Using VIM delights me everyday. However, I also work with Java codebases, and there Java IDEs are still relevant. I've tried a VIM plugin on IntelliJ IDEA, but it doesn't work well. I'd like to use the VIM keybindings with IDEA for the sake of speed and enjoyment, but it seems that I should first contribute quite a lot of code for the IDEA VIM plugin to get it working properly. How do you VIM lovers work with Java code bases?
