FAQs

What are "Next Edit Suggestions" and how do they differ from inline completions?

Next Edit Suggestions (NES) are AI-powered suggestions that propose entire refactorings or multi-line changes anywhere in your file, offering "big picture" suggestions. This differs from inline completions, which typically suggest smaller, single-line code completions as you type.

Which AI CLI tools are supported by sidekick.nvim?

sidekick.nvim offers out-of-the-box support for popular AI command-line tools such as Claude, Gemini, Grok, Codex, and Copilot CLI. Its extensible nature also allows for integration with other AI CLIs, providing a versatile environment for AI-assisted coding.

What are the key requirements to use sidekick.nvim?

To use sidekick.nvim, you need Neovim version 0.11.2 or newer, the official copilot-language-server LSP server enabled with `vim.lsp.enable`, and a working `lsp/copilot.lua` configuration. Optional requirements include snacks.nvim for prompt selection and nvim-treesitter-textobjects for context variables.
