Quick Start

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

Basic Usage

  1. Find a contest or problem on the judge website

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

    :CP codeforces 1848

  3. Code and test with instant feedback

    :CP run        " Quick verdict summary in splits
:CP panel      " Detailed analysis with diffs

  4. Navigate between problems

    :CP next
:CP prev
:CP e1

  5. Submit on the original website

Documentation

:help cp.nvim

See my config for a relatively advanced setup.
