line break after \item, but not \stopitem

line break after \item, but not \stopitem

[Damien Thiriet]

Hi list,

I am designing a presentation for my pupils (some loooong exercices to
learn LibreOfficeDraw by doing). To be sure that they don't misview any
question, I decided to force a pagebreak after each first level item.

A question on TSE gave me the proper key to \setupitemize, but I am
facing an issue I didn't expect.

Given this MWE

\setuppapersize[S6]
\setupitemize[1][inbetween={\page}]

\starttext
\startitemize[n]
\startitem \input knuth 
\stopitem
\startitem \input ward 
   \startitemize[a]
      \startitem first point \stopitem
      \startitem second point \stopitem
      \stopitem    
   \stopitemize
\stoptext

I expected a page break after each 1 level \stopitem, that is after
knuth's text and "second point". However the text is breaking before
first point, that is at the beginning of level 2 startitemize, which is
AFAIK semantically part of a level 1 item.
Do you have any idea to force page break *after* "second point" and not
*before* "first point" ?

Thanks,

Damien Thiriet

inbetween is actually meant for spacing so there is logic deep down that 
put is between seccessive items depending on curcumstances .... hard to 
beat heuristics

you can do this:

\setuppapersize[S6]
\setupitemize[1][before={\page}]

\starttext

\startitemize[n]
     \startitem \input knuth \stopitem
\stopitemize

\startitemize[continue]
\startitem \input ward
    \startitemize[a]
       \startitem first point \stopitem
       \startitem second point \stopitem
       \stopitem
    \stopitemize
\stopitem
\stopitemize

\stoptext

Unfortunately, I have a huge amount of level
1 items, only 10% of them enclosing some level-2 itemization. I bet it 
would be easier to insert \page with a perl script after each first 
\stopitem than embedding those 90% items within an itemization (as far
as I understand). That's what I did when I converted my beamer
presentation into conTeXt ones. In this case however,   the code would be 
far less readable, since those \page will be only for screen mode.

Is there any key I could use to introduce page breaks after each level 1
\stopitem ? 

Best regards,

Damien Thiriet

Whether the second level \startitemize uses before or inbetween depends 
on the \c_strc_itemgroups_spacing_mode value which has no option to 
change it on the user level.

The simpler solution for the original problem is to use a enumeration 
for the first level items.
