This directory exists to enable certain VSCode extensions to work on multi-root VSCode workspaces.

For example, the Ruff VSCode extension requires a single virtual environment to run Ruff in for the entire workspace. This directory contains that virtual environment.

To set up the virtual environment, run the following command:

make install

Or just run make install from the root of the repository.

The workspace needs this directory to be added as a root.

{
    "folders": [
        ...
        {
            "path": ".multi-root-tools"
        },
        ...
    ]
}

And for ruff, it needs to be specified as the interpreter:

{
  "settings": {
    "ruff.interpreter": "${workspaceFolder:.multi-root-tools}/.venv"
  }
}
