Cursor's xaver.clang-format extension does not support CUDA C++

Phenomenon

The default formatter for CUDA C++ in VS Code or Cursor is ms-vscode.cpptools. However, it produces different formatting results from the Emacs clang-format package.

However, if I set the formatter to xaver.clang-format, Cursor prompts me that xaver.clang-format does not support CUDA C++.

Solution

Still use the formatter ms-vscode.cpptools, but should additionally assign the path to clang-format to the setting C_Cpp.clang_format_path.

Related settings in $HOME/.config/Cursor/User/settings.json are below.

"[cpp]": {
      "editor.defaultFormatter": "xaver.clang-format"
  },
"files.associations": {
  "*.hcu": "cuda-cpp",
  "*.h": "cpp"
},
"[cuda-cpp]": {
  "editor.defaultFormatter": "ms-vscode.cpptools"
},
"editor.defaultFormatter": "xaver.clang-format",
"editor.formatOnSave": true,
"C_Cpp.clang_format_path": "/usr/bin/clang-format",
"C_Cpp.clang_format_style": "file",
"clang-format.executable": "/usr/bin/clang-format",

Now I can edit source code in Emacs and Cursor at the same time. The reason for why I use them both is: Cursor has the advantage of code structure overview, visualization and navigation diffs, while Emacs is more efficient for code modification, pattern searching via ripgrep.
