MacKay + Department of Classics + University of Washington + mackay@cs.washington.edu + + Walter Schmidt + w-a-schmidt@gmx.net + + +Overview +--------- + +Like its predecessors, Ibycus4 is based on Silvio Levy's +realization of a classic Didot cut of Greek type from around 1800. +Ibycus4 is as close as possible to Ibycus3 in all possible +respects, but there are some improved set widths and pair-kernings +which might clobber old carefully adjusted text spacings +such as Alexandrian shaped poetry. + + +Plain TeX usage +--------------- + + \input ibycus4 % to use MF fonts, at fixed sizes +or + \input ibycusps % to use scalable Type1 fonts + +then + \setgreek10/12 (or other reasonable combination + of pointsize and leading) +then + Latin text \GK{}a)rxai=a gra'mmata\RM{} Latin again. + +NOTE that the ) is a smooth breathing, not a parenthesis. + + + +LaTeX2e usage +------------ + + \usepackage{ibycus4} % to use MF fonts, at fixed sizes +or + \usepackage{psibycus} % to use scalable Type1 fonts +then + Latin text {\greek{}a)rxai=a gra'mmata} Latin again. + +Note the outer braces to keep the font change local. +Alternatively, use the text-generating command \textgreek, +which was introduced with version 4.5: + + Latin text \textgreek{a)rxai=a gra'mmata} Latin again. + +Greek text will honor size-changing commands as well as +switching to the bold font series (\bfseries, \textbf}. + + + +LaTeX2e usage with Babel +------------------------ +Alternatively, the Ibycus fonts can be used in LaTeX via the +Babel system. Beside the Babel core, which is part of any +LaTeX system, this requires the macros of the "Ibycus-Babel" +iterface; see + + <CTAN:fonts/greek/package-babel/ibycus-babel/>. + +In contrast to the macros distributed with the fonts, this +newer approach supports proper hypehantion in Greek text +passages. + + + +The TeX macro files and the input conventions +--------------------------------------------- + +$TEXMF/tex/generic/ibycus4/ibycus4.tex + + The main package file for plain TeX + +$TEXMF/tex/generic/ibycus4/ibycusps.tex + + Ditto, using tne Type1 fonts + +$TEXMF/tex/generic/ibycus4/ibycus4.sty + + The main package file for LaTeX 2e + +$TEXMF/tex/generic/ibycus4/psibycus.sty + + Ditto, using the Type1 fonts + +$TEXMF/tex/generic/ibycus4/setiby4.tex + + Included by ibygrk.tex unless newnep format is running + +$TEXMF/tex/generic/ibycus4/pssetiby.tex + + ditto, using the Type1 fonts + +$TEXMF/tex/generic/ibycus4/tlgsqq.tex + + The name suggests the association with coding of the + Thesaurus Linguae Graecae. + + This file provides uniquely named macros for all combinations + of letter and accent, so that any invocation of the macro will + produce a sequence of characters corresponding with the + entries put into the TFM ligature table. These sequences may + always be used to generate accented characters. They are + based, with some slight modifications where David Packard's Ibycus + input coding seems too misleading, on the Ibycus adaptation of + TLG beta-code. + + For input coding, the parentheses, ) and ( are used for + breathings, ' (ASCII char '047--acute or single quote) and ` + (ASCII char '140--grave) are used for oxytone and barytone (to + avoid preemption of the usual TeX excape character) and = + (ASCII char '075) is used for perispomenon to avoid preemption + of the active tie character in plain.tex. + is used for + dieresis after u or i and for some other special characters. + | is used for iota subscript and ! (ASCII char '041--\bang) is + used to call out the "dot-under" convention for partially + preserved letters in manuscript or epigraphical texts. Order + is significant. Breathings or diereses come first, after the + affected letter, then accents, then iota subscript or \bang. + These codings represent the input coding convention, not the + mapping in the font itself. + + The digraphs, trigraphs etc. can be read from tlgsqq.tex + Postpositives fall into three order-dependent and + exclusive classes--only one from each class may be used + in any single accented cluster. + + 1 2 3 + nil nil nil + ( [asper] ' [oxytone] | [iota subscript] + ) [lenis] ` [barytone] !

(The Ibycus system + developed by David Packard is only indirectly named after + the poet. The direct inspiration was Packard's cat.) + +Note that the LaTeX2e exampls use the "traditional" Ibycus +macros, rather than the newer Ibycus-Babel interface. + + + +The METAFONT files +------------------ + +The METAFONT part of the package consists of a set of files which use +the original characters of Silvio Levy's greek fonts and combine them +in ways which reflect the increased capabilities of TeX and METAFONT +developed since Levy did the original greek for TeX. The Levy source +files can be got from one of the CTAN archives and placed in +$TEXMF/fonts/source/public/levy + where they will automatically become +accessible if you are using a TeX Directory Structure [TDS] layout of +files. If you are not using a file searching system like Karl Berry's +"kpathsea", see $TEXMF/fonts/source/public/ibycus4/ibycus4.mf for +hints on making the Levy source available. For directions on the +use and management of Karl Berry's path searching, consult "The TeX +Live Guide, version 2" by Sebastian Rahtz and Michael Goosens, in +{\it TUGboat}. Volume 18 (1997). Pages 81-112, especially pp. 87--9. +Web2c TeX for Unix systems, Thomas Esser's teTeX, and the Solaris package +referenced at http://smc.vnet.net/solaris_2.5.html all use Karl +Berry's path searching. + +Ibycus4 METAFONT files are in $TEXMF/fonts/source/public/ibycus4 + +The most significant changes are: + + 1. The large repertory of initial/medial sigma + letter pairs + is suppressed from the new fonts, and the new enhanced TFM + ligature scheme is used instead to provide for the automatic + differentiation between medial and final sigma. + + 2. The cells thus opened up in the font mapping are used for + a variety of additional characters: + + a. A full repertory of vowels with breathings and + barytone accents (many of these were absent from the + original). The various forms of long epsilon and + omicron with perispomene accent needed for early Attic + and similar local scripts are provided. + + b. Lunate sigma, digamma, koppa and sampi are + provided (the last in its lowercase late form + only, since earlier forms are rather problematic + and are virtually unused even in epigraphical texts). + + c. A simple iota subscript in a 0.5em character space + is provided at position '174 for use in unusual + groupings. For all normal usages three additional + occurences of the glyph are kerned (in the traditional + sense) far to the left so that they will fit under + alpha, eta and omega respectively. These characters + are called out automatically through the TeX TFM + ligature system, for which see below. The glyph under + eta is shortened slightly to give better clearance + under the left stem of lowercase eta. The iota + subscript glyph retains its simple form in 300dpi + renditions, and in any bitmap which drops below + 500dpi, but it thins out and develops a slight + rightward hook at 600dpi and above. + + d. The mechanism of drastic left kerning is also used + to set dots under letters which cannot be read + completely from the manuscript or stone. These dota + are likewise called out automatically through the TFM + ligature system. A final ! {\bang} after any letter + or letter with postpositive accents (except those + with iota subscripts) will produce the dotted form. + + e. Angle brackets, half brackets, double quotes, braces, + a dagger and a doubledagger are now provided (see + iby4extr.tex). + + 3. All characters have been named. The constructs + ASCII"A" and oct"000" appear only at lower levels + of programming. + + 4. Character spacing has been adjusted through kerning tables, + particularly around lowercase iota (file ibylig4.mf). + There is better separation between breathings and accents + (this has required a redesign of almost all accents) and + clearance between accent and base letter has been increased. + The perispomene has been restored to its traditional form with + a thick center and tapered ends, and the breathings have been + given shorter, tapered tails. The deep ink trap between the + bulb and tail of the breathings has been eliminated. Accents + over epsilon have been raised and slightly shortened to give + better clearance. The accents with diaeresis have been shifted + up and laterally to clear the dot they lean toward. + + 5. Font mapping is specified independently of other + parameters, in a distinct and separate file (file ibycus4.map). + In some cases it may be more effective to remap the font + than to struggle with TeX remapping. + + 6. A programming error which produced the wrong displacement + value with free-standing accents has been corrected. Accents + before uppercase vowels are kerned (in the traditional sense) + out left to a negative left side bearing of about one unit + (1/18em) unit so that their escapement does not leave + excessive space after the preceding word or at the start of a + line. They have also been properly pair-kerned with the + uppercase vowels. + +A new naming convention uses "ibycus4" wherever possible, and +the shorter string "iby4" where that would lead to ambiguity. +some of the individual METAFONT character files are simply +taged with the number 4. 8+3 filename compatibility is preserved. +(under protest and with difficulty). + +The names of PK and TFM files follow Karl Berry's font name convention +( 84 is the encoding for Ibycus 4). + +Foundry Facename Weights Variants Encoding_Variants DesignSize + +f ib [r], b r, o 84 [10], 9, 8 + +fibr84 fibo84 fibb84 + + with METAFONT design-size additions +fibr848 fibo848 fibb848 +fibr849 fibo849 fibb849 + +Driver files for the Bold Oblique variant can be provided but their use +is discouraged. These Didot-derived characters do not stand up well +to either boldfacing or obliqueing, and the combination is quite +unfortunate. The typewriter style originally offered with these +designs is quietly forgotten, although the code for it is still +embedded in Silvio Levy's source. + + +Type1 font files +---------------- + +Type1 font files reside in $TEXMF/fonts/type1/public/ibycus4: + +fibr84.pfb (corresponds to the MF font fibr84) +fibb84.pfb (corresponds to the MF font fibb84) + +There are no Type1 renditions of the 8pt and 9pt fonts yet. + + +License +------- + + Copyright (c) 1992--2004 Pierre A.
