65 % \chapter{About the \strayman\ document class}
67 % The standard \LaTeX\ document classes are all very well for simple
68 % documents, but the style isn't appropriate for works like manuals.
69 % The \strayman\ document class is an attempt to rectify this situation,
70 % providing an attractive and distinctive style for Straylight documents.
71 % The layout is based on an earlier style built for \emph{Impression}
72 % documents, although many improvements have been made. This document
73 % was typeset using \strayman, and it demonstrates the design far better
74 % than I can describe it.
77 % \section{Document class options}
79 % The document class provides many options, most of which are taken from
80 % the standard \LaTeX\ classes.
83 % \def\|{\ensuremath\vert}
85 % \item [\texttt{a4paper} \| \texttt{a5paper} \| \texttt{b5paper} \|
86 % \texttt{letterpaper} \| \texttt{legalpaper} \|
87 % \texttt{executivepaper}] Select the output paper size. Since
88 % \strayman\ is intended to be used mainly for manuals, the default
91 % \item [\texttt{landscape}] Swaps the width and height of the paper.
92 % Probably not much use, to be honest.
94 % \item [\texttt{9pt} \| \texttt{10pt} \| \texttt{11pt} \| \texttt{12pt}]
95 % Selects the basic type size for the document. The |9pt| option is
96 % nonstandard, but it is the default, since larger sizes don't work
99 % \item [\texttt{text}] Sets up the page layout and fonts so that the
100 % output can be converted fairly easily into a raw text file.
102 % \item [\texttt{oneside} \| \texttt{twoside}] Selects one- or two-sided
103 % page layouts. Note that one-sided output doesn't look too good.
105 % \item [\texttt{draft} \| \texttt{final}] Select various options for draft
108 % \item [\texttt{titlepage} \| \texttt{notitlepage}] Selects whether
109 % the |\maketitle| displays its output on a separate title page.
111 % \item [\texttt{openright} \| \texttt{openany}] Select whether chapters
112 % start only on quarto pages, or any page. The default is |openright|.
114 % \item [\texttt{onecolumn} \| \texttt{twocolumn}] Choose whether the
115 % main body text is set in one or two columns. Note that this uses
116 % \LaTeX's built-in column handling, not the \package{multicol}
119 % \item [\texttt{leqno}] Put the equation numbers on the left, not the
122 % \item [\texttt{fleqn}] Typeset displayed equations left aligned.
124 % \item [\texttt{openbib}] Use the `open' style for the bibliography.
126 % \item [\texttt{article}] Change the formatting slightly, in a way more
127 % suited to short documents.
129 % \item [\texttt{square} \| \texttt{rounded}] These options are passed
130 % directly to the \package{syntax} package, when it's loaded.
135 % \section{The \texttt{text} option}
137 % In order to facilitate creation of attractively formatted text files
138 % from \LaTeX\ documents, \strayman\ provides a |text| option. This will
139 % set up \emph{all} the fonts to be monospaced, in the same size. The page
140 % size is set up to be a multiple of the character size. The command
142 % "dvi2tty -e-17" <filename>
144 % appears to produce a reasonable output from a DVI file created in this
145 % way. The output will need to be formatted and corrected slightly by hand
146 % although there's a good deal less work to do than might be required
150 % \section{That's it}
152 % That's all I'm writing for now. It's a document class. It defines the
153 % style. What more do you expect?
158 % \chapter{Implementation}
160 % \section{Options handling}
162 % From here on, a lot of the code is shamelessly borrowed from
163 % \file{book.cls} and other places. This is what code re-use is for.
165 % This bit handles all the options on the |\documentclass| command, either
166 % altering our own internal arguments, or loading other packages as

323 % \LaTeX\ way of doing this. This is a \riscos\ thing mainly: I don't like

610 % \subsection{Paragraph layout}
612 % Here we define various paragraph layout parameters.
614 % First, set up the line separation parameters. |\baselineskip| is set
615 % up by the individual size commands.
623 % We don't try to stretch the baselines apart:
626 \renewcommand\baselinestretch{}
629 % Paragraph indentation is set up later.
631 % Set up some standard penalty values.
640 % \subsection{Page layout}
642 % Our layout is a bit different to the standard \LaTeX\ ones: we leave a lot
643 % of space down the left hand side: this is reserved for headings and
646 % Calculating the size of the space on the left, which we call |\leftindent|,
647 % is complicated. We want to use as much of the width of the page as
648 % possible, unlike the \LaTeX\ defaults, making sure that we can fit on
649 % 77 columns of |\listingsize\tt| text. We also try to make space for a
650 % reasonable amount of marginal text, although we don't worry too much if
653 % The calculation is done as follows. More than about 40\,mm of margin will
654 % look very strange. We must have at least 104\,mm of main text, which
655 % leaves 20\,mm for the notes on A5 paper (actually, 17\,mm, since we leave
656 % 3\,mm gap between the notes and the main text). We divide the page
657 % horizontally into $s$\,mm of left border, $m$\,mm of marginal notes,
658 % $t$\,mm of body text, and another $s$\,mm of right border, giving
659 % a total of $w$\,mm. The value $s$ is given to us by the parameter
662 % Articles look odd with a big gap down the side, so this is reduced when
665 % We calculate the quantity~$m$ as $\min\bigl(40,17(w-2s-3)/121+3\bigr)$\@.

1395 % the title is normally one |\baselineskip| too high. Also, the space I
