C://Users/rik/Desktop/xxx.tex:

(It always points to line 4 of the file, no matter the file.) When the 
halt is answered with a CR, the processing runs to completion with no 
apparent errors.


When the first line is removed, or the state set to stop, compilation 
completes normally.


When the content of the setup (the two-line \setlayer) is moved out of 
the setup, compilation completes normally (without regard to tagging).

there are other items in the layer that cannot be properly handled until 
after \starttext processing.

fixed in next beta (no tagging of backgrounds)

Re: [NTG-context] Lua problem with tagging or setups

No, cow.pdf is in the default location and is found with no problem when 
tagging is off or the setlayer is moved out of the setup. The Lua error 
does not occur with most commands, but does occur with external figures.

[NTG-context] Lua problem with tagging or setups

2017-10-09 Thread Rik Kabel 

Consider the following almost-minimal example:

   \setuptagging    [state=start]
   \setuppapersize  [A6]
   \setupexternalfigures[location=default]
   \definemakeup    [cover4][page=left,doublesided=no]
   \definelayer [isbn][width=\pagewidth,height=\pageheight]
   \define  \Title {A Primer on Omphaloskepsis}
   \startsetups [placeisbn]
  \setlayer [isbn][preset=rightbottom,hoffset=5mm,voffset=5mm]
  {\externalfigure[cow.pdf][width=3cm]}
   \stopsetups
   \starttext
  \setupbackgrounds  [page][setups=placeisbn,background=isbn]
  \startmakeup   [cover4]
  \scale [width=\textwidth] {\red \Title}
  \stopmakeup
   \stoptext

For me  (Win64, current standalone beta), compilation halts with:
