Neovim

Neovim is a refactor, and sometimes redactor, in the tradition of Vim (which itself derives from Stevie). It is not a rewrite but a continuation and extension of Vim. Many clones and derivatives exist, some very cleverβ€”but none are Vim. Neovim is built for users who want the good parts of Vim, and more.

Goals

  • Enable new contributors, remove barriers to entry.
  • Unblock plugin authors.
  • Develop first-class Lua/LuaJIT scripting alternative to VimL.
  • Target all platforms supported by libuv.
  • Leverage ongoing Vim development.
  • Optimize out of the box, for new users but especially regular users.
  • Deliver consistent cross-platform experience.
  • In matters of taste/ambiguity, favor tradition/compatibility...
  • ...but prefer usability if the benefits are extreme.

Non-goals

  • Turn Vim into an IDE
  • Limit third-party applications (such as IDEs!) built with Neovim
  • Deprecate VimL
  • POSIX vi-compatibility
