93 % \chapter{About the \strayman\ document class}
95 % The standard \LaTeX\ document classes are all very well for simple
96 % documents, but the style isn't appropriate for works like manuals.
97 % The \strayman\ document class is an attempt to recitfy this situataion,
98 % providing an attractive and distinctive style for Straylight documents.
99 % The layout is based on an earlier style built for \emph{Impression}
100 % documents, although many improvements have been made. This document
101 % was typeset using \strayman, and it demonstrates the design far better
102 % than I can describe it.
105 % \section{Document class options}
107 % The document class provides many options, most of which are taken from
108 % the standard \LaTeX\ classes.
110 % \begin{description}
111 % \def\|{\ensuremath\vert}
113 % \item [\texttt{a4paper} \| \texttt{a5paper} \| \texttt{b5paper} \|
114 % \texttt{letterpaper} \| \texttt{legalpaper} \|
115 % \texttt{executivepaper}] Select the output paper size. Since
116 % \strayman\ is intended to be used mainly for manuals, the default
119 % \item [\texttt{landscape}] Swaps the width and height of the paper.
120 % Probably not much use, to be honest.
122 % \item [\texttt{9pt} \| \texttt{10pt} \| \texttt{11pt} \| \texttt{12pt}]
123 % Selects the basic type size for the document. The |9pt| option is
124 % nonstandard, but it is the default, since larger sizes don't work
127 % \item [\texttt{text}] Sets up the page layout and fonts so that the
128 % output can be converted fairly easily into a raw text file.
130 % \item [\texttt{oneside} \| \texttt{twoside}] Selects one- or two-sided
131 % page layouts. Note that one-sided output doesn't look too good.
133 % \item [\texttt{draft} \| \texttt{final}] Select various options for draft
136 % \item [\texttt{titlepage} \| \texttt{notitlepage}] Selects whether
137 % the |\maketitle| displays its output on a separate title page.
139 % \item [\texttt{openright} \| \texttt{openany}] Select whether chapters
140 % start only on quarto pages, or any page. The default is |openright|.
142 % \item [\texttt{onecolumn} \| \texttt{twocolumn}] Choose whether the
143 % main body text is set in one or two columns. Note that this uses
144 % \LaTeX's built-in column handling, not the \package{multicol}
147 % \item [\texttt{leqno}] Put the equation numbers on the left, not the
150 % \item [\texttt{fleqn}] Typeset displayed equations left aligned.
152 % \item [\texttt{openbib}] Use the `open' style for the bibliography.
154 % \item [\texttt{article}] Change the formatting slightly, in a way more
155 % suited to short documents.
157 % \item [\texttt{square} \| \texttt{rounded}] These options are passed
158 % directly to the \package{syntax} package, when it's loaded.
160 % \item [\texttt{helvetica}] Typeset headings in the Helvetica font,
161 % not in Computer Modern.
163 % \item [\texttt{palatino}] Typeset the main body text in Palatino, and
164 % headings in Helvetica. The |\tt| font is changed to Courier, but
165 % see the \texttt{cmtt} option.
167 % \item [\texttt{times}] Typeset the main body text in Times, and headings
168 % in Helvetica. The |\tt| font is changed to Courier, but see the
169 % \texttt{cmtt} option.
174 % \section{The \texttt{text} option}
176 % In order to facilitate creation of attractively formatted text files
177 % from \LaTeX\ documents, \strayman\ provides a |text| option. This will
178 % set up \emph{all} the fonts to be monospaced, in the same size. The page
179 % size is set up to be a multiple of the character size. The command
181 % "dvi2tty -e-17" <filename>
183 % appears to produce a reasonable output from a DVI file created in this
184 % way. The output will need to be formatted and corrected slightly by hand
185 % although there's a good deal less work to do than might be required
189 % \section{That's it}
191 % That's all I'm writing for now. It's a document class. It defines the
192 % style. What more do you expect?
197 % \chapter{Implementation}
199 % \section{Options handling}
201 % From here on, a lot of the code is shamelessly borrowed from
202 % \file{book.cls} and other places. This is what code re-use is for.
204 % This bit handles all the options on the |\documentclass| command, either
205 % altering our own internal arguments, or loading other packages as

339 % \LaTeX\ way of doing this. This is a \riscos\ thing mainly: I don't like

623 % \subsection{Paragraph layout}
625 % Here we define various paragraph layout parameters.
627 % First, set up the line separation parameters. |\baselineskip| is set
628 % up by the individual size commands.
636 % We don't try to stretch the baselines apart:
639 \renewcommand\baselinestretch{}
642 % We don't indent paragraphs at all; instead, we separate them with blank
643 % lines. The vertical gap is worked out in the size command; we just clear
650 % Set up some standard penalty values.
659 % \subsection{Page layout}
661 % Our layout is a bit different to the standard \LaTeX\ ones: we leave a lot
662 % of space down the left hand side: this is reserved for headings and
665 % Calculating the size of the space on the left, which we call |\leftindent|,
666 % is complicated. We want to use as much of the width of the page as
667 % possible, unlike the \LaTeX\ defaults, making sure that we can fit on
668 % 77 columns of |\listingsize\tt| text. We also try to make space for a
669 % reasonable amount of marginal text, although we don't worry too much if
672 % The calculation is done as follows. More than about 40\,mm of margin will
673 % look very strange. We must have at least 104\,mm of main text, which
674 % leaves 20\,mm for the notes on A5 paper (actually, 17\,mm, since we leave
675 % 3\,mm gap between the notes and the main text). We divide the page
676 % horizontally into $s$\,mm of left border, $m$\,mm of marginal notes,

1366 % which seem to require different spacing. In a double-column layout,
1367 % the title is normally one |\baselineskip| too high. Also, the space I

2589 % Because of the strange layout of the pages, text which is centred using
2590 % normal \LaTeX\ commands is centred in the text area, not on the page,
2591 % which is undesirable for large headings, like part headings.

2596 % It should only be used from outer vertical mode.

2618 % The \strayman\ class uses \package{fancyheadings} for its headers
2619 % and footers. This has already been included in the preamble. We now
2620 % need to fix a few problems with \package{fancyheadings} and set up some
2623 % \begin{macro}{\title}
2625 % We extend |\title|, and give it an optional argument. It can now specify
2626 % the document title as used by |\maketitle| and the running title for the
2627 % header separately.
2629 % We store the running header in the macro |\@headertitle|, which is
2636 % Now we define the |\title| macro, using |\@dblarg| to duplicate the
2637 % mandatory argument if the optional one is omitted.

2714 % The standard \LaTeX\ |\parbox| command, and the \env{minipage} environment,
