Project: Lifebook

Lifebook is a desktop task management application used for teaching Software Engineering principles. The user interacts with it using a CLI, and it has a GUI created with JavaFX. It is written in Java, and has about 13 kLoC.

Given below are my contributions to the project.

  • Added the ability to filter tasks due at/before a specified date/time
    • What it does: It allows users to search todos/meetings due at/before a certain date/time.
    • Justification: This feature improves the product functionality because a user may have a long task-list and it could be hard to search for specific deadlines.
    • Highlights: The implementation of this feature requires accessing the task-list and each task’s deadline.
  • Added ability to view tasks that are due soon (within 1 week)
    • What it does: At the bottom right-hand corner of Lifebook, a list of tasks is shown that are due 1 week from the current date/time.
    • Justification: This feature improves the product usefulness as the user will be more inclined to use Lifebook for the ease of looking at tasks that are due soon.
    • Highlights: It is a little challenging to incorporate the “Due by” panel into Lifebook, and I have to ensure that the “Due soon” panel is updated dynamically each time the user does a task operation.
  • Add a common tag to both a contact and a task
    • What it does: With a single command, you can add the same tag(s) to a particular contact and task.
    • Justification: This feature helps to speed up the process of adding a tag to a contact and a task if the user decides to have a commonn tag.
    • Highlights: Instead of writing all new code, I have used the “tagging” feature for a contact and task (individually) to reduce chance of bugs and overlaps.
  • Added ability to add a recurring task
    • What it does: A recurring task is created when a user includes the optional recurring/ field in adding a new todo/event. When a recurring task is marked as done, it will automatically generate another recurring task with the new deadline based on the recurrence field. (while the remaining details of the task remains the same)
    • Justification: This feature improves the product functionality as the user would not have to manually add recurring tasks every time.
    • Highlights: I have to ensure that the recurring task is generated properly after it is marked as done. We have considered whether should the “done” recurrence task be deleted automatically too, but we decide to leave it in case the user wants to trace back their done tasks.
