\title{Greek diacritics with standard accent macros}
\author{G\"unter Milde}
\date{\filedate}
\maketitle
The font encoding definition file \texttt{lgrenc.def} defines LICR macros
for all non-ASCII characters in the LGR font encoding. Greek accent macros
have names starting with \verb|\acc| followed by the Greek accent name as
used in the Unicode standard (e.g. \verb|\acctonos|). The standard symbol
accents \verb|\' \` \~| behave according to Greek typography if used in the
LGR font encoding.
The \emph{textalpha} or \emph{alphabeta} packages define the symbol macros
\verb|\<| and \verb|\>| as alias for the breathings (Dasia and Psili).%
\footnote{The definition of the macros
\texttt{\textbackslash<} and \texttt{\textbackslash>} was moved
from the font definition file \texttt{greek-fontenc.def} to
\texttt{textalpha.sty} in order to avoid clashes with local
definitions of this macros in documents using the LGR font
encoding via \emph{fontenc} or \emph{babel}.}
With these packages, all Greek diacritics can be input as backslash followed
by the LGR transliteration.%
\footnote{This makes it easy to follow the advise in
\emph{teubner-doc}: ``typeset your paper with the regular
accent vowel ligatures and [{\ldots}] substitute them in the
final revision with the accented vowel macros only in those
instances where the lack of kerning is disturbing''.}
The example in babel/contrib/greek/usage.pdf:
%
\begin{quote} \selectlanguage{greek}
T\'i f\'hic? \<Id\`wn \>enj\'ede pa\~id''
\>eleuj\'eran t\`ac plhs\'ion N\'umfac stefano\~usan,
S\'wstrate, \>er\~wn \'ap\~hljec e\>uj\'uc?
\end{quote}
can be input as
\begin{lstlisting}
T\'i f\'hic? \<Id\`wn \>enj\'ede pa\~id''
\>eleuj\'eran t\`ac plhs\'ion N\'umfac stefano\~usan,
S\'wstrate, \>er\~wn \'ap\~hljec e\>uj\'uc?
\end{lstlisting}
%
Improvements over the ligature-based approach in LGR:
%
\begin{itemize}
\item Accents can be placed on any character:
\textgreek{\"k \`l \'m \~<n \<o \>'p \>9 \`\>-}
\item Kerning is preserved
\selectlanguage{greek}
\begin{tabular}[t]{llll}
& \textlatin{roman} & \textlatin{italic} & \textlatin{cbleipzig} \\
\foreignlanguage{british}{accent macro:} &
a\>ut'os & \emph{a\>ut\'os} & \textli{a\>ut\'os} \\
\foreignlanguage{british}{transliteration:} &
a>ut'os & \emph{a>ut'os} & \textli{a>ut'os}\\
\end{tabular}
\selectlanguage{british}
Like in any font encoding, kerning only works with pre-composed glyphs:\\
\textgreek{A\"UA $\ne$ A\~UA}, AVA $\ne$ A\'VA.
\item Compatible with hyperref (see greekhyperref.pdf).
\item Following Greek typesetting convention, diacritics (except the
dialytika) are placed to the left of capital letters and and dropped
by \verb|\MakeUppercase|:
\begin{quote} \selectlanguage{greek}
\'antropos $\mapsto$ \MakeUppercase{\'antropos},
\>'antropos $\mapsto$ \MakeUppercase{\>'antropos},\\
Aqill\'eas $\mapsto$ \MakeUppercase{Aqill\'eas},
\>Aqille\'us $\mapsto$ \MakeUppercase{\>Aqille\'us}.
\end{quote}
The dialytika is printed even in cases where it's not needed
in lowercase: % the "hiatus" feature
\begin{quote} \selectlanguage{greek}
\'aulos $\mapsto$ \MakeUppercase{\'aulos},
\'>aulos $\mapsto$ \MakeUppercase{\'\>aulos},
% from http://diacritics.typo.cz/index.php?id=69 μάινα -> ΜΑΪΝΑ
m\'aina $\mapsto$ \MakeUppercase{m\'aina},\\
% from http://de.wikipedia.org/wiki/Neugriechische_Orthographie#Das_Trema
% κέικ, ἀυπνία/αϋπνία
k\'eik, $\mapsto$ \MakeUppercase{k\'eik},
\>aupn\'ia $\mapsto$ \MakeUppercase{\>aupn\'ia}.
\end{quote}
\end{itemize}
\selectlanguage{british} Composite diacritics can be specified as
named macro, backslash + LGR transliteration, or combined accent macros,
e.\,g. \textgreek{\~>a} can be written as
\begin{quote}
\verb+\accpsiliperispomeni{a}+,
\verb+\~>a+, \verb+\>~a+,
\verb+\~\>{a}+, or \verb+\~\>a+.
\end{quote}
However, braces in composite accents
(\verb+\~{\>a}+, \verb+\~{>a}+, or \verb+\~{\>{a}}+)
lead to errors.
\verb+\MakeUppercase+ works with most input variants but fails with a tilde
in a document which does \textbf{not} define the \texttt{greek} or
\texttt{polutonikogreek} language with Babel (which fixes the uccode for
characters used in the LGR transliteration).
Combining ``symbol macros'' (\verb+\>\~+) or reversing the order
(\verb+\~>+) is safe.
% \foreignlanguage{greek}{\~>a \>~a \>\~a \~\>a $\mapsto$
% \MakeUppercase{\~>a \>~a \>\~a \~\>a}}.
Accent macros can start with \verb|\a| instead of \verb|\| when the
short form is redefined, e.\,g. inside a \emph{tabbing} environment.
This also works for the new-defined Dasia and Psili shortcuts
(\verb|\a<| and \verb|\a>|):
%
\begin{quote}
\selectlanguage{greek}
\begin{tabbing}
T'i f'hic? \= T\a'i f\a'hic? \\
<Id`wn \> \a>enj\a'ede pa\a~id
\end{tabbing}
\end{quote}
\end{document}
