for the brave

[Hans Hagen <pragma@wxs.nl>]

Hi,

I uploaded beta zip with a prelude to the new structure related code. I 
hope that I didn't forget files.

   context --make xp

will generate the experimental format (you really need a luatools 
--generate because there are many new files).

With

   context --interface=xp yourfile

will use that format. Eventually the xp format will go away but this is 
a nice intermediate step for those who are willing to help debugging the 
code.

Those who look into the source ... it all happens in strc-*.tex|lua and 
when you look in the tua/tuc file you see what is carried around (this 
will be optimized). Much code still needs a rewrite.

The format file is slightly smaller and less hash space is used, in 
spite of more functionality. This is a side effect of a more dynamic 
inheritance model (slower, but not so much an issue noaways and 
compensated by speedups in other areas like one time multipass data 
reading).

For xml users: although somewhat experimental, we now have roundtrip xml 
  in lists (and some other constructs, more to come).

\setuphead[chapter][expansion=xml]

This only works for mkiv xml, as we also keep track of the document root 
in order to apply the right setups.

For Aditya: numbering of math is redone and soon we have to split up 
strc-mat into pieces (when we start doing unicode math) but you can 
already have a look at it.

Don't worry too much if your documents crash. I simply cannot test 
everything so it might be a good opportunity for volunteers to help 
documenting behaviour and making tests.

The main incompatibilities are in the numbering: we now use sets for 
numbering, seperators, converters etc as well as processors for specific 
layout of these thingies. This info is carried around so that 
intermediate style changes are reflected in tables of contents and 
references (of course they can be overloaded). It's the price we pay fro 
more flexibility.

Hans
