Hello, is there a Lua variable/namespace which is stored automatically between Ctx "*first" and following runs? I thought 'userdata' is intended for this, but it seems it's not; I'd like to achieve something like: ---- \startluacode if tex.modes["*first"] then userdata.LPr = "Something" -- Is there a variable which is shared between Ctx runs? else assert(userdata.LPr == "Something") end \stopluacode ---- Of course, I can store the table via serialization functions to an extra file, but I thought there is already a variable/mechanism for this (e.g. using .tua/.tuc file) ... is it?
