Language comparison
Key differences between Haskell and Raku
| Characteristic | Haskell | Raku |
|---|---|---|
| Syntax | Purely functional, uses significant whitespace, concise and mathematical, relies heavily on pattern matching and type inference. | Multi-paradigm, Perl-inspired, uses sigils, braces, and flexible syntax, supports grammars and custom operators. |
| Paradigm | Pure functional programming with strong emphasis on immutability and higher-order functions. | Multi-paradigm: supports procedural, object-oriented, functional, and concurrent programming. |
| Typing | Statically typed with strong, inferred types; uses Hindley-Milner type system. | Dynamically typed by default, but supports gradual typing and optional type annotations. |
| Performance | Generally fast for functional workloads, but can be slower than low-level languages; performance depends on lazy evaluation and optimization. | Slower than many mainstream languages due to its flexibility and dynamic features; performance is improving but still lags behind Haskell. |
| Libraries and frameworks | Rich ecosystem for functional programming, web development, and concurrency; package management via Hackage and Stack. | Growing but smaller ecosystem; modules available via the Raku ecosystem (zef); fewer mature frameworks. |
| Community and support | Active academic and open-source community, good documentation, strong presence in research and some industry sectors. | Smaller but passionate community, strong ties to Perl community, less industry adoption, documentation is improving. |
| Learning curve | Steep learning curve due to pure functional paradigm, advanced type system, and abstract concepts. | Moderate learning curve; flexible syntax can be both a help and a hindrance, easier for those with Perl background. |
Common questions
Frequently Asked Questions
How do I convert Haskell to Raku?
Paste your Haskell code into the input box, confirm the languages are set to Haskell and Raku, and click Convert. CodeConvert AI analyzes your Haskell code and generates equivalent Raku code in seconds, preserving the original logic and structure.
What are the main differences between Haskell and Raku?
Haskell 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 Haskell construct to its closest Raku equivalent. See the comparison table below for the key differences between Haskell and Raku.
Is the converted Raku code accurate?
The AI produces high-quality Raku code that preserves the behavior of your original Haskell code and follows Raku conventions. It handles common patterns, data structures, and idioms for both Haskell and Raku. For large or performance-critical code, review and test the Raku output before using it in production.
Can I convert an entire Haskell project to Raku?
You can convert Haskell 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 Haskell to Raku. Signing in for free raises the input limit to 25,000 characters per conversion for larger files.
Can I convert Raku back to Haskell?
Yes. CodeConvert AI converts in both directions, so you can convert Raku to Haskell just as easily using our Raku to Haskell converter. Try the Raku to Haskell Converter
Is the Haskell to Raku converter free, and do I need to install anything?
Yes, it is free and runs in your browser with nothing to install and no IDE extension required. You can convert Haskell to Raku without an account for up to 5 conversions per day. Sign in for free for higher limits.
What are the benefits of signing in?
Signing in unlocks CodeConvert AI's Pro converter with more powerful AI models, a built-in chat assistant, code execution, saved conversion history, and personal notes. Every free account includes 5 credits and supports up to 25,000 characters of input per conversion, with no credit card required.
