PROJECT: MooLah

Overview

MooLah is a Command Line Interface (CLI)-centered expense tracker poised to be hassle-free and tailored for students of National University of Singapore (NUS). This project is developed by me and 4 Computer Science students in NUS. In developing the project, we were initially tasked to enhance or morph an existing project, Address Book Level 3. Throughout the semester, we decided to morph the original codebase into MooLah and developed features for it incrementally. Although MooLah is CLI-centered, it also has a neat Graphical User Interface (GUI) made by JavaFX code, and supports features such as autosuggestion to achieve the intended convenience of using MooLah.

Summary of contributions

Major enhancement

I implemented the functionality to undo and redo commands that have been executed by the user. The details are as follows:

  • What it does: The functionality enables the user to undo commands that have been executed one-by-one. Commands that have been undone can be reverted back by using the redo command, provided that the user has not executed any new commands at the time.

  • Justification: This component improves the application significantly as a user can make mistakes in commands and the component helps the user amend them.

  • Highlights: This enhancement affects existing commands and commands to be added in future, as commands can now be either undoable or non-undoable in nature. It required a thoughtful analysis of design approaches and resource trade-offs, namely in computation time versus memory. The implementation too was challenging as it hinges on the immutability of the data structures of the model, and persistence of model states throughout execution.

Minor enhancements

Other than the major enhancement described above, I have also:

  • Added a new command that adds an expense from the list of NUS canteens' food and drinks supported by MooLah. This command is a shorthand form of the general add expense command tailored for NUS students.

Other contributions

Project management

As the person-in-charge for project integration, my responsibility is to streamline the process of proposing code changes and contributions, and to preserve the integrity of the codebase. The measures I have taken to achieve that, are namely:

  • Ensured the master branch is protected from rogue code pushes

  • Made passing Travis build a requirement for merging pull requests to ensure the integrity of the master branch.

  • Configured Coveralls to post coverage status to pull requests after passing Travis build with a warning if coverage drops by 5%.

  • Set the requirement for one teammate approval to be able to merge pull requests to improve codebase quality.

Improvements to existing components

I improved some aspects of the original codebase to better complement my enhancements and to improve the quality of the project as a whole. For the improvements, I have:

  • Separated command validation from execution #85

Community

As part of a project community with my teammates, I have done the following as contributions to the group discussion:

  • Reviewing pull requests (with in-depth comments): #62, #89

Integration Tools

I have incorporated third-party tools to help automate or manage the development of the project. In summary, I have:

  • Integrated Coveralls to the team repo to keep track of the project’s line coverage.

  • Integrated Trello to manage project issues and backlog throughout the development process.
