Re: [NTG-context] Problem with MkIV and TikZ picture remembering
Is that really an mkiv issue? If I understood well tikz has its own way
of keeping track of positions independent of context.
Normally yes.
But there is TikZ’ “remember picture” mode. You can produce several
independent TikZ pictures on a ConTeXt/LaTeX/plain text page. TikZ tells
ConTeXt (or LaTeX or plain TeX) to give back the coordinates of those
pictures on the page after the page has been typeset. TikZ can then draw
interconnections between those images which are rendered in an extra run.
In my example the rounded rectangles with the words inside are TikZ
images which are put inline into the ConteXt text by the command
\tikz[baseline] \node[form of node, draw, anchor=text] {text content}
When I use
\tikz[baseline, remember picture] …
instead I activate the mode explained above and the arrows can be drawn
according to the “remembered” coordinates after ConTeXt’s first
typesetting run.
According to Wolfgang Schuster in the first reply in this thread when
using ConTeXt mkiv – other than mkii – file the coordinates given back
after the first typesetting run look strange in TikZ’ auxiliary so there
seems to be a mistake somnewhere between ConTeXt and TikZ in this regard.

Tikz uses the pdftex commands \pdfsavepos, \pdflastxpos and \pdflastypos to
save the position
of the graphics on the page. ConTeXt isn’t involved in this process which
provides its own
interface for this mechanism but Tikz doesn’t use it.
In my example the rounded rectangles with the words inside are TikZ images

The problem is the \write command which differs in MkII and MkIV and Tikz
way to prevent the expansion of a command which is written to the auxiliary
file.
The following example demonstrates the difference between MkII and MkIV.
In MkII the \noexpand prevents the expansion of \dummytext when writes
content is written to the external file but in MkIV \write is redefined and this
doesn’t work anymore.
begin example
\newwrite\testwrite
\starttext
\immediate\openout\testwrite=\jobname-dummytext.tmp
\def\dummytext{First sample text.}
\immediate\write\testwrite{\noexpand\dummytext}
\def\dummytext{Second sample text.}
\immediate\write\testwrite{\noexpand\dummytext}
\immediate\closeout\testwrite
\stoptext
end example

[NTG-context] Update text variables inside metapost
Why the metapost not updated the value of text variables that are generated
inside luacode environment?
In the code below, If I have \startitemize[columns,two] then metapost draw:

2. and four \Bolha[size=4cm]{text1}{text2}{text3}, but text1, text2 and
text3 is not updated in every call;
If I omit the itemize environment or with \startitemize metapost only draw:
1. the first call of Bolha that is: \Bolha[size=6cm]{text1}{text2}{text3}

In this case I would like ConTeXt to break the page at

Hi Massi,
how about before={\blank[2*line]\page[bigpreference]}?
As Wolgang noted before, a minimal sample is essential to be able to

You can use the \testpage command where you can set how many

\setuphead[LetterTitle][before={\testpage[8]\blank[2*line]}]
If this doesn’t help you should make a *working* minimal example.

Re: [NTG-context] Problem with MkIV and TikZ picture remembering
Thank you very much Hans and Aditya for your efforts and sorry for only
replying now — momentarily I am writing a paper (of course typeset with
ConTeXt :-) ) that has to get finished.
For now I have dropped the idea of using that certain type of
illustration in the paper as your METAPOST examples are working, but I
had forgotten to say that I need effectively two arrows from one part of
a sentence two two others (I am trying to illustrate a linguistic
ambiguity problem) and I did not manage to get that working starting
from your examples. Then I need a shape other than a tight frame to
surround the words, TikZ’ rounded rectangles were too nice for that. In
the moment I don’t have the time to dive deeper into METAPOST which
seems to be a mighty beast from what I see in the Metafun manual, but in
future I shurely will.
The nice thing about TikZ are that you can use the self explaining
commands rather intuitively (at least having some experience in Lilypond
and now ConTeXt), that there are many different building blocks
predefined that you can use and that there are hundreds of examples in
the internet that you can use as starting point. So I managed to get
some things working after a self-tought one day crash course –
Metapost’s learnig curve seems to be a lot steeper to me. It is really a
pity that ConTeXt mkiv does not save the node coordinates correctly as
Wolfgang found out.
Greetings Jörg
