Описание тега neovim
Neovim is a fork of Vim that aims to improve upon Vim's out-of-the-box experience and allow for more powerful plugins and GUIs.
Neovim is in currently heavy-development mode, so for now, it is not yet ready to download or run now with all the features.
It is important to emphasize that this is not a project to rewrite Vim from scratch or transform it into an IDE (though the new features provided will enable IDE-like distributions of the editor). The changes implemented here should have little impact on vim's editing model or vimscript in general. Most vimscript plugins should continue to work normally.
