This is documented but, for some reason, I always forget it.

Visual Studio Code is awesome and, in particular when debugging, it’s useful to set environment variables.

I write a lot of Google Cloud code and so I’m frequently wanting:

launch.json:

{
    "version": "0.2.0",
    "configurations": [
        {
            ...
            "env": {
                "GOOGLE_APPLICATION_CREDENTIALS": "...",
                "PROJECT": "...",
            }
        }
    ]
}

And, through a combo of forgetfulness and laziness, I tend to duplicate the values from the host environment as strings in these files.
