Overview

Finux is a Command-Line Interface (CLI) application that allows you to record your expenses, savings and loans all in one consolidated platform. It enhances the user experience by integrating of different features into one to remove the hassle of constantly using different applications.

Contribution to Implementation

ParserHandler

During the discussion phase, Mark and I have decided that the ParserHandler logic will contain no form of validation. The validation will be done when we are creating each command object itself. Following this approach, we reduce the coupling arising from validation to only under the command creation period via the constructor. Considering the future development of Finux, I have decided to follow the pairwise logic of how a command line interface would work. The pairwise logic ensure that, every option is followed by an argument with an empty string to indicate no argument provided. This will facilitate the validation process. I have also decided to use a third-party API, Apache Commons Lang 3.11, as it was easier to detect a collection of string containing the options.

ViewCommand

I have also implemented the ViewCommand where it would display each individual category amount. This was implemented via the options available to the user which are -e, -l, and -s. The initial thought was to only allow the view of each category but based on the feedback received, I decided to enhance the feature to display all the amount of with each category in a single command, introducing the 4th option -a.

HelpCommand

Since our product is similar to that of a CLI, I have decided to implement the help feature to display similarly to the man page of a CLI. The initial thought was to allow the target user to have a sense of CLI environment. However, after receiving some feedbacks on having aa less detailed help feature, I decided to allow the mixture of both user-friendly and CLI-based help feature. The more user-friendly approach will display the name, brief description, and format of the command while the CLI-based will display the name, synopsis, and description of the option and argument.

Contributions to UG

I have provided the team with a UG skeleton based on everyone User Guide from previous project. Apart from the skeleton, I have also documented the section on view feature and help feature.
