A python package making it easy to drop a multi-module package from sys.modules

Project description

Installation

You can either download or clone this repo, or alternatively you can install this module using pip:

pip install blackout

Overview

Blackout is a small micro-module which makes it easier to completely forget packages. This is particularly useful when working with packages made up of multiple sub-modules.

And example might be:

/site-packages/foo/__init__.py
/site-packages/foo/bar.py

If bar.py has a function called foo() within it, and we change that function then it is not enough to reload foo, we must specifically reload foo as well as foo.bar.

When working with packages with any modules this can be time consuming and problematic - particularly when developing within a host which is persistent.

Blackout helps, because we can unload the package in its entirety in a single line using:

```blackout.drop('foo')```

This will remove any hold to foo as well as any submodules of foo. In this case we can simply call import foo again, knowing that everything within that package is being loaded fresh.

Compatability

This has been tested under Python 2.7.13 and Python 3.6.6 under both Windows and Ubuntu.
