Summary of Contributions

Major Enhancement: Implemented feature to edit tasks

• What it does:
  • It allows the user to edit a chosen task from the list of tasks.
  • The index of task that user edits does not change after editing.
• Justification:
  • Improves usability of the tracking app as it allows users to edit any changes to their Assignments or Events.
  • Users will not need to delete an Assignment or Event before adding a new Assignment or Event if there are any changes to details of the tasks.
  • For events that are repeated, editing such events will keep the “repeating” indicator of the event.
• Highlights:
  • This enhancement is especially useful in a tracking app where tasks details are dynamically changing. It allows for quick and hassle free changing of the details.
  • Implementing the edit feature was difficult because a separate Ui prompt has to be implemented in the command to accept new user inputs.
  • Furthermore, due to implementation limitation of AssignmentCommand and EventCommand feature, I could not use the existing implementations to have instances of assignment or event class.
  • Hence, within the EditCommand class, I have to implement methods that return assignment and event task types.
  • This was quite hard to implement as I had to understand what attributes the asssignment and event task types were to ensure that the user is able to edit the tasks’ attributes smoothly.
  • We discovered later that there is a bug when editing repeat event task types. When repeat event task types are edited, the event no longer stays as a repeat event and reverts back to just being an event task type. This was fixed by adding checks to indicate whether task to be edited is a repeat event and another method to preserve all the repeat event attributes.
  • Refer to Pull Request #194 for bug fix.
  • Another bug was also found when we tried to enter in a different task type when editing a task. i.e. Tried to edit an Assignment task to an event task and vice versa. The program shows a success message but it did not show up in the task list.
  • I subsequently fixed the bug by disallowing users to edit a task type to a different type. #213
• Credits:
  • Credit to the team for helping me to catch the bugs related to edit command.
