Neovim is a project that seeks to aggressively refactor Vim in order to:

- Simplify maintenance and encourage contributions
- Split the work between multiple developers
- Enable the implementation of new/modern user interfaces without any
  modifications to the core source
- Improve extensibility with a new plugin architecture

For lots more details, see
[the wiki](https://github.com/neovim/neovim/wiki/Introduction)!

### What's been done so far

- Cleaned up source tree, leaving only core files
- Removed support for legacy systems and moved to C99
    - Removed tons of `FEAT_*` macros with [unifdef]
    - Reduced C code from 300k lines to 170k
- Enabled modern compiler features and [optimizations](https://github.com/neovim/neovim/pull/426)
- Formatted entire source with [uncrustify]
- Replaced autotools build system with [CMake]
- Implemented [continuous integration] and [test coverage]
- Wrote 100+ new unit tests
- Split large, monolithic files (`misc1.c`) into logical units
  (`path.c`, `indent.c`, `garray.c`, `keymap.c`, ...)
- [Implemented](https://github.com/neovim/neovim/pull/475) job control ("async")
- Reworked out-of-memory handling resulting in greatly simplified control flow
- Merged 50+ upstream patches (nearly caught up with upstream)
- [Removed](https://github.com/neovim/neovim/pull/635) 8.3 filename support
- [Changed](https://github.com/neovim/neovim/pull/574) to portable format
  specifiers (first step towards building on Windows)

### What's being worked on now

- Porting all IO to libuv
- Lots of refactoring
- A VimL => Lua transpiler
- Formatting with `clint.py`
- msg-pack remote API

### How do I get it?

There is a formula for OSX/homebrew, a PKGBUILD for Arch Linux,
and detailed instructions for building on other OSes.
