\maketitle
-With the \emph{alphabeta} package, you can write Greek letters ``by name''
-or as literal Unicode characters in both, ``text'' and ``math'' mode. The
-mode determines whether the letters are taken from the text or math font.
-Just like Latin letters, the Greek counterparts are by default italic in
-math mode (capital letters upright without \emph{fixmath} or
-\emph{\href{http://www.ctan.org/pkg/isomath}{isomath}}) and upright in text:
+\begin{abstract}\noindent
+The \emph{alphabeta} package makes the standard macros for Greek letters in
+mathematical mode also available in text mode. This way, you can input Greek
+letters ``by name'' everywhere in the document. The mode determines whether
+the characters are taken from the text or math font.
+With 8-bit TeX and
+\emph{\href{http://www.ctan.org/pkg/greek-inputenc}{greek-inputenc}},
+literal Unicode charactes can also be used in mathematical mode.
+\end{abstract}
-\begin{quote}
- Text: L \Gamma{} l \gamma,
- emphasized text: \emph{L \Gamma{} l \gamma},
- mathematics: $ L \ \Gamma \ l \ \gamma $
-\end{quote}
+% \tableofcontents
-This makes it easy to write a single Greek symbol (like \Psi{} or \mu{}) or
-a \lambda\omicron\gamma\omicron\varsigma{} in non-Greek text as well as
-ISO-conforming formulas with upright symbols for constants like $A =
-\text{\pi} r^2$ (instead of $A = \pi r^2$).\footnote{%
- The \emph{\href{http://www.ctan.org/pkg/isomath}{isomath}} package
- documentation describes more alternatives for upright Greek symbols in
- math mode.}
+\section{Requirements}
+
+The \emph{alphabeta} package depends on
+\emph{\href{textalpha-doc.pdf}{textalpha}} (both are part of
+\emph{\href{http://www.ctan.org/pkg/greek-fontenc}{greek-fontenc}}).
+It can be used under 8-bit TeX as well as XeTeX/LuaTeX (this document is
+typeset with \engine). Depending on the converter and fonts, different
+\hyperref[sec:limitations]{limitations} apply.
+
+The package conflicts with
+\href{http://www.ctan.org/pkg/unicode-math}{\emph{unicode-math}}.
+
+It also fails, if the \texttt{utf8x} input encoding is selected (interface
+to the \href{http://www.ctan.org/pkg/ucs}{\emph{ucs}} package using a
+non-compatible definition of \verb+\DeclareUnicodeCharacter+).
\section{Usage}
Load this package in the preamble of your document (after font and math
setup) with
\begin{verbatim}
- \usepackage{alphabeta}
-\end{verbatim}
-or, if you want to merge symbol variants, with the
-\texttt{normalize-symbols} option:
-\begin{verbatim}
- \usepackage[normalize-symbols]{alphabeta}
+ \usepackage{alphabeta}
\end{verbatim}
+%
+Now you can write a single Greek symbol (like \Psi{} or \mu{}) or
+a \lambda\omicron\gamma\omicron\varsigma{} in non-Greek text as well as
+ISO-conforming formulas with upright symbols for constants
+like $A = \text{\pi} r^2$ (instead of $A = \pi r^2$).%
+\footnote{The
+ \href{http://mirrors.ctan.org/macros/latex/contrib/isomath/isomath.html}%
+ {\emph{isomath} documentation} describes more alternatives for upright
+ Greek symbols in math mode.}
+
+Just like Latin letters, the Greek counterparts are by default italic in
+math mode%
+\footnote{Capital Greek letters are upright in TeX unless a package selects
+the ``ISO'' math-style. See the
+\href{http://mirrors.ctan.org/macros/latex/contrib/isomath/isomath.html}%
+{\emph{isomath} documentation} for a detailled discussion of math-styles.}
+and upright in text:
+\begin{quote}
+ Text: L \Gamma{} l \gamma,
+ mathematics: $ L \ \Gamma \ l \ \gamma $
+\end{quote}
+%
See the source of this document \url{alphabeta-doc.tex} for a setup and
usage example.
-\subsection{option normalize-symbols}
-The \texttt{normalize-symbols} option is passed to the
-\href{alphabeta-doc.pdf}{\emph{alphabeta}} package. It
-merges ``letters'' and ``symbol`` variants of some Greek
-letters to the ``letter'' character (but is ignored with Unicode fonts):
-\begin{quote}
- This text uses both variants for beta (β|ϐ), theta (θ|ϑ), phi (φ|ϕ), pi
- (π|ϖ), kappa (κ|ϰ), rho (ρ|ϱ), Theta (Θ|ϴ), and epsilon (ε|ϵ) in the LaTeX
- source.
-\end{quote}
+\subsection{options}
+Package options are passed to the \href{alphabeta-doc.pdf}{\emph{alphabeta}}
+package. Example call with options:
+
+\begin{verbatim}
+ \usepackage[normalize-symbols,keep-semicolon]{alphabeta}
+\end{verbatim}
+
+\texttt{normalize-symbols} merges ``letters'' and ``symbol`` variants of
+some Greek letters to the ``letter'' character:
+\footnote{The normalize-symbols option was added in version 0.13 (2015-08-03).
+ Unicode input of the symbol variants requires at least version~1.6
+ (2015-08-05) of
+ \emph{\href{http://www.ctan.org/pkg/greek-inputenc}{greek-inputenc}}.}
+Without this option, the symbol variant characters cannot be used in text,
+because they are not supported by 8-bit Greek fonts (LGR encoding).
+The \texttt{normalize-symbols} option is ignored, if you compile the
+document with XeTeX or LuaTeX using Unicode fonts.
\textbf{Attention}: Be careful in cases where the distinction between the
symbol variants may be important (e.g. in a mathematical or scientific
context). Use XeTeX/LuaTeX with Unicode fonts or the respective characters
-in math mode (e.g. $π$ vs. $ϖ$).
+in mathematical mode (e.g. $\pi$ vs. $\varpi$).
+
+The option \texttt{keep-semicolon} prevents conversion of the semicolon to
+an \emph{ano teleia} (see \emph{\href{textalpha-doc.pdf}{textalpha-doc}}).
+
+\subsection{symbol variants}
+
+Mathematical notation uses variant shapes of some Greek letters as
+additional symbols. The variations have no syntactic meaning in Greek text
+and text fonts may use the variant shapes in place of the “regular” ones as
+a stylistic choice.
+
+Unicode defines separate code points for the symbol variants. TeX supports
+some of the variant shape symbols in mathematical mode, but its concept of
+“standard” vs. “variant” symbols differs from the distinction between
+“GREEK LETTER ...” vs. “GREEK ... SYMBOL” in the Unicode standard.
+See \href{greek-euenc-doc.pdf}{greek-euenc-doc}.
+
+The \emph{alphabeta} package defines generic macros for these variants that
+are short forms of the set defined in \texttt{greek-euenc.def}:
+\begin{quote}
+ \verb|\<name>| selects the Unicode GREEK LETTER ... variant,
+
+ \verb|\<name>symbol| selects the Unicode
+ GREEK ... SYMBOL variant,
+
+ \verb|\var<name>| selects the variant
+ shape according to TeX' mathematical mode
+\end{quote}
+See Table \ref{tab:symbol-variant-macros} for the full list.
+
+\section{Limitations \label{sec:limitations}}
+
+With 8-bit TeX, the limitations described in the
+\href{textalpha-doc.pdf}{textalpha documentation} apply. See also the tests
+in section \hyperref[sec:8-bit-limitations]{8 bit limitations}.
+
+With XeTeX/LuaTeX and Unicode fonts, literal Unicode characters cannot be
+used in formulas (the log file reports missing characters)
+This is a generic TeX limitation which \emph{alphabeta} overcomes if used
+under 8-bit TeX. Under XeTeX/LuaTeX it may be lifted using the
+\href{http://www.ctan.org/pkg/unicode-math}{\emph{unicode-math}}
+package, but unfortunately, \emph{alphabeta} conflicts
+with \emph{unicode-math}.
