%
%  \section{The Turkish language}
%
%    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-specific macros for the
%    Turkish language\footnote{Mustafa Burc, {\tt
%    rz6001@rziris01.rrz.uni-hamburg.de} provided the code for this
%    file. It is based on the work by Pierre Mackay}.
%
%    Turkish typographic rules specify that a little `white space'
%    should be added before the characters `{\tt:}', `{\tt!}' and
%    `{\tt=}'. In order to insert this white space automatically these
%    characters are made `active'. Also |\frenhspacing| is set.
%
% \StopEventually{}
%
%    As this file needs to be read only once, we check whether it was
%    read before. If it was, the command |\captionsturkish| is already
%    defined, so we can stop processing. If this command is undefined
%    we proceed with the various definitions and first show the
%    current version of this file.
%
%    \begin{macrocode}
\ifx\undefined\captionsturkish
\else
  \selectlanguage{turkish}
  \expandafter\endinput
\fi
%    \end{macrocode}
%
% \begin{macro}{\atcatcode}
%    This file, \file{turkish.sty}, may have been read while \TeX\ is
%    in the middle of processing a document, so we have to make sure
%    the category code of {\tt @} is `letter' while this file is being
%    read.  We save the category code of the @-sign in |\atcatcode|
%    and make it `letter'. Later the category code can be restored to
%    whatever it was before.
%    \begin{macrocode}
\chardef\atcatcode=\catcode`\@
\catcode`\@=11\relax
%    \end{macrocode}
% \end{macro}
%
%    Now we determine whether the the common macros from the file
%    \file{babel.def} need to be read. We can be in one of two
%    situations: either another language option has been read earlier
%    on, in which case that other option has already read
%    \file{babel.def}, or {\tt turkish} is the first language option
%    to be processed. In that case we need to read \file{babel.def}
%    right here before we continue.
%
%    \begin{macrocode}
\ifx\undefined\babel@core@loaded\input babel.def\relax\fi
%    \end{macrocode}
%
%    Tell the \LaTeX\ system who we are and write an entry on the
%    transcript.
%    \begin{macrocode}
\ProvidesFile{turkish.sty}[1994/06/26 v1.2c
         Turkish support from the babel system]
%    \end{macrocode}
%
%    Another check that has to be made, is if another language
%    specific file has been read already. In that case its definitions
%    have been activated. This might interfere with definitions this
%    file tries to make. Therefore we make sure that we cancel any
%    special definitions. This can be done by checking the existence
%    of the macro |\originalTeX|. If it exists we simply execute it.
%    \begin{macrocode}
\ifx\undefined\originalTeX \let\originalTeX\empty\fi
\originalTeX
%    \end{macrocode}
%
%    When this file is read as an option, i.e. by the |\usepackage|
%    command, {\tt turkish} could be an `unknown' language in which
%    case we have to make it known. So we check for the existence of
%    |\l@turkish| to see whether we have to do something here.
%
% \changes{turkish-1.2c}{1994/06/26}{Now use \cs{@nopatterns} to
%    produce the warning}
%    \begin{macrocode}
\ifx\undefined\l@turkish
  \@nopatterns{Turkish}
  \adddialect\l@turkish0\fi
%    \end{macrocode}
%
%    The next step consists of defining commands to switch to (and
%    from) the Turkish language.
%
% \begin{macro}{\captionsturkish}
%    The macro |\captionsturkish| defines all strings used in the four
%    standard documentclasses provided with \LaTeX.
% \changes{turkish-1.1}{15 jul 93}{`headpagename should be `pagename}
% \changes{turkish-1.2b}{1994/06/04}{Added braces behind \cs{i} in
%    strings}
%    \begin{macrocode}
\addto\captionsturkish{%
  \def\prefacename{Preface}% <-- This needs translation!!
  \def\refname{Ba\c svurulan Kitaplar}%
  \def\abstractname{Konu}%

}%
%    \end{macrocode}
% \end{macro}
%
% \begin{macro}{\dateturkish}
%    The macro |\dateturkish| redefines the command |\today| to
%    produce Turkish dates.
% \changes{turkish-1.2b}{1994/06/04}{Added braces behind \cs{i} in
%    strings}
%    \begin{macrocode}
\def\dateturkish{%
  \def\today{\number\day.~\ifcase\mont\or
    Ocak\or \c Subat\or Mart\or Nisan\or May\i{}s\or Haziran\or
    Temmuz\or A\u gustos\or Eyl\"ul\or Ekim\or Kas\i{}m\or
    Aral\i{}k\fi
    \space\number\year}}
}
%    \end{macrocode}
% \end{macro}
%
% \begin{macro}{\extrasturkish}
% \begin{macro}{\noextrasturkish}
%    The macro |\extrasturkish| will perform all the extra definitions
%    needed for the Turkish language. The macro |\noextrasturkish| is
%    used to cancel the actions of |\extrasturkish|.
%
%    Turkish typographic rules specify that a little `white space'
%    should be added before the characters `{\tt:}', `{\tt!}' and
%    `{\tt=}'. In order to insert this white space automatically these
%    characters are made `active', so they have to be treated in a
%    special way.
%    \begin{macrocode}
\addto\extrasturkish{%
  \babel@add@special\:%
  \babel@add@special\!%
  \babel@add@special\=}
%    \end{macrocode}
%    When |\noextrasturkish| is executed they are no longer `special'.
%    \begin{macrocode}
\addto\noextrasturkish{%
  \babel@remove@special\:%
  \babel@remove@special\!%
  \babel@remove@special\=}
%    \end{macrocode}
%
%    Before the category codes of these characters can be changed ,
%    their current category code needs to be stored, in order to
%    restore them later.
%    \begin{macrocode}
\addto\extrasturkish{%
  \babel@savevariable{\catcode`\:}\babel@save\active@co
  \babel@savevariable{\catcode`\!}\babel@save\active@em
  \babel@savevariable{\catcode`\=}\babel@save\active@es
}
%    \end{macrocode}
%    Now that the category codes are stored we can assign new category
%    codes to these characters.
% \changes{turkish-1.1}{11 jul 93}{When active characters are defined
%    they should be active. Redid the coding.}
%    \begin{macrocode}
\addto\extrasturkish{\catcode`\:\active\catcode`\!\active
                     \catcode`\=\active}
%    \end{macrocode}
%    And they can be defined.
%    \begin{macrocode}
\begingroup
  \catcode`\:\active
  \catcode`\!\active
  \catcode`\=\active
  \def\x{\endgroup
    \addto\extrasturkish{%

      \def={\protect\active@es}\let\active@es\turkish@active@es}}
\x
%    \end{macrocode}
%    For Turkish texts |\frenchspacing| should be in effect. We
%    make sure this is the case and reset it if necessary.
%    \begin{macrocode}

    \addto\noextrasturkish{\nonfrenchspacing}%
  \fi}
%    \end{macrocode}
% \end{macro}
% \end{macro}
%
% \begin{macro}{\turkish@active@co}
% \begin{macro}{\turksih@active@em}
% \begin{macro}{\turkish@active@es}
%    The definitions for the three active characters were made using
%    intermediate macros. These are defined now. The insertion of
%    extra `white space' should only happen outside math mode, hence
%    the check |\ifmmode| in the macros.
%    \begin{macrocode}
\turkish@active@co{\ifmmode\string:\else\relax
    \ifhmode\ifdim\lastskip>\z@
    \unskip\penalty\@M\thinspace\fi\fi\string:\fi}
\def\turkish@active@em{\ifmmode\string!\else\relax
     \ifhmode\ifdim\lastskip>\z@
    \unskip\penalty\@M\thinspace\fi\fi\string!\fi}
\def\turkish@active@es{\ifmmode\string=\else\relax
    \ifhmode\ifdim\lastskip>\z@
    \unskip\kern\fontdimen2\font
     \kern-1.4\fontdimen3\font
    \fi\fi
    \string=\fi}
%    \end{macrocode}
% \end{macro}
% \end{macro}
% \end{macro}
%
%    Our last action is to activate the commands we have just defined,
%    by calling the macro |\selectlanguage|.  Next the \babel{} macro
%    |\selectlanguage| is used to activate the definitions for
%    Turkish.
%    \begin{macrocode}
\selectlanguage{turkish}
%    \end{macrocode}
%    Finally, the category code of {\tt @} is reset to its original
%    value. The macrospace used by |\atcatcode| is freed.
