Fundamental change in index mechanism ?

Fundamental change in index mechanism ?

[Steffen Wolfrum]

Hi,

because of a second edition I had to typeset a project from august  
2006 a second time (with very, very little text changes).

Then, I experienced that the register had changed (a simple \index 
[keyword] and \placeregister[index]).
And with a closer look I saw that in the first edition the index  
entries also get listed in the index register when appearing also in  
the TOC content! Now, it was impossible for me to reproduce this: The  
first listed entries now came from the beginning of the actual text.

Is this a know bug? (Is there already a fix for it?)

IMO, the current behaviour (as I understand it) is a bugfix for the
known bug of pointlessly indexing a lookup table.

Ask yourself: why would anyone want to be pointed to the table of
contents from within the register?

if y ou provide a sample that shows the problem .. all things can be fixed since i have no intention to break downward compatibility.  


\placeregister[index] \page

\placelist[section] \page

\starttext

\section{oeps \index{oeps}} \input tufte

\stoptext

works ok here

A minimal example is again not so easily written (as I don't know  
where the problem is).

But if you don't mind I could send you the actual files privately.

Sure, you are absolutely right (it was not my decision to typeset the  
first edition the way it actually was set).

As far as I could see – apart from temporary workarounds (I remember  
troubles with columns) – all old ConTeXt files generate the same  
output when typeset with a current ConTeXt version.

So I was just wondering that my 3 month old file generates a  
different output today.
