Hi Hans,
The new tex.preparelinebreak is great (thanks again), but I can't seem to figure out how to manipulate the parfillskip nodes that it adds.
MWE:
\newbox\testbox
\startluacode function test(head) if head.id ~= node.id "par" then return head end
new_head = node.copylist(head) tex.preparelinebreak(new_head)
local parfillskip = node.tail(new_head) inspect(parfillskip) -- Confirm that this really is a parfillskip parfillskip.stretchorder = 0 parfillskip.stretch = 0
local broken = tex.linebreak(new_head) tex.setbox("global", "testbox", broken)
return head end \stopluacode
\starttext {\dorecurse{209}{Hello }\par}\page
{\parfillskip=0pt\dorecurse{209}{Hello }\par}\page
{\ctxlua{nodes.tasks.appendaction("processors", "after", "test")} \dorecurse{209}{Hello }\par}\page
\box\testbox \stoptext
I would expect that pages 1 and 3 would be identical, and that pages 2 and 4 would be identical. However, page 4 is the same as pages 1 and 3, which isn't what I'd expect. I can do a similar idea in LuaTeX/MkIV and get the expected results, so I'm not too sure what I'm doing wrong here. I'm probably just missing something obvious, but I'm not too sure what. Any ideas? looks like i don't update something, i'll fix it (probably bin later today)
btw, you can do this: local h, t, pil, pir, pfl, pfr = tex.preparelinebreak(new_head) inspect(pfr) pfr.stretchorder = 0 pfr.stretch = 0 as well as use tex.show(broken) to see the result 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 -----------------------------------------------------------------
