Re: How to hack the lua files

Re: How to hack the lua files

[Lance Larsen]

luigi,

When I started exploring how to map equation references (eq:name) to
equation numbers (4.2), I noticed that the 'tuc' file included the equation
reference (eq:name), but I was not able to identify anywhere where it
indicates the actual equation label specified in the document. Below is an
example of the tuc output. 'eq:DVOL_RVI_17' is equation (4.28) in the
document:

{
  ["metadata"]=142,
  ["numberdata"]=237,
  ["prefixdata"]=11,
  ["references"]={
   ["block"]="bodypart",
   ["internal"]=122,
   ["realpage"]=47,
   ["reference"]="eq:DVOL_RVI_17",
   ["section"]=79,
  },
 }

There is nowhere in the tuc file that contains 4 and 28 near each other. I
checked this for other equations as well and concluded that the tuc file
does not contain the actual equation numbers that are used.

If I am missing something or you have any other suggestions that might help
me to extract this info, I would sure appreciate the help.

-Lance

P.S. Thanks for the tip on using 'context --make' to rebuild the files. I
figured this out by guesswork before I got your response, but I have
appreciated how helpful many of you have been on this list.

\usemodule[newmath]

\setupformulas[way=bytext,prefix=no]
\setupsubformulas[conversion=romannumerals]

\starttext
\placenamedformula[eq:TEST]{Der einfache Test}
\startformula
c^2 = a^2 + b^2.
\stopformula

\stoptext

and look into the tuc file (it's a lua file)

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

Hans,

Referencing equations from another context document is what I am trying to
do. It think the \usereferences tag that you noted in the ideal solution for
my case. Thanks again for the help.
