Línea de trabajo

Start with backend/arena/runner/harness.js, especially pythonProgram and javascriptProgram, then inspect LANGUAGES and starterCode; review the problem type list and per-problem runnableLanguages support. Add the C# driver and typed starter code for supported problems, wire Judge0 ID 51, and add coverage under backend/tests/. Verify against real Judge0, run npm test, and confirm node scripts/check-boundary.js passes.

Descripción

enhancement help wanted

A common interview language. System.Text.Json handles input and output, and value tuples such as (string, int) cover every tuple type, so no problems should need to be left out.

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 of pythonProgram / javascriptProgram. The marker nonce must stay per-run.
  • LANGUAGES in the same file: add { label, judge0Id }.
  • starterCode(problem, language): typed starter code built from problem.function (name, params[].type, returns).
  • backend/arena/runner/executors.js: localExecutor only knows node and python3; 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: C# (Mono) 51; 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.yml in the repo root runs one locally).
  • Tests in backend/tests/ covering the driver output and starter code; npm test stays green.
  • node scripts/check-boundary.js passes.
