This free online converter translates Wren source code into Haskell in three simple steps.
- Step 1
Add your Wren code
Type, paste, or upload the Wren code you want to translate.
- Step 2
Convert the code
Click Convert to translate the source code into Haskell.
- Step 3
Review the result
Review, copy, or download the resulting Haskell code from the output editor.
Language comparison
Key differences between Wren and Haskell
| Characteristic | Wren | Haskell |
|---|---|---|
| Syntax | C-like, minimalistic, concise, and easy to read; uses braces and semicolons. | Whitespace-sensitive, functional, uses significant indentation and mathematical notation. |
| Paradigm | Primarily object-oriented with some scripting features. | Purely functional and declarative. |
| Typing | Dynamically typed. | Statically typed with strong type inference. |
| Performance | Designed for fast scripting and embedding; generally fast for a scripting language. | Can be highly performant due to optimizations, but performance depends on code style and compiler. |
| Libraries and frameworks | Limited ecosystem; fewer libraries and frameworks. | Rich ecosystem with many libraries and frameworks, especially for functional programming. |
| Community and support | Small but growing community; limited resources. | Large, established community with extensive documentation and support. |
| Learning curve | Gentle learning curve, especially for those familiar with C-like languages. | Steep learning curve due to functional paradigm and advanced type system. |
Common questions
Frequently Asked Questions
How do I convert Wren to Haskell?
Paste your Wren code into the input box, confirm the languages are set to Wren and Haskell, and click Convert. CodeConvert AI analyzes your Wren code and generates equivalent Haskell code in seconds, preserving the original logic and structure.
What are the main differences between Wren and Haskell?
Wren and Haskell differ in syntax, type system, standard libraries, and common idioms, so copying code line for line usually will not compile. The converter maps each Wren construct to its closest Haskell equivalent. See the comparison table below for the key differences between Wren and Haskell.
Is the converted Haskell code accurate?
The AI produces high-quality Haskell code that preserves the behavior of your original Wren code and follows Haskell conventions. It handles common patterns, data structures, and idioms for both Wren and Haskell. For large or performance-critical code, review and test the Haskell output before using it in production.
Can I convert an entire Wren project to Haskell?
You can convert Wren 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 Wren to Haskell. Signing in for free raises the input limit to 25,000 characters per conversion for larger files.
Can I convert Haskell back to Wren?
Yes. CodeConvert AI converts in both directions, so you can convert Haskell to Wren just as easily using our Haskell to Wren converter. Try the Haskell to Wren Converter
Is the Wren to Haskell 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 Wren to Haskell without an account for up to 2 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.
