-% \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.}%

-%
-% When this file is read as an option, i.e. by the |\usepackage|
-% command, \texttt{latin} will be an `unknown' language in which

- }
-% \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\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.

-% With medieval Latin we need the suitable correspondence between

-%
-% \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

-% \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

-% Notice that the short hand definitions are given only for lower

-% \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.
