Referenced yml files are not copied

[guoquan]

My (local) yml spec file references to another (local) yml in the definition. However, the extension seems not able to detect the reference and copy them.
For example:

a.yml

# ...
components:
  schemas:
    user:
      $ref: 'b.yml#/components/schemas/user'
# ...

b.yml

# ...
components:
  schemas:
    user:
      type: object
# ...

and in conf.py

# ...
redoc = [
    {
        "name": "My API",
        "page": "path/to/a",
        "spec": "path/to/a.yml",
    },
]
# ...

The extension detects "path/to/a.yml" and copy it to _build/html/_spec. However, b.yml is not copied and the page just failed to load.

Could there be a way to list the yml files I want to use for rendering the docs page, and the extension will copy and prepare them (and manipulate the paths) for me?

With tools like https://github.com/wework/speccy we can allow a list of spec and merge them into one so that the current process is good.

If anyone is interested, I came up with a workaround merging the files at the build time in conf.py with prance.
(speccy ran into an infinite loop with my spec file)

However, it would be good if supported in the extension.

# conf.py

def resolve(path: str, to: str = None):
    import logging
    import subprocess
    import tempfile
    from os.path import basename, join

    if to is None:
        basenames = basename(path).rsplit(".", maxsplit=2)
        assert len(basenames) == 2
        # to = to or f"{path_names[0]}.resolved.{path_names[1]}"
        to = f"{join(tempfile.gettempdir(),basenames[0])}.resolved.{basenames[1]}"

    subprocess.run(["prance", "compile", path, to])
    logging.getLogger(__name__).info(f"Resolved {path} to {to}")

    return to

redoc = [
    {
        "name": "My API",
        "page": "my/api/index",
        "spec": resolve("my/api/index.yml"),
        "embed": True,
    },
]
