%    This file is part of the babel system, it provides the source code for
%    the Galician language-specific 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-specific 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 {\tt galician.sty}}
%     \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{}
%
%    As this file needs to be read only once, we check whether it was
%    read before. If it was, the command |\captionsgalician| 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\captionsgalician
\else
  \selectlanguage{galician}
  \expandafter\endinput
\fi
%    \end{macrocode}
%
%    Tell the \LaTeX\ system who we are and write an entry on the
%    transcript.
%    \begin{macrocode}
\ProvidesFile{galician.sty}[1994/06/26 v1.1c
         Galician support from the babel system]
%    \end{macrocode}
%
% \begin{macro}{\atcatcode}
%    This file, \file{galician.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 galician} 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}
%
%    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 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\undefined\l@galician
  \@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{macrocode}
\addto\captionsgalician{%
  \def\prefacename{Preface}%   <- This needs translation!!

  \def\alsoname{See also}%     <- This needs translation!!
}
%    \end{macrocode}
% \end{macro}
%
% \begin{macro}{\dategalician}
%    The macro |\dategalician| redefines the command |\today| to
%    produce Galician dates.
%    \begin{macrocode}
\def\dategalician{%
  \def\today{\number\day~de\space\ifcase\month\or
    xaneiro\or febreiro\or marzal\or abril\or maio\or xu\~no\or
    xullo\or agosto\or setembro\or outubro\or novembro\or decembro\fi
    \space de~\number\year}}
%    \end{macrocode}
% \end{macro}
%
% \begin{macro}{\extrasgalician}
% \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|.
%
%    \begin{macrocode}
\addto\extrasgalician{%
  \babel@add@special\"%
  \babel@add@special\'%
  \babel@add@special\~}
%    \end{macrocode}
%
%    When |\noextrasgalician| is executed they are no longer
%    `special'.
%
%    \begin{macrocode}
\addto\noextrasgalician{%
  \babel@remove@special\"%
  \babel@remove@special\'%
  \babel@remove@special\~}
%    \end{macrocode}
%
%    Before the category codes of these characters can be changed
%    their current category codes need to be stored in order to
%    restore them later.
%
% \changes{galician-1.0.2}{13 september 93}{The definition of the
%    active tilde was not being restored on exit.}
%    \begin{macrocode}
\addto\extrasgalician{%
  \babel@savevariable{\catcode`\"}\babel@save\active@dq
  \babel@savevariable{\catcode`\'}\babel@save\active@ac
  \babel@savevariable{\catcode`\~}\babel@save\active@til
  \babel@save~}
%    \end{macrocode}
%
%    Now that the category codes are stored we can assign new category
%    codes to these three characters.
%    \begin{macrocode}
\addto\extrasgalician{\catcode`\"\active\catcode`\'\active%
                     \catcode`\~\active}
%    \end{macrocode}
%    And we can define them\footnote{The way that the active{\tt "} is
%    handled should be like it is for German and Dutch.}.
%
% \changes{galician-1.0.2}{23 september 93}{The accents had to be made
%    active during their own definition}
%    \begin{macrocode}
\begingroup \catcode`\"\active \catcode`\~\active \catcode`\'\active
\def\x{\endgroup
  \addto\extrasgalician{%
    \def'{\protect\active@ac}\let\active@ac\galician@active@ac
    \def~{\protect\active@til}\let\active@til\galician@active@til
    \def"{\protect\active@dq}\let\active@dq\galician@active@dq}}
\x
%    \end{macrocode}
%
%    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.
%
%    \begin{macrocode}
\addto\extrasgalician{\babel@save\"\babel@save\'%
                      \babel@save\~\babel@save\a}
%    \end{macrocode}
%
%    Now that their current meanings are saved, we can safely redefine
%    them.
%
%    \begin{macrocode}
\addto\extrasgalician{\let\a\galician@a}
%    \end{macrocode}
%
%    When the command |\"| appears in a moving argument (such as, for
%    example, {\tt\ttbs section\{El Cig\ttbs"\{u\}ela\}}) an error
%    message might occur. The reason is that when the argument is
%    written to the {\tt .aux} file macros are expanded. The original
%    definition of |\"| is:
%\begin{verbatim}
%    \def\"#1{{\accent"7F #1}}
%\end{verbatim}
%    When the \file{.aux} file is processed and the \file{.toc} file
%    is written while the {\tt "} character is active, the expansion
%    of {\tt "} will replace it, resulting in a piece of code like:
%\begin{verbatim}
%    ... re\accent \protect\active@dq ele ...
%\end{verbatim}
%    When \TeX\ reads this it will protest about a missing number.
%
%    To circumvent this, |\"| is redefined, using one of the support
%    macros for the definition of the active {\tt "}. The same goes
%    for the other accents.
%    \begin{macrocode}
\addto\extrasgalician{\def\"{\protect\@umlaut}%
                      \def\'{\protect\@acute}%
                      \def\~{\protect\@tilde}}
%    \end{macrocode}
% \end{macro}
% \end{macro}
%
%
%  \begin{macro}{\galician@a}
%   The active {\tt '} interferes with the alternate accent macro
% |\a| used mostly inside a |\tabbing| environment.
%   This is a redefinition of |\a| that solves the problem.
%    \begin{macrocode}
\def\galician@a#1{{\if\string#1'\aftergroup\@acute
            \else \expandafter\aftergroup\csname a#1\endcsname\fi}}
%    \end{macrocode}
%  \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 {\tt
%    \'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}{\dq}
%  \begin{macro}{\til}
%    We save the original double quote character in |\dq| to keep it
%    available. We keep in |\til| the original tilde character.  We
%    rely on |\rq| to contain the right quote.
% \changes{galician-1.0.2}{23 september 93}{The active tilde was not
%    expanding to a correct unbreakable space when not followed by n.}
%    \begin{macrocode}
\begingroup \catcode`\"12
\edef\x{\endgroup
  \def\noexpand\dq{"}
  \def\noexpand\til{~}}
\x
%    \end{macrocode}
%  \end{macro}
%  \end{macro}
%
%  \begin{macro}{\dieresis}
%  \begin{macro}{\textacute}
% \changes{v1.1c}{1994/06/26}{Renamed from \cs{acute} as that
%    is a \cs{mathaccent}}
%  \begin{macro}{\texttilde}
% \changes{v1.1c}{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 {\sc PostScript} fonts with the Adobe font
%    encoding the {\tt "} 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\textacute\'
\let\texttilde\~
%    \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 {\tt french.sty} would adopt this scheme
%    too. In that case, \mbox{\tt '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.}

%  \begin{macro}{\galician@active@ac}
%     We do likewise for the acute accent. There is a problem in this
%    case. The |\mathcode| of {\tt '} is |"8000| that makes it sort of
%    active, but not quite. The following method, using part of the
%    definition in plain\TeX{} seems to work. First we check if we are
%    in math mode {\em before\/} consuming the parameter.
%
%    \begin{macrocode}
\def\galician@active@ac{{%
    \ifmmode\aftergroup\galician@math@ac
    \else\aftergroup\first@galician@active@ac\fi}}
%    \end{macrocode}
%
%  \begin{macro}{\galician@math@ac}
%     A |\mathcode| of |"8000| means that the character should be
%    treated inside math mode as if it were active.  This trick is
%    used in plain\TeX{} to make things like $a'''$ work. The
%    following code can be found in plain\TeX:
%  \begin{verbatim}
%       \gdef'{^\bgroup\prim@s}
%  \end{verbatim}
%     However, the coding of |\prim@s| is done under the assumption
%    that {\tt '} is not active. The following macro is a rewrite of
%    the code above, that makes the assumption true. The expansion of
%    |\prim@s| will provide the apparently missing |\egroup| that will
%    revert the effect of the |\catcode| change.

%    \begin{macro}{\dotlessi}
%    To properly support all the configurations required, we need to
%    have some macro that gives us the position that the dotless `i'
%    occupies in our fonts, that is, the equivalent of |\i| that
%    cannot be used inside a |\csname| as would be desirable.
%
%    The following solution was suggested by Raymond Chen. After this
%    code sequence, |\dotlessi| can be used to construct a control
%    sequence name.
%
%    \begin{macrocode}
    \def\thechar#1{{\uccode`!=#1\relax\uppercase{\gdef\next{!}}}}

%    All that is left now is the redefinition of |\-|. The new version
%    of |\-| should indicate an extra hyphenation position, while
%    allowing other hyphenation positions to be generated
%    automatically. The standard behaviour of \TeX\ in this respect is
%    unfortunate for Galician but not as much as for Dutch or German,
%    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
%    this desirable and so it is kept here.

%
%    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
%    Galician.
%
%    \begin{macrocode}
\selectlanguage{galician}
%    \end{macrocode}
%
%    Finally, the category code of {\tt @} is reset to its original
%    value. The macrospace used by |\atcatcode| is freed.
