Copilot Chat plugin for Neovim

Description

copilot-chat.lua is a simple Neovim plugin for interacting with Copilot Chat.

Status

Work in progress.

Installation

The plugin depends on plenary.nvim and requires curl to be installed. A Copilot plugin, either copilot.lua or copilot.vim, needs to be authenticated.

Lazy.nvim

return {
  "somnam/copilot-chat.lua",
  cmd = "CC",
  cond = function()
    return vim.fn.executable("curl") == 1
  end,
  dependencies = {
    { "nvim-lua/plenary.nvim" },
  },
}

Usage

To use the plugin, follow these steps:

• :CC <action>? <input>? — Create a new chat buffer with optional input. Uses the default chat action if none is provided.

Actions

Available Chat actions:

• default[!] - provide general suggestions or recommendations based on the input or context of the code
• explain[!] - learn more about the concepts or techniques used in the selected code
• refactor[!] - improve the structure, readability, or performance of the code
• fix[!] - identify and resolve bugs or problems in the code
• tests[!] - request suggestions for writing tests for code
• new - request suggestions for creating a new project
• workspace - help with tasks such as organizing files, configuring settings, or integrating external tools
• commit - generate commit messages

The current visual selection serves as context when executing the command. Certain actions can be appended with an ! to use the current file as the command context instead of visual selection.

Chat buffer

After running the command a new markdown buffer is populated with the chat contents. To continue the chat write a response in the buffer and run the CC command without any arguments.

Examples

Explain

Use visual mode to select a block of code and run :CC explain.

Tests

Open a file and run :CC tests! to have unit tests generated for the file contents.
