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 C/C++, C#, Clojure, D, Elixir, Go, Haskell, Java/Kotlin, JavaScript/Node.js, Julia, Lisp, Lua, Perl, Python, Racket, Ruby, 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, and :help news for noteworthy changes in the latest version!
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, Void Linux, Gentoo, and more!
Install from source
See BUILD.md and 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.
make CMAKE_BUILD_TYPE=RelWithDebInfo
sudo make install
To install to a non-default location:
make CMAKE_BUILD_TYPE=RelWithDebInfo CMAKE_INSTALL_PREFIX=/full/path/
make install
CMake hints for inspecting the build:
cmake --build build --target helplists all build targets.build/CMakeCache.txt(orcmake -LAH build/) contains the resolved values of all CMake variables.build/compile_commands.jsonshows the full compiler invocations for each translation unit.
Transitioning from Vim
See :help nvim-from-vim for instructions.
