Hi list, I want to simulate \hss in lua end in ConTeXt/luametatex environment. For example, ```ConTeXt a{\raise 1.5ex\hbox to 0pt{\hss b}}c ``` should get 'b' on top of 'a', as follows: ```pdf b ac ``` and in lua, I see a <glue userskip> before "b" node, width width:0, stretch:65536, shrink:65536, stretchorder:2, shrinkorder:2 And in lua, I do as follows(part of my app seen in attachment): ```lua local hss = node_new(glue_id) hss.stretch = 65536 hss.stretchorder = 2 hss.shrink = 65536 hss.shrinkorder = 2 hss.width = 0 list,_ = node_insertbefore(list, list, hss) -- b is in the list -- I got a <glue userskip> with width:0, stretch:65536, shrink:65536, stretchorder:2, shrinkorder:2 local box = node_new(hlist_id, "box") box.head = list box.width = 0 box.shift = -tex_sp("1ex") -- I got <hlist box> width:0 height:0 deep:0 shift: -503424 head, current = node_insertbefore(head,current, box) -- current is 'c' node ``` And got 'b' on top of 'c' in pdf as follows: ```pdf b ac ``` How can I get 'b' on top of 'a' as \hss do? ___________________________________________________________________________________ If your question is of interest to others as well, please add an entry to the Wiki! maillist : ntg-context@ntg.nl / https://www.ntg.nl/mailman/listinfo/ntg-context webpage : https://www.pragma-ade.nl / http://context.aanhet.net archive : https://bitbucket.org/phg/context-mirror/commits/ wiki : https://contextgarden.net ___________________________________________________________________________________
