Path with spaces gets broken up at space

[patrikhuber]

Hi,

I've got a simple app with an --input argument that contains a path with a space. I'm using VS and launch.vs.json to launch this, so the args part of launch.vs.json looks like:

      "args": [
        "--input",
        "\"C:\\My - Long path\""
      ]

And I'm reading this into cxxopts with input_path = result["input"].as<std::filesystem::path>();.

The problem is that input_path only contains C:\\My.

I've tried it with and without the escaped quotes in launch.vs.json (i.e. with and without the extra \" but it didn't make any change. I can also confirm that argv[2] does confirm the whole path, i.e. argv[2] is a char* containing "C:\\My - Long path".

Seems cxxopts is parsing / breaking this up wrongly?

I suspect that because you have used std::filesystem::path it is getting put through the stringstream parser which is splitting it at the first space. If you make it a string then it should work. It should probably just work though, I'll see if I can work out a proper fix.
