LeetCode Toolkit

https://github.com/eclipher/leetcode-toolkit

Feature

This userscript enhances the LeetCode problem page with various tweaking and additions. It supports both the US version of LeetCode.com, and the China version.

  • At the top of problem description, these buttons are added:

    • Copy Title
    • Copy Description: Copies the problem description in Markdown format, making it easy to paste into your notes or documentation.
    • Download as Jupyter Notebook: Bundles the title, description in Markdown, and the current content in the code editor into a single .ipynb file.
    • Find Editorial(*): Open a screenshot of the Editorial for the current problem, if it exists in the Leetcode Screenshotter repo.

  • Quality-of-life adjustments:

    • Format On Save: Automatically format code when pressing Ctrl + S.
    • Unlock IntelliSense: Enjoy autocompletion and hover suggestions without paying for premium.

  • Experimental:

    • Download Editorial(*): You can find this command under your userscript manager menu (right click context menu or extension icon on browser toolbar). If you have access to an editorial, click on the command and the editorial will be saved as an .md file. This feature currently has limitations:
      • Code in editorial will be saved as a link to a Leetcode playground. In addition to playground link, the actual code are now scraped too.
      • Math expressions will be displayed as plain text Math expressions are now saved in html format, and compatible viewer such as VS Code can render them correctly.
      • Videos will be skipped.
      • Slides will not be saved.

(*) Editorial-related features are for US site only, as China site do not seem to lock their editorials behind premium.

About Jupyter Notebook

Jupyter Notebook is an open-source web application that allows you to create and share documents that contain live code, equations, visualizations, and narrative text.

This userscript helps you transfer LeetCode problems into a Jupyter Notebook document, so you can read the problem, write and run the solution, add additional notes, all at one place on your local machine.

You can open .ipynb notebooks with clients such as VS Code. By default it supports Python, but kernels for many other languages are available too.

Installation

To use this userscript, you'll need a userscript manager like Tampermonkey (available for Chrome, Firefox, and other browsers).

  1. Install Tampermonkey or a similar userscript manager for your browser.
  2. Download and install the userscript.
  3. Visit a LeetCode problem page, and you should see the new features added by the script.
