How to load a lua file into a named lua instance

How to load a lua file into a named lua instance

Hi all,

I have a module with lots of lua code, and I'd like to move most of the lua
code to a separate file, say t-module.lua. I have written all of the lua
code using \modulecode and \startmodulecode ... \stopmodulecode. But, when I
move the lua code to t-module.lua and load it with dofile, it seems to load
in the global instance instead of the third party module instance. Is there
any method to load an external lua file in a named instance?

Thanks,

Kevin

\registerctxluafile{t-module}{}

Hi Hans,

I started reading at \registerctxluafile in luat-cod.mkiv, but it wasn't
quite what I was looking for. But, I then stumbled on \definenamedlua in
luat-ini.mkiv. There, I learned of the function 'protect' in luat-ini.lua.
So, adding the line

protect("moduledata")

at the top of t-module.lua and then loading this file with 'dofile
(global.kpse.find_file ("t-module.lua", "tex"))' loads all my definitions
into the "moduledata" environment, so that I can directly address these
definitions in other TeX files within \modulecode{} or \startmodulecode ...
\stopmodulecode.
