Vim-fork focused on extensibility and usability

Problem: Sometimes, when nvim sends the `win_viewport` event, for example when scrolling with visible folds on the screen, it reports the `scroll_delta` value one batch into "future". So when the client application is trying to show the new viewport it's not yet updated, resulting in temporary corruption / screen flickering. For more details see #23609, and starting from [this comment]( https://github.com/neovide/neovide/pull/1790#issuecomment-1518697747) in https://github.com/neovide/neovide/pull/1790,, where the issue was first detected. Note that some of the conclusions in those are not fully accurate, but the general observations are. Solution: When there are pending updates to a Window, delay the `win_viewport` UI event until the updates are sent. This ensures that there's no flush between sending the viewport and updating of the lines corresponding to the new viewport. Document the existing viewport behaviour (for cases where there are no extra flushes), give a hint about how applications can deal with the slightly surprising behaviour of the viewport event being sent after the updates. Fixes https://github.com/neovim/neovim/issues/23609 |

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 the Building Neovim wiki page 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.
