Use a respond as a fallback

Hey guys,

We have a service that we can chat with the bot (AI) and we don’t want hubot calling it when other plugins already did something.

That’s the plugin:

module.exports = (robot) ->
  robot.respond /(.+)/i, (msg) ->
    msg
      .http("http://www.ed.conpet.gov.br/mod_perl/bot_gateway.cgi")
      .query(server: "0.0.0.0:8085", charset_post: "utf-8", pure: 1, msg: msg.match[1])
      .get() (err, res, body) ->
        msg.reply body.replace(/<[^<>]*>/g, "")

If I have another plugin like this one:

module.exports = (robot) ->
        uis = [
                "http://2.bp.blogspot.com/--Tt_oRekUSE/T62ZFQF_kdI/AAAAAAAAOvk/0BmpdLRxe0U/s1600/meme+UI+colorido.png",
                "http://youpix.com.br/wp-content/uploads/2012/01/ui.jpg"]
        robot.hear /\bui\b/i, (msg) ->
                msg.send msg.random uis

And send a message like hubot ui it will call both.

That’s possible? I mean, a fallback respond that got called only when no other respond matched?

One workaround is:

• use msg.finish() in script to mark a message so it doesn’t get processed by any other listeners
• make sure the ‘catch all’ respond is the last script defined (ie rename it to be like ZZZ_somescript.coffee

With that, hubot ui would indicate the message is done processing, so the other listener doesn’t fire.

I’d definitely be open to something specifically to handle respond blocks that aren’t answered. It’d be a great thing to hook into help.coffee, as people often say commands at hubot and it’s frustrating when you don’t know if you messed it up, or it’s just working, or it was just silent. Not sure on best name, but respondFallback is a decent start.
