  [2023/03/08 2.2.1 Common Greek font encoding definitions]

% ensuregreek, greekscript
% ~~~~~~~~~~~~~~~~~~~~~~~~
%
% Provide "empty" encoding-specific definitions for ``\ensuregreek`` and
% ``\greekscript``. The definitions in this file make the font encoding fit
% for use with the Greek script. (See ``textalpha.sty`` for default
% definitions.)
%
% The ``\ensuregreek`` macro can be used to ensure that its argument is set
% in a font encoding with support for Greek. If the active font encoding
% supports it, kerning between adjacent command calls (e.g.
% ``\ensuregreek{A}\ensuregreek{\Upsilon}``) is preserved. This allows, e.g.,
% wrapping of compound Unicode character definitions. ::

\ProvideTextCommand{\ensuregreek}{\LastDeclaredEncoding}{\@firstofone}

% The ``\greekscript`` declaration switches to a font encoding supporting
% the Greek script, if required. The following definition announces the
% ``\LastDeclaredEncoding`` as Greek-supporting::

\ProvideTextCommand{\greekscript}{\LastDeclaredEncoding}{}


% Aliases
% ~~~~~~~
%
% Aliases are defined via `DeclareTextCommand` so that up/downcasing works
% without the need for additional uclclist_ entries.
%
%
% Names matching mathematical variant symbols::

% \var... matching GREEK ... SYMBOL
\DeclareTextCommand{\textvarbeta}{\LastDeclaredEncoding}{\textbetasymbol}   % ϐ
\DeclareTextCommand{\textvarkappa}{\LastDeclaredEncoding}{\textkappasymbol} % ϰ
\DeclareTextCommand{\textvarTheta}{\LastDeclaredEncoding}{\textThetasymbol} % ϴ
\DeclareTextCommand{\textvartheta}{\LastDeclaredEncoding}{\textthetasymbol} % ϑ
\DeclareTextCommand{\textvarpi}{\LastDeclaredEncoding}{\textpisymbol}       % ϖ

% Names from babel_ and teubner_ (do we want to define them here as alias?)
%
% .. code:: latex
%
%   \DeclareTextCommand{\anwtonos}{\LastDeclaredEncoding}{\textdexiakeraia}     % ʹ
%   \DeclareTextCommand{\katwtonos}{\LastDeclaredEncoding}{\textaristerikeraia} % ͵
%
% Two Unicode code points and names for one character::

\DeclareTextCommand{\accoxia}{\LastDeclaredEncoding}{\acctonos}
\DeclareTextCommand{\accdialytikaoxia}{\LastDeclaredEncoding}{\accdialyikatonos}
\DeclareTextCommand{\acckoronis}{\LastDeclaredEncoding}{\accpsili}

% Symbol macros for the breathings:
%
% Moved to ``textalpha.sty`` to avoid clashes with local definitions
% of ``\<`` and ``\>`` in documents using LGR or babel-greek.
% (Bugreport David Kastrup). If you want to use the short macros without
% loading `textalpha`, you can define them in the document preamble like
%
% .. code:: latex
%
%   \DeclareTextCommand{\<}{LGR}{\accdasia}
%   \DeclareTextCommand{\>}{LGR}{\accpsili}
%   \DeclareTextCompositeCommand{\>}{LGR}{'}{\accpsilioxia}
%   \DeclareTextCompositeCommand{\>}{LGR}{`}{\accpsilivaria}
%   \DeclareTextCompositeCommand{\>}{LGR}{~}{\accpsiliperispomeni}
%   \DeclareTextCompositeCommand{\<}{LGR}{'}{\accdasiaoxia}
%   \DeclareTextCompositeCommand{\<}{LGR}{`}{\accdasiavaria}
%   \DeclareTextCompositeCommand{\<}{LGR}{~}{\accdasiaperispomeni}
%
% Or use alternative symbols for the breathings (cf. X compose
% table, LCI encoding)?
%
% .. code:: latex
%
%   \DeclareTextCommand{\(}{\LastDeclaredEncoding}{\accdasia}
%   \DeclareTextCommand{\)}{\LastDeclaredEncoding}{\accpsili}
%
% Composite diacritics
% ~~~~~~~~~~~~~~~~~~~~
%
% Composite accents can be input as sequence of simple diacritics (in
% arbitrary order) via named macro, symbol macro and "transliteration
% characters", e.g. one of
%
% .. code:: latex
%
%   \accdialyticavaria\textalpha,
%   \accdialytica\accvaria\textalpha,
%   \"\'\textalpha,
%   \"'\textalpha, or
%   \'"\textalpha.
%
% Separate definitions for the supported variants of the second input token
% are required as composition is based on the non-expanded input
%
% The composition with simple "transliteration characters" must also be defined
% for the symbol macros, otherwise it fails with ``\Makeuppercase``.
%
% For Unicode encodings (where they do not resolve to Greek named macros),
% composite definitions starting with standard macros are requried::

%
% UPPERCASE
% ~~~~~~~~~
%
% UPPERCASE (all-caps) is generated with ``\MakeUppercase``. The
% implementation of this command changed in June 2022 [ltnews35]_.
%
% According to Greek typographical tradition, diacritics (except dialytika,
% iota subscript, macron, and breve) are placed before capital letters in
% Titlecase and dropped in UPPERCASE.
%
% Different conventions exist for the treatment of the `mute iota`_ with
% uppercase letters. The traditional typographic form and the most common
% used in Greece is a subscript, corresponding to the COMBINING GREEK
% YPOGEGRAMMENI (U+0345). Even if the pre-composed characters are named ...
% WITH [... AND] PROSGEGRAMMENI, capitalization should not use the GREEK
% PROSGEGRAMMENI (U+1FBE) [Nicholas-03]_, [Haralambous-98]_.  Upper case
% glyphs with adscript are a stylistic choice, provided by the font. In the
% CB Fonts, a small capital adscript iota is used.
%
% Up to 2022/06, macro substitutions in the ``\@uclclist`` could be used to
% get the expected behaviour:
%
%
% @uclclist extension
% """""""""""""""""""
%
% Based on Werner Lemberg's 2008 `babel patch`_ and ``fontenc.sty``.
%
% The definition of an auxiliary, self-resetting macro makes this idempotent
% (only the first use of this function will expand the ``@uclclist``).
% The second and third lines are TeX' way of writing ``uclclist += …``
%
% The ``\LGR@…`` auxiliary macros are defined below.
