Sorbet's runtime type checking component

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

RDL is a gem that adds types and contracts to Ruby. RDL includes extensive support for specifying method types, which can either be enforced as contracts or statically checked.

Type checking and type casting of parameters for Action Pack

A gem that provides DSL for serialization of plain old Ruby objects to JSON in a declarative style by defining a `schema`. It also provides a trivial type checking in the runtime before serialization.

Type check JSON objects

MooseX is an extension of Ruby object DSL. The main goal of MooseX is to make Ruby Object Oriented programming easier, more consistent, and less tedious. With MooseX you can think more about what you want to do and less about the mechanics of OOP. It is a port of Moose/Moo from Perl to Ruby world, providing method delegation, type check, traits, monads, plugins, lazy attributes, aspects and much more.

A puppet-lint plugin to check for classes and defined types that contain names beginning with a digit.

Yadriggy builds the abstract syntax tree (AST) of a method, checks its syntax and types, and runs it. When checking the syntax and types, it is treated as the code written in a domain specific language (DSL). It also provide simple DSLs for computation offloading from Ruby to C, Python, etc.

Cerealize your ActiveModel objects into flat hashes with a dead simple, yet versatile DSL, and caching and type-checking baked in. Our daily bread is to make your API faster.

Makes sure users don't accidentally create an account for the wrong e-mail address. Because 'gmial' isn't actually what they meant to type. Similarly, 'yaho.com', or the strange-but-true '.c0m'. Not even making that one up. If you're concerned about false-positives, it's super-easy to check. There's only a single method. Also, it's fully-tested.

A puppet-lint plugin to check that Optional class/defined type parameters don't default to anything other than `undef`.

Type-checked serializers for your Ruby objects

A new check for puppet-lint that validates that all parameters are typed.

A modern modular service object toolkit for Rails, that respects database transactions and adds type checks to returned values.

A dynamic type checker for gRPC methods

The Preconditions library provides a simple set of methods for checking arguments being passed into a method. Instead of writing custom checks and raising exceptions directly in your code you can use Preconditions to verify basic properties of your arguments (not-nil, satisfying a boolean expression, being of a certain type/duck-type) and raise the appropriate exception for you.

All the flexibility of a Ruby Struct, but with type checking on its properties. Also benefit from being able to define complex types using RBS type notation.

All methods that alter the contents of an array that implements this Gem are first checked to ensure that the added items are of the types allowed. All methods behave exactly as their Array counterparts, including additional forms, block processing, etc. Defining a TypedArray Class: ```ruby class ThingsArray < Array extend TypedArray restrict_types Thing1, Thing2 end things = ThingsArray.new ``` Generating a single TypedArray ```ruby things = TypedArray(Thing1,Thing2).new These classes can be extended, and their accepted-types appended to after their initial definition.

Check yardoc format like tag type.
