----------------------------------------------------
Independent programming idioms and utilities library
----------------------------------------------------
.. contents:: Table of Contents
:depth: 2
Overview
========
**acrilib** is a python library providing useful programming patterns and tools. **acrilib** started as Acrisel's internal idioms and utilities for programmers. The main key is that this library is completely independent. It does not use any external packages beside what provided by Python.
It includes:
1. programming idioms that are repeatedly used by programmers.
#. helpers functions for logging and other utilities.
We decided to contribute this library to Python community as a token of appreciation to
what this community enables us.
We hope that you will find this library useful and helpful as we find it.
If you have comments or insights, please don't hesitate to contact us at support@acrisel.com
Programming Idoms
=================
threaded
--------
decorator for methods that can be executed as a thread. RetriveAsycValue callable class used in the example below provide means to access results. One can provide their own callable to pass results.
example
~~~~~~~
.. code-block:: python
from acris import threaded, RetriveAsycValue
from time import sleep
class ThreadedExample(object):
@threaded
def proc(self, id_, num, stall):
s = num
while num > 0:
print("%s: %s" % (id_, s))
num -= 1
s += stall
sleep(stall)
print("%s: %s" % (id_, s))
return s
example output
~~~~~~~~~~~~~~
.. code-block:: python
print("starting workers")
te1 = ThreadedExample().proc('TE1', 3, 1)
te2 = ThreadedExample().proc('TE2', 3, 1)
print("collecting results")
te1_callback = RetriveAsycValue('te1')
te1.addCallback(te1_callback)
te2_callback = RetriveAsycValue('te2')
te2.addCallback(te2_callback)
print('joining t1')
te1.join()
print('joined t1')
print('%s callback result: %s' % (te1_callback.name, te1_callback.result))
result = te1.syncResult()
print('te1 syncResult : %s' %result)
result = te2.syncResult()
print('te2 syncResult : %s' % result)
print('%s callback result: %s' % (te2_callback.name, te2_callback.result))
will produce:
.. code-block:: python
starting workers
TE1: 3
TE2: 3
collecting results
joining t1
TE1: 4
TE2: 4
TE1: 5
TE2: 5
TE1: 6
TE2: 6
joined t1
te1 callback result: 6
te1 syncResult : 6
te2 syncResult : 6
te2 callback result: 6
Singleton and NamedSingleton
----------------------------
meta class that creates singleton footprint of classes inheriting from it.
Singleton example
~~~~~~~~~~~~~~~~~
.. code-block:: python
from acris import Singleton
class Sequence(Singleton):
step_id=0
def __call__(self):
step_id = self.step_id
self.step_id += 1
return step_id
example output
~~~~~~~~~~~~~~
.. code-block:: python
A=Sequence()
print('A', A())
print('A', A())
B=Sequence()
print('B', B())
will produce:
.. code-block:: python
A 0
A 1
B 2
NamedSingleton example
~~~~~~~~~~~~~~~~~~~~~~
.. code-block:: python
from acris import Singleton
class Sequence(NamedSingleton):
step_id = 0
def __init__(self, name=''):
self.name = name
def __call__(self,):
step_id = self.step_id
self.step_id += 1
return step_id
example output
~~~~~~~~~~~~~~
.. code-block:: python
A = Sequence('A')
print(A.name, A())
print(A.name, A())
B = Sequence('B')
print(B.name, B())
will produce:
.. code-block:: python
A 0
A 1
B 0
Sequence
--------
meta class to produce sequences. Sequence allows creating different sequences using name tags.
example
~~~~~~~
.. code-block:: python
from acris import Sequence
A = Sequence('A')
print('A', A())
print('A', A())
B = Sequence('B')
print('B', B())
A = Sequence('A')
print('A', A())
print('A', A())
B = Sequence('B')
print('B', B())
example output
~~~~~~~~~~~~~~
.. code-block:: python
A 0
A 1
B 0
A 2
A 3
B 1
TimedSizedRotatingHandler
-------------------------
TBD
Decorators
----------
Useful decorators for production and debug.
traced_method
~~~~~~~~~~~~~
logs entry and exit of function or method.
.. code-block :: python
from acris import traced_method
traced = traced_method(print, print_args=True, print_result=True)
class Oper(object):
def __init__(self, value):
self.value = value
def __repr__(self):
return str(self.value)
@traced
def mul(self, value):
self.value *= value
return self
@traced
def add(self, value):
self.value += value
return self
o=Oper(3)
print(o.add(2).mul(5).add(7).mul(8))
would result with the following output:
.. code-block :: python
[ add ][ entering][ args: (2) ][ kwargs: {} ][ trace_methods.py.Oper(39) ]
[ add ][ exiting ] [ time span: 0:00:00.000056][ result: 5 ][ trace_methods.py.Oper(39) ]
[ mul ][ entering][ args: (5) ][ kwargs: {} ][ trace_methods.py.Oper(34) ]
[ mul ][ exiting ] [ time span: 0:00:00.000010][ result: 25 ][ trace_methods.py.Oper(34) ]
[ add ][ entering][ args: (7) ][ kwargs: {} ][ trace_methods.py.Oper(39) ]
[ add ][ exiting ] [ time span: 0:00:00.000007][ result: 32 ][ trace_methods.py.Oper(39) ]
[ mul ][ entering][ args: (8) ][ kwargs: {} ][ trace_methods.py.Oper(34) ]
[ mul ][ exiting ] [ time span: 0:00:00.000008][ result: 256 ][ trace_methods.py.Oper(34) ]
256
Data Types
----------
varies derivative of Python data types
MergeChainedDict
~~~~~~~~~~~~~~~~
Similar to ChainedDict, but merged the keys and is actually derivative of dict.
.. code-block:: python
a={1:11, 2:22}
b={3:33, 4:44}
c={1:55, 4:66}
d=MergedChainedDict(c, b, a)
print(d)
Will output:
.. code-block:: python
{1: 55, 2: 22, 3: 33, 4: 66}
Mediator
--------
Class interface to generator allowing query of has_next()
Example
~~~~~~~
.. code-block:: python
from acris import Mediator
def yrange(n):
i = 0
while i < n:
yield i
i += 1
n = 10
m = Mediator(yrange(n))
for i in range(n):
print(i, m.has_next(3), next(m))
print(i, m.has_next(), next(m))
Example Output
~~~~~~~~~~~~~~
.. code-block:: python
0 True 0
1 True 1
2 True 2
3 True 3
4 True 4
5 True 5
6 True 6
7 True 7
8 False 8
9 False 9
Traceback (most recent call last):
File "/private/var/acrisel/sand/acris/acris/acris/example/mediator.py", line 19, in <module>
print(i, m.has_next(), next(m))
File "/private/var/acrisel/sand/acris/acris/acris/acris/mediator.py", line 38, in __next__
value=next(self.generator)
