I can generally use macros in vim + vim integrations for things like ag or rg to do refactorings fairly easily: sure, it's not as automatic as Intellij, but it's not bad either.

Also, depending on the language, the tooling in Emacs can get all the other IDE features you are talking about: for haskell there's ghc-mod + intero, for common lisp there's slime, etc. if you install the appropriate plugins and then use something like Syntastic/Flycheck, you can have all the nice editing abilities of vim/emacs as well as most of the useful parts of an IDE's language support.
