Storing Lua values between Ctx "*first* and next runs

Storing Lua values between Ctx "*first* and next runs

[Procházka Lukáš Ing.]

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?

Best regards,

Lukas
