I&#x27;m exclusively an emacs user, but I would definitely like better IDE functionality. I use the builtin fast jump-to-file and text based autocompletion, plus SilverSearcher powered text search and it is fine 90% of the time.<p>Still I would love to have working jump to definition&#x2F;declaration&#x2F;reference, type and context exact autocompletion, semantic based highlighting and on-the-fly error checking. I do not care much for refactoring support except maybe basic renaming help.<p>There is EDE, but in my experience it fails very quickly on anything beyond trivial projects. There are a few clang based indexing&#x2F;autocompletion engines (I favor rtags) which can do all of the above amazingly well, but they are not impressively fast and in my experience any setup I tried bitrots extremely quickly.
