What’s better than wrangling with code complexity? Doing it across multiple files, all while making sure your tool never explodes into a fiery ball of errors! That’s right, I’m talking about the journey of adding multi-file support and error handling to my beloved project, Code Complexity Pro.

Feature 1: Multi-File and Directory Support – The More, the Merrier!

Let’s face it—analyzing just one file is pretty basic. Why not throw in a whole project directory? Better yet, throw in a few directories and some standalone files for good measure! That's exactly what I did with d309865.

How it Works:

Now, Code Complexity Pro can take in multiple files or directories and dig deep into them like an unstoppable code-sniffing hound. It doesn’t care whether you’ve passed one Python file or a whole nest of them buried in directories—it’ll find them all and give you the complexity breakdown.

A Cool Example:

Let’s say you’ve got a project folder and two files floating around. Just throw them all in and watch the tool work its magic! Every single relevant file gets analyzed.

Feature 2: Error Handling – The “Oh No” Moments

Ah, errors. They sneak in when you least expect them: a file doesn’t exist, a directory is empty, or your cat walks over the keyboard and types something crazy. So, in 37e20e8, I suited up and added robust error handling that makes Code Complexity Pro graceful in its failure.

Now, instead of cryptic Python tracebacks, you get well-crafted error messages delivered right to your terminal. Plus, the tool won’t just crash and burn if one file is missing—it will keep chugging along, processing all the files it can while kindly telling you which one made it stumble.

Real-World Scenario:

Let’s say you tried analyzing a file that doesn’t exist. No worries—the tool simply says, “Hey, that file isn’t here,” and moves on. You’ll get an error message, and it exits cleanly. And if other files are valid? It’ll analyze those while giving you a heads-up about the missing ones.

Behind the Scenes – Git Adventures and Branching Madness

You know what’s even more fun than coding these features? Watching the magic of Git manage my multiple branches as I tackled these two monsters separately.

For multi-file support, I worked on issue-7. For error handling, I spun up issue-8. Keeping these branches separate was like having two parallel universes—each focused on a single mission, with no crossover until the great convergence, aka the merge.

And oh, what a merge it was! After testing each feature, I brought them together in a beautiful symphony of code. Did I run into merge conflicts? Of course! But nothing a little Git elbow grease couldn’t fix. And soon, both features lived harmoniously in the main branch, ready to make developers’ lives easier.

Key Lessons Learned (and Fun Times Had)

1. More Files, More Fun: Working with directories and multiple files gave me a real appreciation for Python’s os and sys modules. Recursion and file handling are way cooler when you're processing whole projects!

2. Errors Can Be Fun: Well, not always, but making your tool gracefully handle errors without breaking is a skill I’m proud of. It’s like teaching a toddler to say “please” when asking for candy. Your code doesn’t scream anymore—it asks nicely, and if something’s wrong, it tells you politely.

3. The Power of Git: Branching, merging, and dealing with conflicts taught me how to handle multiple simultaneous code changes like a pro. When the merge conflicts hit, I wasn’t fazed—I handled them, laughed in the face of chaos, and moved on.

Wrapping Up: My Code Complexity Pro is Ready for Action!

With these two features in place, Code Complexity Pro is better than ever. It’s smarter, more powerful, and far more polite in telling you what’s wrong. The journey from single-file analysis to full-project support and robust error handling has been a wild ride, but worth every moment.

So next time you’ve got a whole project full of code, just hand it over to Code Complexity Pro and let it work its magic. And if something goes wrong? Don’t worry—this tool has your back!
