[NTG-context] parbuilder in lua

Hi Hans, Can you please try the code below? I found three issues with it: 1. node-ltp.lua is not completely ready for nuts mode, e.g. line 3148: elseif order == 0 and hlist.list and last_badness > tex.hbadness then where ‘hlist.list' should be 'getfield(hlist, "list”)’ 2. with tracing on, I always get: Lua linebreak_filter failed, reverting to default on line 1 which makes me nervous. Does that mean it works ok without tracing, or does it just not report that it does not work? 3. with tracing on, there is a double-free of a glyph node (this could be specific to tufte) TIA, Taco Code: \tracingparagraphs=1 \tracingonline=1 \starttext \startparbuilder[basic] \input tufte \stopparbuilder \stoptext
