Neovim is a project that seeks to aggressively refactor [Vim](https://www.vim.org/) in order to:

- Simplify maintenance and encourage [contributions](CONTRIBUTING.md)
- Split the work between multiple developers
- Enable [advanced UIs] without modifications to the core
- Maximize [extensibility](https://neovim.io/doc/user/api-ui-events.html#api-ui-events)

See the [Introduction](https://github.com/neovim/neovim/wiki/Introduction) wiki page and [Roadmap]
for more information.

Install from package
--------------------

Pre-built packages for Windows, macOS, and Linux are found on the
[Releases](https://github.com/neovim/neovim/releases/) page.

[Managed packages] are in [Homebrew], [Debian], [Ubuntu], [Fedora], [Arch Linux], [Void Linux], [Gentoo], and more!

Install from source
-------------------

See [BUILD.md](./BUILD.md) and [supported platforms](https://neovim.io/doc/user/support.html#supported-platforms) for details.

The build is CMake-based, but a Makefile is provided as a convenience.
After installing the dependencies, run the following command.
```bash
make CMAKE_BUILD_TYPE=RelWithDebInfo
sudo make install
```

To install to a non-default location:
```bash
make CMAKE_BUILD_TYPE=RelWithDebInfo CMAKE_INSTALL_PREFIX=/full/path/
make install
```

CMake hints for inspecting the build:

- `cmake --build build --target help` lists all build targets.
- `build/CMakeCache.txt` (or `cmake -LAH build/`) contains the resolved values of all CMake variables.
- `build/compile_commands.json` shows the full compiler invocations for each translation unit.

Transitioning from Vim
--------------------

See [`:help nvim-from-vim`](https://neovim.io/doc/user/nvim.html#nvim-from-vim) for instructions.
