+
+Ukrainian language module for Babel, v1.4c
+
+Released under the LaTeX Project Public License v1.3c or later.
+See http://www.latex-project.org/lppl.txt
+
+The package provides support for use of Babel in documents written in Ukrainian. The support is adapted for use both
+under legacy TEX engines, and under X∃TEX and LuaTEX.
+
+Based on Russian language module v1.3i by Igor A. Kotelnikov <kia999 at mail dot ru>.
+
+The current maintainer is Sergiy Ponomarenko <sergiy.ponomarenko@gmail.com>.
+
+
+1. INSTALLATION
+
+- unpack babel-ukrainian.zip
+- run "xelatex.exe ukraineb.dtx" (recommended)
+ or "pdflatex.exe ukraineb.dtx";
+ run "tex.exe ukraineb.dtx"
+ or "tex.exe ukraineb.ins", if you don't need documentation
+- move "ukraineb.ldf" to <textmf>/tex/generic/babel/babel-ukrainian/
+- move "ukraineb.pdf" and README to <textmf>/doc/generic/babel-ukrainian/
+- update filename base (see documentation for your TeX system)
+
+
+2. USAGE
+
+Ukrainian language definition file can be used both with legacy 8-bit engines
+(such as latex.exe or pdflatex.exe) and Unicode compilers (xelatex.exe or
+lualatex.exe). The Unicode engines can be ran either in Unicode mode or 8-bit
+compatibility mode, which emulates the legacy engines. The two modes differ by
+a set of packages loaded in the preamble of a source TeX file. It is important
+to keep recommended order of the packages loaded, especially when running
+Unicode engines in a compatibility 8-bit mode.
+
+In the examples below, it is assumed that a source file has utf8 input encoding.
+
+2.1. 8-bit mode
+
+2.1.1 PDFLATeX, LaTeX
+
+ \usepackage[T1,T2A]{fontenc}
+ \usepackage[utf8]{inputenc}
+ \usepackage[english,ukrainian]{babel}
+
+2.1.2 LuaLaTeX
+
+ \usepackage[T1,T2A]{fontenc}
+ \usepackage[lutf8]{luainputenc}
+ \usepackage[english,ukrainian]{babel}
+
+2.1.3 XeLaTeX
+
+ \XeTeXinputencoding "bytes"
+ \usepackage[utf8]{inputenc}
+ \usepackage[T2A]{fontenc}
+ \usepackage[english,ukrainian]{babel}
+
+2.2 Unicode mode, LuaLaTeX or XeLaTeX
+
+ \usepackage{fontspec}
+ \defaultfontfeatures{Ligatures={TeX}}
+ \setmainfont{CMU Serif}
+ \setsansfont{CMU Sans Serif}
+ \setmonofont{CMU Typewriter Text}
+ \usepackage[english,ukrainian]{babel}
+
+Instead of the Computer Modern Unicode (CMU) fonts loaded in this example,
+you may try any True Type or Open Type font installed on your computer provided
+that that font came with Ukrainian letters.
+
+3. DOCUMENTATION
+
+See ukraineb.pdf for more information.
+
+
+4. KNOWN PROBLEMS
+
+Before switching from a legacy 8-bit engine (tex, pdftex) to an Unicode
+engine (xetex, luatex) and vise versa delete all .aux, .toc, .lot, .lof
+files as they might have stored incompatible internal encodings.

+% \section{The Ukrainian Language Definition File}
+%
+% The file \file{\filename}\footnote{The file described in this document
+% has the version number \fileversion\ and was last revised on \filedate.}
+% is the source file for the Ukrainian Language Definition file
+% \file{\jobname.ldf} to be loaded by the \babel\ package with
+% the option \Lopt{ukrainian}. It's based on the Russian language definition
+% file \file{russianb.ldf} derived by Igor~A.~Kotelnikov.
+%
+% \section{Usage}
+%
+% Typesetting Ukrainian texts implies that a special input and output
+% encodings should be used. Input encodings are those which are used in source
+% (\file{.tex}) file. Output encoding is also known as the font encoding. It is
+% implemented within the font files.
+%
+% Generally, the user may choose between different available Cyrillic
+% encodings. The current support for Cyrillic uses LH family of MetaFont fonts
+% and theirs Postscript versions such as \texttt{CM-super}. Lua\LaTeX\ and Xe\LaTeX,
+% being the Unicode-based succeeders of \LaTeX, allow also for any Open Type
+% (OTF) and True Type (TTF) fonts which has Cyrillic script, e.g. Computer
+% Modern Unicode, Linux Libertine, and many other system fonts that came with
+% Linux, Mac and Windows operating systems.
+%
+% With the advent of Unicode, \LaTeX\ community are moving towards eliminating
+% all existing encodings in favor of Unicode, but nowadays one should take
+% care when switching from \LaTeX\ to Lua\LaTeX\ or Xe\LaTeX\ since
+% different packages should be loaded for those compilers.
+%
+% Since earlier versions \babel{} did not
+% support Xe\LaTeX\ (at least for some languages including Ukrainian), the
+% \pkg{polyglossia} package was generally recommended in the past for
+% use with Xe\LaTeX\ as a replacement for \babel. Nowadays, \babel{}
+% can be used with any engines, including \LaTeX, PDF\LaTeX, Lua\LaTeX, and
+% Xe\LaTeX. Nevertheless some troubles may occur with some languages which
+% have no promptly updated \file{.ldf} files.
+%
+%
+% \subsection{\LaTeX}
+%
+% When user's document is compiled with \file{latex.exe} or \file{pdflatex.exe},
+% recommended set of packages includes the \pkg{inputenc} and \pkg{fontenc}
+% packages. They should be loaded before \babel, for example,
+% \begin{verbatim}
+% \usepackage[T1,T2A]{fontenc}
+% \usepackage[utf8]{inputenc}
+% \usepackage[english,ukrainian]{babel}
+%\end{verbatim}
+% Some variations in the order of loading the packages are allowed in this case
+% but it is better to follow one and the same convention at all circumstances:
+% the \babel{} package should go last, and \pkg{fontenc} must be the first.
+%
+% Input encoding should be declared as option to the \pkg{inputenc}
+% package. Known Cyrillic encodings include \texttt{cp866} (MS DOS),
+% \texttt{cp1251} (Windows), \texttt{koi8-u} (UNIX) and their variants.
+% Nowadays, this list is appended with \texttt{utf8} input encoding.
+%
+% Output encodings (also known as font encodings) are declared as options to
+% the \pkg{fontenc} package. Known Cyrillic encodings are \texttt{T2A},
+% \texttt{T2B}, \texttt{T2C}, \texttt{LCY}, and \texttt{X2};
+% \texttt{LWN} is excluded from Ukrainian support of
+% \file{\filename} since \texttt{LWN} is excluded from the \pkg{cyrillic}
+% bundle of related files.
+%
+%
+% \subsection{Lua\LaTeX}
+%
+% If Unicode fonts are not available, Lua\LaTeX\ can run in compatibility
+% (8-bit) mode to use same font as \LaTeX\ does. However the package
+% \pkg{inputenc} does not work with Lua\LaTeX\ and should be substituted with
+% \pkg{luainputenc}. Source file is to be converted to \texttt{UTF8}
+% (Unicode-8) encoding; it is the only input encoding accepted by
+% Lua\LaTeX. The 8-bit mode is invoked by the following sequence of packages:
+% \begin{verbatim}
+% \usepackage[T1,T2A]{fontenc}
+% \usepackage[lutf8]{luainputenc}
+% \usepackage[english,ukrainian]{babel}
+% \end{verbatim}
+% The order of the packages is crucial for Lua\LaTeX\ in 8-bit mode. Since both
+% \pkg{luainputenc} and \babel{} should know what is a selected font encoding,
+% the \pkg{fontenc} package should be loaded first. Input encoding management for
+% Lua\TeX\ is needed only for compatibility with old documents. For new
+% documents, using UTF-8 encoding and Unicode fonts is strongly recommended.
+% \emph{You've been warned!} See
+% \href{http://tex.stackexchange.com/questions/31709/can-one-instruct-lualatex-to-use-t2a-encoded-fonts}%
+% {tex.stackexchange.com/questions/31709/can-one-instruct-lualatex-to-use-t2a-encoded-fonts}.
+%
+%
+% To invoke Unicode mode, one needs to load the \pkg{fontspec} package instead
+% of \pkg{luainputenc} and \pkg{fontspec} and explicitly indicate which True Type
+% or Open Type fonts should be used for romanic, sans-serif and monospaced types.
+% The following example shows how to load Computer Modern Unicode (CMU) fonts,
+% which is a part of all modern \LaTeX\ distributions:
+% \begin{verbatim}
+% \usepackage{fontspec}
+% \defaultfontfeatures{Renderer=Basic,Ligatures={TeX}}
+% \setmainfont{CMU Serif}
+% \setsansfont{CMU Sans Serif}
+% \setmonofont{CMU Typewriter Text}
+% \usepackage[english,ukrainian]{babel}
+% \end{verbatim}
+% The |\defaultfontfeatures| declares default font features for subsequent
+% |\setmainfont| (which sets romanic fonts), |\setsansfont| (sans-serif) and
+% |\setmonofont| (monospaced font). Font features can be set up on per font
+% bases; for example
+% \begin{verbatim}
+% \usepackage{fontspec}
+% \setmainfont[Renderer=Basic,Ligatures={TeX}]{CMU Serif}
+% \setsansfont[Renderer=Basic,Ligatures={TeX,Historic}]{CMU Sans Serif}
+% \setmonofont{CMU Typewriter Text}
+% \usepackage[english,ukrainian]{babel}
+% \end{verbatim}
+% Here |Renderer=Basic,Ligatures={TeX}| activates ligatures which are existed
+% in \LaTeX.
+%
+% Recall that the language enlisted last in the list of options of the \babel{}
+% package is assumed to be the main language of the document, which is also active
+% language right after |\begin{document}|. As of version 3.9, the main language
+% can be set as a value of the |main| option as follows
+% \begin{verbatim}
+% \usepackage{fontspec}
+% \usepackage[english,main=ukrainian,german]{babel}
+% \end{verbatim}
+% %\unskip
+%
+%
+%
+% \subsection{Xe\LaTeX}
+%
+% In Xe\LaTeX, there is also a special mode for 8-bit compatibility.
+% One can use |\XeTeXinputencoding| to change the input encoding
+% temporarily, and the \texttt{"bytes"} encoding makes Xe\LaTeX\ works
+% like a 8-bit \LaTeX\ engine:
+% \begin{verbatim}
+% \XeTeXinputencoding "bytes"
+% \usepackage[utf8]{inputenc}
+% \usepackage[T2A]{fontenc}
+% \usepackage[english,ukrainian]{babel}
+% \end{verbatim}
+% \unskip
+% Xe\TeX\ can use a different input encoding but it always uses the Unicode
+% internally, so that |\XeTeXinputencoding| performs a conversion of the input
+% into Unicode;
+%
+% \noindent%
+% see \href{http://tex.stackexchange.com/questions/36188/do-xetex-and-luatex-always-use-unicode}
+% {tex.stackexchange.com/questions/36188/do-xetex-and-luatex-always-use-unicode}.
+%
+%
+% Unicode mode is set up same way as for Lua\LaTeX, however the option
+% |Renderer=Basic| can be dropped:
+% \begin{verbatim}
+% \usepackage{fontspec}
+% \defaultfontfeatures{Ligatures={TeX}}
+% \setmainfont{CMU Serif}
+% \setsansfont{CMU Sans Serif}
+% \setmonofont{CMU Typewriter Text}
+% \usepackage[english,ukrainian]{babel}
+% \end{verbatim}
+%
+% \section{User's commands}
+%
+% In a multilingual document, some typographic rules are language
+% dependent and should apply to the whole document.
+%
+% Regarding local typography, the macro |\selectlanguage{ukrainian}|
+% switches to the Ukrainian language, with the following effects:
+% \begin{enumerate}
+% \item Ukrainian hyphenation patterns are made active;
+% \item |\today| prints the date in Ukrainian;
+% \item the caption names are translated into Ukrainian
+% (\LaTeX{} only);
+% \item emdash typed by the ligature |---| might be 20\% shorter when Ukrainian
+% is the current language; the result depends on the current encoding; |---|
+% always produce long emdash in Lua\TeX\ and Xe\TeX\ since these engines
+% use same encodings for all languages;
+% \item emdash typed by the ligature |"---| in Ukrainian is 20\% shorter, however
+% the ligature |"---| might not be defined in other languges; a
+% shorter emdash (i.e. |\cyrdash|) can be typeset in any language using
+% special macros enlisted in table \ref{tab:ukrainian-quote}.
+% \end{enumerate}
+%
+% Additional commands are provided to typeset quotes:
+%
+% \begin{enumerate}
+% \item French quotation marks can be entered using the commands
+% |\guillemotleft| and |\guillemotright| which work in \LaTeXe\
+% and Plain\TeX.
+% \item German quotation marks can be entered using the commands
+% |\glqq| and |\grqq| which work in \LaTeXe\ and Plain\TeX.
+% \end{enumerate}
+%
+% The macro |\Ukrainian| defined as an alias for
+% |\selectlanguage{ukrainian}|, and its ``opponent'' |\English|, existed
+% in \file{\jobname.ldf} has been removed since the Ukrainian
+% language definition file is wrong place for definition of macros which
+% switch to a distinct other language.
+%
+% The macro |\textcyrillic|\marg{text} is intended to typeset small chunks of text
+% in Ukrainian; it is essentially an alias for |\foreignlanguage{ukrainian}|\marg{text}.
+%
+%
+% \subsection{Active character}
+%
+% Table~\ref{tab:ukrainian-quote} shows macros and active string which can be
+% used to typeset various dashes and quotes.
+% In the Ukrainian language, the character |"| is made active. It can be
+% considered as second escape character in addition to |\|. Some dashes and
+% all quotes can be typed using both active character |"| and ordinary
+% macros as indicated in the table. However, some shorthanded hyphenations
+% have no macro counterpart.

+%
+% \medskip
+%
+% The quotation marks traditionally used in Ukrainian were borrowed from
+% other languages (e.g., French and German) so they keep their original
+% names.
+%
+% The French quotes are also available as ligatures `|<<|' and `|>>|' in
+% 8-bit Cyrillic font encodings (\texttt{LCY}, \texttt{X2}, \texttt{T2*})
+% and in Unicode encodings (\texttt{EU1} and \texttt{EU2})
+% and as `|<|' and `|>|' characters in 7-bit Cyrillic font encodings
+% (\texttt{OT2} and \texttt{LWN}).
+%
+% In Unicode encodings \texttt{EU1} and \texttt{EU2} cyrdashes and quotes
+% can be typed as single character if text editor makes it possible to
+% insert characters which absent of standard keyboard. This method works
+% as well for 8-bit fonts encoded according to \texttt{T2A} if source file
+% is encoded with \texttt{cp1251} or {utf8}.
+%
+% By default, active double quote is switched on. It can be switched off
+% any time using |\shorthandoff{"}| and the switched on again using
+% |\shorthandon{"}|.
+%
+% \subsection{Math commands}
+%
+% The \file{\filename} defines few macros that can be used independently
+% of current language. These are macros to be used in math mode to type
+% the names of trigonometric functions common for Ukrainian documents:
+% |\sh|, |\ch|, |\tg|, |\ctg|, |\arctg|, |\arcctg|, |\th|, |\cth|, and
+% |\cosec|. Cyrillic letters in math mode can be typed with the aid of
+% text commands such as |\textbf|, |\textsf|, |\textit|, |\texttt|, e.t.c.
+%
+%
+% \section{\TeX{}nical details}
+%
+% The packages \pkg{inputenc} and \pkg{luainputenc}
+% make Cyrillic letters active so that a compiler converts them into
+% corresponding |\cyr<letter>| macro at compilation time.
+% For example, Ukrainian letter `a' matches
+% macro |\cyra|, and capital Ukrainian letter `A' matches |\CYRA|. The
+% package \pkg{fontenc} then matches every macro |\cyr<letter>| to corresponding
+% glyph in a font file depending on a declared font encoding.
+%
+% Nowadays, Unicode makes |\cyr<letter>| macros outdated since both source
+% file and font file are encoded consistently. These macros
+% should therefore be removed because mixing them with Unicode characters
+% breaks sorting mechanism of such utilities as \file{bibtex} and
+% \file{makeindex}. For the sake of backward compatibility, |\cyr<letter>| are
+% still kept for \LaTeX, but they are bypassed if Lua\LaTeX\ or Xe\LaTeX\
+% are detected.
+%
+% \section{Known problems}
+%
+% Before switching from a legacy 8-bit engine (tex, pdftex) to an Unicode
+% engine (xetex, luatex) and vise versa delete all |.aux|, |.toc|, |.lot|,
+% |.lof| files as they might have stored incompatible internal encodings.

+% \changes{1.3h}{2017/06/06}{Initial version}
+%
+% \subsection{Initial setup}
+%
+% The macro |\LdfInit| performs a couple of standard checks that
+% must be made at the beginning of a language definition file,
+% such as checking the category code of the \texttt{@}-sign, preventing
+% the \file{.ldf} file from being processed twice, etc.
+%
+% \begin{macrocode}
+\LdfInit{ukrainian}{captionsukrainian}
+% \end{macrocode}
+%
+% First, we check if Lua\LaTeX\ or Xe\LaTeX\ is running. If so, we set
+% boolean key |\if@ukr@uni@ode| to true. It will be used to eliminate |\cyr...|
+% commands, which were introduced in \LaTeX2e\ to handle various
+% Cyrillic input encoding. With the advent of Unicode \LaTeX\ is
+% moving to universal input encoding, so we consider these |\cyr...|
+% commands as obsolete. They are preserved though for backward
+% compatibility in case if \LaTeX\ or PDF\LaTeX\ are running.
+%
+% We don't load the \pkg{ifluatex} or \pkg{ifxetex} package because
+% |\RequirePackage| is not allowed at the stage of processing options
+% (note that babel loads this file right when it processes its own options)
+% but we borrow code from these packages.
+%
+% \begin{macrocode}
+\ifdefined\if@ukr@uni@ode
+ \PackageError{babel}{if@ukr@uni@ode already defined.\MessageBreak
+ Please contact author of ukraineb.ldf}
+ \relax
+\fi
+\newif\if@ukr@uni@ode
+\ifdefined\luatexversion
+ \@ukr@uni@odetrue
+\else
+ \ifdefined\XeTeXrevision
+ \@ukr@uni@odetrue
+ \fi
+\fi
+% \end{macrocode}
+%
+% Check if hyphenation patterns for the Ukrainian language have been
+% loaded in \file{language.dat}. Namely, we check for the existence of
+% |\l@ukrainian|. If it is not defined, we declare Ukrainian as dialect
+% for the default language number 0 which almost for sure is English.
+%
+% \begin{macrocode}
+\ifx\l@ukrainian\@undefined
+ \@nopatterns{Ukrainian}
+ \adddialect\l@ukrainian0
+\fi
+% \end{macrocode}
+% Now |\l@ukrainian| is always defined.
+%
+% \subsection{Output encoding}
+%
+% We need to know font encoding that is supposed to be
+% active at the end of the \babel\ package. Default font encoding, set by
+% \LaTeX\ core, is \texttt{OT1}. This can be changed by the \pkg{fontenc}
+% package in case of \LaTeX\ and by \pkg{fontspec} package in case of
+% Lua\LaTeX. It matters weather these packages are loaded before of after
+% \babel. In the latter case or if these packages are not loaded at all,
+% \file{ukraineb.ldf} ignores their effect and tries to provide some
+% reasonable settings. In particular, \texttt{T2A} will be selected for
+% Ukrainian language if \LaTeX\ is running but \texttt{EU1} in case of
+% Xe\LaTeX\ and \texttt{EU2} in case of Lua\LaTeX.
+%
+%
+% In Unicode mode, the package \pkg{fontspec} should be loaded instead of
+% \pkg{fontenc} to make font preparation; \pkg{fontspec} loads the package
+% \pkg{xunicode} which sets current encoding (kept in |\cf@encoding|) to
+% \texttt{EU1} for Xe\LaTeX\ and \texttt{EU2} for Lua\LaTeX, and the \babel{}
+% package sets the macro |\latinencoding| to |\cf@encoding|. Since \babel{} scan
+% for value |\cf@encoding| within |\AtBeginDocument|, |\latinencoding| will
+% be set to either \texttt{EU1} for Xe\LaTeX\ or \texttt{EU2} for Lua\LaTeX\
+% no matter which of the packages, \babel{} or \pkg{fontspec} is loaded first.
+%
+%
+% \Describe\cyrillicencoding{}
+% There is a limited list of encodings appropriate for Cyrillic text. We
+% will look which of them is declared and keep its name in the macro
+% |\cyrillicencoding|.
+% Correct (but obsolete and now deleted) 7-bit Cyrillic encoding is
+% \texttt{LWN}.
+% Correct 8-bit Cyrillic encodings are
+% \texttt{T2A} (default for 8-bit compilers), \texttt{T2B}, \texttt{T2C},
+% \texttt{LCY} and \texttt{X2}.
+% Correct utf8 encodings are
+% \texttt{TU} (default for Xe\LaTeX\ and Lua\LaTeX),
+% \texttt{EU1} (obsolete, formerly used for Xe\LaTeX),
+% \texttt{EU2} (obsolete, formerly used for Lua\LaTeX).
+%
+% In 8-bit (\LaTeX) mode, user may choose between different non-unicode Cyrillic
+% encodings---e.g., \texttt{X2} or \texttt{LCY}.\@ If user wants
+% to use another font encoding rather than default (\texttt{T2A}),
+% he has to load the corresponding file \emph{before} \file{babel.sty}.
+%
+% Remember that for the Ukrainian language, the \texttt{T2A} encoding is
+% better than \texttt{X2}, because \texttt{X2} does not contain Latin
+% letters, and users should be very careful to switch the language
+% every time they want to typeset a Latin word inside a Ukrainian phrase
+% or vice versa.
+%
+% We parse the |\cdp@list| containing encodings known to \LaTeX\
+% in the order they have been loaded by the time \pkg{babel} is called.
+% We set the |\cyrillicencoding| to the \emph{last} loaded encoding in the
+% list of supported Cyrillic encodings: \texttt{OT2}, \texttt{LCY},
+% \texttt{X2}, \texttt{T2C}, \texttt{T2B}, \texttt{T2A}. In Unicode mode,
+% |\cyrillicencoding| is set to \texttt{TU} by \pkg{fontspec}. Nevertheless
+% here we provide similar definitions; 8-bit encodings are kept for Unicode
+% compilers (Lua\LaTeX\ and Xe\LaTeX) since they can run in compatibility
+% (8-bit) mode.

+%
+% \Describe\Ukrainian{}
+% \DescribeOther\cyr{}
+% \DescribeOther\cyrillictext{}
+% For the sake of backward compatibility we keep the macro |\Ukrainian|
+% but redefine its meaning; now |\Ukrainian| is simply an alias for
+% |\selectlanguage{ukrainian}|.
+%
+% We define |\cyrillictext| and its alias |\cyr| but remove another alias
+% |\Ukr|; these macros are intended for use within \texttt{babel} macros and
+% do not perform complete switch of the language.
+% In particular, they to do no switch captions and the name of current
+% language stored in the macro |\languagename|. This inconsistency might
+% break some assumptions embedded into \babel's.
+% For example, the |\iflanguage| macro will fail.
+%
+% Second, |\cyrillictext| does
+% not activate shorthands, so that |"<|, |">|, |"`|, |"'|,
+% |"---|, e.t.c. will not work.
+%
+% And third, |\cyrillictext| does not write its trace
+% to \file{.aux} file, which might result in wrong typesetting of
+% table of content, list of table and list of figures in multilingual
+% documents.
+%
+% Due to any of these reasons the use of the declaration |\cyrillictext| and
+% its aliases in ordinary text is strongly discouraged. Instead of the
+% declaration |\cyrillictext| it is recommended to use |\Ukrainian| or the
+% command |\foreignlanguage| defined in the \babel{} core; their
+% functionality is similar to |\selectlanguage{ukrainian}| but they did not
+% switch caption names, dates and shorthands.
+%
+% \begin{macrocode}
+\DeclareRobustCommand{\Ukrainian}{\selectlanguage{\ukrainian}}
+\DeclareRobustCommand{\cyrillictext}{%
+ \fontencoding\cyrillicencoding\selectfont
+ \let\encodingdefault\cyrillicencoding
+ \expandafter\set@hyphenmins\ukrainianhyphenmins
+ \language\l@ukrainian}%
+\let\cyr\cyrillictext
+% \end{macrocode}
+%
+% \textsc{Next part of code should be moved to \texttt{X2enc.def},
+% \texttt{X2enc.dfu}, if needed.}
+% Since the \texttt{X2} encoding does not contain Latin letters, we
+% should make some redefinitions of \LaTeX\ macros which implicitly
+% produce Latin letters.
+%
+% Unfortunately, the commands |\AA| and |\aa| are not encoding dependent
+% in \LaTeX\ (unlike e.g., |\oe| or |\DH|). They are defined as |\r{A}| and
+% |\r{a}|. This leads to unpredictable results when the font encoding
+% does not contain the Latin letters `A' and `a' (like \texttt{X2}).
+%
+% \begin{macrocode}
+\expandafter\ifx\csname T@X2\endcsname\relax\else

+\fi
+% \end{macrocode}
+%
+%
+% The macro |\cyrillictext| switches current (e.g., Latin) font encoding
+% to a Cyrillic font encoding stored in |\cyrillicencoding|. The macro
+% |\latintext| switches back. This method assumes that an font
+% encoding is a Latin one. But in fact the latter assumption does not matter
+% if any other language is switched on using same method, i.e.
+% if corresponding \file{.ldf} file defines required macros to switch that
+% language on from same standard (Latin) state.
+% Since |\latintext| is defined by the core of babel we do not repeat its
+% definition here.

+% The macros |\cyrillictext| and |\latintext| are declarations.

+% \subsection{Input encoding}
+%
+% User should use the \pkg{inputenc} package when any 8-bit Cyrillic

+% We do not assume any default input encoding, so
+% the \pkg{inputenc} package should be explicitly called by
+% |\usepackage{inputenc}| \emph{before} \babel.

+% \end{macrocode}
+%
+% Initial activation state will set to on later in section \ref{sss:extra}.
+%
+% \Describe\dq{}
+% The active character |"| is used as indicated in
+% table~\ref{tab:ukrainian-quote}. We save the original double quote
+% character in the |\dq| macro to keep it available.
+% The math accent |\"| can now be typed as `|"|'.

+ \def\@SS{\mathchar"7019 }

+% \end{macrocode}
+%
+% \subsubsection{Quotes}
+%
+% We set |"`| and |"'| as shorthands for |\quotedblbase| and
+% |\textquotedblleft|, respectively. These shorthands
+% were defined through german quotes |\glqq| and |\grqq|, which in their turn
+% are defined in \pkg{babel.def} via |\quotedblbase| and |\textquotedblleft|,
+% respectively. It occurred, that old definition caused errors in Unicode
+% mode if \pkg{fontspec} is loaded.
+%
+% The shorthands |"<| and |">| were
+% declared to be equivalents for the French quotes |\flqq| and |\frqq|,
+% respectively. They are defined in \pkg{babel.def} via |\guillemotleft| and
+% |\guillemotrigh|. However, |\flqq| and |\guillemotleft| (and their right
+% counterparts) are typeset differently if current encoding is not
+% \texttt{T1}. Therefore, we define |"<| and |">| directly
+% through |\guillemotleft| and |\guillemotrigh|.
+%
+% \begin{macrocode}
+\declare@shorthand{ukrainian}{"`}{\quotedblbase}
+\declare@shorthand{ukrainian}{"'}{\textquotedblleft}
+\declare@shorthand{ukrainian}{"<}{\guillemotleft}
+\declare@shorthand{ukrainian}{">}{\guillemotright}
+% \end{macrocode}
+%
+% Next set of shorthands is intended for variations of standard macro |\-|
+% which indicates explicitly breakpoint for hyphenation in a word. Meaning
+% of these shorthands is explained in table~\ref{tab:ukrainian-quote}.
+%
+% \begin{macrocode}
+\declare@shorthand{ukrainian}{""}{\hskip\z@skip}

+ \textormath{\nobreak\discretionary{-}{}{\kern.03em}\allowhyphens}{}}
+% \end{macrocode}
+%
+% \subsubsection{Emdash, endash and hyphenation sign}
+%
+% To distinguish between |"-| and |"---| we must check whether the next
+% after |-| token is a hyphen character.
+% If it is, we output an emdash, otherwise a hyphen sign. Therefor
+% \TeX\ looks for the next token after the first `|-|', writes
+% its meaning to |\ukrainian@sh@next| and finally call for |\ukrainian@sh@tmp|.
+%
+% \begin{macrocode}
+\declare@shorthand{ukrainian}{"-}{%
+ \def\ukrainian@sh@tmp{%
+ \if\ukrainian@sh@next-\expandafter\ukrainian@sh@emdash
+ \else%
+ \expandafter\ukrainian@sh@hyphen%
+ \fi}%
+ \futurelet\ukrainian@sh@next\ukrainian@sh@tmp}
+% \end{macrocode}
+% Two macros |\ukrainian@sh@hyphen| and |\ukrainian@sh@emdash| called by
+% |\ukrainian@sh@tmp| are defined below. The second of
+% them has two parameters since it must gobble next two hyphen signs.
+% \begin{macrocode}
+\def\ukrainian@sh@hyphen{\nobreak\-\bbl@allowhyphens}
+\def\ukrainian@sh@emdash#1#2{\cdash-#1#2}
+% \end{macrocode}
+%
+% \Describe\cdash{}
+% In its turn, |\ukrainian@sh@emdash| simply calls for |\cdash| which has
+% rich use. It analyses 3rd of 3 characters and calls for one of few
+% predefined macros |\@Acdash|, |\@Bcdash|, |\@Ccdash|.
+% \begin{macrocode}
+\def\cdash#1#2#3{\def\tempx@{#3}%
+ \def\tempa@{-}\def\tempb@{~}\def\tempc@{*}%

+ \else%
+ \errmessage{Wrong usage of cdash}
+ \fi
+ \fi
+ \fi
+}
+% \end{macrocode}
+%
+% All these 3 internal macros call for |\cyrdash|, which type Cyrillic
+% emdash, but put different spaces around the dash.
+%
+% |\@Acdash| is invoked by |"---|. It types Cyrillic emdash to be used
+% inside a text and puts an unbreakable thin space before the dash if a
+% \textit{space} is placed before |"---| in the source file;
+% can be used after display maths formulae, formatted lists, enumerations, etc.
+% \begin{macrocode}
+\def\@Acdash{\ifdim\lastskip>\z@\unskip\nobreak\hskip.2em\fi
+ \cyrdash\hskip.2em\ignorespaces}%
+% \end{macrocode}
+%
+% |\@Bcdash| is invoked by |"--~|. It types Cyrillic emdash in compound
+% names (like Mendeleev--Klapeiron); requires no space characters around and
+% adds extra space after the dash.
+% \begin{macrocode}
+\def\@Bcdash{\leavevmode\ifdim\lastskip>\z@\unskip\fi
+ \nobreak\cyrdash\penalty\exhyphenpenalty\hskip\z@skip\ignorespaces}%
+% \end{macrocode}
+%
+% |\@Ccdash| is invoked by |"--*|. It denotes direct speech and adds small
+% space after the dash.
+% \begin{macrocode}
+\def\@Ccdash{\leavevmode
+ \nobreak\cyrdash\nobreak\hskip.35em\ignorespaces}%
+% \end{macrocode}
+%
+% \Describe\cyrdash{}
+% The |\cyrdash| macro is defined in Cyrillic font encodings (LCY, T2*, OT2,
+% and |X2|) by means of |\DeclareTextSymbol|. In T2* encodings |\cyrdash|
+% refers to same code point 22 as |\textemdash| does so that these two macros
+% are equivalent. However the dash at the code point 22 have different length
+% in different fonts. The dash in Cyrillic fonts LH is 20\% shorter as
+% compared to Latin fonts such as CM (Computer Modern). As a result, the dash
+% typed by the ligature |---| or its variations mentioned in Table
+% \ref{tab:russian-quote} might change its length after |\selectlanguage|.
+%
+% The |\cyrdash| macro is not available in Latin encodings such as T1. Therefor
+% an explicit or implicit call for |\cyrdash| when current language is English
+% causes an error. For such a case, we provide a fake default. A standard check
+% such as |\ifx\cyrdash\undefined ...\fi| fails to detect absent definitions
+% for Latin encodings since the |\cyrdash| macro is in fact defined. Therefor
+% we use the |\ProvideTextCommandDefault| method:
+% \changes{1.4b}{2017/08/10}{Default for \cs{cyrdash} is provided}
+% \begin{macrocode}
+\PackageInfo{babel}{Default for \string\cyrdash\space is provided}
+%%\ProvideTextCommandDefault{\cyrdash}{\iflanguage{ukrainian}%
+%% {\hbox to.8em{--\hss--}}{\textemdash}}
+\ProvideTextCommandDefault{\cyrdash}{\hbox to.8em{--\hss--}}
+% \end{macrocode}%
+%
+% The |\cyrdash| macro is not defined in the Unicode encoding TU. The fake
+% definition given above cope with this case.
+%
+% Finally, we define a shorthand thin space to be placed between initials
+% as in |D.",Mendeleev|. When used instead of |\,| as in |D.\,Mendeleev|
+% it allows hyphenation in the next word.
+%
+% \begin{macrocode}
+\declare@shorthand{ukrainian}{",}{\nobreak\hskip.2em\ignorespaces}
+% \end{macrocode}
+%
+%
+% \subsection{Switching to and from Ukrainian}
+%
+% Now we define additional macros used to reset current language to
+% Ukrainian and back
+% to some original state. The package \babel{} based on the assumption
+% that original state is characterized by a Latin encoding. Previously,
+% for back reset the macro |\OriginalTeX| was used, but now use |\latintext|
+% for the same purpose.

+% \subsubsection{Caption names}
+%
+% First, we define Ukrainian equivalents for Ukrainian caption names.
+%
+% \Describe\captionsukrainian{}
+% The macro |\captionsukrainian| defines caption names used in the
+% four standard document classes provided with \LaTeX. The macro |\cyr|
+% activates Cyrillic encoding. It could be dropped if we would be sure
+% that Ukrainian captions are called only if current language is Ukrainian.
+% However, the macros such as |\Ukrainian| do not conform to strict rules
+% of the package \babel{} as explained in the above.
+%
+% We now use \babel{}'s 3.9 |\Set<macro>| macro for defining caption names as well
+% as date. If Unicode engine is running, Cyrillic letters are typed
+% in by their Unicode code-points.
+%

+%
+% Ukrainian hyphenation patterns are automatically activated every time

+% |\lefthyphenmin| and |\righthyphenmin|; both are set to~2.

+%
+% \subsubsection{Extra definitions}\label{sss:extra}
+%
+% \Describe\extrasukrainian{}
+% \DescribeOther\noextrasukrainian{}
+% The macro |\extrasukrainian| performs extra definitions in addition to
+% resetting the caption names and date.
+% The macro |\noextrasukrainian| is used to cancel the actions of
+% |\extrasukrainian|.
+%
+%
+% First, we instruct \babel{} to switch font encoding using earlier
+% defined macros |\cyrillictext| and |\latintext|.
+%
+% \begin{macrocode}
+\addto\extrasukrainian{\cyrillictext}
+\addto\noextrasukrainian{\latintext}
+% \end{macrocode}
+%
+% Second, we specify that the Ukrainian group of shorthands should be used.
+%
+% \begin{macrocode}
+\addto\extrasukrainian{\languageshorthands{ukrainian}}
+\addto\extrasukrainian{\bbl@activate{"}}
+\addto\noextrasukrainian{\bbl@deactivate{"}}
+% \end{macrocode}
+%
+% Now the action |\extrasukrainian| has to execute is to make sure that the
+% command |\frenchspacing| is in effect. If this is not the case the
+% execution of |\noextrasukrainian| will switch it off again.
+%
+% \begin{macrocode}
+\addto\extrasukrainian{\bbl@frenchspacing}
+\addto\noextrasukrainian{\bbl@nonfrenchspacing}
+% \end{macrocode}
+%
+% \subsection{Alphabetic enumerations}
+%
+% The traditional alphabetical enumerations in Ukrainan texts use the
+% Cyrillic alphabet (bar several letters). In principle, enumerations are
+% a matter for class and style designers but the same can be said also
+% about things, other than enumerations, such as names of sections and
+% bibliography lists.
+%
+% The alphabet is not the only difference, differences also in the labels format.
+% According to Cyrillic typesetting tradition and also with ДСТУ 3008:2015,
+% label format should be with one right parenthesis and the top level enumerate should be
+% alphabetical, but we believe that this is not necessary
+% for including such changes in \file{\jobname.ldf}, for this purpose you can simply redefine
+% required counters in preamle by common \LaTeX way.
+%
+% \begin{verbatim}
+% \def\theenumi{\alph{enumi}}
+% \def\labelenumi{\theenumi)}
+% \def\theenumii{\alph{enumii}}
+% \def\labelenumii{\theenumii)}
+% \end{verbatim}
+
+%
+% Nevertheless, the Ukrainian \babel{} by default turns on alphabetical enumeration
+% with Cyrillic letters. This means that enumerated lists that would be labelled with
+% Latin letters in Latin scripts are labelled with Cyrillic ones instead.
+%
+% \Describe\Alph{}
+% Starting from this virsion, we remove an macro |\Asbuk|
+% (also it lowercase counterpart |\asbuk|). Now we redefine the macro |\Alph|,
+% which is now produces (uppercase) Cyrillic letters instead of Latin ones
+% when Ukrainian is switched on.
+%
+% The letters Ґ, Є, З, І, Ї, Й, О, Ч, Ь, are skipped for such enumeration (see \href{http://www.uintei.kiev.ua/readarticle.php?article_id=151}{ДСТУ 3008:2015}).
+%
+% \begin{macrocode}
+\addto\extrasukrainian{%
+% \end{macrocode}
+% When Ukrainian swithsed off, the previous meaning of |\@Alph| will be restored
+% \begin{macrocode}
+ \babel@save{\@Alph}%
+ \if@ukr@uni@ode%

+% \end{macrocode}
+% \Describe\alph{}
+% Now the macro |\alph| produces lowercase Cyrillic letters.
+%
+% The lowercase letters ґ, є, з, і, ї, й, о, ч, ь, are also skipped such enumeration (see \href{http://www.uintei.kiev.ua/readarticle.php?article_id=151}{ДСТУ 3008:2015}).

+% \DescribeOther\arctg{}%
+% \DescribeOther\arcctg{}%
+% \DescribeOther\th{}%
+% \DescribeOther\cth{}%
+% \DescribeOther\cosec{}%
+% We also define few math operator names according to Ukrainian mathetematical
+% typography traditions. Some math functions in Ukrainian math books have names
+% different from English writings. For example, \texttt{sinh} in
+% Ukrainian is called \texttt{sh}. Special consideration needs the
+% macro |\th| that conflicts with the text symbol |\th|
+% defined in Latin~1 encoding:
+%
+% \begin{macrocode}
+\def\sh{\mathop{\operator@font sh}\nolimits}
+\def\ch{\mathop{\operator@font ch}\nolimits}
+\def\tg{\mathop{\operator@font tg}\nolimits}
+\def\ctg{\mathop{\operator@font ctg}\nolimits}

+ {\mathop{\operator@font th}\nolimits}}%
+}
+\def\cth{\mathop{\operator@font cth}\nolimits}
+\def\cosec{\mathop{\operator@font cosec}\nolimits}
+% \end{macrocode}
+%
+% For compatibility with older Ukrainian packages we leave definition of the |\No|
+% macro. However the Ukrainian number sign is now superseded with |\textnumero|.
+% Moreover, it can be found on the keyboard.
+% \begin{macrocode}
+\DeclareRobustCommand{\No}{%
+ \ifmmode{\nfss@text{\textnumero}}\else\textnumero\fi}
+% \end{macrocode}
+%
+% \subsection{Final settings}
+%
+% The macro |\ldf@finish| does work needed
+% at the end of each \file{.ldf} file. This
+% includes resetting the category code of the \texttt{@}-sign,
+% loading a local configuration file, and preparing the language
+% to be activated at |\begin{document}| time.
+%
