What is Haskell Formatter?
Haskell Formatter is a specialized tool designed to format and beautify Haskell code according to community standards and functional programming best practices. Haskell is a purely functional programming language known for its strong type system, lazy evaluation, and mathematical elegance, used in academic research, financial systems, and high-assurance applications, requiring consistent formatting for maintainable and readable code.
Our Haskell formatter ensures your code follows established Haskell Style Guide conventions and maintains consistency across your development team and projects, embracing Haskell's philosophy of mathematical beauty and functional purity.
Key Benefits:
- Functional Programming Excellence: Apply Haskell Style Guide and community-driven formatting conventions automatically
- Type System Organization: Structure type signatures, type classes, and advanced type-level programming clearly
- Modern GHC Features: Support for GHC extensions, type families, GADTs, and advanced Haskell language features
- Mathematical Clarity: Format code to highlight mathematical relationships and functional composition
- Academic Standards: Structure code for research, formal verification, and high-assurance system development
Perfect for Haskell developers, functional programming researchers, and development teams working with financial systems, compilers, and mathematical computing applications.

How to Use Haskell Formatter:
- Upload your Haskell file or paste functional programming code directly into the editor
- Select your preferred formatting options (Haskell Style Guide, indentation, type system settings)
- Click "Format" to apply Haskell best practices and improve code readability
- Use fullscreen mode for large projects and complex type-level programming
- Copy the formatted output for development or integrate with Haskell tools and GHC
Integration Support: Works seamlessly with Haskell development tools including VS Code with Haskell extensions, Emacs with haskell-mode, and build systems like Cabal and Stack. Compatible with modern GHC versions and popular libraries from Hackage.
