[Showcase] codex.nvim: Lightweight Neovim Plugin for Codex CLI

Hi Codex team and community!

I'm excited to share a new lightweight Neovim plugin: codex.nvim.

What is codex.nvim?

• Seamless Neovim integration for the OpenAI Codex CLI
• Opens the Codex TUI in a terminal split for fast AI coding workflows
• Minimal, easy to configure, inspired by base.nvim and claudecode.nvim
• Supports Snacks integration, flexible split direction/size, project root detection, and more

Features:

• Neovim split terminal for Codex TUI
• Quick keymaps to open/toggle Codex
• Flexible terminal sizing (fraction/absolute)
• Native or snacks.nvim terminal providers
• Logging, project-aware workflows, and more

Quickstart:

require('codex').setup()
vim.keymap.set('n', '<leader>co', function() require('codex').open() end)
vim.keymap.set('n', '<leader>ct', function() require('codex').toggle() end)

Why codex.nvim?
If you want a fast, minimal, and configurable way to use Codex right inside Neovim, this plugin is for you. Feedback and contributions are very welcome!
