% :Copyright: © 2013 Günter Milde
% :Licence: This work may be distributed and/or modified under the
% conditions of the `LaTeX Project Public License`_, either
% version 1.3 of this license or any later version.
%
% :Abstract: This file provides definitions that are shared between
% font encodings providing Greek characters.
%
% Changelog
% ---------
%
% .. class:: borderless
%
% ===== ============ ========================================================
% 0.9 2013-07-03 code "outsourced" from lgrxenc.def
% 0.9.1 2013-07-17 composite definitions starting with standard accent cmds
% ===== ============ ========================================================
%
% Usage
% -----
%
% This file can be input by font encoding definition files after declaring the
% font encoding.
%
% Example:
% Define Greek LICR's for XeTeX
%
% .. code:: latex
%
% \DeclareFontEncoding{EU1}{}{}
% \input{greek-fontenc.def}
% % Unicode-specific LICR - Character mappings
% % ...
%
%
% Implementation
% --------------
%
% Identification
% ~~~~~~~~~~~~~~
% ::
\ProvidesFile{greek-fontenc.def}
[2013/07/18 v0.9.1 Common Greek font encoding definitions]
% Ensuregreek
% ~~~~~~~~~~~
%
% The ``\ensuregreek`` command 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. ::
\DeclareTextCommand{\ensuregreek}{\LastDeclaredEncoding}[1]{#1}
% Aliases
% ~~~~~~~
%
% Compatibility aliases for hyperref_'s puenc.def, defined via
% `DeclareTextCommand` so that up/downcasing works without the need for
% additional uclclist entries::
\DeclareTextCommand{\textstigmagreek}{\LastDeclaredEncoding}{\textstigma}
\DeclareTextCommand{\textkoppagreek}{\LastDeclaredEncoding}{\textkoppa}
\DeclareTextCommand{\textStigmagreek}{\LastDeclaredEncoding}{\textStigma}
\DeclareTextCommand{\textSampigreek}{\LastDeclaredEncoding}{\textSampi}
\DeclareTextCommand{\textsampigreek}{\LastDeclaredEncoding}{\textsampi}

\DeclareTextCommand{\textnumeralsigngreek}{\LastDeclaredEncoding}{\textdexiakeraia}
\DeclareTextCommand{\textnumeralsignlowergreek}{\LastDeclaredEncoding}{\textaristerikeraia}
% Two Unicode names for one character::
\DeclareTextCommand{\accoxia}{\LastDeclaredEncoding}{\acctonos}
\DeclareTextCommand{\acckoronis}{\LastDeclaredEncoding}{\accpsili}
% Symbol macros for the breathings::
\DeclareTextCommand{\<}{\LastDeclaredEncoding}{\accdasia}
\DeclareTextCommand{\>}{\LastDeclaredEncoding}{\accpsili}
% TODO: do we also want alternative symbols for the breathings (cf. X compose
% table, LCI encoding)?
%
% .. code:: latex
%
% \DeclareTextCommand{\(}{\LastDeclaredEncoding}{\accdasia}
% \DeclareTextCommand{\)}{\LastDeclaredEncoding}{\accpsili}
%
% Names from babel_ and teubner_ (do we want to define them here as alias?)

% \DeclareTextCommand{\katwtonos}{\LastDeclaredEncoding}{\textaristerikeraia} % ͵
%
%
% Composite diacritics
% ~~~~~~~~~~~~~~~~~~~~
%
% Composite accents can be input as sequence of simple diacritics (in
% arbitrary order) via named macro, symbol macro and "transcription
% characters", e.g. one of
%
% .. code:: latex
%
% \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 "transcription 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::
