Installation

pip install b3j0f.utils

Description

This library provides a set of generic tools in order to ease development of projects in python >= 2.6.

Provided tools are:

• chaining: manage chaining of function call such as chaining execution in some javascript libraries like jquery or d3.

• iterable: tools in order to manage iterable elements.

• path: python object path resolver, from object to absolute/relative path or the inverse.

• property: (un)bind/find properties in reflective and oop concerns.

• reflect: tools which ease development with reflective concerns.

• runtime: ease runtime execution.

• ut: improve unit tests.

• version: ease compatibility between python version (from 2.x to 3.x).

Examples

Chaining

>>> from b3j0f.utils.chaining import Chaining, ListChaining
>>> Chaining("te") += "s" += "t" .content
"test"
>>> ListChaining("test", "example").upper()[-1]
["TEST", "EXAMPLE"]

Iterable

>>> from b3j0f.utils.iterable import is_iterable, first
>>> is_iterable(1)
False
>>> is_iterable("aze")
True
>>> is_iterable("aze", exclude=str)
False

>>> first("aze")
"a"
>>> first("", default="test")
"test"

Path

>>> from b3j0f.utils.path import lookup, getpath
>>> getpath(lookup)
"b3j0f.utils.path.lookup"
>>> getpath(lookup("b3j0f.utils.path.getpath")
"b3j0f.utils.path.getpath"

Property

>>> from b3j0f.utils.property import put_properties, get_properties, del_properties
>>> put_properties(min, {'test': True})
>>> get_properties(min)
{'test': True}
>>> del_properties(min)
>>> get_properties(min)
None

Reflect

>>> from b3j0f.utils.reflect import base_elts, is_inherited
>>> class BaseTest(object):
>>>     def test(self): pass
>>> class Test(BaseTest): pass
>>> class FinalTest(Test): pass
>>> base_elts(FinalTest().test, depth=1)[-1].im_class.__name__
Test
>>> base_elts(FinalTest().test)[-1].im_class.__name__
BaseTest

>>> is_inherited(FinalTest.test)
True
>>> is_inherited(BaseTest.test)
False
