Re: [NTG-context] linebreak error: no leftinit or rightinit or leftfill or rigthfill expected

[黄复雄 via ntg-context]

Thanks， Hans.
My module works again now, with the help of tex.preparelinebreak().

For potential readers:
tex.preparelinebreak(list)  modifyed my list for tex.linebreak(list) to:

 # by user in advance, necessary


   # by user in advance, necessary
...
 # The last glue here, in the end of the list, is
removed

 # as same as parfillrightskip

Thanks, Hans

I modified my list to:

   2873 : par vmodepar>
   3113 : glue indentskip>
   3119 : glue parinitleftskip>
   2879 : glue parinitrightskip>
   2891 : glyph unset>
...
639 : glyph unset>
   3089 : kern userkern>
   2334 : glue userskip>
   3095 : rule normal>
   3101 : glue spaceskip>
642 : glue spaceskip>
   3107 : penalty userpenalty>
645 : glue userskip>
   3125 : penalty userpenalty>
   3131 : glue parfillleftskip>
nil : glue parfillskip>

but the error is the same, so I'll wait the  tex.preparelinebreak(), and
observe it's work for more details.

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:


   2873 : par vmodepar>
   2879 : glue indentskip>






   2891 : glyph unset>
   2897 : glue userskip>
...
    639 : glyph unset>
   3089 : kern userkern>
   2334 : glue userskip>
   3095 : rule normal>
   3101 : glue spaceskip>
    642 : glue spaceskip>
   3107 : penalty userpenalty>
    nil : glue userskip>








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)

Where do you intercept the list?
