Leetgo

中文 | English

leetgo is a command line tool that generates skeleton code for LeetCode questions in many languages. You can run and debug test cases locally with your favorite IDE. Then you can submit your code to LeetCode directly.

leetgo supports generating contest questions as well.

LeetCode Support

Leetgo uses LeetCode's GraphQL API to get questions and submit solutions. You need to provide your LeetCode session ID to authenticate.

Currently only leetcode.cn is supported. leetcode.com is under development.

Configuration

Leetgo reads global configuration from ~/.config/leetgo/config.yaml and local configuration from leetgo.yaml in your project root, which are generated automatically when you run leetgo init. You can tweak the configuration to your liking.
