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
