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

Set up a Codeforces problem with contest ID 1848:

:CP codeforces 1848 A

Navigate between problems:

:CP next
:CP prev

Run tests:

:CP run

Workflow

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

1. Find a problem on the judge website
2. Set up locally with :CP <platform> <contest> <problem>
3. Code and test with instant feedback and rich diffs
4. Submit on the original website
