When writing Translator scripts, a useful operation to have on hand is the ability to resubmit a logged message to an Iguana channel. This module uses the same web service hook that Iguana’s own user interface uses to resubmit a message.

To use the resubmit module effectively, you’ll need to know the unique reference number for the message (or refmsgid). You can get this information by querying the logs.  To learn more, see Obtaining a Direct Link to a Logged Message.

How to use resubmit.lua:

• Add it to your shared modules in any Translator project
• Add local resubmit = require 'resubmit' at the top of your script
• Use the resubmit.resubmit{} function to resubmit a message

Here is an example using it in main():

local resubmit = require 'resubmit'

function main(Data)
   -- Caveat emptor - the refid needs to be for a valid message.  I have an admin
   -- user with user = 'kermit' and password = 'kermit' (replace with your own admin user details)
   -- replace SomeCondition with a condition (boolean) to specify when a message is to be repeated
   
   if SomeCondition then
      resubmit.resubmit{user='kermit', password='kermit', url='http://localhost:6543/', 
         refid='20130310-14420', message='MSH exploded', channel='My Channel'}
   end
end

———- and here is a test module ————-

local message = {}

local function Split(s, d)        
   local t = {}        
   local i = 0

   end        
   for sub, j in string.gfind(s, match) do        
      i = i + 1        
      t[i] = sub        
      f = j        
   end        
   if i~= 0 then
