Hi Hans,
When running in \normalizelinemode=0, the \parinitleftskip and \parinitrightskip nodes are either nonexistant or invisible from Lua, causing tex.linebreak to not work correctly.
This sample file:
\enabledirectives[system.callbacks.permitoverloads]
\normalizelinemode=0
\directlua{ callback.register("pre_linebreak_filter", function(head) tex.preparelinebreak(head) local list, info = tex.linebreak(head) print(info)
return head end) }
\starttext \input knuth \stoptext
Produces this output:
luatex warning > linebreak: list seems already prepared luatex warning > linebreak: [ leftinit | rightinit | leftfill | rigthfill ] expected nil i'll bypass that warnign when the mode is zero
btw, you need to work with a copy of the list Hans ----------------------------------------------------------------- Hans Hagen | PRAGMA ADE Ridderstraat 27 | 8061 GH Hasselt | The Netherlands tel: 038 477 53 69 | www.pragma-ade.nl | www.pragma-pod.nl -----------------------------------------------------------------
