Question 5

Is nui.nvim compatible with Vim or only Neovim?

Accepted Answer

nui.nvim is designed specifically for Neovim and requires Neovim 0.5.0 or higher. It relies on Neovim's Lua API, so it is not compatible with Vim or other editors.

What are the performance implications of using nui.nvim?

Accepted Answer

As a higher-level abstraction over Neovim's API, it may add some overhead compared to low-level calls, but for most UI plugins, the convenience and maintainability outweigh minor performance costs.
