Language comparison
Key differences between Ruby and Raku
| Characteristic | Ruby | Raku |
|---|---|---|
| Syntax | Clean, elegant, and inspired by Perl but simplified; uses end keywords for blocks. | More flexible and expressive; supports multiple syntactic forms and custom operators. |
| Paradigm | Primarily object-oriented, also supports functional and imperative programming. | Multi-paradigm: object-oriented, functional, concurrent, and declarative programming. |
| Typing | Dynamically typed, duck typing, no static type checking. | Gradually typed; supports both dynamic and static typing with optional type constraints. |
| Performance | Generally slower than many compiled languages; mature interpreters (MRI, JRuby) with moderate performance. | Slower than Ruby in most cases due to its complex features and younger implementations. |
| Libraries and frameworks | Rich ecosystem, especially for web development (e.g., Rails, Sinatra); extensive gems repository. | Smaller ecosystem; fewer libraries and frameworks, but growing with modules on the Raku ecosystem. |
| Community and support | Large, active, and mature community with extensive documentation and support. | Smaller, passionate community; less mainstream support and fewer resources. |
| Learning curve | Gentle learning curve; beginner-friendly syntax and lots of learning resources. | Steeper learning curve due to advanced features and flexible syntax; fewer beginner resources. |
Common questions
Frequently Asked Questions
How do I convert Ruby to Raku?
Paste your Ruby code into the input box, confirm the languages are set to Ruby and Raku, and click Convert. CodeConvert AI analyzes your Ruby code and generates equivalent Raku code in seconds, preserving the original logic and structure.
What are the main differences between Ruby and Raku?
Ruby and Raku differ in syntax, type system, standard libraries, and common idioms, so copying code line for line usually will not compile. The converter maps each Ruby construct to its closest Raku equivalent. See the comparison table below for the key differences between Ruby and Raku.
Is the converted Raku code accurate?
The AI produces high-quality Raku code that preserves the behavior of your original Ruby code and follows Raku conventions. It handles common patterns, data structures, and idioms for both Ruby and Raku. For large or performance-critical code, review and test the Raku output before using it in production.
Can I convert an entire Ruby project to Raku?
You can convert Ruby files one at a time by pasting each file's code. For a full migration, convert each file and then review how classes, dependencies, and project structure map from Ruby to Raku. Signing in for free raises the input limit to 25,000 characters per conversion for larger files.
