Emacs Copilot

Emacs Copilot is an Emacs package that uses the OpenAI API or Google Gemini to generate Emacs Lisp code and content based on given instructions. This package offers a convenient way to create code snippets or analyze text directly within Emacs.

Installation

Make sure the request and request-deferred packages are installed. Install them using M-x package-install RET request RET and M-x package-install RET request-deferred RET.
Add the emacs-copilot.el file to your Emacs load-path.
Add the following lines to your Emacs configuration:

(require 'emacs-copilot)

;; if you want to openai key 
(setq emacs-copilot-api-provider 'openai)
(setq emacs-copilot-openai-api-key "openai key")

;; if you want to use gemini
(setq emacs-copilot-api-provider 'google-gemini)
(setq emacs-copilot-google-gemini-api-key "")

Replace "your_openai_api_key" with your actual OpenAI API key.

Usage

Emacs Copilot provides the following interactive functions:

emacs-copilot: Generate Emacs Lisp code for a specified task.
emacs-copilot-generate: Generate content based on a given instruction.
emacs-copilot-process: Process the entire buffer or the selected region based on a provided instruction.

Generating Emacs Lisp code

To generate Emacs Lisp code for a specific task, call the emacs-copilot function:

M-x emacs-copilot

You will be prompted to enter the task description. The generated code will appear in a new buffer, and you will be asked if you want to evaluate it.

Generating content

To generate content based on a given instruction, call the emacs-copilot-generate function:

M-x emacs-copilot-generate

You will be prompted to enter the instruction. The generated content will appear in a new buffer called *GPT-Rewritten*.

Processing buffer or selected region

To process the entire buffer or the selected region based on a provided instruction, call the emacs-copilot-process function:

M-x emacs-copilot-process

You will be prompted to enter the instruction. The processed content will appear in a new buffer called *GPT-Rewritten*.

Customization

You can customize the emacs-copilot-api-key variable to set your OpenAI API key:

(setq emacs-copilot-api-key "your_openai_api_key")
