This project is abandoned and scheduled for deletion.

After extensive development, the truth is clear: accuracy improvement in LLMs

is a myth. The idea that they can outperform general enterprise code production

is a bubble.

I don’t write open source for entertainment; I write to produce value.

Since this produces none, it's time to move on.

SuperCodex is a Neovim plugin that integrates, streamlines, and improves the use of local and cloud-based LLM's for coding purposes.

Setup

Note

This documentation does not cover how to host an LLM or how to obtain credentials for cloud-based LLM services. These steps are the responsibility of the user.

The plugin is built to work with an OpenAI-compatible API endpoint. It follows the standard OpenAI API specification for request/response formatting and authentication. As a result, any service that implements this interface should work seamlessly with the plugin.

In addition, users are responsible for selecting the LLM model. You should look for the latest and best-performing LLM, especially one that scores highly on coding and programming benchmarks, and that you can either run locally on your own hardware, or access through a cloud-based provider.

Below are some useful resources to help you explore, host, or discover local LLM's:

Create directory for Python virtual environments:

mkdir ~/.virtualenvs

Create virtual environment for NeoVim:

python -m venv ~/.virtualenvs/neovim

Activate the virtual environment:

source ~/.virtualenvs/neovim/bin/activate

Install pip libraries:

pip install pynvim pytest pytest-mock requests

Deactivate the virtual enviorment:

deactivate

💻 Local Version (for testing)

Create local plugins directory:

mkdir -p ~/.config/nvim/lua/local_plugins

Navigate to local plugins directory and Git clone this repository:

cd ~/.config/nvim/lua/local_plugins

git clone https://github.com/devbyte1328/supercodex.nvim.git

lazy.nvim:

{
  dir = vim.fn.stdpath("config") .. "/lua/local_plugins/supercodex.nvim",
  name = "supercodex",
  init = function()
    vim.g.python3_host_prog = vim.fn.expand("~/.virtualenvs/neovim/bin/python")
    vim.g.supercodex_api_key = "<API-GOES-HERE>"
    vim.g.supercodex_url = "<URL-ENDPOINT-GOES-HERE>"
    vim.g.supercodex_model = "<MODEL-GOES-HERE>"
    vim.keymap.set("n", "<leader>w", ":WindowInputPrompt<CR>", { noremap = true, silent = true, desc = "Open window input prompt" })
  end,
