ℹ️ About

Lexy is a lightweight Python CLI that brings tutorials from Learn X in Y Minutes straight into your terminal. It is designed for quick lookup, learning, and reference without breaking your workflow.

Lexy keeps a local cache of the documentation so you can browse content offline, preview it with syntax highlighting through bat, and search available languages with fzf.

Full documentation is available at antoniorodr.github.io/lexy.

✨ Features

  • Read Learn X in Y Minutes tutorials directly from the terminal
  • Browse cached documentation offline after the first fetch
  • Preview syntax-highlighted content with bat
  • Search available languages with fzf
  • Refresh the local cache on demand with lexy update
  • Check when the cache was last updated with lexy modified
  • Customize the fzf layout and colors through config.toml

🛠️ Technologies

The project is built with:

📋 Requirements

Before starting, make sure the required tools and dependencies are installed on your machine:

python3.13 --version
fzf --version
bat --version

Lexy requires Python 3.13 or newer, plus fzf for searching and bat for syntax-highlighted previews.

On some Linux distributions, installing bat with apt provides the executable as batcat instead of bat. In that case, follow the official bat instructions to create the required symlink, since a shell alias is not visible to the Python subprocess Lexy uses.

📦 Installation

Manual installation

git clone https://github.com/antoniorodr/lexy
cd lexy
pip install .

Homebrew installation

brew tap antoniorodr/lexy
brew install antoniorodr/lexy/lexy

Installation with uv

uv tool install git+https://github.com/antoniorodr/lexy

AUR installation

🚀 Getting Started

Once installed, try the core commands:

lexy list
lexy python
lexy update
lexy modified

Use lexy list to browse available languages, pass a language name like lexy python to open a tutorial, use lexy update to refresh the local cache, and lexy modified to check when the cache was last updated.

Lexy stores its local documentation cache and configuration in $HOME/.config/lexy. The cache is created automatically on first run and refreshed automatically every 60 days.

If you want to customize the fzf interface, create a config.toml file in the Lexy config directory and override only the values you want to change.

For full usage details and theming examples, see the documentation site.
