[brandtdaniels]

utterances not keeping braces around slot names when generating content.
Also slots are optional, please remove if empty.

From this:

    {
        "slots": {"date": "AMAZON.DATE", "city": "AMAZON.US_CITY"},
        "utterances": [
            "what movies are playing {on |} {date}",
            "what movies are playing {in|near|around} {city}",
            "what movies are playing {in|near|around} {city} {on |} {date}",
            "what movies are playing {on |} {date} {in|near|around} {city}"
        ]
    }

Generates this:

{
   "intents": [
      {
         "intent": "AMAZON.HelpIntent",
         "slots": []
      },
      {
         "intent": "AMAZON.StopIntent",
         "slots": []
      },
      {
         "intent": "AMAZON.CancelIntent",
         "slots": []
      },
      {
         "intent": "GetMoviesIntent",
         "slots": [
            {
               "name": "date",
               "type": "AMAZON.DATE"
            },
            {
               "name": "city",
               "type": "AMAZON.US_CITY"
            }
         ]

I don't know if master currently supports outputting curly braced slot names in the utterance list. You could look at #5 to see if it accomplishes what you are looking for. In that PR I introduce a special syntax where typing {-|city} in the input string would produce {city} in the output list every time it shows up.

[brandtdaniels]

I really think it could be coded in an intelligent matter where it automatically adds the braces to the slot keys if they are not already present, or keeps them if they are.

[MaxwellPayne]

If you have an intelligent fix, go ahead and submit a PR. Either way, this repo needs to come to some sort of consensus on how to handle the curly brace expressions. #2 also offers a potential fix, but so far none has been incorporated.

Agreed. I've been meaning to dive into this in more detail, but haven't yet had time with the holidays. The biggest concern I have is introducing new syntax, or doubling up on functionality that alexa already provides. I'll need to read up on the new amazon feature to understand the consequences, etc.
