Project: TAvigator

TAvigator is a desktop address book application used by Teaching Assistants (TAs) to keep track of students’ contact details and attendances. It aims to provide a one-stop platform curated for TAs teaching Computer Science courses in the National University of Singapore, streamlining the teaching process for them.

The user interacts with it using a CLI, and it has a GUI created with JavaFX. It is written in Java.

Given below are my contributions to the project.

  • New Feature: Added the list attendance command
    • What it does: Displays a summary of attendance records and list of absentees from the chosen tutorial group in the course for the week chosen. If tutorial group is not specified, displays the summary and absentees for the whole course. If there are students whose attendances are not marked for the week, it shows the names of students with unmarked attendances and displays all students in the specified group.
    • Justification: The feature allows the user to quickly obtain a summary of attendance records, the list of absentees for the week and their contact details or, if attendances are incomplete, the students with unmarked attendances, without having to manually look for them.
    • Highlights: The implementation of the ListAttendanceCommand was rather tedious because it underwent many iterations, as its implementation was closely related to that of Attendance and how course codes and tutorial group IDs were handled, both of which were changed a number of times.
  • New Feature: Added the delete all command
    • What it does: Allows the user to delete all students from the chosen tutorial group in a course at once. If the tutorial group is not specified, it deletes all students in the course.
    • Justification: The feature allows the user to easily delete a group of students, reducing the hassle of having to do so one by one.
    • Highlights: The implementation of this feature was tricky as it was implemented as part of an existing DeleteCommand. As such, more problems were encountered when implementing the parser. Also, a large variety of errors had to be handled properly.
  • New Enhancement: Implemented attendance saving
    • What it does: Allows the marked attendance to be saved into the tavigator.json file.
    • Justification: Without this, the marked attendances will be lost upon closing TAvigator.
    • Highlights: The implementation of this feature was straightforward but required changes to many aspects of the codebase.
