Lightweight structured logging for Ruby applications

A Ruby library for terminal text styling with ANSI colors and effects. Provides an elegant, functional API with immutable style objects that can be composed using the >> operator. Supports standard colors, hex values, and comprehensive text effects including bold, faint, italic, underline, overline, blink, inverse, and concealed text. Features type-safe argument validation using dry-schema and dry-types.

Scope Hunter is a RuboCop extension that detects ActiveRecord query chains that duplicate existing named scopes and suggests using those scopes instead. It indexes model scopes, canonicalizes relation chains, and flags matches with an autocorrect that replaces the initial query with Model.scope while preserving any trailing methods. This keeps query logic DRY, improves readability, and helps teams discover and reuse well-named scopes.

ActiveDryDeps does not modify constructor and supports Dependency Injection for modules. Also you can import method from any object in your container. Adding extra dependencies is easy and improve readability your code.

Dry::Workflow allows developers to define complex, multi-step business processes with a clear DSL. It supports `step`, `map`, and `try` operations, similar to dry-transaction, but with an added emphasis on defining and executing rollback procedures for each step if the workflow fails. This helps ensure data consistency and provides a structured way to handle failures in long-running or critical operations.
