The exact list of available models depends on your GitHub Copilot settings and the models provided by GitHub’s API. +- 🔧 **Tool Calling** - LLM can call workspace functions (file reading, git operations, search) with manual approval or automatic execution for trusted tools +- 🔒 **Privacy First** - Only shares what you explicitly request - no background data collection +- 📝 **Interactive Chat** - Interactive UI with completion, diffs, and quickfix integration +- 🎯 **Smart Prompts** - Composable templates and sticky prompts for consistent context +- ⚡ **Token Efficient** - Resource replacement prevents duplicate context, history management via tiktoken counting +- 🔗 **Scriptable** - Comprehensive Lua API for automation and headless mode operation +- 🔌 **Extensible** - Custom functions and providers , plus integrations like mcphub.nvim -============================================================================== -1. Copilot Chat for Neovim *CopilotChat-copilot-chat-for-neovim* - - - - -|CopilotChat-| +============================================================================== +1. Installation *CopilotChat-installation* - [!NOTE] A new command, `CopilotChatBuffer` has been added. It allows you to - chat with Copilot using the entire content of the buffer. - [!NOTE] A new command, `CopilotChatInPlace` has been introduced. It functions - like the ChatGPT plugin. Please run ":UpdateRemotePlugins" command and restart - Neovim before starting a chat with Copilot. To stay updated on our roadmap, - please join our Discord community. +REQUIREMENTS *CopilotChat-requirements* -PREREQUISITES *CopilotChat-copilot-chat-for-neovim-prerequisites* +- Neovim 0.10.0+ +- curl 8.0.0+ +- Copilot chat in the IDE enabled in GitHub settings +- plenary.nvim -Ensure you have the following installed: -- **Python 3.10 or later**. -- **Python3 provider**: You can check if it’s enabled by running `:echo has('python3')` in Neovim. If it returns `1`, then the Python3 provider is enabled. -- **rplugin**: This plugin uses the |remote plugin| system of Neovim. Make sure you have it enabled. + [!WARNING] For Neovim < 0.11.0, add `noinsert` or `noselect` to your + `completeopt` otherwise chat autocompletion will not work. For best + autocompletion experience, also add `popup` to your `completeopt` (even on + Neovim 0.11.0+). +OPTIONAL DEPENDENCIES *CopilotChat-optional-dependencies* -AUTHENTICATION *CopilotChat-copilot-chat-for-neovim-authentication* +- tiktoken_core - For accurate token counting + - Arch Linux: Install `luajit-tiktoken-bin` or `lua51-tiktoken-bin` from AUR + - Via luarocks: `sudo luarocks install --lua-version 5.1 tiktoken_core` + - Manual: Download from lua-tiktoken releases and save as `tiktoken_core.so` in your Lua path +- git - For git diff context features +- ripgrep - For improved search performance +- lynx - For improved URL context features -It will prompt you with instructions on your first start.

Read the provided relevant workspace information (code excerpts, file names, and symbols) to understand the user's workspace. - -2. Consider how to answer the user's prompt based on the provided information and your specialized coding knowledge. Always assume that the user is asking about the code in their workspace instead of asking a general programming question. Prefer using variables, functions, types, and classes from the workspace over those from the standard library. - -3. Generate a response that clearly and accurately answers the user's question. In your response, add fully qualified links for referenced symbols (example: [`namespace.VariableName`](path/to/file.ts)) and links for files (example: [path/to/file](path/to/file.ts)) so that the user can open them.
