Dialogflow: Forcing certain intents to be invalid given context

Asked 2020-Jun-03 at 02:08

I want to make knock knock jokes using dialogflow, but I found that I can trigger one knock knock joke from the context of another. For example I have the following intents:

knockknock: training phrase (knock knock joke), response (knock knock)
- whosethere: trainging phrase (who dat), response (annie, orange)
  - punchline-annie: training phrase (annie who), response (annie thing you can do I can do better)
  - punchline-orange: training phrase (orange who), response (orange you glad...)

If the bot responds with annie, I can respond with orange who and get the orange punchline to the joke. How can I prevent this from happening? I only want the orange punchline to be able to be called when the response from the whosethere intent was orange.

I think you need to look into how to send a responsive via fulfilment/webhook and how contexts work. In your whosthere intent, you could send a response via fulfilment and set the context appropriately. E.g.: if you answer with "annie", set an annie specific context (e.g. punchline-annie-context) and set punchline-annie-context as an input context for the punchline-annie intent. This way you ensure that punchline-annie can only be activated, if the whosthere response was "annie".

My chrome extension is not working on Edge

I have a piece of code which works fine on chrome. I did the following step mentioned here. I'm able to load it properly, but the code doesn't run properly. In the background console only the url gets printed, no other consoles or alerts work. Please any help will be appreciated ! Please

I tested and found that if we remove window.onload then the extension will work well in Edge Legacy. It will print all the consoles.

You could set content.script run at document_idle. It's equal to window.onload and you do not need to listen for the window.onload event. For more detailed information, you could refer to this article.

QUESTION

How to make a Chrome Extension sleep for a time and post message on port

Asked 2019-Aug-20 at 08:15

In my extension, I want the extension wait for a time, because it changes something in the content and it mustn't be fast. I am using a sleep function, it is just a loop that breaks when the time comes but it makes my computer really slow. I used setTimeout method, but the extension says "port is not defined", because the code goes on when the setTimeout method is run, but I think the port stops connection. So, do you have any idea how I can make the code sleep without ruining the computer?

Sleep function

Your sleep function doesn't actually sleep/wait, it just blocks the main thread of the page. In JavaScript the only proper way to sleep is setTimeout/setInterval and similar built-in functions.

Solution: don't use sleep() and simply pass the port to your timer callback as a parameter.

Chrome v64.

I want to send a message from content.js to popup.js.

I managed to send a message from popup.js to content.js. But how to do it the opposite way? I have also downloaded a sample extensions, which also don't work.

Do I have to add a special permission? I tried one time messaging and long running message channel.

From your code it looks like you are sending a message from your content script to the background and popup script, as opposite to what you described.

Sending a message from your extension to content script requires you to use chrome.tabs.sendMessage, see https://developer.chrome.com/apps/messaging

QUESTION

Exceptions in Swing from helper classes

Asked 2018-Feb-26 at 03:02

I am working on a homework assignment to convert this Java Tutorial of the Knock Knock application to a Swing GUI application and use multithreading.

I have helper classes that are throwing Exceptions. These classes do not extend JFrame and I can't create new JOptionPane to show the exception. How would you show that Exception to the user?

For example: I have a class that loads the jokes from two text files (one for the clues and one for the answers). If the text files cannot be found in the location I expect, I am throwing a NullPointerException. Because this is a helper class it is not extending JFrame. How would I relate that message to the user? Do I just reference the javax.swing.JOptionPane showMessageDialog method like I have it in my code below or I can have another proxy class that catches exceptions and shows them?

...

ANSWER

Answered 2018-Feb-26 at 03:02

Instead of using Swing components in business layer you can pass on the exceptions and handle it separately.

Have some custom Exception handler class where you can handle Runtime/Checked/Custom exceptions.
