74 % \chapter{About the \strayman\ document class}
76 % The standard \LaTeX\ document classes are all very well for simple
77 % documents, but the style isn't appropriate for works like manuals.
78 % The \strayman\ document class is an attempt to rectify this situation,
79 % providing an attractive and distinctive style for Straylight documents.
80 % The layout is based on an earlier style built for \emph{Impression}
81 % documents, although many improvements have been made. This document
82 % was typeset using \strayman, and it demonstrates the design far better
83 % than I can describe it.
86 % \section{Document class options}
88 % The document class provides many options, most of which are taken from
89 % the standard \LaTeX\ classes.
92 % \def\|{\ensuremath\vert}
94 % \item [\texttt{a4paper} \| \texttt{a5paper} \| \texttt{b5paper} \|
95 % \texttt{letterpaper} \| \texttt{legalpaper} \|
96 % \texttt{executivepaper}] Select the output paper size. Since
97 % \strayman\ is intended to be used mainly for manuals, the default
100 % \item [\texttt{landscape}] Swaps the width and height of the paper.
101 % Probably not much use, to be honest.
103 % \item [\texttt{9pt} \| \texttt{10pt} \| \texttt{11pt} \| \texttt{12pt}]
104 % Selects the basic type size for the document. The |9pt| option is
105 % nonstandard, but it is the default, since larger sizes don't work
108 % \item [\texttt{text}] Sets up the page layout and fonts so that the
109 % output can be converted fairly easily into a raw text file.
111 % \item [\texttt{oneside} \| \texttt{twoside}] Selects one- or two-sided
112 % page layouts. Note that one-sided output doesn't look too good.
114 % \item [\texttt{draft} \| \texttt{final}] Select various options for draft
117 % \item [\texttt{titlepage} \| \texttt{notitlepage}] Selects whether
118 % the |\maketitle| displays its output on a separate title page.
120 % \item [\texttt{openright} \| \texttt{openany}] Select whether chapters
121 % start only on quarto pages, or any page. The default is |openright|.
123 % \item [\texttt{onecolumn} \| \texttt{twocolumn}] Choose whether the
124 % main body text is set in one or two columns. Note that this uses
125 % \LaTeX's built-in column handling, not the \package{multicol}
128 % \item [\texttt{leqno}] Put the equation numbers on the left, not the
131 % \item [\texttt{fleqn}] Typeset displayed equations left aligned.
133 % \item [\texttt{openbib}] Use the `open' style for the bibliography.
135 % \item [\texttt{article}] Change the formatting slightly, in a way more
136 % suited to short documents.
138 % \item [\texttt{square} \| \texttt{rounded}] These options are passed
139 % directly to the \package{syntax} package, when it's loaded.
141 % \item [\texttt{helvetica}] Typeset headings in the Helvetica font,
142 % not in Computer Modern.
144 % \item [\texttt{palatino}] Typeset the main body text in Palatino, and
145 % headings in Helvetica. The |\tt| font is changed to Courier, but
146 % see the \texttt{cmtt} option.
148 % \item [\texttt{times}] Typeset the main body text in Times, and headings
149 % in Helvetica. The |\tt| font is changed to Courier, but see the
150 % \texttt{cmtt} option.
155 % \section{The \texttt{text} option}
157 % In order to facilitate creation of attractively formatted text files
158 % from \LaTeX\ documents, \strayman\ provides a |text| option. This will
159 % set up \emph{all} the fonts to be monospaced, in the same size. The page
160 % size is set up to be a multiple of the character size. The command
162 % "dvi2tty -e-17" <filename>
164 % appears to produce a reasonable output from a DVI file created in this
165 % way. The output will need to be formatted and corrected slightly by hand
166 % although there's a good deal less work to do than might be required
170 % \section{That's it}
172 % That's all I'm writing for now. It's a document class. It defines the
173 % style. What more do you expect?
178 % \chapter{Implementation}
180 % \section{Options handling}
182 % From here on, a lot of the code is shamelessly borrowed from
183 % \file{book.cls} and other places. This is what code re-use is for.
185 % This bit handles all the options on the |\documentclass| command, either
186 % altering our own internal arguments, or loading other packages as

319 % as the size specifier, rather than the filename, which is the normal
320 % \LaTeX\ way of doing this. This is a \riscos\ thing mainly: I don't like
321 % loads of directories cluttering up my disk, and it means that I can move
322 % the whole of the \strayman\ stuff around as one directory.

600 % \subsection{Paragraph layout}
602 % Here we define various paragraph layout parameters.
604 % First, set up the line separation parameters. |\baselineskip| is set
605 % up by the individual size commands.
613 % We don't try to stretch the baselines apart:
616 \renewcommand\baselinestretch{}
619 % We don't indent paragraphs at all; instead, we separate them with blank
620 % lines. The vertical gap is worked out in the size command; we just clear
627 % Set up some standard penalty values.
636 % \subsection{Page layout}
638 % Our layout is a bit different to the standard \LaTeX\ ones: we leave a lot
639 % of space down the left hand side: this is reserved for headings and
642 % Calculating the size of the space on the left, which we call |\leftindent|,
643 % is complicated. We want to use as much of the width of the page as
644 % possible, unlike the \LaTeX\ defaults, making sure that we can fit on
645 % 77 columns of |\listingsize\tt| text. We also try to make space for a
646 % reasonable amount of marginal text, although we don't worry too much if
649 % The calculation is done as follows. More than about 40\,mm of margin will
650 % look very strange. We must have at least 104\,mm of main text, which
651 % leaves 20\,mm for the notes on A5 paper (actually, 17\,mm, since we leave
652 % 3\,mm gap between the notes and the main text). We divide the page
653 % horizontally into $s$\,mm of left border, $m$\,mm of marginal notes,
654 % $t$\,mm of body text, and another $s$\,mm of right border, giving
655 % a total of $w$\,mm. The value $s$ is given to us by the parameter
658 % Articles look odd with a big gap down the side, so this is reduced when
661 % We calculate the quantity~$m$ as $\min\bigl(40,17(w-2s-3)/121+3\bigr)$\@.
662 % Then we calculate $t=w-m-24-3$.

1344 % the title is normally one |\baselineskip| too high. Also, the space I

2585 % Because of the strange layout of the pages, text which is centred using
2586 % normal \LaTeX\ commands is centred in the text area, not on the page,
2587 % which is undesirable for large headings, like part headings.

2614 % The \strayman\ class uses \package{fancyheadings} for its headers
2615 % and footers. This has already been included in the preamble. We now
2616 % need to fix a few problems with \package{fancyheadings} and set up some
2619 % \begin{macro}{\title}
2621 % We extend |\title|, and give it an optional argument. It can now specify
2622 % the document title as used by |\maketitle| and the running title for the
2623 % header separately.
2625 % We store the running header in the macro |\@headertitle|, which is
2632 % Now we define the |\title| macro, using |\@dblarg| to duplicate the
2633 % mandatory argument if the optional one is omitted.

2648 % inside of the header on of each page. This can be used for security
2649 % classifications, for example. Any \package{fancyheadings} commands can
2650 % be used to control the header, which is expanded on each page.

2710 % The standard \LaTeX\ |\parbox| command, and the \env{minipage} environment,
