%
%    This file is part of the babel system, it provides the source
%    code for the Galician language definition file.
%
%    The 'galician' style was originally adopted from the 'spanish'
%    style.
%
%    All the macrocodes have been translated from the spanish language
%    into the galician language, using the spanish-galician
%    dictionary:
%
%           X.L. Franco Grande
%           Diccionario Galego-Castelan e Vocabulario Castelan-Galego
%           Editorial Galaixa, Vigo 1968
%
%    The hyphenation patterns for the galician language should be the
%    same as the spanish language. I've inspected some galician essays
%    and nothing strange seems to point out that both languages might
%    use different hyphenation patterns. This still has to been
%    proved. I will check it anyway, and hope to report more as soon
%    as possible.
%
%    A small note to the months in the galician language:
%
%    'outono' will be used sometimes instead of 'outubro', but this
%    word will be used more to assign the season.
%
%    'nadal' will be used sometimes instead of 'decembro', but this
%    word will be used more for the event on Christmas.

%  \section{The Galician 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 definition macros for the
%    Galician language.
%
%    For this language the characters |'| |~| and |"| are made
%    active. In table~\ref{tab:galician-quote} an overview is given of
%    their purpose.
%    \begin{table}[htb]
%     \centering
%     \begin{tabular}{lp{8cm}}
%      \verb="|= & disable ligature at this position.\\
%      |"-| & an explicit hyphen sign, allowing hyphenation
%             in the rest of the word.\\
%      |\-| & like the old |\-|, but allowing hyphenation
%             in the rest of the word. \\
%      |'a| & an accent that allows hyphenation. Valid for all
%             vowels uppercase and lowercase.\\
%      |'n| & a n with a tilde. This is included to
%             improve compatibility with FTC. Works for uppercase too.\\
%      |"u| & a u with dieresis allowing hyphenation.\\
%      |"a| & feminine ordinal as in
%             1{\raise1ex\hbox{\underbar{\scriptsize a}}}.\\
%      |"o| & masculine ordinal as in
%             1{\raise1ex\hbox{\underbar{\scriptsize o}}}.\\
%      |~n| & a n with tilde. Works for uppercase too.
%     \end{tabular}
%     \caption{The extra definitions made by \texttt{galician.ldf}}
%     \label{tab:galician-quote}
%    \end{table}
%    These active accents character behave according to their original
%    definitions if not followed by one of the characters indicated in
%    that table.
%
% \StopEventually{}
%
%    The macro |\LdfInit| takes care of preventing that this file is
%    loaded more than once, checking the category code of the
%    \texttt{@} sign, etc.
% \changes{galician-1.2e}{1996/11/02}{Now use \cs{LdfInit} to perform
%    initial checks} 
%    \begin{macrocode}
%<*code>
\LdfInit{galician}\captionsgalician
%    \end{macrocode}
%
%    When this file is read as an option, i.e. by the |\usepackage|
%    command, \texttt{galician} could be an `unknown' language in which
%    case we have to make it known.  So we check for the existence of
%    |\l@galician| to see whether we have to do something here.
%
% \changes{galician-1.1c}{1994/06/26}{Now use \cs{@nopatterns} to
%    produce the warning}
%    \begin{macrocode}
\ifx\l@galician\@undefined
  \@nopatterns{Galician}
  \adddialect\l@galician0\fi
%    \end{macrocode}
%
%    The next step consists of defining commands to switch to (and
%    from) the Galician language.
%
% \begin{macro}{\captionsgalician}
%    The macro |\captionsgalician| defines all strings used
%    in the four standard documentclasses provided with \LaTeX.

% \begin{macro}{\noextrasgalician}
%
%    The macro |\extrasgalician| will perform all the extra
%    definitions needed for the Galician language. The macro
%    |\noextrasgalician| is used to cancel the actions of
%    |\extrasgalician|. 
%
%    For Galician, some characters are made active or are
%    redefined. In particular, the \texttt{"} character and the |~|
%    character receive new meanings this can also happen for the
%    \texttt{'} character when the option \Lopt{activeacute} is
%    specified.
%

%    \end{macrocode}
%
% \changes{galician-1.2a}{1995/03/14}{All the code for handling active
%    characters is now moved to \file{babel.def}}
%
%    Apart from the active characters some other macros get a new
%    definition. Therefore we store the current one to be able to
%    restore them later.
%
% \changes{galician-1.2f}{1997/01/08}{Added some comment signs to
%    prevent unwanted spaces in the output}
%    \begin{macrocode}

  \babel@save\'%
  \addto\extrasgalician{\def\'{\protect\@acute}}
  }{}
%    \end{macrocode}
% \end{macro}
% \end{macro}
%
%    All the code above is necessary because we need a few extra
%    active characters. These characters are then used as indicated in
%    table~\ref{tab:galician-quote}.
%
%    This option includes some support for working with extended,
%    8-bit fonts, if available. This assumes that the user has some
%    macros predefined. For instance, if the user has a |\@ac@a| macro
%    defined, the sequence |\'a| or |'a| will both expand to whatever
%    |\@ac@a| is defined to expand, presumably \texttt{\'a}.  The
%    names of these macros are the same as those in Ferguson's
%    ML-\TeX{} compatibility package on purpose. Using this method,
%    and provided that adequate hyphenation patterns exist, it is
%    possible to get better hyphenation for Galician than before. If
%    the user has a terminal able to produce these codes directly, it
%    is possible to do so.  If the need arises to send the document to
%    someone who does not have such support, it is possible to
%    mechanically translate the document so that the receiver can make
%    use of it.
%
%    To be able to define the function of the new accents, we first
%    define a couple of `support' macros.
%
%  \begin{macro}{\dieresis}
%  \begin{macro}{\textacute}
% \changes{galician-1.1c}{1994/06/26}{Renamed from \cs{acute} as that
%    is a \cs{mathaccent}}
%  \begin{macro}{\texttilde}
% \changes{galician-1.1c}{1994/06/26}{Renamed from \cs{tilde} as that
%    is a \cs{mathaccent}}
%
%    The original definition of |\"| is stored as |\dieresis|, because
%    the definition of |\"| might not be the default plain \TeX\
%    one. If the user uses \textsc{PostScript} fonts with the Adobe
%    font encoding the \texttt{"} character is not in the same
%    position as in Knuth's font encoding. In this case |\"| will not
%    be defined as |\accent"7F #1|, but as |\accent'310 #1|. Something
%    similar happens when using fonts that follow the Cork
%    encoding. For this reason we save the definition of |\"| and use
%    that in the definition of other macros. We do likewise for |\'|
%    and |\~|.
%    \begin{macrocode}
\let\dieresis\"
\let\texttilde\~
\@ifpackagewith{babel}{activeacute}{\let\textacute\'}{}
%    \end{macrocode}
%  \end{macro}
%  \end{macro}
%  \end{macro}
%
%  \begin{macro}{\@umlaut}
%  \begin{macro}{\@acute}
%  \begin{macro}{\@tilde}
%    If the user setup has extended fonts, the Ferguson macros are
%    required to be defined. We check for their existance and, if
%    defined, expand to whatever they are defined to. For instance,
%    |\'a| would check for the existance of a |\@ac@a| macro. It is
%    assumed to expand to the code of the accented letter.  If it is
%    not defined, we assume that no extended codes are available and
%    expand to the original definition but enabling hyphenation beyond
%    the accent. This is as best as we can do. It is better if you
%    have extended fonts or ML-\TeX{} because the hyphenation
%    algorithm can work on the whole word. The following macros are
%    directly derived from ML-\TeX{}.\footnote{A problem is perceived
%    here with these macros when used in a multilingual environment
%    where extended hyphenation patterns are available for some but
%    not all languages. Assume that no extended patterns exist at some
%    site for French and that \file{french.sty} would adopt this
%    scheme too. In that case, \texttt{'e} in French would
%    produce the combined accented letter, but hyphenation around it
%    would be suppressed. Both language options would need an
%    independent method to know whether they have extended patterns
%    available. The precise impact of this problem and the possible
%    solutions are under study.}

%    where long compound words are quite normal and all one needs is a
%    means to indicate an extra hyphenation position on top of the
%    ones that \TeX\ can generate from the hyphenation
%    patterns. However, the average length of words in Galician makes
