Project: E-Lister

E-Lister is a desktop application designed to help finance planning consultants manage large amounts of customer information. The user interacts with it using a CLI, within a GUI created with JavaFX. It is written in Java, and has about 20 kLoC.

Given below are my contributions to the project.

  • Feature I: Added filtering for persons by a combination of fields.
    • What it does: Allows for the user to search persons using (∩) combinations of any available fields.
    • Justification: The existing find command filters only by name, whereas the target user would need to search by other fields or even combinations thereof. filter enables such searches, and does so via regex - which is sufficiently powerful to nominally meet any expected needs, but also has basic functionality mimicking simpler input schemes.
  • Feature II: Added the ability to undo and redo an appropriate subset of commands.
    • What it does: Reverts previous commands in standard undo-fashion. Operates on all other commands which modify the data of Persons or the display thereof.
    • Justification: The option to undo provides a user an easy means to revert an undesirable command effect. Accordingly, a user can recover from typo errors, and can also attempt to use a command without having to heavily scrutinize its effect beforehand.
  • Feature III: Added the ability to freeze filters.
    • What it does: Halts the updating of the displayed list according to the current filter. (By default, if a person is edited to no longer satisfy the current filter, they would be automatically dropped from the display - freeze disables this.)
    • Justification: Reactive filters can be effective for the user and have been retained, but there are also scenarios where disabling continuous updates to the list would be preferred - to prevent repeated index changes, or Persons disappearing from the list.
