% This package extends the typesetting facilities of the \textsl{latin} option
% to the \pack{babel} package for typesetting Latin according to the
% tradition of ecclesiastic documents; these documents are mainly the
% devotional books used by the Roman Catholic clergy, but not limited to them,
% that are being published not only by the Vatican Typography, but also by many
% Printing Companies around the world. This package works only with pdf\/\LaTeX;
% if an attempt is made to use it while typesetting with Xe\string|Lua\,\LaTeX, its
% input is aborted and nothing is done. Most additions and modifications that
% can be achieved with this package under pdf\/\LaTeX\ typesetting, are obtained
% thanks to clever use of the OpenType fonts when using Xe\string|Lua \,\LaTeX.
%
% \end{abstract}
%
% \section{Introduction}
% This small extension package extends the features of \texttt{latin.ldf} 
% by adding a certain level of "frenchization" to the way of typesetting
% Ecclesiastical Latin; in particular all punctuation marks, except comma
% and full stop are preceded by a small space. The guillemots are also
% accompanied by small spaces to the right of the opening marks and to the 
% left of the closing ones, with the provision of removing spurious previous 
% spaces. Footnotes are not indented and their reference number is not an
% exponent, although footnote marks in the text keep being exponents.
%
% The acute accent (actually the apostrophe sign) is made active 
% so as to set an acute accent over the following vowel (notice that in Latin
% there is no elision, so there cannot be any conflict between the acute accent
% and the elision apostrophe). Ecclesiastical Latin uses the
% \ae\ and \oe\ ligatures. Goodman asked to declare `a' and `o' as active
% characters so that the spelling |ae| and |oe| would automatically produce the
% equivalent of |\ae| and |\oe| respectively.
%
% In practice Beccari found serious programming problems with this solution and
% adopted an alternative one; specifically the adopted solution was to type in
% |"ae| and |"oe| respectively, and \ae\ and \oe\ would be inserted in the
% source text without the need of leaving blanks after the control sequences or
% the need of inserting extra braces; therefore one types in |c"aelum| and this
% is equivalent to \verb*|c\ae lum| or |c{\ae}lum| or |c\ae{}lum|; the saving in
% the% input stream is evident and typos are likely less frequent.
%
% The active apostrophe for the acute accent behaves properly also with y
% and |'ae| and |'oe| produce the accented diphthongs.
%
% Of course, when using the OT1 encoding all accents interfere with
% hyphenation and kerning. When using the T1 encoding this interference
% takes place only with the accented diphthongs \ae\ and \oe; no visible
% problems for the lack of kerning, but no hyphenation takes place after
% the accented diphthongs until the end of the word, even if the grammar
% allowed it; you can correct by hand this behavior if you add an \textsc{ascii}
% straight double quote \emph{after} the accented diphthong: $(a)$ if
% the grammar allows a line break at that point, and $(b)$ if justification
% of the right margin requires it.
% 
%\section{Usage}
% Previous versions of this package were loaded after package \babel with
% the |latin| language option; you can still do this way because for backwards
% compatibility this procedure is maintained, but we discourage it for the
% reasons that are explained hereafter.

% With this new version the preferred procedure is to specify the
% |ecclesiastic| modifier to the |latin| language option. This very file
% contains le line:
%\begin{verbatim}
%\usepackage[latin.ecclesiastic,english]{babel}
%\end{verbatim}
% Of course this new way of loading the package assures it to be loaded
% at the proper moment, but it requires a \babel of at least version 3.9k;
% the old procedure is still usable with previous versions of the \babel
% package.
%
% \textbf{Important notice}: This package works only while using the |pdfLaTeX|
% typesetting program and \babel; if you try to use it with |XeLaTeX| or
% |LuaLaTeX| its loading procedure issues an error message and the it aborts.
% if for any reason you have to use |XeLaTeX| or |LuaLaTeX| you can safely
% run them without loading thins package, but simply specifying the
% ``key=value'' option |variant=ecclesiastic| in a similar way as you specify
% the |ecclesiastic| modifier when using \babel.  With |XeLaTeX| you have
% the full functionality of the ecclesiastic Latin variant, while, at the
% moment, with |LuaLaTeX| the functionality misses the particular spacing
% around some punctuation marks and around guillemots. This functionality
% is under study, but it is hopefully available with the next package version.
%
% After in one way or another you have assured the presence of the special macros that implement the ecclesiastic Latin style,
% all you have to do (with \babel) is to input your source code the usual way,
% except that for guillemots and accents you are supposed to use the |"| and
% the |'| active characters. The input code
%\begin{verbatim}
%Ita enim fit, ut regn'are is "< in m'entibus h'ominum "> dic'atur non 
%tam ob mentis 'aciem scienti'aeque su"ae amplit'udinem, quam quod ipse est 
%V'eritas, et verit'atem ab eo mort'ales haur'ire atque obedi'enter acc'ipere 
%nec'esse est;  "< in volunt'atibus "> item "< h'ominum ">, quia \dots
%\end{verbatim}
% will produce the following text:
%\begin{quote}\otherlanguage{latin}
%Ita enim fit, ut regn'are is "< in m'entibus h'ominum "> dic'atur non 
%tam ob mentis 'aciem scienti'aeque su"ae amplit'udinem, quam quod ipse est 
%V'eritas, et verit'atem ab eo mort'ales haur'ire atque obedi'enter acc'ipere 
%nec'esse est;  "< in volunt'atibus "> item "< h'ominum ">, quia \dots
%\end{quote}
% Notice that the source text has spaces around the guillemots, but the
% typeset code has the right small and constant space, irrespective of
% justification. Notice the use of the `acute' accent (actually the
% apostrophe) for accented vowels and diphthongs. Notice the space in the
% typeset text before the semicolon; this space is gobbled and substituted
% with the proper space.
%
% \section{Documented code}
% Some checks in order to use this package together with the one it
% should extend. Firse we load the |iftex| package in order to have the right switch to test if we are typesetting with the |pdftex| engine; inf not, an error message is issued and loading aborted.

% The following code was borrowed from \pack{frenchle.sty} by Bernard Gaule,
% but there are several modifications; in particular we avoid the horrible
% patch made up with the shorter and  wider script size math signs.
% The Latin Modern fonts are preferred if they are available. When the T1
% encoding is in force the guillemots are taken from the current font; if
% you want to typeset ecclesiastic Latin, you'd better use the T1 font
% encoding; if you don't, you may get proper accented glyphs, but no hyphenation
% after any accented glyph until the end of the word. No attempt is made to
% create fake guillemots or to pick them from fonts that do not match the
% current text font. In any case we provide the command |\FrenchGuillemetsFrom|
% ( and its alias |\FrenchGuillemotsFrom|) that allows the user to chose what
% font s/he likes best.
%
% The first macro specifies a common interface for choosing where to get
% guillemots from.
%    \begin{macrocode}
\let\og\empty\let\fg\empty%

   \def\FrenchGuillemetsFrom#1#2#3#4{%
     \DeclareFontEncoding{#1}{}{}%
     \DeclareFontSubstitution{#1}{#2}{m}{n}%
     \DeclareTextCommand{\guillemotleft}{T1}{%
        {\fontencoding{#1}\fontfamily{#2}\selectfont\char#3}}%
     \DeclareTextCommand{\guillemotright}{T1}{%
        {\fontencoding{#1}\fontfamily{#2}\selectfont\char#4}}}

   \let\FrenchGuillemotsFrom\FrenchGuillemetsFrom

%    \end{macrocode}
% Then come the macros for selecting various type of guillemots: the  
%|\ToneGuillemets| macro selects them from the T1 encoded fonts; 
% according to the user input encoding, in particular the |utf8| one, when
% this package is loaded the macros |\guillemotleft| and |\guillemotright|
% should be defined; if either one is not, then the default guillemots are
% taken from the T1 encoded Latin Modern fonts:
%    \begin{macrocode}
\AtBeginDocument{%
\unless\ifcsname guillemotleft\endcsname
   \def\ToneGuillemets{\FrenchGuillemetsFrom{T1}{lmr}{19}{20}}\fi}
%    \end{macrocode}
% Having defined the symbols, we now provide to the spacing; we chose a smaller
% space than in French typography, but, essentially this glue is without
% stretch and shrink components, so that this space remains constant and
% does not stretch or shrink for helping in line justification.
%    \begin{macrocode}
   \def\guill@spacing{\penalty\@M\hskip.3\fontdimen2\font
                       \@plus\z@\@minus\z@}
%    \end{macrocode}
% Notice that |\fontdimen2\font| gets the normal inter word space of the
% current font; therefore the defined spacing of the guillemots is about
% 1\,pt, with a 10\,pt sized font.
%
% Now we are in the position to define the opening and the closing
% guillemot commands.
%
% The spacings on the interior of the guillemots and the spacings before the 
% ``high'' punctuation marks are smaller than with the \texttt{frenchle.sty}
% settings for the French typography. This has been made according to Robert
% Bringhurst's recommendation to maintain tight spacing, in particular before
% the punctuation marks and within the French quotes. 
%
% Since Beccari is not used to such spacings, forbidden in Italian typography,
% he finds the traditional French spacings very large, too large for his taste. 
% Bringhurst recommendations come in very handy to justify the chosen spacings.
% May be who is used to wider spacings finds them too tight. We think we found
% a compromise.
%    \begin{macrocode}
   \DeclareRobustCommand*{\begin@guill}{\leavevmode
                             \guillemotleft\penalty\@M\guill@spacing
                             \ignorespaces}
   \DeclareRobustCommand*{\end@guill}{\ifdim\lastskip>\z@\unskip\fi
                     \penalty\@M\guill@spacing\guillemotright{}}
%    \end{macrocode}
%
% We add the definition of |\og| (\emph{ouvrir guillemets}) and |\fg|
% (\emph{fermer guillemets}) to the |\extraslatin| list, as well as we
% add their `emptiness' to the |\noextraslatin| one.
%    \begin{macrocode}
   \addto\extraslatin{%
         \renewcommand{\og}{\begin@guill}\renewcommand{\fg}{\end@guill}%
   }   
   \addto\noextraslatin{\let\og\empty\let\fg\empty}
%    \end{macrocode}
%
% Therefore open guillemots may be input with the |\og| macro and the
% closed ones with the |\fg| macro. This might be inconvenient, so that
% the |"<| and |">| shortcuts should be preferred; these shortcuts assure
% that the spaces after these shortcuts are really spaces and are not
% used to terminate the macro name. B.~Gaulle uses the |\xspace| macro from
% the xspace package, but if this package is not loaded or is not available, the 
% |\xspace| macro behaves as |\relax| and does not produce what is intended to
% do. See below the extended definition of the |"| shortcut active character.
%
% Here we make the apostrophe an active char and define the shortcuts for
% Latin that introduce the acute accent over the specified vowels, lower
% and upper case. Probably upper case is useless, but it does not harm.
%    \begin{macrocode}
\initiate@active@char{'}%
\addto\extraslatin{\bbl@activate{'}}%
\addto\noextraslatin{\bbl@deactivate{'}}%

\declare@shorthand{latin}{'a}{\@ifnextchar e{\'\ae\@gobble}{\'a}}

\declare@shorthand{latin}{'U}{\'U}
\declare@shorthand{latin}{'Y}{\'Y}
%    \end{macrocode}
%
% Here we redefine the |"| shortcut active character;
% it is borrowed from \pack{italian.ldf}, but a new |\LT@cwm| macro is
% added to the existing |\lt@@cwm| one so as to cope also with |"ae| and |"oe|,
% besides the guillemot commands.
%
% The following declaration is probably a repetition of what is already in 
% \pack{latin.ldf}
%    \begin{macrocode}
\declare@shorthand{latin}{"}{%
\textormath{\def\lt@next{\futurelet\lt@temp\lt@cwm}}%
           {\def\lt@next{''}}\lt@next
}%
%    \end{macrocode}
%
% This also should already be in \pack{latin.ldf}; it is the command that
% inserts a discretionary break, but does not inhibit hyphenation in the
% rest of the word.
%    \begin{macrocode}
\def\lt@@cwm{\nobreak\discretionary{-}{}{}\nobreak\hskip\z@skip}%
%    \end{macrocode}
%
% This, for what concerns Latin, is new as an interface with the definitions
% of the guillemots
%    \begin{macrocode}
\def\lt@@ocap#1{\begin@guill}\def\lt@@ccap#1{\end@guill}%
%    \end{macrocode}
%
% This is completely new; it deals with |\ae| and |\oe|; since |\ae| is much
% more frequent than |\oe|, we start with testing for an `a' followed by
% an `e', otherwise we test about the presence of an `o':
%    \begin{macrocode}
\DeclareRobustCommand\LT@cwm[2]{%
    \ifx#1a\bbl@afterelse
       \maybeae#1#2%    
    \else\bbl@afterfi
        \testoe#1#2%
    \fi}
%    \end{macrocode}
%
% If a sequence |ae| was detected, then |\ae| is inserted in the input stream
% in place of that sequence, otherwise the two tokens are inserted in the input
% stream preceded by the discretionary break implied by the presence of the
% |"| sign that triggered the whole process.
%
%    \begin{macrocode}
\def\maybeae#1#2{%
    \ifx#2e\bbl@afterelse
       \ae%
    \else\bbl@afterfi
        \lt@@cwm#1#2%
    \fi
}
%    \end{macrocode}
%
% The same procedure is valid for the sequence |oe|
%    \begin{macrocode}
\def\maybeoe#1#2{%
    \ifx#2e\bbl@afterelse
       \oe%
    \else\bbl@afterfi
       \lt@@cwm#1#2%
    \fi
}
%    \end{macrocode}
%
% But the presence of an `o' must be checked before activating the previous
% macro:
%    \begin{macrocode}
\def\testoe#1#2{%
   \ifx#1o\bbl@afterelse
       \maybeoe#1#2%
   \else\bbl@afterfi
       \lt@@cwm#1#2%
   \fi}
%    \end{macrocode}
%
% This is the real execution of the |"| shortcut; remember that |\lt@cwm|
% is activated by |\lt@next|, the action associated with |"| when outside
% the math mode; furthermore |\lt@temp| contains the token following
% the |"| sign. Notice that the category code of the |\lt@temp| is compared
% to that of a generic letter; the choice of `e' is absolutely irrelevant,
% because it is a generic letter; any other letter would do the same.
% So, first the temporary token category code is compared to that of a letter;
% if it's a letter then
% |\LT@cwm| is executed; the latter on turn looks for an `a' or an `o' and
% possibly inserts a diphthong or a discretionary break; otherwise the
% temporary token is compared to \verb+|+, so that the shortcut \verb+"|+
% is possibly executed by inserting a discretionary break and by gobbling
% the bar; otherwise it checks for a `less than' sign and
% possibly inserts double open guillemots; otherwise it checks for a
% `greater than' sign and possibly inserts double closed guillemots;
% otherwise it checks for the slash and possibly it inserts a breakable
% slash |\slash|; otherwise it checks for another double straight quote
% sign and possibly it inserts  double open high quotes (this is useful
% for those keyboards that do not have the `back tick' sign |`|).
%    \begin{macrocode}
\DeclareRobustCommand*{\lt@cwm}{\let\lt@@next\relax

\lt@@next}%
%    \end{macrocode}
%
% This done let's take care of the punctuation. First we create the aliases
% of the punctuation marks with their original category codes

\edef\puntointerrogativo{\string?}\edef\cc@pi{\the\catcode`?}%
%    \end{macrocode}
%
% Then we make those punctuation marks active and add their activeness to

% In this way we are sure that there is no interference with other languages.

% For footnotes we require that the footnote mark be typed flush to the
% left  margin and that it is typed in normal size; this requires the
% redefinition of the |\@makefntext| macro that must call a different
% version of |\@makefnmark|.
%    \begin{macrocode}
%
\let\lt@ori@makefntext\@makefntext
\newcommand\lt@makefntext[1]{%
    \parindent 1em%
    \noindent
    \lt@Makefnmark\enspace #1}
\newcommand\lt@Makefnmark{\hbox{\normalfont\@thefnmark.}}
%    \end{macrocode}
% We add these commands to the |\extraslatin| and |\noextraslatin| lists.
%    \begin{macrocode}
\addto\extraslatin{\let\@makefntext\lt@makefntext}
\addto\noextraslatin{\let\@makefntext\lt@ori@makefntext}
%    \end{macrocode}

% Is this correct? May be not! In a mixed language text footnotes get labelled
% in a different way depending on which language was in force when the
% |\footnote| command was issued. Any solution?
%
% In order to leave the category codes clean we re-establish the default codes 
% reassigning the active cars their initial meaning; we do this by executing
% |\noextraslatin|. If Latin is the default language, or when Latin is
% selected, the |\extraslatin| macro is automatically executed and the original
% category codes reassigned to the active characters.
