Relevant Rules

pip_parse

Description

Related to #414.

In the old pip_install the generated repository was of the form

<repo>/pypi__<sanitized-name>/...

with pip_parse it's

<repo>_pypi__<sanitized-name>/...

I'd like to be able to customize the pypi__ prefix (in particular making it "", so that the repositories are of the form <repo>_<sanitized-name>, which is easy to remember and type if you're say invoking an aspect against a requirement.) For pip_install it's not straightforward because of #414 (comment), but for pip_parse there's no problem.

Describe the solution you'd like

Make the default prefix here:

https://github.com/bazelbuild/rules_python/blob/master/python/pip_install/extract_wheels/lib/bazel.py#L107

configurable by an argument to the rule. Happy to make this change if deemed acceptable.

Describe alternatives you've considered

Live with the status quo.
