how to create a lsp client to connect to vscode-cpptools?

[zhangzheyu2simple]

I am trying to add some additional code formatting to the cpp file, so I need the AST of the current cpp file.
So, is it possible to create an lsp client to connect to vscode-cpptools and get the AST? If so, is there such a tutorial?

We don't provide an AST. Is the additional code formatting based on vcFormat or clang-format or is it some new formatting? You could try using the clang AST.
