  • Integrated build, run, and debug commands
  • Enhanced test viewer with individual test case management
  • LuaSnip integration for contest-specific snippets

Requirements

Philosophy

This plugin is highly tuned to my workflow and may not fit for you. Personally, I believe there are two aspects of a cp workflow:

  • local work (i.e. coding, running test cases)
  • site work (i.e. problem reading, submitting)

Namely, I do not like the idea of submitting problems locally - the experience will never quite offer what the remote does. Therefore, cp.nvim works as follows:

  1. Find a problem
  • Browse the remote and find it
  • Read it on the remote
  1. Set up your local environment with :CP ...
  • test cases and expected output automatically scraped
  • templates automatically configured
  1. Solve the problem locally
  • easy to run/debug
  • easy to diff actual vs. expected output
  1. Submit the problem (on the remote!)

TODO

  • fzf/telescope integration (whichever available)
  • autocomplete with --lang and --debug
  • finer-tuned problem limits (i.e. per-problem codeforces time, memory)
  • notify discord members
