%  \section{The Breton language}
%
% \changes{breton-1.0e}{1996/10/10}{Replaced \cs{undefined} with
%    \cs{@undefined} and \cs{empty} with \cs{@empty} for consistency
%    with \LaTeX, moved the definition of \cs{atcatcode} right to the
%    beginning.}
%
%    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 Breton
%    language.
%
%    There are not really typographic rules for the Breton
%    language. It is a regional language (it's one of the celtic
%    languages) which is spoken in Brittany (West of France). So we
%    have a synthesis between Breton typographic rules and French
%    typographic rules. The characters \texttt{:}, \texttt{;},
%    \texttt{!} and \texttt{?} get a whitespace automatically before
%    them as in French.
%
%    This version (\fileversion, \filedate) supports new encoding
%    for ``the" character C'H, and uses new caption names.
%    Furthermore, compatibilities between pdfTeX, lualatex and xelatex	have been
%    upgraded with the deep help of Daniel Flipo.
%
%  \subsection{Basic interface}
%  \label{ssec-basic}
%
%    The \pkg{breton} language for Babel works for lualatex, xelatex and
%    pdflatex.
%
%    \textbf{Requirements:}
%    \begin{enumerate}
%      \item user’s documents \emph{must} be coded in UTF-8, also for
%        pdflatex.
%      \item pdflatex users \emph{must} use fonts in T1 encoding,
%        this means adding a\\ |\usepackage[T1]{fontenc}| command in the
%        preamble.
%    \end{enumerate}
%
%  \subsubsection{Punctuation}
%  \label{sssec-punctuation}
%
%    High punctuation (\texttt{:;!?}) in Breton requires, as in French,
%    some space to be added in front of it. The automatic insertion of
%    these spaces is handled in two different ways: for the pdftex and
%    xetex engines, active characters are used, while luatex provides
%    a safer alternative.
%
%    The default behaviour of \file{breton.ldf} is to add a thin
%    (nobreak, no stretch) space in front of \texttt{;!?} and an
%    inter-word (stretchable, nobreak) space in front of the colon.
%
%    These spaces are customisable through two commands
%    |\BRSetThinSpace| and |\BRSetColonSpace|. They both require three
%    mandatory arguments which are decimal numbers specifying
%    \textit{width}, \textit{stretch} and \textit{shrink} relative to
%    the relevant \textit{fontdimens}. Examples:\\
%    |\BRSetColonSpace{1}{1}{1}| provides exactly an inter-word space.\\
%    |\BRSetThinSpace{0.5}{0}{0}| provides a thin space (half width of
%    the inter-word space, no elasticity).
%
%    The automatic insertion of spaces in front of high punctuation is
%    disabled for Typewriter fonts and hence in verbatim mode.
%
%    A command |\NoBRspacing| is provided to disable the automatic
%    insertion of spaces in front of high punctuation if needed.
%    It is meant to be used inside a group.  For instance with
%    pdflatex or xelatex, coding |{\NoBRspacing (!)}| or
%    |{\NoBRspacing ??}| to avoid spurious spaces is
%    recommended. Fortunately lualatex handles these cases flawlessly.
%
%  \subsubsection{Caption names}
%  \label{sssec-captions-name}
%
%    The former  list of caption names  (such as |\chaptername|)
%    has been revisited, mainly according to recommendations of OPLB.
%    Furthermore,  |\partname|  is now numbered with ordinals
%    (e.g. \emph{Lodenn gentañ, Eil lodenn, ...}) instead of roman numbers
%    (e.g. \emph{Lodenn I, Lodenn II, ...}).
%
%    To the regular |\today| is added a new command |\deiziad{year}{month}{day}|
%    that prints the corresponding date in breton.

%
%    \begin{macrocode}
\ProvidesLanguage{breton}

%
%    The macro |\LdfInit| takes care of preventing that this file is
%    loaded more than once (even if both options \opt{breton} and
%    \opt{acadian} are used in the same document), checking the
%    category code of the \texttt{@} sign, etc.
%
%    \begin{macrocode}
\LdfInit{breton}{captionsbreton}
%    \end{macrocode}
%
%    Quit if Babel’s version is less than 24.14.
%    \begin{macrocode}

\else
   \let\bbl@tempa\endinput
   \PackageError{breton.ldf}
         {babel-breton requires babel v.24.14.\MessageBreak
          Aborting here}
         {Please upgrade Babel!}
\fi
\bbl@tempa
%    \end{macrocode}
%
%    Make sure that |\l@breton| is defined (fallback is language 0
%    US-english).
%    \begin{macrocode}
\ifdefined\l@breton
\else
  \@nopatterns{breton}
  \adddialect\l@breton0
\fi
%    \end{macrocode}
%
%    Breton uses the standard values of |\lefthyphenmin| (2)
%    and |\righthyphenmin| (3); let’s provide their values though,
%    as required by Babel.
%
%    \begin{macrocode}
\providehyphenmins{breton}{\tw@\thr@@}
%    \end{macrocode}
%
% \begin{macro}{\extrasbreton}
% \begin{macro}{\noextrasbreton}
%    The macro |\extrasbreton| will perform all the extra
%    definitions needed for the Breton language.
%    The macro |\noextrasbreton| is used to cancel the actions of
%    |\extrasbreton|.
%
%    In Breton, the quote character (U+27 or U+2019 or even 02BC) is
%    a  letter in expressions like |C'hwevrer| (February).
%    Breton hyphenation patterns need to provide entries for this kind
%    of words.  This means that its |\lccode| has to be non null in
%    Breton for proper hyphenation of those expressions, and has to be
%    reset to null when exiting Breton.
%
%    \begin{macrocode}
\def\extrasbreton{%
     \babel@savevariable{\lccode"27}%
     \lccode"27="27

       \lccode"2019="2019
     \fi
}
%    \end{macrocode}
%
%    One more thing |\extrasbreton| needs to do is to make sure that
%    ``Frenchspacing’’ is in effect.  |\noextrasfrench| will switch
%    ``Frenchspacing’’ off again if necessary.
%
%    A new conditional is used to switch off, if needed, automatic
%    insertion of spaces in front of \texttt{;} \texttt{!}  \texttt{?},
%    \texttt{:}, \texttt{«} and \texttt{»}.
%    \begin{macrocode}
\newif\ifBR@spacing
\addto\extrasbreton{\bbl@frenchspacing \BR@spacingtrue}
\addto\noextrasbreton{\bbl@nonfrenchspacing \BR@spacingfalse}
%    \end{macrocode}
% \end{macro}
% \end{macro}
%
%  \subsection{Breton apostrophe U+02BC}
%  \label{ssec-apost}
%
%    Strangely, some organisms, such as the Public Office for Breton
%    Language (OPLB, Office Public de la Lange Bretonne,  Ofis Publik
%    ar Brezhoneg), recommends to encode the character C'H with the
%    U+02BC apostrophe. As this character is missing from most fonts,
%    it's safer to replace it with a regular apostrophe.
%
%    Substitution of char U+02BC into U+0027 (pdftex) or U+2019
%    (unicode engines).
%
%    This is for the pdftex engine; caveat: the substitution holds for
%    all languages, not just Breton.
%    \begin{macrocode}
\ifcase\bbl@engine
  \DeclareUnicodeCharacter{02BC}{\char"0027}
%    \end{macrocode}
%    This is for the luatex engine.
%    \begin{macrocode}
\or
  \babelprehyphenation{breton}{ ʼ }{ string = ’ , remove }
%    \end{macrocode}
%    This is for the xetex engine.
%    \begin{macrocode}

%
%  \subsection{Punctuation}
%  \label{ssec-punct}
%
% \begin{macro}{\BRguillspace}
% \begin{macro}{\BRcolonspace}
% \begin{macro}{\BRthinspace}
%    Let’s define default values for punctuation spaces.
%    \begin{macrocode}
\newcommand*{\BRcolonspace}{\space}
\newcommand*{\BRthinspace}{\hskip .5\fontdimen2\font \relax}
\newcommand*{\BRguillspace}{\hskip .8\fontdimen2\font
                             plus .3\fontdimen3\font
                            minus .8\fontdimen4\font \relax}
%    \end{macrocode}
% \end{macro}
% \end{macro}
% \end{macro}
%
% \begin{macro}{\BRSetGuillSpace}
% \begin{macro}{\BRSetColonSpace}
% \begin{macro}{\BRSetThinSpace}
%    This command makes it easy to fine tune |\BRthinspace| and
%    |\BRcolonspace| in Breton.
%    It requires three mandatory arguments which are decimal numbers
%    specifying \textit{width}, \textit{stretch} and \textit{shrink}
%    relative to the relevant \textit{fontdimens}.\hlabel{BRsetspaces}
%    For instance |\BRSetColonSpace}{0.5}{0}{0}| defines
%    |\BRcolonspace| as a thinspace instead of a word space.
%    \begin{macrocode}
\newcommand*{\BRSetColonSpace}[3]{%

%
%  \subsubsection{Punctuation for the pdftex engine}
%  \label{sssec-punct-pdftex}
%
%    |\bbl@engine| is a Babel command which expands to 0, 1 or 2
%    according to the engine used for compilation, resp. pdftex,
%    luatex, xetex.
%    For pdftex the four high punctuation characters are made active.
%    \begin{macrocode}
\ifcase\bbl@engine
  \initiate@active@char{:}
  \initiate@active@char{;}
  \initiate@active@char{!}
  \initiate@active@char{?}
%    \end{macrocode}
%    We tune the amount of space before \texttt{;}
%    \texttt{!}  \texttt{?} and \texttt{:}.
%    In horizontal mode, if a space has been typed before `;’ we
%    remove it. Then a non-breaking |\BRthinspace| is inserted.
%    \begin{macrocode}
  \declare@shorthand{breton}{;}{%
    \ifBR@spacing
      \ifhmode
        \ifdim\lastskip>1sp \unskip \fi
        \penalty\@M \BRthinspace
      \fi
    \fi
%    \end{macrocode}
%    Now we can insert a |;| character.
%    \begin{macrocode}
    \string;}
%    \end{macrocode}
%    The next three definitions are very similar.
%    \begin{macrocode}
  \declare@shorthand{breton}{!}{%
    \ifBR@spacing
      \ifhmode
        \ifdim\lastskip>1sp \unskip \fi
        \penalty\@M \BRthinspace
      \fi
    \fi
    \string!}
  \declare@shorthand{breton}{?}{%
    \ifBR@spacing
      \ifhmode
        \ifdim\lastskip>1sp \unskip \fi
        \penalty\@M \BRthinspace
      \fi
    \fi
    \string?}
  \declare@shorthand{breton}{:}{%
    \ifBR@spacing
      \ifhmode
        \ifdim\lastskip>1sp \unskip \fi
        \penalty\@M \BRcolonspace
      \fi
    \fi
    \string:}
%    \end{macrocode}
%    When the active characters appear in an environment where their
%    Breton behaviour is not wanted they should give an `expected’
%    result.  Therefore we define shorthands at system level as well.
%    \begin{macrocode}
  \declare@shorthand{system}{:}{\string:}
  \declare@shorthand{system}{!}{\string!}
  \declare@shorthand{system}{?}{\string?}
  \declare@shorthand{system}{;}{\string;}
%    \end{macrocode}
%    We specify that the Breton group of shorthands should be used when
%    switching to Breton.
%    \begin{macrocode}
  \addto\extrasbreton{\languageshorthands{breton}%
%    \end{macrocode}
%    These characters are `turned on’ once, later their definition may
%    vary.  Don’t misunderstand the following code: they keep being
%    active all along the document, even when leaving Breton.
%    \begin{macrocode}
    \bbl@activate{:}\bbl@activate{;}%
    \bbl@activate{!}\bbl@activate{?}%
  }
  \addto\noextrasbreton{%
    \bbl@deactivate{:}\bbl@deactivate{;}%
    \bbl@deactivate{!}\bbl@deactivate{?}%
  }
%    \end{macrocode}
%    French quotes (« and ») also require some additional space;
%    \begin{macrocode}
  \DeclareUnicodeCharacter{00AB}{\BR@og}
  \DeclareUnicodeCharacter{00BB}{\BR@fg}
  \newcommand*{\BR@og}{%
    \ifBR@spacing \guillemotleft\penalty\@M\BRguillspace\ignorespaces
    \else \guillemotleft
    \fi}
  \newcommand*{\BR@fg}{%
    \ifBR@spacing \ifdim\lastskip>\z@\unskip\fi \penalty\@M\BRguillspace
       \guillemotright
    \else \guillemotright
    \fi}
%    \end{macrocode}
%
%\subsubsection{Punctuation for the luatex engine}
%  \label{sssec-punct-luatex}
%
%    For the LuaTeX engine, we use the ``transforms’’ from Babel’s
%    kernel and we exclude monospaced fonts from their application.

%  \subsubsection{Punctuation for the xetex engine}
%  \label{sssec-punct-xetex}
%
%    For the xetex engine, inter-character rules are defined to insert
%    spaces before the `high punctuation’ characters.
%    \begin{macrocode}
\or
  \babelcharclass{breton}{thin}{;!?}
  \babelcharclass{breton}{colon}{:}
  \babelinterchar{breton}{default,boundary}{thin}{%
    \ifBR@spacing
       \ifhmode
          \ifdim\lastskip>1sp \unskip \fi
          \penalty\@M\BRthinspace
        \fi
     \fi}%
  \babelinterchar{breton}{default,boundary}{colon}{%
    \ifBR@spacing
       \ifhmode
          \ifdim\lastskip>1sp \unskip \fi
          \penalty\@M\BRcolonspace
        \fi
     \fi}%

%    \end{macrocode}
%    This is for French quote characters:
%    \begin{macrocode}
  \babelcharclass{breton}{og}{«}
  \babelcharclass{breton}{fg}{»}
  \babelinterchar{breton}{og}{default,boundary}{%
    \ifBR@spacing \penalty\@M\BRguillspace \ignorespaces\fi}
  \babelinterchar{breton}{default,boundary}{fg}{%

\fi
%    \end{macrocode}
%
%  \subsubsection{Punctuation switches common to all engines}
%  \label{sssec-punct-switches}
%
%    Automatic insertion of spaces in front of high punctuation is
%    canceled in for Typewriter fonts and hence in verbatim.
%    For luatex, nothing has to be done as Typewriter fonts are excluded
%    from Babel transforms.
%    For pdftex and xetex, this is done by switching the |\ifBR@spacing|
%    flag. As |\ttfamily| action may be global (when not issued inside
%    a group), |\rmfamily| and |\sffamily| need to be patched too.
%    \begin{macrocode}
\ifnum\bbl@engine=\@ne
\else
  \AddToHook{cmd/ttfamily/after}{\BR@spacingfalse}
  \AddToHook{cmd/rmfamily/after}{\BR@spacingtrue}
  \AddToHook{cmd/sffamily/after}{\BR@spacingtrue}
\fi
%    \end{macrocode}
%
% \begin{macro}{\BRNoAutoSpacing}
%    The following command disables automatic spacing for high
%    punctuation.
%    It is engine independent and is meant to be used inside a group.
%    The faked definition of |\texorpdfstring| will be overwritten
%    by \file{hyperref.sty}.
%
