This plugin allows you to chat with github copilot.

This plugin is unofficial and based on Copilot Chat for neovim repository: https://github.com/CopilotC-Nvim/CopilotChat.nvim

Feel free to contribute (check the Todo list ), report issues or discuss new features.

(use-package copilot-chat
  :straight (:host github :repo "chep/copilot-chat.el" :files ("*.el"))
  :after request)

Clone repository and eval files in emacs.

You will need a github acccount with access to copilot API. When sending the first prompt, you will need to authenticate to github. Follow instructions and everything will be fine.

If copilot-chat-use-curl is set to t (default), copilot-chat will use curl program for https requests. The path can be set in copilot-chat-curl-program. You can switch back to request library by setting copilot-chat-use-curl to nil.

With curl, answers will be written token by token.
With request library, the text is written when all data is read and this can be long.

Several frontends are available. You can select your favorite by setting the copilot-chat-frontend variable to 'markdown or 'org.

You can also use 'shell-maker if you want ( https://github.com/xenodium/chatgpt-shell ).

(use-package copilot-chat
  :straight (:host github :repo "chep/copilot-chat.el" :files ("*.el"))
  :custom
  (copilot-chat-frontend 'shell-maker)
  :config
  (require 'copilot-chat-shell-maker)
  (push '(shell-maker . copilot-chat-shell-maker-init) copilot-chat-frontend-list))
