What's this, another CPH/acmX/FastOlympicCoding/... clone?

Yep. I think it looks slightly better than any solution out there, though, and has maybe one more feature?

This was designed primarily for C++ (though you're able to run Java/Python/Rust, but they are mostly untested). It was developed on MacOS and hasn't been tested much on Windows/Linux.

If you think it's the best option out there for you and need a couple features/fixes, just open an issue on the Github. This is basically in alpha! I've made it public to source feedback and hope to substantially improve it.

Features

  • Integrates with clangd and CodeLLDB to provide compilation commands and debugging.
  • File I/O support
  • Bulk import test cases from directory
  • Competitive Companion integration
  • Stress testing
  • Custom interactor and checker support
  • Realtime I/O (in addition to test case inputs)
  • Debugging for all supported languages (if you have the right extensions installed)

Notes

  • To enable debugging & linting, install CodeLLDB and clangd
  • The run/debug options for stress tests run/debug the test generator for a random choice of i.
  • You probably need to fudge the compiler and arguments in the test editor or VSCode settings to fit your setup (currently it defaults g++, fallback clang)
  • Changing settings in the test editor will only change them for your current workspace (or globally if none)
  • Integrates with Competitive Companion, though uses the host port for Hightail (so you won't be able to use both of our integrations at once)
  • Debugging C++ uses SIGSTOP to halt the program while waiting for the debugger to attach (this was the simplest way). I'm not sure this works on Windows.
  • I feel incompetent because whenever I implement things it seems 10x more complicated than it needs to be, which creates so many failure modes. This thing is not super robust and I expect to discover many bugs.
    • If you ever want to laugh at some sad code, this is a goldmine!
