Project: Trackr

Trackr is a desktop application used to keep track of order, suppliers and tasks. The user interacts with it using a CLI, and it has a GUI created with JavaFX. It is written in Java, and has about 10 kLoC.

Given below are my contributions to the project.

  • Code contributed: RepoSense link

  • Contribution to code base
    • Initial refactoring of Supplier from Person
      • Justification: This improves the product because the differentiation between Supplier and Person fits the use case of our product.
    • Refactor Order to have a reference to MenuItem
      • Justification: This association is needed as users should only be able to create orders from pre-existing MenuItem.
      • Highlight:
        • Adapt Storage and JSON files to support MenuItem nested within Order
        • Generate total profits and sales from each order and all orders
        • Profits and sales responsive to changes in OrderQuantity and OrderItem
        • Rewrite relevant test cases for Order
    • Overhauls Ui
      • Highlights:
        • Refactor into packages
        • Cosmetic changes using CSS
        • Added tabbed views for different data
    • New feature: TabCommand that allows users to switch between tabs
      • Justification: Like most applications, users can use CTRL + TAB or ARROW KEYS to cycle through area of focus. This added feature allow users to skip tabs while using a verbose command. This also further optimises the product for CLI use.
      • Highlight: Used the Observer / Observable pattern with JavaFX SimpleIntegerProperty to listen to changes in the selected tab index. This decouples TabCommand in Logic from Ui and enforces Law of Demeter. Some commands such as list/find also snaps to relevant tab for better user experience.
