble\@empty
% \end{macrocode}
% After the \cs{@preamble} is created we forget all local
% definitions and occupations of the \textsf{token} registers.
% \begin{macrocode}
\endgroup
% \end{macrocode}
% In the special situation of \cs{multicolumn} \cs{@preamble}
% is not needed as preamble for a \cs{halign} but it is directly
% inserted into our table. Thus instead of \cs{sharp}
% there has to be the column entry (\verb?#3?) wanted by the user.
% \begin{macrocode}
\def\@sharp{#3}%
% \end{macrocode}
% Now we can pass the \cs{@preamble} to \TeX\ . For safety
% we start with an \cs{@arstrut}. This should usually be in the
% template for the first column however we do not know if this
% template was overwritten by our \cs{multicolumn}.
% We also add a \cs{null} at the right end to prevent any following
% \cs{unskip} (for example from \verb?\\[..]?) to remove the \cs{tabcolsep}.
% \begin{macrocode}
\@arstrut \@preamble
\null
\ignorespaces}
% \end{macrocode}
% \end{macro}
%
%
%
% \subsubsection{The environment definitions}
%
% After these preparations we are able to define the environments. They
% only differ in the initialisations of \cs{d@llar...}, \cs{col@sep}
% and \cs{@halignto}.
%
% \begin{macro}{\@halignto}
% \begin{macro}{\d@llarbegin}
% \begin{macro}{\d@llarend}
% In order to relieve the \textsf{save stack} we assign the
% replacement texts for \cs{@halignto} globally. \cs{d@llar} has to be
% local since otherwise nested \textsf{tabular} and \textsf{array}
% environments (via \cs{multicolumn}) are impossible.
% When the new font selection scheme is in force we have to
% we surround all \cs{halign} entries
% with braces. See remarks in TUGboat 10\#2. Actually we are going
% to use \cs{begingroup} and \cs{endgroup}. However, this is only
% necessary when we are in text mode. In math the surrounding
% dollar signs will already serve as the necessary extra grouping
% level. Therefore we switch the settings of \cs{d@llarbegin} and
% \cs{d@llarend} between groups and dollar signs.
% \begin{macrocode}
\let\d@llarbegin\begingroup
\let\d@llarend\endgroup
% \end{macrocode}
% \end{macro}
% \end{macro}
% \end{macro}
%
%
% \begin{macro}{\array}
% Our new definition of \cs{array} then reads:
% \begin{macrocode}
\def\array{\col@sep\arraycolsep
\def\d@llarbegin{$}\let\d@llarend\d@llarbegin\gdef\@halignto{}%$
% \end{macrocode}
% Since there might be an optional argument we call another
% macro which is also used by the other environments.
% \begin{macrocode}
\@tabarray}
% \end{macrocode}
% \end{macro}
%
%
% \begin{macro}{\@tabarray}
% This macro tests for an optional bracket and then calls up
% \cs{@@array} or \verb?\@@array[c]? (as default).
% \begin{macrocode}
\def\@tabarray{\@ifnextchar[{\@@array}{\@@array[c]}}
% \end{macrocode}
% \end{macro}
% \begin{macro}{\@@array}
% This macro could then test an optional delimiter before the
% left brace of the main preamble argument. At this point
% it simply is let to be \cs{@array}.
% \begin{macrocode}
\let\@@array\@array
% \end{macrocode}
% \end{macro}
%
%
% \begin{macro}{\tabular}
% \begin{macro}{\tabular*}
% The environments \textsf{tabular} and \textsf{tabular*} differ
% only in the initialisation of the command \cs{@halignto}. Therefore
% we define
% \begin{macrocode}
\def\tabular{\gdef\@halignto{}\@tabular}
% \end{macrocode}
% and analoguesly for the star form. We evalute the argument first
% using \cs{setlength} so that users of the \texttt{calc} package can
% write code like\\ \verb?\begin{tabular*}{(\columnwidth-1cm)/2}...?
% \begin{macrocode}
\expandafter\def\csname tabular*\endcsname#1{%
\setlength\dimen@{#1}%
\xdef\@halignto{to\the\dimen@}\@tabular}
% \end{macrocode}
% \end{macro}
% \end{macro}
%
% \begin{macro}{\@tabular}
% The rest of the job is carried out by the \cs{@tabular} macro:
% \begin{macrocode}
\def\@tabular{%
% \end{macrocode}
% First of all we have to make sure that we start out in
% \textsf{hmode}. Otherwise we might find our table dangling by
% itself on a line.
% \begin{macrocode}
\leavevmode
% \end{macrocode}
% It should be taken into consideration that the macro \cs{@array}
% must be called in math mode. Therefore we open a \textsf{box},
% insert a \verb?$? and then assign the correct values to \cs{col@sep} and
% \cs{d@llar...}.
% \begin{macrocode}
\hbox \bgroup $\col@sep\tabcolsep \let\d@llarbegin\begingroup%$
\let\d@llarend\endgroup
% \end{macrocode}
% Now everything \textsf{tabular} specific is done and we are able to
% call the \cs{@tabarray} macro.
% \begin{macrocode}
\@tabarray}
% \end{macrocode}
% \end{macro}
%
%
% \begin{macro}{\endarray}
% \begin{macro}{\@arrayleft}
% \begin{macro}{\@arrayright}
% When the processing of \textsf{array} is finished we have to
% close the \cs{halign}
% and afterwards the surrounding \textsf{box} selected by
% \cs{@array}. To save \textsf{token} space we then redefine
% \cs{@preamble}
% because its replacement text isn't longer needed.
% We have to declare the hook, \cs{@arrayleft}, we put into \cs{@array} above.
% A similar hook `\cs{@arrayright}' is inserted into the
% \cs{endarray} to gain control. Both defaults to empty.
% \begin{macrocode}
\def\endarray{\crcr \egroup \egroup \@arrayright \gdef\@preamble{}}
\let\@arrayleft\@empty
\let\@arrayright\@empty
% \end{macrocode}
% \end{macro}
% \end{macro}
% \end{macro}
%
% \begin{macro}{\endtabular}
% \begin{macro}{\endtabular*}
% To end a \textsf{tabular} or \textsf{tabular*} environment we
% call up \cs{endarray}, close the math mode and then the surrounding
% \cs{hbox}.
% \begin{macrocode}
\def\endtabular{\endarray $\egroup}%$
\expandafter\let\csname endtabular*\endcsname=\endtabular
% \end{macrocode}
% \end{macro}
% \end{macro}
%
% We should \cs{let} all macros
% to \cs{relax} that were used in the kernel but are no longer
% necessary.
% \begin{macrocode}
\let\@ampacol=\relax \let\@expast=\relax
\let\@arrayclassiv=\relax \let\@arrayclassz=\relax
\let\@tabclassiv=\relax \let\@tabclassz=\relax
\let\@arrayacol=\relax \let\@tabacol=\relax
\let\@tabularcr=\relax \let\@@endpbox=\relax
\let\@argtabularcr=\relax \let\@xtabularcr=\relax
% \end{macrocode}
%
% \begin{macro}{\@preamerr}
% We also have to redefine the error routine \cs{@preamerr} since
% new kind of errors are possible.
% The code for this macro is not perfect yet;
% it still needs too much memory.
% \begin{macrocode}
\def\@preamerr#1{\def\@tempd{{..} at wrong position: }%
\ClassError{memoir}{%
\ifcase #1 Illegal pream-token (\@nextchar): `c' used\or %0

<\@tempd changed to !{..}\or %4
Only one column-spec. allowed.\fi}\@ehc} %5
% \end{macrocode}
% \end{macro}
%
%
%
% \subsubsection{Defining your own column specifiers}
%
%
% \begin{macro}{\newcolumntype}
% In \texttt{newarray.sty} the macro for specifying new columns was
% named \cs{newcolumn}. When the functionality was added to
% \texttt{array.sty} the command was renamed \cs{newcolumntype}.
% The \cs{newcolumntype} macro gives users the chance
% to define letters, to be used in the same way as the primitive
% column specifiers, `c' `p' etc.
% \begin{macrocode}
\def\newcolumntype#1{%
% \end{macrocode}
% \cs{NC@char} is so that active characters, like \verb?@? in
% AMS\LaTeX\ may be used. Note that we need to use the possibly active token,
% \verb?#1?, in several places, as that is the token that actually
% appears in the preamble argument.
% \begin{macrocode}
\edef\NC@char{\string#1}%
% \end{macrocode}
% First we check whether there is already a definition for this column.
% Unlike \cs{newcommand} we give a warning rather than an error if it is
% defined. If it is a new column, add \cs{NC@do} \meta{column} to
% the list \cs{NC@list}.
% \begin{macrocode}
\@ifundefined{NC@find@\NC@char}%
{\@tfor\next:=<>clrmbp@!|\do{\if\noexpand\next\NC@char
\@memwarn{Redefining primitive column \NC@char}\fi}%
\NC@list\expandafter{\the\NC@list\NC@do#1}}%
{\@memwarn{Column \NC@char\space is already defined}}%
% \end{macrocode}
% Now we define a macro with an argument delimited by the new column
% specifier, this is used to find occurences of this specifier in the
% user preamble.
% \begin{macrocode}
\@namedef{NC@find@\NC@char}##1#1{\NC@{##1}}%
% \end{macrocode}
% If an optional argument was not given, give a default argument of 0.
% \begin{macrocode}
\@ifnextchar[{\newcol@{\NC@char}}{\newcol@{\NC@char}[0]}}
% \end{macrocode}
% \end{macro}
% \begin{macro}{\newcol@}
% We can now define the macro which does the rewriting,
% \cs{@reargdef} takes the same arguments as \cs{newcommand}, but
% does not check that the command is new. For a column, say `D' with
% one argument, define a command \cs{NC@rewrite@D} with one
% argument, which recursively calls \cs{NC@find} on the user preamble
% after replacing the first token or group with the replacement text
% specified in the \cs{newcolumntype} command. \cs{NC@find} will find the
% next occurrence of `D' as it will be \cs{let} equal to
% \cs{NC@find@D} by \cs{NC@do}.
% \begin{macrocode}
\def\newcol@#1[#2]#3{\expandafter\@reargdef
\csname NC@rewrite@#1\endcsname[#2]{\NC@find#3}}
% \end{macrocode}
% \end{macro}
% \begin{macro}{\NC@}
% Having found an occurence of the new column, save the preamble
% before the column in \cs{@temptokena}, then check to see if we
% are at the end of the preamble. (A dummy occurrence of the column
% specifier will be placed at the end of the preamble by \cs{NC@do}).
% \begin{macrocode}
\def\NC@#1{%
\@temptokena\expandafter{\the\@temptokena#1}\futurelet\next\NC@ifend}
% \end{macrocode}
% \end{macro}
% \begin{macro}{\NC@ifend}
% We can tell that we are at the end as \cs{NC@do} will place a \cs{relax}
% after the dummy column.
% \begin{macrocode}
\def\NC@ifend{%
% \end{macrocode}
% If we are at the end, do nothing. (The whole preamble will now be in
% \cs{@temptokena}.)
% \begin{macrocode}
\ifx\next\relax
% \end{macrocode}
% Otherwise set the flag \cs{if@tempswa}, and rewrite the column.
% \begin{macrocode}
\else\@tempswatrue\expandafter\NC@rewrite\fi}
% \end{macrocode}
% \end{macro}
% \begin{macro}{\NC@do}
% If the user has specified `C' and `L' as new columns, the list of
% rewrites (in the token register \cs{NC@list}) will look like
% \verb?\NC@do *? \verb?\NC@do C? \verb?\NC@do L?.
% So we need to define \cs{NC@do} as a one argument macro which
% initialises the rewriting of the specified column. Let us assume that
% `C' is the argument.
% \begin{macrocode}
\def\NC@do#1{%
% \end{macrocode}
% First we let \cs{NC@rewrite} and \cs{NC@find} be
% \cs{NC@rewrite@C} and \cs{NC@find@C} respectively.
% \begin{macrocode}
\expandafter\let\expandafter\NC@rewrite
\csname NC@rewrite@\string#1\endcsname
\expandafter\let\expandafter\NC@find
\csname NC@find@\string#1\endcsname
% \end{macrocode}
% Clear the token register \cs{@temptokena} after putting the present
% contents of the register in front of the token \cs{NC@find}. At the
% end we place the tokens `\verb?C\relax?' which \cs{NC@ifend} will use
% to detect the end of the user preamble.
% \begin{macrocode}
\expandafter\@temptokena\expandafter{\expandafter}%
\expandafter\NC@find\the\@temptokena#1\relax}
% \end{macrocode}
% \end{macro}
%
% \begin{macro}{\showcols}
% This macro is useful for debugging \cs{newcolumntype} specifications,
% it is the equivalent of the primitive \cs{show} command for macro
% definitions. All we need to do is locally redefine \cs{NC@do} to take
% its argument (say `C') and then \cs{show} the (slightly modified)
% definition of \cs{NC@rewrite@C}. Actually as the the list always
% starts off with \verb?\NC@do *? and we do not want to print the
% definition of the *-form, define \cs{NC@do} to throw away the first
% item in the list, and then redefine itsef to print the rest of the
% definitions.
% \begin{macrocode}
\def\showcols{{\def\NC@do##1{\let\NC@do\NC@show}\the\NC@list}}
% \end{macrocode}
% \end{macro}
% \begin{macro}{\NC@show}
% If the column `C' is defined as above, then
% \verb?\show\NC@rewrite@C? would output\\
% \verb?\long macro: ->\NC@find >{$}c<{$}?.
% We want to strip the \verb?\long macro: ->? and the \cs{NC@find}. So first we
% use \cs{meaning} and then apply the macro \cs{NC@strip} to the tokens so
% produced and then \cs{typeout} the required string.
% \begin{macrocode}
\def\NC@show#1{%
\typeout{Column #1\expandafter\expandafter\expandafter\NC@strip
\expandafter\meaning\csname NC@rewrite@#1\endcsname\@@}}
% \end{macrocode}
% \end{macro}
% \begin{macro}{\NC@strip}
% Delimit the arguments to \cs{NC@strip} with `\texttt{:}', `\texttt{->}',
% a space, and \cs{@@} to pull out the required parts of the output from
% \cs{meaning}.
% \begin{macrocode}
\def\NC@strip#1:#2->#3 #4\@@{#2 -> #4}
% \end{macrocode}
% \end{macro}
% \begin{macro}{\NC@list}
% Allocate the token register used for the rewrite list.
% \begin{macrocode}
\newtoks\NC@list
% \end{macrocode}
% \end{macro}
%
% \subsubsection{The *--form}
% We view the *-form as a slight generalisation of the system
% described in the previous subsection. The idea is to define a *
% column by a command of the form:
% \begin{verbatim}
% \newcolumntype{*}[2]{%
% \count@=#1\ifnum\count@>0
% \advance\count@ by -1 #2*{\count@}{#2}\fi}
% \end{verbatim}
% \begin{macro}{\NC@rewrite@*}\label{NC@rewrite@*}
% This does not work however as \cs{newcolumntype} takes great care not
% to expand anything in the preamble, and so the \cs{if} is never
% expanded. \cs{newcolumntype} sets up various other parts of the
% rewrite correctly though so we can define:
% \begin{macrocode}
\newcolumntype{*}[2]{}
% \end{macrocode}
% Now we must correct the definition of \cs{NC@rewrite@*}. The
% following is probably more efficient than a direct translation of
% the idea sketched above, we do not need to put a * in the preamble
% and call the rewrite recursively, we can just put \verb?#1? copies of
% \verb?#2? into \cs{@temptokena}. (Nested * forms will be expanded
% when the whole rewrite list is expanded again, see \cs{@mkpream})
% \changes{v1.618}{2005/09/03}{Fixed original bug in \cs{NC@rewrite@*} (mempatch v3.3)}
% \begin{macrocode}
\long\@namedef{NC@rewrite@*}#1#2{%
% \end{macrocode}
% Store the number.
% \begin{macrocode}
\count@#1\relax
% \end{macrocode}
% Put \verb?#1? copies of \verb?#2? in the token register.
% \begin{macrocode}
\loop
\ifnum\count@>\z@
\advance\count@\m@ne
\@temptokena\expandafter{\the\@temptokena#2}%
\repeat
% \end{macrocode}
% \cs{NC@do} will ensure that \cs{NC@find} is \cs{let} equal
% to \cs{NC@find@*}.
% \begin{macrocode}
\NC@find}
% \end{macrocode}
% \end{macro}
%
%
% \subsection{Getting the spacing around rules right}
%
% The Companion~\cite[p.137]{GOOSSENS94} suggests two additional
% commands to control the allignments in case of tabulars with
% horizontal lines. They are now added to this package.
%
% \begin{macro}{\extratabsurround}
% The extra space around a table when \cs{firsthline} or \cs{lasthline}
% are used.
% \begin{macrocode}
\newlength{\extratabsurround}
\setlength{\extratabsurround}{2pt}
% \end{macrocode}
% \end{macro}
%
% \begin{macro}{\backup@length}
% This register will be used internally by \cs{firsthline} and
% \cs{lasthline}.
% \begin{macrocode}
\newlength{\backup@length}
% \end{macrocode}
% \end{macro}
%
% \begin{macro}{\firsthline}
% This code can probably be improved but for the moment it should
% serve.
%
% We start by producing a single tabular row without any visible
% content that will produce the external reference point in case
% \verb?[t]? is used.
% \begin{macrocode}
\newcommand{\firsthline}{%
\multicolumn1c{%
% \end{macrocode}
% Within this row we calculate \cs{backup@length} to be the height
% plus depth of a standard line. In addition we have to add the
% width of the \cs{hline}, something that was forgotten in the
% original definition.
% \begin{macrocode}
\global\backup@length\ht\@arstrutbox
\global\advance\backup@length\dp\@arstrutbox
\global\advance\backup@length\arrayrulewidth
% \end{macrocode}
% Finally we do want to make the height of this first line be a bit
% larger than usual, for this we place the standard array strut
% into it but raised by \cs{extratabsurround}
% \begin{macrocode}
\raise\extratabsurround\copy\@arstrutbox
% \end{macrocode}
% Having done all this we end the line and back up by the value of
% \cs{backup@length} and then finally place our \cs{hline}. This should
% place the line exactly at the right place but keep the reference
% point of the whole tabular at the baseline of the first row.
% \begin{macrocode}
}\\[-\backup@length]\hline
}
% \end{macrocode}
% \end{macro}
%
% \begin{macro}{\lasthline}
% For \cs{lasthline} the situation is even worse and I got it
% completely wrong initially.
%
% The problem in this case is that if the optional argument \verb?[b]?
% is used we do want the reference point of the tabular be at the
% baseline of the last row but at the same time do want the the
% depth of this last line increased by \cs{extratabsurround} without
% changing the placement \cs{hline}.
%
% We start by placing the rule followed by an invisible row.
% \begin{macrocode}
\newcommand{\lasthline}{\hline\multicolumn1c{%
% \end{macrocode}
% We now calculate \cs{backup@length} to be the height and depth of
% two lines plus the width of the rule.
% \begin{macrocode}

%
%
% The \Lpack{dcolumn} package~\cite{DCOLUMN} defines \texttt{D}
% to be a column specifier
% with three arguments.\\
% \verb?D?\marg{sep.tex}\marg{sep.dvi}\marg{decimal places}
% for columns which are to be aligned on a `decimal point'.
%
%
% The basic ideas behind these macros have been explained earlier.
% However they use three
% tricks which may be useful in other contexts.
% \begin{itemize}
% \item The separator is surrounded in extra \verb?{ }?, so that it is set
% with \cs{mathord} spacing, otherwise, for instance a `,' would have
% extra space after it.
% \item The separator is not given its special definition by making it
% active, as this would not work for an entry such as \verb?& .5 &?, as the
% first token of an alignment entry is read \emph{before} the preamble
% part, incase it is an \cs{omit}, in which case the preamble is to be
% omitted. Instead we switch the mathcode to (hex) 8000, which makes the
% token act as if it were active.
% \item Although \verb?\mathcode`.="8000? makes \texttt{.} act as if it
% were active, it is still not allowed in constructions such as
% \verb?\def.{}?, even in math-mode, so we have to construct an active
% version of the separator, this is done by making it the uppercase of
% \verb?~?, and then using the construct\\
% \verb?\uppercase{\def~}?\marg{definition}.\\
% Note that the \meta{definition} is not uppercased, so the definition
% can refer to the standard, non-active use of the separator.
% \end{itemize}

% The following line is completely redundant but it does catch errors

% \subsection{The tabularx environment}
%
% The code and description are essentially from David Carlisle's
% \Lpack{tabularx} package~\cite{TABULARX}, v2.07 1999/01/07.
%
% \begin{macrocode}
%%%%%%%%%% Tabularx package code %%%%%%%%%%%%%%%%%%%%%
%%%%%%%%%% With acknowledgements to David Carlisle %%%%%%%%%%%%%%%%%%%%%
% \end{macrocode}
%
%
% The \Lpack{tabularx} package~\cite{TABULARX} implements a version of the \texttt{tabular}
% environment in which the widths of certain columns are calculated so
% that the table is is a specified width. The columns that may stretch are
% marked by an \texttt{X} in the preamble argument.
%
%
% First some registers etc.\ that we need.
% \begin{macrocode}
\newdimen\TX@col@width
\newdimen\TX@old@table
\newdimen\TX@old@col
\newdimen\TX@target
\newdimen\TX@delta
\newcount\TX@cols
\newif\ifTX@
% \end{macrocode}
%
% Now a trick to get the body of an environment into a token register,
% without doing any expansion. This does not do any real checking of
% nested environments, so if you should need to nest one {\ttfamily
% tabularx} inside another, the inner one must be surrounded by \verb?{ }?.
%
% \begin{macro}{\tabularx}
% Just save
% the width specification separately, then clear the token register
% \cs{toks@}.
% Finally call \cs{TX@get@body} to begin saving the body of the table.
% The \verb?{\ifnum0=`}\fi? allows \verb?tabularx? to appear
% inside a \cs{halign}.^^A
% \setbox0=\hbox{\footnotesize\verb?\iffalse{\fi\ifnum0=`}\fi?}^^A
% \setbox2=\hbox{\footnotesize\verb?\ifnum0=`{}\fi?}^^A
% \footnote{This adds an extra level of grouping,
% which is not really needed. Instead, I could use \box0\ here, and
% \box2\ below, however the code here would then have to be moved after
% the first line, because of the footnote to page 386 of \theTeXbook,
% and I do not think I should be writing code that is so obscure as to
% be documented in a footnote in an appendix called ``Dirty Tricks''!}
%
% This mechanism of grabbing an environment body does have the
% disadvantage (shared with the AMS alignment environments) that you
% can not make extension environments by code such as
%\begin{verbatim}
%\newenvironment{foo}{\begin{tabularx}{XX}}{\end{tabularx}}
%\end{verbatim}
% as the code is looking for a literal string \verb?\end{tabularx}? to stop
% scanning. One may avoid this problem by using
% \cs{tabularx} and \cs{endtabularx} directly in the definition:
%\begin{verbatim}
%\newenvironment{foo}{\tabularx{XX}}{\endtabularx}
%\end{verbatim}
% The scanner now looks for the end of the current environment (\verb?foo? in
% this example.) There are some restrictions on this usage, the
% principal one being that \cs{endtabularx} is the \emph{first} token of
% the `end code' of the environment.
% \begin{macrocode}
\def\tabularx#1{%
% \end{macrocode}

%
% Now that all the parts of the table specification are stored in
% registers, we can begin the work of setting the table.
%
% The algorithm for finding the correct column widths is as follows.
% Firstly set the table with each \texttt{X} column the width of the
% final table. Assuming that there is at least one \texttt{X} column,
% this will produce a table that is too wide. Divide the excess width by
% the number of \texttt{X} columns, and reduce the column width by
% this amount. Reset the table. If the table is not now the correct
% width, a \cs{multicolumn} entry must be `hiding' one of the {\ttfamily
% X} columns, and so there is one less \texttt{X} column affecting
% the width of the table. So we reduce by 1 the number of X columns and
% repeat the process.
%
% \begin{macro}{\TX@endtabularx}

% This last section was added at Version 1.02. Previous versions
% documentented the fact that \cs{verb} did not work inside {\ttfamily
% tabularx}, but that did not stop people using it! This usually put
% \LaTeX\ into an irrecoverable error position, with error messages that
% did not mention the cause of the error. The `poor man's \cs{verb}' (and
% \cs{verb*}) defined here is based on page 382 of \theTeXbook. As
% explained there, doing verbatim this way means that spaces are not
% treated correctly, and so \cs{verb*} may well be useless, however I
% consider this section of code to be error-recovery, rather than a real
% implementation of verbatim.
%
% The mechanism is quite general, and any macro which wants to allow a
% form of \cs{verb} to be used within its argument may
% \verb?\let\verb=\TX@verb?. (Making sure to restore the real definition
% later!)
%
% \cs{verb} and \cs{verb*} are subject to the following restictions:
% \begin{enumerate}
% \item Spaces in the argument are not read verbatim, but may be skipped
% according to \TeX's usual rules.
% \item Spaces will be added to the output after control words, even if
% they were not present in the input.
% \item Unless the argument is a single space, any trailing space,
% whether in the original argument, or added as in (2),
% will be omitted.
% \item The argument must not end with \verb?\?, so \verb?\verb|\|? is not
% allowed, however, because of (3), \verb?\verb|\ |? produces
% \verb?\?.
% \item The argument must be balanced with respect to \verb?{? and \verb?}?. So
% \verb?\verb|{|? is not allowed.
% \item A comment character like \verb?%? will not appear verbatim. It will
% act as usual, commenting out the rest of the input line!
% \item The combinations \verb=?`= and \verb?!`? will appear as
% {\ttfamily?`} and {\ttfamily!`} if the \texttt{cmtt} font is
% being used.
% \end{enumerate}
%
% \begin{macro}{\TX@verb}
% The internal definition of \cs{verb}. Spaces will be replaced by \verb?~?, so

% \verb?&? to appear in the argument.

% braces from such a group. The `\verb?!?' will be removed later.
%
% Originally I followed Knuth, and had \verb?\def\@tempa{##1}?, however this
% did not allow \verb?#? to appear in the argument. So I changed

% \subsubsection{Full width rules}
%
% When we are not in a \texttt{longtable} environment, we can simply
% implement the full width rules as a \cs{hrule} in a \verb?\noalign{}?
% group. But within a \texttt{longtable}, the rule has to be drawn like a
% \verb?\cmidrule{1-\LT@cols}? (the rationale for this is explained in the
% \texttt{longtable} documentation).
% In order to allow for both, all the rule macros have to
% open a \cs{noalign} group immediately, while they work out whether
% they have been called within a \texttt{longtable}; if you don't do this,
% \TeX's underlying \cs{halign} process gets hiccups.
% I use \LaTeX's
% dirty trick (\verb?\ifnum=0`}?) to fool the parser that the bracket
% count is OK. The bracket really gets closed after all the skipping
% at the end of the \cs{@BTendrule} macro.
% The class 1 rules, and \cs{specialrule}, really only differ in the
% defaults for space above and
% below, and the width, passed to a common routine, \cs{@BTrule},
% described below. The spaces, \cs{@aboverulesep} and \cs{@belowrulesep},
% are set within the \cs{noalign} group, so are inherited by
% \cs{@BTrule}. Similarly, \cs{@BTrule} knows as much as it needs to
% about the routine that called it by examining the inherited
% \cs{@thisruleclass}. The optional width argument is parsed by
% \cs{@BTrule} after being set to default if absent.

% \begin{macro}{\addlinespace}
% An \cs{addlinespace} is essentially a zero-width rule with

% need to check if we're in a longtable, so we don't need to call
% \cs{@BTrule} as for `real' rules. But we do share the \cs{@BTendrule}
% lookahead and flagsetting code (described below), and the \cs{vskip} is done there.
% \begin{macrocode}

% \end{macrocode}
% After text (last rule class 0), precede the rule by \cs{aboverulesep};
% but if immediately after a
% previous rule, insert a \cs{doublerulesep}.
%
% Now we work out, by a very nasty hack, if we're within a
% \texttt{longtable}. It's easy if \cs{longtable} isn't even defined: then we
% can't be. But it is not enough just to check if \texttt{longtable} is
% loaded --- we might be within an ordinary table rather than a
% longtable. So we look to see if \cs{hline} has been re-defined
% from its \LaTeX\ definition to be the same as
% \cs{LT@hline}. (Longtable currently does this redefinition when it opens a
% \texttt{longtable} environment, but not globally, so it is
% cleared it when the environment closes.) Another
% package could potentially do this! And \texttt{longtable} might change the
% way it implements this! So, it is not entirely safe, but I have
% found no better way so far.

% which are zero by default, set to \cs{cmidrulekern} by the plain
% \verb?(lr)? arguments, or user set as in \verb?(r{.5em})?. We parse token by
% token through the arguments. The
% tokens \verb?r? and \verb?l? cause \cs{cmrkern@r} or \cs{cmrkern@l} to be set to
% \cs{cmidrulekern}. There is no lookahead to see if a width is the
% next token; this strategy is efficient for the plain commands,
% while inefficient for the qualified commands, but more importantly
% it is much easier to program. Tokens \verb?r? and \verb?l? also set
% \cs{cmrswitch} so that if the next token turns out to be
% \marg{wd} then the kerning will be done on the side

% \subsection{Input files into tabulars, and etex}
%
% M.J. Williams (CTT \textit{\cs{noalign} problem with \cs{input} and
% tabular in memoir class}, 28 Aug 2007) reported that using \cs{input} in a
% tabular resulted in errors. His example was:
% \begin{verbatim}
% ...
% \begin{tabular}{c|c} \hline
% 1 & 2 \\ \hline
% \input{data} \hline
% 5 & 6 \\ \hline
% \end{tabular}
% \end{verbatim}
% where \texttt{data.tex} contains the single line (and no newline) \\
% \verb?3 & 4 \\?
%
% Morten H{\o}gholm noted that the problem
% was caused by \Lpack{memoir}'s extension to \cs{input}
% and gave a solution that depends on processing via
% \texttt{etex} rather than \texttt{tex}.
%
% Here's Morten's fix. Quoting, in part:
% \begin{quotation}
% \Lpack{memoir} extends the file loading mechanism by providing
% \cs{AtBeginFile} and \cs{AtEndFile} whose arguments are executed as
% the names indicate. \ldots after inputting a file the storage bins are
% emptied. The problem [in your case] is that this emptying is an
% assignment and so starts a new tabular cell and \cs{hline} is only
% allowed after \verb?\\? or other \cs{hline}s.
%
% \ldots the tabular environment wraps each tabular cell in additional
% groups so one can do an explicit test for which type of group we are in.
% If tested to be in an align group \emph{and} in vertical mode it means
% TeX hasn't found something to start a new cell and
% then \cs{noalign} can be used.

% \section{Floating objects}
%
% The file \file{latex.dtx} only defines a number of tools with
% which floating objects can be defined. This is done in the
% document class. It needs to define the following macros for each
% floating object of type \texttt{TYPE} (e.g., \texttt{TYPE} =
% figure).
%
% \begin{description}
% \item[\texttt{\bslash fps@TYPE}]
% The default placement specifier for floats of type
% \texttt{TYPE}.
%
% \item[\texttt{\bslash ftype@TYPE}]
% The type number for floats of type \texttt{TYPE}. Each
% \texttt{TYPE} has associated a unique positive \texttt
% {TYPE} number, which is a power of two. E.g., figures might
% have type number 1, tables type number 2, programs type
% number 4, etc.
%
% \item[\texttt{\bslash ext@TYPE}]
% The file extension indicating the file on which the contents
% list for float type \texttt{TYPE} is stored. For example,
% \cs{ext@figure} = `lof'.
%
% \item[\texttt{\bslash fnum@TYPE}]
% A macro to generate the figure number for a caption. For
% example, \cs{fnum@TYPE} == `Figure \cs{thefigure}'.
%
% \item[\texttt{\bslash @makecaption}{\meta{num}}{\meta{text}}]
% A macro to make a caption, with \meta{num} the value produced
% by \cs{fnum@...} and \meta{text} the text of the caption. It
% can assume it's in a \cs{parbox} of the appropriate width.
% This will be used for \emph{all} floating objects.
%
% \end{description}
%
% The actual environment that implements a floating object such as
% a figure is defined using the macros \cs{@float} and \cs{end@float},
% which are defined in \file{latex.dtx}.
%
% An environment that implements a single column floating object is
% started with \verb?\@float{TYPE}?\oarg{placement} of type
% \texttt{TYPE} with \meta{placement} as the placement specifier.
% The default value of \meta{PLACEMENT} is defined by \cs{fps@TYPE}.
%
% The environment is ended by \cs{end@float}. E.g., \cs{figure} ==
% \verb?\@float{figure}?, \cs{endfigure} == \cs{end@float}.
%
%
% \subsection{Floats}
%
% To define a float environment, say \Lenv{fenv}, the following macros must be defined:
% \begin{itemize}
% \item \cs{fps@fenv} The default placement specifier (normally \verb?tbp?).
% \item \cs{ftype@fenv} The type number which is an integer and a power of 2.
% \item \cs{ext@fenv} The file extension for the contents list.
% \item \cs{c@fenv} A counter for the environment (for caption numbering).
% \item \cs{fnum@fenv} A macro to generate the caption `number'.
% \item \cs{l@fenv} A macro to produce an entry in a list of\ldots.
% \item \cs{flegtocfenv} A macro to write a \cs{namedlegend} title to a listof file.
% \item \cs{flegfenv} A macro to typeset the name of a \cs{namedlegend}.
% \item \cs{toclevel@fenv} Holding a bookmark level (required if the
% \Lpack{hyperref} package will be used).
% \end{itemize}
%
% \begin{macro}{newflo@tctr}
% A counter for the type number of a new float. Normally
% figures are of type 1, tables type 2, and the next float type is then 4, and so
% on.

% \begin{macro}{\contcaption}
% \cs{contcaption}\marg{text} is a user-level command.
% It is a simplified
% version of the normal \cs{caption} command as it doesn't have to deal
% with numbering or list of \dots entries.
%
% However,
% Brent Lievers\footnote{ (\texttt{lieversb@post.queensu.ca})
% in \ctt{} thread \textit{Figures}, 2003/11/14.} requested that \cs{label}
% should pick up the correct caption number after a \cs{contcaption}.
% \changes{v1.4}{2003/11/22}{Extended \cs{contcaption} (from patch v1.9)}
% \begin{macrocode}

% \end{macro}
%
%
% \begin{macro}{\@@contcaption}
% \begin{macro}{\@contcaption}
% \cs{@contcaption} is the workhorse for the \cs{contcaption} command. In turn,
% it uses the \cs{@makecaption} command (defined in the usual classes)
% to do most of its work. It
% uses the number of the previous \cs{caption} command in the same
% type of float and its implementation includes much of the code
% used in the \LaTeX{} \cs{@caption} command.
%
% First specify \cs{@@contcaption}\marg{type}\marg{title}
% to save some repetitive code.

% \begin{macro}{\legend}
% The macro \cs{legend}\marg{text}is intended

%
% The implementation is similar to the \cs{caption} command but we have
% to eliminate printing of a delimeter.

%
% \begin{macro}{\@legend}
% \cs{@legend}\marg{type}\oarg{short-title}\marg{long-title}
% is the workhorse for the \cs{namedlegend} command. In turn, it calls
% \cs{@makelegend}. It requires two commands to have been defined, namely
% \cs{flegtoctype} and \cs{flegtype}. The command \cs{flegtoctype}\marg{text}
% is responsible for writing a title text to the appropriate listof file.
% \cs{flegtype} is responsible for typeseting the name of the legend.

% \subsubsection{Bilingual captions}
%
% The bilingual caption commands all use internal grouping so
% that any changes are kept local. This has the unfortunate side-effect
% that any \cs{label} command must be within the grouping otherwise the
% wrong number is picked up. To make the coding, if not necessarily the
% use, of the commands simpler, I have not used the traditional style
% of square brackets for optional caption text arguments. Instead, empty
% `required' arguments are used as the implementation means.

% \subsection{Title referencing}
%
% This is based on DA's \Lpack{titleref} package~\cite{TITLEREF}.
% The following
% remarks are taken from that package.
%
%
% Titles for numbered sectioning units and for floats with captions are
% the same as the respective TOC, LOF, or LOT entry (even when no TOC is
% printed). When a short title is provided (\verb?\section[short]{long}?)
% it will be used for the \cs{titleref}. This is especially useful for
% figure captions. Unnumbered sections take their title reference from
% the printed title. Beware! This turns the title into a moving argument
% when it normally is not, and will cause weird errors if there are
% `fragile' commands present.
%
% Enumerated lists do not have titles and simply inherit the title of
% their section.
%
% The format of the title reference is controlled by the command
% \cs{theTitleReference}, which can be redefined with \cs{renewcommand}.
% It takes two parameters: the number and the title. The number is
% just the regular \cs{ref} and it is WRONG in unnumbered sections.
% Beware! The default definition is the unadorned title. You could
% do, for example, \\
% \verb?\renewcommand{\theTitleReference}[2]{#1\ \emph{#2}}?.
%
% The title of the current section is also available without \cs{label}:
% Use the command \cs{currenttitle} to generate a \cs{titleref} to the current
% section. If you have redefined \cs{theTitleReference} to print the number
% with the title, be aware that the two may not correspond: In a numbered
% list the number will show the current item but the title will show the
% current section, but in an unnumbered section the number will show
% some previous section number.
%
% The big problem with the \verb?[usetoc]? method is that \cs{titleref} will
% not refer to a \cs{label} which was given in the title or caption itself;
% the label must be placed after the sectioning command or the caption.
% If you make a title-reference to a label given in a title, you will get
% a warning message.

% \section{Table of Contents, etc.}
%
% A \cs{section} command writes a
% \verb?\contentsline{section}?\marg{title}\marg{page} command
% on the \file{.toc} file, where \meta{title} contains the

% sections are being numbered, then \meta{title} will be of the
% form \cs{numberline}\marg{num}\marg{heading} where
% \meta{num} is the number produced by \cs{thesection}. Other
% sectioning commands work similarly.
%
% A \cs{caption} command in a `figure' environment writes \\

%
% It is apparent that users want to do at least two things that are not
% readily provided by the standard classes: (a) change the appearance
% of the Table of Contents, etc., headings, and (b) create new List of\ldots.
% This class provides a means of creating new Lists whose headings are
% parameterized, thereby killing two birds with one stone.
%
% In the standard classes the tables of contents, figures etc. are always
% set in single-column style. In this class you can choose one- or two-column
% ToCs, etc.

%
% Now for the trickier bits regarding the typesetting of the ToC
% entries.
%
% A \file{.toc} (also \file{.lof} and \file{.lot}) file consists
% of a list of \\
% \cs{contentsline}\marg{kind}\marg{title}\marg{page} \\
% commands, where \meta{kind} is the kind of heading (e.g., \texttt{part} or
% \texttt{section} or \texttt{figure}), \meta{title} is the title text
% (including the number),
% and \meta{page} is the page number. The entries are inserted into the
% file by calling the \\
% \cs{addcontentsline}\marg{file}\marg{kind}\marg{title} \\
% command, where \meta{file} is the file extension (e.g., \texttt{toc}, \texttt{lot})
% and the other arguments are the same as for the \cs{contentsline}
% command. (Arbitrary stuff may also be put into the file via the
% \cs{addtocontents}\marg{file}\marg{text} command).
% The typesetting of the \cs{contentsline} entries is performed by
% commands of the form \cs{l@kind}. The sectioning and captioning commands
% call \cs{addcontentsline} to insert their titles into the \file{.toc}
% etc., files.
%
% For the purposes at hand it is generally impossible to treat
% the typesetting
% of a title and its number separately, as both are bundled into the
% \meta{title} argument within \cs{contentsline}. They could be handled
% separately if the \cs{contentsline} command was suitably modified. If
% this was done, then the \cs{addtocontentsline} command would also need
% to be changed which would then require the sectioning and captioning
% commands to be modified as well. This is certainly possible, but would
% cause problems if any other package also modified the sectioning or
% captioning commands, and there are several packages which do this.
%
% I provide modified versions of the \cs{l@kind} commands.
% Essentially, my new definitions

% and the page number is ignored.

%
% There was a discussion \textit{widow handling?} on CTT in
% May 2006. \texttt{ivowel@gmail.com} wrote
% \begin{quote}
% in experimenting with raggedbottom, widowpenalty, and clubpenalty,
% I think that I have not found a solution that strikes me as
% particularly desirable. I think what I would really like is that
% widows (i.e., left-over single lines that begin on the following
% page) are resolved not by pushing one extra line from the same
% paragraph also onto the next page, but by stretching the
% \cs{textheight} to allow this one extra at the bottom of the
% same page.
% \end{quote}
% Donald Arseneau, as he so often does, came up with a solution he
% termed \cs{sloppybottom}. Here is a generalised version.
%
% \begin{macro}{\sloppybottom}
% \cs{sloppybottom} allows an extra line on a page to save a widow.
% You must increase the \cs{topskip} (by 60 percent is reasonable) and this
% will push the text lower on the page. Run \cs{checkandfixthelayout}
% after the change. For example:
% \begin{verbatim}
% \setlength{\topskip}{1.6\topskip}
% \checkandfixthelayout
% \sloppybottom
% ...

% \subsection{Marginpars}
%
% A \cs{marginpar} is a kind of floating object --- you can't control
% exactly where it will go. There is one problem with the kernel
% definition of \cs{marginpar} in that sometimes a \cs{marginpar} may
% end up on the wrong side of the page. The following is an attempt
% to fix that using the odd/even page check provided as part of
% the class.
%
% \begin{macro}{\@addmarginpar}
% The part of the code for \cs{marginpar} that deals with deciding which
% side of the page it should be printed on is \cs{@addmarginpar}, buried
% away in the kernel's \texttt{output} routine. A couple of minor changes are made
% to the kernel code. The first is at the beginning where I have added
% the \cs{checkoddpage} page checking code.
% \begin{macrocode}
\def\@addmarginpar{%

% The next line, reading \\

% replace it with my code, and then continue with the kernel.

% for this came from a CTT thread, \textit{whitespace after my command},
% 2006/11/30 and earlier. In email to me on 2006/11/30 he said:
% \begin{quotation}
% For \Lpack{memoir} \cs{sidebar}, it seems the rules are expanding
% to fill the space for the sidebar, so here is my suggested change
% to \cs{sidecontents}.
%
% It occurs to me that a separate \cs{sidetsep} (or \cs{sidetopsep})
% would be more valuable than having an explicit 1\cs{onelineskip}.
%
% I grouped common code into two macros, and altered \cs{sidebarform} too.
% \end{quotation}
%
% Since then we have been going back and forth, with the result that
% practically all the complex code is Donald's.

% Florence Henry (\texttt{florence.henry@obspm.fr}) in the thread

% out that \texttt{itemize} in a \cs{sidebar} could overflow. DA gave the
% solution hint.
%
% DA says that having stacked insertions position properly is difficult.
% Here he uses the size of the strut to regulate both the height and the
% depth of each insertion (much as for footnotes). The following is his
% code and commentary.

% The footnote mechanism of \LaTeX{} calls the macro \cs{@makefntext}

% of the footnote. The macro \cs{@makefntext} is called when
% effectively inside a \cs{parbox} of width \cs{columnwidth} (i.e.,
% with \cs{hsize} = \cs{columnwidth}).

% flushright against the footnote.
%
% The standard classes use a simpler macro, in which the
% footnote text is set like an ordinary text paragraph, with no
% indentation except on the first line of a paragraph, and the
% first line of the footnote. Thus, all the macro must do is set
% \cs{parindent} to the appropriate value for succeeding paragraphs
% and put the proper indentation before the mark.

% \changes{v1.61803}{2008/01/30}{Put \cs{@makecol} and associated code

% do.
%
% Before v1.61803 \cs{@makecol} got (re)defined at several points in the

% \section{Trimming marks}
%
% The \Lopt{showtrims} options prints trimming marks at the corners
% of the logical page. The code for this comes from ideas gleaned
% from Martin Schr\"{o}der's \Lpack{everyshi} package~\cite{EVERYSHI}
% and Melchior Franz's \Lpack{crop} package~\cite{CROP}.
% The implementation and any errors are mine.
%
% The implementation up to October 2002 was limited to putting a cross
% at the page corners. The manual directed users to the \Lpack{crop}
% packge if they wanted anything more. In October 2002 the implementation
% was substantially extended. The background to this is below.
%
% Before the release of version 1.7 of \Lpack{crop} in May 2002 its
% author asked me to make some changes to \Lpack{memoir} that would be
% helpful to him, and I did so. Later he told me that the changes were
% unnecessary and I reverted to the original \Lpack{memoir} code.
%
% On 2002/10/06 Peter Heslin (\url{peter.heslin@ucd.ie}) started a
% thread on \url{comp.text.tex} titled `Incompatibility of memoir.cls
% and crop.sty' in which he said that \Lpack{memoir} and \Lpack{crop}
% did not seem to work together. The following are some snippets from
% that thread, identified by the various proponents.
% \begin{description}
% \item[crop] Ah, yes. It cannot work with all those \cs{settrims} etc.
% crop.sty does only respect \verb?\stock{width,height}?,
% but none of the other memoir specific trim marks stuff \ldots
%
% \item[crop] \ldots I'm not a memoir expert. crop.sty respects all the
% usual LaTeX paper dimensions and simply puts the marks around the
% page. It works with all standard classes and the KOMA classes. memoir
% seems to do things completely differently \ldots
%
% Sorry, but I'm afraid I have to pass the problem to the memoir
% author. \ldots
%
% \item[memoir] I will try and take a look at the problem but I'm
% not a crop expert --- I've never used it. However it seems odd to
% me that crop doesn't work with memoir. Memoir provides a different
% interface for specifying the page layout but then translates everything
% to the standard length variables. \ldots
%
% \item[crop] You've just taken code from it \verb?...:->?
%
% crop doesn't have its own idea at all. It just uses that of DEK
% and LaTeX, which says, that the reference point of the output box
% in the output routine is assumed 1 inch to the left [later corrected
% to right] and 1 inch down
% from the upper left (virtual) paper corner.
%
% \item[crop] With other words: crop changes \cs{hoffset} and \cs{voffset},
% in order to center the logical (virtual) page on the physical sheet
% of paper, in the middle of the crop marks. The length macros
% \cs{evensidemargin} and \cs{oddsidemargin} are unchanged and refer still
% to the logical page (modulo 1 inch).
%
% The memoir class, in contrast (mis)uses the LaTeX margins
% \cs{even(odd)sidemargin} for that purpose.
%
% Thus, the meaning of \cs{even(odd)sidemargin} is different
% in both packages.
% \end{description}
%
% Given all the above I concluded that \Lpack{crop} would remain
% as it was, and that in order to satisfy Peter Heslin I would have
% to extend the trimming marks. The following was originally limited to
% extensions
% asked for by Peter Heslin.

% \end{macrocode}
% Processing a line inside a \texttt{verbatim} or \texttt{verbatim*}

% Ending the line means that we have to begin a new paragraph.
% We use \cs{par} for this purpose. Note that \cs{par}

% do appear in the output.

%
% \begin{macro}{\verbatim@finish}
% As a default, \cs{verbatim@finish} processes the remaining
% characters.
% When this macro is called we are facing the following problem:
% when the \verb?\end{verbatim}?
% command is encountered \cs{verbatim@processline} is called
% to process the characters preceding the command on the same
% line. If there are none, an empty line would be output if we
% did not check for this case.
%
% If the line is empty \verb?\the\verbatim@line? expands to
% nothing. To test this we use a trick similar to that on p.\ 376
% of the \TeX{}book, but with \verb?$?\ldots\verb?|$? instead of
% the \verb?!? tokens. These \verb?$? tokens can never have the same
% category code as a \verb?$? token that might possibly appear in the
% token register \cs{verbatim@line}, as such a token will always have
% been read with category code $12$ (other).
% Note that \cs{ifcat} expands the following tokens so that
% \verb?\the\verbatim@line? is replaced by the accumulated
% characters

%
% \subsubsection{The \texttt{verbatim} and \texttt{verbatim*} environments}
%
% \begin{macro}{\verbatim@font}
% We start by defining the macro \cs{verbatim@font} that is
% to select the font and to set font-dependent parameters.
% Then we go through \cs{verbatim@nolig@list} to avoid
% certain ligatures.
% \cs{verbatim@nolig@list} is a macro defined in the \LaTeXe{} kernel
% to expand to
% \begin{verbatim}
% \do\`\do\<\do\>\do\,\do\'\do\-
% \end{verbatim}
% All the characters in this list can be part of a ligature in some
% font or other.
%
% PW. This is the original version which I'm going to replace.
% \begin{verbatim}
% \def\verbatim@font{\normalfont\ttfamily
% \hyphenchar\font\m@ne
% \let\do\do@noligs
% \verbatim@nolig@list}
% \end{verbatim}
% \end{macro}
%
% \begin{macro}{\setverbatimfont}
% \begin{macro}{\m@mverbfont}
% \begin{macro}{\verbatim@font}
% User level handle for changing the font used for verbatim text.
% \begin{macrocode}
\newcommand{\setverbatimfont}[1]{\def\m@mverbfont{#1}}
\setverbatimfont{\normalfont\ttfamily}
\def\verbatim@font{\m@mverbfont
\hyphenchar\font\m@ne
\let\do\do@noligs
\verbatim@nolig@list}
% \end{macrocode}
% \end{macro}
% \end{macro}
% \end{macro}
%
%
% \begin{macro}{\@verbatim}
% The macro \cs{@verbatim} sets up things properly.
% First of all, the tokens of the \cs{every@verbatim} hook
% are inserted.
% Then a \texttt{trivlist} environment is started and its first
% \cs{item} command inserted.
% Each line of the \texttt{verbatim} or \texttt{verbatim*}
% environment will be treated as a separate paragraph.
% \begin{macrocode}
\def\@verbatim{\the\every@verbatim
\trivlist \item \relax
% \end{macrocode}
% The following extra vertical space is for compatibility with the
% \LaTeX kernel: otherwise, using the \Lpack{verbatim} package changes
% the vertical spacing of a \texttt{verbatim} environment nested within a
% \texttt{quote} environment.
% \begin{macrocode}
\if@minipage\else\vskip\parskip\fi
% \end{macrocode}
% The paragraph parameters are set appropriately:
% the penalty at the beginning of the environment,
% left and right margins, paragraph indentation, the glue to
% fill the last line, and the vertical space between paragraphs.
% The latter space has to be zero since we do not want to add
% extra space between lines.
% \begin{macrocode}
\@beginparpenalty \predisplaypenalty
\leftskip\@totalleftmargin\rightskip\z@
\parindent\z@\parfillskip\@flushglue\parskip\z@
% \end{macrocode}
% There's one point to make here:
% the \texttt{list} environment uses \TeX's \cs{parshape}
% primitive to get a special indentation for the first line
% of the list.
% If the list begins with a \texttt{verbatim} environment
% this \cs{parshape} is still in effect.
% Therefore we have to reset this internal parameter explicitly.
% We could do this by assigning $0$ to \cs{parshape}.
% However, there is a simpler way to achieve this:
% we simply tell \TeX{} to start a new paragraph.
% As is explained on p.~103 of the \TeX{}book, this resets
% \cs{parshape} to zero.
% \begin{macrocode}
\@@par
% \end{macrocode}
% We now ensure that \cs{par} has the correct definition,
% namely to force \TeX{} into horizontal mode
% and to include an empty box.
% This is to ensure that empty lines do appear in the output.
% Afterwards, we insert the \cs{interlinepenalty} since \TeX{}
% does not add a penalty between paragraphs (here: lines)
% by its own initiative. Otherwise a \texttt{verbatim} environment
% could be broken across pages even if a \cs{samepage}
% declaration were present.
%
% However, in a top-aligned minipage, this will result in an extra
% empty line added at the top. Therefore, a slightly more
% complicated construct is necessary.
% One of the important things here is the inclusion of
% \cs{leavevmode} as the first macro in the first line, for example,
% a blank verbatim line is the first thing in a list item.
% \begin{macrocode}
\def\par{%
\if@tempswa
\leavevmode\null\@@par\penalty\interlinepenalty
\else
\@tempswatrue
\ifhmode\@@par\penalty\interlinepenalty\fi
\fi}%
% \end{macrocode}
% But to avoid an error message when the environment
% doesn't contain any text, we redefine \cs{@noitemerr}
% which will in this case be called by \cs{endtrivlist}.
% \begin{macrocode}
\def\@noitemerr{\@warning{No verbatim text}}%
% \end{macrocode}
% Now we call \cs{obeylines} to make the end of line character
% active,
% \begin{macrocode}
\obeylines
% \end{macrocode}
% change the category code of all special characters,
% to $12$ (other).
% \begin{macrocode}
\let\do\@makeother \dospecials
% \end{macrocode}
% and switch to the font to be used.
% \begin{macrocode}
\verbatim@font
% \end{macrocode}
% To avoid a breakpoint after the labels box, we remove the penalty
% put there by the list macros: another use of \cs{unpenalty}!
% \begin{macrocode}
\everypar \expandafter{\the\everypar \unpenalty}%
% \end{macrocode}
% PW added next code at end of \cs{@verbatim}.
% \begin{macrocode}
\wrapright\the\afterevery@verbatim}
% \end{macrocode}
% \end{macro}
%
%
% \begin{macro}{\verbatim}
% \begin{macro}{\verbatim*}
% Now we define the toplevel macros.
% \cs{verbatim} is slightly changed:
% after setting up things properly it calls
% \cs{verbatim@start}.
% This is done inside a group, so that \cs{verbatim} can be used
% directly, without \cs{begin}.
%
% PW. The following is the original code, but I want a version of
% \texttt{verbatim} that recognises TABs.
% \begin{verbatim}

%
%
% \begin{macro}{\endverbatim}
% \begin{macro}{\endverbatim*}
% To end the \texttt{verbatim} and \texttt{verbatim*}
% environments it is only necessary to finish the
% \texttt{trivlist} environment started in \cs{@verbatim} and

%
% For abnormal \cs{parskip}s the NTG class included the following, but I'm
% not sure if it is relevant here, but if it is just how it should be included.
% \begin{verbatim}

% \providecommand*{\verbatim}{%
% \topsep=-0.5\parskip
% \@verbatim
% \frenchspacing\@vobeyspaces \@xverbatim}
% \end{verbatim}
%
%
% \subsubsection{The \texttt{comment} environment}
%
% The \cs{comment} macro is similar to \cs{verbatim*}.
% However, we do not need to switch fonts or set special
% formatting parameters such as \cs{parindent} or \cs{parskip}.
% We need only set the category code of all special characters
% to $12$ (other) and that of \verb?^^M? (the end of line character)
% to $13$ (active).
% The latter is needed for macro parameter delimiter matching in
% the internal macros defined below.
% In contrast to the default definitions used by the
% \cs{verbatim} and \cs{verbatim*} macros,
% we define \cs{verbatim@addtoline} to throw away its argument
% and \cs{verbatim@processline}, \cs{verbatim@startline},
% and \cs{verbatim@finish} to act as no-ops.
% Then we call \cs{verbatim@}.
% But the first thing we do is to call \cs{@bsphack} so that
% this environment has no influence whatsoever upon the spacing.
%
% PW: This is the original code for the \texttt{comment} environment,
% which I'm going to change.
% \begin{verbatim}
% \def\comment{\@bsphack
% \let\do\@makeother\dospecials\catcode`\^^M\active
% \let\verbatim@startline\relax
% \let\verbatim@addtoline\@gobble
% \let\verbatim@processline\relax
% \let\verbatim@finish\relax
% \verbatim@}
% \end{verbatim}
% \cs{endcomment} is very simple: it only calls
% \cs{@esphack} to take care of the spacing.
% The \cs{end} macro closes the group and therefore takes care
% of restoring everything we changed.
% \begin{verbatim}
% \let\endcomment=\@esphack
% \end{verbatim}
%
% PW: The remainder of this section is my code.
%
% \begin{macro}{\setupcomment}
% \cs{setupcomment} does all the \cs{let}s in the original \cs{comment} code.
% \begin{macrocode}
\newcommand{\setupcomment}{%
\let\do\@makeother\dospecials\catcode`\^^M\active
\let\verbatim@startline\relax
\let\verbatim@addtoline\@gobble
\let\verbatim@processline\relax
\let\verbatim@finish\relax}
% \end{macrocode}
% \end{macro}
%
% The macros below do no checking to see if something has (not) been defined
% previously. It's `user beware' time.
%
% \begin{macro}{\newcomment}
% \cs{newcomment}\marg{name} creates a new comment environment called
% \meta{name}. This is a generalisation of the original comment code.
% \begin{macrocode}
\newcommand{\newcomment}[1]{%
\expandafter\def\csname #1\endcsname{\@bsphack\setupcomment\verbatim@}%
\expandafter\let\csname end#1\endcsname=\@esphack}
% \end{macrocode}
% \end{macro}
%
% \begin{macro}{\commentsoff}
% \cs{commentsoff}\marg{name} switches off the \meta{name} comment
% environment by defining the relevent macros to do nothing.
% \begin{macrocode}
\newcommand{\commentsoff}[1]{%
\expandafter\def\csname #1\endcsname{}%
\expandafter\def\csname end#1\endcsname{}}
% \end{macrocode}
% \end{macro}
%
% \begin{macro}{\commentson}
% \cs{commentson}\marg{name} switches on the \meta{name} comment
% environment. It has to do the same things as \cs{newcomment} does,
% so let \cs{newcomment} do the work.
% \begin{macrocode}
\newcommand{\commentson}[1]{\newcomment{#1}}
% \end{macrocode}
% \end{macro}
%
% We had better supply the \texttt{comment} environment, as promised.
% \begin{macrocode}
\newcomment{comment}
% \end{macrocode}
%
% PW: That is the end of my changes and extensions to the original
% \texttt{comment} environment code.
%
%
% \subsubsection{The main loop}
%
% Here comes the tricky part:
% During the definition of the macros we need to use the special
% characters \verb?\?, \verb?{?, and \verb?}? not only with their
% normal category codes,
% but also with category code $12$ (other).
% We achieve this by the following trick:
% first we tell \TeX{} that \verb?\?, \verb?{?, and \verb?}?
% are the lowercase versions of \verb?!?, \verb?[?, and \verb?]?.
% Then we replace every occurrence of \verb?\?, \verb?{?, and \verb?}?
% that should be read with category code $12$ by \verb?!?, \verb?[?,
% and \verb?]?, respectively,
% and give the whole list of tokens to \cs{lowercase},
% knowing that category codes are not altered by this primitive!
%
% But first we have ensure that
% \verb?!?, \verb?[?, and \verb?]? themselves have
% the correct category code!
% To allow special settings of these codes we hide their setting in
% the macro \cs{vrb@catcodes}. If it is already defined our new
% definition is skipped.
% \begin{macrocode}
\@ifundefined{vrb@catcodes}%
{\def\vrb@catcodes{%
\catcode`\!12\catcode`\[12\catcode`\]12}}{}
% \end{macrocode}
% This trick allows us to use this code for applications where other
% category codes are in effect.
%
% We start a group to keep the category code changes local.
% \begin{macrocode}
\begingroup
\vrb@catcodes
\lccode`\!=`\\ \lccode`\[=`\{ \lccode`\]=`\}
% \end{macrocode}
% We also need the end-of-line character \verb?^^M?,
% as an active character.
% If we were to simply write \verb?\catcode`\^^M=\active?
% then we would get an unwanted active end of line character
% at the end of every line of the following macro definitions.
% Therefore we use the same trick as above:
% we write a tilde \verb?~? instead of \verb?^^M? and
% pretend that the
% latter is the lowercase variant of the former.
% Thus we have to ensure now that the tilde character has
% category code $13$ (active).
% \begin{macrocode}
\catcode`\~=\active \lccode`\~=`\^^M
% \end{macrocode}
% The use of the \cs{lowercase} primitive leads to one problem:
% the uppercase character `\texttt{C}' needs to be used in the
% code below and its case must be preserved.
% So we add the command:
% \begin{macrocode}
\lccode`\C=`\C
% \end{macrocode}
% Now we start the token list passed to \cs{lowercase}.
% We use the following little trick (proposed by Bernd Raichle):
% The very first token in the token list we give to \cs{lowercase} is
% the \cs{endgroup} primitive. This means that it is processed by
% \TeX{} immediately after \cs{lowercase} has finished its operation,
% thus ending the group started by \cs{begingroup} above. This avoids
% the global definition of all macros.
% \begin{macrocode}
\lowercase{\endgroup
% \end{macrocode}
% \begin{macro}{\verbatim@start}
% The purpose of \cs{verbatim@start} is to check whether there
% are any characters on the same line as the \verb?\begin{verbatim}?
% and to pretend that they were on a line by themselves.
% On the other hand, if there are no characters remaining
% on the current line we shall just find an end of line character.
% \cs{verbatim@start} performs its task by first grabbing the
% following character (its argument).
% This argument is then compared to an active \verb?^^M?,
% the end of line character.
% \begin{macrocode}
\def\verbatim@start#1{%
\verbatim@startline
\if\noexpand#1\noexpand~%
% \end{macrocode}
% If this is true we transfer control to \cs{verbatim@}
% to process the next line. We use
% \cs{next} as the macro which will continue the work.
% \begin{macrocode}
\let\next\verbatim@
% \end{macrocode}
% Otherwise, we define \cs{next} to expand to a call
% to \cs{verbatim@} followed by the character just
% read so that it is reinserted into the text.
% This means that those characters remaining on this line
% are handled as if they formed a line by themselves.
% \begin{macrocode}
\else \def\next{\verbatim@#1}\fi
% \end{macrocode}
% Finally we call \cs{next}.
% \begin{macrocode}
\next}%
% \end{macrocode}
% \end{macro}
%
% \begin{macro}{\verbatim@}
% The three macros \cs{verbatim@}, \cs{verbatim@@},
% and \cs{verbatim@@@} form the ``main loop'' of the
% \texttt{verbatim} environment.
% The purpose of \cs{verbatim@} is to read exactly one line
% of input.
% \cs{verbatim@@} and \cs{verbatim@@@} work together to
% find out whether the four characters
% \cs{end} (all with category code $12$ (other)) occur in that
% line.
% If so, \cs{verbatim@@@} will call
% \cs{verbatim@test} to check whether this \cs{end} is
% part of \verb?\end{verbatim}? and will terminate the environment
% if this is the case.
% Otherwise we continue as if nothing had happened.
% So let's have a look at the definition of \cs{verbatim@}:
% \begin{macrocode}
\def\verbatim@#1~{\verbatim@@#1!end\@nil}%
% \end{macrocode}
% Note that the \verb?!? character will have been replaced by a
% \verb?\? with category code $12$ (other) by the \cs{lowercase}
% primitive governing this code before the definition of this
% macro actually takes place.
% That means that
% it takes the line, puts \cs{end} (four character tokens)
% and \cs{@nil} (one control sequence token) as a
% delimiter behind it, and
% then calls \cs{verbatim@@}.
% \end{macro}
%
% \begin{macro}{\verbatim@@}
% \cs{verbatim@@} takes everything up to the next occurrence of
% the four characters \cs{end} as its argument.
% \begin{macrocode}
\def\verbatim@@#1!end{%
% \end{macrocode}
% That means: if they do not occur in the original line, then
% argument \verb?#1? is the
% whole input line, and \cs{@nil} is the next token
% to be processed.
% However, if the four characters \cs{end} are part of the
% original line, then
% \verb?#1? consists of the characters in front of \cs{end},
% and the next token is the following character (always remember
% that the line was lengthened by five tokens).
% Whatever \verb?#1? may be, it is verbatim text,
% so \verb?#1? is added to the line currently built.
% \begin{macrocode}
\verbatim@addtoline{#1}%
% \end{macrocode}
% The next token in the input stream
% is of special interest to us.
% Therefore \cs{futurelet} defines \cs{next} to be equal
% to it before calling \cs{verbatim@@@}.
% \begin{macrocode}
\futurelet\next\verbatim@@@}%
% \end{macrocode}
% \end{macro}
%
% \begin{macro}{\verbatim@@@}
% \cs{verbatim@@@} will now read the rest of the tokens on
% the current line,
% up to the final \cs{@nil} token.
% \begin{macrocode}
\def\verbatim@@@#1\@nil{%
% \end{macrocode}
% If the first of the above two cases occurred, i.e.\ no
% \cs{end} characters were on that line, \verb?#1? is empty
% and \cs{next} is equal to \cs{@nil}.
% This is easily checked.
% \begin{macrocode}
\ifx\next\@nil
% \end{macrocode}
% If so, this was a simple line.
% We finish it by processing the line we accumulated so far.
% Then we prepare to read the next line.
% \begin{macrocode}
\verbatim@processline
\verbatim@startline
\let\next\verbatim@
% \end{macrocode}
% Otherwise we have to check what follows these \cs{end}
% tokens.
% \begin{macrocode}
\else
% \end{macrocode}
% Before we continue, it's a good idea to stop for a moment
% and remember where we are:
% We have just read the four character tokens \cs{end}
% and must now check whether the name of the environment (surrounded
% by braces) follows.
% To this end we define a macro called \cs{@tempa}
% that reads exactly one character and decides what to do next.
% This macro should do the following: skip spaces until
% it encounters either a left brace or the end of the line.
% But it is important to remember which characters are skipped.
% The \cs{end}\meta{optional spaces}\verb?{? characters
% may be part of the verbatim text, i.e.\ these characters
% must be printed.
%
% Assume for example that the current line contains
% \begin{verbatim*}
% \end {AVeryLongEnvironmentName}
%\end{verbatim*}
% As we shall soon see, the scanning mechanism implemented here
% will not find out that this is text to be printed until
% it has read the right brace.
% Therefore we need a way to accumulate the characters read
% so that we can reinsert them if necessary.
% The token register \cs{@temptokena} is used for this purpose.
%
% Before we do this we have to get rid of the superfluous
% \cs{end} tokens at the end of the line.
% To this end we define a temporary macro whose argument
% is delimited by \verb?\end\@nil? (four character tokens
% and one control sequence token) to be used below
% on the rest of the line, after appending a \cs{@nil} token to it.
% (Note that this token can never appear in \verb?#1?.)
% We use the following definition of
% \cs{@tempa} to get the rest of the line (after the first
% \cs{end}).
% \begin{macrocode}
\def\@tempa##1!end\@nil{##1}%
% \end{macrocode}
% We mentioned already that we use token register
% \cs{@temptokena}
% to remember the characters we skip, in case we need them again.
% We initialize this with the \cs{end} we have thrown away
% in the call to \cs{@tempa}.
% \begin{macrocode}
\@temptokena{!end}%
% \end{macrocode}
% We shall now call \cs{verbatim@test}
% to process the characters
% remaining on the current line.
% But wait a moment: we cannot simply call this macro
% since we have already read the whole line.
% Therefore we have to first expand the macro \cs{@tempa} to insert
% them again after the \cs{verbatim@test} token.
% A \verb?^^M? character is appended to denote the end of the line.
% (Remember that this character comes disguised as a tilde.)
% \begin{macrocode}
\def\next{\expandafter\verbatim@test\@tempa#1\@nil~}%
% \end{macrocode}
% That's almost all, but we still have to
% now call \cs{next} to do the work.
% \begin{macrocode}
\fi \next}%
% \end{macrocode}
% \end{macro}
%
%
% \begin{macro}{\verbatim@test}
% We define \cs{verbatim@test} to investigate every token
% in turn.
% \begin{macrocode}
\def\verbatim@test#1{%
% \end{macrocode}
% First of all we set \cs{next} equal to \cs{verbatim@test}
% in case this macro must call itself recursively in order to
% skip spaces.
% \begin{macrocode}
\let\next\verbatim@test
% \end{macrocode}
% We have to distinguish four cases:
% \begin{enumerate}
% \item The next token is a \verb?^^M?, i.e.\ we reached
% the end of the line. That means that nothing
% special was found.
% Note that we use \cs{if} for the following
% comparisons so that the category code of the
% characters is irrelevant.
% \begin{macrocode}
\if\noexpand#1\noexpand~%
% \end{macrocode}
% We add the characters accumulated in token register
% \cs{@temptokena} to the current line. Since
% \cs{verbatim@addtoline} does not expand its argument,
% we have to do the expansion at this point. Then we
% \cs{let} \cs{next} equal to \cs{verbatim@}
% to prepare to read the next line.
% \begin{macrocode}
\expandafter\verbatim@addtoline
\expandafter{\the\@temptokena}%
\verbatim@processline
\verbatim@startline
\let\next\verbatim@
% \end{macrocode}
% \item A space character follows.
% This is allowed, so we add it to \cs{@temptokena}
% and continue.
% \begin{macrocode}
\else \if\noexpand#1
\@temptokena\expandafter{\the\@temptokena#1}%
% \end{macrocode}
% \item An open brace follows.
% This is the most interesting case.
% We must now collect characters until we read the closing
% brace and check whether they form the environment name.
% This will be done by \cs{verbatim@testend}, so here
% we let \cs{next} equal this macro.
% Again we will process the rest of the line, character
% by character.
% The characters forming the name of the environment will
% be accumulated in \cs{@tempc}.
% We initialize this macro to expand to nothing.
% \begin{macrocode}
\else \if\noexpand#1\noexpand[%

% \end{macro}
%
% \begin{macro}{\verbatim@testend}
% \cs{verbatim@testend} is called when

% Its task is to scan everything up to the next \verb?}?
% and to call \cs{verbatim@@testend}.
% If no \verb?}? is found it must reinsert the characters it read
% and return to \cs{verbatim@}.
% The following definition is similar to that of
% \cs{verbatim@test}:
% it takes the next character and decides what to do.
% \begin{macrocode}
\def\verbatim@testend#1{%
% \end{macrocode}
% Again, we have four cases:
% \begin{enumerate}
% \item \verb?^^M?: As no \verb?}? is found in the current line,
% add the characters to the buffer. To avoid a
% complicated construction for expanding
% \cs{@temptokena}
% and \cs{@tempc} we do it in two steps. Then we

% next line.
% \begin{macrocode}

\let\next\verbatim@@testend
% \end{macrocode}
% \item \verb?\?: This character must not occur in the name of
% an environment. Thus we stop collecting characters.
% In principle, the same argument would apply to other
% characters as well, e.g., \verb?{?.
% However, \verb?\? is a special case, since it may be
% the first character of \cs{end}. This means that
% we have to look again for
% \cs{end}\marg{environment name}
% Note that we prefixed the \verb?!? by a \cs{noexpand}
% primitive, to protect ourselves against it being an
% active character.
% \begin{macrocode}

% \end{macrocode}
% \item Any other character: collect it and continue.

% \begin{macrocode}

{\@tempc#1}\fi\fi\fi
% \end{macrocode}
% \end{enumerate}
% As before, the macro ends by calling itself, to
% process the next character if appropriate.
% \begin{macrocode}
\next}%
% \end{macrocode}
% \end{macro}
%
% \begin{macro}{\verbatim@@testend}
% Unlike the previous macros \cs{verbatim@@testend} is simple:
% it has only to check if the \cs{end}\marg{...}
% matches the corresponding \cs{begin}\marg{...}
% \begin{macrocode}
\def\verbatim@@testend{%
% \end{macrocode}
% We use \cs{next} again to define the things that are
% to be done.
% Remember that the name of the current environment is
% held in \cs{@currenvir}, the characters accumulated
% by \cs{verbatim@testend} are in \cs{@tempc}.
% So we simply compare these and prepare to execute
% \cs{end}\marg{current environment}
% macro if they match.
% Before we do this we call \cs{verbatim@finish} to process
% the last line.
% We define \cs{next} via \cs{edef} so that
% \cs{@currenvir} is replaced by its expansion.
% Therefore we need \cs{noexpand} to inhibit the expansion
% of \cs{end} at this point.
% \begin{macrocode}
\ifx\@tempc\@currenvir
\verbatim@finish
\edef\next{\noexpand\end{\@currenvir}%
% \end{macrocode}
% Without this trick the \cs{end} command would not be able
% to correctly check whether its argument matches the name of
% the current environment and you'd get an
% interesting \LaTeX{} error message such as:
% \begin{verbatim}
%! \begin{verbatim*} ended by \end{verbatim*}.
%\end{verbatim}
% But what do we do with the rest of the characters, those
% that remain on that line?
% We call \cs{verbatim@rescan} to take care of that.
% Its first argument is the name of the environment just
% ended, in case we need it again.
% \cs{verbatim@rescan} takes the list of characters to be
% reprocessed as its second argument.
% (This token list was inserted after the current macro
% by \cs{verbatim@@@}.)
% Since we are still in an \cs{edef} we protect it
% by means of\cs{noexpand}.
% \begin{macrocode}
\noexpand\verbatim@rescan{\@currenvir}}%
% \end{macrocode}
% If the names do not match, we reinsert everything read up
% to now and prepare to call \cs{verbatim@} to process
% the rest of the line.
% \begin{macrocode}
\else
\expandafter\verbatim@addtoline
\expandafter{\the\@temptokena[}%
\expandafter\verbatim@addtoline
\expandafter{\@tempc]}%
\let\next\verbatim@
\fi
% \end{macrocode}
% Finally we call \cs{next}.
% \begin{macrocode}
\next}%
% \end{macrocode}
% \end{macro}
%
% \begin{macro}{\verbatim@rescan}
% In principle \cs{verbatim@rescan} could be used to
% analyse the characters remaining after the \verb?\end{...}?
% command and pretend that these were read
% ``properly'', assuming ``standard'' category codes are in
% force.\footnote{Remember that they were all read with
% category codes $11$ (letter) and $12$ (other) so
% that control sequences are not recognized as such.}
% But this is not always possible (when there are unmatched
% curly braces in the rest of the line).
% Besides, we think that this is not worth the effort:
% After a \texttt{verbatim} or \texttt{verbatim*} environment
% a new line in the output is begun anyway,
% and an \verb?\end{comment}? can easily be put on a line by itself.
% So there is no reason why there should be any text here.
% For the benefit of the user who did put something there
% (a comment, perhaps)
% we simply issue a warning and drop them.
% The method of testing is explained in Appendix~D, p.\ 376 of
% the \TeX{}book. We use \verb?^^M? instead of the \verb?!?
% character used there
% since this is a character that cannot appear in \verb?#1?.
% The two \cs{noexpand} primitives are necessary to avoid
% expansion of active characters and macros.
%
% One extra subtlety should be noted here: remember that
% the token list we are currently building will first be
% processed by the \cs{lowercase} primitive before \TeX{}
% carries out the definitions.
% This means that the `\texttt{C}' character in the
% argument to the \cs{@warning} macro must be protected against
% being changed to `\texttt{c}'. That's the reason why we added the
% \verb?\lccode`\C=`\C? assignment above.
% We can now finish the argument to \cs{lowercase} as well as the
% group in which the category codes were changed.
% \begin{macrocode}
\def\verbatim@rescan#1#2~{\if\noexpand~\noexpand#2~\else
\@warning{Characters dropped after `\string\end{#1}'}\fi}}

% \subsubsection{The \cs{verbatiminput} command}
%
% \begin{macro}{\verbatim@in@stream}
% We begin by allocating an input stream (out of the 16 available
% input streams).
% \begin{macrocode}
\newread\verbatim@in@stream
% \end{macrocode}
% \end{macro}
%
% \begin{macro}{\verbatim@readfile}
% The macro \cs{verbatim@readfile} encloses the main loop by calls to
% the macros \cs{verbatim@startline} and \cs{verbatim@finish},
% respectively. This makes sure
% that the user can initialize and finish the command when the file
% is empty or doesn't exist. The \texttt{verbatim} environment has a
% similar behaviour when called with an empty text.
% \begin{macrocode}
\def\verbatim@readfile#1{%
\verbatim@startline
% \end{macrocode}
% When the file is not found we issue a warning.
% \begin{macrocode}
\openin\verbatim@in@stream #1\relax
\ifeof\verbatim@in@stream
\typeout{No file #1.}%
\else
% \end{macrocode}
% At this point we pass the name of the file to \cs{@addtofilelist}
% so that its appears appears in the output of a \cs{listfiles}
% command.
% In addition, we use \cs{ProvidesFile} to make a log entry in the
% transcript file and to distinguish files read in via
% \cs{verbatiminput} from others.
% \begin{macrocode}
\@addtofilelist{#1}%
\ProvidesFile{#1}[(verbatim)]%
% \end{macrocode}
% While reading from the file it is useful to switch off the
% recognition of the end-of-line character. This saves us stripping
% off spaces from the contents of the line.

% \end{macro}
%
% \begin{macro}{\verbatim@read@file}

% \end{macrocode}
% Without \cs{expandafter} each call of \cs{verbatim@read@file} uses

% \begin{macro}{\add@special}
% This helper macro adds its argument to the

% Way back when DA sent me a pre-release copy of v0.6 of his \Lpack{framed}
% package~\cite{FRAMED}.
% We also discussed good ways of embedding it into the class. One result
% being that I defined some some items \cs{AtBeginDocument}, but this is
% no longer required as DA has changed \Lpack{framed} to cooperate
% with memoir. We continue to have sporadic email conversations about the
% interaction of \Lpack{memoir} and \Lpack{framed}.
%
% Here is a modified version of \file{framed.sty}. In particular
% I moved some of DA's description of the code into the general commentary
% instead of comments within the code.

%====================== Begin Instructions =======================
%
% framed.sty
% ~~~~~~~~~~
% Create framed, shaded, or differently highlighted regions that can
% break across pages. The environments defined are
% framed -- ordinary frame box (\fbox) with edge at margin
% shaded -- shaded background (\colorbox) bleeding into margin
% snugshade -- similar
% leftbar -- thick vertical line in left margin
% to be used like
% \begin{framed}
% copious text
% \end{framed}
%
% But the more general purpose of this package is to facilitate the
% creation of environments that enable page breaking
% within arbitrary decorations using a simple new-environment definition
% incorporating \FrameCommand and
% \begin{MakeFramed}{settings} ... \end{MakeFramed}
%
% The "framed" environment uses "\fbox" as its "\FrameCommand" with
% the additional settings \fboxrule=\FrameRule and \fboxsep=\FrameSep.
% You can change these lengths (using \setlength) and you can change
% the definition of \FrameCommand to use much fancier boxes.
%
% In fact, the "shaded" environment just redefines \FrameCommand to be
% \colorbox{shadecolor} (and you have to define the color "shadecolor":
% \definecolor{shadecolor}...).
%
% A page break is allowed, and even encouraged, before the framed
% environment. If you want to attach some text (a box title) to the
% frame, then the text should be inserted by \FrameCommand.
%
% The contents of the framed regions are restricted:
% Floats, footnotes, marginpars and head-line entries will be lost.
% (Some of these may be handled in a later version.)
% This package will not work with the page breaking of multicol.sty,
% or other systems that perform column-balancing.
%
% The MakeFramed environment does the work. Its "settings" argument
% should contain any adjustments to the text width (applied to \hsize,
% and using the "\width" of the frame itself) as well as a "restore"
% command -- \@parboxrestore or \FrameRestore or something similar;
% as an example, the snugshade environment shows how to suppress excess
% spacing within the box, copying the code from minipage.
%
% Expert commands:
% \MakeFramed, \endMakeFramed: the "MakeFramed" environment
% \FrameCommand: command to draw the frame around its argument
% \FrameRestore: restore some text settings, but fewer than \@parboxrestore
% \FrameRule: length register; \fboxrule for default "framed".
% \FrameSep: length register; \fboxsep for default "framed".
% \FrameHeightAdjust: macro; height of frame above baseline at top of page
%
% This is still a `pre-production' version because I can think of many
% features/improvements that should be made. Nevertheless, starting
% with version 0.5 it should be bug-free.
%
% ToDo:
% Test more varieties of list
% Improve and correct documentation
% Propagation of \marks
% Handle footnotes (how??) floats (?) and marginpars.
% Stretchability modification.

% \subsection{Changing counters}
%
% In LaTeX, a new counter called, say `ctr', is created by the command
% \verb?\newcounter{ctr}[within]?. If the optional within argument is given
% the the counter `ctr' is reset to zero each time the counter `within'
% changes. The command \cs{thectr} typesets the value of the counter ctr.
% This is automatically defined by \cs{newcounter} and is initialised
% to typeset arabic numerals. Sometimes it may be desireable to change
% the counter definitions.
%
% The following code is based on the \Lpack{chngcntr} package~\cite{CHNGCNTR}.
%
% \begin{macro}{\@removefromreset}
% This code uses David Carlisle's \cs{@removefromreset} command as
% specified in the remreset package~\cite{REMRESET}.
% It is provided here as a convenience to the user, and with
% David Carlisle's permission.

% after one of these commands, use \verb?\setcounter{ctr}{...}?, and to change
% the typeseting style use \verb?\renewcommand{\thectr}{...}?.

% \subsection{Odd/even page checking}
%
% It is difficult to check robustly if the current page is odd or even.
% This code, which is based on the \Lpack{chngpage} package~\cite{CHNGPAGE},
% provides a method that has proved (so far) to be robust.
% It works by writing out a label and on the next LaTeX run checks
% the page reference for the label.

% it sets it to FALSE.
%
% This is now fixed so that it should work for non-arabic page numbering.

% \subsection{A fix for two column headings}
%
%
% This is from a posting by Donald Arseneau to \ctt{} on 23 April 2001 to fix
% a problem --- `When I use \verb?\onecolumn\chapter...? its headline
% is printed lower on the page than for two-column chapters'
%
% DA and I had previously discussed this in relation to the Index
% and I had put a hack into the \Lpack{tocbibind} package to fix the Index.
%
% Donald posted the following.
%
% \cs{vspace*} gives bad spacing after a pagebreak and \cs{@makechapterhead}
% starts with \cs{vspace*}.
% The biggest problem is the definition of \cs{@topnewpage}, which is used
% for the two-column spanning text. Here is a redefinition:

%
% Although the author of the \Lpack{caption} package has, over the years,

% The \Lpack{caption} package checks the definitions of the \cs{@makecaption},
