The same character `s' will print as +`$c$' or `$s$', depending on its position in a word. + +\begin{TeXystuff} +The system does this by accessing a ligature of `s' with any other +letter that follows it. If, for some reason, you want to print +an initial/medial sigma by itself (as in the table above), or +at the end of a word, you should type `c'. +\end{TeXystuff} + +Try to typeset some simple text now. Create a file +containing the following lines: + +\begin{quote} +\begin{verbatim} +\documentclass{article} +\usepackage{lgreek} +\begin{document} +This is English text. +\begin{greek} +This is Greek text. +\end{greek} +\end{document} +\end{verbatim} +\end{quote} + +When you \TeX\ this file, you get the following gibberish: +\begin{quote} +%\hbox{ +This is English text. +\begin{greek} +This is Greek text. +\end{greek} +%} +\end{quote} + +If you give the |delims| option for the package then +the character |$| can be used +in place of both |\begin{greek}| and |\end{greek}|, +as eg +\begin{quote} +\begin{verbatim} +This is English text. +$This is Greek text.$ +\end{verbatim} +\end{quote} + +The control sequences |\(|\dots|\)| are still available +for in-text math. + +\section{Accents and Breathings} + +To get an acute, grave or circumflex accent over a vowel, +type |'|, |`| or |~|, respectively, before the vowel. +To get a rough or smooth breathing, type |<| or |>| before +the vowel (or rho) and any accent that it may have. To get an iota +subscript, type \verb"|" \emph{after} the vowel. A diaeresis is +represented by |"|, and if accompanied by an accent it can come +before or after the accent. + +For example, \hbox{\verb">en >arq\~h| >\~hn en >arq~h| >~hn agap\~w}| gives \hbox{$\texttt{s''>agap~w}$}. (Try it.) +On the other hand, there are no ``italic'' or slanted Greek fonts, +so |\it| and |\sl| will give you the same fonts as outside +Greek mode. The various constructions under +%\AMSTeX\ and \LaTeX\ for increasing or decreasing point sizes don't +\LaTeX\ for increasing or decreasing point sizes don't +work yet; they will in a future release. + +The characters that form diacritics (|<|, |>|, +|'|, |`|, |\~|, |"| and \verb"|") are treated differently +depending on whether or not you're in Greek mode. More exactly, +under plain \TeX\ these characters (with the exception of +|\~|) have a |\catcode| of 12: they print as themselves, +and they cannot appear in control words. But in Greek mode +|'|, |`|, |\~|, |"| and \verb"|" are ``letters'', that is, +they have a |\catcode| of 11, while |<| and |>| are +active, with a |\catcode| of 13. This may be important even +for beginners because it means that |'|, for example, can be taken +as part of a control word. Thus the sequence +\begin{verbatim} + \begin{greek} + wm'ega\hfil'alfa + \end{greek} +\end{verbatim} +\noindent +will cause an error message about an +undefined control sequence |\hfil'alfa|, instead of printing +\begin{quote} +\begin{greek} +wm'ega\hfil 'alfa +\end{greek} +\end{quote} +as you might expect. (I hope classicists will forgive this use +of the modern Greek one-accent system.) The solution, of course, +is to remember to add a blank after the |\hfil|. + +\begin{TeXystuff} +A more subtle problem arises when you use Greek text in macro +arguments, if the arguments are scanned while you're outside Greek +mode. This is because \TeX\ assigns |\catcode|s to tokens +as it first reads them, so when the argument is plugged into +the body of the macro the characters above have the wrong +|\catcode|. If the legendary Jonathan Horatio Quick were +to write +\begin{quote} +\begin{verbatim} +\def\hellenize#1{\begin{greek}#1\end{greek}} +\hellenize{d'uo >`h tre~is,} +\end{verbatim} +\end{quote} +he would be unpleasantly surprised by the following output: +\begin{quote} +\def\hellenize#1{\begin{greek}#1\end{greek}} +\hellenize{d'uo >`h tre~is,} +\end{quote} +\enlargethispage{24pt} +which can be explained as follows: the |\~|, which should be +a letter, is seen as an active character, and expands to a blank +as in plain \TeX; while the breathing, which should be active, +is not, and in particular it doesn't do the right thing when +next to the grave accent. Solutions to this problem require a +bit of wizardry, and will not be discussed here; see, for example, +Reinhard Wonneberger's article in the October, 1986 issue of +{\it TUGboat}, especially pages 179--180. +\end{TeXystuff} + +\end{document} + -- cgit v1.2.3
