cp.nvim

Fast, minimal competitive programming environment for Neovim

Scrape problems, run tests, and debug solutions across multiple platforms with zero configuration.

Disclaimer: cp.nvim webs crapes data from competitive programming platforms - use at your own risk.

https://github.com/user-attachments/assets/cb142535-fba0-4280-8f11-66ad1ca50ca9

Features

  • Multi-platform support: AtCoder, Codeforces, CSES with consistent interface
  • Automatic problem setup: Scrape test cases and metadata in seconds
  • Rich test output: ANSI color support for compiler errors and program output
  • Language agnostic: Works with any compiled language
  • Template integration: Contest-specific snippets via LuaSnip
  • Diff viewer: Compare expected vs actual output with precision

Optional Dependencies

  • uv for problem scraping
  • LuaSnip for templates

Quick Start

cp.nvim follows a simple principle: solve locally, submit remotely.

Basic Usage

  1. Find a problem on the judge website

  2. Set up locally with :CP <platform> <contest> <problem>

    :CP codeforces 1848 A

  3. Code and test with instant feedback and rich diffs

    :CP run

  4. Navigate between problems

    :CP next
:CP prev

  5. Submit on the original website

Documentation

:help cp.nvim

See my config for a relatively advanced setup.
