The Sugar chat activity

What is this?

Chat is an activity used to exchange messages with friends or classmates. You can chat about a topic you are studying or you can share something private that happened in your life.

How to use?

Chat is part of the Sugar desktop. Please refer to;

chat's Issues

Transfer project to sugarlabs

Please check out https://wiki.sugarlabs.org/go/Infrastructure_Team/Migrating_to_GitHub and transfer this repo to https://github.com/sugarlabs :)

Issue with user mode switching

When the connection to the chat room status (multiuser mode) is activated, it is not possible to click the button on the left to return to single-user mode; the only option is to exit the chat room.

Feature: drawing and quoting

Some of the original design features not yet implemented are drawing and quoting.

• increase the height of the entry widget and accept touchscreen or mouse drawing, as well as text,
• transmit the drawing and text to the shared activity instance,
• receive and render both the drawing and the text,
• add a clear entry button to the entry widget,
• in the chat history, for each transmission add a quote button, which will load the entry widget with the drawing and text.

User Feedback Integration

Create a mechanism for collecting user feedback within the chatbot interface and incorporate it into the model training process for continuous improvement.

Feature: advise of connection progress

When a second or subsequent instance of the activity is started by others, there is little explanation for the delay that ensues. Like the Maze activity says "Joining a maze", say "Joining a chat" or whatever message is appropriate given the other messages in use now.

Community Engagement

Encourage community participation by organizing virtual hackathons or developer meetups to collaborate on enhancing the chatbot functionality and expanding its feature set.

Prevent user from sending smileys when disconnected

Users are able to send smileys when disconnected. Like sending text, sending smileys should also be disabled when the user isn't connected.

Tested on:
Sugar 0.117-3, Debian Bullseye
Sugar 0.117, Sugar Live Build
OLPC OS 18.04

Warnings on Ubuntu 19.04

When joining a shared activity, both the inviter and the responder see these log warnings;

(sugar-activity:10643): Pango-WARNING **: 17:01:12.866:

  the offending font is 'Noto Color Emoji 109'

Bug Fix

Issue where the chatbot occasionally fails to respond to user queries due to a timeout error, investigate and fix the root cause to ensure consistent performance.

Performance Optimization

Optimize the chatbot's response time by implementing caching mechanisms or improving the efficiency of natural language processing algorithms.

Security Enhancement

Conduct a security audit to identify potential vulnerabilities in the chatbot integration and implement measures to safeguard user data and privacy.

Loss of focus on up arrow key

Reproducer: be connected and chatting with others, decide to repeat what you said, and press the up arrow to do it.

Observed result: focus leaves the input text widget, and any further key presses make a beep noise.

Expected result: either no effect of up arrow key, or previously sent lines should be offered for editing.

Feature: searching

One of the original design features not yet implemented is searching.

• add a search widget to the tool bar with shortcut ctrl+f which highlights the first result and if necessary changes the scrollback position to do so,
• add a search next widget with shortcut ctrl+g,
• add a search previous widget with shortcut shift+ctrl+g,
• add a activity shortcut esc which is to cancel the search and restore previous position,

Low priority; mixed TelepathyGLib and D-Bus API usage

Chat uses TelepathyGLib for operations, and the Toolkit will be using D-Bus API only.

We don't know for sure this is a problem, because it depends on internals of the two APIs.
