AFAIU, no. I have not checked if runs=11 on top of the file is read.

No, runs=11 is not read. But anyway, I would need something like
\maxruns{11}, because I would like to put it in a module, that needs a
lot of runs to converge (vertical spacing adjustment to get a letter where
the last page is filled at least to 30%).

everystoptext is more tricky and cannot be handled in the nested case;
starttext is less tricky ; both are only expanded once

The layer kopf is being set before the tui file is read. So, the value
of \nofPoints is still 0. You need to set this layer after the
utility file is read by appending the code to \everyafterutilityread
or to \everystarttext (which happens after reading utility file).

Hello,
i just playing a little bit with macros.
For adding points to a total sum i use this macros

this is working well but my problem is I want to use \summeP on the
first page to show the total amount of points for the whole exam.
I know that this needs a second run of texexec, but I don't know how to
store the value at the end of the file and reread this stored value in a
second run the get the right value.
Here is how to do the second run. I also use ConTeXt macros
(\makecounter etc) instead of plain TeX. Be careful of spurious
linebreaks.

Hmm... I would have guessed that you will keep on getting infinite
runs, but apparently texexec decides that two are enough. I need to
look deeper to see if this is the intended behaviour. I would call it
a bug, since there can be cases which need more than two runs to
converge.

how about
\savecurrentvalue\SomeVar{someval}
I was just copying the way it is done with other macros \lastpage,
etc. I will look at \savecurrentvalue also. However, something seems
to be wrong in tex.rb
Change
def processfile
while ! stoprunning (texruns nofruns) ok do
end
...
end
to
def processfile
while ! stoprunning (texruns nofruns) ok do
report(stoprunning #{stoprunning})
report(texruns=#{texruns}, nofruns=#{nofruns})
report(ok=#{ok})
report(while=#{! stoprunning (texruns nofruns) ok})
end
...
end
so that we can see what takes us out of the while loop.
Take Petar's test file and run it through texexec. I get
TeXExec | stoprunning true
TeXExec | texruns=2, nofruns=8
TeXExec | ok=counter.tex
TeXExec | while=counter.tex
Notice that ok=\jobname. Shouldn't ok be a boolean. And the condition
for while is a string rather than a boolean. I am not too sure on what
ruby does for non boolean conditionals, but the present implementation
can break (under some crazy conditions, maybe). How about if in
def runtexutil(...)
there is a return ok in the end, for example
begin
logger = Logger.new('TeXUtil')
if tu = TeXUtil::Converter.new(logger) and tu.loaded(fname) then
ok = tu.processed tu.saved tu.finalized
end
rescue
Kpse.runscript('texutil',fname,options)
else
return ok #- added.
end
Back to Peter's question, I gave a wrong explaination earlier. texexec
just checks if the tui file has changed. If the file did not change
from the last run, then it stops processing. So with
\savetwopassdata{test}{1}{2}
you will get two runs the first time you process the file, and a
single run if you reprocess the file. By default, the maximum number
of runs that you can have is 8, but you can change this by passing
--runs= to texexec
