75 | % \chapter{About the \strayman\ document class} | |
76 | % | |
77 | % The standard \LaTeX\ document classes are all very well for simple | |
78 | % documents, but the style isn't appropriate for works like manuals. | |
8a0490fb | 79 | % The \strayman\ document class is an attempt to rectify this situation, |
1ffa9044 | 80 | % providing an attractive and distinctive style for Straylight documents. |
81 | % The layout is based on an earlier style built for \emph{Impression} | |
82 | % documents, although many improvements have been made. This document | |
83 | % was typeset using \strayman, and it demonstrates the design far better | |
84 | % than I can describe it. | |
85 | % | |
86 | % | |
87 | % \section{Document class options} | |
88 | % | |
89 | % The document class provides many options, most of which are taken from | |
90 | % the standard \LaTeX\ classes. | |
91 | % | |
92 | % \begin{description} | |
93 | % \def\|{\ensuremath\vert} | |
94 | % | |
95 | % \item [\texttt{a4paper} \| \texttt{a5paper} \| \texttt{b5paper} \| | |
96 | % \texttt{letterpaper} \| \texttt{legalpaper} \| | |
97 | % \texttt{executivepaper}] Select the output paper size. Since | |
98 | % \strayman\ is intended to be used mainly for manuals, the default | |
99 | % size is |a5paper|. | |
100 | % | |
101 | % \item [\texttt{landscape}] Swaps the width and height of the paper. | |
102 | % Probably not much use, to be honest. | |
103 | % | |
104 | % \item [\texttt{9pt} \| \texttt{10pt} \| \texttt{11pt} \| \texttt{12pt}] | |
105 | % Selects the basic type size for the document. The |9pt| option is | |
106 | % nonstandard, but it is the default, since larger sizes don't work | |
107 | % well on A5~paper. | |
108 | % | |
109 | % \item [\texttt{text}] Sets up the page layout and fonts so that the | |
110 | % output can be converted fairly easily into a raw text file. | |
111 | % | |
112 | % \item [\texttt{oneside} \| \texttt{twoside}] Selects one- or two-sided | |
113 | % page layouts. Note that one-sided output doesn't look too good. | |
114 | % | |
115 | % \item [\texttt{draft} \| \texttt{final}] Select various options for draft | |
116 | % or final copy. | |
117 | % | |
118 | % \item [\texttt{titlepage} \| \texttt{notitlepage}] Selects whether | |
119 | % the |\maketitle| displays its output on a separate title page. | |
120 | % | |
121 | % \item [\texttt{openright} \| \texttt{openany}] Select whether chapters | |
122 | % start only on quarto pages, or any page. The default is |openright|. | |
123 | % | |
124 | % \item [\texttt{onecolumn} \| \texttt{twocolumn}] Choose whether the | |
125 | % main body text is set in one or two columns. Note that this uses | |
126 | % \LaTeX's built-in column handling, not the \package{multicol} | |
127 | % package. | |
128 | % | |
129 | % \item [\texttt{leqno}] Put the equation numbers on the left, not the | |
130 | % right. | |
131 | % | |
132 | % \item [\texttt{fleqn}] Typeset displayed equations left aligned. | |
133 | % | |
134 | % \item [\texttt{openbib}] Use the `open' style for the bibliography. | |
135 | % | |
136 | % \item [\texttt{article}] Change the formatting slightly, in a way more | |
137 | % suited to short documents. | |
138 | % | |
139 | % \item [\texttt{square} \| \texttt{rounded}] These options are passed | |
140 | % directly to the \package{syntax} package, when it's loaded. | |
141 | % | |
1ffa9044 | 142 | % \end{description} |
143 | % | |
144 | % | |
145 | % \section{The \texttt{text} option} | |
146 | % | |
147 | % In order to facilitate creation of attractively formatted text files | |
148 | % from \LaTeX\ documents, \strayman\ provides a |text| option. This will | |
149 | % set up \emph{all} the fonts to be monospaced, in the same size. The page | |
150 | % size is set up to be a multiple of the character size. The command | |
151 | % \begin{syndisplay} | |
152 | % "dvi2tty -e-17" <filename> | |
153 | % \end{syndisplay} | |
154 | % appears to produce a reasonable output from a DVI file created in this | |
155 | % way. The output will need to be formatted and corrected slightly by hand | |
156 | % although there's a good deal less work to do than might be required | |
157 | % otherwise. | |
158 | % | |
159 | % | |
160 | % \section{That's it} | |
161 | % | |
162 | % That's all I'm writing for now. It's a document class. It defines the | |
163 | % style. What more do you expect? | |
164 | % | |
165 | % | |
166 | % \implementation | |

170 | % \section{Options handling} | |
171 | % | |
172 | % From here on, a lot of the code is shamelessly borrowed from | |
173 | % \file{book.cls} and other places. This is what code re-use is for. | |
174 | % | |
175 | % This bit handles all the options on the |\documentclass| command, either | |
176 | % altering our own internal arguments, or loading other packages as | |
177 | % appropriate. | |
178 | % | |
179 | % \subsection{Set up some defaults} | |
180 | % | |
181 | % We create some variables to hold the settings, and initialise them to | |
182 | % sensible values. | |

329 | % | |
330 | % The text sizing is rather messy. We store this in a separate file. To | |
331 | % keep this stuff away from other classes, we use the file \emph{extension} | |
332 | % as the size specifier, rather than the filename, which is the normal | |
333 | % \LaTeX\ way of doing this. This is a \riscos\ thing mainly: I don't like | |
334 | % loads of directories cluttering up my disk, and it means that I can move | |
335 | % the whole of the \strayman\ stuff around as one directory. | |

648 | % \end{macrocode} | |
649 | % | |
650 | % \subsection{Page layout} | |
651 | % | |
652 | % Our layout is a bit different to the standard \LaTeX\ ones: we leave a lot | |
653 | % of space down the left hand side: this is reserved for headings and | |
654 | % marginal notes. | |
655 | % | |
656 | % Calculating the size of the space on the left, which we call |\leftindent|, | |
657 | % is complicated. We want to use as much of the width of the page as | |
658 | % possible, unlike the \LaTeX\ defaults, making sure that we can fit on | |
659 | % 77 columns of |\listingsize\tt| text. We also try to make space for a | |
660 | % reasonable amount of marginal text, although we don't worry too much if | |
661 | % that suffers. | |
662 | % | |
663 | % The calculation is done as follows. More than about 40\,mm of margin will | |
664 | % look very strange. We must have at least 104\,mm of main text, which | |
665 | % leaves 20\,mm for the notes on A5 paper (actually, 17\,mm, since we leave | |
666 | % 3\,mm gap between the notes and the main text). We divide the page | |
667 | % horizontally into $s$\,mm of left border, $m$\,mm of marginal notes, | |
668 | % $t$\,mm of body text, and another $s$\,mm of right border, giving | |
669 | % a total of $w$\,mm. The value $s$ is given to us by the parameter | |
670 | % |\pagesurround|. | |
671 | % | |
672 | % Articles look odd with a big gap down the side, so this is reduced when | |
673 | % necessary. | |
674 | % | |
675 | % We calculate the quantity~$m$ as $\min\bigl(40,17(w-2s-3)/121+3\bigr)$\@. | |
676 | % Then we calculate $t=w-m-24-3$. | |

1346 | % \end{macro} | |
1347 | % | |
1348 | % \begin{macro}{\@makechapterhead} | |
1349 | % | |
1350 | % This macro actually does the job of typesetting a chapter heading. Call | |
1351 | % this routine as |\@makechapterhead{|\synt{number}|}{|\synt{title}|}|. | |
1352 | % Here, \synt{number} is how to typeset the chapter number, and \synt{title} | |
1353 | % is the rest of the title. To suppress the number, just leave \synt{number} | |
1354 | % empty. The number is only typeset when it is correct to do so anyway. | |
1355 | % | |
1356 | % The spacing is rather awkward. We have to cope with two-column layouts, | |
1357 | % which seem to require different spacing. In a double-column layout, | |
1358 | % the title is normally one |\baselineskip| too high. Also, the space I | |
1359 | % add at the bottom of the heading gets eaten in double-column chapters, | |
1360 | % because I'm actually typesetting into a vbox which is floated to the top | |
1361 | % by \LaTeX\ in a fairly horrid way. This can't really be worked around, | |
1362 | % so we just make the space beneath the heading equal to |\dbltextfloatsep|, | |
1363 | % which is what gets added anyway. | |
1364 | % | |
1365 | % The other snags are to do with the rule after the chapter heading. | |
1366 | % Firstly, this is meant to be typeset into the left margin, like the | |
1367 | % heading itself, which is a bit messy. More awkwardly, we have to be | |
1368 | % careful not to let the depth of the line vary when the chapter heading has | |
1369 | % descenders, although obviously we must lower the rule if the heading really | |
1370 | % is very deep indeed. | |
1371 | % | |
1372 | % | |
1373 | % We'll approach this a bit at a time. | |
1374 | % | |
1375 | % \begin{macrocode} | |
1376 | \def\@makechapterhead#1#2{% | |
1377 | \begingroup% % Stop my hacking messing things up | |
1378 | % \end{macrocode} | |
1379 | % | |
1380 | % First, the top spacing. This is divided into two parts, by an invisible | |
1381 | % rule: the |\vskip| above the rule is eaten by \TeX\ if this is a genuine | |
1382 | % new page, but put into the floating vbox if this is a two-column affair. | |
1383 | % The second bit is added in both cases. | |
1384 | % | |
1385 | % \begin{macrocode} | |
1386 | \vskip\baselineskip% % This is gobbled in single column | |
1387 | \hrule\@height\z@% % Stops TeX from binning my vskips | |
1388 | \vskip32\p@% % Start chapters in a funny place | |
1389 | % \end{macrocode} | |
1390 | % | |
1391 | % Now we actually typeset the heading. This is fairly simple: we must just | |
1392 | % check that we need to typeset the number. | |
1393 | % | |
1394 | % \begin{macrocode} | |
1395 | \normalfont\Huge\bfseries\headfam% % Choose a nice font for it | |
1396 | \raggedright % Don't justify -- it looks nasty | |
1397 | \@hangfrom{\hskip-\leftindent}% % Start text at `real left margin' | |
1398 | \ifnum\c@secnumdepth>\m@ne% % Do we typeset chapter numbers? | |
1399 | \if@mainmatter% % Are we past the front matter? | |
1400 | #1% % Yes -- then typeset the number | |
1401 | \fi\fi% % Now back to normality | |
1402 | {#2}% % Typeset the actual chapter head | |
1403 | \par\nobreak% % Back to vmode again, please | |
1404 | % \end{macrocode} | |
1405 | % | |
1406 | % The next tricky bit is the space before the ruleoff. We must be careful | |
1407 | % here: | |
1408 | % | |
1409 | % \begin{itemize} | |
1410 | % | |
1411 | % \item We want the rule to be the right depth below the heading baseline, | |
1412 | % regardless of whether the heading contains descenders: helpfully, \TeX\ | |
1413 | % omits |\baselineskip| glue before and after rules. | |
1414 | % | |
1415 | % \item We want the rule to always be below any oddly deep descenders that | |
1416 | % a strange user might throw at us (e.g., horrid fractions or weird | |
1417 | % |\vrule|s). | |
1418 | % | |
1419 | % \end{itemize} | |
1420 | % | |
1421 | % We accomplish this by scrutinising |\prevdepth| carefully. | |
1422 | % | |
1423 | % \begin{macrocode} | |
1424 | \@tempdima14\p@% % Be this low below the baseline | |
1425 | \advance\@tempdima-\prevdepth% % This is the actual skip then | |
1426 | \ifdim\@tempdima<8\p@% % Is this not enough skippage? | |
1427 | \@tempdima8\p@% % No: then skip some more | |
1428 | \fi% | |
1429 | \vskip\@tempdima% % Skip a bit below the title | |
1430 | % \end{macrocode} | |
1431 | % | |
1432 | % Now we can set the rule. This needs a little care. | |
1433 | % | |
1434 | % \begin{macrocode} | |
1435 | \@tempskipa\textwidth% % Find the width of the column | |
1436 | \advance\@tempskipa\leftindent% % Add on the big lefthand gap | |
1437 | \nointerlineskip% % Don't add any more space please | |

1440 | }% | |
1441 | \nointerlineskip% % Don't leave a gap beneath it | |
1442 | % \end{macrocode} | |
1443 | % | |
1444 | % Finally, we leave a gap. In two-column layouts this is done for us, and | |
1445 | % \LaTeX\ gobbles this glue and replaces it with |\dbltextfloatsep|. To make | |
1446 | % things consistent, this is the glue we use anyway. | |

1844 | % \begin{environment}{quotation} | |
1845 | % | |
1846 | % The \env{quotation} environment is a pretty standard display, except that | |

1925 | % \section{Floats} | |
1926 | % | |
1927 | % Since raw \LaTeX\ doesn't actually define any floating objects, we have | |
1928 | % to do some of the work here. This isn't actually terribly arduous. For | |
1929 | % a float called \synt{float}, we have to define the following macros: | |
1930 | % | |
1931 | % \begin{description} | |
1932 | % \let\descriptionlabel\relax | |
1933 | % | |
1934 | % \item[\texttt{\bslash fps@}\synt{float}] is the default float positioning | |
1935 | % argument for the float type. | |
1936 | % | |
1937 | % \item[\texttt{\bslash ftype@}\synt{float}] is a flag bit for the float | |
1938 | % type. This is used in \LaTeX's |\output| routine to identify floats of | |
1939 | % this type. | |
1940 | % | |
1941 | % \item[\texttt{\bslash ext@}\synt{float}] is the file extension for the | |
1942 | % list of these floats (e.g., \lit{lof} for figures). | |
1943 | % | |
1944 | % \item[\texttt{\bslash fnum@}\synt{float}] is a macro which generates the | |
1945 | % caption number. For figures, this expands to `|Figure~\thefigure|'. | |
1946 | % | |
1947 | % \end{description} | |
1948 | % | |
1949 | % We must also define |\@makecaption|, which typesets a float caption in | |
1950 | % an appropriate way, and an environment for each type of float. | |
1951 | % | |
1952 | % \subsection{Figures} | |
1953 | % | |
1954 | % This is all fairly straightforward stuff. First, we create a counter for | |
1955 | % figures: | |
1956 | % | |
1957 | % \begin{macrocode} | |
1958 | \newcounter{figure}[chapter] | |
1959 | \if@article | |
1960 | \renewcommand\thefigure{\@arabic\c@figure} | |
1961 | \else | |
1962 | \renewcommand\thefigure{\thechapter.\@arabic\c@figure} | |
1963 | \fi | |
1964 | % \end{macrocode} | |
1965 | % | |
1966 | % Now we define all the macros \LaTeX\ requires. | |
1967 | % | |
1968 | % \begin{macrocode} | |
1969 | \if@herefloats\def\fps@figure{htbp}\else\def\fps@figure{tbp}\fi | |
1970 | \def\ftype@figure{1} | |

1972 | \def\fnum@figure{\figurename~\thefigure} | |
1973 | % \end{macrocode} | |
1974 | % | |
1975 | % \begin{environment}{figure} | |
1976 | % \begin{environment}{figure*} | |
1977 | % | |
1978 | % Finally, we create the \env{figure} and \env{figure$*$} environments. | |
1979 | % | |
1980 | % \begin{macrocode} | |
1981 | \newenvironment{figure}{\@float{figure}}{\end@float} | |
1982 | \newenvironment{figure*}{\@dblfloat{figure}}{\end@dblfloat} | |
1983 | % \end{macrocode} | |
1984 | % \end{environment} | |
1985 | % \end{environment} | |
1986 | % | |
1987 | % \subsection{Tables} | |
1988 | % | |
1989 | % This is pretty similar to the figure handling. | |
1990 | % | |
1991 | % \begin{macrocode} | |
1992 | \newcounter{table}[chapter] | |

2036 | % \section{Font commands} | |
2037 | % | |
2038 | % We allow the `old' font commands to do sensible \textsf{NFSS} things, since | |
2039 | % we don't have any legacy documents. This means that we have proper | |
2040 | % abbreviations for font changes. We also add |\nm| to return to a normal | |
2041 | % font, whatever that may mean. | |
2042 | % | |
2043 | % \begin{macrocode} | |
2044 | \DeclareOldFontCommand{\rm}{\rmfamily}{\mathrm} | |

2054 | % \end{macrocode} | |
2055 | % | |
2056 | % Now we define some special commands which only work in maths mode. It | |
2057 | % seems that older versions of \LaTeX\ (in particular, that at Warwick | |
2058 | % University) don't define these commands initially, so we'd better not | |
2059 | % use |\renewcommand| after all. We also dispose of lots of messing with | |
2060 | % |\protect| by using |\DeclareRobustCommand|. | |

2067 | % \section{Tables of contents} | |

2070 | % | |
2071 | % \subsection{Contents} | |

2104 | % | |
2105 | % \begin{macro}{\l@part} | |

2127 | % | |
2128 | % We open a group, to avoid messing other things up. The |\numberline| | |
2129 | % macro, which numbers the entry on the left, typesets its argument in a box | |
2130 | % of width |\@tempdima|, which we must set up. We then set up the values | |
2131 | % of |\rightskip| and |\parfillskip| to avoid printing over the page number. | |
2132 | % We also make |\interlinepenalty| infinite to suppress breaking pages in | |
2133 | % the middle of the title. | |

2276 | % \item A |\nobreak| penalty, to stop a break from eating the glue. | |

2279 | % the title is set flush left as a result of this. Otherwise, it is ignored | |
2280 | % because the leaders are |\hfill|. | |
2281 | % | |
2282 | % \item A penalty. This is a reasonable place to break the line if | |
2283 | % necessary. | |
2284 | % | |
2285 | % \item An empty |\hbox|. This stops the following glue from being discarded | |
2286 | % at the beginning of a new line. | |
2287 | % | |
2288 | % \item Another |\nobreak|, which stops a break at the following glue item. | |
2289 | % | |
2290 | % \item The dotted |\leaders|, which have |\hfill| stretchiness. This forces | |
2291 | % the page number to be flush right. | |
2292 | % | |
2293 | % \end{itemize} | |
2294 | % | |
2295 | % The net result of all this is we can now cope with a line break at the | |
2296 | % end of the title, before the page number, which means that the dots are | |
2297 | % put on the next line. The original \LaTeX\ version forced the last word | |

2632 | % \section{Headers and footers} | |
2633 | % | |
2634 | % The \strayman\ class uses \package{fancyheadings} for its headers | |
2635 | % and footers. This has already been included in the preamble. We now | |
2636 | % need to fix a few problems with \package{fancyheadings} and set up some | |
2637 | % macros. | |
2638 | % | |
2639 | % \begin{macro}{\title} | |
2640 | % | |
2641 | % We extend |\title|, and give it an optional argument. It can now specify | |
2642 | % the document title as used by |\maketitle| and the running title for the | |
2643 | % header separately. | |
2644 | % | |
2645 | % We store the running header in the macro |\@headertitle|, which is | |
2646 | % initially empty. | |
2647 | % | |
2648 | % \begin{macrocode} | |
2649 | \def\@headertitle{} | |
2650 | % \end{macrocode} | |
2651 | % | |
2652 | % Now we define the |\title| macro, using |\@dblarg| to duplicate the | |
2653 | % mandatory argument if the optional one is omitted. | |
2654 | % | |
2655 | % \begin{macrocode} | |
2656 | \def\title{\@dblarg\title@i} | |
2657 | \def\title@i[#1]#2{% | |
2658 | \gdef\@title{#2}% | |
2659 | \gdef\@headertitle{#1}% | |
2660 | } | |
2661 | % \end{macrocode} | |
2662 | % \end{macro} | |
2663 | % | |
2664 | % \begin{macro}{\innerhead} | |
2665 | % \begin{macro}{\innerfoot} | |
2666 | % | |
2667 | % We allow the user to specify an `inner heading' which is displayed on the | |
2668 | % inside of the header on of each page. This can be used for security | |
2669 | % classifications, for example. Any \package{fancyheadings} commands can | |
2670 | % be used to control the header, which is expanded on each page. | |
2671 | % | |
2672 | % \begin{macrocode} | |
2673 | \def\l@innerhead{} | |
2674 | \def\r@innerhead{} | |
2675 | \def\l@innerfoot{} | |
2676 | \def\r@innerfoot{} | |
2677 | \def\innerhead{\@dblarg\innerhead@i} | |
2678 | \def\innerhead@i[#1]#2{% | |
2679 | \def\l@innerhead{#1}% | |
2680 | \def\r@innerhead{#2}% | |
2681 | } | |
2682 | \def\innerfoot{\@dblarg\innerfoot@i} | |
2683 | \def\innerfoot@i[#1]#2{% | |
2684 | \def\l@innerfoot{#1}% | |
2685 | \def\r@innerfoot{#2}% | |
2686 | } | |
2687 | % \end{macrocode} | |
2688 | % \end{macro} | |
2689 | % \end{macro} | |
2690 | % | |
2691 | % The next step is to set up the headings: | |
2692 | % | |
2693 | % \begin{macrocode} | |
2694 | \let\headrulewidth\z@ | |
2695 | \headwidth\textwidth | |
2696 | \advance\headwidth\leftindent | |
2697 | \fancypagestyle{headings}{% | |
2698 | \fancyhf{} | |
2699 | \fancyhead[LE]{\bfseries\@headertitle} | |
2700 | \if@article\fancyhead[RO]{\rightmark}\else\fancyhead[RO]{\leftmark}\fi | |
2701 | \fancyhead[RE]{\l@innerhead} \fancyhead[LO]{\r@innerhead} | |
2702 | \fancyfoot[RE]{\l@innerfoot} \fancyfoot[LO]{\r@innerfoot} | |
2703 | \fancyfoot[LE,RO]{\thepage} | |
2704 | } | |
2705 | \fancypagestyle{plain}{% | |
2706 | \fancyhf{}% | |
2707 | \fancyfoot[RE]{\l@innerfoot} \fancyfoot[LO]{\r@innerfoot} | |
2708 | \fancyfoot[LE,RO]{\thepage}% | |
2709 | } | |
2710 | \let\ps@fancy\ps@@fancy | |
2711 | % \end{macrocode} | |
2712 | % | |
2713 | % The \package{fancyheadings} package by default expects pages to be | |
2714 | % symmetrical. We have to redefine the |\ps@fancy| macro to make it | |
2715 | % work properly. | |
2716 | % | |
2717 | % \begin{macrocode} | |
2718 | \def\@lodd{\ifodd\c@page\hss\else\relax\fi} | |
2719 | \def\@rodd{\ifodd\c@page\relax\else\hss\fi} | |
2720 | % \end{macrocode} | |
2721 | % | |
2722 | % Finally, we can choose the page style we want: | |
2723 | % | |
2724 | % \begin{macrocode} | |
2725 | \pagestyle{headings} | |
2726 | % \end{macrocode} | |
2727 | % | |
2728 | % \section{Parbox alteration} | |
2729 | % | |
2730 | % The standard \LaTeX\ |\parbox| command, and the \env{minipage} environment, | |
2731 | % reset |\parskip| to zero, which is inconsistent with the document style. | |
2732 | % We amend |\@arrayparboxrestore|, the macro which sets up the paragraph | |
2733 | % style for parboxes. | |
2734 | % | |
2735 | % First, we define a macro explaining how the parbox should set the spacing. | |
2736 | % | |
2737 | % \begin{macrocode} | |
2738 | \def\parboxparskip{2ex} | |
2739 | % \end{macrocode} | |
2740 | % | |
2741 | % Next, we redefine the macro. This is taken directly from the \LaTeXe | |
2742 | % source. | |
2743 | % | |
2744 | % \begin{macrocode} | |
2745 | \def\@arrayparboxrestore{% | |

2765 | % \subsection{Other typesetting conventions} | |
