+% \section{The Latin language}
+%
+% The file \file{\filename}\footnote{The file described in this
+% section has version number \fileversion\ and was last revised on
+% \filedate. The original author is Claudio Beccari with
+% contributions by Krzysztof Konrad \.Zelechowski,
+% (\texttt{kkz@alfa.mimuw.edu.pl})} defines all the
+% language-specific macros for the Latin language both in modern
+% and medieval spelling.
+%
+% For this language the |\clubpenalty|, |\widowpenalty| are set to
+% rather high values and |\finalhyphendemerits| is set to such a
+% high value that hyphenation is prohibited between the last two
+% lines of a paragraph.
+%
+% For this language two ``styles'' of typesetting are implemented:
+% ``regular'' or modern-spelling Latin, and medieval Latin.
+% The medieval Latin specific commands can be activated by means of
+% the language attribute |medieval|; the medieval spelling differs
+% from the modern one by the systematic use of the lower case `u'
+% also where in modern spelling the letter `v' is used; when
+% typesetting with capital letters, on the opposite, the letter 'V'
+% is used also in place of 'U'.
+% Medieval spelling also includes the ligatures |\ae| (\ae), |\oe|
+% (\oe), |\AE| (\AE), and |\OE| (\OE) that are not used in modern
+% spelling, nor were used in the classical times.
+%
+% Furthermore a third typesetting style |withprosodicmarks| is
+% defined in order to use special shortcuts for inserting breves
+% and macrons when typesetting grammars, dictionaries, teaching
+% texts, and the like, where prosodic marks are important for the
+% complete information on the words or the verses. The shortcuts,
+% listed in table~\ref{t:lashrtct} and described in
+% section~\ref{s:shrtcts}, may interfere with other packages;
+% therefore by default this third style is off and no interference
+% is introduced. If this third style is used and interference is
+% experienced, there are special commands for turning on and off
+% the specific short hand commands of this style.
+%
+% For what concerns \textsf{babel} and typesetting with \LaTeX, the
+% differences between the two styles of spelling reveal themselves
+% in the strings used to name for example the ``Preface'' that
+% becomes ``Praefatio'' or ``Pr\ae fatio'' respectively.
+% Hyphenation rules are also different, but the hyphenation pattern
+% file \file{lahyph.tex} takes care of both versions of the
+% language. Needless to say that such patterns must be loaded in
+% the \LaTeX\ format by running |initex| (or whatever the name
+% if the initializer) on |latex.ltx|.
+%
+% The name strings for chapters, figures, tables, etcetera, are
+% suggested by prof. Raffaella Tabacco, a classicist of the
+% University of Turin, Italy, to whom we address our warmest
+% thanks. The names suggested by Krzysztof Konrad \.Zelechowski,
+% when different, are used as the names for the medieval variety,
+% since he made a word and spelling choice more suited for this
+% variety.
+%
+% For this language some shortcuts are defined according to
+% table~\ref{t:lashrtct}; all of them are supposed to work with
+% both spelling styles, except where the opposite is explicitly
+% stated.
+% \begin{table}[htb]\centering
+% \begin{tabular}{cp{80mm}}
+% |^i| & inserts the breve accent as \u{\i}; valid also for the
+% other lowercase vowels, but it does not operate on the
+% medieval ligatures \ae\ and \oe.\\
+% |=a| & inserts the macron accent as \=a; valid also for the
+% other lowercase vowels, but it does not operate on the
+% medieval ligatures \ae\ and \oe.\\
+% |"| & inserts a compound word mark where hyphenation is legal;
+% the next character must not be a medieval ligature \ae\
+% or \oe, nor an accented letter (foreign names).\\
+% \texttt{\string"\string|}
+% & same as above, but operates also when the next character
+% is a medieval ligature or an accented letter.
+% \end{tabular}
+% \caption[]{Shortcuts defined for the Latin language. The
+% characters \texttt{\string^} and \texttt{\string=} are
+% active only when the language attribute
+% \texttt{withprosodicmarks} has been declared,
+% otherwise they are disabled; see
+% section~\ref{s:shrtcts} for more details.}%
+% \label{t:lashrtct}
+% \end{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.
+% \begin{macrocode}
+%<*code>
+\LdfInit{latin}{captionslatin}
+% \end{macrocode}
+%
+% When this file is read as an option, i.e. by the |\usepackage|
+% command, \texttt{latin} will be an `unknown' language in which
+% case we have to make it known. So we check for the existence of
+% |\l@latin| to see whether we have to do something here.
+%
+% \begin{macrocode}
+\ifx\l@latin\@undefined
+ \@nopatterns{Latin}
+ \adddialect\l@latin0\fi
+% \end{macrocode}
+%
+%
+% Now we declare the |medieval| language attribute.
+% \begin{macrocode}
+\bbl@declare@ttribute{latin}{medieval}{%
+ \addto\captionslatin{\def\prefacename{Pr{\ae}fatio}}%
+ \def\november{Nouembris}%
+ \expandafter\addto\expandafter\extraslatin
+ \expandafter{\extrasmedievallatin}%
+ }
+% \end{macrocode}
+%
+% The third typesetting style |withprosodicmarks| is defined here
+% \begin{macrocode}
+\bbl@declare@ttribute{latin}{withprosodicmarks}{%
+ \expandafter\addto\expandafter\extraslatin
+ \expandafter{\extraswithprosodicmarks}%
+ }
+% \end{macrocode}
+% It must be remembered that the |medieval| and the |withprosodicmarks|
+% styles may be used together.
+%
+% The next step consists of defining commands to switch to (and
+% from) the Latin language\footnote{Most of these names were
+% kindly suggested by Raffaella Tabacco.}.
+%
+% \begin{macro}{\captionslatin}
+% The macro |\captionslatin| defines all strings used
+% in the four standard document classes provided with \LaTeX.
+% \begin{macrocode}
+\@namedef{captionslatin}{%
+ \def\prefacename{Praefatio}%
+ \def\refname{Conspectus librorum}%
+ \def\abstractname{Summarium}%
+ \def\bibname{Conspectus librorum}%
+ \def\chaptername{Caput}%
+ \def\appendixname{Additamentum}%
+ \def\contentsname{Index}%
+ \def\listfigurename{Conspectus descriptionum}%
+ \def\listtablename{Conspectus tabularum}%
+ \def\indexname{Index rerum notabilium}%
+ \def\figurename{Descriptio}%
+ \def\tablename{Tabula}%
+ \def\partname{Pars}%
+ \def\enclname{Adduntur}% Or " Additur" ? Or simply Add.?
+ \def\ccname{Exemplar}% Use the recipient's dative
+ \def\headtoname{\ignorespaces}% Use the recipient's dative
+ \def\pagename{Charta}%
+ \def\seename{cfr.}%
+ \def\alsoname{cfr.}% R.Tabacco never saw "cfr. atque" or similar forms
+ \def\proofname{Demonstratio}%
+ \def\glossaryname{Glossarium}%
+ }
+% \end{macrocode}
+% \end{macro}
+% In the above definitions there are some points that might change
+% in the future or that require a minimum of attention from the
+% typesetter.
+% \begin{enumerate}
+% \item the \cs{enclname} is translated by a passive verb, that
+% literally means ``(they) are being added''; if just one
+% enclosure is joined to the document, the plural passive is not
+% suited any more; nevertheless a generic plural passive might be
+% incorrect but suited for most circumstances. On the opposite
+% ``Additur'', the corresponding singular passive, might be more
+% correct with one enclosure and less suited in general: what
+% about the abbreviation ``Add.'' that works in both cases, but
+% certainly is less elegant?
+% \item The \cs{headtoname} is empty and gobbles the possible
+% following space; in practice the typesetter should use the
+% dative of the recipient's name; since nowadays not all such
+% names can be translated into Latin, they might result
+% indeclinable. The clever use of an appellative by the
+% typesetter such as ``Domino'' or ``Dominae'' might solve the
+% problem, but the header might get too impressive. The typesetter
+% must make a decision on his own.
+% \item The same holds true for the copy recipient's name in the
+% ``Cc'' field of \cs{ccname}.
+% \end{enumerate}
+%
+% \begin{macro}{\datelatin}
+% The macro |\datelatin| redefines the command |\today| to produce
+% Latin dates; the choice of faked small caps Latin numerals is
+% arbitrary and may be changed in the future. For medieval latin
+% the spelling of `Novembris' should be \textit{Nouembris}. This is
+% taken care of by using a control sequence which can be redefined
+% when the attribute `medieval' is selected.
+% \changes{latin-2.0f}{2005/03/30}{Added a comment character to
+% prevent unwanted space}

+% \end{macro}
+%
+% \begin{macro}{\romandate}
+% Thomas Martin Widmann (\texttt{viralbus@daimi.au.dk}) developed a
+% macro originally named |\latindate| (but to be renamed
+% |\romandate| so as not to conflict with the standard \babel\
+% conventions) that should compute and translate the current date
+% into a date \textit{ab urbe condita} with days numbered according
+% to the kalendae and idus; for the moment this is a placeholder
+% for Thomas' macro, waiting for a self standing one that keeps
+% local all the intermediate data, counters, etc. If he succeeds,
+% here is the place to add his macro.

+% \end{macro}
+% \end{macro}
+%
+% With medieval Latin we need the suitable correspondence between
+% upper case V and lower case u, since in that spelling there is
+% only one sign, and the u shape is the (uncial) version of the
+% capital V. Everything else is identical with Latin.
+% \begin{macrocode}
+\addto\extrasmedievallatin{%
+ \babel@savevariable{\lccode`\V}%
+ \babel@savevariable{\uccode`\u}%
+ \lccode`\V=`\u \uccode`\u=`\V}
+% \end{macrocode}
+%
+% \begin{macro}{\SetLatinLigatures}
+% We need also the lccodes for \ae\ and \oe; since they occupy
+% different positions in the OT1 \TeX-fontencoding compared to the
+% T1 one, we must save the lc- and the uccodes for both encodings,
+% but we specify the new lc- and uccodes separately as it appears
+% natural not to change encoding while typesetting the same
+% language. The encoding is assumed to be set before starting to
+% use the Latin language, so that if Latin is the default language,
+% the font encoding must be chosen before requiring the \pkg{babel}
+% package with the |latin| option, in any case before any
+% |\selectlanguage| or |\foreignlanguage| command.
+%
+% All this fuss is made in order to allow the use of the medieval
+% ligatures \ae\ and \oe\ while typesetting with the medieval
+% spelling; I have my doubts that the medieval spelling should be
+% used at all in modern books, reports, and the like; the uncial
+% `u' shape of the lower case `v' and the above ligatures were
+% fancy styles of the copyists who were able to write faster with
+% those rounded glyphs; with typesetting there is no question of
+% handling a quill penn\dots Since my (CB) opinion may be wrong, I
+% managed to set up the instruments and it is up to the typesetter
+% to use them or not.

+% \end{macro}
+%
+% \section{Latin shortcuts}\label{s:shrtcts}
+% For writing dictionaries or didactic texts (in modern spelling
+% only) we defined a third language attribute, or a third
+% typesetting style, a couple of other active characters are
+% defined: |^| for marking a vowel with the breve sign, and |=| for
+% marking a vowel with the macro sign. Please take notice that
+% neither the OT1 font encoding, nor the T1 one for most vowels,
+% contain directly the marked vowels, therefore hyphenation of
+% words containing these ``accents'' may become problematic; for
+% this reason the above active characters not only introduce the
+% required accent, but also an unbreakable zero skip that in
+% practice does not introduce a discretionary break, but allows
+% breaks in the rest of the word.
+%
+% It must be remarked that the active characters |^| and |=| may
+% have other meanings in other contexts. For example the equals
+% sign is used by the graphic extensions for specifying keyword
+% options for handling the graphic elements to be included in the
+% document. At the same time, as mentioned in the previous
+% paragraph, diacritical marking in Latin is used only for
+% typesetting certain kind of documents, such as grammars and
+% dictionaries. It is reasonable that the breve and macron active
+% characters are switched on and off at will, and in particular
+% that they are off by default if the attribute |withprosodicmarks|
+% has not been set.
+%
+% \begin{macro}{\ProsodicMarksOn}
+% \begin{macro}{\ProsodicMarksOff}
+% We begin by adding to the normal typesetting style the
+% definitions of the new commands |\ProsodicMarksOn| and
+% |\ProsodicMarksOff| that should produce error messages when the
+% third style is not declared:
+% \begin{macrocode}
+\addto\extraslatin{\def\ProsodicMarksOn{%
+ \GenericError{(latin)\@spaces\@spaces\@spaces\@spaces}%
+ {Latin language error: \string\ProsodicMarksOn\space
+ is defined by setting the\MessageBreak
+ language attribute to `withprosodicmarks'\MessageBreak
+ If you continue you are likely to encounter\MessageBreak
+ fatal errors that I can't recover}%
+ {See the Latin language description in the babel
+ documentation for explanation}{\@ehd}}}
+\addto\extraslatin{\let\ProsodicMarksOff\relax}
+% \end{macrocode}
+%
+% Then we temporarily set the caret and the equals sign to active
+% characters so that they can receive their definitions. But first
+% we store their current category codes to restore them later on.
+% \changes{latin-2.0k}{2008/03/21}{Save current category codes of
+% equals sign and caret in order to restore them later}
+% \begin{macrocode}
+\@tempcnta=\catcode`\=
+\@tempcntb=\catcode`\^
+\catcode`\= \active
+\catcode`\^ \active
+% \end{macrocode}
+% Now we can add the necessary declarations to the macros that are
+% being activated when the Latin language and its typesetting
+% styles are declared:
+% \begin{macrocode}
+\addto\extraslatin{\languageshorthands{latin}}%
+\addto\extraswithprosodicmarks{\bbl@activate{^}}%
+\addto\extraswithprosodicmarks{\bbl@activate{=}}%
+\addto\noextraswithprosodicmarks{\bbl@deactivate{^}}%
+\addto\noextraswithprosodicmarks{\bbl@deactivate{=}}%
+\addto\extraswithprosodicmarks{\ProsodicMarks}
+% \end{macrocode}
+% \end{macro}
+% \end{macro}
+%
+% \begin{macro}{\ProsodicMarks}
+% Next we define the defining macro for the active characters
+% \changes{latin-2.0k}{2008/03/21}{Use \cs{active} instead of 13}
+% \begin{macrocode}
+\def\ProsodicMarks{%
+ \def\ProsodicMarksOn{\catcode`\^ \active\catcode`\= \active}%
+ \def\ProsodicMarksOff{\catcode`\^ 7\catcode`\= 12\relax}%
+% \end{macrocode}
+% Notice that with the above redefinitions of the commands
+% |\ProsodicMarksOn| and |\ProsodicMarksOff|, the operation of the
+% newly defined shortcuts may be switched on and off at will, so
+% that even if a picture has to be inserted in the document by
+% means of the commands and keyword options of the |graphicx|
+% package, it suffices to switch them off before invoking the
+% picture including command, and switched on again afterwards; or,
+% even better, since the picture very likely is being inserted
+% within a |figure| environment, it suffices to switch them off
+% within the environment, being conscious that their deactivation
+% remains local to the environment.
+% \changes{latin-2.0g}{2005/11/17}{changed \cs{allowhyphens} to
+% \cs{bbl@allowhyphens}}
+% \begin{macrocode}
+ \initiate@active@char{^}%
+ \initiate@active@char{=}%
+ \declare@shorthand{latin}{^a}{%
+ \textormath{\u{a}\bbl@allowhyphens}{\hat{a}}}%
+ \declare@shorthand{latin}{^e}{%
+ \textormath{\u{e}\bbl@allowhyphens}{\hat{e}}}%
+ \declare@shorthand{latin}{^i}{%
+ \textormath{\u{\i}\bbl@allowhyphens}{\hat{\imath}}}%
+ \declare@shorthand{latin}{^o}{%
+ \textormath{\u{o}\bbl@allowhyphens}{\hat{o}}}%

+%
+ \declare@shorthand{latin}{=a}{%

+ \declare@shorthand{latin}{=u}{%
+ \textormath{\={u}\bbl@allowhyphens}{\bar{u}}}%
+}
+% \end{macrocode}
+% Notice that the short hand definitions are given only for lower
+% case letters; it would not be difficult to extend the set of
+% definitions to upper case letters, but it appears of very little
+% use in view of the kind of documents where prosodic marks are
+% supposed to be used. Nevertheless in those rare cases when it's
+% required to set some uppercase letters with their prosodic
+% marks, it is always possible to use the standard \LaTeX\ commands
+% such as |\u{I}| for typesetting \u{I}, or |\={A}| for
+% typesetting~\=A.
+%
+% Finally we restore the caret and equals sign initial default
+% category codes.
+% \changes{latin-2.0k}{2008/03/21}{Restore category codes rather then

+% It must be understood that by using the above prosodic marks,

+% are used almost exclusively in dictionaries, grammars, and poems
+% (only in school textbooks), this shouldn't be of any importance
+% for what concerns the quality of typesetting.

+% \section{Etymological hyphenation}
+% In order to deal in a clean way with prefixes and compound words
+% to be divided etymologically, the active character |"| is given
+% a special definition so as to behave as a discretionary break
+% with hyphenation allowed after it.
+% Most of the code for dealing with the active |"| is already
+% contained in the core of \babel, but we are going to use it as a
+% single character shorthand for Latin.
+% \begin{macrocode}
+\initiate@active@char{"}%
+\addto\extraslatin{\bbl@activate{"}%
+}
+% \end{macrocode}
+%
+% A temporary macro is defined so as to take different actions in math
+% mode and text mode: specifically in the former case the macro inserts a
+% double quote as it should in math mode, otherwise another delayed macro
+% comes into action.
+% \begin{macrocode}
+\declare@shorthand{latin}{"}{%
+ \ifmmode
+ \def\lt@@next{''}%
+ \else
+ \def\lt@@next{\futurelet\lt@temp\lt@cwm}%
+ \fi
+ \lt@@next
+}%
+% \end{macrocode}
+% In text mode the \cs{lt@next} control sequence is such that upon
+% its execution a temporary variable \cs{lt@temp} is made
+% equivalent to the next token in the input list without actually
+% removing it. Such temporary token is then tested by the macro
+% \cs{lt@cwm} and if it is found to be a letter token, then it
+% introduces a compound word separator control sequence
+% \cs{lt@allowhyphens} whose expansion introduces a discretionary
+% hyphen and an unbreakable space; in case the token is not a
+% letter, the token is tested again to find if it is the character
+% \texttt{\string|}, in which case it is gobbled and a
+% discretionary break is introduced.
+% \changes{latin-2.0g}{2005/11/17}{Added a \cs{nobreak}}
+% \begin{macrocode}
+\def\lt@allowhyphens{\nobreak\discretionary{-}{}{}\nobreak\hskip\z@skip}
+\newcommand*{\lt@cwm}{\let\lt@n@xt\relax
+ \ifcat\noexpand\lt@temp a%
+ \let\lt@n@xt\lt@allowhyphens
+ \else
+ \if\noexpand\lt@temp\string|%
+ \def\lt@n@xt{\lt@allowhyphens\@gobble}%
+ \fi
+ \fi
+ \lt@n@xt}%
+% \end{macrocode}
+%
+% Attention: the category code comparison does not work if the
+% temporary control sequence \cs{lt@temp} has been let equal to an
+% implicit character, such as |\ae|; therefore this etymological
+% hyphenation facility does not work with medieval Latin spelling
+% when |"| immediately precedes a ligature. In order to overcome
+% this drawback the shorthand \verb!"|! may be used in such cases;
+% it behaves exactly as |"|, but it does not test the implicit
+% character control sequence. An input such as
+% \verb!super"|{\ae}quitas!\footnote{This word does not exist in
+% ``regular'' Latin, and it is used just as an example.} gets
+% hyphenated as \texttt{su-per-{\ae}qui-tas} instead of
+% \texttt{su-pe-r\ae-qui-tas}.
+%
+% 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}
+\ldf@finish{latin}
