(again) issues with streams

(again) issues with streams

[Pablo Rodríguez]

Hi there,

playing with an example posted by Wolfgang to the list, I'm trying to
generate a bilingual poetry edition (original and facing translation).

If anyone could help, I'd really appreciate (this is the second time I
post the message to the list
http://www.ntg.nl/pipermail/ntg-context/2011/064184.html).

This is a minimal sample:

	\enabletrackers[streams.flushing]
	\def\itit#1{{\language[it]\em#1}}
	\starttext
	\completecontent
	
	\startoutputstream[agr]
	
	\dorecurse{4}{\chapter{Knuth}\input knuth\par}
	
	\enableoutputstream[es]
	
	\dorecurse{4}{\chapter{Ward}\input ward\par \input tufte\par}
	
	\disableoutputstream
	\stopoutputstream
	\synchronizestreams[agr,es]
	\page \flushoutputstream[agr]
	\page \flushoutputstream[es]
	\stoptext

My first question is how can I make that ConTeXt synchronizes
automatically titles and paragraphs. I mean, I want to type the original
first and the translation after the original and that ConTeXt typesets
everything right (original with facing translation).

My second question is how can I do that numbering on both sides is
really independent. I mean that chapter and similar titles have the same
number that its facing translations (and the same for footnotes).

My third question is how can I number lines there, since I get the
following error when using \starlinenumbering ... \stoplinenumbering
(this is all Greek to me):

!LuaTeX error: There should have been a lua <node> here, not an object
with type nil!
 ==> Fatal error occurred, no output PDF file produced!
Compilation failed.
mtx-context     | fatal error: return code: 70

Thanks for your help,


Pablo
