NTG-context] How to hack the lua files

[Lance Larsen]

I haven't been using the project structure. From your question, I am
inferring that this might help. At present I have treated the files as two
separate documents. I didn't take too much time looking at how to set up the
project structure because it wasn't clear that I needed it. But I can see
how this might impact cross references between documents.

Do you use the project structure? components and such?

NTG-context] How to hack the lua files

[Lance Larsen]

Hans,

Thankyou for your suggestion of using the \usereferences tag to reference
formulas in another document. This is a good solution. However the example
below doesn't give usable results because the references to the external
formula output by test2.tex does not include the chapter number:

test1.tex:
-------------
\starttext
\chapter{Chapter 1}
\placeformula[one] \startformula x = y \stopformula
\placeformula[two] \startformula y = z \stopformula
\chapter{Chapter 2}
\placeformula[three] \startformula z = x \stopformula
\stoptext


test2.tex:
--------------
\usereferences[test1.tex]
\starttext
\in{formula}[test1.tex::one]
\in{formula}[test1.tex::two]
\in{formula}[test1.tex::three]
\stoptext

In the output of test1.tex, the formulas are labeled (1.1), (1.2), and
(2.1). In the output of test2.tex the references are labeled 'formula 1',
'formula 2', and 'formula 1' (i.e. the section number is not included).

Using the \usereferences tag works if I label formulas 'bytext' rather than
by 'bysection' and turn off chapter prefixes in test1.tex using the
following at the start of the document:

\setupformulae[way=bytext,prefixsegments=None]

I would really prefer to maintain numbering by section, but to do this, I
need test2.tex to show external references in the same way as test1.tex (by
including the section number in front of the equation number). Is there a
way to do this at present? If not, labeling formulas 'bytext' will work for
now even if it isn't ideal.

because there are indirect references to for instance 'numberdata' where 
this info sits

see previous mail

btw, if you just want to use references in another tex doc, this will do 
the trick:

\usereferences[somedoc]

\starttext

     \in{formula}[somedoc::a]

     \in{formula}[somedoc::b]

\stoptext
