Project Description

Pyppo is a simple flow base programming micro framework for Python.


Simple pipeline

This is an example of a very simple pipeline. Simply pass a list functions to be executed at the pipeline execution.

obj = []

def do_something(obj):
    return obj

def do_something_else(obj):
    return obj

consume(pipeline([obj], [do_something, do_something_else]))

[1, 2]

Fork pipeline

This example shows a fork of a pipeline. fork is essentially another pipeline steps except it acceptes a list of function branches.

obj = []
def first_step(obj):
    return obj

def branch_add_two(obj):
    return obj

def branch_add_four(obj):
    return obj

pipeline([obj], first_step, fork([branch_add_two], [branch_add_four]))

Validate pipeline steps

You can also validate pipeline steps by providing a validate function to the validate_with decorator as shown on the following example

validation = lambda entry: 'x' in entry

def add_x_to_entry(entry):
    # should add 'x' key to entry dictionary but didn't
    return entry

def increment_1_on_x_key(entry):
    entry['x'] += 1
    return entry

entry = {}
# consume will saise a StepValidationError
consume(pipeline([entry], [add_x_to_entry, increment_1_on_x_key]))
