Fix kernel configuration for xeus-cpp-lite

anutosh491 commented 2 days ago

This is the kernel.json file I see while building xeus-cpp-lite

{
  "display_name": "C++20",
  "env": {
      "PATH":"/Users/anutosh491/micromamba/envs/xeus-cpp/bin:/Users/anutosh491/.pixi/bin:/Users/anutosh491/miniconda3/bin:/opt/homebrew/bin:/opt/homebrew/sbin:/usr/local/bin:/System/Cryptexes/App/usr/bin:/usr/bin:/bin:/usr/sbin:/sbin:/var/run/com.apple.security.cryptexd/codex.system/bootstrap/usr/local/bin:/var/run/com.apple.security.cryptexd/codex.system/bootstrap/usr/bin:/var/run/com.apple.security.cryptexd/codex.system/bootstrap/usr/appleinternal/bin:/Users/anutosh491/micromamba/condabin:/Users/anutosh491/.pixi/bin:/Users/anutosh491/miniconda3/bin",
      "LD_LIBRARY_PATH":""
  },
  "argv": [
      "/Users/anutosh491/micromamba/envs/xeus-cpp/bin/xcpp",
      "-f",
      "{connection_file}",
      "-resource-dir", "/Users/anutosh491/micromamba/envs/xeus-cpp/lib/clang/19",
      "-I", "/Users/anutosh491/micromamba/envs/xeus-cpp/include",
      "-std=c++20"
  ],
  "language": "cpp",
  "metadata": {"debugger": false
  }
}

Most things are redundant (or can't be used in a wasm context) except 1) kernel display name 2) c++ version based on kernel name 3) language (cpp or c I guess) 4) debugger info

Things like env, resource dir and other include paths if any can't be put to use. There is no xcpp exectuable either (a wasm build would give us xcpp.js, xcpp.wasm, xcpp.data) and we just have an empty placeholder there.

We should be able to fetch the c++ version out of kernel.json and pass it here https://github.com/compiler-research/xeus-cpp/blob/859a1b956b8ebf137ed97b73af825063319d44eb/src/main_emscripten_kernel.cpp#L18-L23
