Using ALE Rainbow chatbot library, i'm trying to change the value of next route in onMessage() callback.

Is-it possible to specify some additionals parameters in done() function to do that ? 

Is there any oher documentation available more complete than this one: https://github.com/Rainbow-CPaaS/Rainbow-Chatbot

Thanks

  Hmm, looking at the docs in GitHub: https://github.com/Rainbow-CPaaS/Rainbow-Chatbot

  Will this resolve your question:

  Rerouting

  When you call the done() function, you can pass a parameter corresponding to the name of the next action to execute. You scenario will be rerouted to this step and will continue.

  chatbot.onMessage((tag, step, content, from, done) => {
  
      if(step === "aStep" && content==="yes" && from.jid==="ajid@adomain.com") {
          done('special_step');
      } else {
          done();
      }
      
  }, this);
  

  In that sample, depending on the step, the user and the answer received, a rerouting is done to the step special_step. For other cases, the normal next step is executed.

  ?

  Thanks for your answer pascal,

  What I'm looking for is not only rerouting to another step, but also changing the text of next step. (Passing an additional parameter to the done() function to override the text of next step in fact)

  Ok

  Problem here is, it uses internaly the Promise "resolve", why may only carry one argument.
  But you can for example patch the code in Rainbow-Chatbot\index.js, line 172 and next to handle this in

  routedStep

  • nothing,(resolve())
  • or a "next step" (resolve("next step"))
  • or an Array of ["next step", args] (resolve(["next step", args]) with args in json format) and store the args somewhere you need in

  work

  Best regards,
  Pascal
