Time Travelling Without Worries But here's the best part - knowing the true nature of history, we can combo it with another cool feature of Vim - persistent undo - to be able to travel in time there and back without fear of losing anything! In other words, if you do: mkdir -p ~/.vim/undodir and then add: set undofile set undodir=~/.vim/undodir to your ~/.vimrc, you get a file-backed infinite undo. And even if you undo like a madman and then edit something, you will not lose your way back to where you’ve been. Which is pretty much a developer’s (or anyone’s, really) text-editing nirvana. Enhance you calm and enjoy a bit saner coding.
