While underlining -% is commonly rejected, experts dispute about whether letterspacing -% should be used or not, and in which cases. If you are not interested -% in such debates, you may well skip to the next section. -% -% -% \subsection*{Theory \dots} -% \label{sec:theory} -% -% To understand the experts' arguments we have to know about the -% conception of \emph{page grayness.} The sum of all characters on -% a page represents a certain amount of grayness, provided that -% the letters are printed black onto white paper. -% -% \person{Jan Tschichold} \cite{Tschichold}, a well known and recognized -% typographer, accepts only forms of emphasizing, which do not disturb this -% grayness. This is only true of italic shape, caps, and -% caps-and-small-caps fonts, but not of ordinary letterspacing, underlining, -% bold face type and so on, all of which appear as either dark or light -% spots in the text area. In his opinion emphasized text shall not catch the eye when -% running over the text, but rather when actually reading the respective words. -% -% Other, less restrictive typographers \cite{Willberg} call this kind of emphasizing -% `integrated' or `aesthetic', while they describe `active' emphasizing apart from it, -% which actually \emph{has} to catch the reader's eye. To the latter group belong commonly -% despised things like letterspacing, demibold face type and even underlined and colored text. -% -% On the other hand, \person{Tschichold} suggests -% to space out caps and caps-and-small-caps fonts on title pages, headings and running headers from -% 1\,pt up to 2\,pt. -% Even in running text legibility of uppercase letters should be improved with slight -% letterspacing, since (the Roman) majuscules don't look right, if they are spaced -% like (the Carolingian) minuscules.\footnote{This suggestion is followed throughout this article, -% although Prof.~\person{Knuth} already considered slight letterspacing with his |cmcsc| fonts.} -% -% -% -%\subsection*{\dots\ and Practice} -% -% However, in the last centuries letterspacing was excessively used, -% underlining at least sometimes, because capitals and italic shape could -% not be used together with the \emph{Fraktur} font and other black-letter fonts, -% which are sometimes also called ``old German'' fonts. -% This tradition is widely continued until today. The same limitations apply still today -% to many languages with non-latin glyphs, which is why letterspacing has a strong -% tradition in eastern countries where Cyrillic fonts are used. -% -% The \person{Duden} \cite{Duden}, a well known German dictionary, explains how to space out properly: -% \emph{Punctuation marks are spaced out like letters, except quotation marks and periods. -% Numbers are never spaced out. The German syllable \mbox{\emph{-sche}} is not spaced -% out in cases like \emph{``der {\so{Virchow{sche}}} Versuch''}\footnote{the \person{Virchow} experiment}. -% In the old German \emph{Fraktur} fonts the ligatures \emph{|ch|, |ck|, |sz|~(\ss)} and~\emph{|tz|} are -% not broken within spaced out text.} -% -% While some books follow all these rules \cite{Muszynski}, others don't -% \cite{Reglement}. In fact, most books in my personal library do \emph{not} space out commas. -% -% -% -% -% -% -% -% -% -% \section{Short introduction and common rules} -% -% The \soul\ package provides five commands that are aimed at emphasizing -% text parts. Each of the commands takes one argument that can either be -% the text itself or the name of a macro that contains text (e.\,g.~|\so\text|)^^A -% ^^A -% \footnote{See~\ref{par:Unexpandable material in command sequences} for -% some additional information about the latter mode.}^^A -% ^^A -% . -% See table~\ref{tab:survey} for a complete command survey. -% -% {\catcode`\|=12 -% \begin{center} -% \begin{tabular}{r@{\hspace{1.5em}}l} -% \verb+\so{letterspacing}+&\so{letterspacing}\\ -% \verb+\caps{CAPITALS, Small Capitals}+&\caps{CAPITALS, Small Capitals}\\ -% \verb+\ul{underlining}+&\ul{underlining}\\ -% \verb+\st{overstriking}+&\st{overstriking}\\ -% \verb+\hl{highlighting}+&highlighting\footnotemark\\ -% \end{tabular} -% \end{center} -% \footnotetext{The look of highlighting is nowhere demonstrated -% in this documentation, because it requires a Postscript aware -% output driver and would come out as ugly black bars on other -% devices, looking very much like censoring bars.

The colors can be changed using the following commands: -% -% {\catcode`\|=12 -% \begin{center} -% \begin{tabular}{r@{\hspace{1.5em}}l} -% \verb+\setulcolor{red}+&set underlining color\\ -% \verb+\setstcolor{green}+&set overstriking color\\ -% \verb+\sethlcolor{blue}+&set highlighting color\\ -% \end{tabular} -% \end{center} -% } -% -% \noindent -% |\setulcolor{}| and |\setstcolor{}| turn coloring off. -% There are only few colors predefined by the \package{color} -% package, but you can easily add custom color definitions. -% See the \package{color} package documentation~\cite{color} for further -% information. -% -% \begin{example} -% |\usepackage{color,soul}|\\ -% |\definecolor{lightblue}{rgb}{.90,.95,1}|\\ -% |\sethlcolor{lightblue}|\\ -% |...|\\ -% |\hl{this is highlighted in light blue color}|\\ -% \end{example} -% -% -% -% -% -% -% -% \subsection[Some things work]{Some things work \dots} -% -% The following examples may look boring and redundant, because they describe -% nothing else than common \LaTeX\ notation with a few exceptions, but this is -% only the half story: The \soul\ package has to pre-process the argument -% before it can split it into characters and syllables, and all described -% constructs are only allowed because the package explicitly implements them. -% -% \begin{verblist}{1} -% \item[Accents: \so{na\"\i ve}] -% Accents can be used naturally. -% Support for the following accents is built-in: |\`|, |\'|, |\^|, |\"|, |\~|, -% |\=|, |\.|, |\u|, |\v|, |\H|, |\t|, |\c|, |\d|, |\b|, and |\r|.

If used together with the \package{german} -% package, \soul\ automatically adds the |"| command. -% Let's assume you have defined |\%| to put some weird accent on -% the next character.

This font is used, because it -% has 256~mono-spaced characters without any kerning. -% It belongs to \person{J\"org Knappen'\textrm{s}} -% \caps{EC}-fonts, which should be part of every modern \TeX\ installation. -% If \TeX\ reports ``\texttt{I can't find file `ectt1000'}'' you don't -% seem to have this font installed. It is recommended that -% you install at least the file |ectt1000.tfm| which has less than 1.4\,kB\null. -% Alternatively, you can let the \soul\ package use the |cmtt10| font that -% is part of any installation, or some other mono-spaced font: -% -% \begin{example} -% |\font\SOUL@tt=cmtt10| -% \end{example} -% -% Note, however, that \soul\ does only handle characters, -% for which the internal font has a character with the same -% character code. As |cmtt10| contains only characters with codes -% 0 to~127, you can't typeset characters with codes 128 to~255. -% These 8-bit character codes are used by many fonts with non-ascii -% glyphs. So the |cmtt10| font will, for example, not work for |T2A| -% encoded cyrillic characters. -% -% -% -% -% -% -% -% \subsection{The configuration file} -% \label{sec:config} -% -% If you want to change the predefined settings or add new features, -% then create a file named `|soul.cfg|' and put it in a directory, where \TeX\ -% can find it.

There are just some minor restrictions -% for Non-\LaTeX\ use: -% -% The \cs{\caps} command doesn't use a database, it is only a dumb -% definition with fixed values. It switches to \cs{\capsfont}, which---unless -% defined explicitly like in the following example---won't really change -% the used font at all.

There should always be some reasoning behind changing -% the style, such as ``names of persons shall be typeset in a caps-and-small-caps -% font''. So you declare in your text just that some words are the name of a -% person, while you define in the preamble or, even better, in a separate -% style file how to deal with persons: -% -% \begin{example} -% |\newcommand*\person{\textsc}|\\ -% |...|\\ -% |``I think it's a beautiful day to go to the zoo and feed|\\ -% |the ducks. To the lions.'' --~\person{Brian Kantor}|\\ -% \end{example} -% -% It's quite simple to use \soul\ commands that way: -% -% \begin{example} -% |\newcommand\comment*{\ul} % or \let\comment=\ul|\\ -% |\sodef\person{\scshape}{0.125em}{0.4583em}{0.5833em}|\\ -% \end{example} -% -% Letterspacing commands like \cs{\so} and \cs{\caps} have to -% check whether they are followed by white space, in which case -% they replace that space by \syn{outer space}. Note that \soul\ -% does look through closing braces. Hence you can conveniently bury -% a \soul\ command within another macro like in the following -% example. Use any other token to hide following space if necessary, -% for example the \cs{\null} macro. -% -% \begin{example} -% |\DeclareRobustCommand*\versal[1]{%|\\ -% | \MakeUppercase{\SOUL@@@versal{#1}}%|\\ -% |}|\\ -% |\sodef\SOUL@@@versal{\upshape}{0.125em}{0.4583em}{0.5833em}|\\ -% \end{example} -% -% -% But what if the \soul\ command is for some reason not the last one -% in that macro definition and thus cannot look ahead at the following token? -% -% -% \begin{example} -% |\newcommand*\somsg[1]{\so{#1}\message{#1}}|\\ -% |...|\\ -% |foo \somsg{bar} baz % wrong spacing after `bar'!|\\ -% \end{example} -% -% In this case you won't get the following space replaced by \emph{outer space} -% because when \soul\ tries to look ahead, it only sees the token -% \cs{\message} and consequently decides that there is no space to replace. -% You can get around this by explicitly calling the space scanner again. -% -% \begin{example} -% |\newcommand*\somsg[1]{{%|\\ -% | \so{#1}%|\\ -% | \message{bar}%|\\ -% | \let\\\SOUL@socheck|\\ -% | \\%|\\ -% |}}|\\ -% \end{example} -% -% However, \cs{\SOUL@socheck} can't be used directly, because it would discard -% any normal space. \cs{\\} doesn't have this problem. -% The additional pair of braces avoids that its definition leaks out -% of this macro. In the example above you could, of course, simply -% have put \cs{\message} in front, so you hadn't needed to -% use the scanner macro \cs{\SOUL@socheck} at all. -% -% Many packages do already offer logical markup commands that default -% to some standard \LaTeX\ font commands or to \cs{\relax}. One example -% is the \package{jurabib} package~\cite{jurabib}, which makes the use of -% \soul\ a challenge. This package implements lots of -% formatting macros. Let's have a look at one of them, \cs{\jbauthorfont}, -% which is used to typeset author names in citations. -% The attempt to simply -% define |\let\jbauthorfont\caps| fails, because the macro isn't directly -% applied to the author name as in |\jbauthorfont{Don Knuth}|, but -% to another command sequence: |\jbauthorfont{\jb@@author}|. Not even -% \cs{\jb@@author} contains the name, but instead further commands that -% at last yield the requested name. That's why we have to expand -% the contents first. This is quite tricky, because we must not -% expand too much, either. Fortunately, we can offer the contents -% wrapped up in yet another macro, so that \soul\ knows that it has to -% use its own macro expansion mechanism: -% -% \begin{example} -% |\renewcommand*\jbauthorfont[1]{{%|\\ -% | \def\x{#1}%|\\ -% | \caps\x|\\ -% |}}|\\ -% \end{example} -% -% Some additional kerning after |\caps\x| wouldn't hurt, because -% the look-ahead scanner is blinded by further commands that follow -% in the \package{jurabib} package. Now we run into the next problem: -% cited names may contain commands -% that must not get expanded. We have to register them as special -% command: -% -% \begin{example} -% |\soulregister\jbbtasep{0}|\\ -% |...|\\ -% \end{example} -% -% But such registered commands bypass \soul's kernel and we don't -% get the correct spacing before and afterwards. So we end up -% redefining \cs{\jbbtasep}, whereby you should, of course, use -% variables instead of numbers: -% -% \begin{example} -% |\renewcommand*\jbbtasep{%|\\ -% | \kern.06em|\\ -% | \slash|\\ -% | \hskip.06em|\\ -% | \allowbreak|\\ -% |}|\\ -% \end{example} -% -% Another problem arises: bibliography entries that must not get -% teared apart are supposed to be enclosed in additional braces. -% This, however, won't work with \soul\ because of -% \ref{par:Grouping hyphenatable material}. A simple trick will -% get you around that problem: define a dummy command that only -% outputs its argument, and register that command: -% -% \begin{example} -% |\newcommand*\together[1]{#1}|\\ -% |\soulregister\together{1}|\\ -% \end{example} -% -% Now you can write ``|Author = {\together{Don Knuth}}|'' and -% \package{jurabib} won't dare to reorder the parts of the name. -% And what if some name shouldn't get letterspaced at all? Overriding -% a conventional font style like \cs{\textbf} that was globally -% set is trivial, you just have to specify the style that you -% prefer in that very bibliography entry. In our example, if we -% wanted to keep \soul\ from letterspacing a particular entry, -% although they are all formatted by our \cs{\jbauthorfont} -% and hence fed to \cs{\caps}, we'd use the following construction: -% -% \begin{example} -% |Author = {\soulomit{\normalfont\huge Donald E. Knuth}}|\\ -% \end{example} -% -% The \package{jurabib} package is probably one of the more -% demanding packages to collaborate with \soul. Everything else -% can just become easier. -% -% -% -% -% -% -% -% -% \subsection{Typesetting long words in narrow columns} -% \label{sec:sloppyword} -% -% Narrow columns are best set |flushleft|, because not even the best -% hyphenation algorithm can guarantee acceptable line breaks without -% overly stretched spaces. -% However, in some rare cases one may be \emph{forced} to typeset -% block aligned. When typesetting in languages like German, where -% there are really long words, the \describemacro{\sloppyword} macro -% might help a little bit. It adds enough stretchability between the -% single characters to make the hyphenation algorithm happy, but -% is still not as ugly as the example in section~\ref{sec:dirtytricks} -% demonstrates. In the following example the left column was typeset -% as ``|Die \sloppyword{Donau...novelle} wird ...|'': -% -% \begin{center} -% \def\word{Do\-nau\-dampf\-schiff\-fahrts\-ge\-sell\-schafts\-^^A -% ka\-pi\-t\"ans\-wit\-wen\-pen\-si\-ons\-ge\-setz\-no\-vel\-le} -% \begin{minipage}{1.5in} -% \plainsetup -% Die -% \expandafter\sloppyword\expandafter{\word} -% wird mit sofortiger Wirkung au\ss er Kraft gesetzt. -% \end{minipage} -% \hspace{1em} -% \batchmode -% \begin{minipage}{1.5in} -% \plainsetup -% Die \word\ wird mit sofortiger Wirkung au\ss er Kraft gesetzt. -% \end{minipage} -% \errorstopmode -% \end{center} -% -% -% -% -% -% -% -% \subsection{Using \texorpdfstring{\soul\ }{soul }commands in section headings} -% -% Letterspacing was often used for section titles in the past, -% mostly centered and with a closing period.

It lets a \emph{word scanner} run over the given argument, -% which inspects every token. If a token is a command registered via \cs{\soulregister}, -% it is executed immediately. Other tokens are only counted and trigger some action -% when a certain number is reached (quotes and dashes). Three subsequent `|-|', for example, -% trigger |\SOUL@everyexhyphen{---}|. A third group leads to special actions, -% like |\mbox| that starts reading-in a whole group to protect its contents and let them be -% seen as one entity. All other tokens, mostly characters and digits, are collected in -% a word register, which is passed to the analyzer, whenever a whole word was read in. -% -% The analyzer typesets the word in a 1\,sp ($=\frac1{65536}$\,pt) wide \cs{\vbox}, -% hence encouraging \TeX\ to break lines at every possible hyphenation point. It -% uses the mono-spaced \cs{\SOUL@tt} font (|ectt1000|), so as to avoid any inter-character -% kerning. Now the \cs{\vbox} is decomposed splitting off \cs{\hbox} after \cs{\hbox} -% from the bottom. All boxes, each of which contains one syllable, are pushed onto a -% stack, which is provided by \TeX's grouping mechanism. When returning from the -% recursion, box after box is fetched from the stack, its width measured and fed to the -%``reconstructor''. -% -% This reconstruction macro (\cs{\SOUL@dosyllable}) starts to read tokens -% from the just analyzed word until the given syllable -% width is obtained. This is repeated for each syllable. Every time the engine -% reaches a relevant state, the corresponding driver macro is executed -% and, if necessary, provided with some data. There is a macro that is -% executed for each token, one for each syllable, one for each space etc\null. -% -% The engine itself doesn't know how to letterspace or to underline. It -% just tells the selected driver about the structure of the given argument. -% There's a default driver (\cs{\SOUL@setup}) that does only set the -% interface macros to a reasonable default state, but doesn't really do anything. -% Further drivers can safely inherit these settings and only need to -% redefine what they want to change. -% -% -% -% -% -% \subsection{The interface} -% \label{sec:interface} -% -% \subsubsection{The registers} -% -% The package offers eight interface macros that can be used to define -% the required actions. Some of the macros receive data as macro parameter -% or in special \emph{token} or \emph{dimen} registers. Here is a list of -% all available registers: -% -% \begin{labeling}{\hspace{.36\hsize}} -% \item[\texttt{\string\SOUL@token}] -% This token register contains the current token. It has to be used as |\the\SOUL@token|. -% The macro \cs{\SOUL@gettoken} reads the next token into \cs{\SOUL@token} and -% can be used in any interface macro. If you don't want to lose the old meaning, -% you have to save it explicitly. \cs{\SOUL@puttoken} pushes the token -% back into the queue, without changing \cs{\SOUL@token}. You can only -% put one token back, otherwise you get an error message. -% \item[\texttt{\string\SOUL@lasttoken}] -% This token register contains the last token. -% \item[\texttt{\string\SOUL@syllable}] -% This token register contains all tokens that were already collected for -% the current syllable. When used in \cs{\SOUL@everysyllable}, it -% contains the \emph{whole} syllable. -% \item[\texttt{\string\SOUL@charkern}] -% This dimen register contains the kerning value between the current and the next character. -% Since most character pairs don't require a kerning value to be applied and the -% output in the logfile shouldn't be cluttered with |\kern0pt| it is -% recommended to write |\SOUL@setkern\SOUL@charkern|, which sets -% kerning for non-zero values only. -% \item[\texttt{\string\SOUL@hyphkern}] -% This dimen register contains the kerning value between the current character -% and the hyphen character or, when used in \cs{\SOUL@everyexhyphen}, the -% kerning between the last character and the explicit hyphen. -% \end{labeling} -% -% -% -% -% -% -% \subsubsection{The interface macros} -% -% The following list describes each of the interface macros and which -% registers it can rely on.
