Hi all,
I just updated my ConTeXt to
system > ConTeXt ver: 2022.07.06 21:42 LMTX fmt: 2022.7.12
int: english/english
yesterday and got a error message in using tex.linebreak(head) as follow:
luatex warning > linebreak: no [ leftinit | rightinit | leftfill |
rigthfill] expected
I can't get any information about them. The head and the list going to
tex.linebreak() like:
the linbebreak routine expects:
<node : nil <= 2371 => 2873 : par vmodepar>
<node : 2371 <= 2873 => 2879 : glue indentskip>
<parinitleftskip>
<parinitrightskip>
<node : 2873 <= 2879 => 2891 : glyph unset>
<node : 2879 <= 2891 => 2897 : glue userskip>
...
<node : 636 <= 3077 => 639 : glyph unset>
<node : 3077 <= 639 => 3089 : kern userkern>

<node : 3089 <= 2334 => 3095 : rule normal>

<node : 642 <= 3107 => nil : glue userskip>
<infinite penalty>
<parfillleftskip>
<parfillrightskip>
My question is:
Which of them is necessary, and
How can I node.new() one and
Where should it go in the list?
the next upload will have a prepare helper
print("=====================================================")
local h = nodes.copylist(head)
tex.preparelinebreak(h)
local n = tex.linebreak(h)
nodes.flushlist(n)
print("=====================================================")
Any hint would be appreciated,
the luametatex par builder is a bit nore advanced than the luatex one as
it offers more features for which it also needs s few more nodes in the
list; it could work without but then its also doesn't honor some
parameters which then would raise questions; so we're more picky instead
(the resulting line boxes are also somewhat different)
