This is quite a technically involved question. Of which the essence is how XeLaTeX handles page-breaking.

I need to produce a bilingual book. With one language on the left hand side page and another language covering the same text on the right hand side page.

There are a few points to bear in mind:

  • The book being produced is the Holy Bible, so it is a very large text, therefore as much of the work as possible should be automated..
  • It needs to end the same verse for both languages for every set of pages.
  • All the packages included in the MWE below are actually used by other features in the final product.

So bearing this all in mind, the question is; Does XeLaTeX have the ability to find out how much of my text have been used on the page. Or which is the last Section / Subsection used on the page. So that it can be used for the second language to produce the same content on that page.

MWE:

Do you know the parallel package? –  Stephan Lehmke Dec 10 '12 at 13:49

A bit off-topic, but are you sure you want Times New Roman? For me, it sounds almost like a blasphemy; the Holy Bible does deserve a beautiful font, not one of the ugliest ones... –  mbork Dec 10 '12 at 17:53

ledpar is another good option, though it is geared more towards critical editions with facing page translations. –  jon Dec 10 '12 at 20:02

@McGafter -- oh, right! I forgot about newer eledpar! You should probably consult the ledpar and ledmac manuals for basic set-up stuff. But I haven't had occasion to use newer versions yet. If the existing answer does what you need, I won't bother providing an eledpar example. But note that you should use pdfcolparallel in place of the parallel package, as the former fixes bugs of the latter and provides colour support (which may not be necessary in your case). As for your fonts, you could use (IMHO) a freer and yet nicer font, like Linux Libertine, or the TeX-Gyre fonts. –  jon Dec 11 '12 at 17:12

@McGafter -- I posted an example. There seem to be a few problems with the current versions of eled*, but I think there are workarounds for now. –  jon Dec 12 '12 at 16:40

Ok, it turns out there are a few problems with the versions of eledpar and eledmac, which I just downloaded from CTAN. The first is that there is a serious bug if you use the memoir class, which I didn't have time to look into. Update: This has been addressed on eledmac's github page, but it has not made it to CTAN yet.

That said, however, an eledpar way of going about this:

\documentclass[12pt]{article}

\usepackage[utf8]{inputenc}%
\usepackage[T1]{fontenc}%
\usepackage[fulloldstylenums,largesmallcaps]{kpfonts}%

\usepackage{eledmac, eledpar,lipsum}

\numberlinefalse% turn off lineation commands (from eledmac)

\usepackage[spanish,english]{babel}

It may be wiser to create your own Spanish and English environments for each chunk of text, but I left them as is to illustrate the mandatory parts of each 'side'. If you prefer parallel columns, then change

\begin{pages} 
... 
\Pages 
\end{pages}

to:

\begin{pairs}
...
\Columns
\end{pairs}

Even though Stephan Lehmke has a good solution below it looks like this answer fits my needs better, so I'll accept it instead of the other one. –  McGafter Dec 13 '12 at 10:05
    
@McGafter -- Glad it works for you! –  jon Dec 13 '12 at 14:08
    
I meant to say Peter Jansson, not Stephan Lehmke... oops. –  McGafter Dec 13 '12 at 15:48

Although Stephan Lehmke has already suggested the parallel package, I thought I might add to that comment. I have used the parallel package for bilingual course descriptions. It works very well and provides me with an excellent way to provide domestic and foreign students with identical information. From what i have read and experienced the package has some drawbacks. The most disturbing is that the list environments may totally mess up things. I found that I could mock up list environments using the hanging package. It does not seem that you will need lists very much in your case but be aware that the parallel package is not perfect in that sense and that you may need to find alternative solutions to some typesetting features provided by LaTeX in general. Another detail is that paragraphs are indented so you need to add a \noindent for the first paragraph if that is what you need. Here is an MWE:

\documentclass{article}
\usepackage{parallel,hanging}

\begin{document}

\begin{Parallel}[v]{.47\textwidth}{.47\textwidth}
   \ParallelLText{\noindent Some introductory text in language 1, not to be indented

   \begin{hangparas}{4mm}{1}
      --- Some text in language 1

      --- Some more text in language 1

   \end{hangparas}

   }
   \ParallelRText{\noindent Some introductory text in language 2, not to be indented

   \begin{hangparas}{4mm}{1}
      --- some text in language 2

      --- some more text in language 2
   \end{hangparas}

   }
\end{Parallel}

\end{document}
