frames for left/right pages

frames for left/right pages

[Thomas A. Schmitz]

Hi,

I have a wish list for independent frames and would like to know if this 
is possible in ConTeXt:

1. left and right pages in a doublesided document have frames with 
independent text flow, i.e. the text from p. 2 continues on p. 4, from 
p. 3 on p. 5, etc. The frames are regular frames and can have 
backgrounds, borders, etc.

2. After a couple of pages, these frames end. Below them, the text flows 
normally, i.e. begins below frame on p. 6 and continues below frame on p. 7.

3. Since I want to take my data from xml, the content of the frames will 
be taken from buffers.

So this would give, in pseudo-code:

\starttext

\startleftrightbuffers
\leftframe{\getbuffer[left]}

\rightframe{\getbuffer[right}
\stopleftrightbuffers

Here, the normal text begins, it will flow below the frames...

\stoptext

Is this possible? How would I code that?

Thanks for any pointers

Thomas

Are you looking for streams, the mechanism Hans added for you years ago?

I'll have to look into Hans's rewrite of streams. As far as I remember, 
they were much more complex (offering synchronization etc.). Also, 
streams seem to be bound to full pages and don't offer backgrounds. So I 
think I'm looking for something simpler, yet more versatile.
