ex_cli

The clean DSL reduces boilerplate by allowing intuitive definition of commands, options, and arguments, as shown in the README example with commands like :hello and options like :verbose.

It generates formatted usage instructions and command descriptions automatically, saving manual effort—evident from the usage output when parsing fails.

ExCLI integrates directly with Elixir's Mix tasks and escripts, enabling the same CLI definitions for both, as demonstrated in the integration sections.

Supports short aliases for commands and provides a context object with parsed data, improving user experience and developer access, like using 'hi' as an alias for 'hello'.
