Take a look at the refactorings available in CLion: https://www.jetbrains.com/clion/features/code-generation-and...

Refactoring tools are incredibly powerful. For example, renaming a class method "foo". You can rename it yourself with a text editor, but now you have to manually update all the callers. You could try using search/replace, but what if several unrelated classes have a "foo" method? How do you only change the correct method calls? The IDE refactoring tool does this automatically.

Visual Studio with VAX (http://www.wholetomato.com/features/default.asp) is more than sufficient. The general objection to it historically has been "it's not free", but Visual Studio Code is Electron.io/node based, free, works on 3 of the major platforms, MSFT is in the process of enabling first-party support for using LLVM (I'm not sure if this is for the "Code" version of the traditional executable base --which is also available for free in the "Express" mind you) so that excuse isn't really valid anymore. If you're writing C# and not C++, then Resharper from IntelliJ is going to do you better probably. Speaking of which, JetBrain's CLion is way better than VIM w/r/t refactoring, intellisense, auto-complete, etc, not too surprising really since that's what they're famous for. Refactoring C in general is really trivial compared to the template messes I'd imagine a compiler would struggle with though. I'm not sure if they have a community edition but they offer 30 day trials IIRC and probably student discounts if you're not yet employed.

I use mostly eclipse, so maybe other IDEs already have it.

* Extract superclass/interface which will work on the whole codebase * Support for NVI - rename, change parameters, convert to virtual interface and back * code duplication detection (maybe exists but I never found sufficient one)
