Configuration

Github

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.

Backend

copilot-chat-backend can be set to 'curl (default) or 'request.

With curl, answers will be written token by token. Curl path can be set with copilot-chat-curl-program variable.
With request library, the text is written when all data is read and this can be long.

Frontend

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"))
  :after (request shell-maker)
  :custom
  (copilot-chat-frontend 'shell-maker)
  :config
  (require 'copilot-chat-shell-maker)
  (push '(shell-maker . copilot-chat-shell-maker-init) copilot-chat-frontend-list)
  (copilot-chat-shell-maker-init))

Try them and choose wisely.
