Introducing T-Ruby

We're excited to introduce T-Ruby, a TypeScript-style static type system for Ruby.

T-Ruby brings the familiar TypeScript development experience to Ruby developers, allowing you to add type annotations directly in your code and catch type errors before runtime.

Key Features​

  • TypeScript-style syntax: Familiar type annotation syntax for TypeScript developers
  • Gradual typing: Add types incrementally to your existing Ruby codebase
  • RBS generation: Automatically generate .rbs signature files
  • Zero runtime overhead: Types are stripped at compile time

Getting Started​

Install T-Ruby and start adding types to your Ruby code:

gem install t-ruby

Create your first .trb file:

def greet(name: String): String
  "Hello, #{name}!"
end

Compile to Ruby:

trc greet.trb
