About This Repository

This repository contains the source code for the T-Ruby official documentation website.

The documentation site is built with Docusaurus and supports multiple languages (English, Korean, Japanese).

What is T-Ruby?

T-Ruby is a typed superset of Ruby that compiles to plain Ruby — just like TypeScript does for JavaScript.

• Write .trb files with type annotations
• Compile to standard .rb files with zero runtime overhead
• Automatically generate .rbs signature files for type checkers

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

# output.rb (compiled)
def greet(name)
  "Hello, #{name}!"
end

# output.rbs (generated)
def greet: (String name) -> String
