The editor war is the rivalry between users of the Emacs and vi (now usually Vim, or more recently Neovim) text editors. The rivalry has become an enduring part of hacker culture and the free software community.
The Emacs versus vi debate was one of the original "holy wars" conducted on Usenet groups,[1] with many flame wars fought between those insisting that their editor of choice is the paragon of editing perfection, and insulting the other, since at least 1985.[2] Related battles have been fought over operating systems, programming languages, version control systems, and even source code indent style.[3][4]
