mr-graph 0.2.6

A graph definition execution library for async/sync python functions.

Mr. Graph

Welcome to Mr. Graph!

Mr. Graph is a python library designed to make composing graphs of sync and async functions easy! Use google style docstrings to automagically create dataclasses and chain together function calls into graphs.

Features

• Use with either async or sync functions
• Uses google style doc strings to name return values.
• Creates dataclasses for each function's output.
• Can infer pipelines from input and output signatures
• All directed acyclic graph layouts supported. linear, fan-in, fan-out.

Example Usage

Building graphs can be as easy as:

from mr_graph import Graph

def return_one():
    """
    return 1

    return one with no inputs

    Returns
    -------
    m : float
        equal to 1
    """
    return 1
    
async def add_1(m: float):
    """
    add 1 to a number

    add 1 to the input value n.

    Parameters
    ----------
    n : float
        number to add 1 to.

    Returns
    -------
    n : float
        equal to n + 1
    """
    return n + 1

async def build_implicit_linear_graph():
    """
    Return 2

    Simple example linear graph. Wired up automagically using the input and output variable names.

    Parameters
    ----------
    
    Returns
    -------
    two : float
        always equal to 2
    """

    g = Graph(nodes=[return_one, add_1])
    return await g()
