Installation
============
pip install b3j0f.utils
Features
========
This library provides a set of generic tools in order to ease development of projects in python >= 2.6.
Provided tools are:
- chaining: chain object methods calls in a dedicated Chaining object. Such method calls return the Chaining object itself, allowing multiple calls to object methods to be invoked in a concise statement.
- 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 (transform dynamic variable to static variable in function, provide safe eval/exec functions).
- proxy: create proxy (from design pattern) objects from a routine or an object which respects the signature and description of the proxified element.
- ut: improve unit tests.
- version: ease compatibility between python version (from 2.x to 3.x).
Examples
========
Chaining
--------
>>> # add characters to a string in one line
>>> from b3j0f.utils.chaining import Chaining, ListChaining
>>> c = Chaining("te").__iadd__("s").__iadd__("t")
>>> # display content of Chaining
>>> c._
test
>>> # call several strings operations on several strings and get operation results in one line
>>> ListChaining("Test", "Example").upper().lower()[:]
[["TEST", "EXAMPLE"], ["test", "example"]]
Iterable
--------
>>> from b3j0f.utils.iterable import is_iterable, first, last, itemat, sliceit, hashiter
>>> is_iterable(1)
False
>>> is_iterable('aze')
True
>>> is_iterable('aze', exclude=str)
False
>>> from b3j0f.utils.version import OrderedDict
>>> od = OrderedDict((('1', 2), ('3', 4), ('5', 6)))
>>> first(od)
'1'
>>> first({}, default='test')
'test'
>>> last(od)
'5'
>>> last('', default='test')
'test'
>>> itemat(od, -1)
'5'
>>> itemat(od, 1)
'3'
>>> sliceit(od, -2, -1)
['3']
>>> hashiter([1, 2])
8
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})
>>> assert get_properties(min) == {'test': True}
>>> del_properties(min)
>>> assert get_properties(min) is None
>>> from b3j0f.utils.property import addproperties
>>> def before(self, value, name): # define a before setter
>>> self.before = value if hasattr(self, 'after') else None
>>> def after(self, value, name):
>>> self.after = value + 2 # define a after setter
>>> @addproperties(['test'], bfset=before, afset=after) # add python properties
>>> class Test(object):
>>> pass
>>> assert isinstance(Test.test, property) # assert property is bound
>>> test = Test()
>>> test.test = 2
>>> assert test.update is None # assert before setter
>>> assert test.test == test._test == 2 # assert default setter
>>> assert test.after == 4
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
Proxy
-----
>>> from b3j0f.utils.proxy import get_proxy, proxified_elt
>>> l = lambda: 2
>>> proxy = get_proxy(l, lambda: 3)
>>> proxy()
3
>>> assert proxified_elt(proxy) is l
True
>>> proxified_elt(proxy)()
2
>>> proxy = get_proxy(l)
>>> proxy()
2
>>> assert proxy is not l
>>> assert proxified_elt(proxy) is l
Runtime
-------
>>> from b3j0f.utils.runtime import safe_eval
>>> try:
>>> safe_eval('open')
>>> except NameError:
>>> print('open does not exist')
open does not exist
Version
-------
>>> from b3j0f.utils.version import getcallargs
>>> # getcallargs is same function from python>2.7 for python2.6
>>> from b3j0f.utils.version import PY3, PY2, PY26, PY27
>>> # PY3 is True if python version is 3, etc.
UT
--
>>> from b3j0f.utils.ut import UTCase # class which inherits from unittest.TestCase
>>> UTCase.assertIs and True # all methods of python2/3 TestCase are implemented in the UTCase for python v>2.
True
Perspectives
============
- Cython implementation.
