+% \noindent This manual documents the \babellatin{} package, which defines
+% all language-specific macros for the \babel{} languages \lang{latin},
+% \lang{classiclatin}, \lang{medievallatin}, and \lang{ecclesiasticlatin}.
+% These languages are usable with pdf\LaTeX, \XeLaTeX, and \LuaLaTeX. The
+% \lang{latin} language is even usable with plain \TeX{} (with some
+% restrictions).

+% Latin has been the most important language of European intellectual life
+% for a long time. Throughout the centuries, many different styles of Latin
+% have been in use concerning wording, spelling, punctuation, and
+% hyphenation. The typographical conventions of an edition of a Latin
+% classic are quite different from those of a liturgical book, even if both
+% have been printed in the 20th century. And even the same Latin text may
+% look quite differently depending on the preferences of the editor and the
+% typographical customs of his country. Latin is supranational, but its
+% typography is not.
+%
+% To fit all needs, the \babellatin{} package defines four different language
+% variants of Latin, i.\,e., four different \babel{} languages.
+% Table \ref{tab:latin-spelling} shows some differences between the language
+% variants.
+% \begin{table}
+% \centering
+% \begin{tabular}{llll}
+% \toprule
+% \lang{latin} & \lang{classiclatin} & \lang{medievallatin} &
+% \lang{ecclesiasticlatin} \\

+% IULIUS & IVLIVS & IVLIVS & IULIUS \\
+% \bottomrule
+% \end{tabular}
+% \caption{\label{tab:latin-spelling}Spelling differences between the
+% Latin language variants}
+% \end{table}
+% It is no problem to use different variants of Latin within the same
+% document. If you need classical and modern Latin, just say
+% \begin{quote}
+% |\usepackage[classiclatin,latin]{babel}|
+% \end{quote}
+% and switch the language using the commands described in the \babel{}
+% manual.
+% \paragraph{The \lang{latin} language -- modern Latin}
+% This language variant is intended for the modern usage of Latin; with this
+% we mean the kind of Latin that is used as an official language in the
+% State of Vatican City and in the teaching of Latin in modern schools.
+% Typically, the following alphabet is used:
+% \begin{center}
+% \setlength\tabcolsep{2pt}
+% \begin{tabular}{*{24}c}
+% a&b&c&d&e&f&g&h&i&k&l&m&n&o&p&q&r&s&t&u&v&x&y&z\\
+% A&B&C&D&E&F&G&H&I&K&L&M&N&O&P&Q&R&S&T&U&V&X&Y&Z
+% \end{tabular}
+% \end{center}
+% \paragraph{The \lang{classiclatin} language -- classical Latin}
+% This language variant is intended for typesetting Latin texts more or less
+% according to the ancient usage of Latin. However, the use of lower-case
+% letters, which are not of ancient origin, is not excluded. The following
+% alphabet is used:
+% \begin{center}
+% \setlength\tabcolsep{2pt}
+% \begin{tabular}{*{23}c}
+% a&b&c&d&e&f&g&h&i&k&l&m&n&o&p&q&r&s&t&u&x&y&z\\
+% A&B&C&D&E&F&G&H&I&K&L&M&N&O&P&Q&R&S&T&V&X&Y&Z
+% \end{tabular}
+% \end{center}
+% Note that `V' corresponds to `u' in lower case. This habit came up in the
+% Middle Ages and is still in use in many text editions. It must be noted
+% that \babellatin{} does not make any spelling correction in order to use
+% only `u' in lower case and only `V' in upper case: if the input text is
+% wrongly typed in, it remains as such; this means it's the typesetter's
+% responsibility to correctly input the source text to be typeset; in spite
+% of this, when the transformation from lower to upper case is performed
+% (such as, for example, while typesetting headers with some document
+% classes) the correct capitalization is performed and `u' is capitalized to
+% `V'; the reverse takes place when transforming to lower case.
+% \paragraph{The \lang{medievallatin} language -- medieval/humanist Latin}
+% The spelling is similar to the classical one, but the ligatures \ae, \AE,
+% \oe, and \OE{} are used for the respective (former) diphthongs. Again, it
+% is the typesetter's responsibility to input the text to be typeset in a
+% correct way. The following alphabet is used:
+% \begin{center}
+% \setlength\tabcolsep{2pt}
+% \begin{tabular}{*{25}c}
+% a&\ae&b&c&d&e&f&g&h&i&k&l&m&n&o&\oe&p&q&r&s&t&u&x&y&z\\
+% A&\AE&B&C&D&E&F&G&H&I&K&L&M&N&O&\OE&P&Q&R&S&T&V&X&Y&Z
+% \end{tabular}
+% \end{center}
+% As far as the current maintainer can judge it, the consequent use of `\ae'
+% and `\oe' ligatures came up in 15th century manuscripts in Italy. So this
+% language variant rather reflects the Latin of the humanist/Renaissance
+% period than that of the Middle Ages. However, we stick to the
+% \emph{medieval} name chosen in earlier versions of \babellatin.
+% \paragraph{The \lang{ecclesiasticlatin} language -- ecclesiastic Latin}
+% Ecclesiastic Latin is a spelling variety of modern Latin, which is used
+% above all in liturgical books of the Roman Catholic Church, where the
+% ligatures \ae{} and \oe{} are widely used and where acute accents are used
+% in order to mark the tonic vowel of words with more than two syllables to
+% make sure the correct stress. The following alphabet is used:
+% \begin{center}
+% \setlength\tabcolsep{2pt}
+% \begin{tabular}{*{26}c}
+% a&\ae&b&c&d&e&f&g&h&i&k&l&m&n&o&\oe&p&q&r&s&t&u&v&x&y&z\\
+% A&\AE&B&C&D&E&F&G&H&I&K&L&M&N&O&\OE&P&Q&R&S&T&U&V&X&Y&Z
+% \end{tabular}
+% \end{center}
+% This language variant also contains a certain degree of ``Frenchization''
+% of spaces around some punctuation marks and guillemets: 1/12 of a quad is
+% inserted before `!', `?', `:', `;', `»', and `›' as well as after `«' and
+% `‹'. The spacing of guillemets does not work with pdf\TeX{} except when
+% using the shorthands |"<| and |">| (see section \ref{shorthands}).
+%
+% \vspace{1.5\bigskipamount}
+% \noindent For what concerns \babel\ and typesetting with \TeX, the
+% differences between the language variants 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, cf.
+% section \ref{hyphenation}.
+%
+% The name strings for chapters, figures, tables, et cetera, have been
+% suggested by prof. Raffaella Tabacco, a latinist of the University of
+% Vercelli, 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.
+%
+% \section{Modifiers}
+% \changes{4.0}{2021/06/27}{New modifiers \modifier{usej},
+% \modifier{lowercasemonth}, and \modifier{ecclesiasticfootnotes}}
+% The four language variants described above do not cover all variations of
+% Latin typography. Additionally there are several \emph{modifiers}:
+% \modifier{usej}, \modifier{lowercasemonth}, \modifier{withprosodicmarks},
+% and \modifier{ecclesiasticfootnotes}. The meaning of these modifiers is
+% explained below.
+%
+% To apply a modifier you have to append it (prefixed with a dot) to the
+% language name when loading \babel:
+% \begin{quote}
+% |\usepackage[ecclesiasticlatin.lowercasemonth]{babel}|
+% \end{quote}
+% If you need two modifiers or more, just concatenate them in arbitrary
+% order:
+% \begin{quote}
+% |\usepackage[latin.usej.withprosodicmarks]{babel}|
+% \end{quote}
+%
+% \subsection{The letter \emph{j}}
+% The letter \emph{j} is not of ancient origin. In early modern times, it
+% was used to distinguish the consonantic \emph{i} from the vocalic
+% \emph{i}. In liturgical books \emph{j} was in use until the 1960s.
+% Nowadays, the use of \emph{j} has disappeared from most Latin
+% publications. This is why \babellatin{} does not use \emph{j} in
+% predefined terms by default. Use the \modifier{usej} modifier if you
+% prefer \emph{Januarii} and \emph{Maji} to \emph{Ianuarii} and
+% \emph{Maii}.
+%
+% \subsection{Case of month names}
+% Traditionally, Latin month names are capitalized: \emph{Ianuarii,
+% Februarii, Martii, \ldots} (We state the genitive forms here as this is
+% what we need for Latin dates.) So \babellatin{} capitalizes the month
+% names for all four language variants. However, in recent liturgical books
+% month names are written in lower case (as in Romance languages). Use the
+% \modifier{lowercasemonth} modifier if you prefer not to capitalize the
+% month names printed by the \cs{today} command: \emph{ianuarii, februarii,
+% martii, \ldots}
+%
+% \subsection{Shorthands for prosodic marks\label{prosodic}}
+% \changes{0.99}{1999/12/06}{Added shorthands for breve and macron}

-% \changes{latin-3.0}{2014/06/01}{Added modifier for classical spelling
+% \changes{4.0}{2021/06/27}{New shorthands for diphthongs with macron}
+% Textbooks, grammars, and dictionaries often use letters with prosodic
+% marks (macrons and breves) like ‘\=a’ and ‘\u{a}’ to mark long
+% and short vowels. On modern systems, the required characters can be input
+% directly thanks to Unicode. For backwards compatibility and as an perhaps
+% more comfortable alternative even today, \babellatin{} provides shorthands
+% for prosodic marks if you load the language with the
+% \modifier{withprosodicmarks} modifier.
+%
+% Note that these shorthands may interfere with other packages. The active
+% |=| character used for macrons will cause problems with commands using
+% |key=value| interfaces, such as the command
+% |\includegraphics[scale=2]{...}|. Therefore, the shorthands are disabled
+% by default. You have to use dedicated commands to turn them on and off.
+% Use \cs{ProsodicMarksOn} to enable them an \cs{ProsodicMarksOff} to
+% disable them again. To get “G\u{a}ll\u{i}\u{a} \u{e}st \u{o}mn\u{i}s
+% d\=iv\=is\u{a} \u{i}n p\u{a}rt\=es tr\=es”, type:
+% \begin{quote}
+% \cs{ProsodicMarksOn}\\
+% |G^all^i^a ^est ^omn^is d=iv=is^a ^in p^art=es tr=es|\\
+% \cs{ProsodicMarksOff}
+% \end{quote}
+%
+% The following shorthands are available:
+% \begin{shorthands}
+% \item[|=a|] for \=a (a with macron), also available for \=e, \=i, \=o,
+% \=u, and \=y
+% \item[|=A|] for \=A (A with macron), also available for \=E, \=I, \=O,
+% \=U, \=V, and \=Y. Note that a macron above the letter V is only
+% displayed if your font supports the Unicode character \unicode{0304}
+% (\emph{combining macron}).
+% \item[|=ae|] for a͞e (ae diphthong with macron, for \lang{latin} and
+% \lang{classiclatin}) or \={\ae} (ae ligature with macron, for
+% \lang{medievallatin} and \lang{ecclesiasticlatin}), respectively; also
+% available for a͞u, e͞u, and o͞e/\=\oe. Note that macrons above diphthongs
+% are only displayed if your font supports the Unicode character
+% \unicode{035E} (\emph{combining double macron}), which always requires
+% \XeLaTeX{} or \LuaLaTeX.\footnote{A good choice for a font supporting
+% the combining double macron might be \emph{Libertinus Serif}, the font
+% of this manual.}
+% \item[|=Ae|] for A͞e (Ae diphthong with macron, for \lang{latin} and
+% \lang{classiclatin}) or \={\AE} (AE ligature with macron, for
+% \lang{medievallatin} and \lang{ecclesiasticlatin}), respectively; also
+% available for A͞u, E͞u, and O͞e/\=\OE.
+% \item[|=AE|] for A͞E (AE diphthong with macron, for \lang{latin} and

+% \lang{medievallatin} and \lang{ecclesiasticlatin}), respectively; also
+% available for A͞U, E͞U, and O͞E/\=\OE.
+% \item[|\textasciicircum a|] for ă (a with breve), also available for
+% ĕ, ĭ, ŏ, ŭ, and y̆. Note that a breve above the letter y is only
+% displayed if your font supports the Unicode character \unicode{0306}
+% (\emph{combining breve}).
+% \item[|\textasciicircum A|] Ă (A with breve), also available for Ĕ, Ĭ,
+% Ŏ, Ŭ, V̆, and Y̆. Note that breves above the letters V and Y are only
+% displayed if your font supports the Unicode character \unicode{0306}
+% (\emph{combining breve}).
+% \end{shorthands}
+% Note the incompatibilities described in section \ref{incompatibilities}.
+%
+% \subsection{Ecclesiastic footnotes}
+% The \package{ecclesiastic} package, an outdated extension of former
+% versions of \babellatin, typeset footnotes with ordinary instead of
+% superior numbers and without indentation.
+%
+% As many ecclesiastic documents and liturgical books use footnotes that are
+% very similar to the ordinary \LaTeX{} ones, we do not use this footnote
+% style as default even for the \lang{ecclesiasticlatin} language variant.
+% But you may use the \modifier{ecclesiasticfootnotes} modifier (with any
+% variant of Latin) if you prefer that footnote style.
+%
+% Note that this modifier affects the entire document. It can only be
+% applied to the document's main language.
+%

-% \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.} defines all the
-% language-specific macros for the Latin language including the classical
-% spelling and hyphenation and the special ecclesiastic spelling.
-%
-% Without modifiers or attributes, this file describes the modern usage
-% of Latin; with this we mean the kind of Latin that is used as an official
-% language in the State of Vatican City, and in the teaching of Latin in
-% modern schools. This file description language accepts several modifiers,
-% in order to be adapted to other situations.
-%\begin{enumerate}\csname c@enumi\endcsname=-1
-%^^A
-%\item Modern spelling and hyphenation; this is the default setting.
-%^^A
-%\item Medieval spelling and hyphenation: in this spelling the lower and
-% upper case alphabets become the following:\\
-%\makebox[\linewidth]{\tabcolsep=2pt
-%\begin{tabular}{*{26}c}
-% a&\ae&b&c&d&e&f&g&h&i&k&l&m&n&o&\oe&p&q&r&s&t&u&x&y&z \\
-% A&\AE&B&C&D&E&F&G&H&I&K&L&M&N&O&\OE&P&Q&R&S&T&V&X&Y&Z
-%\end{tabular}}
-% It must be noted that this file description language does not make
-% any spelling correction in order to use only `u' in lower case and only
-% `V' in upper case: if the input text is wrongly typed in, it remains as
-% such; this means it's the typesetter's responsibility to correctly input
-% the source text to be typeset; in spite of this, when the transformation
-% from lower to upper case is performed (such as, for example, while
-% typesetting headers with some classes) the correct capitalisation is
-% performed and `u' is capitalised to `V'; the reverse takes place when
-% transforming to lowercase.
-%^^A
-%\item Classical Latin and classical hyphenation; the spelling is similar
-% to the medieval one, except for the ligatures \ae, \AE, \oe\ and \OE\
-% that are missing; again it is the typesetter's responsibility to input the
-% text to be typeset in a correct way; while the hyphenation patterns for
-% modern and medieval Latin form a non contrasting set of patterns, this
-% is impossible with classical Latin and a different pattern set has been
-% prepared as explained below.
-%^^A
-%\item Modern spelling with prosodic marks: this is to be used mainly
-% in modern grammars and dictionaries. Its settings can be turned on and
-% off according to the user needs.
-%^^A
-% \item Ecclesiastic Latin is a spelling variety of modern Latin; it is
-% taken care by the external module |ecclesiastic.sty|, that is being loaded
-% by this language description file at the right moment, that is when \babel\
-% has been completely read together with all the options and modifiers.
-% This special spelling of modern Latin is used in theological
-% and devotional books of the Roman Catholic clergy where ligatures \ae\
-% and \oe\ are widely used and where acute accents are used in order to
-% mark the tonic vowel of many words so as to allows clergy with different
-% backgrounds and mother languages to recite their community prayers with
-% the same rhythmic scheme.
-% This ecclesiastic Latin spelling contains also other differences, including
-% a certain degree of ``frenchisation'' of spaces around some punctuation
-% marks and guillemots, and the typesetting style of footnotes.
-% When this spelling is chosen, its features are
-% irrevocable, especially those that concern spacing. And this is the main
-% reason why we decided not to include the ecclesiastic style modifications
-% into the language description file, thus avoiding to mess up any setting
-% for the other Latin typesetting styles.
-%^^A
-%\end{enumerate}
-%
-% Package \babel\ is not directly concerned with hyphenation; nevertheless
-% in this case it is necessary to switch the hyphenation rules to those
-% of another language, |classiclatin|, that must be available
-% while creating the format files so that this language description
-% file can chose between the modern and medieval hyphenation rules or
-% the classical ones.
-%
-% In summary modern and medieval Latin hyphenation rules are similar
-% to those of current Italian, except that the patterns must include
-% also some consonant groups that do not exist in Italian; furthermore
-% with medieval spelling there are many more vocalic groups than in
-% Italian, because of the widespread use of the letter `u' that often
-% actually plays the r\^ole of a consonant.
-%
-% The rules for classical Latin are taken from Raffaello Farina and Nino
-% Marinone's guide \emph{Metodologia} published by Societ\`a Editrice
-% Internazionale, Torino, 1979.
-% In spite of the publication date of this guide the
-% hyphenation rules did not change in the meanwhile, since the Classical
-% Latin Language is sort of frozen during the past, say, twenty
-% centuries. Yes, it is true that the original writings in Classical
-% Latin were not hyphenated, and the hyphenation rules were established
-% at the beginning of the Renaissance, when mechanical typography
-% required suitable justification. Therefore such rules are sort of a
-% compromise between the procedures used by the various proto-typographers
-% and the scholars' of these disciplines. Nevertheless the rules given
-% by Farina and Marinone are generally shared among modern
-% scholars and are sort of official at both universities of Torino
-% and Vercelli; in the latter University they are adopted by the working
-% group that founded the DigilibLT laboratory; I acknowledge their
-% contribution in letting me become aware of the problem, and therefore
-% to create this update by adding the classical Latin support for the
-% \pkg{babel} package, with its special hyphenation rules.
-%
-% In order to implement the above described styles of typesetting,
-% four modifiers/attributes have to be defined: |medieval|, |withprosodicmarks|,
-% |classic|, and |ecclesiastic|. They can be used in any order so that
-% several combinations are possible, although, generally speaking, just
-% the isolated four described ones have a real meaning.
-%
-% Among these modifiers only |withprosodicmarks| can be turned on and off;
-% the others are sort of global; for example, once |classic| is specified,
-% there is no easy way to revert to modern spelling and hypehenation; the
-% same holds true for the other modifiers, except |withprosodicmarks|.
-%
-% The typesetting style |withprosodicmarks| is
-% defined in order to use special shorthands for inserting breves
-% and macrons while typesetting grammars, dictionaries, teaching
-% texts, and the like, where prosodic marks are important for the
-% complete information on the words or the verses. The shorthands,
-% listed in table~\ref{t:lashrtct} and described in
-% subsection~\ref{s:shrtcts}, may interfere with other packages;
-% therefore by default this style is turned off and no interference
-% is introduced. If this style is used and interference is
-% experienced, there are special commands for turning on and off
-% its specific shorthand commands.
-%
-% For what concerns \babel\ and typesetting with \LaTeX, the
-% differences between the spelling styles 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{hyph-la.tex} takes care of the modern and medieval versions
-% of the language, while \file{hyph-la-x-classic.tex} takes care of the
-% classical hyphenation. The user should not attempt to modify these files,
-% because they are not dealt with by \babel\ they are used only during the
-% creation of format files. If some errors or modifications are required
-% or suggested, it is necessary to ask their maintainer.
-%
-% The name strings for chapters, figures, tables, et cetera, have been
-% suggested by prof. Raffaella Tabacco, a latinist of the
-% University of Vercelli, 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 shorthands are defined according to
-% table~\ref{t:lashrtct}; all of them are supposed to work with
-% all spelling styles, except where the opposite is explicitly
-% stated.
-% \begin{table}[htb]\centering

+% \subsection{\package{unicode-math}}
+% Loading the Latin language together with the \modifier{activeacute}
+% \babel{} option may cause error messages if the \package{unicode-math}

+% \url{https://github.com/wspr/unicode-math/issues/462} and
+% \url{https://github.com/reutenauer/polyglossia/issues/394} for related
+% discussions.}
%
+% \subsection{\LuaTeX}
+% The |"| character is made active by \babellatin; its use within the
+% \cs{directlua} command will lead to problems (except in the preamble).
+% Switch the shorthand off for such commands:
+% \begin{quote}
+% |\shorthandoff{"}|\\
+% |\directlua{tex.print("Salve")}|\\
+% |\shorthandon{"}|
+% \end{quote}
+% You may avoid the shorthand switching by using single instead of double
+% quotes. However, note that this will not work if the
+% \modifier{activeacute} option is used, as |'| is active in this case as
+% well.
+%
+% Furthermore, beware of using \cs{directlua} commands containing the |=|
+% character between \cs{ProsodicMarksOn} and \cs{ProsodicMarksOff} if you
+% load the Latin language with the \modifier{withprosodicmarks} modifier.
+%
+% \subsection{\package{babel-turkish}}
+% Both Turkish and Latin (when loaded with the \modifier{withprosodicmarks}
+% modifier) make the |=| character active. However, \babellatin{} takes care
+% the active behaviour of this character is only enabled between
+% \cs{ProsodicMarksOn} and \cs{ProsodicMarksOff} to avoid conflicts with
+% packages using |key=value| interfaces.
+%
+% If you need Latin with prosodic shorthands and Turkish with active |=|
+% character in one document, you have to say |\shorthandon{=}| before the
+% first occurence of |=| in each Turkish text part.

+% \changes{4.0}{2021/06/27}{Basic support for plain \TeX}
+% According to the \babel{} manual, the recommended way to load the Latin
+% language in plain \TeX{} is:
+% \begin{quote}
+% |\input latin.sty|\\
+% |\begindocument|
+% \end{quote}
+% The modifiers \modifier{usej} and \modifier{lowercasemonth} may be
+% accessed by means of the \cs{languageattribute} command:
+% \begin{quote}
+% |\input latin.sty|\\
+% |\languageattribute{latin}{usej,lowercasemonth}|\\
+% |\begindocument|
+% \end{quote}
+%
+% \babel{} does not provide |sty| files for \lang{classiclatin},
+% \lang{medievallatin}, and \lang{ecclesiasticlatin}. It should be possible
+% to create them locally if needed.

+% \begin{macrocode}
+ \providecommand\texorpdfstring[2]{#1}%
+% \end{macrocode}
+% A peculiarity of the \babellatin{} package are shorthands of different

+% we need expl3 syntax for them.
+% \begin{macrocode}
+ \ExplSyntaxOn
+% \end{macrocode}
+% The character |"| is used as a shorthand unconditionally. In math mode it
+% expands to itself. In text mode it is defined as a macro with one
+% parameter. This makes it possible to read the following token, on which
+% the actual meaning of the shorthand depends.
+% \begin{macrocode}
+ \declare@shorthand {latin} {"}
+ {

+ {
+ \texorpdfstring { \babellatin_apply_quotemark:N } { }
+ }
+ }
+% \end{macrocode}
+% The character |'| is used as a shorthand if the \modifier{activeacute}
+% option is used. So we have to use a macro for the declaration, which can
+% be called if necessary. In math mode the shorthand expands to
+% \cs{active@math@prime} as defined in \file{latex.ltx}. In text mode it is
+% a macro with one argument to read the following token.
+% \begin{macrocode}
+ \cs_set_protected:Npn \babellatin@declare@apostrophe@shorthands

+ \declare@shorthand {latin} {'}

+ }
+ }
+ }
+% \end{macrocode}
+% The characters |=| and |^| are only used as shorthands if the
+% \modifier{withprosodicmarks} modifier is used. So we have to use a macro
+% for the declaration, which can be called if necessary. In math mode both
+% shorthands expand to themselves. In text mode they are macros with one
+% argument to read the following token.
+% \begin{macrocode}
+ \cs_set_protected:Npn \babellatin@declare@prosodic@shorthands
+ {
+ \declare@shorthand {latin} {=}

+ {
+ \mode_if_math:TF { \token_to_str:N ^ } { \babellatin_put_breve:N }
+ }
+ }
+% \end{macrocode}
+% The following macro defines the behaviour of the active |"| character.
+% The shorthands |"AE|, |"Ae|, |"ae|, |"OE|, |"Oe|, and |"oe| are used for
+% ligatures if the current variety of Latin uses them. In other cases |"|
+% before any letter character or before |\AE|, |\ae|, |\OE|, and |\oe|
+% defines an additional hyphenation point. \verb:"|: defines an additional
+% hyphenation point as well. The shorthands |"<| and |">| are used for
+% guillemets. In other cases the active |"| character expands to itself and
+% the token read as argument is reinserted.

-% \subsection{Latin shorthands}\label{s:shrtcts}
-% For writing dictionaries or school texts (in modern spelling
-% only) we defined a language attribute or
-% typesetting style, such that a couple of other active characters are
-% defined: |^| for marking a vowel with the breve sign, and |=| for
-% marking a vowel with the macron 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, besides math,
-% 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 kinds of document, such as grammars and
-% dictionaries. It is reasonable that the breve and macron active
-% characters are turned on and off at will; by default
-% they are off 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
-% this style is not declared:
-% \begin{macrocode}
-\addto\extraslatin{\def\ProsodicMarksOn{%

- {See the Latin language description in the babel
- documentation for explanation}{\@ehd}}}
-\addto\extraslatin{\let\ProsodicMarksOff\relax}
-% \end{macrocode}
-%
-% Next we temporarily set the caret and the equals sign to active
-% characters so that they can receive their definitions:
-% \begin{macrocode}
-\catcode`\= \active
-\catcode`\^ \active
-% \end{macrocode}

-% this file is read by \babel\ the current package at the end of which
-% the code is deferred is \babel\ itself, not simply this language description
-% file.
-%
-% Differently from other attribute settings we do not declare anything
-% in a possible |\extrasecclesiasticlatin| macro, because once the package
-% has been read, it is impossible to pretend to delete all what the package
-% defined. Actually this |ecclesiastic| attribute simply mimics the actual

-% \subsection{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. You may consider this sign as a
-% substitute for a ``compound word mark''.
-%
-% This is particularly useful with classical Latin because this
-% language requires etymological hyphenation; patterns were created
-% with etymological hyphenation in mind, but even if for certain
-% prefixes or suffixes it works pretty well, it does not for certain
-% other ones. For example the word `redire' should be hyphenated as
-% `red-i-re'; but there are plenty of other words starting with the
-% string `red' that does not play the role of a prefix; therefore
-% it should be necessary to extract all the Latin words where `red'
-% is a prefix, and enter the suitable patterns to hyphenate correctly
-% only those words; in the simple case of the verb `redire' it would
-% be necessary to enter all the words that belong to the conjugation
-% of this verb and the declination of the present, future and past
-% participles and gerundive in masculine, feminine and neutral forms;
-% the same problem takes place with prefix `trans' where sometimes it is
-% a real prefix, such as in `transire' (hyphenation trans-i-re), and
-% sometimes is modified with the absorption of an initial `s' of the
-% suffix, such as in `transubstantialis' (classical hyphenation:
-% tran-subs-tan-tia-lis).
-
-% Obviously this task would render the pattern file enormous, and mostly
-% useless. The active character |"| solves the problem for isolated instances,
-% while the hyphenations exception lists of the only forms actually used
-% in a specific document, would do the rest.
-%
-% 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

+% are treated the same way as letter characters in most cases. However, in

+% \begin{macrocode}
+\bbl@declare@ttribute\CurrentOption{usej}{%
+ \expandafter\addto\csname extras\CurrentOption\endcsname{%

+% \end{macrocode}
+% \subsubsection{Typesetting months in lower case}

+% \cs{ifbabellatin@lowercasemonth} to true.
+% \begin{macrocode}

+ \babellatin@lowercasemonthtrue}%
+ \expandafter\addto\csname noextras\CurrentOption\endcsname{%
+ \babellatin@lowercasemonthfalse}%
+}%
+% \end{macrocode}
+% \subsubsection{Shorthands for prosodic marks}
+% The \modifier{withprosodicmarks} option makes it possible to use
+% shorthands like |=a| or |^a| for vowels with macrons and breves. We define
+% it for all four language variants of Latin, but only if the \LaTeX{}
+% format is used.
+% \begin{macrocode}
+\ifx\fmtname\babellatin@latex
+ \bbl@declare@ttribute\CurrentOption{withprosodicmarks}{%
+% \end{macrocode}
+% Every shorthand character needs an \cs{initiate@active@char} command,
+% which makes the respective character active, but expanding to itself as
+% long as no further definitions occur. Both active characters needs to be
+% switched off at the beginning of the document to avoid problems with
+% commands using |key=value| interfaces (e.\,g.\@ \cs{includegraphics}) and
+% \TeX's |^^xx| convention.
+% \begin{macrocode}
+ \initiate@active@char{=}%
+ \initiate@active@char{^}%

+% \end{macrocode}
+% We do not use |\shorthandoff{=}| and |\shorthandoff*{^}| in the following
+% lines because \package{babel-french} redefines the \cs{shorthandoff}
+% command for \XeLaTeX{} and \LuaLaTeX. Instead, we use \babel's internal
+% definition of this command.
+% \begin{macrocode}
+ \bbl@shorthandoff\z@{=}%
+% \end{macrocode}
+% The following line is currently uncommented because switching |^| off and
+% on does not work as expected.\footnote{See

+% The active |=| and |^| are normally turned off to avoid problems with
+% commands using |key=value| interfaces and \TeX's |^^xx| convention. We
+% define the commands \cs{ProsodicMarksOn} and \cs{ProsodicMarksOff} for
+% turning them on and off within the document. We use the starred form of
+% \cs{shorthandoff} when turning off |^| to keep it working within math
+% formulas.
+% \begin{macrocode}

+local function process(head)
+ local current = head
+ while current do
+ local id = current.id
+ if id == glyph_code then
+ if has_attribute(current, punct_attr) then
+% \end{macrocode}
+% We try to obtain the character of the current node from its property
+% table, which is the most reliable way as the same character may be
+% rendered by different glyphs with different code numbers.
+% \begin{macrocode}
+ local char = get_property(current) and get_property(current).glyph_info
+% \end{macrocode}
+% If the |glyph_info| property is not available, we use the node's |char|
+% field to obtain the character, which is however only possible for numbers
+% up to 10FFFF\textsubscript{16}.
+% \begin{macrocode}
+ if not char and current.char <= 0x10FFFF then
+ char = utf8.char(current.char)
+ end
+ local leftspace, rightspace
+ if char then
+ leftspace = left_space[char]
+ rightspace = right_space[char]
+ end
+ if leftspace or rightspace then
+ local fontparameters = fonts.hashes.parameters[current.font]
+ local spacing_node
+ if leftspace and fontparameters then
+ local prev = get_prev(current)
+ local space_exception = false
+ if prev then
+% \end{macrocode}
+% We do not add space after left (opening) brackets and between question/exclamation marks:
+% \begin{macrocode}
+ space_exception = someleftbracket(prev)
+ or question_exclamation_sequence(prev, current)
+ while somespace(prev) do
+ head = remove_node(head, prev)
+ prev = get_prev(current)
+ end
+ if somepenalty(prev, 10000) then
+ head = remove_node(head, prev)
+ end
+ end
+ spacing_node = get_kern_node(leftspace * fontparameters.quad)
+ if not space_exception then
+ head = insert_node_before(head, current, spacing_node)
+ end
+ end
+ if rightspace and fontparameters then
+ local next = get_next(current)
+ local space_exception = false
+ if next then
+% \end{macrocode}
+% We do not add space before right (closing) brackets:
+% \begin{macrocode}
+ space_exception = somerightbracket(next)
+ local nextnext = get_next(next)
+ if somepenalty(next, 10000) and somespace(nextnext) then
+ head, next = remove_node(head, next)
+ end
+ while somespace(next) do
+ head, next = remove_node(head, next)
+ end
+ end
+ spacing_node = get_kern_node(rightspace * fontparameters.quad)
+ if not space_exception then
+ head, current = insert_node_after(head, current, spacing_node)
+ end
+ end
+ end
+ end
+ elseif id == math_code then
+ current = end_of_math(current)
+ end
+% \end{macrocode}
+% The following line does not cause an error even if |current| is |nil|.
+% \begin{macrocode}
+ current = get_next(current)
+ end
+ return head
+end
+% \end{macrocode}
+% Now we define the actual amount of space for the relevant punctuation
+% characters. For ecclesiastic Latin (and sometimes for Italian) a very
+% small space is used for the punctuation. The ecclesiastic package, a
+% predecessor of the current \babellatin{}, used a space of
+% 0.3|\fontdimen2|, where |\fontdimen2| is an interword space, which is
+% typically between 1/4 and 1/3 of a quad. We choose a half of a
+% |\thinspace| here, i.\,e., 1/12 of a quad.
+% \begin{macrocode}
+local hairspace = 0.08333 -- 1/12
+local function space_left(char)
+ left_space[char] = hairspace
+end
+local function space_right(char, kern)
+ right_space[char] = hairspace
+end
+space_left('!')
+space_left('?')
+space_left('‼')
+space_left('⁇')
+space_left('⁈')
+space_left('⁉')
+space_left('‽') -- U+203D (interrobang)
+space_left(':')
+space_left(';')
+space_left('»')
+space_left('›')
+space_right('«')
+space_right('‹')
+% \end{macrocode}
+% The following functions activate and deactivate the punctuation spacing.
+% \begin{macrocode}
+local function activate()
+ tex.setattribute(punct_attr, 1)
+ for _, callback_name in ipairs{ "pre_linebreak_filter", "hpack_filter" } do
+ if not in_callback(callback_name, "ecclesiasticlatin-punct.process") then
+ add_to_callback(callback_name, process, "ecclesiasticlatin-punct.process", 1)
+ end
+ end
+end
+local function deactivate()
+% \end{macrocode}
+% Though it would make compilation slightly faster, it is not possible to
+% safely remove the process from the callback here. Imagine the following
+% case: you start a paragraph by some spaced punctuation text, then, in the
+% same paragraph, you change the language to something else, and thus call
+% this function. This means that, at the end of the paragraph, the function
+% won't be in the callback, so the beginning of the paragraph won't be
+% processed by it. So we just unset the attribute.
+% \begin{macrocode}
+ tex.setattribute(punct_attr, -0x7FFFFFFF) -- this value means "unset"
+end
+% \end{macrocode}
+% For external access to the activation and deactivation of the punctuation
+% spacing, we define two functions with the prefix |ecclesiasticlatin|.
+% \begin{macrocode}
+ecclesiasticlatin = ecclesiasticlatin or {}
+ecclesiasticlatin.activate_spacing = activate
+ecclesiasticlatin.deactivate_spacing = deactivate
+% \end{macrocode}
