should the project/package name be `prometheus-client` rather than `prometheus_client`

Hey.

I stumbled over the question what to use when one specifies the Prometheus Client as a dependency= in pyproject.toml?

• you guys seem to use prometheus_client (underscore)
  https://github.com/prometheus/client_python/blob/46eae7bae88f76951f7246d9f359f2dd5eeff110/pyproject.toml#L6C9-L6C26
• PyPi seems to use prometheus-client (i.e. when one enters the URL with underscore, it forwards to the one with hyphen)

The actual package build/installation seems to work with both names.

For me the whole Python packaging standard are like big mess ^^... but, if I understand correctly the following possibly means:

The name should be lowercased with all runs of the characters ., -, or _ replaced with a single - character.

that the name should be with hypen.

So maybe that should be changed in pyproject.toml and many other places like e.g.:

• https://github.com/prometheus/client_python/blob/46eae7bae88f76951f7246d9f359f2dd5eeff110/README.md?plain=1#L8
• https://github.com/prometheus/client_python/blob/46eae7bae88f76951f7246d9f359f2dd5eeff110/pyproject.toml#L49
• https://github.com/prometheus/client_python/blob/46eae7bae88f76951f7246d9f359f2dd5eeff110/README.md?plain=1#L20

and perhaps more in tox.ini and mypy.ini?

Cheers,
Chris.

Start with the referenced entries in pyproject.toml and README.md, then search tox.ini, mypy.ini, and the repository for project-name references. Check the Python packaging name-normalization guidance before deciding which spelling should be canonical. Done means the chosen name is used consistently and the package still builds and installs successfully.
