Latin characters in the source are % instead interpreted as a transcription for Greek symbols. % The commands |\greektext| and |\latintext| can be used to switch % to Greek or Latin font encodings but do not change the active language. % 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{Usage} % % To activate Greek support with babel, specify the option % \Lopt{greek}, either as global option or as option to the % \pkg{babel} package. Remember, that the \emph{last} language % option determines the document language, e.g. % \begin{verbatim} % \usepackage[greek,english]{babel}\end{verbatim} % activates support for Greek in an English document while % \begin{verbatim} % \usepackage[english,greek]{babel} % \languageattribute{greek}{polutoniko}\end{verbatim} % sets the document language to Greek with ``polytonic'' % spelling of auto-generated strings. % % For backwards compatibility, ``polytonic'' spelling can also be % selected via the dummy language \Lopt{polutonikogreek}. In this % case, the language name \Lopt{polutonikogreek} must also be % used for language switches with |\selectlanguage| or % |\foreignlanguage|. However, it is not possible to use % both options, \Lopt{greek} and \Lopt{polutonikogreek} in one document. % % \subsubsection{Input of Greek text} % % There are several alternatives for input of Greek text. % The required package \pkg{greek-fontenc} defines % \emph{LaTeX internal character representation} (LICR) macros % for Greek letters and text symbols. % With the packages \pkg{inputenc} and \pkg{greek-inputenc}, % Greek characters can be input using the utf-8, iso-8859-7, % or macgreek encoding. The file \file{usage.pdf} explains a Latin % transliteration defined by the LGR font encoding. % % \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{} % % \subsection{Implementation} % % 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.
