INIT call

One of the design challenges with Iguana X is how to start components which do not have a component feeding into them.

From 10.1.86 our design solution for this that Iguana X will call the main(Data) function with Data set equal to “INIT”.

This is quite a substantial change from how we did this prior to this. Our components which needed to be boot-strapped had a pattern like this:

if not iguana.isTest() then 
   -- do some initialization
end

This seemed quite difficult to remember. It’s nicer to be able to have initialization as a specific message and then be able to see it in the logs for a component.

For customers who have been evaluating IguanaX prior to this change it will be necessary to update components to handle this change. This is the new pattern:

function main(Data)
   if Data == "INIT" then
      -- do some initialization
      return
   end
end
