Slop is a simple, lightweight command-line option parser for Ruby with an easy-to-remember syntax and friendly API. It supports typed options (string, integer, bool, etc.), defaults, required flags, and custom option types.

Use cases

• parse command-line flags in a ruby script
• build a CLI tool with options and subcommands
• define required and optional arguments with defaults
• parse boolean flags and typed values like integers
• add a --version flag to a command-line app
• replace optparse with a friendlier API

When to choose

• you're writing a Ruby CLI and want minimal, readable option parsing
• you want built-in typed options and sensible defaults
• you're a beginner looking for an approachable parser

When to avoid

• you need complex subcommand routing or advanced CLI frameworks like thor
• you're not working in Ruby
• you need extremely high-performance argument parsing
