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 advanced UIs without modifications to the core
• Maximize extensibility

See the Introduction wiki page and Roadmap for more information.

Features

• Modern GUIs
• API access from any language including Clojure, Lisp, Go, Haskell, Lua, JavaScript, Perl, Python, Ruby, and Rust
• Embedded, scriptable terminal emulator
• Asynchronous job control
• Shared data (shada) among multiple editor instances
• XDG base directories support
• Compatible with most Vim plugins, including Ruby and Python plugins

See :help nvim-features for the full list!

Install from package

Pre-built packages for Windows, macOS, and Linux are found on the Releases page.

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

Install from source

make CMAKE_BUILD_TYPE=RelWithDebInfo
sudo make install

To install to a non-default location, set CMAKE_INSTALL_PREFIX:

make CMAKE_EXTRA_FLAGS="-DCMAKE_INSTALL_PREFIX=/full/path/"
make install

To skip bundled (third-party/*) dependencies:

1. Install the dependencies using a package manager.

   sudo apt install gperf luajit luarocks libuv1-dev libluajit-5.1-dev libunibilium-dev libmsgpack-dev libtermkey-dev libvterm-dev libjemalloc-dev
   sudo luarocks build mpack
   sudo luarocks build lpeg
   sudo luarocks build inspect
   

2. Build with USE_BUNDLED=OFF:

   make CMAKE_BUILD_TYPE=RelWithDebInfo USE_BUNDLED=OFF
   sudo make install
   

CMake features:

• List all build targets:

  cmake --build build --target help
  

• Print all variable definitions:

  cmake -LAH
  

• build/CMakeCache.txt contains the resolved values of all CMake variables.
• build/compile_commands.json shows the full compiler invocations for each translation unit.

See the Building Neovim wiki page for details.

Vim is Charityware.  You can use and copy it as much as you like, but you are
encouraged to make a donation for needy children in Uganda.  Please see the

features.  The money goes to Uganda anyway.
