Using a different package index

[cnpryer]

Summary

The solution for #482 was to allow (--) args to be passed to pip (the installer). Currently if a package index url is passed to pip it isn't persisted anywhere. So the user will have to know to use that package index url to reproduce the environment.

Motivation

Until better environment reproducibility can be implemented, there needs to be a way to reproduce installs that pass --index-url to pip. --index-url will always be configuration a future Huak will support, so a form of this can be added sooner rather than later.

Requirements

• Support --index-url in CLI
• If --index-url is used then packages added from that repository should be persisted with that information
• Allow for future package installer implementations (pip-agnostic)
• Securely use credentials for a package index

Questions

• If more than one package index is used per-project how are dependencies managed between them?
• Should --no-dependencies be implemented prior to this?
• Should this be persisted to pyproject.toml or entered to Huak's home directory?

Details

Per-project package index configuration

In the project's pyproject.toml file:

# ...

[tool.huak.package-index."my-index"]
url = "url to index"
dependencies = [
    "some-package",
]

Package index credentials management

In Huak's credentials.toml located in Huak's home directory:

[package-index."my-index"]
token = "encrypted authentication token"
