The original author is Apostolos Syropoulos +% (\texttt{apostolo@platon.ee.duth.gr}), code from +% \file{kdgreek.sty} by David Kastrup +% \texttt{dak@neuroinformatik.ruhr-uni-bochum.de} was used to +% enhance the support for typesetting greek texts.} defines all the +% language definition macros for the Greek language, i.e., +% as it used today with only one accent, and the attribute +% $\pi o\lambda\upsilon\tau o\nu\kappa\acute{o}$ (``Polutoniko'') +% for typesetting greek text with all accents. This separation +% arose out of the need to simplify things, for only very few +% people will be really interested to typeset polytonic Greek +% text. +% +% \DescribeMacro\greektext +% \DescribeMacro\latintext +% The commands |\greektext| and |\latintext| can be used to switch +% to greek or latin fonts. These are declarations. +% +% \DescribeMacro\textgreek +% \DescribeMacro\textlatin +% The commands |\textgreek| and |\textlatin| both take one argument +% which is then typeset using the requested font encoding. +% \DescribeMacro\textol +% The command |\greekol| switches to the greek outline font family, +% while the command |\textol| typests a short text in outline font. +% A number of extra greek characters are made available through the +% added text commands |\stigma|, |\qoppa|, |\sampi|, |\ddigamma|, +% |\Digamma|, |\euro|, |\permill|, and |\vardigamma|. +% +% \subsection{Typing conventions} +% +% Entering greek text can be quite difficult because of the many +% diacritical signs that need to be added for various purposes. +% The fonts that are used to typeset Greek make this a lot +% easier by offering a lot of ligatures. But in order for this to +% work, some characters need to be considered as letters. These +% characters are |<|, |>|, |~|, |`|, |'|, |"| and +% \verb=|=. Therefore their |\lccode| is changed when Greek is in +% effect. In order to let |\uppercase| give correct results, the +% |\uccode| of these characters is set to a non-existing character +% to make them disappear. Of course not all characters are needed +% when typesetting ``modern'' $\mu o\nu o\tau o\nu +% \iota\kappa\acute{o}$. In that case we only need the |'| and |"| +% symbols which are treated in the proper way. +% +% \subsection{Greek numbering} +% +% The Greek alphabetical numbering system, like the Roman one, is +% still used in everyday life for short enumerations. Unfortunately +% most Greeks don't know how to write Greek numbers bigger than 20 or +% 30. Nevertheless, in official editions of the last century and +% beginning of this century this numbering system was also used for +% dates and numbers in the range of several thousands. Nowadays +% this numbering system is primary used by the Eastern Orthodox +% Church and by certain scholars. It is hence necessary to be able +% to typeset any Greek numeral up to \hbox{999\,999}. Here are the +% conventions: +% \begin{itemize} +% \item There is no Greek numeral for any number less than or equal +% to $0$. +% \item Numbers from $1$ to $9$ are denoted by letters alpha, beta, +% gamma, delta, epsilon, stigma, zeta, eta, theta, followed by a +% mark similar to the mathematical symbol ``prime''. (Nowadays +% instead of letter stigma the digraph sigma tau is used for number +% $6$. Mainly because the letter stigma is not always available, so +% people opt to write down the first two letters of its name as an +% alternative. In our implementation we produce the letter stigma, +% not the digraph sigma tau.) +% \item Decades from $10$ to $90$ are denoted by letters iota, +% kappa, lambda, mu, nu, xi, omikron, pi, qoppa, again followed by +% the numeric mark. The qoppa used for this purpose has a special +% zig-zag form, which doesn't resemble at all the original +% `q'-like qoppa. +% \item Hundreds from $100$ to $900$ are denoted by letters rho, +% sigma, tau, upsilon, phi, chi, psi, omega, sampi, followed by the +% numeric mark. +% \item Any number between $1$ and $999$ is obtained by a group of +% letters denoting the hundreds decades and units, followed by a +% numeric mark. +% \item To denote thousands one uses the same method, but this time +% the mark is placed in front of the letter, and under the baseline +% (it is inverted by 180 degrees). When a group of letters denoting +% thousands is followed by a group of letters denoting a number +% under $1000$, then both marks are used. +% \end{itemize} +% +% Using these conventions one obtains numbers up to \hbox{999\,999}. +% \DescribeMacro{\greeknumeral} +% The command |\greeknumeral| makes it possible to typeset Greek +% numerals. There is also an +% \DescribeMacro{\Greeknumeral} +% ``uppercase'' version of this macro: |\Greeknumeral|. +% +% Another system which was in wide use only in Athens, could +% express any positive number. This system is implemented in +% package |athnum|. +% +% \StopEventually{} +% +% The macro |\LdfInit| takes care of preventing that this file is +% loaded more than once, checking the category code of the +% \texttt{@} sign, etc. +% \changes{greek-1.0b}{1996/11/02}{Now use \cs{LdfInit} to perform +% initial checks} +% \begin{macrocode} +%<*code> +\LdfInit\CurrentOption{captions\CurrentOption} +% \end{macrocode} +% When the option \Lopt{polutonikogreek} was used, redefine +% |\CurrentOption| to prevent problems later on. +% \begin{macrocode} +\gdef\CurrentOption{greek}% +% \end{macrocode} +% +% When this file is read as an option, i.e. by the |\usepackage| +% command, \texttt{greek} could be an `unknown' language in +% which case we have to make it known.

The current support for greek uses the |cb| fonts +% created by Claudio Beccari\footnote{Apostolos Syropoulos wishes +% to thank him for his patience, collaboration, cooments and +% suggestions.}. The |cb| fonts provide all sorts of \textit{font +% combinations}. In order to use these fonts we define the Local +% GReek encoding (LGR, see the file \file{greek.fdd}). We make sure +% that this encoding is known to \LaTeX, and if it isn't we abort. +% \changes{greek-1.2a}{1997/10/31}{filename \file{lgrenc.def} now +% lowercase} +% \begin{macrocode} +\InputIfFileExists{lgrenc.def}{% + \message{Loading the definitions for the Greek font encoding}}{% + \errhelp{I can't find the lgrenc.def file for the Greek fonts}% + \errmessage{Since I do not know what the LGR encoding means^^J + I can't typeset Greek.^^J + I stop here, while you get a suitable lgrenc.def file}\@@end + } +% \end{macrocode} +% +% Now we define two commands that offer the possibility to switch +% between Greek and Roman encodings. +% +% \begin{macro}{\greektext} +% The command |\greektext| will switch from Latin font encoding to +% the Greek font encoding. This assumes that the `normal' font +% encoding is a Latin one. This command is a \emph{declaration}, +% for shorter pieces of text the command |\textgreek| should be +% used. +% \begin{macrocode} +\DeclareRobustCommand{\greektext}{% + \fontencoding{LGR}\selectfont + \def\encodingdefault{LGR}} +% \end{macrocode} +% \end{macro} +% +% \begin{macro}{\textgreek} +% This command takes an argument which is then typeset using the +% requested font encoding. In order to avoid many encoding switches +% it operates in a local scope. +% \changes{greek-1.0b}{1996/09/23}{Added a level of braces to keep +% encoding change local} +% \changes{greek-1.3k}{2003/03/19}{Added \cs{leavevmode} as was done +% with \cs{latintext}} +% \begin{macrocode} +\DeclareRobustCommand{\textgreek}[1]{\leavevmode{\greektext #1}} +% \end{macrocode} +% \end{macro} +% +% \begin{macro}{\textol} +% A last aspect of the set of fonts provided with this version of +% support for typesetting Greek texts is that it contains an +% outline family.

In the underlying family of fonts (the +% |cb| fonts) this is solved using Knuth's ligature +% mechanism. +% Characters we need to have ligatures with are the tilde, the +% acute and grave accent characters, the rough and smooth breathings, +% the subscript, and the double quote character. +% In text input the |~| is normaly used to produce an +% unbreakable space. The command |\~| normally produces a tilde +% accent. For polytonic Greek we change the definition of |\~| +% to produce the tilde character itself, making sure it has category +% code 12. +% \changes{greek-1.3k}{2003/04/10}{Make sure the character `!' is not +% active during the definition of \cs{greek@tilde}} +% \begin{macrocode} +\begingroup + \@ifundefined{active@char\string!}{}{\catcode`!=12\relax} + \catcode`\~=12 + \lccode`\!=`\~ + \lowercase{\def\x{\endgroup + \def\greek@tilde{!}}\x} +\addto\extraspolutonikogreek{% + \babel@save\~\let\~\greek@tilde} +% \end{macrocode} +% \end{macro} +% In order to get correct hyphenation we need to set the lower case +% code of a number of characters. The `v' character has a special +% usage for the |cb| fonts: in fact this ligature mechanism detects +% the end of a word and assures that a final sigma is typeset with +% the proper sign wich is different from that of an initial or +% medial sigma; the `v 'after an \textit{isolated} sigma fools +% the ligature mechanism in order to typeset $\sigma$ in place of +% $\varsigma$. Because of this we make sure its lowercase code is +% not changed.
