EPICS Lua global variables

[James King - UKRI STFC via Tech-talk <tech-talk@aps.anl.gov>]

Hello Tech-talk,

 

I have been working on getting an IOC booting with Lua. Lua guidelines suggest the use of local variables rather than global. I notice that Macros are available as global variables and we cannot use local variables as they drop out of scope due to the nature of Lua interactive mode scopes.

 

Does anyone have any experience of using local variables in Lua IOC boot scripts? Or any information as to how global variables are contained in the Lua shell?

 

Many thanks for any replies and help given.

 

Kind regards,

James
