Context

The issue motivating this decision, and any context that influences or constrains the decision.

Amazing:

• Heavy usage of python annotations
• Beautiful output
• Battery included, completion
• Functions args are actual python args/cli kwargs
• Rich library integration

Pros:

• Low initial boilerplate, low learning curve
• Provide a nested structure for sub-commands (hierarchy is managed with parent/child relationship)
• Relatively easy to start

Cons:

• Complex command lines can be make
• Changing things like help is difficult
• Executing group commands require extra function
• Documentation is extensive, but hard to follow
• Large programs does not fit well
• Not dry, we end up to duplicate always the same args everywhere, especially in large apps
• Completion and startup time is somewhat slow.
