Is there a way to automatically remove duplicate functions in VSCode?

Hey everyone! I'm looking for a script or extension for Visual Studio Code that can automatically remove duplicate functions or methods from my code. I often use tools like ChatGPT to write new versions of my code, but then I have to manually sift through my codebase to delete the older versions. It would be way easier if I could just append the new functions/methods at the end of my script and then run something that cleans up the duplicates for me. Has anyone come across a tool that can help with this?

Honestly, why stress about duplicates? Just vibe-code! Focus on writing clean code when you can. If you seriously consider each function, you'll likely remember if you've written something similar before. Develop with intention, and donโ€™t let AI do all the work. If you've got real duplicates, most IDEs will flag them, but if they have the same logic even with different implementations, itโ€™s trickier to track down duplicates.

Honestly, if you're just adding AI-generated functions and aren't sure whether they already exist, maybe you should rethink your approach. A tool might not be the solution to this problem. Itโ€™s essential to understand the functions youโ€™re working with.

Consider using a linter instead of relying on AI for code generation. Itโ€™ll help you keep track of your functions better and manage your code quality effectively.

I'm a bit puzzled. If you're creating a new version of a function, shouldn't it replace the old one? You could just use the same name or rename instances easily in VSCode. A quick 'Find + Replace All' does the trick. Just click the magnifying glass in the left menu and reveal the replace option next to the search box. That way, itโ€™s pretty seamless!

You might want to look into Python linters. They can detect duplicate function definitions for you, which should save some time.
