The main advantage over these packages is that automatic +% hyphenation is provided for the Greek language. Notice, however, that +% a \TeX\ program with the so-called \eTeX\ extensions is required. +% +% The implementation is available for \LaTeXe\ only; there are no +% corresponding macro files for plain~\TeX\ or \LaTeX~2.09. +% +% +% \section{{\boldmath Why \eTeX?}} +% With `ordinary' \TeX, +% hyphenation of Greek words will not work properly, if the end of a mixed Greek +% and Latin-alphabet paragraph does not coincide with the end of the +% Greek. This is due to a misfeature in \TeX: Only one set of +% so-called lccodes is used throughout the length of a paragraph -- only +% those which are valid at its end. These codes must be adjusted for +% the Ibycus notation in order to tell \TeX\ that accents and breathings +% a part of the words, rather than punctuation. So if you have reverted back +% to a Latin-written language at the end of the paragraph, the wrong +% codes for Greek hyphenation are in effect, and the diacritics in Greek words +% are wrongly considered as punctuation. +% The problem does, however, \emph{not} occur with an \eTeX\ program; i.e., a +% \TeX\ program with certain extended capabilites. In fact, you are +% probably already using \eTeX, even if you did not realize it. +% All up-to-date \LaTeX\ systems are now built upon an \eTeX\ typesetting +% engine, rather than on the classical \TeX\ program. +% +% \section{Usage} +% The Ibycus fonts are assigned a (pseudo-)language named |ibycus|, +% which can be used (almost) like any other language supported by +% Babel. To enable the use of this language in your document, specify +% it as an option to the Babel package just as you would do for any +% other language. For instance, to write a document in German with +% some Greek passages: +% \begin{verse} +% |\usepackage[ibycus,ngerman]{babel}| +% \end{verse} +% +% A few caveats: Do not declare |ibycus| as the default +% language of the document; it is not suitable for this purpose! +% In other words, |ibycus| must never be the last option for Babel. +% And, of course, do not use it together with the packages |ibycus4| +% or |psibycus|. +% +% The language |ibycus| should be selected only locally. Either use +% the |ibycus| environment +% to typeset larger passages of Greek text: +% \begin{verse} +% |\begin{ibycus} | \\ +% | (Hrodo'tou Qouri'ou i(stori'hs a)po'decis h('de, | \\ +% | ... | \\ +% | h(`n ai)ti'hn e)pole'mhsan a)llh'loisi. | \\ +% |\end{ibycus} | +% \end{verse} +% or use the command |\ibygr|, which is more appropriate for +% short pieces of Greek within Latin-written text: +% \begin{verse} +% |blah blah \ibygr{a)rxai=a gra'mmata} blah...| +% \end{verse} +% In fact, the environment |ibycus| is nothing but an abbreviation for +% Babel's |otherlanguage| environment with the option |ibycus|, and +% |\ibygr{...}| is the same as |\foreignlanguage{ibycus}{...}|. +% +% Within the environment |ibycus| or the argument of |\ibygr|, +% the Ibycus-specific input notation is to be used to enter Greek. This +% notation is described in the documentation that comes with the Ibycus +% fonts. +% +% The typeface Ibycus and the related input notation can also be +% selected without changing the hyphenation tables; to do so, use the +% declaration |\ibycustext| or the text-generating command +% |\textibycus{...}|. These macros exist more or less only as a +% side-effect of the implementation; they should normally not be +% needed. +% +% To switch temporarily back to the Latin alphabet within a piece of +% Greek text (without, however, changing the hyphenation table), use +% the declaration |\latintext| or the text-generating macro +% |\textlatin{...}|. When Babel is loaded with the option |ibycus|, +% these commands not only switch back to the default latin text font +% encoding as usual; they also select the default roman font family +% (just like |\rmfamily| or |\textrm|). +% +% Notice a particular difference between |ibycus| and other languages +% of the Babel system: Switching to the language |ibycus| selects +% both a particular font encoding (|U|) and a particular font family (|fib|), +% regardless of the font family that was active before. +% +% The Ibycus typeface provides a few traditional text-editor symbols +% for critical editions: +% +% \begin{center} +% \begin{tabular}{ll} +% \verb+\braceleft + & left curly brace \\ +% \verb+\braceright + & right curly brace\\ +% \verb+\bracketleftbt + & left half square bracket\\ +% \verb+\bracketrightbt+ & right half square bracket\\ +% \verb+\sdagger + & single dagger\\ +% \verb+\dbldagger + & double dagger\\ +% \end{tabular} +% \end{center} +% Use of these symbols is not restricted to Greek +% passages. \textbf{Caution:} +% In the Ibycus4 package the single dagger carries the name |\dagger|. +% However, this macro belongs to the \LaTeX\ kernel and should not be redefined, +% so the name |\sdagger| is now used for the Ibycus-specific symbol. +% +% \section{Scaling the Ibycus fonts} +% The Ibycus typeface was primarily designed to go with Computer Modern; +% yet it can be used with other Latin typefaces, too. In this case it +% may sometimes be useful to typeset the Ibycus fonts a little bit larger +% or smaller, to make them blend better with the Latin typeface. +% This can be accomplished through the macro |\setgreekfontsize|. For instance, +% |\setgreekfontsize{1.05}| will enlarge the Ibycus fonts by 5\%, as compared +% with their nominal size. The command can be issued in the preamble only. +% +% +% \section{The hyphenation patterns} +% The hyphenation patterns for the Ibycus encoding were +% generated by running the Perl script \path{ibyhyph.pl} on +% Dimitrios Filippou's \path{GRAhyph4.tex}, which can be found in the +% CTAN directory \path{language/hyphenation/elhyphen}. This is an +% improved set of hyphenation patterns for ancient Greek with LGR encoding; +% Babel does not currently use it by default. +% +% Dimitrios Filippou's improved hyphenation patterns discover far more +% hyphenation points than the default Babel patterns, and are more +% accurate, especially for compound words. +% You will notice that there are more hyphenation +% points right after the first letter of words beginning +% with a vowel + consonant + vowel. Some may find such hyphenations +% surprising, but they are legal, according to the rules for hyphenation +% of Greek, ancient and modern; see the account by Yannis Haralambous: +% `From Unicode to Typography, a Case Study: the Greek Script' +% \path{<http://omega.enstb.org/yannis/pdf/boston99.pdf>}, pp~18f. +% If you find these hyphenation points ugly, issue the command +% \begin{verse} +% |\def\ibycushyphenmins{2 2}| +% \end{verse} +% after loading of Babel in order to suppress them. +% +% Filippou's patterns also include legal hyphenation points +% immediately before the last letter of a word. However, the +% Ibycus-Babel interface suppreses them, since they are not only ugly +% but also of little practical use. +% +% Please contact Peter Heslin if you come across any words that +% Ibycus hyphenates differently from the corresponding LGR-encoded +% patterns (except for the suppressed hyphenation before the last +% letter of a word). +% +% +% \section{Problems and deficiencies} +% \begin{itemize} +% \item After a sequence such as +% \begin{verse} +% |\selectlanguage{ibycus}| \\ +% \textit{Greek text\dots} \\ +% |\selectlanguage{|\textit{anything}|}| \\ +% \end{verse} +% the font family is changed to the default roman typeface, +% just as after |\rmfamily|. This can be avoided by selecting +% the language |ibycus| only within a group or environment, +% or by using the commands |\ibygr| or |\foreignlanguage|. +% \item The command |\setgreekfontscale| has no effect +% when the Ibycus fonts are already in use; +% this situation is, however, rather unlikely in the preamble. +% \end{itemize} +% +% +% \section{Changes since version 1.5} +% The names of several commands and environments have been changed: +% +% \begin{center} +% \begin{tabular}{ll} +% Version 1.5: & Version 2.4 \\ \hline +% \cmd{\gk} & \cmd{\ibygr} \\ +% \texttt{greek} (environment) & \texttt{ibycus} \\ +% \cmd{\ibylatintext} & \cmd{\latintext} \\ +% \cmd{\dagger} & \cmd{\sdagger} +% \end{tabular} +% \end{center} +% Furthermore, hyphenation before the last letter of a word is now +% suppressed by default. +% +% \StopEventually{} +% +% +% \section{The Implementation} +% \subsection{The \texttt{.ldf} file for use with babel} +% +% When the \TeX\ engine used is not an \eTeX, we issue an appropriate warning: +% \begin{macrocode} +%<*ibycus> +\ifx\eTeXversion\@undefined + \PackageError{ibycus-babel}{% + The TeX engine used by LaTeX \MessageBreak + does not provide the the eTeX extensions.\MessageBreak + This may cause wrong hyphenation\MessageBreak + in mixed Latin/Greek paragraphs} + {Proceed, with fingers crossed...} +\fi +% \end{macrocode} +% +% The macro |\LdfInit| takes care of preventing that this file is +% loaded more than once: +% \begin{macrocode} +\LdfInit{ibycus}{captionsibycus} +% \end{macrocode} +% When this file is read as an option, i.e., by the |\usepackage| +% command, \texttt{ibycus} could be an `unknown' language in +% which case we have to make it known.
