Re: [NTG-context] Moving horizontally a whole ensemble of layers in the same run?

Hi Hans,

By luacode we can calculate how much the centring movement should be, because we
know "\textwidth", but we cannot save the calculated centring value in the
context
program for another run. Saving the luacode values of hundred of pages in
flattened
lua tables would be possible, but rather awkward; the problem of relating pages
to
tables would arise, especially when pages are taken out or additional pages are
inserted.
Do you know a way to settle the centring in the same context run in which the
layers
are placed? Could "\flushlayer" perform it somehow?
you need to make a MWE to show what you mean
normally
\hbox to {\hss\hss}
is good enough for centering

Best regards: OK

\setupsynctex[stat=start]
\setupsynctex[state=start] % if this is removed then everything is fine…
\setupquotation[style=italic,left={«~},right={~»}]

\dorecurse{4}{\item This item \quotation{is shown correcly\dots}

\stopitemize

took me a while to figure out that it is actually an engine issue
(obscured in luatex but exposed in luametatex)
fixed in next beta
