Project description

Sprinkler
=========
A small python library that helps you write co-routines
in an event-driven way. In short it 'sprinkles' data passed
to the '.sprinkle' function to all sub-classes of 'Task' in
a round robin manner.

A simple example:

from pysprinkler import Task, Sprinkler

class RemoteDBHandler(Task):

def __init__(self):
print("Started RemoteDBHandler")

def on_data(self, data):
print("RemoteDBHandler: {}".format(data))

def on_end(self):
print("Closing RemoteDBHandler")


class LocalDBHandler(Task):

def __init__(self):
print("Started LocalDBHandler")

def on_data(self, data):
print("LocalDBHandler: {}".format(data))

def on_end(self):
print("Closing LocalDBHandler")

class STNHandler(Task):

def __init__(self):
print("Started STNHandler")

def on_data(self, data):
print("STNHandler: {}".format(data))

def on_end(self):
print("Closing STNHandler")

rdb_handler = RemoteDBHandler()
ldb_handler = LocalDBHandler()
stn_handler = STNHandler()

s = Sprinkler([rdb_handler, ldb_handler, stn_handler])
s.start()

lines = ["Line 1", "Line 2", "Line 3", "Line 4", "Line 5"]
for line in lines:
# sends 'line' to all 'Task's in a
# round robin manner
s.sprinkle(line)
s.close()

Output:

Started RemoteDBHandler
Started LocalDBHandler
Started STNHandler
RemoteDBHandler: Line 1
LocalDBHandler: Line 1
STNHandler: Line 1
RemoteDBHandler: Line 2
LocalDBHandler: Line 2
STNHandler: Line 2
RemoteDBHandler: Line 3
LocalDBHandler: Line 3
STNHandler: Line 3
RemoteDBHandler: Line 4
LocalDBHandler: Line 4
STNHandler: Line 4
RemoteDBHandler: Line 5
LocalDBHandler: Line 5
STNHandler: Line 5
Closing RemoteDBHandler
Closing LocalDBHandler
Closing STNHandler
