102 % \chapter{About the \strayman\ document class}
104 % The standard \LaTeX\ document classes are all very well for simple
105 % documents, but the style isn't appropriate for works like manuals.
106 % The \strayman\ document class is an attempt to recitfy this situataion,
107 % providing an attractive and distinctive style for Straylight documents.
108 % The layout is based on an earlier style built for \emph{Impression}
109 % documents, although many improvements have been made. This document
110 % was typeset using \strayman, and it demonstrates the design far better
111 % than I can describe it.
114 % \section{Document class options}
116 % The document class provides many options, most of which are taken from
117 % the standard \LaTeX\ classes.
119 % \begin{description}
120 % \def\|{\ensuremath\vert}
122 % \item [\texttt{a4paper} \| \texttt{a5paper} \| \texttt{b5paper} \|
123 % \texttt{letterpaper} \| \texttt{legalpaper} \|
124 % \texttt{executivepaper}] Select the output paper size. Since
125 % \strayman\ is intended to be used mainly for manuals, the default
128 % \item [\texttt{landscape}] Swaps the width and height of the paper.
129 % Probably not much use, to be honest.
131 % \item [\texttt{9pt} \| \texttt{10pt} \| \texttt{11pt} \| \texttt{12pt}]
132 % Selects the basic type size for the document. The |9pt| option is
133 % nonstandard, but it is the default, since larger sizes don't work
136 % \item [\texttt{text}] Sets up the page layout and fonts so that the
137 % output can be converted fairly easily into a raw text file.
139 % \item [\texttt{oneside} \| \texttt{twoside}] Selects one- or two-sided
140 % page layouts. Note that one-sided output doesn't look too good.
142 % \item [\texttt{draft} \| \texttt{final}] Select various options for draft
145 % \item [\texttt{titlepage} \| \texttt{notitlepage}] Selects whether
146 % the |\maketitle| displays its output on a separate title page.
148 % \item [\texttt{openright} \| \texttt{openany}] Select whether chapters
149 % start only on quarto pages, or any page. The default is |openright|.
151 % \item [\texttt{onecolumn} \| \texttt{twocolumn}] Choose whether the
152 % main body text is set in one or two columns. Note that this uses
153 % \LaTeX's built-in column handling, not the \package{multicol}
156 % \item [\texttt{leqno}] Put the equation numbers on the left, not the
159 % \item [\texttt{fleqn}] Typeset displayed equations left aligned.
161 % \item [\texttt{openbib}] Use the `open' style for the bibliography.
163 % \item [\texttt{article}] Change the formatting slightly, in a way more
164 % suited to short documents.
166 % \item [\texttt{square} \| \texttt{rounded}] These options are passed
167 % directly to the \package{syntax} package, when it's loaded.
169 % \item [\texttt{helvetica}] Typeset headings in the Helvetica font,
170 % not in Computer Modern.
172 % \item [\texttt{palatino}] Typeset the main body text in Palatino, and
173 % headings in Helvetica. The |\tt| font is changed to Courier, but
174 % see the \texttt{cmtt} option.
176 % \item [\texttt{times}] Typeset the main body text in Times, and headings
177 % in Helvetica. The |\tt| font is changed to Courier, but see the
178 % \texttt{cmtt} option.
183 % \section{The \texttt{text} option}
185 % In order to facilitate creation of attractively formatted text files
186 % from \LaTeX\ documents, \strayman\ provides a |text| option. This will
187 % set up \emph{all} the fonts to be monospaced, in the same size. The page
188 % size is set up to be a multiple of the character size. The command
190 % "dvi2tty -e-17" <filename>
192 % appears to produce a reasonable output from a DVI file created in this
193 % way. The output will need to be formatted and corrected slightly by hand
194 % although there's a good deal less work to do than might be required
198 % \section{That's it}
200 % That's all I'm writing for now. It's a document class. It defines the
201 % style. What more do you expect?
206 % \chapter{Implementation}
208 % \section{Options handling}
210 % From here on, a lot of the code is shamelessly borrowed from
211 % \file{book.cls} and other places. This is what code re-use is for.
213 % This bit handles all the options on the |\documentclass| command, either
214 % altering our own internal arguments, or loading other packages as

345 % The text sizing is rather messy. We store this in a separate file. To
346 % keep this stuff away from other classes, we use the file \emph{extension}
347 % as the size specifier, rather than the filename, which is the normal
348 % \LaTeX\ way of doing this. This is a \riscos\ thing mainly: I don't like
349 % loads of directories cluttering up my disk, and it means that I can move
350 % the whole of the \strayman\ stuff around as one directory.

628 % \subsection{Paragraph layout}
630 % Here we define various paragraph layout parameters.
632 % First, set up the line separation parameters. |\baselineskip| is set
633 % up by the individual size commands.
641 % We don't try to stretch the baselines apart:
644 \renewcommand\baselinestretch{}
647 % We don't indent paragraphs at all; instead, we separate them with blank
648 % lines. The vertical gap is worked out in the size command; we just clear
655 % Set up some standard penalty values.
664 % \subsection{Page layout}
666 % Our layout is a bit different to the standard \LaTeX\ ones: we leave a lot
667 % of space down the left hand side: this is reserved for headings and
670 % Calculating the size of the space on the left, which we call |\leftindent|,
671 % is complicated. We want to use as much of the width of the page as
672 % possible, unlike the \LaTeX\ defaults, making sure that we can fit on
673 % 77 columns of |\listingsize\tt| text. We also try to make space for a
674 % reasonable amount of marginal text, although we don't worry too much if
677 % The calculation is done as follows. More than about 40\,mm of margin will
678 % look very strange. We must have at least 104\,mm of main text, which
679 % leaves 20\,mm for the notes on A5 paper (actually, 17\,mm, since we leave
680 % 3\,mm gap between the notes and the main text). We divide the page
681 % horizontally into $s$\,mm of left border, $m$\,mm of marginal notes,
682 % $t$\,mm of body text, and another $s$\,mm of right border, giving

1372 % the title is normally one |\baselineskip| too high. Also, the space I

2613 % Because of the strange layout of the pages, text which is centred using
2614 % normal \LaTeX\ commands is centred in the text area, not on the page,
2615 % which is undesirable for large headings, like part headings.

2650 % the document title as used by |\maketitle| and the running title for the
2651 % header separately.
2653 % We store the running header in the macro |\@headertitle|, which is
