autocommand

The proposed solution of an API with a thinly wrapped auto-generated CLI is not terrible. I have heard it is common within Google, for example. In the Python world, there are various solutions starting from https://github.com/ialbert/plac or https://argh.readthedocs.io/en/latest/ and moving on to https://github.com/pallets/click or https://github.com/Lucretiel/autocommand and probably N others. Personally, I prefer Nim to Python which has https://github.com/c-blake/cligen. As mentioned in https://github.com/c-blake/cligen/blob/master/MOTIVATION.md, but not in the borretti article, the overhead of dispatch to a program in shell REPLs can also be thousands to millions of times higher than an API call.

I was looking for something similar to click / fire that uses type annotations to validate/cast the inputs today. Came across this https://github.com/Lucretiel/autocommand I think it would be really nice to have a library that takes the type annotated functions and lets you expose them as a CLI, GUI, REST API and a web form. Practically just combining click, flask, rest framework and Gooey. Would be a great tool for data scientists. Take something like def recognize(image: Image) -> List[Prediction] preds = model(image) return preds and generate web page that lets you drop an image in and get a list of predictions
