tom-doerr / zsh_codex

This is a ZSH plugin that enables you to use OpenAI's Codex AI in the command line.

⌨️ 🦾 Zsh Codex

AI in the command line.

You just need to write a comment or variable name and the AI will write the corresponding code.

What is it?

This is a ZSH plugin that enables you to use AI powered code completion in the command line. It now supports both OpenAI's Codex and Google's Generative AI (Gemini). OpenAI Codex is the AI that also powers GitHub Copilot, while Gemini is Google's advanced language model.

How do I install it?

Manual Installation

1. Install the OpenAI package or the Google package.

pip3 install openai

or

pip3 install google-generativeai

2. Download the ZSH plugin.

git clone https://github.com/tom-doerr/zsh_codex.git ~/.oh-my-zsh/custom/plugins/zsh_codex 

3. Add the following to your .zshrc file.

Using oh-my-zsh:

    plugins=(zsh_codex)
    bindkey '^X' create_completion

Without oh-my-zsh:

    # in your/custom/path you need to have a "plugins" folder and in there you clone the repository as zsh_codex
    export ZSH_CUSTOM="your/custom/path"
    source "$ZSH_CUSTOM/plugins/zsh_codex/zsh_codex.plugin.zsh"
    bindkey '^X' create_completion

4. Create a file called openaiapirc in ~/.config with your SECRET_KEY.

[openai]
secret_key = ...

or Create a file called geminiapirc in ~/.config with your SECRET_KEY.

[gemini]
api_key = ...

You can also optionally specify: organization, base_url, model and temperature.

5. Set the LLM which you are going to use (you can choose between openai and gemini).

nano ~/.oh-my-zsh/custom/plugins/zsh_codex/zsh_codex.plugin.zsh

Set the api variable to openai or gemini.

6. Run zsh, start typing and complete it using ^X!

7. If you use virtual environments you can set ZSH_CODEX_PYTHON to python executable where openai or google-generativeai is installed. e.g. for miniconda you can use:

export ZSH_CODEX_PYTHON="$HOME/miniconda3/bin/python"

Troubleshooting

Unhandled ZLE widget 'create_completion'

zsh-syntax-highlighting: unhandled ZLE widget 'create_completion'
zsh-syntax-highlighting: (This is sometimes caused by doing `bindkey <keys> create_completion` without creating the 'create_completion' widget with `zle -N` or `zle -C`.)

Add the line

zle -N create_completion

before you call bindkey but after loading the plugin (plugins=(zsh_codex)).

Already exists and is not an empty directory

fatal: destination path '~.oh-my-zsh/custom/plugins'

Try to download the ZSH plugin again.

git clone https://github.com/tom-doerr/zsh_codex.git ~/.oh-my-zsh/custom/plugins/zsh_codex
