Contributing to a new project always brings a mix of challenge and reward. Recently, I embarked on a significant milestone: writing clean, understandable code within a collaborative environment. This experience reinforced a crucial lesson I’ve learned since beginning my programming journey: a good codebase isn’t just about functionality, but equally about clear communication, meaningful comments, and self-documenting code.

The initial hurdle involved setting up my groupmate’s project, a process that proved to be a learning experience in itself. Clear communication regarding package and libgit2 dependencies was paramount. Thanks to effective teamwork, we successfully configured the environment, paving the way for the development phase.

Diving into an unfamiliar codebase can be daunting. My initial instinct was to meticulously examine every module and line of code, an approach I quickly realized was unsustainable. Instead, I shifted to a more strategic method: taking notes on module functions and class names, using a traditional pen-and-paper approach. This allowed me to grasp the overarching design and identify that the key to writing effective new code was to integrate seamlessly with the existing architecture without altering the core logic.

My contribution involved specific technical implementations, particularly utilizing the std::chrono library for timestamp management. This modern C++ library proved more intuitive than the C-style ctime for calculating time differences and identifying recent files, such as those within the last seven days.

Here’s a snippet demonstrating its application:

constexpr int MAX_RECENT_DAYS = 7;
//get current time and calculate the difference
std::chrono::system_clock::time_point now = std::chrono::system_clock::now();
std::chrono::system_clock::time_point daysAgo =  now - std::chrono::hours(24 * MAX_RECENT_DAYS);

While auto could have been used, explicitly stating types here enhanced clarity for this specific use case. Furthermore, I leveraged C++ algorithms and lambda functions to maintain code conciseness and efficiency, a practice highly recommended for avoiding manual loops. For instance, std::remove_if combined with a lambda provided an elegant solution for filtering files based on recency:

auto end = std::remove_if(scanResult.files.begin(), scanResult.files.end(),
        [](const FileEntry& file) {
            //checking the File via function
            return !isFileRecent(file.path);
        });

This approach demonstrates a preference for functional programming paradigms where appropriate.

Another significant learning curve involved navigating Git. A failed git push due to an unpulled remote branch highlighted the importance of regularly syncing local repositories. This incident also provided an opportunity to learn how to effectively amend commits, a valuable skill for maintaining a clean commit history. Day by day, my apprehension towards advanced Git operations continues to diminish.

This project represented one of the most challenging, yet rewarding, periods in my coding journey. It demanded not only technical prowess but also strong communication skills, particularly when providing detailed setup instructions for my groupmate. I plan to enhance my project’s README with these new insights. I also want to express my gratitude to my groupmate for their professional approach and collaborative spirit.

Looking ahead, this experience has underscored the importance of minimizing project dependencies to streamline setup processes. I am now seriously considering TypeScript or JavaScript for future projects to mitigate such “nightmares,” aiming for a more independent and easily deployable development environment. The lessons learned about dependencies will undoubtedly influence my architectural decisions going forward.
