AWS Step Function State Language Builder (awssl)

The awssl package generates JSON that is compliant with the Amazon States Language (ASL), declaring State Machines for use in the AWS Step Function service:

import awssl

hello_world = awssl.Pass(
        Name="HelloWorld",
        ResultAsJSON={"Hello": "World!"},
        EndState=True)

sm = awssl.StateMachine(
        Comment="A Hello World example of the Amazon States Language using a Pass state",
        StartState=hello_world)

print sm

Which creates the following JSON:

{
    "Comment": "A Hello World example of the Amazon States Language using a Pass state",
    "StartAt": "HelloWorld",
    "States": {
        "HelloWorld": {
            "Comment": "",
            "End": true,
            "InputPath": "$",
            "OutputPath": "$",
            "Result": {
                "Hello": "World!"
            },
            "ResultPath": "$",
            "Type": "Pass"
        }
    },
    "Version": "1.0"
}
