#9993 UI/ext_messages: learn more message kinds8ed54bbec3
#9547 proper multiline error message for rpcrequest, API wrappers Lua This release introduces "Nvim-Lua standard library". See ":help lua-stdlib".89d7e24891
#9463 Lua stdlib: vim.inspect, string functions8e941c59ec

#10123 Lua: introduce vim.loop (expose libuv event-loop)81e1dbca99
#10120 Lua: vim.schedule(cb)1f54f68732
#10688 Lua: minimal UTF-16 support needed for LSP6fb0020df4
#10513 Lua encoding supportc0993ed343
Lua: support getting UTF-32 and UTF-16 sizes of replaced textb0e26199ec
Lua: add {old_byte_size} to on_lines buffer change event UI: - The Nvim 0.3.4 UI protocol introduced line-based updates instead of legacy char-based updates. Nvim 0.4 continues to evolve the UI protocol. See ":help ui". Legacy UI clients are supported. See ":help api-contract".9a1675b065
#6619 Floating windows - Can be (re)positioned, anchored, external. - Are real windows showing real buffers. No shortcuts, hacks, or compromises. - Support all features and API of normal windows, plus more.6427894d89
#8455 Multigrid: "windows drawn on separate grids" - Windows are logically isolated internally. - Windows are sent to UIs as distinct objects, so that UIs can control layout instead of being stuck with the classic TUI layout. - Per-window font-size, dimenions, line-spacing. - Compositor: Internal subsystem for composing grids.3855204f58

#9571 UI: 'pumblend' option for semi-transparent popupmenuc403a95a52
#9446 Visual: highlight char-at-cursor - Traditionally Vim's visual selection does "reverse mode", which perhaps conflicts with the non-blinking block cursor. But 'guicursor' defaults to a vertical bar for selection=exclusive, and this confuses users who expect to see the text highlighted. :terminalfc27dc98d7

#8349 edit.c: Disable indent during completion58f505dc74
#9829 startup: remove TUI init special-case Historically Vim/Nvim does backflips to handle input and show messages before a UI is available. This logical contradiction was already fixed for remote UIs (#9024c236e80cf3
). Fixing it also for the TUI avoids problems on Windows, simplifies the logic, and avoids races like #9959.

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.

- Modern GUIs
- API access from any language including C/C++, C#, Clojure, D, Elixir, Go, Haskell, Java, 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

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
The build is CMake-based, but a Makefile is provided as a convenience.
make CMAKE_BUILD_TYPE=RelWithDebInfo
sudo make install
To install to a non-default location:
make CMAKE_INSTALL_PREFIX=/full/path/
make install
To skip bundled (third-party/*
) dependencies:
- 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 sudo luarocks build mpack sudo luarocks build lpeg sudo luarocks build inspect
- Build with
USE_BUNDLED=OFF
:make CMAKE_BUILD_TYPE=RelWithDebInfo USE_BUNDLED=OFF sudo make install
To inspect the build, these CMake features are useful:
cmake --build build --target help
lists all build targets.build/CMakeCache.txt
(orcmake -LAH build/
) 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.
Transitioning from Vim
See :help nvim-from-vim
for instructions.
