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
