Hi Hans,
Using node.setglue in LuaMetaTeX sets all of the glue components to zero.
This example:
\startluacode local stretch_order = "stretch_order" local shrink_order = "shrink_order" if status.luatex_engine == "luametatex" then stretch_order = "stretchorder" shrink_order ="shrinkorder" end
local glue = node.new "glue" print(node.getglue(glue)) node.setglue(glue, 1, 2, 3, 4, 5) print(node.getglue(glue)) glue.width = 1 glue.stretch = 2 glue.shrink = 3 glue[stretch_order] = 4 glue[shrink_order] = 5 print(node.getglue(glue)) node.setglue(glue, 1, 2, 3, 4, 5) print(node.getglue(glue)) \stopluacode
produces this output in MkIV:
0 0 0 0 0 1 2 3 4 5 1 2 3 4 5 1 2 3 4 5
but this output in MkXL:
0 0 0 0 0 0 0 0 0 0 1 2 3 4 5 0 0 0 0 0 it is unrelated to luametatex in the sense that it doesn't have that setter, so we emulate it in node-cmp.lmt:
function node.setglue (n,...) return setglue (todirect(n),...) end but even then you won't get the '5' as bad values are intercepted ... i'll also add some extra checks to those field setters 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 -----------------------------------------------------------------
