How to configure repositories for index publishing

---

You can select the repository with which to upload using the -r/--repo option or by setting the HATCH_INDEX_REPO environment variable.

Rather than specifying the full URL of a repository, you can use a named repository from a publish.index.repos table defined in Hatch's config file:

[publish.index.repos.private]
url = "..."
...

The following repository names are reserved by Hatch and cannot be overridden:

Name	Repository
main	https://upload.pypi.org/legacy/
test	https://test.pypi.org/legacy/

The main repository is used by default.
