% \section{The Piedmontese 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
%    Piedmontese language\footnote{Language ISO 639 coded with letter identification \texttt{pms}. This file was created by Claudio Beccari; see the source file for more information.}.
%
% \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. |\CurrentOption| is actually the name of 
%    language that was specified as an option in the call to \babel.
% \iffalse
%&lt;*code&gt;
% \fi
%    \begin{macrocode}
\LdfInit{\CurrentOption}{captions\CurrentOption}
%    \end{macrocode}
%
%    When this file is read as an option to the |\usepackage|
%    command that loads |babel|, \texttt{piedmontese} could be an
%    `unknown' language, or better, a language who's patterns have
%    not been loaded into the format file; in this case we have to
%    make it known. So we check for the existence of |\l@piedmontese|
%    to see whether we have to do something here. If the Piedmontese
%    patterns have not (yet) been loaded in the format file, we prefer
%    to declare |piedmontese| a dialect of |italian| rather than
%    a dialect of |english|, although we resort to the latter language
%    if also the Italian patterns have not been loaded into the format
%    file: this unfortunately happens when a basic \TeX\ system
%    installation is being used.
%
%    \begin{macrocode}

% \begin{macro}{\captionspiedmontese}

%
% \begin{macro}{\datepiedmontese}
%    The macro |\datepiedmontese| redefines the command |\today| to
%    produce Piedmontese dates. The proposition corresponding to
%    `of' has three spellings in Piedmontese, one general (\"ed),  one to
%    be used in front of words starting with a group of consonants (d\"e),
%    and a third one, that derives from the latter by vocalic elision (d')
%    to be used in front of words starting with a vowel.
%    \begin{macrocode}
\@namedef{date\CurrentOption}{%
    \def\today{\number\day\space \space\ifcase\month\or
      \"ed gen\'e\or \"ed fevr\'e\or \"ed mars\or d'avril\or 
      \"ed maj\or \"ed giugn\or \"ed luj\or d'agost\or 
      d\"e st\`ember\or d'ot\'ober\or \"ed nov\`ember\or 
      d\"e dz\`ember\fi\space dal\space\number\year}}
%    \end{macrocode}
% \end{macro}
%
%  \begin{macro}{\piedmontesehyphenmins}
%    This macro is used to store the correct values of the hyphenation
%    parameters |\lefthyphenmin| and |\righthyphenmin|.
%    \begin{macrocode}
\providehyphenmins{\CurrentOption}{\tw@\tw@}
%    \end{macrocode}
%  \end{macro}
%
% \begin{macro}{\extraspiedmontese}
% \begin{macro}{\noextraspiedmontese}
%    The next step consists of defining commands to switch to (and
%    from) the Piedmontese language.
%
%    The macro |\extraspiedmontese| will perform all the extra
%    definitions needed for the Piedmontese language. The macro
%    |\noextraspiedmontese| is used to cancel the actions of
%    |\extraspiedmontese|. In particular we set pretty high
%    default values for widow and club lines and very high
%    demerits to avoid that the last line starts with the
%    second half of a hyphenated word. We also assign a non zero
%    value |\lccode| to the apostrophe that in Piedmontese is being
%    used for marking a vocalic elision and for apocope; by giving it a non 
%    zero value, the hyphenation algorithm treats the phrase formed
%    by the article or articulated preposition and the following
%    term as a single word and the patterns for Piedmontese take care
%    of avoiding line breaks right after the apostrophe.
%
%    \begin{macrocode}
\expandafter\addto\csname extras\CurrentOption\endcsname{%
  \babel@savevariable\clubpenalty
  \babel@savevariable\widowpenalty
  \babel@savevariable\@clubpenalty
  \clubpenalty3000\widowpenalty3000\@clubpenalty\clubpenalty}%
\expandafter\addto\csname extras\CurrentOption\endcsname{%
  \babel@savevariable\finalhyphendemerits
  \finalhyphendemerits50000000}%
\expandafter\addto\csname extras\CurrentOption\endcsname{%
  \lccode`'=`'}%
\expandafter\addto\csname noextras\CurrentOption\endcsname{%
  \lccode`'=0}%
%    \end{macrocode}
% \end{macro}
% \end{macro}
%
% The double straight quote |"| is made active for the current language.
% Its purpose is primarily to produce a diacritic hyphen; meanwhile 
% it is convenient to let it perform some other little tasks, such as
% to insert an etymologic line break, to simplify the |\slash| command, 
% and to ease the introduction of the double raised open quotes, that are
% cumbersome to insert with the Italian keyboard.
%
% The main activation of the |"| sign is done through the babel command
% |\declare@shorthand| that checks if the |"| has been used in math or
% in text mode; if in text mode, a service macro |\pms@next| is defined
% that upon execution lets a future token be aliased by the implicit token
% c.s. |\pms@temp|, while the actual work is demanded to |\pms@cwm|.
%    \begin{macrocode}
\initiate@active@char{"}%
\expandafter\addto\csname extras\CurrentOption\endcsname{%

    \def\pms@next{\futurelet\pms@temp\pms@cwm}%

}%
%    \end{macrocode}
%
% After defining another service macro |\pms@@cwm| for introducing a
% discretionary break that may be inserted in the middle of a word,
% allowing another break point, but allowing hyphenation in both letter
% strings that sit at either side of this break point. The the |\pms@cwm|
% macro is defined to perform the necessary actions depending on the
% nature of the token memorized into the temporary c.s. |\pms@temp|.
% The |\@gobble| macro must be repeated at each test, otherwise it
% gobbles the |\fi| of the outer test. An |\expandafter| construct might
% reduce this repetition.
%    \begin{macrocode}
\DeclareRobustCommand*{\pms@cwm}{\let\pms@@next\relax
\ifcat\noexpand\pms@temp a%
    \def\pms@@next{\pms@@cwm}%

    \else
        \ifx\pms@temp-%
           \def\pms@@next{\bbl@allowhyphens-\bbl@allowhyphens\@gobble}%
        \else
            \ifx\pms@temp"%
                \def\pms@@next{``\expandafter\@gobble\string}%
            \fi
        \fi
    \fi
\fi
\pms@@next}%
%    \end{macrocode}
% \begin{macro}{\noextraspiedmontese}
% This done, we are ready to prepare the switch back to another language"
%    \begin{macrocode}
\expandafter\addto\csname noextras\CurrentOption\endcsname{%
\bbl@deactivate{"}}
%    \end{macrocode}
% \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.
%    \begin{macrocode}
