Working hard on Rad, which is aiming to be a Bash-replacement for writing CLI scripts. The goal is to allow users to write maintainable scripts with declarative argument parsing, built-in JSON processing, HTTP requests, and interactive prompts - all in a familiar, readable syntax (Python-like!). Here's an example of the declarative approach to script args:

  args:
      username str           # Required string
      password str?          # Optional string
      token str?             # Optional auth token
      age int                # Required integer
      status str             # Required string
  
      username requires password     // If username is provided, password must also be provided
      token excludes password        // Token and password cannot be used together
      age range [18, 99]             // Inclusive range from 18 to 99
      status enum ["active", "inactive", "pending"]

Rad does all the arg parsing for you (unlike Bash), including validation for those constraints you wrote, and you can get on with writing the rest of your script is a nice, friendly syntax!

Very keen for feedback so if any of that sounds interesting, feel free to give it a go!
