Answer 3

I write a lot of C/C++ code in vim. The most common refactoring that I do is renaming variables, class names, etc. Usually, I use :bufdo :%s/source/dest/g to do a search/replace in files, which is almost the same as renaming provided by big IDE's.
However, in my case, I found that I usually rename similar entities, spelled in different cases (i.e CamelCase, snake_case, etc.), so I decided to write a small utility to help with this kind of "smart-case" search/replace, it is hosted here. It is a command-line utility, not a plugin for vim, I hope that you can find it useful.
