After some time spent with exuberant-ctags and ripper-tags, I am switching over to universal-ctags. Ruby language and other languages like Golang is vastly improved over to exuberant-ctags and even ripper-tags. Here are my git hooks which I use for all my project checkouts. It’s fast, fluent and works across all my projects.
For navigation I stick with Vim, sometimes I use fzf.vim plugin together with fzf for terminal.
For longer coding sessions, I am trying GNOME Builder which looks great and every single release it is catching up with Submlime Text 3, except it is fully open source and it has usable Vim emulation. I’ve tried Atom and VSCode but these slow things are not for me.
