Another difference in mkii and mkiv handling of sometxt. If there is a

\starttext

draw \sometxt{A very
long string} ;
\stopMPcode
\stoptext
I vaguely understand why this is happening, but I do not know if it can be
corrected.
in mkii we obey lines because it gives better tracing etc etc given that
we use external files; this will work:
draw \sometxt{A very %
long string} ;
Ah, thanks.
indeed mkiv is different but let's consider it an improvement; i don't
want to waste time on mkii fixes that are not that important
I understand that. We need to document all these differences between mkii
and mkiv with regards to mp interaction for those who want to write code
that works in both. Mojca, any plans to update your MyWay?
If you want to do changes, just go ahead (you might be more
competitive to describe them).
Otherwise: I'm not sure what all the differences are.
1.) withcolor doesn't work
2.) \startTeXtexsts cannot be used
3.) the example above fails in mkii
What else?

In MKIV certain commands inside \sometxt should be unexpandable. I do not
really understand which ones, but I occasionally get errors which can be
fixed by making the command unexpandable.

Hi,
I cannot understand why mkii and mkiv give different output in the attached
example modified from Thomas's presentation module. The output of MKII is
correct. In MKIV, the first picture (Left) is not correct, and I cannot
understand why is this the case.
I am using the latest minimals and the latest svn luatex.
MKIV is very strict about the spaces. I had
Left := \sometxt[taspresent:sometxt:left] {\folio} ysized 6cm;
Right := \sometxt[taspresent:sometxt:right]{\folio} ysized 6cm;
(notice the space before \folio in Left). MKIV does not like that. If I
remove the space, everything is fine.

It seems we can fix that by redefining the definition of \sometxt.

Sorry, make that \definetextext. The macro \sometxt has to be
expandable, which limits the amount of tricks we can do with it.
This patch works:
\def\definetextext[#1]#2%
{\setvalue{@@st@@[#1]}{#2}%
\setvalue{@@st@@[#1] }{#2}% added
}
Best wishes,
Taco

Ha, I can now claim that I figured out one TeX problem faster than
you :-) Of course, you also figured out a solution :-D
