Welcome to ``aws_stepfunction`` Documentation
==============================================================================
.. note::

    You may not viewing the full document, `FULL DOCUMENT IS HERE <https://aws-stepfunction.readthedocs.io/index.html>`_

**Why this Library?**

``aws_stepfunction`` provides AWS StepFunction developer a "smooth", "interruption free", "enjoyable" development experience.

If your mind set matches most of the following, ``aws_stepfunction`` is the right tool for you:

- I love the AWS StepFunction Visual Editor
- I love Python
- I don't want to spent much time learning the Amazon State Machine JSON DSL (Domain Specific Language)
- I can't memorize the code syntax
- I respect code readability and maintainability

**Talk is cheap, show me the code**

The following code snippet is an equivalent of the below Workflow in the Visual Editor

.. code-block:: python

    import aws_stepfunction as sfn
    from boto_session_manager import BotoSesManager

    # Declare a workflow object
    workflow = sfn.Workflow(comment="The power of aws_stepfunction library!")

    # Define some tasks and states
    task_invoke_lambda = sfn.actions.lambda_invoke(func_name="stepfunction_quick_start")
    succeed = sfn.Succeed()
    fail = sfn.Fail()

    # Orchestrate the Workflow
    (
        workflow.start_from(task_invoke_lambda)
        .choice([
            (  # define condition
                sfn.not_(sfn.Var("$.body").string_equals("failed!"))
                .next_then(succeed)
            ),
            (  # define condition
                sfn.Var("$.body").string_equals("failed!")
                .next_then(fail)
            ),
        ])
    )

    # Declare an instance of State Machine
    state_machine = sfn.StateMachine(
        name="stepfunction_quick_start",
        workflow=workflow,
        role_arn="arn:aws:iam::111122223333:role/my_lambda_role",
    )

    # Deploy state machine
    bsm = BotoSesManager(profile_name="my_aws_profile", region_name="us-east-1")
    state_machine.deploy(bsm)

    # Execute state machine with custom payload
    state_machine.execute(bsm, payload={"name": "alice"})

    # delete step function
    state_machine.delete(bsm)
