db.connect outside main(): Parameters outside channel

I have my db.connect{} outside of main() for performance reasons but a new requirement states the db parameters must be held in an external file. It’s trivial to do this if the connect is done inside main, but how can I get the parameters into the filter if connect{} is outside main? Thank you in advance.

Just a matter of writing a function and calling it in the body of the main lua module for the translator instance.

In reality when you write:

local DB = db.connect{...}

It’s actually doing a function call to that function.

Sometimes for debugging if I can be bothered I will write a function which uses a boolean variable outside of main like this:

local Initialized = false

function Init()
   if not Initialized then 
       -- Do initialization       
       Initialized = true;
   end
end

function main(Data)
   Init();
end

The nice thing about this is that you get annotations and intellisense so it makes it easier to write the code.
