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

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

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

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.

Parameter Validation and Type Coercion for Rails

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 converti...

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

Easily filters type coercion in jsonapi-resources.

Provides coercions for ActiveModel objects

gem to facilitate automatic coercion between jruby/java objects

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

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

Type Coercion & Type Enhancement

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.

Rack parameter validation and type coercion.

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

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

A simple type coercion library

A global Boolean2 constant that is an ancestor of true and false. Useful for coercion libraries.

A small library for manipulating form-based data with validations and attributes coercion.
