This Project Portfolio documents my contributions to MooLah, a project made in NUS' Software Engineering module.
My team, consisting of 5 Computer Science students, was tasked to enhance an existing project, Address Book Level 3. Over the course of the semester, we morphed the original Address Book code into MooLah, an expense tracker that accepts input through the Command Line Interface (CLI). We found many existing expense trackers on the market to be relatively troublesome and hence sought to create a hassle-free expense tracker specifically tailored to NUS students. MooLah has a clean and efficient Graphic User Interface (GUI) made from JavaFX, and supports many quality-of-life features such as autocompletion of input. At its core, MooLah allows users to easily manage their spending with the use of budgets, expenses, events and robust statistics calculations.
The following is a summary of my contributions to MooLah. I was mainly responsible for the development of events and time-based features.
-
Major enhancement: I added the ability to track events in MooLah.
-
What it does: This feature allows the user to add, edit and delete events, which are the user’s important future activities that they have to spend money on (e.g. a friend’s birthday). MooLah reminds the user of upcoming events, and on the day of the event, will automate the adding of the corresponding expense from the event.
-
Justification: Many of our users lead busy lives and may sometimes forget to input expenses from important events that they attend, or may forget these events altogether. My feature solves this issue by letting users input a future event; MooLah then automates the reminding and the eventual adding of the expense from the event. Such a 'fire-and-forget' implementation greatly enhances convenience for the user.
-
Highlights: Automating the reminding and adding of expenses from events requires MooLah to keep constant track of system time. I also had to work closely with my teammate who implemented the budgeting feature as every event, and its corresponding expense, had to fall under the correct budget.
-
-
Minor enhancements: I implemented several time-based features in MooLah.
-
Fully implemented the Timestamp field into MooLah’s expenses and events, hence allowing users to keep track of when exactly their expenses and events happen.
-
Implemented constant system-time checking in MooLah via the use of a timer that runs on a parallel thread. This allows MooLah to accurately refresh budgets and enables precise timekeeping of expenses, events and budgets. (#132)
-
Integrated, with some modifications, the third-party Natty library into MooLah. This allows MooLah to support natural language date-time parsing. (#132)
-
Improved the parsing and validity-checking of the Price field. (#216)
