picage 0.2.2

Welcome to picage Documentation
picage provides a object style interface to handle Python package module / file structure. It gives you simple api to access:

a fullname, shortname of a python module
parent, sub packages and sub modules
recursively walk through all sub packages and sub modules

Note
Python is a Dyanamic Type Programming language, everything in Python
is an object, including python package and module.

Usage
>>> from picage import Package

>>> pip = Package("pip")
>>> pip
Package(name='pip', path='./venv/lib/python2.7/site-packages/pip')

>>> print(pip)
Package(
name='pip',
path='./venv/lib/python2.7/site-packages/pip',
sub_packages=['_vendor', 'commands', 'compat', 'models', 'operations', 'req', 'utils', 'vcs'],
sub_modules=['__main__', 'basecommand', 'baseparser', 'cmdoptions', 'download', 'exceptions', 'index', 'locations', 'pep425tags', 'status_codes', 'wheel'],
)

# visit sub packages
>>> for package_name, package in pip.sub_packages().items():
...

# visit sub modules
>>> for module_name, module in pip.sub_modules().items():
...

# walk through all sub packages modules
>>> for pkg, parent_pkg, sub_pkg_list, sub_module_list in pip.walk():
...

>>> commands = pip["commands"] # it's a sub package
>>> commands = Package("pip.commands") # or you can create it from dot notation

>>> commands.parent == pip # visit parent package
True
>>> pip.parent
None

>>> print(commands)
Package(
name='pip.commands',
path='./venv/lib/python2.7/site-packages/pip/commands',
sub_packages=[],
sub_modules=['check', 'completion', 'download', 'freeze', 'hash', 'help', 'install', 'list', 'search', 'show', 'uninstall', 'wheel'],
)

>>> install = commands["install"] # it's a module
>>> install = Module("pip.commands.install") # or you can create it from dot notation

# Display package structure
>>> pip.pprint()
