Haskell Interactive Notebook

Haskell Notebook for VS Code — Seeking Community Feedback

What I’m building

A lightweight VS Code extension for interactive Haskell notebooks (.ihsnb → i for interactive | hs for haskell | nb for notebook) — no Jupyter, no Python, no ZeroMQ. Just GHCi, native VS Code APIs, and a clean workflow for literate Haskell.

Tech stack

• TypeScript + VS Code Extension API using Notebook API

• GHCi (–interactive) for evaluation

• Custom parser for GHCi output

• Markdown + code cells, persistent outputs, :t history

Community help would be amazing

Autocompletion: Implement native completions via :complete

HLS integration: Hover types, diagnostics, go-to-definition inside cells

State management: Isolate or reset context per cell

Testing & docs: Expand test coverage and contributor guides

If you’ve worked with GHCi internals, LSP, or VS Code extension dev — your insights would accelerate this project significantly. Even small feedback on UX or architecture is invaluable.

Compatibility Note: This extension has currently only been tested with Haskell Platform 8.6.5 , chosen for its straightforward installation process on Windows. Feedback, testing reports, and compatibility fixes for newer GHC versions or other operating systems are highly welcome!
