leejarvis/slop

This system is the Slop library, a command-line argument parser for Ruby. It provides a modular architecture for defining, parsing, and validating command-line options, supporting various data types and structured error handling. The project includes a comprehensive test suite using Minitest to verify parsing logic and option configuration.

The \lib/slop\ library has been rewritten for version 4.0, introducing a modular architecture with separate files for options, parsing, and result handling. Users now have access to new built-in option types including \Symbol\, \Regexp\, and \Array\ (with configurable delimiters and limits), alongside existing \String\, \Integer\, \Float\, and \Bool\ types. The parser now supports \--no-\ prefixes for inverting boolean options, grouped short flags (e.g., \-abc\), and strict type validation via the \validate\_types\ config option. Error handling is more granular, with distinct exception classes (\MissingArgument\, \UnknownOption\, \MissingRequiredOption\, \InvalidOptionValue\) that can be suppressed globally. The API exposes \Result\#fetch\ for safe option retrieval, \Result\#to\_hash\ for serialization, and tracks option usage counts and tail arguments.

lib/slop · high confidence

The Slop command-line parsing library has been completely rewritten, upgrading the version from 0.1.0 to 4.10.1. The internal structure has shifted from a single monolithic class to a modular design using separate files for options, parsing, results, types, and errors. The public API has changed significantly: \Slop.parse\ now accepts a configuration hash and returns a \Slop::Result\ object instead of the \Slop\ instance itself, and new class methods like \option\_defined?\ and \string\_to\_option\ have been added to support dynamic option handling.

lib · high confidence

Initial test suite for Slop command-line parser; Removed legacy RSpec test suite.

The project now uses a Gemfile that loads the gemspec, simplifying dependency management. The gemspec has been updated to read the version from the codebase (Slop::VERSION) instead of hardcoding it, switched the test framework from RSpec to Minitest (version \~\> 5.0.0), added Rake as a development dependency, specified the MIT license, and raised the minimum required Ruby version to 2.0.0.
