[Tex/LaTex] Hyphenation of bibliographies with multiple languages using xelatex,xgreek and biblatex

biblatexhyphenationlanguagesxetex

I am trying to use XeLaTeX to produce a document written in Greek that includes both
English and Greek bibliography.

i am using for this purpose a combination of xgreek, biblatex packages and biber.

The problem that I have is that xelatex seems to ignore the hyphenation field in the bib.
Here is an example of the style file i am using:

\RequirePackage{xltxtra}  % loads fixltx2e, etex, xunicode, fontspec
\RequirePackage{xgreek}   % for greek documents
\RequirePackage[language=greek,backend=biber,
bibencoding=utf8,natbib=true,bibstyle=authoryear,
citestyle=authoryear,babel=hyphen]{biblatex}

and here is an example of the bibliography:

@article{Ritchie_07,
Author = {Bob Ritchie and Esamaddin Khorwatt},
Journal = {The English Accounting Review},
Hyphenation = {english},
Language = {english},
Pages = {39--59},
Title = {The attitude of Libyan auditors to inherent control risk assessment},
Volume = {39},
Year = {2007}}

The problem is that I can have either hyphenation of greek bibliographies and not english,
or vice-versa. I can't have both.

I am using MikTeX 2.8. Any feedback will be greatly appreciated

To switch between different languages in the bibliography, biblatex uses babel's or polyglossia's macro \selectlanguage. xgreek seems to be similar to babel and polyglossia, but it doesn't define \selectlanguage.

You can try to put

\RequirePackage{polyglossia}
\newfontfamily\greekfont[Script=Greek]{Gentium} % or other font with support for greek
\setmainlanguage[variant=monotonic]{greek} % variant can be polytonic, monotonic, or ancient 
\setotherlanguage{english} % you need to put here \setotherlanguage for each language that you are using in the bibliography

to your style file instead of xgreek. Study polyglossia manual for more details.

maybe try to remove some unnecessary options of biblatex:

\RequirePackage[
  backend=biber
 ,bibencoding=utf8
 ,natbib=true
 ,style=authoryear
 ,babel=hyphen
]{biblatex}

part of problem was, that you have explicitly set bibliography language to greek.

[Tex/LaTex] In LuaTex is it possible to change font/language according to the script/glyphs used

Here is a proof of concept at doing the equivalent of \XeTeXinterchartoks in luatex.

First, a style file:

    % luatexinterchartoks.sty
\newcount\XeTeXinterchartokenstate

\newcount\charclasses
\def\newXeTeXintercharclass#1%
  {\global\advance\charclasses1\relax
   \newcount#1
   \global#1=\the\charclasses
   }

\newcount\cchone
\newcount\cchtwo

\def\dodoXeTeXcharclass
    {\directlua{setcharclass(\the\cchone,\the\cchtwo)}}

\def\doXeTeXcharclass%
   {\afterassignment\dodoXeTeXcharclass\cchtwo }

\def\XeTeXcharclass%
   {\afterassignment\doXeTeXcharclass\cchone }

\protected\def\XeTeXdointerchartoks%
   {\directlua{setinterchartoks(\the\cchone,\the\cchtwo,\the\allocationnumber)}}

\protected\def\dodoXeTeXinterchartoks%
   {\newtoks\mytoks\afterassignment\XeTeXdointerchartoks\global\mytoks }

\protected\def\doXeTeXinterchartoks%
   {\afterassignment\dodoXeTeXinterchartoks\cchtwo }

\def\XeTeXinterchartoks%
   {\afterassignment\doXeTeXinterchartoks\cchone }

\luatexdirectlua{dofile('luatexinterchartoks.lua')}

\endinput

And a matching lua file:

% luatexinterchartoks.lua

charclasses = charclasses or {}

function setcharclass (a,b)
   charclasses[a] = b
end

local i = 0
while i < 65536 do
  charclasses[i]  = 0
  i = i + 1
end

interchartoks =  interchartoks or {}

function setinterchartoks (a,b,c)
   interchartoks[a] = interchartoks[a] or {}
   interchartoks[a][b] = c
end

local nc, oc
oc = 255

function do_intertoks () 
  local tok = token.get_next() 
  if tex.count['XeTeXinterchartokenstate'] == 1 then
      if tok[1] == 11 or  tok[1] == 12 then
        nc = charclasses[tok[2]] 
        newchar = tok[2]
      else 
        nc = 255
        newchar = ''
      end
      local insert  = ''
      if interchartoks[oc] and interchartoks[oc][nc] then
          insert = interchartoks[oc][nc] 
          local newtok = tok
          if insert<100 then
            local dec = math.floor(insert / 10) + 48;
            local unit = math.floor(insert % 10) + 48;
            newtok = {
              -- \XeTeXinterchartokenstate=0 \the\toks<n> \XeTeXinterchartokenstate=1
              token.create('XeTeXinterchartokenstate'),
              token.create(string.byte('='),12),
              token.create(string.byte('0'),12),
              token.create(string.byte(' '),10),
              token.create('the'),
              token.create('toks'),
              token.create(dec,12),
              token.create(unit,12),
              token.create(string.byte(' '),10),
              token.create('XeTeXinterchartokenstate'),
              token.create(string.byte('='),12),
              token.create(string.byte('1'),12),
              token.create(string.byte(' '),10),
              {tok[1], tok[2], tok[3]}}               
          end
          tok = newtok
      end
      oc = nc
  end
  return tok
end

callback.register ('token_filter', do_intertoks)

And a test document:

\documentclass{article}

\usepackage{luatexinterchartoks}
\usepackage{color}

\begin{document}

\newXeTeXintercharclass \mycharclassa
\newXeTeXintercharclass \mycharclassA
\newXeTeXintercharclass \mycharclassB
\XeTeXcharclass `\a \mycharclassa
\XeTeXcharclass `\A \mycharclassA
\XeTeXcharclass `\B \mycharclassB
% between "a" and "A":
\XeTeXinterchartoks \mycharclassa \mycharclassA = {[\itshape}
\XeTeXinterchartoks \mycharclassA \mycharclassa = {\upshape]}
% between " " and "B":
\XeTeXinterchartoks 255 \mycharclassB = {\bgroup\color{blue}}
\XeTeXinterchartoks \mycharclassB 255 = {\egroup}
% between "B" and "B":
\XeTeXinterchartoks \mycharclassB \mycharclassB = {.}

\begingroup
\XeTeXinterchartokenstate = 1
aAa A a B aBa BB
\endgroup

\end{document}

Not very pretty, but it proves that it can be done ...

[Tex/LaTex] Multilingual bibliographies with biblatex-chicago babel hyphenation

The Chicago Manual of Style no longer imposes sentence-style capitalization on titles. In response to this change the biblatex-chicago author moved sentence case title formatting from the default authordate style to a new style call authordate-trad. So to obtain an English bibliography with sentence-cased titles load babel and biblatex with the option settings:

\usepackage[german,british]{babel}
\usepackage[authordate-trad,babel=hyphen]{biblatex-chicago}

For a multilingual bibliography incorporating both English and German strings, change the setting babel=hyphen to babel=other. Note that you might need to protect some words in titles from down-casing. For example:

title = {Darwinizing Culture: {The} Status of Memetics as a Science},

Alternatively you can use the subtitle field:

title = {Darwinizing Culture},
subtitle = {The Status of Memetics as a Science},

Also note that sentence case is applied only under the language modules specified in \DeclareCaseLangs. By default:

\DeclareCaseLangs{%
  american,british,canadian,english,australian,newzealand,
  USenglish,UKenglish}

To include german in this list, add the following to your preamble:

\DeclareCaseLangs*{german}
