[2014/09/08 0.11.2 Greek LICRs for XeTeX and LuaTeX]

Abstract

Experimental support for Greek LICR macros with XeTeX and LuaTeX. Extends euenc. Used by babel-greek and textalpha.

History:

2013-07-16

0.1

initial version

2013-07-18

0.1.1

bugfix: wrong breathings psilioxia -> dasiaoxia

2013-07-19

0.1.2

bugfix: Disable composite defs starting with char macro,
 

fix “hiatus” handling.

2013-07-24

0.1.3

fix “input” path.

2013-10-01

0.1.4

remove clashing defs for legacy characters with oxia,
 

fix upcasing of \finalsigma.

2013-12-01

0.11.1

fix identification.

2014-09-08

0.11.2

\textKoppa macro
 

(Capital Koppa is not defined in LGR but Unicode).

Motivation

LICR macro definitions for the Greek script are missing in both, xunicode and euenc.

This file expands the font encoding definition files eu1enc.def rsp. eu2enc.def from euenc defining LaTeX Internal Character Representaction (LICR) macros for Greek letters and symbols. It works independed of xunicode using the standard commands for LaTeX2e font selection.

Requirements

Requires XeTeX or LuaTeX, euenc (usually loaded via fontspec), and a font with Greek characters.

See greek-euenc-doc.tex and greek-euenc-doc.pdf for setup and usage examples.

Greek Diacritics

Define “named macros” for simple and combined diacritics.

Greek alias names for standard accents:

\DeclareTextCommand{\acctonos}{\LastDeclaredEncoding}{\@tabacckludge'}
\DeclareTextCommand{\accvaria}{\LastDeclaredEncoding}{\@tabacckludge`}
\DeclareTextCommand{\accdialytika}{\LastDeclaredEncoding}{\@tabacckludge"}
\DeclareTextCommand{\accperispomeni}{\LastDeclaredEncoding}{\@tabacckludge~}

Breathings:

(The COMBINING GREEK KORONIS is a legacy character, discarded in favour of COMBINING COMMA ABOVE)

\DeclareTextCommand{\accpsili}{\LastDeclaredEncoding}[1]{#1\char"0313 } % ψιλή spiritus lenis (smooth breathing)
\DeclareTextCommand{\accdasia}{\LastDeclaredEncoding}[1]{#1\char"0314 } % δασεῖα spiritus asper (rough breathing)
\DeclareTextCommand{\>}{\LastDeclaredEncoding}{\accpsili}
\DeclareTextCommand{\<}{\LastDeclaredEncoding}{\accdasia}

Sub-iota:

\ypogegrammeni is a postfix accent (ligature in LGR)

\DeclareTextSymbol{\ypogegrammeni}{\LastDeclaredEncoding}{0837} % COMBINING GREEK YPOGEGRAMMENI

Combined diacritics:

% The COMBINING DIALYTIKA TONOS is discarded and not well supported by fonts:
\DeclareTextCommand{\accdialytikatonos}{\LastDeclaredEncoding}[1]{#1\char"0308 \char"0301 }
\DeclareTextCommand{\accdialytikavaria}{\LastDeclaredEncoding}[1]{#1\char"0308 \char"0300 }
\DeclareTextCommand{\accdialytikaperispomeni}{\LastDeclaredEncoding}[1]{#1\char"0342 \char"0308 }

\DeclareTextCommand{\accdasiaoxia}{\LastDeclaredEncoding}[1]{#1\char"0314 \char"0301 }
\DeclareTextCommand{\accdasiavaria}{\LastDeclaredEncoding}[1]{#1\char"0314 \char"0300 }
\DeclareTextCommand{\accdasiaperispomeni}{\LastDeclaredEncoding}[1]{#1\char"0314 \char"0342 }

\DeclareTextCommand{\accpsilioxia}{\LastDeclaredEncoding}[1]{#1\char"0301 \char"0313 }
\DeclareTextCommand{\accpsilivaria}{\LastDeclaredEncoding}[1]{#1\char"0300 \char"0313 }
\DeclareTextCommand{\accpsiliperispomeni}{\LastDeclaredEncoding}[1]{#1\char"0342 \char"0313 }

Definition with literal Unicode characters, because the code-point has 5 hexadecimal digits:

\DeclareTextCommand{\textpentedeka}{\LastDeclaredEncoding}{𐅄}    % GREEK ACROPHONIC ATTIC FIFTY
\DeclareTextCommand{\textpentehekaton}{\LastDeclaredEncoding}{𐅅} % GREEK ACROPHONIC ATTIC FIVE HUNDRED

UPPERCASE

The common Greek font encoding definitions in greek-fontenc.def extend the uclclist with Greek LICR macros. Here, we add Unicode-specific “hiatus” handling (copied from lgrenc.def and changed Latin transcription to Unicode literals):

\DeclareTextCommand{\LGR@A@hiatus}{\LastDeclaredEncoding}{%
  \LGR@ifnextchar{Ι}{\textAlpha\"}{%
    \LGR@ifnextchar{Υ}{\textAlpha\"}{%
      \LGR@ifnextchar{\textIota}{\textAlpha\"}{%
        \LGR@ifnextchar{\textUpsilon}{\textAlpha\"}{\textAlpha}%
      }%
    }%
  }%
}
\DeclareTextCommand{\LGR@E@hiatus}{\LastDeclaredEncoding}{%
  \LGR@ifnextchar{Ι}{\textEpsilon\"}{%
    \LGR@ifnextchar{Υ}{\textEpsilon\"}{%
      \LGR@ifnextchar{\textIota}{\textEpsilon\"}{%
