λιβι.λ - Lambda Library

Haskell Bridge Tutorial

Connect Haskell with modern functional programming environments using type-safe interoperability patterns.

Why Haskell?

Haskell's strong static typing and purity make it an ideal foundation for building complex systems. This tutorial shows how to bridge Haskell with λιβι.λ sandbox environments.

{-- Sample Haskell type definition --}
data Expr = Lambda String Expr
| App Expr Expr
| Var String
| Const Int

FFI Bridge Patterns

Haskell Implementation

{-# LANGUAGE ForeignFunctionInterface #-}
module Bridge where
import Foreign.C.Types
import GHC.Generics

foreign export ccall evaluateExpr :: CString -> CInt

JavaScript Interoperability

// WebAssembly binding example
const libHaskell = require('./libbridge');

function evaluate(expr) {
return libHaskell.evaluateExpr(Pointer.string(expr));
}

Interactive Example

Haskell Bridge Sandbox

// Enter lambda expression:

This sandbox compiles Haskell bridge code on-the-fly and returns results via WebAssembly. No server-side processing occurs — your expressions remain private.

Practical Applications

⚙

Compiler Backends

Use Haskell's powerful type system to implement domain-specific languages that compile to λιβι.λ's functional format.

📦

Library Integration

Create Haskell packages that interface with functional JavaScript libraries while maintaining type safety.

🌐

Web APIs

Build Haskell-powered microservices that communicate with λιβι.λ's educational APIs through safe bridges.

Summary

This tutorial explored type-safe Haskell bridges for functional interoperability. You've seen how Haskell's strengths can be preserved while integrating with modern execution environments through WebAssembly and foreign function interfaces.
