Publish a repository using credentials from .pypirc

[lmmx]

I can't tell if this is supposed to be implemented already, namely because there's mention of a variable $(PYPIRC_PATH) in #2141:

• Allow specifying username and password in URL #2141 (comment)

  - script: |
      pdm publish --repository $(PYPIRC_PATH)
    displayName: 'Build package and publish'

I think though that it's intended to indicate a URL. I initially saw that and thought I was meant to supply ~/.pypirc (which is where twine gets my token from when I publish Python packages typically).

I dug into what actually goes on and ended up breakpointing at pdm/project/config.py(447)get_repository_config().

The .pypirc file looks like this:

[pypi]
  username = __token__
  password = pypi-XXXXXXXXX...

Can this be used to generate the repository URL with all the necessary config instead of requiring it be passed in? Or does this feature already exist somewhere I missed?

More simply (if the --repository flag is not the place for this), the feature request could also be phrased as "autodetect username and password from .pypirc when running pdm publish". In this case the solution was to just manually copy the username (__token__) and password from this file and supply them to --publish.

The value of --repository can be either a upload URL or the name of a configured repository in pdm config. Yeah, PDM has its own config file and won't read .pypirc.
