\name{Bringhurst} quotes Frederick \name{Goudy}’s famous +dictum on the topic of letterspacing: \quote{A man who would +letterspace lowercase would steal sheep.}\footnote{\ctay{bh}, +p.~31.} +Likewise other judgements: +\quote{Letter spacing is a form of markup particularly hard +to handle, that only master typographers should get involved +with.}\footnote{\ctay{lt}, p.~126.} +And another: +\quote{Letter spacing is disapproved of in the same way as of +capitals \uprightomiss~.}\footnote{\ctay{roemer}, p.~10.} +This module is partly a reaction on the excellent article the +last quotation was taken from, and partly the endeavour of a +convinced \CONTEXT\ user and letter spacer to replace a number of +kludges already in use with something more consistent. +To be sure, those warnings are grounded in facts and they should +seriously be taken into account before one resorts to +letterspacing. + +Before the advent of \LUATEX\ the implementation of proper letter +spacing in *\TEX\ proved to be extremely difficult. +For instance, the \from [soulpackage] package provides some means +but at the same time severely limits the content passed to +macros. +Nevertheless there are magnificent examples of letterspacing done +right, like the \from [leibnizausgabe] by the Leibniz-Archiv in +Hanover that has been typeset with \smallcaps{EDMAC} and \PDFTEX. +Nowadays the Lua node library removes the technical restrictions +and thus leaves the task of correct letterspacing to the user. +The \te{Letterspace} module for \CONTEXT\ was designed to collect +everything necessary to achieve this and to make it accessible +from one place. + +\chapter{Commands} + +Technically, the \te{Letterspace} module doesn’t do anything +fancy; it just maps some existing \CONTEXT\ macros into a single +setup and lets you define and configure your own derivatives of +it. +The module is supposed to be loaded the regular way: somewhere +before \type{\starttext} should be the line +\starttyping

+\chapter{Applications} + +\section{Precautions} + +\te{Letterspacing} is a dynamic property of a string of text, as +opposed to static font properties that are e.g. italics or slant. +In principle, when applying a letterspacing to text, the current +font is not merely pushed back in favor of another font. +Instead, the way of typesetting the same font is modified by +certain parameters; in the case of the \te{Letterspace} module +these are the \te{kerning} and the \te{interword space}. +Therefore it exclusively depends on the correct adjustment of said +parameters whether the letterspacing will achieve its purpose or +not. +On the other hand, external factors like harmonizing different +typefaces, the font’s design size \etc. are ruled out as possible +influences, which can be a great advantage if for example a font +happens to lack a matching italic face for emphasizing. + +\placefigure [left] {Letterspaced greek small capitals after an + initial in \ctay{mt}, vol.~2.} {% + \externalfigure [bodoni-mt-2-4.jpeg] [width=.45\hsize]% +} +Due to its flexibility and because it poses relatively small +demands on the typesetting environment, thoughtless letterspacing +may easily ruin a product. +Moderate values don’t express how important a particular emphasis +is to the author? Just \ugly{widen the spacing} and no reader +will ever skip over your message \dots. +Sure, everybody will get the cue, though the appearance of the +highlighted text, the paragraph, and possibly the whole page will +certainly be spoilt. +Granted, from this perspective letterspacing might appear to be +too dangerous a tool, only begging for misuse. +But this judgement is premature as letterspacing has in fact a +long tradition and was employed in many outstanding examples of +typography. +Apart from its seductive versatility there are no objections +against letterspacing on a general level, as long as it is +carefully utilized. + +Letterspacing has two prevailing uses: ({\it1}) for emphases and +({\it2}) for spacing capital letters, which is especially +valuable in display situations like for instance the front matter +of books or section headings. +Both come with a set of peculiarities that the typesetter must +consider in order to figure out the appropriate values for the +interword and letter spacings. + +\section{Emphasis} +Documents that require many levels of different emphases are +among the primary targets of letterspacing. +For example, in linguistics an author might wish to distinguish +({\it1}) names of cited authors, ({\it2}) ordinary text emphasis, +({\it3}) inline quoted passages, and ({\it4}) word forms or +etymological roots. +To be sure, this can be accomplished with a mapping like + {\it1}: small capitals, + {\it2}: italics, + {\it3}: quotation marks, and + {\it4}: a slanted face. +But \te{quotation marks} are hard to keep track of, if the enveloped +text exceeds a certain length; also, they disencourage skimming +because the reader always has to check whether the point that +caught his eye might belong to a quotation instead of the main +text. +In various fonts -- mainly sans serif -- \te{slant} cannot easily +be told apart from italics, thus defeating the very purpose of +emphasis, in other fonts it might not be available at all. +\te{Bold face} might seem to be an obvious alternative but even +semi bold weights cause text to stand out from the surrounding +paragraph, diverting the readers attention away from its normal +trail along successive lines. +Besides, the more a text is intermingled with different weights, +the closer it resembles the look of a dictionary.\footnote{% + \ctay{lt}, p.~122 distinguish \te{active} from \te{integrated} + markup. + Semi bold and underling belong to the former, italics and slant + to the latter. + As the effect of letter spacing heavily depends on the + environment, it may count as active when used as the only means + of emphasis. + However, in a “colorful” product with many different layers of + emphasis it might not stick out as much among the others and + thus count as integrated (cf. p.~126).% +} + +\placefigure [left] {Letterspaced italics along normal ones in \ctay{lhs2}} {% + \externalfigure [lhs-2-128.jpeg] [width=.5\hsize]% +} +\indentation After these deliberations the validity of +\te{letterspacing,} including lower case, as a means of emphasis +is already half established. +It beats slant with respect to availability and differentiating +effect. +It is preferable over quotation marks because the emphasized +passage clearly differs from the main font style. +Finally, it triumphs over weight switching as the result is very +close to the mean overall distribution of ink within the text +body. +In the previous graduation of emphasis levels an alternative +involving letter spacing could be as follows: + {\it1}: small caps, + {\it2}: letterspaced text font, + {\it3}: italics, and + {\it4}: letterspaced italics or slants. +Here another convenient feature of letterspacing becomes +apparent: as it is basically a different method of typesetting +the same font it can theoretically be applied on any typeface and +weight. +It follows, that in the foregoing mapping, parts of longer +(italic) quotations may be emphasized as well: + \quote{% + regum timendorum in proprios greges {\uprightslash} + reges in ipsos imperium est \te{Iouis} {\uprightslash} + \te{clari} Giganteo triumpho {\uprightslash} + cuncta supercilio \te{mouentis.}% + } +However, substituting rule {\it2} for {\it3}, the resulting +mapping will be less satisfactory. +As quotations are prone to extending over multiple lines, whereas +normal emphasis rarely spans more than two words, spacing out +the former might lead to the unbalanced appearance of paragraphs. +So best avoid letterspacing in cases where the object possibly +encompasses entire sentences. + +Caution is necessary concerning \te{punctuation} adjacient to the +letterspaced passage. +In contrast to italicized or bold emphasis where an immediately +succeeding punctuation sign is best typeset in the surrounding +main face (e.g. „et {\it tu}, Brute?“), letter spacing may +require the sign to be typeset as part of the emphasis. +The reason for this consists partly in the larger interword +spacing that extends onto the surrounding spaces, and partly also +on the letterspacing itself which would be disrupted by a +tighter-spaced character. +(Bad: \te{O Tite}, tute, \te{Tati}, tibi tanta, \te{tyranne}, tulisti; +good: \te{O Tite,} tute, \te{Tati,} tibi tanta, \te{tyranne,} tulisti.) + +\section{Capital Spacing} +\startbuffer [display:capitals] + \start% + %\setupbodyfont [modern,11pt]% + \setupbodyfont [11pt]% + \framed[ + align=middle, + background=color, + backgroundcolor=gray:2, + offset=1em, + frame=off, + ]{% + \def\teststring{mispavayatsim}% + %\definefontfeature [capitals] [cpsp=yes,kern=yes]% how’s this supposed to work? + \bf% + {\color[gray:7]\WORD\teststring}\par + %{\setff{capitals}\WORD\teststring}\par % why doesn’t this have + %an effect with *any* font? + {\color[gray:8]\subff{kerning}\WORD\teststring}\par + {\color[gray:9]\largecaps{\WORD\teststring}}\par + } + \stop% +\stopbuffer + +\starthangaround{\getbuffer [display:capitals]} +Another natural use of letter spacing is to space out capitals and +small caps, whose legibility suffers with increasing markup +length. +The appearance of capitals can be influenced in various ways, as +demonstrated in the illustration to the left. +In the first row, no modification is applied and the capitals are +placed with full kerning. +Row number two has the kerning removed and thus the distance between +letters increases. +The final row, as the second, lacks kerning and adds +20\,\letterpercent\ letter spacing. +\stophangaround + +As is apparent from the example, the difference in spacing +particularly influences the outcome. +The {\WORD unmodified text} in the first row is packed too +tightly, whereas disabling the kerning results in irregular +widening of the {\subff{kerning}\WORD previously kerned} letters +near the center. +In the third row the sequence looks much better because of +additional \mediumcaps{\WORD letterspacing.} +With some fonts \smallcaps{\sc small capitals} profit from additional +spacing as well, as employed in the section headings of this +document.\reference[suppresskern]{} +The \te{Letterspace} module provides a switch \type{suppresskern} +that, if set to {\it yes}, will disable kerning during +letterspacing. +This option is meant for the special treatment of capitalization +but depending on the font it might equally help when dealing with +emphasis as well. +\placefigure [middle] {Letterspaced capitals constitute a title + page in \ctay{mt}, vol.~1.} {% + \externalfigure [bodoni-mt-1-front.jpeg] [width=.75\hsize]% +} + +\chapter{License} + +Copyright 2011 \te{Philipp Gesang}.
