Step 14: Capture a comment

The user may leave a comment to the order, which can be any phrase. To capture an open-end phrase, we can use a slot with a greedy RegEx.

1. To the dialog script, add the getComment context with a command to capture the user’s comment:

   Dialog script

   let getComment = context(() => {
       intent('My comment is $(COMMENT* (.+))', p => {
           p.play(`I'll' take a note: ${p.COMMENT.value}`);
       });
   });
   

2. Update the intent in the getTime context: activate the getComment context from it and add another p.play() function to prompt the user to leave a comment:

   Dialog script

   let getTime = context(() => {
       intent('$(TIME)', '$(T now|asap|right now|as soon as possible)', p => {
           let time, date;
           if (p.T) {
               time = api.moment().tz(p.timeZone).add(30, 'minutes').format("h:mm a");
           }
           if (p.TIME) {
               time = p.TIME.value;
           }
           p.play(`We will deliver your order at ${time}`);
           // Prompting for leaving comments
           p.play('Any comments?');
           // Activating the getComment context
           p.then(getComment);
       });
   });
   
    let getComment = context(() => {
        intent('My comment is $(COMMENT* (.+))', p => {
            p.play(`I'll' take a note: ${p.COMMENT.value}`);
        });
    });

Now, you can try the dialog with different phrases for a comment.
