Set of tools and utilities useful in python projects
Project description
Common tools useful to python projects.
Links
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.
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 >>> Chaining("te").__iadd__("s").__iadd__("t").content "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 >>> 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
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
Perspectives
Cython implementation.
