Renders and parses JSON/XML/YAML documents from and to Ruby objects. Includes plain properties, collections, nesting, coercion and more.

Type system for Ruby supporting coercions, constraints and complex types like structs, value objects, enums etc

Powerful, flexible and configurable coercion library. And nothing more.

dry-schema provides a DSL for defining schemas with keys and rules that should be applied to values. It supports coercion, input sanitization, custom types and localized error messages (with or without I18n gem). It's also used as the schema engine in dry-validation.

Myrrha provides the coercion framework which is missing to Ruby. Coercions are simply defined as a set of rules for converting values from source to target domains (in an abstract sense). As a typical and useful example, it comes with a coerce() method providing a unique entry point for converting a string to a numeric, a boolean, a date, a time, an URI, and so on.

A type coercion lib works with Sorbet's static type checker and type definitions; raises an error if the coercion fails.

Parameter Validation and Type Coercion for Rails

Type Coercion & Type Enhancement

gem to facilitate automatic coercion between jruby/java objects

Easily filters type coercion in jsonapi-resources.

Provides coercions for ActiveModel objects

setters with type coercion for set* methods on java classes using the jruby coercion interface `to_java(java_type)`

Generates modules that provide conventional value semantics for a given set of attributes. The behaviour is similar to an immutable `Struct` class, plus extensible, lightweight validation and coercion.

Schema-based validation and coercion for Ruby data structures, inspired by Prismatic/schema for Clojure.

Rack parameter validation and type coercion.

Provides a DSL for generating immutable Ruby Data objects with type coercion and data transformation capabilities.

Clock interface with support for UTC and local timezones, timezone coercion, and dependency substitution

Access environment variables. Also includes presence validation, type coercion and default values.

Simple and composable validation and coercion of data structures inspired by clojure specs

FlexCoerce - is a gem which allow you create operator-dependent coercion logic. It's useful when your type should be treated in a different way for different binary operations (including arithmetic operators, bitwise operators and comparison operators except equality checks: `==`, `===`).
