调研方向
Start with backend/arena/runner/harness.js, comparing pythonProgram and javascriptProgram, then inspect LANGUAGES, starterCode, and the relevant tests in backend/tests/. Implement a C++ driver and typed starter code for supported problem types, wire up the Judge0 language id, and validate correct and incorrect solutions across difficulty levels and types using a real Judge0. Done means npm test and node scripts/check-boundary.js pass.

描述
Popular for competitive programming. C++ has no built-in JSON reader, so the driver needs a small parser for the input format above. std::pair / std::tuple cover the tuple types.
CodeArena runs player code in Python, JavaScript and TypeScript. Adding a language is self-contained and a great way to get into the codebase.
Where the code lives
backend/arena/runner/harness.js: one small driver per language. The driver reads{"tests":[{"args":[...]}]}as JSON on stdin, calls the player's function once per test, and prints the per-run marker line followed by a JSON array of{ ok, value }/{ ok, error }. Copy the shape ofpythonProgram/javascriptProgram. The marker nonce must stay per-run.LANGUAGESin the same file: add{ label, judge0Id }.starterCode(problem, language): typed starter code built fromproblem.function(name,params[].type,returns).backend/arena/runner/executors.js:localExecutoronly knowsnodeandpython3; add your compiler for local development if you like (it is never used in production).
Types the 45 problems use
integer, integer[], integer[][], number[], string, string[], boolean, and tuples: [integer, integer], [integer, integer][], [integer, integer, integer][], [string, integer][], [string, string, string][], [integer, integer, string].
Statically typed languages need a mapping for each of these. If a mixed tuple such as [string, integer] has no clean equivalent in your language, it is fine to leave that problem out for your language rather than force an awkward type: the loader supports per-problem languages via runnableLanguages.
Definition of done
- Driver plus typed starter code for every problem your language supports.
- Judge0 language id wired up (Judge0 CE: Java 62, C++ 54, Go 60; confirm on your Judge0 instance).
- Proof: correct solutions pass and wrong ones fail on a spread of problems (easy, medium, hard, and every type above) against a real Judge0 (
docker-compose.judge0.ymlin the repo root runs one locally). - Tests in
backend/tests/covering the driver output and starter code;npm teststays green. node scripts/check-boundary.jspasses.
