|
|
The idea here is that these formed a major chunk of InstallRequirement's size
|
so, moving them and support code dedicated to them outside of that class
|
helps creates for better understandability for the rest of the code.
|
|
These are meant to be used elsewhere within pip to create instances of
|
InstallRequirement.

First, it checks whether a provided path is an installable directory. If it

is, returns the path.
|
|
If false, check if the path is an archive file (such as a .whl).

The function checks if the path is a file. If false, if the path has

an @, it will treat it as a PEP 440 URL requirement and return the path.
