This is a console-based productivity app involving both To-Do Lists and Goal tracking. It allows users to create To-Dos, check them off, and filter the display between complete/incomplete items. It also allows for the creation of daily goals that the user can track their progress toward. The most unique feature, however, is the ability to set a goal for how many to-do list items the user wants to complete on a given day.
The purpose of writing this software is to become familiar with the Kotlin language's syntax and style, utilizing both functional and object-oriented programming paradigms. For example, the goals and todos are represented by classes inheriting from a parent class Task, while both are stored in encapsulated collections under subclasses of an abstract class ProductivityList. Meanwhile, the console menus are handled using Menu and MenuOperation classes, which accept and store anonymous functions to associate code to be executed with each menu item.
The latest feature developed is integration with Cloud Firestore as a means of cloud-based data storage. This (in theory) allows users to store updates to their todos and goals as edits are made.
While Cloud Firestore does have libraries made specifically for the Kotlin language, they are available only as Android libraries, included with Android Jetpack. As such, using them within a Kotlin-only project - i.e. no Android or Android Studio involved - proved to be impossible (or too difficult to be worth it). Instead, I used the libraries made for Java. This, however, proved to come with endless difficulties of its own. Kotlin models have to be converted to Java classes for proper storage and retrieval, which caused issues such as completely empty data sets being returned from the database. Because of this and other issues, at this time the app can currently only write to the database - it cannot read from, update, or delete any documents in the database.
That being said, the structure is as such: users are stored as documents within a users collection. Each user has an array of ToDo items and Goals attached, as well as necessary metadata. This type of nested document database proved to be very useful for this type of data storage, since no complex relational tables need to be made, and everything can be simply stored in hierarchical format.
