The main feature that I miss from CLion is the ability to refactor. In CLion you can rename a class, and all of its usages, declarations, etc. will be renamed.<p>The most useful thing CLion can do is change the signature of a function, and its corresponding implementation and header declarations will be changed. So, you can rename a parameter and its declaration and implementation will be renamed for you, or you can delete a parameter, or change the type of a parameter, and CLion will change all its usages&#x2F;definitions&#x2F;declarations for you. All of this effects across all files in your project, so if you&#x27;re in a .cpp file and you change the function signature, its declaration in the corresponding .h file will change as well.<p>(I believe you can do all of this in Eclipse as well)<p>Sadly I have yet to see a vim&#x2F;emacs configuration that gets anywhere near the level of Eclipse&#x2F;CLion.
