Package name normalisation is flip-flopping

[hynek]

Some packages like Jinja2 have multiple valid ways to write them. Depending on what you do, they flip-flop between them.

Describe your environment

1. OS Type macOS
2. Python version: $ python -V 3.6.4
3. Pipenv version: $ pipenv --version 9.0.1 and current master

Expected result

Package names in Pipfile stay constant.

Actual result

When installing Jinja2 becomes lowercase, when uninstalling any other package, it becomes uppercase.

Steps to replicate

$ pipenv install --verbose jinja2

Notice the capital “J”. As you can imagine, that’s rather annoying when checking in changes. :)

I tracked it down to this change bb0719f. We used to verify casing when an install or uninstall action was performed. The install portion was short circuited so everything has been written as our pep423 format for normalization. When uninstall is run, it still writes names to the packages as the author intended.

We need to choose one format or the other and then change this to work with it.

+1 for using the package's canonical form.

While the lock file should definitely use normalised forms, Pipfile is a little trickier as:

• if the user edits Pipfile manually, pipenv should preserve their original spelling
• if pipenv install edits Pipfile, then it's reasonable to normalise the name before making the edit

So I think the key issue here is that neither pipenv install nor pipenv uninstall should be altering any Pipfile entries that aren't affected by the current command.
