Welcome to the fascinating world of theorem proving with LeanDojo! In this guide, we will explore how to utilize LeanDojo, a Python library designed for learning-based theorem provers in Lean, to enhance your programming experience and streamline your work. Let’s dive into the essentials that you need to get started!

Getting Started with LeanDojo

LeanDojo offers two main features:

• Extracting data (proof states, tactics, premises, etc.) from Lean repositories.
• Interacting with Lean programmatically.

This current version is compatible with Lean 4 v4.3.0-rc2 or later, and using the latest version is strongly recommended for the best features and performance.

Requirements

Before you can install LeanDojo, make sure you meet the following requirements:

• Platforms supported: Linux, Windows WSL, and macOS.
• Git >= 2.25
• Python >= 3.9 and <= 3.12
• wget
• elan
• Generate a GitHub personal access token and set the environment variable GITHUB_ACCESS_TOKEN to it.

Installation of LeanDojo

Installing LeanDojo is a breeze. You have two options:

1. Install via pip from PyPI:

pip install lean-dojo

2. Alternatively, you can install it locally from the Git repository:

pip install .

Understanding the Code: An Analogy

Imagine LeanDojo as a Swiss Army Knife for theorem proving in programming. Each tool in this knife represents a functionality of LeanDojo. For instance:

• Extracting proof states and tactics can be seen as using the knife blade – it’s essential for cutting through complex problems.
• Interacting programmatically is like using the screwdriver – it allows you to customize and manipulate various components.

Just as you can rely on a Swiss Army Knife to have all the tools at your disposal for any challenge, LeanDojo equips you with the necessary features to tackle theorem proving efficiently!
