It’s hanging out in a private repo with a bunch of other stuff and I don’t care to put it in it’s own repo at the moment. Basically CloudFormation publishes a JSON spec of all of their resource types and I use that to generate Python code with type annotations. It’s sort of like Troposphere, but I go further—Tropo makes you reference resources by their cloudformation string names, but my tool lets you use the Python object containing the resource and it will resolve to the correct CloudFormation “Ref” object at compile time. (also, unlike tropo, I generated my Python types from a spec so I don’t have to keep up with AWS changes). That said, I’ve given up on CloudFormation altogether since Terraform has better support for resources outside of AWS.
