title	Connect it the component we want to test with - done!

See Linking components if you need a refresher.

title	Add some custom logging

Let’s add some Custom Logging

Just added lines 7 and 11 to the script:

Code Block

language	lua

function main(Data)
   local F = component.fields().InputFile
   trace(F)
   local Content = FILread(F)
   local List = Content:split("\n")
   trace(#List)  
   iguana.logInfo("#start About to queue "..#List.." messages");
   for i=1, #List do
      queue.push{data=List[i]}
   end
   iguana.logInfo("#end Finished queueing "..#List.." messages");
end

See Concatenating strings for more on the “..“ notation to bring join strings together.

title	And some custom status

See Custom Status

Code Block

language	lua

require "FIL.FILreadWrite"

function Status(N, Total)
   component.setStatus{data="Sending "..N.." of "..Total}  
end

function StatusDone(Total)
   component.setStatus{data="Completed sending "..Total.." messages."}
end

function main(Data)
   local F = component.fields().InputFile
   trace(F)
   local Content = FILread(F)
   local List = Content:split("\n")
   trace(#List)  
   iguana.logInfo("#start About to queue "..#List.." messages");
   for i=1, #List do
      Status(i, #List)
      queue.push{data=List[i]}
   end
   StatusDone(#List)
   iguana.logInfo("#end Finished queueing "..#List.." messages");
end

title	Like a copy of the code?

The repository is here:

title	Couple of videos showing the component in action

This shows using the component and the internals:

internals.mp4

And this one shows using the logs from the component:

logs.mp4

And now we have a simple tool that makes it easy to test our HL7 interfaces. But more importantly this exercise puts together a set of little concepts that once you grasp you can solve not only simple problems, but you can build up the skills to be able solve complex ones as well. There are no bottlenecks you cannot remove.
