%  \section{The German language -- new orthography}
%
%    The file \file{\filename}\footnote{The file described in this
%    section has version number \fileversion\ and was last revised on
%    \filedate.}  defines all the language definition macros for the
%    German language with the `new orthography' introduced in
%    August 1998.  This includes also the Austrian dialect of this
%    language.
%  
%    As with the `traditional'  German orthography, 
%    the character |"| is made active, and 
%    the commands in  table~\ref{tab:german-quote} can be used, except
%    for |"ck| and |"ff| etc., which are no longer required.
%
%    The internal language names are |ngerman| and |naustrian|.
%
% \StopEventually{}
%
%    When this file was read through the option \Lopt{ngermanb} we make
%    it behave as if \Lopt{ngerman} was specified.
%    \begin{macrocode}
\def\bbl@tempa{ngermanb}
\ifx\CurrentOption\bbl@tempa
  \def\CurrentOption{ngerman}
\fi
%    \end{macrocode}
%
%    The macro |\LdfInit| takes care of preventing that this file is
%    loaded more than once, checking the category code of the
%    \texttt{@} sign, etc.
%    \begin{macrocode}
%<*code>
\LdfInit\CurrentOption{captions\CurrentOption}
%    \end{macrocode}
%
%    When this file is read as an option, i.e., by the |\usepackage|
%    command, \texttt{ngerman} will be an `unknown' language, so we
%    have to make it known.  So we check for the existence of
%    |\l@ngerman| to see whether we have to do something here.
%
%    \begin{macrocode}
\ifx\l@ngerman\@undefined
  \@nopatterns{ngerman}
  \adddialect\l@ngerman0
\fi
%    \end{macrocode}
%
%    For the Austrian version of these definitions we just add another
%    language. 
%    \begin{macrocode}
\adddialect\l@naustrian\l@ngerman
%    \end{macrocode}
%
%    The next step consists of defining commands to switch to (and
%    from) the German language.
%
%  \begin{macro}{\captionsngerman}
%  \begin{macro}{\captionsnaustrian}
%    Either the macro |\captionnsgerman| or the macro
%    |\captionsnaustrian| will define all strings used in the four
%    standard document classes provided with \LaTeX.
%
% \changes{ngermanb-2.6k}{2000/09/20}{Added \cs{glossaryname}}

%
%  \begin{macro}{\datengerman}
%    The macro |\datengerman| redefines the command
%    |\today| to produce German dates.
%    \begin{macrocode}
\def\month@ngerman{\ifcase\month\or
  Januar\or Februar\or M\"arz\or April\or Mai\or Juni\or

    \space\number\year}}
%    \end{macrocode}
%  \end{macro}
%
%  \begin{macro}{\dateanustrian}
%    The macro |\datenaustrian| redefines the command
%    |\today| to produce Austrian version of the German dates.
%    \begin{macrocode}
\def\datenaustrian{\def\today{\number\day.~\ifnum1=\month
  J\"anner\else \month@ngerman\fi \space\number\year}}
%    \end{macrocode}
%  \end{macro}
%
%  \begin{macro}{\extrasngerman}
%  \begin{macro}{\extrasnaustrian}
%  \begin{macro}{\noextrasngerman}
%  \begin{macro}{\noextrasnaustrian}
%    Either the macro |\extrasngerman| or the macros |\extrasnaustrian|
%    will perform all the extra definitions needed for the German
%    language. The macro |\noextrasngerman| is used to cancel the
%    actions of |\extrasngerman|. 
%
%    For German (as well as for Dutch) the \texttt{"} character is
%    made active. This is done once, later on its definition may vary.
%    \begin{macrocode}
\initiate@active@char{"}
\@namedef{extras\CurrentOption}{%
  \languageshorthands{ngerman}}
\expandafter\addto\csname extras\CurrentOption\endcsname{%
  \bbl@activate{"}}
%    \end{macrocode}
%    Don't forget to turn the shorthands off again.
% \changes{ngermanb-2.6j}{1999/12/16}{Deactivate shorthands ouside of
%    German}
%    \begin{macrocode}
\addto\noextrasngerman{\bbl@deactivate{"}}
%    \end{macrocode}
%
%
%    In order for \TeX\ to be able to hyphenate German words which
%    contain `\ss' (in the \texttt{OT1} position |^^Y|) we have to
%    give the character a nonzero |\lccode| (see Appendix H, the \TeX
%    book).
%    \begin{macrocode}
\expandafter\addto\csname extras\CurrentOption\endcsname{%
  \babel@savevariable{\lccode25}%
  \lccode25=25}
%    \end{macrocode}
%
%    The umlaut accent macro |\"| is changed to lower the umlaut dots.
%    The redefinition is done with the help of |\umlautlow|.
%    \begin{macrocode}
\expandafter\addto\csname extras\CurrentOption\endcsname{%
  \babel@save\"\umlautlow}
\@namedef{noextras\CurrentOption}{\umlauthigh}
%    \end{macrocode}
%    The current 
%    version of the `new' German hyphenation patterns (\file{dehyphn.tex}
%    is to be used with |\lefthyphenmin| and |\righthyphenmin| set to~2. 
% \changes{ngermanb-2.6k}{2000/09/22}{Now use \cs{providehyphenmins} to
%    provide a default value}
%    \begin{macrocode}
\providehyphenmins{\CurrentOption}{\tw@\tw@}
%    \end{macrocode}
%    For German texts we need to make sure that |\frenchspacing| is
%    turned on.
% \changes{ngermanb-2.6m}{2001/01/26}{Turn frenchspacing on, as in
%    \texttt{german.sty}}
%    \begin{macrocode}
\expandafter\addto\csname extras\CurrentOption\endcsname{%
  \bbl@frenchspacing}
\expandafter\addto\csname noextras\CurrentOption\endcsname{%
  \bbl@nonfrenchspacing}
%    \end{macrocode}
%  \end{macro}
%  \end{macro}
%  \end{macro}
%  \end{macro}
%
%    The code above is necessary because we need an extra active
%    character. This character is then used as indicated in
%    table~\ref{tab:german-quote}.
%
%    To be able to define the function of |"|, we first define a
%    couple of `support' macros.
%
%
%  \begin{macro}{\dq}
%    We save the original double quote character in |\dq| to keep
%    it available, the math accent |\"| can now be typed as |"|.
%    \begin{macrocode}
\begingroup \catcode`\"12
\def\x{\endgroup
  \def\@SS{\mathchar"7019 }
  \def\dq{"}}
\x
%    \end{macrocode}
%  \end{macro}
%
%    Now we can define the doublequote macros: the umlauts,
%    \begin{macrocode}
\declare@shorthand{ngerman}{"a}{\textormath{\"{a}\allowhyphens}{\ddot a}}
\declare@shorthand{ngerman}{"o}{\textormath{\"{o}\allowhyphens}{\ddot o}}
\declare@shorthand{ngerman}{"u}{\textormath{\"{u}\allowhyphens}{\ddot u}}
\declare@shorthand{ngerman}{"A}{\textormath{\"{A}\allowhyphens}{\ddot A}}
\declare@shorthand{ngerman}{"O}{\textormath{\"{O}\allowhyphens}{\ddot O}}
\declare@shorthand{ngerman}{"U}{\textormath{\"{U}\allowhyphens}{\ddot U}}

%    tremas,
%    \begin{macrocode}
\declare@shorthand{ngerman}{"e}{\textormath{\"{e}}{\ddot e}}
\declare@shorthand{ngerman}{"E}{\textormath{\"{E}}{\ddot E}}
\declare@shorthand{ngerman}{"i}{\textormath{\"{\i}}%
                              {\ddot\imath}}
\declare@shorthand{ngerman}{"I}{\textormath{\"{I}}{\ddot I}}
%    \end{macrocode}
%    german es-zet (sharp s),
%    \begin{macrocode}
\declare@shorthand{ngerman}{"s}{\textormath{\ss}{\@SS{}}}
\declare@shorthand{ngerman}{"S}{\SS}
\declare@shorthand{ngerman}{"z}{\textormath{\ss}{\@SS{}}}
\declare@shorthand{ngerman}{"Z}{SZ}
%    \end{macrocode}
%    german and french quotes,
%    \begin{macrocode}
\declare@shorthand{ngerman}{"`}{\glqq}
\declare@shorthand{ngerman}{"'}{\grqq}
\declare@shorthand{ngerman}{"<}{\flqq}
\declare@shorthand{ngerman}{">}{\frqq}
%    \end{macrocode}
%    and some additional commands:
%    \begin{macrocode}
\declare@shorthand{ngerman}{"-}{\nobreak\-\bbl@allowhyphens}
\declare@shorthand{ngerman}{"|}{%
  \textormath{\penalty\@M\discretionary{-}{}{\kern.03em}%
              \allowhyphens}{}}
\declare@shorthand{ngerman}{""}{\hskip\z@skip}
\declare@shorthand{ngerman}{"~}{\textormath{\leavevmode\hbox{-}}{-}}
\declare@shorthand{ngerman}{"=}{\penalty\@M-\hskip\z@skip}
%    \end{macrocode}
%
%  \begin{macro}{\mdqon}
%  \begin{macro}{\mdqoff}
%    All that's left to do now is to  define a couple of commands
%    for reasons of compatibility with \file{german.sty}.
%    \begin{macrocode}
\def\mdqon{\shorthandon{"}}
\def\mdqoff{\shorthandoff{"}}
%    \end{macrocode}
%  \end{macro}
%  \end{macro}
%
%    The macro |\ldf@finish| takes care of looking for a
%    configuration file, setting the main language to be switched on
%    at |\begin{document}| and resetting the category code of
%    \texttt{@} to its original value.
